    To change or not to change - translating and culturally adapting the paediatric version of the Moral Distress Scale-Revised (MDS-R)2017In: BMC Medical Ethics, ISSN 1472-6939, E-ISSN 1472-6939, Vol. 18, no 14, p. 1-9Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Paediatric cancer care poses ethically difficult situations that can lead to value conflicts about what is best for the child, possibly resulting in moral distress. Research on moral distress is lacking in paediatric cancer care in Sweden and most questionnaires are developed in English. The Moral Distress Scale-Revised (MDS-R) is a questionnaire that measures moral distress in specific situations; respondents are asked to indicate both the frequency and the level of disturbance when the situation arises. The aims of this study were to translate and culturally adapt the questionnaire to the context of Swedish paediatric cancer care. In doing so we endeavoured to keep the content in the Swedish version as equivalent to the original as possible but to introduce modifications that improve the functional level and increase respondent satisfaction.

    METHODS: The procedure included linguistic translation and cultural adaptation of MDS-R's paediatric versions for Physicians, Nurses and Other Healthcare Providers to the context of Swedish paediatric cancer care. The process of adjustment included: preparation, translation procedure and respondent validation. The latter included focus group and cognitive interviews with healthcare professionals in paediatric cancer care.

    RESULTS: To achieve a Swedish version with a good functional level and high trustworthiness, some adjustments were made concerning design, language, cultural matters and content. Cognitive interviews revealed problems with stating the level of disturbance hypothetically and items with negations caused even more problems, after having stated that the situation never happens.

    CONCLUSIONS: Translation and cultural adaptation require the involvement of various types of specialist. It is difficult to combine the intention to keep the content as equivalent to the original as possible with the need for modifications that improve the functional level and increase respondent satisfaction. The translated and culturally adapted Swedish MDS-R seems to have equivalent content as well as improved functional level and respondent satisfaction. The adjustments were made to fit paediatric cancer care but it could be argued that the changes are relevant for most areas of paediatric care of seriously ill patients.

    Mobile-based intervention intended to stop obesity in preschool-aged children: the MINISTOP randomized controlled trial2017In: American Journal of Clinical Nutrition, ISSN 0002-9165, E-ISSN 1938-3207, Vol. 105, no 6, p. 1327-1335Article in journal (Refereed)
    Abstract [en]

    Background: Traditional obesity prevention programs are time-and cost-intensive. Mobile phone technology has been successful in changing behaviors and managing weight; however, to our knowledge, its potential in young children has yet to be examined. Objective: We assessed the effectiveness of a mobile health (mHealth) obesity prevention program on body fat, dietary habits, and physical activity in healthy Swedish children aged 4.5 y. Design: From 2014 to 2015, 315 children were randomly assigned to an intervention or control group. Parents in the intervention group received a 6-mo mHealth program. The primary outcome was fat mass index (FMI), whereas the secondary outcomes were intakes of fruits, vegetables, candy, and sweetened beverages and time spent sedentary and in moderate-to-vigorous physical activity. Composite scores for the primary and secondary outcomes were computed. Results: No statistically significant intervention effect was observed for FMI between the intervention and control group (mean +/- SD: -0.23 +/- 0.56 compared with -0.20 +/- 0.49 kg/m(2)). However, the intervention group increased their mean composite score from baseline to follow-up, whereas the control group did not (+ 0.36 +/- 1.47 compared with -0.06 +/- 1.33 units; P = 0.021). This improvement was more pronounced among the children with an FMI above the median (4.11 kg/m(2)) (P = 0.019). The odds of increasing the composite score for the 6 dietary and physical activity behaviors were 99% higher for the intervention group than the control group (P = 0.008). Conclusions: This mHealth obesity prevention study in preschool-aged children found no difference between the intervention and control group for FMI. However, the intervention group showed a considerably higher postintervention composite score (a secondary outcome) than the control group, especially in children with a higher FMI. Further studies targeting specific obesity classes within preschool-aged children are warranted.

    Oxaliplatin-Induced Neurotoxic Side Effects and Their Impact on Daily Activities2019In: Cancer Nursing, ISSN 0162-220X, E-ISSN 1538-9804, Vol. 42, no 6, p. E40-E48Article in journal (Refereed)
    Abstract [en]

    Background: Oxaliplatin (OXA) is frequently used in the treatment of patients with colorectal cancer, and OXA-induced neurotoxic side effects are common. Reports on real-time patient-reported neurotoxic side effects and impact on the patient's daily activities are sparse in existing studies. Objective: The aim of this study was to identify and assess patient-reported OXA-induced neurotoxic side effects and their impact on the patient's daily activities, during and after chemotherapy. Methods: In a multicenter prospective longitudinal study, 46 chemo-naïve patients with colorectal cancer treated with postoperative adjuvant OXA-based chemotherapy were monitored during treatment and at 3-, 6-, 9-, and 12-month follow-ups. Patients were recruited from September 2013 to June 2016. In total, 370 Oxaliplatin-Associated Neurotoxicity Questionnaire responses were available for analysis. A mobile phone-based system was used to receive real-time assessments. Results: All patients reported neurotoxic side effects and impact on daily activities during treatment. The side effects changed in character and body location over time and had an impact on the daily activities. Conclusions: The high prevalence of OXA-induced neurotoxic side effects significantly interfered with the patients' daily activities. We found significant differences between baseline data and follow-up time points for neurotoxicity, and the patients had not returned to baseline after 1 year. Implications for Practice: The real-time assessment using mobile phone technology seems to be a valuable tool for monitoring patient-reported neurotoxicity and interventions for tailored care. Effectively identifying neurotoxicity and its impact on the patient's daily activities is important in supportive cancer care.

    Interrater reliability of the injury reporting of the injury surveillance system used in international athletics championships2018In: Journal of Science and Medicine in Sport, ISSN 1440-2440, E-ISSN 1878-1861, Vol. 21, no 9, p. 894-898Article in journal (Refereed)
    Abstract [en]

    Objectives: The quality of epidemiological injury data depends on the reliability of reporting to an injury surveillance system. Ascertaining whether all physicians/physiotherapists report the same information for the same injury case is of major interest to determine data validity. The aim of this study was therefore to analyse the data collection reliability through the analysis of the interrater reliability. Design: Cross-sectional survey. Methods: During the 2016 European Athletics Advanced Athletics Medicine Course in Amsterdam, all national medical teams were asked to complete seven virtual case reports on a standardised injury report form using the same definitions and classifications of injuries as the international athletics championships injury surveillance protocol. The completeness of data and the Fleiss kappa coefficients for the inter-rater reliability were calculated for: sex, age, event, circumstance, location, type, assumed cause and estimated time-loss. Results: Forty-one team physicians and physiotherapists of national medical teams participated in the study (response rate 89.1%). Data completeness was 96.9%. The Fleiss kappa coefficients were: almost perfect for sex (k = 1), injury location (k = 0.991), event (k = 0.953), circumstance (k = 0,942), and age = 0.870), moderate for type (k = 0.507), fair for assumed cause (k = 0.394), and poor for estimated time loss (k = 0.155). Conclusions: The injury surveillance system used during international athletics championships provided reliable data for "sex", "location", "event", "circumstance", and "age". More caution should be taken for "assumed cause" and "type", and even more for "estimated time-loss". This injury surveillance system displays satisfactory data quality (reliable data and high data completeness), and thus, can be recommended as tool to collect epidemiology information on injuries during international athletics championships.

    Illnesses during 11 international athletics championships between 2009 and 2017: incidence, characteristics and sex-specific and discipline-specific differences2019In: British Journal of Sports Medicine, ISSN 0306-3674, E-ISSN 1473-0480, Vol. 53, no 18, p. 1174-1182Article in journal (Refereed)
    Abstract [en]

    Background Illnesses impair athletes’ participation and performance. The epidemiology of illness in athletics is limited.

    Objective To describe the occurrence and characteristics of illnesses during international athletics championships (indoor and outdoor), and to analyse differences with regards to athletes’ sex and participation in explosive and endurance disciplines.

    Methods During 11 international championships held between 2009 and 2017, physicians from both national medical teams and the local organising committees reported daily on all athlete illnesses using a standardised report form. Illness frequencies, incidence proportions (IPs) and rates (IRs), and relative risks (RR) with 95% CIs were calculated.

    Results During the 59 days of the 11 athletics championships, 546 illnesses were recorded in the 12 594 registered athletes equivalent to IP of 43.4 illnesses per 1000 registered athletes (95% CI 39.8 to 46.9) or IR of 1.2 per 1000 registered athlete days (95% CI 1.1 to 1.2). The most frequently reported illnesses were upper respiratory tract infections (18.7%), exercise-induced fatigue/hypotension/collapse (15.4%) and gastroenteritis (13.2%). No myocardial infarction was recorded. A total of 28.8% of illnesses were expected to lead to time loss from sport. The illness IP was similar in male and female athletes, with few differences in illness characteristics. During outdoor championships, the illness IP was higher in endurance than explosive disciplines (RR=1.87; 95% CI 1.58 to 2.23), with a considerably higher IP of exercise-induced illness in endurance disciplines, but a similar upper respiratory tract infection IP in both discipline groups.

    Conclusions Illness prevention strategies during international athletics championships should be focused on the most frequent diagnoses in each discipline group.

    Elite football teams that do not have a winter break lose on average 303 player-days more per season to injuries than those teams that do: a comparison among 35 professional European teams2019In: British Journal of Sports Medicine, ISSN 0306-3674, E-ISSN 1473-0480, Vol. 53, no 19, p. 1231-1235Article in journal (Refereed)
    Abstract [en]

    Objective To compare injury rates among professional mens football teams that have a winter break in their league season schedule with corresponding rates in teams that do not. Methods 56 football teams from 15 European countries were prospectively followed for seven seasons (2010/2011-2016/2017)-a total of 155 team-seasons. Individual training, match exposure and time-loss injuries were registered. Four different injury rates were analysed over four periods within the season, and linear regression was performed on team-level data to analyse the effect of winter break on each of the injury rates. Crude analyses and analyses adjusted for climatic region were performed. Results 9660 injuries were reported during 1 447 011 exposure hours. English teams had no winter break scheduled in the season calendar: the other European teams had a mean winter break scheduled for 10.0 days. Teams without a winter break lost on average 303 days more per season due to injuries than teams with a winter break during the whole season (pamp;lt;0.001). The results were similar across the three periods August-December (p=0.013), January-March (pamp;lt;0.001) and April-May (p=0.050). Teams without a winter break also had a higher incidence of severe injuries than teams with a winter break during the whole season (2.1 severe injuries more per season for teams without a winter break, p=0.002), as well as during the period JanuaryMarch (p=0.003). A winter break was not associated with higher team training attendance or team match availability. Climatic region was also associated with injury rates. Conclusions The absence of a scheduled winter break was associated with a higher injury burden, both before and during the two periods following the time that many European teams take a winter break. Teams without a winter break (English clubs) had a higher incidence of severe injuries following the time of the year that other teams (other European clubs) had their scheduled break.

    An eHealth Application of Self-Reported Sports-Related Injuries and Illnesses in Paralympic Sport: Pilot Feasibility and Usability Study2017In: JMIR Human Factors, E-ISSN 2292-9495, Vol. 4, no 4, article id e30Article in journal (Refereed)
    Abstract [en]

    Sport participation is associated with a risk of sports-related injuries and illnesses, and Paralympic athletes additional medical issues can be a challenge to health care providers and medical staff. However, few prospective studies have assessed sports-related injuries and illnesses in Paralympic sport (SRIIPS) over time. Advances in mobile phone technology and networking systems offer novel opportunities to develop innovative eHealth applications for collection of athletes self-reports. Using eHealth applications for collection of self-reported SRIIPS is an unexplored area, and before initiation of full-scale research of SRIIPS, the feasibility and usability of such an approach needs to be ascertained.

    Choice of measure matters: A study of the relationship between socioeconomic status and psychosocial resources in a middle-aged normal population2017In: PLOS ONE, E-ISSN 1932-6203, Vol. 12, no 8, article id e0178929Article in journal (Refereed)
    Abstract [en]

    Psychosocial resources may serve as an important link to explain socioeconomic differences in health. Earlier studies have demonstrated that education, income and occupational status cannot be used interchangeably as indicators of a hypothetical latent social dimension. In the same manner, it is important to disentangle the effect of measuring different constructs of psychosocial resources. The aim of this study was therefore to analyse if associations between socioeconomic status (SES) and psychosocial resources differ depending on the measures used. A cross-sectional population-based study of a random sample (n = 1007) of middle-aged individuals (45-69 years old, 50% women) in Sweden was performed using questionnaire and register data. SES was measured as education, occupation, household income and self-rated economy. Psychosocial resources were measured as social integration, social support, mastery, self-esteem, sense of coherence (SOC) and trust. Logistic regression models were applied to analyse the relationships controlling for the effects of possible confounders. The measures of SES were low or moderately correlated to each other as were the measures of psychosocial resources. After controlling for age, sex, country of birth and employment status, household income and self-rated economy were associated with all six psychosocial resources; occupation was associated with three (social integration, self-esteem and trust) and education with two (social integration and self-esteem). Social integration and self-esteem showed a significant and graded relationship with all SES measures; trust was associated with all SES measures except education, whereas SOC and mastery were only associated with household income and self-rated economy. After controlling for other SES measures, no associations with psychosocial resources remained for education or occupation. In conclusion, associations between SES and psychosocial resources did differ depending on the measures used. The findings illustrate the importance of the choice of measure when investigating SES as well as psychosocial resources.

    Maintaining motivation and health among recreational runners: Panel study of factors associated with self-rated performance outcomes at competitions2019In: Journal of Science and Medicine in Sport, ISSN 1440-2440, E-ISSN 1878-1861, Vol. 22, no 12, p. 1319-1323Article in journal (Refereed)
    Abstract [en]

    Objectives: To investigate health-related factors associated with self-rated race performance outcomes among recreational long-distance runners. Design: Panel study. Methods: Data were collected from runners one month before and after a community-level race event including distances from 8 to 42.2 km. The primary outcome measure was self-rated race performance outcome. The explanatory variables represented health complaints suffered during the build-up year, the pre-race month, and the race and among full marathon runners predicted objective performance outcome (mean pace equal to training pace or faster). Multiple logistic regression was used to determine factors associated with the self-rated performance outcome. Results: Two-hundred forty-five runners (29%) provided complete data sets. Seventy-four percent of the runners reached their desired race performance outcome. Achievement of the performance outcome was more likely when having avoided illness during the build-up and pre-race periods (OR = 3.8; 95% CI:1.8-8.0, p amp;lt; 0.001), having avoided per-race injury (OR=3.0; 95% CI:1.2-7.4, p = 0.02) and avoided perrace illness (OR= 4.1; 95% CI:1.3-15, p = 0.020). Having obtained the self-rated performance outcome was also associated with running a shorter distance (OR=3.6; 95% CI: 1.7-8.0,p = 0.001) and being younger than 50 years of age (OR= 2.4; 95% CI:1.1-5.3-8.3, p = 0.03). Having met the predicted objective performance outcome predisposed marathon runners to also obtain the self-rated performance outcome (OR= 4.7, 95% CI: 1.5-16, p amp;lt; 0.01). Conclusions: Having avoided illness during build-up and pre-race was positively associated with self-rated race performance outcome among recreational runners. Adjusting the desired performance outcomes with regard to recent illness and age may help recreational runners to more often achieve their goals and thereby prevent them from leaving the sport.

    Risk and Protective Factors for Middle- and Long-Distance Running-Related Injury2017In: Sports Medicine, ISSN 0112-1642, E-ISSN 1179-2035, Vol. 47, no 5, p. 869-886Article, review/survey (Refereed)
    Abstract [en]

    Background Despite a rapidly growing body of research, a systematic evidence compilation of the risk and protective factors for middle- and long-distance running-related injury (RRI) was lacking. Objectives Our objective was to compile the evidence about modifiable and non-modifiable training-related and behavioral risk and protective factors for middle- and long-distance RRI. Methods We searched five databases (PubMed, CINAHL, MEDLINE, SPORTDiscus, and PsycINFO) for the dates 1 January 1970 to 31 December 2015, inclusive, for original peer-reviewed articles. The eligible designs were cross-sectional, case-control, longitudinal observational studies, and randomized controlled trials involving runners competing at distances from amp;gt;= 800 m to amp;lt;= 42.2 km. Outcomes were any specific and/or general RRI, and exposures included training-related and behavioral factors. We extracted authors and date, study design, injury type(s), descriptors and comparators for each exposure, and results and measures of association from the selected studies. Methodological quality was independently appraised using two separate checklists: a modified checklist for observational study designs and the Physiotherapy Evidence Database (PEDro) scale for randomized controlled trials. Results Among 73 articles eligible for inclusion, 19 (26.0%) and 30 (41.0%) were of high or satisfactory methodological quality, respectively. As a non-modifiable exposure, a history of previous injury was found to be associated with an increased risk of both general and specific RRI. In terms of modifiable exposures, irregular and/or absent menstruation was found to be associated with an increased risk of stress fracture development, whereas the use of oral contraceptives was found to be associated with a decreased risk. High clinical, methodological, and statistical heterogeneity meant it was not feasible to estimate a pooled effect size across similar studies. Conclusions A history of previous injury was associated with an increased risk of both general and specific RRI. The use of oral contraceptives was found to be associated with a decreased risk of skeletal stress fracture. Conversely, irregular and/or absent menstruation was associated with an increased risk. The varied effect directions and/or a number of statistically insignificant results associated with the majority of factors hindered our ability to draw any definitive conclusions about their relationship to RRI risk.

    Injuries in youth track and field are perceived to have multiple-level causes that call for ecological (holistic-developmental) interventions: A national sporting community perceptions and experiences2018In: Scandinavian Journal of Medicine and Science in Sports, ISSN 0905-7188, E-ISSN 1600-0838, Vol. 28, no 1, p. 348-355Article in journal (Refereed)
    Abstract [en]

    Engaging in competitive sports as a youth can have many health benefits, but recent studies also report a high risk for injury. The long-term purpose of this Swedish research program is to develop a framework for safe track and field training for young athletes (aged 12-15years). The aim of this study was to establish what is perceived to contribute and cause injuries in youth track and field by compiling the best available experiential knowledge about the underlying factors and use this knowledge to identify appropriate areas to handle these in practical ways. Nine focus group interviews with in total 74 participants and confirming interviews with five individuals were performed in seven Swedish regions. Qualitative research methods were used for data analysis. Injuries in youth athletes were not considered to be strictly the result of individual factors but rather the result of the interactions between factors at different levels. Three major factors emerged as follows: Insufficient knowledge for athletic development in daily practice; shortsighted communities of practice and sports policies not adjusted to youth; and societal health behaviors. The experiential knowledge in the national sporting community suggests that if effective and sustainable injury prevention processes are to be implemented for youth track and field, an ecological (holistic-developmental) approach to injury prevention is needed. Such an approach allows a longitudinal development-focused strategy for prevention that spans an athletes entire career.

    Can physical activity compensate for low socioeconomic status with regard to poor self-rated health and low quality-of-life?2019In: Health and Quality of Life Outcomes, ISSN 1477-7525, E-ISSN 1477-7525, Vol. 17, article id 33Article in journal (Refereed)
    Abstract [en]

    Background

    Both high socioeconomic status (SES) and high physical activity (PA) are associated with better self-rated health (SRH) and higher quality-of-life (QoL).

    Aim

    To investigate whether high levels of PA may compensate for the association between low SES and subjective health outcomes in terms of poorer SRH and lower QoL.

    Method

    Data from a cross-sectional, population-based study (n = 5326) was utilized. Multiple logistic regression models were used to estimate odds ratios (OR) and 95% confidence intervals (95% CI) for the associations between indicators of SES (economic situation and educational level), SRH and QoL, as well as between the combination of SES and PA in relation to SRH and QoL.

    Result

    Participants with high PA and economic problems had approximately the same OR for good SRH as those with low PA and without economic problems (OR 1.75 [95% CI 1.20–2.54] and 1.81 [1.25–2.63] respectively). Participants with high PA and low education had higher odds for good SRH (OR 3.34 [2.96–5.34] compared to those with low PA and high education (OR 1.46 [0.89–2.39]).Those with high PA and economic problems had an OR of 2.09 [1.42–3.08], for high QoL, while the corresponding OR for those with low PA and without economic problems was 4.38 [2.89–6.63].

    Conclusion

    Physically active people with low SES, had the same or even better odds to report good SRH compared to those with low PA and high SES. For QoL the result was not as consistent. The findings highlight the potential for promotion of PA to reduce SES-based inequalities in SRH.

    Development and evaluation of the Communication over Language Barriers questionnaire (CoLB-q) in paediatric healthcare2018In: Patient Education and Counseling, ISSN 0738-3991, E-ISSN 1873-5134, Vol. 101, no 9, p. 1661-1668Article in journal (Refereed)
    Abstract [en]

    Objective: To develop a valid and reliable questionnaire addressing the experiences of healthcare personnel of communicating over language barriers and using interpreters in paediatric healthcare. Methods: A multiple- methods approach to develop and evaluate the questionnaire, including focus groups, cognitive interviews, a pilot test and test-retest. The methods were chosen in accordance with questionnaire development methodology to ensure validity and reliability. Results: The development procedure showed that the issues identified were highly relevant to paediatric healthcare personnel and resulted in a valid and reliable Communication over Language Barriers questionnaire (CoLB-q) with 27 questions. Conclusion: The CoLB-q is perceived as relevant, important and easy to respond to by respondents and has satisfactory validity and reliability.amp; nbsp; Practice implications: The CoLB-q can be used to map how healthcare personnel overcome language barriers through communication tools and to identify problems encountered in paediatric healthcare. Furthermore, the transparently described process could be used as a guide for developing similar questionnaires. (C) 2018 The Authors. Published by Elsevier B.V.

    Electronic data capture on athletes pre-participation health and in-competition injury and illness at major sports championships: An extended usability study in Athletics2018In: Health Informatics Journal, ISSN 1460-4582, E-ISSN 1741-2811, Vol. 24, no 2, p. 136-145Article in journal (Refereed)
    Abstract [en]

    This study set out to identify factors critical for the usability of electronic data collection in association with championships in individual sports. A qualitative analysis of electronic data collection system usability for collection of data on pre-participation health from athletes and in-competition injury and illness from team physicians was performed during the 2013 European Athletics Indoor Championships. A total of 15 athletes and team physicians participated. Athletes were found to experience few problems interacting with the electronic data collection system, but reported concerns about having to reflect on injury and illness before competitions and the medical terminology used. Team physicians encountered problems when first navigating through the module for clinical reporting, but they were not subjected to motivational problems. We conclude that athletes motivation to self-report health data and the design of the human-computer interface for team physicians are key issues for the usability of electronic data collection systems in association with championships in individual sports.

    Information is the key to successful participation for patients receiving surgery for upper gastrointestinal cancer2019In: European Journal of Cancer Care, ISSN 0961-5423, E-ISSN 1365-2354, no 2, article id e12959Article in journal (Refereed)
    Abstract [en]

    Fast-track programmes are aimed at improving perioperative care. The purpose of this study was to identify and explore patient participation among patients who had surgery for liver, bile duct or pancreatic cancer and followed a fast-track programme. A total of 116 questionnaires to investigate patient participation were analysed. Information was important for the patients, as was having the opportunity to ask questions and express personal views. The results showed differences by sex; men responded to a greater extent that they did not want to make decisions as a patient (p = 0.044) and that they had been motivated to take more responsibility for their future health (p = 0.011). Patients with pancreatic cancer discussed treatment goals with doctors to a greater extent than did patients with liver cancer (p = 0.041). Half of the patients perceived that they had not been involved in their care planning after discharge but had a desired to be involved. This seems to be an important point to improve in future care, and also that professionals should be aware of patients' needs for information and participation, especially at discharge.

    Development of a self-care questionnaire for clinical assessment of self-care in patients with inflammatory bowel disease: A psychometric evaluation2019In: International Journal of Nursing Studies, ISSN 0020-7489, E-ISSN 1873-491X, Vol. 89Article in journal (Refereed)
    Abstract [en]

    Background

    Patients with inflammatory bowel disease have lifelong needs to learn how to manage their symptoms and life situation. The range of actions that patients take in order to manage daily life and maintain health is referred to as self-care. Assessment of self-care in patients with inflammatory bowel disease could allow targeted support and education by health careprofessionals. There are no existing measures assessing self-care in patients with inflammatory bowel disease.

    Objectives

    The aim was to develop and evaluate the self-care questionnaire for assessment of self-care among patients with inflammatory bowel disease.

    Methods

    Qualitative and quantitative methods were used to develop the inflammatory bowel disease self-care questionnaire. The development and evaluation process was performed in three phases: (1) item generation based on interviews with patients with inflammatory bowel disease (n = 20), (2) content validation in a panel of experts (n = 6) and patients (n = 100) assessed with the content validity index, cognitive interviews and quantifying and ranking the items to determine the usability of the questionnaire, and (3) final evaluation through a pilot study (n = 93) with test-retest evaluation (n = 50). An expert review group of three nurses and one physician continuously discussed the result during the development process.

    Results

    A total of 91 patients with Crohn's disease and 102 with ulcerative colitis participated. The final self-care questionnaire consists of 22 items. Assessment of content validity indicated that the items were adequate and easy to understand. Test-retest reliability was confirmed with intraclass correlations above 0.6 after a three week interval, for all items except one.

    Conclusion

    An inflammatory bowel disease-specific self-care questionnaire was developed using structured methods. The evaluation indicated good validity and reliability. The questionnaire may be a useful tool to assess the ability of patients with inflammatory bowel disease to perform routine self-care.

    A Text Message-Based Intervention Targeting Alcohol Consumption Among University Students: User Satisfaction and Acceptability Study.2018In: JMIR Human Factors, E-ISSN 2292-9495, Vol. 5, no 3, article id e23Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Heavy consumption of alcohol among university students is a global problem, with excessive drinking being the social norm. Students can be a difficult target group to reach, and only a minority seek alcohol-related support. It is important to develop interventions that can reach university students in a way that does not further stretch the resources of the health services. Text messaging (short message service, SMS)-based interventions can enable continuous, real-time, cost-effective, brief support in a real-world setting, but there is a limited amount of evidence for effective interventions on alcohol consumption among young people based on text messaging. To address this, a text messaging-based alcohol consumption intervention, the Amadeus 3 intervention, was developed.

    OBJECTIVE: This study explored self-reported changes in drinking habits in an intervention group and a control group. Additionally, user satisfaction among the intervention group and the experience of being allocated to a control group were explored.

    METHODS: Students allocated to the intervention group (n=460) were asked about their drinking habits and offered the opportunity to give their opinion on the structure and content of the intervention. Students in the control group (n=436) were asked about their drinking habits and their experience in being allocated to the control group. Participants received an email containing an electronic link to a short questionnaire. Descriptive analyses of the distribution of the responses to the 12 questions for the intervention group and 5 questions for the control group were performed.

    RESULTS: The response rate for the user feedback questionnaire of the intervention group was 38% (176/460) and of the control group was 30% (129/436). The variation in the content of the text messages from facts to motivational and practical advice was appreciated by 77% (135/176) participants, and 55% (97/176) found the number of messages per week to be adequate. Overall, 81% (142/176) participants stated that they had read all or nearly all the messages, and 52% (91/176) participants stated that they were drinking less, and increased awareness regarding negative consequences was expressed as the main reason for reduced alcohol consumption. Among the participants in the control group, 40% (52/129) stated that it did not matter that they had to wait for access to the intervention. Regarding actions taken while waiting for access, 48% (62/129) participants claimed that they continued to drink as before, whereas 35% (45/129) tried to reduce their consumption without any support.

    CONCLUSIONS: Although the main randomized controlled trial was not able to detect a statistically significant effect of the intervention, most participants in this qualitative follow-up study stated that participation in the study helped them reflect upon their consumption, leading to altered drinking habits and reduced alcohol consumption.

    The Top 100 Articles in the Medical Informatics: a Bibliometric Analysis2017In: Journal of medical systems, ISSN 0148-5598, E-ISSN 1573-689X, Vol. 41, no 10, article id 150Article in journal (Refereed)
    Abstract [en]

    The number of citations that a research paper receives can be used as a measure of its scientific impact. The objective of this study was to identify and to examine the characteristics of top 100 cited articles in the field of Medical Informatics based on data acquired from the Thomson Reuters Web of Science (WOS) in October, 2016. The data was collected using two procedures: first we included articles published in the 24 journals listed in the "Medical Informatics" category; second, we retrieved articles using the key words: "informatics", "medical informatics", "biomedical informatics", "clinical informatics" and "health informatics". After removing duplicate records, articles were ranked by the number of citations they received. When the 100 top cited articles had been identified, we collected the following information for each record: all WOS database citations, year of publication, journal, author names, authors affiliation, country of origin and topics indexed for each record. Citations for the top 100 articles ranged from 346 to 7875, and citations per year ranged from 11.12 to 525. The majority of articles were published in the 2000s (n=43) and 1990s (n=38). Articles were published across 10 journals, most commonly Statistics in medicine (n=71) and Medical decision making (n=28). The articles had an average of 2.47 authors. Statistics and biostatistics modeling was the most common topic (n=71), followed by artificial intelligence (n=12), and medical errors (n=3), other topics included data mining, diagnosis, bioinformatics, information retrieval, and medical imaging. Our bibliometric analysis illustrated a historical perspective on the progress of scientific research on Medical Informatics. Moreover, the findings of the current study provide an insight on the frequency of citations for top cited articles published in Medical Informatics as well as quality of the works, journals, and the trends steering Medical Informatics.

    Incidence of adverse events in Sweden during 2013-2016: a cohort study describing the implementation of a national trigger tool2018In: BMJ Open, E-ISSN 2044-6055, Vol. 8, no 3, article id e020833Article in journal (Refereed)
    Abstract [en]

    Objectives To describe the implementation of a trigger tool in Sweden and present the national incidence of adverse events (AEs) over a 4-year period during which an ongoing national patient safety initiative was terminated. Design Cohort study using retrospective record review based on a trigger tool methodology. Setting and participants Patients amp;gt;= 18 years admitted to all somatic acute care hospitals in Sweden from 2013 to 2016 were randomised into the study. Primary and secondary outcome measures Primary outcome rneasure was the incidence of AEs, and secondary measures were type of injury, severity of harm, preventability of AEs, estimated healthcare cost of AEs and incidence of AEs in patients cared for in another type of unit than the one specialised for their medical needs (off-site). Results In a review of 64 917 admissions, the average AE rates in 2014 (11.6%), 2015(10.9%) and 2016 (11.4%) were significantly lower than in 2013 (13.1 %). The decrease in the AE rates was seen in different age groups, in both genders and for preventable and non-preventable AEs. The decrease comprised only the least severe AEs. The types of AEs that decreased were hospital-acquired infections, urinary bladder distention and compromised vital signs. Patients cared for off-site had 84% more preventable AEs than patients cared for in the appropriate units. The cost of increased length of stay associated with preventable AEs corresponded to 13%-14% of the total cost of somatic hospital care in Sweden. Conclusions The rate of AEs in Swedish somatic hospitals has decreased from 2013 to 2016. Retrospective record review can be used to monitor patient safety over time, to assess the effects of national patient safety interventions and analyse challenges to patient safety such as the increasing care of patients off-site. It was found that the economic burden of preventable AEs is high.

    The Swedish RAND-36 Health Survey - reliability and responsiveness assessed in patient populations using Svensson's method for paired ordinal data.2018In: Journal of patient-reported outcomes, ISSN 2509-8020, Vol. 2, no 4Article in journal (Refereed)
    Abstract [en]

    Background: The Short Form 36-Item Survey is one of the most commonly used instruments for assessing health-related quality of life. Two identical versions of the original instrument are currently available: the public domain, license free RAND-36 and the commercial SF-36.RAND-36 is not available in Swedish. The purpose of this study was threefold: to translate and culturally adapt the RAND-36 into Swedish; to evaluate its reliability and responsiveness using Svensson's method for paired ordered categorical data; and to assess the usability of an electronic version of the questionnaire.The translation process included forward and backward translations and reconciliation. Test-retest reliability was examined during a period of two-weeks in 84 patients undergoing dialysis for chronic kidney disease. Responsiveness was examined in 97 patients before and 2 months after a cardiac rehabilitation program. Usability tests and cognitive debriefing of the electronic questionnaire were carried out with 18 patients.

    Results: The Swedish translation of the RAND-36 was conceptually equivalent to the English version. Test-retest reliability was supported by non-significant relative position (RP) values among dialysis patients for all RAND-36 subscales (range - 0.02 to 0.10; all confidence intervals (CI) included zero). Responsiveness was demonstrated by significant improvements in RP values among cardiac rehabilitation patients for all subscales (range 0.22-0.36; lower limits of all CI > 0.1) except two subscales (General health, RP -0.02; CI -0.13 to 0.10; and Role functioning/emotional, RP 0.03; CI -0.09 to 0.16). In cardiac rehabilitation patients, sizable individual variation (RV > 0.2) was also shown for the Pain, Energy/fatigue and Social functioning subscales.The electronic version of RAND-36 was found easy and intuitive to use.

    Conclusions: Our results provide evidence supporting the reliability and responsiveness of the newly translated Swedish RAND-36 and the user-friendliness of the electronic version. Svensson's method for paired ordinal data was able to characterize not only the direction and size of differences among the patients' responses at different time points but also variations in response patterns within groups. The method is therefore, besides being suitable for ordinal data, also an important and novel tool for gaining insights into patients' response patterns to treatment or interventions, thus informing individualized care.

    Translating and culturally adapting the shortened version of the Hospital Ethical Climate Survey (HECS-S) - retaining or modifying validated instruments2018In: BMC Medical Ethics, ISSN 1472-6939, E-ISSN 1472-6939, Vol. 19, article id 35Article in journal (Refereed)
    Abstract [en]

    Background: The Hospital Ethical Climate Survey (HECS) was developed in the USA and later shortened (HECS-S). HECS has previously been translated into Swedish and the aim of this study was to describe a process of translating and culturally adapting HECS-S and to develop a Swedish multi-professional version, relevant for paediatrics. Another aim was to describe decisions about retaining versus modifying the questionnaire in order to keep the Swedish version as close as possible to the original while achieving a good functional level and trustworthiness. Methods: In HECS-S, the respondents are asked to indicate the veracity of statements. In HECS and HECS-S the labels of the scale range from almost never true to almost always true; while the Swedish HECS labels range from never to always. The procedure of translating and culturally adapting the Swedish version followed the scientific structure of guidelines. Three focus group interviews and three cognitive interviews were conducted with healthcare professionals. Furthermore, descriptive data were used from a previous study with healthcare professionals (n = 89), employing a modified Swedish HECS. Decisions on retaining or modifying items were made in a review group. Results: The Swedish HECS-S consists of 21 items including all 14 items from HECS-S and items added to develop a multi-professional version, relevant for paediatrics. The descriptive data showed that few respondents selected never and always. To obtain a more even distribution of responses and keep Swedish HECS-S close to HECS-S, the original labels were retained. Linguistic adjustments were made to retain the intended meaning of the original items. The word respect was used in HECS-S with two different meanings and was replaced in one of these because participants were concerned that respecting patients wishes implied always complying with them. Conclusions: The process of developing a Swedish HECS-S included decisions on whether to retain or modify. Only minor adjustments were needed to achieve a good functional level and trustworthiness although some items needed to be added. Adjustments made could be used to also improve the English HECS-S. The results shed further light on the need to continuously evaluate even validated instruments and adapt them before use.

    Strategies and factors associated with preparing for competing in the heat: a cohort study at the 2015 IAAF World Athletics Championships2017In: British Journal of Sports Medicine, ISSN 0306-3674, E-ISSN 1473-0480, Vol. 51, no 4, p. 264-271Article in journal (Refereed)
    Abstract [en]

    Purpose Assess exertional heat illness (EHI) history and preparedness in athletes competing in a World Athletics Championships under hot/humid conditions and identify the factors associated with preparedness strategies. Methods Of the 207 registered national teams invited to participate in the study, 50 (24%) accepted. The 957 athletes (49% of all 1965 registered) in these teams were invited to complete a precompetition questionnaire evaluating EHI history, heat stress prevention (heat acclimatisation, precooling and hydration) and recovery. Responses from 307 (32%) athletes were separated in field events, sprints, middle-distance and long-distance running, and decathlon/heptathlon for analysis. Results 48% of athletes had previously experienced EHI symptoms and 8.5% had been diagnosed with EHI. 15% heat acclimatised (similar to 20 days) before the championships. 52% had a precooling strategy, ice slurry ingestion (24%) being the most prevalent and women using it more frequently than men (p=0.005). 96% of athletes had a fluid consumption strategy, which differed between event categories (pamp;lt;0.001). The most common volumes planned on being consumed were 0.5-1 L (27.2%) and amp;gt;= 2 L (21.8%), water being the most frequent. 89% of athletes planned on using at least one recovery strategy. Female sex (p=0.024) and a previous EHI diagnosis increased the likelihood of using all 3 prevention strategies (pamp;lt;0.001). Conclusions At a World Championships with expected hot/humid conditions, less than one-fifth of athletes heat acclimatised, half had a precooling strategy and almost all a hydration plan. Women, and especially athletes with an EHI history, were more predisposed to use a complete heat stress prevention strategy. More information regarding heat acclimatisation should be provided to protect athlete health and optimise performance at major athletics competitions in the heat.

    The quality of care questionnaire: development of a valid measure for persons with inflammatory bowel disease2018In: Scandinavian Journal of Gastroenterology, ISSN 0036-5521, E-ISSN 1502-7708, Vol. 53, no 9, p. 1043-1050Article in journal (Refereed)
    Abstract [en]

    Background and aims: Quality of care is important in lifelong illnesses such as inflammatory bowel disease (IBD). Valid, reliable and short questionnaires to measure quality of care among persons with IBD are needed. The aim of this study was to develop a patient-derived questionnaire measuring quality of care in persons with IBD.Methods and results: The development of the questionnaire The Quality of Care -Questionnaire (QoC-Q) was based on a literature review of studies measuring quality of care, and the results of two qualitative studies aiming to identify the knowledge need and perception of health care among persons with IBD. Further development and evaluation was done by focus groups, individual testing and cognitive interviews with persons with IBD, as well as evaluation by a group of professionals. After the development, the questionnaire was tested for validity and test-retest reliability in 294 persons with IBD.Conclusions: The QoC-Q is showing promising validity and reliability for measuring the subjective perception of quality of care. Further testing in clinical practice is suggested to assess if the QoC-Q can be used to evaluate care and areas of improvement in health care for persons living with IBD.

    A Systematic Review of the Technology Acceptance Model in Health Informatics2018In: Applied Clinical Informatics, ISSN 1869-0327, Vol. 9, no 3, p. 604-634Article in journal (Refereed)
    Abstract [en]

    Background One common model utilized to understand clinical staff and patients technology adoption is the technology acceptance model (TAM). Objective This article reviews published research on TAM use in health information systems development and implementation with regard to application areas and model extensions after its initial introduction. Method An electronic literature search supplemented by citation searching was conducted on February 2017 of the Web of Science, PubMed, and Scopus databases, yielding a total of 492 references. Upon eliminating duplicates and applying inclusion and exclusion criteria, 134 articles were retained. These articles were appraised and divided into three categories according to research topic: studies using the original TAM, studies using an extended TAM, and acceptance model comparisons including the TAM. Results The review identified three main information and communication technology (ICT) application areas for the TAM in health services: telemedicine, electronic health records, and mobile applications. The original TAM was found to have been extended to fit dynamic health service environments by integration of components from theoretical frameworks such as the theory of planned behavior and unified theory of acceptance and use of technology, as well as by adding variables in specific contextual settings. These variables frequently reflected the concepts subjective norm and self-efficacy, but also compatibility, experience, training, anxiety, habit, and facilitators were considered. Conclusion Telemedicine applications were between 1999 and 2017, the ICT application area most frequently studied using the TAM, implying that acceptance of this technology was a major challenge when exploiting ICT to develop health service organizations during this period. A majority of the reviewed articles reported extensions of the original TAM, suggesting that no optimal TAM version for use in health services has been established. Although the review results indicate a continuous progress, there are still areas that can be expanded and improved to increase the predictive performance of the TAM.

    What Is Performance? A Scoping Review of Performance Outcomes as Study Endpoints in Athletics2019In: SPORTS, ISSN 2075-4663, Vol. 7, no 3, article id 66Article, review/survey (Refereed)
    Abstract [en]

    Purpose: This review set out to summarise, define, and provide future direction towards the use of performance outcome measures as endpoints in research performed at international benchmark events in athletics. Methods: Scoping review methodology was applied through a search of the PubMed and Sports Discus databases and a systematic article selection procedure. Articles that met the inclusion criteria underwent triage for further quantitative and qualitative analysis. A concept chart was generated to describe the methods by which performance had been measured and introduce descriptive labels for theoretical and practical application. Results: None of 2972 articles primarily identified from the database search met the triage standards for quantitative data extraction. Eleven articles were included in a qualitative analysis. The analysis identified the common methods by which performance has been measured, reported and analysed. The resulting concept chart collates labels from the qualitative analysis (categories, themes, and constructs) with sports practice labels (performance metrics, framework, and analysis). Conclusions: The state of knowledge concerning methods to employ performance metrics as endpoints in studies performed at major competitions in athletics has been summarised. Constructing a methodology that combines the performance metric variables (continuous and ordinal) that are currently utilised as endpoints remains a challenge.

    Young athletes health knowledge system: Qualitative analysis of health learning processes in adolescent sportspersons2018In: Scandinavian Journal of Medicine and Science in Sports, ISSN 0905-7188, E-ISSN 1600-0838, Vol. 28, no 3, p. 1272-1280Article in journal (Refereed)
    Abstract [en]

    Recognized side effects on health associated with sports participation in youth include overtraining, doping, and exposure to harassment and violence. Many of these effects originate in contexts where young athletes are beginning to make decisions about their sports practices on their own. This study sets out to explore knowledge and reasoning about health among adolescent athletes and to describe how health knowledge management structures are associated with different social systems. Qualitative data were collected from focus groups involving 65 young Swedish athletes aged 16-17years. The participants knowledge and reasoning about health were examined using a deductive thematic analysis, categories from Blooms taxonomy of educational objectives, and Luhmanns social systems theory. The meaning of health was found to have a dynamic character for the young athletes, associated with constantly striving to satisfy immediate needs and fulfill short-time life goals. The athletes thinking about health was associated with a pragmatic health-as-a-resource perspective, characterized by group self-comparisons, rapid cognitive processing, and opportunistic substitutions. They expressed a particular interest in experiential learning and personally relevant procedural knowledge, and they perceived that their factual knowledge about health was saturated. The results of this study add emphasis to the importance of involving adolescent sportspersons in the development of health education programs and contextualizing the programs to the athletes specific age and social environment.

    mHealth Self-Report Monitoring in Competitive Middle- and Long-Distance Runners: Qualitative Study of Long-Term Use Intentions Using the Technology Acceptance Model2018In: JMIR mhealth and uhealth, E-ISSN 2291-5222, Vol. 6, no 8, article id e10270Article in journal (Refereed)
    Abstract [en]

    Background: International middle- and long-distance running competitions attract millions of spectators in association with city races, world championships, and Olympic Games. It is therefore a major concern that ill health and pain, as a result of sports overuse, lead to numerous hours of lost training and decreased performance in competitive runners. Despite its potential for sustenance of performance, approval of mHealth self-report monitoring (mHSM) in this group of athletes has not been investigated. Objective: The objective of our study was to explore individual and situational factors associated with the acceptance of long-term mHSM in competitive runners. Methods: The study used qualitative research methods with the Technology Acceptance Model as the theoretical foundation. The study population included 20 middle- and long-distance runners competing at national and international levels. Two mHSM apps asking for health and training data from track and marathon runners were created on a platform for web survey development (Briteback AB). Data collection for the technology acceptance analysis was performed via personal interviews before and after a 6-week monitoring period. Preuse interviews investigated experience and knowledge of mHealth monitoring and thoughts on benefits and possible side effects. The postuse interviews addressed usability and usefulness, attitudes toward nonfunctional issues, and intentions to adhere to long-term monitoring. In addition, the runners trustworthiness when providing mHSM data was discussed. The interview data were investigated using a deductive thematic analysis. Results: The mHSM apps were considered technically easy to use. Although the runners read the instructions and entered data effortlessly, some still perceived mHSM as problematic. Concerns were raised about the selection of items for monitoring (eg, recording training load as running distance or time) and about interpretation of concepts (eg, whether subjective well should encompass only the running context or daily living on the whole). Usefulness of specific mHSM apps was consequently not appraised on the same bases in different subcategories of runners. Regarding nonfunctional issues, the runners competing at the international level requested detailed control over who in their sports club and national federation should be allowed access to their data; the less competitive runners had no such issues. Notwithstanding, the runners were willing to adhere to long-term mHSM, provided the technology was adjusted to their personal routines and the output was perceived as contributing to running performance. Conclusions: Adoption of mHSM by competitive runners requires clear definitions of monitoring purpose and populations, repeated in practice tests of monitoring items and terminology, and meticulousness regarding data-sharing routines. Further naturalistic studies of mHSM use in routine sports practice settings are needed with nonfunctional ethical and legal issues included in the evaluation designs.

    Mobile phone applications to overcome malnutrition among preschoolers: a systematic review2019In: BMC Medical Informatics and Decision Making, E-ISSN 1472-6947, Vol. 19, article id 83Article, review/survey (Refereed)
    Abstract [en]

    BackgroundMalnutrition is one of the most important reasons for child mortality in developing countries, especially during the first 5years of life. We set out to systematically review evaluations of interventions that use mobile phone applications to overcome malnutrition among preschoolers.MethodsThe review was conducted and reported according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses: the PRISMA statement. To be eligible, the study had to have evaluated mobile phone interventions to increase nutrition knowledge or enhance behavior related to nutrition in order to cope with malnutrition (under nutrition or overweight) in preschoolers. Articles addressing other research topics, older children or adults, review papers, theoretical and conceptual articles, editorials, and letters were excluded. The PubMed, Web of Science and Scopus databases covering both medical and technical literature were searched for studies addressing preschoolers malnutrition using mobile technology.ResultsSeven articles were identified that fulfilled the review criteria. The studies reported in the main positive signals concerning the acceptance of mobile phone based nutritional interventions addressing preschoolers. Important infrastructural and technical limitations to implement mHealth in low and middle income countries (LMICs) were also communicated, ranging from low network capacity and low access to mobile phones to specific technical barriers. Only one study was identified evaluating primary anthropometric outcomes.ConclusionsThe review findings indicated a need for more controlled evaluations using anthropometric primary endpoints and put relevance to the suggestion that cooperation between government organizations, academia, and industry is necessary to provide sufficient infrastructure support for mHealth use against malnutrition in LMICs.

    Abstract [sv]

    Hälsoinriktning med interprofessionellt och problembaserat lärande harlång tradition vid den medicinska fakulteten (tidigare Hälsouniversitetet) iLinköpings universitet. Denna ämnesinriktning, pedagogik och förhållningssättgenom syrar också det interprofessionella masterprogram som startade2008. Detta har utgångspunkt i behovet av att utveckla en mer hälsofrämjandehälso- och sjukvård för att möta framtidens behov samt utvecklakvalitet och hälsoresultat. Teori och metod för hälsofrämjande, preventionoch förbättrings kunskap är därför centrala delar i alla professionsinriktningarpå masternivå och inte enbart kunskapsområden för folkhälsovetaren. Dettainnebär att alla studenter får en ämnesspecifi k examen med ett folkhälsovetenskapligtperspektiv, och studenterna med inriktning folkhälsovetenskapen fördjupning av dessa kunskaper. Alumni bekräftar att de fått verktyg föratt utveckla kvalitet och hälsoorientering av hälso- och sjukvården som detidigare saknat.

    Evaluation of Nowcasting for Detecting and Predicting Local Influenza Epidemics, Sweden, 2009-20142018In: Emerging Infectious Diseases, ISSN 1080-6040, E-ISSN 1080-6059, Vol. 24, no 10, p. 1868-1873Article in journal (Refereed)
    Abstract [en]

    The growing availability of big data in healthcare and public health opens possibilities for infectious disease control in local settings. We prospectively evaluated a method for integrated local detection and prediction (nowcasting) of influenza epidemics over 5 years, using the total population in Ostergotland County, Sweden. We used routine health information system data on influenza-diagnosis cases and syndromic telenursing data for July 2009-June 2014 to evaluate epidemic detection, peak-timing prediction, and peak-intensity prediction. Detection performance was satisfactory throughout the period, except for the 2011-12 influenza A(H3N2) season, which followed a season with influenza B and pandemic influenza A(H1N1) pdm09 virus activity. Peak-timing prediction performance was satisfactory for the 4 influenza seasons but not the pandemic. Peak-intensity levels were correctly categorized for the pandemic and 2 of 4 influenza seasons. We recommend using versions of this method modified with regard to local use context for further evaluations using standard methods.

    Integrated Detection and Prediction of Influenza Activity for Real-Time Surveillance: Algorithm Design2017In: Journal of Medical Internet Research, ISSN 1438-8871, E-ISSN 1438-8871, Vol. 19, no 6, article id e211Article in journal (Refereed)
    Abstract [en]

    Background: Influenza is a viral respiratory disease capable of causing epidemics that represent a threat to communities worldwide. The rapidly growing availability of electronic "big data" from diagnostic and prediagnostic sources in health care and public health settings permits advance of a new generation of methods for local detection and prediction of winter influenza seasons and influenza pandemics. Objective: The aim of this study was to present a method for integrated detection and prediction of influenza virus activity in local settings using electronically available surveillance data and to evaluate its performance by retrospective application on authentic data from a Swedish county. Methods: An integrated detection and prediction method was formally defined based on a design rationale for influenza detection and prediction methods adapted for local surveillance. The novel method was retrospectively applied on data from the winter influenza season 2008-09 in a Swedish county (population 445,000). Outcome data represented individuals who met a clinical case definition for influenza (based on International Classification of Diseases version 10 [ICD-10] codes) from an electronic health data repository. Information from calls to a telenursing service in the county was used as syndromic data source. Results: The novel integrated detection and prediction method is based on nonmechanistic statistical models and is designed for integration in local health information systems. The method is divided into separate modules for detection and prediction of local influenza virus activity. The function of the detection module is to alert for an upcoming period of increased load of influenza cases on local health care (using influenza-diagnosis data), whereas the function of the prediction module is to predict the timing of the activity peak (using syndromic data) and its intensity (using influenza-diagnosis data). For detection modeling, exponential regression was used based on the assumption that the beginning of a winter influenza season has an exponential growth of infected individuals. For prediction modeling, linear regression was applied on 7-day periods at the time in order to find the peak timing, whereas a derivate of a normal distribution density function was used to find the peak intensity. We found that the integrated detection and prediction method detected the 2008-09 winter influenza season on its starting day (optimal timeliness 0 days), whereas the predicted peak was estimated to occur 7 days ahead of the factual peak and the predicted peak intensity was estimated to be 26% lower than the factual intensity (6.3 compared with 8.5 influenza-diagnosis cases/100,000). Conclusions: Our detection and prediction method is one of the first integrated methods specifically designed for local application on influenza data electronically available for surveillance. The performance of the method in a retrospective study indicates that further prospective evaluations of the methods are justified.

    Influenza detection and prediction algorithms: comparative accuracy trial in Ostergotland county, Sweden, 2008-20122017In: Epidemiology and Infection, ISSN 0950-2688, E-ISSN 1469-4409, Vol. 145, no 10, p. 2166-2175Article in journal (Refereed)
    Abstract [en]

    Methods for the detection of influenza epidemics and prediction of their progress have seldom been comparatively evaluated using prospective designs. This study aimed to perform a prospective comparative trial of algorithms for the detection and prediction of increased local influenza activity. Data on clinical influenza diagnoses recorded by physicians and syndromic data from a telenursing service were used. Five detection and three prediction algorithms previously evaluated in public health settings were calibrated and then evaluated over 3 years. When applied on diagnostic data, only detection using the Serfling regression method and prediction using the non-adaptive log-linear regression method showed acceptable performances during winter influenza seasons. For the syndromic data, none of the detection algorithms displayed a satisfactory performance, while non-adaptive log-linear regression was the best performing prediction method. We conclude that evidence was found for that available algorithms for influenza detection and prediction display satisfactory performance when applied on local diagnostic data during winter influenza seasons. When applied on local syndromic data, the evaluated algorithms did not display consistent performance. Further evaluations and research on combination of methods of these types in public health information infrastructures for nowcasting (integrated detection and prediction) of influenza activity are warranted.

    Place-based social contact and mixing: a typology of generic meeting places of relevance for infectious disease transmission2017In: Epidemiology and Infection, ISSN 0950-2688, E-ISSN 1469-4409, Vol. 145, no 12, p. 2582-2593Article in journal (Refereed)
    Abstract [en]

    This study aims to develop a typology of generic meeting places based on social contact and mixing of relevance for infectious disease transmission. Data were collected by means of a contact diary survey conducted on a representative sample of the Swedish population. The typology is derived from a cluster analysis accounting for four dimensions associated with transmission risk: visit propensity and its characteristics in terms of duration, number of other persons present and likelihood of physical contact. In the analysis, we also study demographic, socio-economic and geographical differences in the propensity of visiting meeting places. The typology identifies the family venue, the fixed activity site, the family vehicle, the trading plaza and the social network hub as generic meeting places. The meeting place typology represents a spatially explicit account of social contact and mixing relevant to infectious disease modelling, where the social context of the outbreak can be highlighted in light of the actual infectious disease.

    Rationale for a Swedish cohort consortium2019In: Upsala Journal of Medical Sciences, ISSN 0300-9734, E-ISSN 2000-1967, Vol. 124, no 1, p. 21-28Article in journal (Refereed)
    Abstract [en]

    We herein outline the rationale for a Swedish cohort consortium, aiming to facilitate greater use of Swedish cohorts for world-class research. Coordination of all Swedish prospective population-based cohorts in a common infrastructure would enable more precise research findings and facilitate research on rare exposures and outcomes, leading to better utilization of study participants data, better return of funders investments, and higher benefit to patients and populations. We motivate the proposed infrastructure partly by lessons learned from a pilot study encompassing data from 21 cohorts. We envisage a standing Swedish cohort consortium that would drive development of epidemiological research methods and strengthen the Swedish as well as international epidemiological competence, community, and competitiveness.

    Associations between recreational runners anti-inflammatory drug use, coping strategies, and time loss due to injury and illness during preparations for a marathon event2018In: Journal of Sports Medicine and Physical Fitness, ISSN 0022-4707, E-ISSN 1827-1928, Vol. 58, no 12, p. 1839-1843Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Due to the dominance of overuse injuries among runners, knowledge of how use of non-steroidal anti-inflammatory drugs (NSAIDs) and behavioral factors contribute to injury events is important. The aim of this study was to explore recreational marathon runners strategies for coping with injury and illness, including use of drugs for control of pain and inflammation, and to investigate whether these strategies were associated with the 1-year prevalence of time-loss injury and illness. METHODS: An online questionnaire was used for data collection in this cross-sectional study. The population consisted of runners who had registered for a marathon (N.=341). Strategies used to understand and manage perceptions of injury and illness were measured with the Brief COPE instrument and the use of NSAIDs was investigated. RESULTS: Complete survey data were provided by 161 runners (47%). 42% reported NSAID use. A notable injury in the past year was reported by 43%, and 19% reported having had a time-loss illness episode. Runners who reported NSAID use in the past year reported significantly fewer time-loss injuries (P=0.003). Time loss due to illness only showed a negative correlation with using emotional support for coping (P=0.010) and a positive correlation with self-blame (P=0.039). CONCLUSIONS: Runners stating NSAID use reported fewer time-loss running injuries than non-NSAID users. Time loss due to illness showed different correlates with NSAID use and coping strategies than time loss due to injury, i.e. no association with drug use, less use of emotional support for coping and more use of self-blame.

    Symptomatic Achilles Tendons are Thicker than Asymptomatic Tendons on Ultrasound Examination in Recreational Long-Distance Runners2019In: SPORTS, ISSN 2075-4663, Vol. 7, no 12, article id 245Article in journal (Refereed)
    Abstract [en]

    There is a need for clinical indicators that can be used to guide the treatment of Achilles tendon complaints in recreational runners. Diagnostic ultrasound has recently been introduced for clinical decision support in tendon pain management. The aim of this study was to determine whether tendon thickness and morphological changes in the Achilles tendon detected in ultrasound examinations are associated with local symptoms in middle-age recreational long-distance runners. Forty-two Achilles tendons (21 middle-aged runners) were investigated by ultrasound examination measuring tendon thickness and a morphology score indicating tendinosis. The Generalized Estimating Equations method was applied in multiple models of factors associated with reporting a symptomatic tendon. Eleven symptomatic and 31 asymptomatic Achilles tendons were recorded. In the multiple model that used tendon thickness measured 30 mm proximal to the distal insertion, an association was found between thickness and reporting a symptomatic tendon (p amp;lt; 0.001; OR 12.9; 95% CI 3.1 to 53.2). A qualitative morphology score was not found to be significantly associated with reporting a symptomatic tendon (p = 0.10). We conclude that symptomatic Achilles tendons were thicker than asymptomatic tendons on ultrasound examination among recreational long-distance runners and that the importance of parallel morphological findings need to be further investigated in prospective studies.

    Reduced workforce participation 5 years prior to first Parkinsons disease sick-leave2018In: NPJ Parkinsons disease, ISSN 2373-8057, Vol. 4, article id 36Article in journal (Refereed)
    Abstract [en]

    The importance of understanding the prodromal phase of Parkinsons disease (PD) by systematic recording of prediagnostic symptoms and reductions in body functions has been highlighted. The aim of this study was to investigate whether persons later diagnosed with PD exhibit increased physician-certified sickness absence 1, 2, and 5 years prior to a first sick-leave episode attributed to PD. A case-control study was performed to analyze data from all nontrivial (exceeding 14 days) sick-leave episodes in Sweden between 2008 and 2014. The 537 incident PD sick-leave episodes were identified as PD sick-leave cases and compared to 537 sick-leave controls identified by matching age, sex, and date of the first day of the sick-leave episode. The total sickness absence and sickness absence due to musculoskeletal diagnoses were found to be increased among the PD sick-leave cases from 5 years prior to the first sick-leave episode ascribed to PD when compared to the controls. No differences between PD sick-leave cases and sick-leave controls were found with regard to mental and behavioral diagnoses. We conclude that the capacity to participate in working life is reduced already at the early prediagnostic stages of PD. This finding can be used as a basis for further research into the process of identifying individuals at risk for developing PD, particularly in combination with further investigation into biochemical, genetic, and imaging biomarkers.

    Injury Pain in Track and Field Athletes: Cross-Sectional Study of Mediating Factors2019In: SPORTS, ISSN 2075-4663, Vol. 7, no 5, article id 110Article in journal (Refereed)
    Abstract [en]

    This exploratory study aimed to investigate whether data from track and field athletes support a conceptual model where the perception of pain affects self-evaluated health directly, yet is also indirectly mediated through personal factors and external stressors. A cross-sectional study was performed among athletes (n = 278) competing at the highest national level in the sport. Data for the dependent and independent variables were collected using the EuroQol-5 dimensions (EQ-5D) standardized measure of health status, and the mediator variables were collected by the Body Consciousness Scale (BCS-HA), Perceived Motivational Climate in Sport Questionnaire (PMCSQ), Commitment to Exercise Scale (CtES), and Brief Cope survey instruments. Two hundred and twenty-five (81%) athletes provided complete data sets. A strong direct association (c = -16.49; p amp;lt; 0.001) was found between pain and self-estimated health, and a global mediation was found through the mediators (mediation effect (ME), -1.814, 90% confidence interval (CI), -3.414, -0.351). Specific mediation was observed for body competence (ME, -0.721; 90% CI, -2.028, -0.097) and private body consciousness (ME, -0.514; 90% CI, -1.761, -0.017). In conclusion, we found a negative association between perceived pain and self-evaluated health among competitive track and field athletes, and we found that a portion of the association was mediated through mediating factors. Under the assumption that the analyzed pain data primarily represented noxious pain, the conceptual model of the relationships between pain and self-estimated health among high-level track and field athletes was supported.

    Preparticipation predictors for championship injury and illness: cohort study at the Beijing 2015 International Association of Athletics Federations World Championships2017In: British Journal of Sports Medicine, ISSN 0306-3674, E-ISSN 1473-0480, Vol. 51, no 4, p. 272-+Article in journal (Refereed)
    Abstract [en]

    Objectives To determine preparticipation predictors of injury and illness at a major Athletics championship. Methods A cohort study design was used. Before the 2015 International Association of Athletics Federations World Championships in Athletics, all 207 registered national teams were approached about partaking in a study of preparticipation health; 50 teams accepted. The athletes (n=957) in the participating teams were invited to complete a preparticipation health questionnaire (PHQ). New injuries and illnesses that occurred at the championships were prospectively recorded. Logistic regression analyses were performed with simple and multiple models using any in-championship injury and in-championship illness as outcomes. Results The PHQ was completed by 307 (32.1%) of the invited athletes; 116 athletes (38.3%) reported an injury symptom during the month before the championships, while 40 athletes (13%) reported an illness symptom. 20 (6.5%) of the participating athletes sustained a health problem during the championships. Endurance athletes were almost 10-fold more likely to sustain an in-championship illness than speed/power athletes (OR, 9.88; 95% CI 1.20 to 81.31; p=0.033). Participants reporting a preparticipation gradual-onset injury symptom were three times more likely (OR, 3.09; 95% CI 1.08 to 8.79; p=0.035) and those reporting an illness symptom causing anxiety were fivefold more likely (OR, 5.56; 95% CI 1.34 to 23.15; p=0.018) to sustain an in-championship injury. Summary and conclusions Analyses of preparticipation predictors of injury and illness at a major Athletics championship suggest that endurance athletes require particular clinical attention. Preparticipation symptoms causing anxiety are interesting predictors for in-championship health problems.

    Lifetime history of sexual and physical abuse among competitive athletics (track and field) athletes: cross sectional study of associations with sports and non-sports injury2019In: British Journal of Sports Medicine, ISSN 0306-3674, E-ISSN 1473-0480, Vol. 53, no 22, p. 1412-1417Article in journal (Refereed)
    Abstract [en]

    Objective To examine associations between lifetime sexual and physical abuse, and the likelihood of injury within and outside sport in athletes involved in competitive athletics.

    Methods A cross sectional study was performed among the top 10 Swedish athletics athletes using 1 year prevalence of sports and non-sports injuries as the primary outcome measure. Associations with sociodemographic characteristics, lifetime abuse history and training load were investigated. Data were analysed using simple and multiple logistic regression models.

    Results 11% of 197 participating athletes reported lifetime sexual abuse; there was a higher proportion of women (16.2%) than men (4.3%) (P=0.005). 18% reported lifetime physical abuse; there was a higher proportion of men (22.8%) than women (14.3%) (P=0.050). For women, lifetime sexual abuse was associated with an increased likelihood of a non-sports injury (OR 8.78, CI 2.76 to 27.93; P<0.001). Among men, increased likelihood of a non-sports injury was associated with more frequent use of alcoholic beverages (OR 6.47, CI 1.49 to 28.07; P=0.013), while commencing athletics training at >13 years of age was associated with a lower likelihood of non-sports injury (OR 0.09, CI 0.01 to 0.81; P=0.032). Lifetime physical abuse was associated with a higher likelihood of sports injury in women (OR 12.37, CI 1.52 to 100.37; P=0.019). Among men, athletes with each parents with ≤12 years formal education had a lower likelihood of sustaining an injury during their sports practice (OR 0.37, CI 0.14 to 0.96; P=0.040).

    Conclusions Lifetime sexual and physical abuse were associated with an increased likelihood of injury among female athletes. Emotional factors should be included in the comprehension of injuries sustained by athletes.

    Value-Based Reimbursement in Collectively Financed Healthcare Requires Monitoring of Socioeconomic Patient Data to Maintain Equality in Service Provision2018In: Journal of general internal medicine, ISSN 0884-8734, E-ISSN 1525-1497, Vol. 33, no 12, p. 2240-2243Article in journal (Refereed)
    Abstract [en]

    Value-based purchasing is increasingly discussed in association with efforts to develop modern healthcare systems. These models are the most recent example of models derived from health economics research intended to reform collectively financed healthcare. Previous examples have ranged from creation of pseudo-markets to opening these markets for competition between publicly and privately owned enterprises. Most value-based purchasing models tend to ignore that health service provision in collectively financed settings is based on an insurance with political, social obligations attached that challenge the notion of free market and individualist premises which these models rest on. Central social issues related to healthcare in any modern complex society, such as inequality in service provision, can all too easily disappear in value-based reform efforts. Based on an analysis of Swedish policy development, we contend that management information systems need to be extended to allow routine monitoring of socioeconomic data when models such as value-based purchasing are introduced in collectively financed health services. The experiences from Sweden are important for health policy in Europe and other regions with collectively financed healthcare plans.

    Community-level football injury epidemiology: traumatic injuries treated at Swedish emergency medical facilities2018In: European Journal of Public Health, ISSN 1101-1262, E-ISSN 1464-360X, Vol. 28, no 1, p. 94-99Article in journal (Refereed)
    Abstract [en]

    Despite the popularity of the sport, few studies have investigated community-level football injury patterns. This study examines football injuries treated at emergency medical facilities using data from three Swedish counties. An open-cohort design was used based on residents aged 0-59 years in three Swedish counties (pop. 645 520). Data were collected from emergency medical facilities in the study counties between 1 January 2007 and 31 December 2010. Injury frequencies and proportions for age groups stratified by sex were calculated with 95% confidence intervals (95% CIs) and displayed per diagnostic group and body location. Each year, more than 1/200 person aged 0-59 years sustained at least one injury during football play that required emergency medical care. The highest injury incidence was observed among adolescent boys [2009 injuries per 100 000 population years (95% CI 1914-2108)] and adolescent girls [1413 injuries per 100 000 population years (95% CI 1333-1498)]. For female adolescents and adults, knee joint/ligament injury was the outstanding injury type (20% in ages 13-17 years and 34% in ages 18-29 years). For children aged 7-12 years, more than half of the treated injuries involved the upper extremity; fractures constituted about one-third of these injuries. One of every 200 residents aged 0-59 years in typical Swedish counties each year sustained a traumatic football injury that required treatment in emergency healthcare. Further research on community-level patterns of overuse syndromes sustained by participation in football play is warranted.

    Perceptions of Overuse Injury Among Swedish Ultramarathon and Marathon Runners: Cross-Sectional Study Based on the Illness Perception Questionnaire Revised (IPQ-R)2019In: Frontiers in Psychology, E-ISSN 1664-1078, Vol. 10, p. 1-11, article id 2406Article in journal (Refereed)
    Abstract [en]

    Background: Long-distance runners’ understandings of overuse injuries are not well known which decreases the possibilities for prevention. The common sense model (CSM) outlines that runners’ perceptions of a health problem can be described using the categories identity, consequence, timeline, personal control, and cause. The aim of this study was to use the CSM to investigate perceptions of overuse injury among long-distance runners with different exercise loads.

    Methods: The study used a cross-sectional design. An adapted version of the illness perception questionnaire revised (IPQ-R) derived from the CSM was used to investigate Swedish ultramarathon and marathon runners’ perceptions of overuse injuries. Cluster analysis was employed for categorizing runners into high and low exercise load categories. A Principal Component Analysis was thereafter used to group variables describing injury causes. Multiple logistic regression methods were finally applied using high exercise load as endpoint variable and CSM items representing perceptions of injury identity, consequence, timeline, personal control, and causes as explanatory variables.

    Results: Complete data sets were collected from 165/443 (37.2%) runners. The symptoms most commonly associated with overuse injury were pain (80.1% of the runners), stiff muscles (54.1%), and stiff joints (42.0%). Overuse injury was perceived to be characterized by the possibility of personal control (stated by 78.7% of the runners), treatability (70.4%), and that the injury context was comprehensible (69.3%). The main injury causes highlighted were runner biomechanics (stated by 78.3%), the runner’s personality (72.4%), and running surface biomechanics (70.0%). Among men, a belief in that personality contributes to overuse injury increased the likelihood of belonging to the high exercise load category [Odds ratio (OR) 2.10 (95% Confidence interval (95% CI) 1.38–3.19); P = 0.001], while beliefs in that running biomechanics [OR 0.56 (95% CI 0.37–0.85); P = 0.006) and mileage (OR 0.72 (95% CI 0.54–0.96); P = 0.026] causes injury decreased the likelihood. In women, a strong perception that overuse injuries can be controlled by medical interventions decreased the likelihood of high exercise load [OR 0.68 (95% CI 0.52–0.89); P = 0.005].

    Conclusion: This study indicates that recognition among long-distance runners of the association between own decisions in overuse injury causation is accentuated by increased exercise loads.

    Comprehensive study of thiopurine methyltransferase genotype, phenotype, and genotype-phenotype discrepancies in Sweden2019In: Biochemical Pharmacology, ISSN 0006-2952, E-ISSN 1356-1839, Vol. 164, p. 263-272Article in journal (Refereed)
    Abstract [en]

    Thiopurines are widely used in the treatment of leukemia and inflammatory bowel diseases. Thiopurine metabolism varies among individuals because of differences in the polymorphic enzyme thiopurine methyltransferase (TPMT, EC 2.1.1.67), and to avoid severe adverse reactions caused by incorrect dosing it is recommended that the patients TPMT status be determined before the start of thiopurine treatment. This study describes the concordance between genotyping for common TPMT alleles and phenotyping in a Swedish cohort of 12,663 patients sampled before or during thiopurine treatment. The concordance between TPMT genotype and enzyme activity was 94.5%. Compared to the genotype, the first measurement of TPMT enzyme activity was lower than expected for 4.6% of the patients. Sequencing of all coding regions of the TPMT gene in genotype/phenotype discrepant individuals led to the identification of rare and novel TPMT alleles. Fifteen individuals (0.1%) with rare or novel genotypes were identified, and three TPMT alleles (TPMT*42, *43, and *44) are characterized here for the first time. These 15 patients would not have been detected as carrying a deviating TPMT genotype if only genotyping of the most common TPMT variants had been performed. This study highlights the benefit of combining TPMT genotype and phenotype determination in routine testing. More accurate dose recommendations can be made, which might decrease the number of adverse reactions and treatment failures during thiopurine treatment.
