    Comparisons of automated blood pressures in a primary health care setting with self-measurements at the office and at home using the Omron i-C10 device2015Ingår i: Blood Pressure Monitoring, ISSN 1359-5237, E-ISSN 1473-5725, Vol. 20, nr 2, s. 98-103Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    OBJECTIVE: We aimed to compare blood pressure (BP) levels recorded using the semiautomatic oscillometric Omron i-C10 BP device in patients with or without hypertension in three different settings: (a) when used by a doctor or a nurse at the office (OBP); (b) when used for self-measurement by the patient at the office (SMOBP); and (c) when used for 7 consecutive days at home (HBP).

    MATERIALS AND METHODS: A total of 247 individuals were invited to participate, but 78 of these individuals declined and a further seven were excluded, leaving a final cohort of 162 participants.

    RESULTS: The mean OBP was higher than HBP (difference 8.1±14/3.1±8.8 mmHg, P<0.0001) and so was SMOBP compared with HBP (difference 7.0±13/4.2±7.3 mmHg, P<0.0001). Sixteen participants (9.9%) had at least 10 mmHg higher systolic SMOBP than OBP and 28 (17%) participants had at least 10 mmHg lower systolic SMOBP than OBP. Participants who were current smokers had a larger mean difference between systolic OBP and SMOBP than nonsmokers (OBP-SMOBP in smokers: 6.6±9.4 mmHg, OBP-SMOBP in nonsmokers: 0.5±9.2 mmHg, P=0.011 between groups).

    CONCLUSION: Self-measurement of BP in the office does not preclude an increase in BP when levels in the individual patients are compared with HBP using the same equipment. Thus, SMOBP with a semiautomatic device does not lead to a reduction in the white-coat effect in the same manner as fully automatic devices.This is an open-access article distributed under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives 3.0 License, where it is permissible to download and share the work provided it is properly cited.

    Legitimacy of work tasks, psychosocial work environment, and time utilization among primary care staff in Sweden2019Ingår i: Scandinavian Journal of Primary Health Care, ISSN 0281-3432, E-ISSN 1502-7724, s. 1-8Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective: Primary care staff faces a complex work environment including a heavy administrative work load and perceive some work tasks as illegitimate. This study aimed to elucidate associations between the perceived legitimacy of work tasks, the psychosocial work environment, and the utilization of work time among Swedish primary care staff.

    Design and setting: The study was designed as a multicenter study involving all staff categories, i.e. registered nurses, primary care physicians, care administrators, nurse assistants and allied professionals, at eleven primary care centers in Sweden.

    Subjects: Participants completed the Bern Illegitimate Tasks Scale and the Copenhagen Psychosocial Questionnaire. They also recorded time spent on all work tasks, day by day during two separate weeks.

    Main outcome measures and results: More than a quarter (27%) of primary care physicians perceived a high proportion of unnecessary work tasks. After adjusting for profession, age and gender, the perception of having to perform unreasonable work tasks was positively associated with experiencing role conflicts and with the proportion of organization-related administration and service work tasks.

    Conclusion: Across all staff groups, the perception of unreasonable work tasks was more pronounced among staff with a high proportion of non-patient related administration. Also, the perception of having to perform a large amount of illegitimate work tasks affected the psychosocial work environment negatively, which might influence staffs perception of their professional roles. These results illuminate the importance of decision makers to thoroughly consider the distribution and allocation of non-patient related work tasks among staff in primary care.Key pointsWe observed an interaction between perception of having a large proportion of illegitimate work tasks and impaired psychosocial work environment. • More than a quarter of the primary care physicians perceived a high proportion of unnecessary work tasks.• Across all staff groups, performing unreasonable work tasks was associated with an experience of having role conflicts.• Across all staff groups, a perception of performing unreasonable work tasks was associated with the proportion of non-patient related administrative work tasks.

    Time utilization and perceived psychosocial work environment among staff in Swedish primary care settings2018Ingår i: BMC Health Services Research, ISSN 1472-6963, E-ISSN 1472-6963, Vol. 18, artikel-id 166Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Over the past decades, reorganizations and structural changes in Swedish primary care have affected time utilization among health care professionals. Consequently, increases in administrative tasks have substantially reduced the time available for face-to-face consultations. This study examined how work-time was utilized and the association between work time utilization and the perceived psychosocial work environment in Swedish primary care settings. Methods: This descriptive, multicentre, cross-sectional study was performed in 2014-2015. Data collection began with questionnaire. In the first section, respondents were asked to estimate how their workload was distributed between patients (direct and indirect patient work) and other work tasks. The questionnaire also comprised the Copenhagen Psychosocial Questionnaire, which assessed the psychosocial work environment. Next a time study was conducted where the participants reported their work-time based on three main categories: direct patient-related work, indirect patient-related work, and other work tasks. Each main category had a number of subcategories. The participants recorded the time spent (minutes) on each work task per hour, every day, for two separate weeks. Eleven primary care centres located in southeast Sweden participated. All professionals were asked to participate (n = 441), including registered nurses, primary care physicians, care administrators, nurse assistants, and allied professionals. Response rates were 75% and 79% for the questionnaires and the time study, respectively. Results: All health professionals allocated between 30.9% - 37.2% of their work-time to each main category: direct patient work, indirect patient work, and other work. All professionals estimated a higher proportion of time spent in direct patient work than they reported in the time study. Physicians scored highest on the psychosocial scales of quantitative demands, stress, and role conflicts. Among allied professionals, the proportion of work-time spent on administrative tasks was associated with more role conflicts. Younger staff perceived more adverse working conditions than older staff. Conclusions: This study indicated that Swedish primary care staff spent a limited proportion of their work time directly with patients. PCPs seemed to perceive their work environment in negative terms to a greater extent than other staff members. This study showed that work task allocations influenced the perceived psychosocial work environment.

    Collaboration between non-governmental organizations and public services in health - a qualitative case study from rural Ecuador2016Ingår i: Global Health Action, ISSN 1654-9716, E-ISSN 1654-9880, Vol. 9, artikel-id 32237Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Non-governmental organizations (NGOs) have a key role in improving health in low-and middle-income countries. Their work needs to be synergistic, complementary to public services, and rooted in community mobilization and collective action. The study explores how an NGO and its health services are perceived by the population that it serves, and how it can contribute to reducing barriers to care. Design: A qualitative exploratory study was conducted in remote Ecuador, characterized by its widespread poverty and lack of official governance. An international NGO collaborated closely with the public services to deliver preventative and curative health services. Data were collected using focus group discussions and semistructured interviews with purposively sampled community members, healthcare personnel, and community health workers based on their links to the health services. Conventional qualitative content analysis was used, focusing on manifest content. Results: Emerging themes relate to the public private partnership (PPP), the NGO and its services, and community participation. The population perceives the NGO positively, linking it to healthcare improvements. Their priority is to get services, irrespective of the providers structure. The presence of an NGO in the operation may contribute to unrealistic expectations of health services, affecting perceptions of the latter negatively. Conclusions: To avoid unrealistic expectations and dissatisfaction, and to increase and sustain the populations trust in the organization, an NGO should operate in a manner that is as integrated as possible within the existing structure. The NGO should work close to the population it serves, with services anchored in the community. PPP parties should develop a common platform with joint messages to the target population on the providers structure, and regarding partners roles and responsibilities. Interaction between the population and the providers on service content and their expectations is key to positive outcomes of PPP operations.

    High Degree of Adherence to Statin Therapy Among the Elderly Despite High Frequency of Side Effects2011Ingår i: Healthy Aging & Clinical Care in the Elderly, ISSN 1179-0601, nr 3, s. 1-7Artikel i tidskrift (Övrigt vetenskapligt)
    Abstract [en]

    The aims of the present study were to investigate adherence and side effects of statin therapy in elderly patients ($75 years)after primary statin prescription, to identify possible differences related to whether statin treatment was initiated in primary care or inhospital, and to investigate whether there was any correlation between side effects of statin therapy and statin dose or renal impairment.In two primary health care populations, all patients $75 years of age recently initiated on statin therapy were identified through thepatient data records (n = 90) and asked to complete a questionnaire.Of 68 subjects responding to the questionnaire, 87% reported adherenceto the statin therapy and 29% reported side effects. No statistically significant difference was seen for adherence or frequency ofside effects depending on whether therapy was initiated in primary care or in hospital. In

    Validation of sun exposure and protection index (SEPI) for estimation of sun habits2015Ingår i: Cancer Epidemiology, ISSN 1877-7821, E-ISSN 1877-783X, Vol. 39, nr 6, s. 986-993Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: In both Sweden and Australia high incidence rates of skin cancer have become a major health problem. In prevention and risk communication, it is important to have reliable ways for identifying people with risky sun habits. In this study the validity and reliability of the questionnaire Sun Exposure Protection Index (SEPI), developed to assess individuals sun habits and their propensity to increase sun protection during routine, often brief, clinical encounters, has been evaluated. The aim of our study was to evaluate validity and reliability of the proposed SEPI scoring instrument, in two countries with markedly different ultraviolet radiation environments (Sweden and Australia). Method: Two subpopulations in Sweden and Australia respectively were asked to fill out the SEPI together with the previously evaluated Readiness to Alter Sun Protective Behaviour questionnaire (RASP-B) and the associated Sun-protective Behaviours Questionnaire. To test reliability, the SEPI was again filled out by the subjects one month later. Results: Comparison between SEPI and the questions in the Sun-protective Behaviours Questionnaire, analyzed with Spearmans Rho, showed good correlations regarding sun habits. Comparison between SEPI and RASP-B regarding propensity to increase sun protection showed concurrently lower SEPI mean scores for action stage, but no difference between precontemplation and contemplation stages. The SEPI test-retest analysis indicated stability over time. Internal consistency of the SEPI, assessed with Cronbachs alpha estimation showed values marginally lower than the desired &gt;0.70 coefficient value generally recommended, and was somewhat negatively affected by the question on sunscreen use, likely related to the classic "sunscreen paradox". There were some differences in the performance of the SEPI between the Swedish and Australian samples, possibly due to the influence of "available" sunlight and differing attitudes to behaviour and protection "at home" and on vacation. Conclusions: SEPI appears to be a stable instrument with an overall acceptable validity and reliability, applicable for use in populations exposed to different UVR environments, in order to evaluate individual sun exposure and protection.

    Universal Health Coverage in Marginalized Populations: A Qualitative Evaluation of a Health Reform Implementation in Rural Ecuador2019Ingår i: Inquiry, ISSN 0046-9580, E-ISSN 1945-7243, Vol. 56, artikel-id 0046958019880699Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In 2008, Ecuador underwent a major health reform with the aim of universal coverage. Little is known about the implementation of the reform and its perceived effects in rural parts of the country. The aim of this study was to explore the perceived effects of the 2008 health reform implementation, on rural primary health care services and financial access of the rural poor. A qualitative study using focus group discussions was conducted in a rural region in Ecuador, involving health staff, local health committee members, village leaders, and community health workers. Qualitative content analysis focusing on the manifest content was applied. Three categories emerged from the texts: (1) the prereform situation, which was described as difficult in terms of financial access and quality of care; (2) the reform process, which was perceived as top-down and lacking in communication by the involved actors; lack of interest among the population was reported; (3) the effects of the reform, which were mainly perceived as positive. However, testimonies about understaffing, drug shortages, and access problems for those living furthest away from the health units show that the reform has not fully achieved its intended effects. New problems are a challenging health information system and people without genuine care needs overusing the health services. The results indicate that the Ecuadorean reform has improved rural primary health care services. Still, the reform faces challenges that need continued attention to secure its current achievements and advance the health system further.

    Universal Health Coverage in Rural Ecuador: A Cross-sectional Study of Perceived Emergencies2018Ingår i: Western Journal of Emergency Medicine, ISSN 1936-900X, E-ISSN 1936-9018, Vol. 19, nr 5, s. 889-900Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Introduction: In many low- and middle-income countries emergency care is provided anywhere in the health system; however, no studies to date have looked at which providers are chosen by patients with perceived emergencies. Ecuador has universal health coverage that includes emergency care. However, earlier research indicates that patients with emergencies tend to seek private care. Our primary research questions were these: What is the scope of perceived emergencies?; What is their nature?; and What is the related healthcare-seeking behavior? Secondary objectives were to study determinants of healthcare-seeking behavior, compare health expenditure with expenditure from the past ordinary illness, and measure the prevalence of catastrophic health expenditure related to perceived emergencies. 

    Methods: We conducted a cross-sectional survey of 210 households in a rural region of northwestern Ecuador. The households were sampled with two-stage cluster sampling and represent an estimated 20% of the households in the region. We used two structured, pretested questionnaires. The first questionnaire collected demographic and economic household data, expenditure data on the past ordinary illness, and presented our definition of perceived emergency. The second recorded the number of emergency events, symptoms, further case description, healthcare-seeking behavior, and health expenditure, which was defined as being catastrophic when it exceeded 40% of a household´s ability to pay.

    Results: The response rate was 85% with a total of 74 reported emergency events during the past year (90/1,000 inhabitants). We further analyzed the most recent event in each household (n=54). Private, for-profit providers, including traditional healers, were chosen by 57.4% (95% confidence interval [CI] [44-71%]). Public providers treated one third of the cases. The mean health expenditure per event was $305.30 United States dollars (USD), compared to $135.80 USD for the past ordinary illnesses. Catastrophic health expenditure was found in 24.4% of households. 

    Conclusion: Our findings suggest that the provision of free health services may not be sufficient to reach universal health coverage for patients with perceived emergencies. Changes in the organization of public emergency departments and improved financial protection for emergency patients may improve the situation.

    Differences in sun exposure habits between self-reported skin type and ultraviolet sensitivity measured by phototest2011Ingår i: Photodermatology, Photoimmunology & Photomedicine, ISSN 0905-4383, E-ISSN 1600-0781, Vol. 27, nr 4, s. 190-195Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Traditionally, classification of skin reactivity to ultraviolet (UV) light is based on self-estimation of tendency to burn and tan (Fitzpatricks classification). Although widely accepted, the model has shown to correlate poorly with actual UV sensitivity, measured by phototest. The aim of the present study was to investigate how self-estimated skin type, according to Fitzpatrick, and actual UV sensitivity measured by phototest correlate with sun exposure and protection. Methods: One hundred and sixty-six voluntary patients visiting their general practitioner for investigation of suspicious skin tumours were recruited for the study, and filled out a questionnaire, mapping sun habits and sun protection behaviour, based on five-point Likert responses. The patients reported their skin type (I-VI) according to Fitzpatrick, and a phototest was performed to determine the minimal erythema dose. Results: For most of the questions, high self-estimated UV sensitivity, according to Fitzpatrick, appeared to be associated with a higher level of sun avoidance/protection (P less than 0.05). For actual UV sensitivity, however, the difference in response distribution was only significant for sunscreen use, and did not show a similar apparent association related to the degree of UV sensitivity. Conclusion: Self-estimated skin UV sensitivity, according to Fitzpatricks classification, appears to be a stronger predictor of sun exposure and protection than actual UV sensitivity measured by phototest.

    Self-estimation or Phototest Measurement of Skin UV Sensitivity and its Association with Peoples Attitudes Towards Sun Exposure2014Ingår i: Anticancer Research, ISSN 0250-7005, E-ISSN 1791-7530, Vol. 34, nr 2, s. 797-803Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND:

    Fitzpatrick's classification is the most common way of assessing skin UV sensitivity. The study aim was to investigate how self-estimated and actual UV sensitivity, as measured by phototest, are associated with attitudes towards sunbathing and the propensity to increase sun protection, as well as the correlation between self-estimated and actual UV sensitivity.

    PATIENTS AND METHODS:

    A total of 166 primary healthcare patients filled-out a questionnaire investigating attitudes towards sunbathing and the propensity to increase sun protection. They reported their skin type according to Fitzpatrick, and a UV sensitivity phototest was performed.

    RESULTS:

    Self-rated low UV sensitivity (skin type III-VI) was associated with a more positive attitude towards sunbathing and a lower propensity to increase sun protection, compared to high UV sensitivity. The correlation between the two methods was weak.

    CONCLUSION:

    The findings might indicate that individuals with a perceived low but in reality high UV sensitivity do not seek adequate sun protection with regard to skin cancer risk. Furthermore, the poor correlation between self-reported and actual UV sensitivity, measured by phototest, makes the clinical use of Fitzpatrick's classification questionable.

    Towards a broader use of phototesting: in research, clinical practice and skin cancer prevention2007Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [sv]

    Under de senaste årtiondena har insjuknandet i hudcancer ökat dramatiskt i västvärlden, detta till stor del beroende på förändrade solvanor. Exponering för solens ultravioletta strålning (UVstrålning) samt den individuella ljuskänsligheten i huden utgör två viktiga faktorer av betydelse för uppkomsten av hudcancer. Individer med ökad benägenhet att bli rödbrända i solen löper också ökad risk för hudcancer av solexponering, och behöver således vara extra noga med att skydda sig mot solen. Hur känslig man är mot solljuset kan bedömas antingen genom självskattning (klassificering enligt Fitzpatrick), eller genom att använda ett ljustest. Det sistnämnda är en betydligt mer objektiv metod, men används ändå relativt sparsamt, sannolikt ofta beroende på brist på resurser, tid eller klinisk rutin.

    Det övergripande syftet med avhandlingen var att utveckla och förbättra aspekter på ljustestningsförfarandet med inriktning på att kunna bredda användningen av ljustest inom forskning, klinisk verksamhet och hudcancerprevention. Som ett första steg undersöktes och utvärderades en ny ljustestteknik, baserad på en divergent (spridd) UV-stråle. Genom att belysa huden med ett cirkulärt UV-ljusfält framkallas en cirkulär rodnad (erytem), där diametern på rodnaden står i relation till den individuella ljuskänsligheten i huden. I jämförelse med traditionell ljustestningsmetodik visade sig metoden resultera i en noggrannare uppskattning av ljuskänslighet, samt möjligheten att beskriva ett dos-responsförhållande inom det rodnade hudområdet. Eftersom kanten på den framkallade rodnaden tenderade att bli ganska diffust avgränsad framkom dock, med undantag för speciellt tränade avläsare, svårigheter att läsa av testet med enbart ögats hjälp. Av den anledningen krävdes mer objektiv, hudfysiologisk mätmetodik. I de genomförda studierna användes så kallad Laser Doppler perfusion imaging (LDPI) för detta. Förutom uppskattning av ljuskänsligheten testades den divergenta UV-strålen också som modell för skattning av anti-inflammatorisk effekt av ämnen som appliceras på huden, exempelvis cortison, och visade sig användbar för detta.

    I syfte att öka förutsättningarna för bredare användning av ljustest, genomfördes en studie där försökspersonerna själva fick avläsa ett traditionellt ljustest och rapportera in testresultatet. Resultaten jämfördes med avläsningar utförda av en kunnig avläsare, och visade på god tillförlitlighet.

    Slutligen, med hjälp av den beskrivna självavläsningsproceduren, undersöktes i en primärvårdspopulation, om ljustestning kan vara användbart för att förebygga hudcancer, med inriktning på att påverka individers solvanor, solskyddsbeteende och attityder gentemot solning. I studien jämfördes även olika modeller för att presentera ett preventionsbudskap, och där ett muntligt sådant, förmedlat vid ett läkarbesök, hade ett betydligt bättre genomslag än motsvarande, enbart skriftlig, information. För individer med hög ljuskänslighet bidrog ljustestet till ökat solskyddsbeteende, vilket indikerar att ljustest skulle kunna vara ett användbart verktyg i eftersträvan att förebygga hudcancer speciellt i denna grupp av individer med förhöjd hudcancerrisk.

    Sammanfattningsvis utgör ljustestning med divergent UV-stråle, självavläsning av ljustest samt användning av ljustest vid hudcancerprevention tre nya, tidigare sparsamt undersökta aspekter på ljustestning, för vilka den här avhandlingen visar lovande resultat.

    Abstract [en]

    In a previous publication from our group, phototesting based on a single exposure to a divergent UVB beam with radially decreasing irradiance values was suggested. The aim of the present study was to evaluate technical, practical and biological aspects of the suggested method in normal subjects. Twenty healthy volunteers were provoked on the back with both a collimated beam (four fixed doses, in circular areas with a diameter of 1.5 cm) and the divergent beam (a continuous, radially attenuating dose spectrum covering an area with a diameter of 4.5 cm). Eleven of the subjects were subjected to double provocation with the divergent beam. Assessment was carried out at 6 and 24 h after exposure by measuring the diameter of the reactions both visually and by mapping the skin blood flow change with laser Doppler perfusion imaging (LDPI). Minimal erythemal dose (MED) was determined for both the collimated and the divergent provocation. The reaction diameters were used to decide MED by combination to a mm for mm mapped dose spectrum of the divergent beam profile. Dose-response curves were plotted using the quantitative response data of the LDPI-images against the corresponding dosimetry data. No systematic difference could be proven between LDPI and visual diameters and a 95% confidence interval for the mean difference was calculated to (-0.8, 2.0). Slightly greater diameters were found at the visual assessment performed at 6 h compared to 24 h (95% confidence interval (-0.1, 2.8)). Double provocation showed a good reproducibility both for the visual and the LDPI assessment (P<0.05). The divergent beam provocation allowed a more detailed discrimination of MED compared to the collimated beam provocation. The MED values determined with the divergent beam were, however, generally higher, especially in the lower range of MED values. Technical factors related to the beam divergence and the correct measurement of erythemal effective irradiance are believed to be the explanation for this phenomenon, which is thus correctable. In conclusion, the results from this study support our belief that the phototesting protocol based on a divergent beam constitutes a good opportunity for improved phototesting, since MED and dose-response characteristics may be extracted in more detail from a single UV exposure.

    Abstract [en]

    Background: In both clinical and experimental phototesting, naked eye assessment of erythema has been the main assessment parameter. As with all subjective assessment, variability in recorded results due to variable circumstances around the performance and reading of tests influences reliability and utility of data whether they be interpreted for an individual patient or for a group of research subjects.

    Methods: In the present study, variability in the reporting of diameter of ultraviolet B (UVB) erythema has been studied. The erythematous reactions were assessed by the naked eye and with the help of a millimetre-graded ruler by a group of dermatologists and dermatological trainees. Reaction size, objectively quantified by means of laser Doppler perfusion imaging (LDPI) using thresholding of the reaction perfusion, and known size of UVB provocation were used as yardsticks in order to quantify this variability.

    Results: Agreement between observers, against known size, was excellent for reactions with a sharp border, but for reactions with a diffuse or indistinct border there was a substantial inter-observer variability. This was also true for the comparison between naked-eye reading and LDPI assessment of the reaction size.

    Conclusion: It is concluded that if naked-eye readings are to be the outcome measurement, then provocations/protocols producing distinct borders are an advantage. If borders between provoked and unprovoked skin can be expected to be diffuse, i.e. part of a continuum of response, the use of objective, bioengineering techniques such as LDPI is required. Quantitative methods are also the basis for more detailed presentation and interpretation of test results including information on dose response above the minimal erythema dose.

    Abstract [en]

    Background: Phototesting based on a single exposure to a divergent ultraviolet B (UVB) beam with radially decreasing UVB doses can be used to determine an individual's minimal erythema dose (MED). Laser Doppler perfusion imaging (LDPI) data can be combined with dosimetry data to produce objective dose–response plots in addition to the MED. The aim of this study was to investigate whether the divergent beam protocol could be used to demonstrate and quantify the anti-inflammatory effects of clobetasol diproprionate (Dermovate®), pharmaceutical-grade acetone and a gel vehicle, applied after skin provocation by UVB.

    Method: Sixteen Caucasian subjects were illuminated with the divergent beam on three areas close together on the left side of their upper backs. Two of the provoked areas on each subject were treated with acetone, gel vehicle or Dermovate®, and one area was left untreated as a control. Skin blood perfusion was assessed 6 and 24 h after UVB illumination using LDPI. The reaction diameter, the mean perfusion, and the average dose–response plots for each group and treatment were extracted from the LDPI data.

    Results: Application of the topical steroid clobetasol diproprionate after UVB provocation markedly decreased the inflammatory response. Acetone and the gel vehicle also showed mild anti-inflammmatory effects in two of the parameters but not for the mean perfusion response. The mean diameter differences between controls and treated reactions had predominantly positive 99% confidence intervals. Analysis of the dose–response data at doses higher than the MED showed a linear relationship (0.89≤R2≤0.98) for all reactions but with lower gradients in treated reactions, mostly marked for clobetasol diproprionate.

    Conclusions:  The divergent beam protocol can be used to demonstrate and quantify the effects of topical agents on the UVB reaction, in terms of reaction diameter, mean perfusion and changes in dose–response characteristics. The dose–response approach seems to be applicable even in diagnostic testing of an individual patient's response to UVB.

    Abstract [en]

    Background/objective: The high skin cancer incidence in western society, and its known association with sun exposure habits, makes the area an important target for prevention. We investigated, in a primary healthcare setting, differentiated levels of prevention efforts directed at the propensity of the patient to change his/her sun habits, sun protection behaviour, and attitudes, after information intervention. Additionally, the impact of the performance of a phototest to determine individual sun sensitivity was evaluated. Methods: 308 patients visiting a primary healthcare centre in southern Sweden completed a questionnaire concerning sun habits, sun protection behaviour, and attitudes, and were randomized into one of three groups, representing increasing levels of prevention effort in terms of resources. Feedback on their questionnaire and general preventive sun protection advice was given, in the first group by means of a letter, and in the second and third groups by a doctor's consultation. Group 3 also underwent a phototest, with a self-reading assessment and a written follow-up of the phototest result. Change of sun habits, behaviour, and attitudes, based on the Transtheoretical Model of Behaviour Change and on Likert scale scorings, was evaluated after 6 months, by a repeated questionnaire. Results: Prevention mediated by a doctor's consultation had a clearly better impact on the subjects. The addition of a phototest did not further reinforce this effect in the group as a whole, but it did for a subgroup of individuals with high ultraviolet (UV) sensitivity, as determined by the phototest itself, suggesting that this might actually be a tool to improve outcome in this high-risk group. Conclusion: A personal doctor's consultation is a valuable tool in the effective delivery of preventive information in the general practice setting. In individuals with high UV-sensitivity and thus high risk for skin cancer the performance of a photo-test reinforces a positive outcome in habits, behaviour and attitudes.

    Measuring sun exposure habits and sun protection behaviour using a comprehensive scoring instrument: An illustration of a possible model based on Likert scale scorings and on estimation of readiness to increase sun protection2012Ingår i: Cancer Epidemiology, ISSN 1877-7821, E-ISSN 1877-783X, Vol. 36, nr 4, s. 265-269Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Few attempts to present a comprehensive scoring instrument for sun exposure and protection have been made. The present paper aims to describe a possible set of questions suitable for such an instrument, comprising the most important aspects of sun exposure and protection. Methods: The material from a previously performed intervention study, using a questionnaire based on Likert scales and on the Transtheoretical Model of Behaviour Change (TTM), was utilised. 213 primary healthcare patients filled in the questionnaire and were randomised into two groups receiving sun protection advice, in Group 1 in letter-form, and in Group 2 orally during a doctor's consultation. In the original study, increased sun protection/readiness to increase sun protection was demonstrated for several items in Group 2, at six months. To compose a comprehensive scoring instrument, five questions concerning sun exposure/protection (intentional tanning, sunscreen use, choice of SPF, number of occasions with sunburn, and time spent in the sun at midday), were selected to give a 20 point behavioural score. Similarly, four TTM-based questions (giving up sunbathing, using clothes for sun protection, using sunscreens, and staying in the shade) gave a 16 point "propensity-to-change"-score. Results: At follow-up, increased sun protection reflected in the behavioural score occurred only in Group 2 (p<0.001). For the propensity-to-change-score, increased readiness to increase sun protection occurred in both groups, but the change was significantly higher in Group 2 (p<0.05). Categorisation of the 20 point behavioural score, into three risk levels, revealed a significantly higher shift of subjects moving to a lower risk level in Group 2 compared to Group 1 (p<0.05). Conclusions: In conclusion, twinning of a summarised Likert scale behavioural score with a TTM-based propensity-to-change-score seems promising for the creation of a questionnaire-based, comprehensive scoring instrument for sun exposure and protection.

    Reliability of self-assessed reading of skin tests: A possible approach in research and clinical practice?2010Ingår i: Dermatologi Online, ISSN 1087-2108, E-ISSN 1087-2108, Vol. 16, nr 2Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In the investigation and management of skin disease, various testing protocols are of importance. The extent to which clinical judgments and decisions on therapy are supported by the performance of such testing can be affected negatively by the lack of time and resources for the performance of tests. In the present study, the possibility of utilizing self-reporting by subjects is investigated. Determination of irritation threshold for sodium lauryl sulphate (SLS) and minimal erythema dose for ultraviolet B were chosen as suitable self-reading protocols. Test reading by 26 subjects instructed in "present" or "absent" reporting of test reactions were compared to trained observer reading. Absolute agreement was found in 76.9 percent of the SLS reactions and in 85 percent of the UVB reactions. Weighted Kappa for the agreement between observations showed values of 0.76 for the SLS reactions and 0.83 for UVB reactions. We conclude that use of the protocols here studied, and other test protocols modified to accommodate a binomial assessment outcome ("+" or "-"), could well lead to an increase in the performance of skin testing. This could be a qualitative advantage for diagnosis and management of skin diseases. Additionally, population studies and even prevention initiatives could be facilitated. © 2010 Dermatology Online Journal.

    Från evidens till praktik: utvärdering av ett nytt arbetssätt för att använda evidens i vårdens förbättringsarbete2014Rapport (Övrigt vetenskapligt)
    Abstract [sv]

    Att hälso- och sjukvården ska bedrivas utifrån vetenskap och beprövad erfarenhet är allmänt vedertaget. Ett snabbt ökande kunskapsflöde innebär dock höga krav på såväl behandlande enheter som på den enskilda läkaren, som i sitt vardagsarbete ska fatta medicinska beslut utifrån bästa möjliga kunskap. Att på ett strukturerat och effektivt sätt underlätta spridningen av, och tillgången till, evidensbaserad kunskap utgör en stor utmaning för hela samhället, inklusive forskarsamhället. För vården är det en utmaning att använda kunskapen.

    Syftet med projektet var att utveckla, pröva och utvärdera en lokalt anpassad modell för implementering av evidensbaserad kunskap i klinisk verksamhet, baserad på ett arbetssätt som tidigare prövats i Kanada (Alberta Ambassador Programme), och som modifierades för att passa de lokala förutsättningarna i Östergötland, där projektet genomfördes. Som kliniskt beslutsproblem att studera valdes förskrivning av läkemedlet pregabalin, som används vid epilepsi, generaliserat ångestsyndrom (GAD) och neuropatisk smärta. Valet grundades på att läkemedlet är dyrt i förhållande till alternativen, på en  ökande förskrivning med stor variationinom länet, samt på rapporter om  förskrivning utanför rekommenderadesjukdomstillstånd. Sammantaget pekade detta på osäkerhet i hur läkemedlet skulle användas och därmed utrymme för förbättring.

    Projektet genomfördes i fyra steg: 1) Framtagning av ett övergripande evidensdokument för pregabalin, 2) Expertgruppsmöten (uppdelade på psykiatri/smärta) där det utifrån evidensdokumentet arbetades fram ett sammanfattande evidensunderlag/expertrekommendation, 3) Dialogmöten på ett antal sjukhuskliniker/vårdcentraler, samt 4) Uppföljning och utvärdering. En webbenkät skickades till deltagarna direkt efter genomförda dialogmöten, samt efter tio veckor. Resultatet visade att deltagarna till övervägande del var nöjda med innehållet i och formerna för dialogen. En majoritet bedömde innehållet som värdefullt för kliniska ställningstaganden, och att det vid tioveckorsuppföljningen fått spridning på den egna enheten. Statistik över receptförskrivningen av pregabalin tio månader före och efter interventionen, visade för länets tre psykiatriska kliniker (vilka före interventionen skilt sig drastiskt åt i fråga om förskrivning per 1000 patienter) en tydlig utjämning i förskrivning mellan klinikerna. För övriga sjukhuskliniker och vårdcentraler gick det däremot inte att se någon tydlig förändring i detta avseende.

    Sammanfattningsvis bedöms den prövade modellen för implementering av evidensbaserad kunskap ha fungerat väl utifrån det praktiska genomförandet och baserat på deltagarnas omdömen, och bör därav kunna prövas även inom andra områden.

    CBT-based group intervention for insomnia – a non-randomized trial in primary care2016Ingår i: Journal of Sleep Disorders and Therapy, E-ISSN 2167-0277, Vol. 5, nr 230Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Abstract

    Insomnia is a major health problem, commonly leading to pharmacological treatment. During recent years, behavioural therapies have gained stronger therapeutic position, not least cognitive behavioural therapy (CBT). The aim was to investigate the effect of a CBT-based group intervention for insomnia in primary care, by means of self-reported sleep quality and duration. In addition, cortisol in saliva, as a biological marker of stress was tested. Methods: Fifty participants with primary insomnia, attending primary care, were enrolled, 35 receiving the intervention, and 15 serving as control. The intervention group was recruited during the first two study years, and controls during a following third year, without randomization. The intervention included eight CBT-based group sessions, each two-hour long and led by a psychologist, with 4-6 participants in each group. Controls were handled in accordance with ordinary clinical routine, including pharmacological intervention. Sleep onset time, duration and quality were assessed before and after the intervention, by patients filling-out the Pittsburgh Sleep Quality Index (PSQI). Insomnia severity was assessed by the Insomnia Severity Index (ISI). Also, cortisol in saliva levels were monitored. Results: In the intervention group, significant shortening of mean sleep onset time, from 60-27 min (p<0.05) was observed, and a prolongation of mean sleep duration time, from 298-358 min (p<0.05), in neither case seen in the control group, although between-group difference was not statistically significant. Both PSQI and ISI means scores were significantly improved in the intervention group, from 12.1 to 7.9 (p<0.05) and from 19.4 to 12.5 (p<0.01), respectively, in the latter case significantly more so than in the control group (p<0.05). No effect on cortisol levels was detected, in either group. In conclusion, the tested eight-session CBT-based group intervention for insomnia appears to reduce severity and duration of insomnia, and to shorten time before falling asleep, when provided in primary care.

    Inter-observer variability in reading of phototest reactions with sharply or diffusely delineated borders2008Ingår i: Skin research and technology, ISSN 0909-752X, E-ISSN 1600-0846, Vol. 14, nr 4, s. 397-402Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: In both clinical and experimental phototesting, naked eye assessment of erythema has been the main assessment parameter. As with all subjective assessment, variability in recorded results due to variable circumstances around the performance and reading of tests influences reliability and utility of data whether they be interpreted for an individual patient or for a group of research subjects.

    Methods: In the present study, variability in the reporting of diameter of ultraviolet B (UVB) erythema has been studied. The erythematous reactions were assessed by the naked eye and with the help of a millimetre-graded ruler by a group of dermatologists and dermatological trainees. Reaction size, objectively quantified by means of laser Doppler perfusion imaging (LDPI) using thresholding of the reaction perfusion, and known size of UVB provocation were used as yardsticks in order to quantify this variability.

    Results: Agreement between observers, against known size, was excellent for reactions with a sharp border, but for reactions with a diffuse or indistinct border there was a substantial inter-observer variability. This was also true for the comparison between naked-eye reading and LDPI assessment of the reaction size.

    Conclusion: It is concluded that if naked-eye readings are to be the outcome measurement, then provocations/protocols producing distinct borders are an advantage. If borders between provoked and unprovoked skin can be expected to be diffuse, i.e. part of a continuum of response, the use of objective, bioengineering techniques such as LDPI is required. Quantitative methods are also the basis for more detailed presentation and interpretation of test results including information on dose response above the minimal erythema dose.

    Phototesting with a divergent UVB beam in the investigation of anti-inflammatory effects of topically applied substances2003Ingår i: Photodermatology, Photoimmunology & Photomedicine, ISSN 0905-4383, E-ISSN 1600-0781, Vol. 19, nr 4, s. 195-202Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Phototesting based on a single exposure to a divergent ultraviolet B (UVB) beam with radially decreasing UVB doses can be used to determine an individual's minimal erythema dose (MED). Laser Doppler perfusion imaging (LDPI) data can be combined with dosimetry data to produce objective dose–response plots in addition to the MED. The aim of this study was to investigate whether the divergent beam protocol could be used to demonstrate and quantify the anti-inflammatory effects of clobetasol diproprionate (Dermovate®), pharmaceutical-grade acetone and a gel vehicle, applied after skin provocation by UVB.

    Method: Sixteen Caucasian subjects were illuminated with the divergent beam on three areas close together on the left side of their upper backs. Two of the provoked areas on each subject were treated with acetone, gel vehicle or Dermovate®, and one area was left untreated as a control. Skin blood perfusion was assessed 6 and 24 h after UVB illumination using LDPI. The reaction diameter, the mean perfusion, and the average dose–response plots for each group and treatment were extracted from the LDPI data.

    Results: Application of the topical steroid clobetasol diproprionate after UVB provocation markedly decreased the inflammatory response. Acetone and the gel vehicle also showed mild anti-inflammmatory effects in two of the parameters but not for the mean perfusion response. The mean diameter differences between controls and treated reactions had predominantly positive 99% confidence intervals. Analysis of the dose–response data at doses higher than the MED showed a linear relationship (0.89≤R2≤0.98) for all reactions but with lower gradients in treated reactions, mostly marked for clobetasol diproprionate.

    Conclusions:  The divergent beam protocol can be used to demonstrate and quantify the effects of topical agents on the UVB reaction, in terms of reaction diameter, mean perfusion and changes in dose–response characteristics. The dose–response approach seems to be applicable even in diagnostic testing of an individual patient's response to UVB.

    Sun protection advice mediated by the general practitioner: An effective way to achieve long-term change of behaviour and attitudes related to sun exposure?2011Ingår i: Scandinavian Journal of Primary Health Care, ISSN 0281-3432, E-ISSN 1502-7724, Vol. 29, nr 3, s. 135-143Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective. To investigate, in primary health care, differentiated levels of prevention directed at skin cancer, and how the propensity of the patients to change sun habits/sun protection behaviour and attitudes towards sunbathing were affected, three years after intervention. Additionally, the impact of the performance of a phototest as a complementary tool for prevention was evaluated. Design. Randomized controlled study. Setting and subjects. During three weeks in February, all patients andgt;= 18 years of age registering at a primary health care centre in southern Sweden were asked to fill in a questionnaire mapping sun exposure habits, attitudes towards sunbathing, and readiness to increase sun protection according to the Transtheoretical Model of Behaviour Change (TTM) (n = 316). They were randomized into three intervention groups, for which sun protection advice was given, in Group 1 by means of a letter, and in Groups 2 and 3 orally during a personal GP consultation. Group 3 also underwent a phototest to demonstrate individual skin UV sensitivity. Main outcome measures. Change of sun habits/sun protection behaviour and attitudes, measured by five-point Likert scale scores and readiness to increase sun protection according to the TTM, three years after intervention, by a repeated questionnaire. Results. In the letter group, almost no improvement in sun protection occurred. In the two doctors consultation groups, significantly increased sun protection was demonstrated for several items, but the difference compared with the letter group was significant only for sunscreen use. The performance of a phototest did not appear to reinforce the impact of intervention. Conclusion. Sun protection advice, mediated personally by the GP during a doctors consultation, can lead to improvement in sun protection over a prolonged time period.

    Sun Exposure Habits and Health Risk-related Behaviours Among Individuals with Previous History of Skin Cancer2013Ingår i: Anticancer Research, ISSN 0250-7005, E-ISSN 1791-7530, Vol. 33, nr 2, s. 631-638Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Aim: The aim of the present study was to investigate possible associations between UV exposure and other health risk behaviours in different social environments and in regard to previous history of skin cancer. Patients and Methods: In two closely-located, equally-sized cities in Sweden, representing different social environments (blue collar and white collar), patients aged 55-69 years, diagnosed with skin cancer (study group, n=489) or seborrhoeic keratosis (control group, n=664), were identified through a regional Health Care Register, and were given a questionnaire mapping for sun habits, tobacco smoking, alcohol use, and physical activity. Results: A previous history of skin cancer was associated with reduced UV exposure (pandlt;0.01) and increased UV protection (pandlt;0.00.1), higher alcohol consumption (pandlt;0.05), and higher level of physical activity (pandlt;0.05). Smoking was more common among subjects frequently sunbathing and rarely using sunscreen, but frequent sunbathing was positively associated with physical activity (pandlt;0.05). Daily smoking and risky drinking habits were more common in the blue collar social environment, while no differences were seen for sun habits in this respect. Conclusion: A previous history of skin cancer appears to promote increased UV protection. In contrast to alcohol/smoking habits, no association between social environment and sun habits was found.

    Modifierad brittisk modell kortade ledtid till datortomografi av kolon2015Ingår i: Läkartidningen, ISSN 0023-7205, E-ISSN 1652-7518, Vol. 112Artikel i tidskrift (Refereegranskat)
    Abstract [sv]

    Vid misstanke om kolorektal cancer är det angeläget att patienter där misstankegraden är hög får genomgå snar utredning och diagnostik. På många håll i landet föreligger oönskat långa väntetider för sådan utredning.

    Användningen av ett evidensbaserat beslutsstöd för kolonutredning, baserat på riktlinjer från brittiska NICE (National Institute for Health and Care Excellence), implementerades på 8 vårdcentraler i Östergötland.

    Efter implementeringen förkortades ledtider till datortomografi av kolon, diagnos och behandling.

    Beslutsstödet bidrog till att patienter där graden av misstanke om kolorektal cancer var låg kunde styras om till att genomgå datortomografi av buken i stället för av kolon.

    Plasma Matrix Metalloproteinase-9 Levels Predict First-Time Coronary Heart Disease: An 8-Year Follow-Up of a Community-Based Middle Aged Population2015Ingår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 10, nr 9, s. e0138290-Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background The enzyme in matrix metalloproteinase (MMP)-9 has been suggested to be an important determinant of plaque degradation. While several studies have shown elevated levels in patients with coronary heart disease, results in prospective population based studies evaluating MMP-9 in relation to first time coronary events have been inconclusive. As of today, there are four published studies which have measured MMP-9 in serum and none using plasma. Measures of MMP-9 in serum have been suggested to have more flaws than measures in plasma. Aim To investigate the independent association between plasma levels of MMP-9 and first-time incidence of coronary events in an 8-year follow-up. Material and Methods 428 men and 438 women, aged 45-69 years, free of previous coronary events and stroke at baseline, were followed-up. Adjustments were made for sex, age, socioeconomic position, behavioral and cardiovascular risk factors, chronic disease at baseline, depressive symptoms, interleukin-6 and C-reactive protein. Results 53 events were identified during a risk-time of 6 607 person years. Hazard ratio (HR) for MMP-9 after adjustment for all covariates were HR = 1.44 (1.03 to 2.02, p = 0.033). Overall, the effect of adjustments for other cardiovascular risk factors was low. Conclusion Levels of plasma MMP-9 are independently associated with risk of first-time CHD events, regardless of adjustments. These results are in contrast to previous prospective population-based studies based on MMP-9 in serum. It is essential that more studies look at MMP-9 levels in plasma to further evaluate the association with first coronary events.

    Near infrared and skin impedance spectroscopy - a possible support in the diagnostic process of skin tumours in primary health care.2015Ingår i: Skin research and technology, ISSN 0909-752X, E-ISSN 1600-0846, Vol. 21, nr 4, s. 493-499Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND/PURPOSE: The global incidence of skin cancer has increased drastically in recent decades, especially in Australia and Northern Europe. Early detection is crucial for good prognosis and high survival rates. In general, primary care physicians have considerably lower sensitivity and specificity rates for detection of skin cancer, compared to dermatologists. A probable main reason for this is that current diagnostic tools are subjective in nature, and therefore diagnostic skills highly depend on experience. Illustratively, in Sweden, approximately 155 500 benign skin lesions are excised unnecessarily every year. An objective instrument, added to the clinical examination, might improve the diagnostic accuracy, and thus promote earlier detection of malignant skin tumours, as well as reduce medical costs associated with unnecessary biopsies and excisions. The general aim of this study was to investigate the usefulness of the combination of near infrared (NIR) and skin impedance spectroscopy as a supportive tool in the diagnosis and evaluation of skin tumours in primary health care.

    METHODS: Near infrared and skin impedance data were collected by performing measurements on suspect malignant, premalignant and benign tumours in the skin of patients seeking primary health care for skin tumour evaluation. The obtained data were analysed using multivariate analysis and compared with the diagnosis received by the conventional diagnostic process.

    RESULTS: The observed sensitivity and specificity rates were both 100%, when discriminating malignant and premalignant skin tumours from benign skin tumours, and the observed sensitivity and specificity for separating malignant skin tumours from premalignant and benign skin tumours were also 100%, respectively.

    CONCLUSION: The results of this study indicate that the NIR and skin impedance spectroscopy may be a useful supportive tool for the general practitioner in the diagnosis and evaluation of skin tumours in primary health care, as a complement to the visual assessment.

    Phototesting based on a divergent beam: a study on normal subjects2001Ingår i: Photodermatology, Photoimmunology & Photomedicine, ISSN 0905-4383, E-ISSN 1600-0781, Vol. 17, nr 4, s. 189-196Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In a previous publication from our group, phototesting based on a single exposure to a divergent UVB beam with radially decreasing irradiance values was suggested. The aim of the present study was to evaluate technical, practical and biological aspects of the suggested method in normal subjects. Twenty healthy volunteers were provoked on the back with both a collimated beam (four fixed doses, in circular areas with a diameter of 1.5 cm) and the divergent beam (a continuous, radially attenuating dose spectrum covering an area with a diameter of 4.5 cm). Eleven of the subjects were subjected to double provocation with the divergent beam. Assessment was carried out at 6 and 24 h after exposure by measuring the diameter of the reactions both visually and by mapping the skin blood flow change with laser Doppler perfusion imaging (LDPI). Minimal erythemal dose (MED) was determined for both the collimated and the divergent provocation. The reaction diameters were used to decide MED by combination to a mm for mm mapped dose spectrum of the divergent beam profile. Dose-response curves were plotted using the quantitative response data of the LDPI-images against the corresponding dosimetry data. No systematic difference could be proven between LDPI and visual diameters and a 95% confidence interval for the mean difference was calculated to (-0.8, 2.0). Slightly greater diameters were found at the visual assessment performed at 6 h compared to 24 h (95% confidence interval (-0.1, 2.8)). Double provocation showed a good reproducibility both for the visual and the LDPI assessment (P<0.05). The divergent beam provocation allowed a more detailed discrimination of MED compared to the collimated beam provocation. The MED values determined with the divergent beam were, however, generally higher, especially in the lower range of MED values. Technical factors related to the beam divergence and the correct measurement of erythemal effective irradiance are believed to be the explanation for this phenomenon, which is thus correctable. In conclusion, the results from this study support our belief that the phototesting protocol based on a divergent beam constitutes a good opportunity for improved phototesting, since MED and dose-response characteristics may be extracted in more detail from a single UV exposure.

    Prognostic risk factors of first recurrence in patients with primary stages I-II cutaneous malignant melanoma - from the population-based Swedish melanoma register2017Ingår i: Journal of the European Academy of Dermatology and Venereology, ISSN 0926-9959, E-ISSN 1468-3083, Vol. 31, nr 9, s. 1468-1474Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background Prognostic factors in patients with localized primary cutaneous malignant melanoma (CMM) are well described. However, prognostic factors for recurrence are less documented. Objectives The aim of this study was to identify prognostic risk factors for first recurrence in patients with localized stages I-II CMM using population-based data. Methods This study included 1437 CMM patients registered in one region of Sweden during 1999-2012 follow-up through 31 December 2012. To identify first recurrence of CMM disease, data from a care data warehouse, the pathology and radiology department registries were used. Patients were also followed through a census register and the national Cause of Death Register. Results The 5- and 10-year recurrence-free survival (RFS) were 85.7% and 81.2%, respectively. The most common site of first recurrence was regional lymph node metastasis closely followed by distant metastasis. After adjusting for all prognostic factors, women had 50% lower risk of recurrence than men (HR = 0.5, 95% CI 0.4-0.7) and patients = 70 had higher risk compared to patients 55-69 years (HR = 1.7, 95% CI 1.2-2.5). Other significant prognostic factors for risk of recurrence were tumour thickness, presence of ulceration, Clarks level of invasion and histogenetic type. Conclusion Tumour thickness was found to be the predominant risk factor for recurrence. The prognostic factors for recurrence coincided with prognostic factors for CMM death. The most common site of first recurrence in stages I-II CMM is regional lymph node (42.8%) closely followed by distant metastases (37.6%), a fact which has to be taken into consideration when choosing follow-up strategies.

    Sustainable effect of individualised sun protection advice on sun protection behaviour: a 10-year follow-up of a randomised controlled study in primary care.2019Ingår i: BJGP open, ISSN 2398-3795, Vol. 3, nr 3, artikel-id bjgpopen19X101653Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: In the light of increasing skin cancer incidences worldwide, preventive measures to promote sun protection in individuals with risky sun habits have continued relevance and importance.

    AIM: To report the long-term effect of individualised sun protection advice given in primary health care (PHC), on sun habits and sun protection behaviour.

    DESIGN & SETTING: In 2005, 309 PHC patients were enrolled in a randomised controlled study performed in a Swedish PHC setting.

    METHOD: At baseline, the study participants completed a Likert scale-based questionnaire, mapping sun habits, propensity to increase sun protection, and attitudes towards sun exposure, followed by randomisation into three intervention groups, all receiving individualised sun protection advice: in Group 1 (n = 116) by means of a letter, and in Group 2 (n = 97) and 3 (n = 96) communicated personally by a GP. In Group 3, participants also underwent a skin ultraviolet-sensitivity phototest, with adjusted sun protection advice based on the result. A repeated questionnaire was administered after 3 and 10 years.

    RESULTS: Statistically significant declines were observed in all groups for sun exposure mean scores over time. When using a cumulative score, according to the Sun Exposure and Protection Index (SEPI), significantly greater decrease in SEPI mean score was observed in Groups 2 and 3 (GP), compared to Group 1 (letter); P<0.01. The addition of a phototest did not enhance the effect of the intervention.

    CONCLUSION: Individualised sun protection advice mediated verbally by the GP can lead to sustained improvement of sun protective behaviour.

    Community-acquired pneumonia in primary care: clinical assessment and the usability of chest radiography2016Ingår i: Scandinavian Journal of Primary Health Care, ISSN 0281-3432, E-ISSN 1502-7724, Vol. 34, nr 1, s. 21-27Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objectives: To investigate the diagnostic value of different clinical and laboratory findings in pneumonia and to explore the association between the doctors degree of suspicion and chest X-ray (CXR) result and to evaluate whether or not CXR should be used routinely in primary care, when available. Design: A three-year prospective study was conducted between September 2011 and December 2014. Setting: Two primary care settings in Linkoping, Sweden. Subjects: A total of 103 adult patients with suspected pneumonia in primary care. Main outcome measures: The physicians recorded results of a standardized medical physical examination, including laboratory results, and rated their suspicion into three degrees. The outcome of the diagnostic variables and the degree of suspicion was compared with the result of CXR. Results: Radiographic pneumonia was reported in 45% of patients. When the physicians were sure of the diagnosis radiographic pneumonia was found in 88% of cases (p&lt;0.001), when quite sure the frequency of positive CXR was 45%, and when not sure 28%. Elevated levels of C-reactive protein (CRP)50mg/L were associated with the presence of radiographic pneumonia when the diagnosis was suspected (p&lt;0.001). Conclusion: This study indicates that CXR can be useful if the physician is not sure of the diagnosis, but when sure one can rely on ones judgement without ordering CXR.

    Primary healthcare utilisation and self-rated health among patients with Irritable Bowel Syndrome: What are the impacts of comorbidities, gastrointestinal symptom burden, sense of coherence and stress?2019Ingår i: Journal of Psychosomatic Research, ISSN 0022-3999, E-ISSN 1879-1360, Vol. 119Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objectives: Irritable Bowel Syndrome (IBS) is a chronic gastrointestinal disease associated with impaired quality of life and an increased use of healthcare services. Self-ratings of health have proven a powerful predictor of health outcomes. The aim of this study was to evaluate the unique impacts of comorbidities, gastrointestinal symptoms, perceived stress and sense of coherence on the number of healthcare contacts and self-rated health of IBS patients in Swedish primary care. Methods: In this cross-sectional study, 186 primary-care IBS patients and 360 non-IBS patients (as a reference group) were administrated a test battery of validated questionnaires. Data on comorbidities and healthcare-seeking frequency were obtained from a registry. Results: In the reduced multivariable logistic regression model, average days of abdominal pain/week (OR = 0.83, 95% CI = 0.72-0.96), age (OR = 0.95, 95% CI = 0.92-0.97) and sense of coherence (OR = 1.07, 95% CI = 1.03-1.11) remained independent, statistically significant predictors of IBS (and non-IBS) patients reporting good health. Only the number of comorbidities in general (OR = 1.22, 95% CI = 1.14-1.32) and sleep disorders in particular (OR = 5.40, 95% CI = 1.85-15.76) independently predicted high levels of primary healthcare utilisation among IBS patients. Conclusion: Lack of gastrointestinal symptoms, a high sense of coherence and younger age were associated with better self-rated health in both IBS and non-IBS patients. The number of comorbidities in general and sleep disorders in particular were associated with frequent PHC contacts in IBS patients. The association between frequent primary-care contacts and sleep disorders was not seen in the control group, indicating a unique association with IBS patients.

    BackgroundIn tissue viability imaging (TiVi), an assessment method for skin erythema, correct orientation of skin position from provocation to assessment optimizes data interpretation.

    Validation of phototesting for estimation of individual skin ultraviolet sensitivity based on a lengthwise attenuating ultraviolet B field.2015Ingår i: Journal of Medical Engineering & Technology, ISSN 0309-1902, E-ISSN 1464-522X, Vol. 39, nr 2, s. 91-8Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Conventional skin UV-sensitivity phototesting is based on semi-quantitative assessment of minimal erythema dose (MED). This study demonstrates a method for quantitative MED determination, using a lengthwise attenuating UVB-field combined with tissue viability imaging (TiVi). The study aim was to investigate the agreement between MED acquired by traditional phototest and by the new method. Forty-seven voluntary subjects underwent phototesting with a traditional phototest and with the new technique. Test reading, carried out after 24 h, showed moderate agreement between the methods when assessed with TiVi (Kappa value=0.46) and visually (Kappa value=0.48). For the new method, no systematic differences were seen between outcomes assessed with TiVi or visually (95% CI for the mean difference=-1.6-2.0). In conclusion, the results give promising support for the concept of achieving a more precise MED estimation by combining continuous attenuating UV fields with new available bioengineering technology.

    Effect of oral diclofenac intake on faecal calprotectin2016Ingår i: Scandinavian Journal of Gastroenterology, ISSN 0036-5521, E-ISSN 1502-7708, Vol. 51, nr 1, s. 28-32Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background. NSAIDs are a known source of increased faecal calprotectin (FC) levels. Currently, there is a lack of knowledge about how long it takes for an increased FC level to return to normal after NSAID intake. Objective. The aim was to investigate how oral diclofenac intake affects FC levels and assess how long it takes for an increased FC level to return to normal after oral diclofenac intake. Material and methods. Thirty healthy volunteers received diclofenac 50 mg three times daily for 14 days. Participants provided a stool sample on Days 0, 2, 4, 7, 14 during intake and Days 17, 21, 28 after discontinuation. FC levels were then followed at 7-day intervals until normalization. Results. During diclofenac intake, eight participants (27%) had FC levels exceeding the upper limit of normal (median, 76 mu g/g; range, 60-958 mu g/g), corresponding to 8.3% of measurements. FC was not constantly increased and became normal in most participants during diclofenac intake. FC levels were on average significantly higher during intake (M = 9.5, interquartile range (IQR) = 13.4) than on baseline (M = 7.5, IQR = 0.0), p = 0.003. After discontinuation, two participants had increased FC on Days 17 and 21, respectively. No significant differences in FC levels were found between baseline and measurements after discontinuation. Two weeks after discontinuation, all participants had normal FC levels. Conclusions. Short-term oral diclofenac intake is associated with increased FC levels. However, the likelihood of an increased test result is low. Our results suggest that 2 weeks of diclofenac withdrawal is sufficient to get an uninfluenced FC test result.

    Blood pressure and all-cause mortality: a prospective study of nursing home residents2016Ingår i: Age and Ageing, ISSN 0002-0729, E-ISSN 1468-2834, Vol. 45, nr 6, s. 826-832Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Aim: To explore the natural course of blood pressure development and its relation to mortality in a nursing home cohort.

    Methods: A cohort of 406 nursing home residents in south east Sweden was followed prospectively for 30 months. Participants were divided into four groups based on systolic blood pressure (SBP) at baseline. Data were analysed using a Cox regression model with all-cause mortality as the outcome measurement; paired Student t-tests were used to evaluate blood pressure development over time.

    Results: During follow-up, 174 (43%) people died. Participants with SBP <120 mmHg had a hazard ratio for mortality of 1.56 (95% confidence interval, 1.08–2.27) compared with those with SBP 120–139 mmHg, adjusted for age and sex. Risk of malnutrition or present malnutrition was most common in participants with SBP <120 mmHg; risk of malnutrition or present malnutrition estimated using the Mini Nutritional Assessment was found in 78 (71%). The levels of SBP decreased over time independent of changes in anti-hypertensive medication.

    Conclusions: In this cohort of nursing home residents, low SBP was associated with increased all-cause mortality. SBP decreased over time; this was not associated with altered anti-hypertensive treatment. The clinical implication from this study is that there is a need for systematic drug reviews in elderly persons in nursing homes, paying special attention to those with low SBP.

    Atrial fibrillation (AF) and co-morbidity in elderly. A population based survey of 85 years old subjects.2011Ingår i: Archives of gerontology and geriatrics (Print), ISSN 0167-4943, E-ISSN 1872-6976, Vol. 52, nr 3, s. e170-e175Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The occurrence of AF increases sharply with age. The aim of this study was to explore and compare prevalent co-morbidity and self-estimated health-related quality of life (HRQoL) in subjects with AF versus subjects with sinus rhythm or pacemaker in 85 years old subjects. We analyzed data from a population of 336 eighty-five years old subjects participating in the Elderly in Linköping Screening Assessment (ELSA-85) study. Medical history was obtained from postal questionnaire, medical records and during medical examination that included a physical examination, cognitive tests, non-fasting venous blood samples and electrocardiographic (ECG) examination. 19% had an ECG showing AF. There were very few significant differences regarding medical history, self-estimated quality of life (QoL), laboratory- and examination findings and use of public health care between the AF group and the non-AF group. The study showed that the population of 85 years old subjects with AF was surprisingly healthy in terms of prevalent co-existing medical conditions, healthcare contacts and overall HRQoL. We conclude that elderly patients with AF do not in general have increased co-morbidity than subjects without AF.

    Sun Exposure and Protection Index (SEPI) and Self-Estimated Sun Sensitivity2018Ingår i: Journal of Primary Prevention, ISSN 0278-095X, E-ISSN 1573-6547, Vol. 39, nr 5, s. 437-451Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The incidence of skin cancer is increasing worldwide, mostly because of increasing exposure to ultraviolet (UV) radiation from the sun. The Sun Exposure and Protection Index (SEPI) questionnaire, developed in Linkoping and validated in Sweden and Australia, is used to map sun habits, sun protection behaviour, and readiness to increase sun protection. We sought to examine differences in sun habits or sun protection behaviour and propensity to increase sun protection, based on SEPI as related to self-estimated skin UV sensitivity according to the Fitzpatrick classification. The study population comprised students at Linkoping University, who were asked to complete the SEPI questionnaire. We examined differences in sun habits and sun protection behaviour according to skin type and gender. Individuals with lower UV sensitivity had significantly riskier sun habits and sun protection behaviour and were significantly less likely to increase sun protection. Women spent significantly more time tanning than men, more time in the midday sun, used sunscreen more frequently, and were more likely to seek the shade for sun protection. Individuals with higher UV sensitivity were significantly more likely to increase sun protection; individuals with low UV sensitivity tended to have a riskier attitude to sunbathing. In conclusion, self-estimated skin type and gender are important factors influencing sun exposure habits and sun protection behaviour.
