    A mixed method evaluation of a group-based educational programme for CPAP use in patients with obstructive sleep apnea2013In: Journal of Evaluation In Clinical Practice, ISSN 1356-1294, E-ISSN 1365-2753, Vol. 19, no 1, p. 173-184Article in journal (Refereed)
    Abstract [en]

    Rationale, aims and objectives  Continuous positive airway pressure (CPAP) treatment of obstructive sleep apnea (OSA) has a low long-term adherence. Educational interventions are few and sparsely described regarding content, pedagogical approach and participants' perceptions. The aim was to describe adherence to CPAP treatment, knowledge about OSA/CPAP, as well as OSA patients' perceptions of participating in a group-based programme using problem-based learning (PBL) for CPAP initiation. Educational programme  The PBL programme incorporated elements from theories and models concerning motivation and habits. Tutorial groups consisting of four to eight patients met at six sessions during 6 months. Methods  A sequential explanatory mixed method design was used on 25 strategically selected patients. Quantitative data regarding, clinical variables, OSA severity, CPAP use, and knowledge were collected at baseline, after 2 weeks and 6 months. Qualitative data regarding patients' perceptions of participation were collected after 6 months by semi-structured interviews using a phenomenographic approach. Results  72% of the patients were adherent to CPAP treatment after 2 weeks and 6 months. All patients improved their baseline knowledge about OSA and CPAP after 2 weeks and sustained it after 6 months. Anxiety and fear, as well as difficulties and needs were motivational factors for participation. Patients described the difficulties of behavioural change, an awareness that improvements do not occur immediately, a realization of the importance of both technical and emotional support and the need for a healthier lifestyle. Conclusion and practice implications  A group-based programme using PBL seems to facilitate adaptive and developmental learning and result in acceptable CPAP adherence levels.

    Validation of the CPAP Habit Index-5: A Tool to Understand Adherence to CPAP Treatment in Patients with Obstructive Sleep Apnea.2014In: Sleep Disorders, ISSN 2090-3545, E-ISSN 2090-3553, Vol. 2014, p. 1-9, article id 929057Article in journal (Refereed)
    Abstract [en]

    Long-term adherence to continuous positive airway pressure (CPAP) is low among patients with obstructive sleep apnea (OSA). The potential role of "habit" in sustaining adherence to CPAP use has not been studied. This study aimed to establish the relevance of habit to CPAP adherence, via validation of an adaptation of the Self-Report Habit Index (the CPAP Habit Index-5; CHI-5). Analyses focused on the homogeneity, reliability, and factor structure of the CHI-5 and, in line with theoretical predictions, its utility as a predictor of long-term CPAP adherence in middle-aged patients with OSA. A prospective longitudinal design was used. 117 patients with objectively verified OSA intended for CPAP treatment were recruited. Data was collected via clinical examinations, respiratory recordings, questionnaires, and CPAP devices at baseline, 2 weeks, 6 months, and 12 months. The CHI-5 showed satisfactory homogeneity interitem correlations (0.42-0.93), item-total correlations (0.58-0.91), and reliability ( α = 0.92). CHI-5 data at 6 months showed a one-factor solution and predicted 63% of variance in total CPAP use hours after 12 months. Based on the satisfactory measurement properties and the high amount of CPAP use variance it explained, the CHI-5 can be seen as a useful tool in clinical practice.

    Factors associated with undiagnosed obstructive sleep apnoea in hypertensive primary care patients2012In: Scandinavian Journal of Primary Health Care, ISSN 0281-3432, E-ISSN 1502-7724, Vol. 30, no 2, p. 107-113Article in journal (Refereed)
    Abstract [en]

    Objective. In hypertensive primary care patients below 65 years of age, (i) to describe the occurrence of undiagnosed obstructive sleep apnoea (OSA), and (ii) to identify the determinants of moderate/severe OSA. Design. Cross-sectional. Setting. Four primary care health centres in Sweden. Patients. 411 consecutive patients (52% women), mean age 57.9 years (SD 5.9 years), with diagnosed and treated hypertension (BP andgt; 140/90). Main outcome measures. Occurrence of OSA as measured by the apnoea hypopnoea index (AHI). Results. Mild (AHI 5-14.9/h) and moderate/severe (AHI andgt; 15/h) OSA were seen among 29% and 30% of the patients, respectively. Comparing those without OSA with those with mild or moderate/severe OSA, no differences were found in blood pressure, pharmacological treatment (anti-hypertensive, anti-depressive, and hypnotics), sleep, insomnia symptoms, daytime sleepiness, or depressive symptoms. Obesity (BMI andgt; 30 kg/m(2)) was seen in 30% and 68% of the patients with mild and moderate/severe OSA, respectively. Male gender, BMI andgt; 30 kg/m(2), snoring, witnessed apnoeas, and sleep duration andgt; 8 hours were determinants of obstructive sleep apnoea. Conclusion. Previously undiagnosed OSA is common among patients with hypertension in primary care. Obesity, snoring, witnessed apnoeas, long sleep duration, and male gender were the best predictors of OSA, even in the absence of daytime sleepiness and depressive symptoms.

    Symptom profile of undiagnosed obstructive sleep apnoea in hypertensive outpatients in primary care: a structural equation model analysis2012In: Quality in Primary Care, ISSN 1479-1072, E-ISSN 1479-1064, Vol. 20, no 4, p. 287-298Article in journal (Refereed)
    Abstract [en]

    BACKGROUND:

    Obstructive sleep apnoea (OSA) has been linked to hypertension in sleep clinic populations, but little is known about the symptom profile of undiagnosed OSA in hypertensive outpatients in primary care.

    AIM:

    To explore characteristics associated with undiagnosed  OSA in hypertensive primary care patients.

    METHODS:

    Cross-sectional design, including 411 consecutive patients (52% women), mean age 57.9 years (standard deviation [SD] 5.9 years), with diagnosed hypertension (blood pressure >140/90 mmHg) from four primary care centres. All subjects  underwent a full-night, home-based, respiratory recording to establish the presence and severity of OSA. Clinical variables, medication and comorbidities, as well as data from self-rating scales regarding symptoms/characteristics, insomnia, excessive daytime sleepiness, depressive symptoms  and health were collected during a clinical examination. Factor analyses and structural equation modelling (SEM) were used to explore the relationships between self-rated symptoms, clinical characteristics and objectively verified diagnosis of OSA. Main outcome: Measures symptom  profile of undiagnosed OSA (as measured by the Apnoea/Hypopnoea Index [AHI]) in hypertensive outpatients in primary care.

    RESULTS:

    Fifty-nine percent of the patients had an AHI ≥ 5/hour indicating OSA. An exploratory factor analysis based on 19 variables yielded a six-factor model  (anthropometrics, blood pressure, OSA-related symptoms, comorbidity, health complaints and physical activity) explaining 58% of the variance. SEM analyses showed strong significant associations between anthropometrics (body mass index, neck circumference, waist circumference) (0.45), OSA-related  symptoms (snoring, witnessed apnoeas, dry mouth) (0.47) and AHI. No direct effects of OSA on comorbidities, blood pressure, dyssomnia or self-rated health were observed.

    CONCLUSION:

    OSA was highly prevalent and was directly associated with anthropometrics and OSA-related symptoms  (snoring, witnessed apnoeas and dry mouth in the morning). When meeting patients with hypertension, these characteristics could be used by general practitioners to identify patients who are in need of referral to a sleep clinic for OSA evaluation.

    Gender differences in respiratory disturbance, sleep and daytime sleepiness in hypertensive patients with different degrees of obesity2013In: European Journal of Cardiovascular Nursing, ISSN 1474-5151, E-ISSN 1873-1953, Vol. 12, no 2, p. 140-149Article in journal (Refereed)
    Abstract [en]

    Background: Hypertension (HT) and obesity have both been linked to obstructive sleep apnoea (OSA). Difficulties have been described in identifying patients with OSA in primary care, causing low referral rates to sleep clinics. Increased knowledge about gender-specific characteristics and symptoms may help to identify patients. Aim: The aim was to describe gender differences regarding undiagnosed OSA, self-rated sleep, insomnia and daytime sleepiness in middle-aged primary care patients with HT and different degrees of obesity. Methods: A cross-sectional design was used and 394 patients (52.5% women), mean age 57.8 years (SD 6.7 years), with HT (BP >140/90 mmHg) were included. Clinical examinations, respiratory recordings and self-rated scales regarding OSA symptoms, sleep, insomnia and daytime sleepiness were used. Body mass index (BMI) was classified according to the criteria from the National Institutes of Health. Results: Pre-obesity and obesity classes I and II were seen among 53%, 26% and 8% of the men and 37%, 19% and 14% of the women, respectively. Occurrence of mild, moderate and severe OSA increased significantly across the BMI classes for both genders (p<0.01). Ninety percent of the men and 80% of the women in obesity class II had OSA. Insomnia was prevalent in obese patients. Other clinical variables did not differ between BMI classes or genders. Conclusion: The occurrence of overweight/obesity and OSA was high among both genders. A high BMI might be a convenient clinical marker for healthcare personnel to identify hypertensive patients with possible OSA in need of further evaluation and treatment.

    The attitudes to CPAP treatment inventory: development and initial validation of a new tool for measuring attitudes to CPAP treatment2011In: Journal of Sleep Research, ISSN 0962-1105, E-ISSN 1365-2869, Vol. 20, no 3, p. 460-471Article in journal (Refereed)
    Abstract [en]

    ontinuous positive airway pressure (CPAP) is the treatment of choice for obstructive sleep apnoea syndrome (OSAS), but low adherence rates are common. The aim was to develop the attitudes to CPAP treatment inventory (ACTI), and to investigate the validity and reliability of the instrument among patients with OSAS. ACTI was developed on the basis of: (i) in-depth interviews with 23 patients; (ii) examination of the scientific literature; and (iii) consensus agreement of a multi-professional expert panel. This yielded five different types of attitudes to CPAP treatment. A prospective longitudinal design was used. Two-hundred and eighty-nine patients with OSAS were recruited at three different CPAP centres. Data were collected with ACTI and obtained from medical records. The homogeneity and internal consistency reliability were satisfactorily reflected by the item-total correlations (0.59-0.81) and Cronbachs alpha (0.89), respectively. Construct validity was confirmed with factor analysis (principal component analysis with orthogonal rotation; PCF). The PCF based on baseline data resulted in a one single-factor solution explaining 69% of the total variance. A confirmatory factor analysis was performed 2 weeks after CPAP initiation, resulting in the same factor solution. No indication of uniform differential item functioning was found. The predictive validity was tested with receiver operating characteristic analyses, and a cut-off of 10 on the ACTI gave a sensitivity of 93% and a specificity of 44% for CPAP termination within 6 months. The satisfactory measurement properties of this new pragmatic instrument are promising and indicate that ACTI can be useful in clinical practice to reliably measure attitudes to CPAP treatment.

    15-year efficacy of uvulopalatopharyngoplasty based on objective and subjective data2011In: Acta Oto-Laryngologica, ISSN 0001-6489, E-ISSN 1651-2251, Vol. 131, no 12, p. 1303-1310Article in journal (Refereed)
    Abstract [en]

    Conclusions: This follow-up showed a stable and significant decrease in median oxygen desaturation index 4% (ODI(4)) values over the years. Approximately two-thirds of the patients fulfilled the success criteria (ODI4 reduction of 50% and andlt;20) after 15 years. A majority had improved/cured excessive daytime sleepiness (EDS) and were satisfied. No increased mortality rate was seen. Objectives: To evaluate sleep apnoea recordings and symptoms in patients with obstructive sleep apnoea syndrome 15 years after uvulopalatopharyngoplasty (UPPP) compared to baseline and previous follow-ups. Methods: This was a non-randomized, prospective intervention study on 50 patients who underwent UPPP during 1985-88. Their initial median age was 49 years (range 38-71) and ODI4 was 26.5 (4-82). Results: In all, 13 patients had died; 26 patients underwent sleep apnoea recordings. Median ODI4 had decreased from 26.5 (range 4-82) to 8.5 (0-60), p andlt; 0.01, a mean reduction of 52%; 65% of patients achieved the success criteria. One-third was objectively categorized as non-snorers. Median body mass index was unchanged. The questionnaires were answered by 32 of 37 patients; 88% reported improved or cured EDS and 78% were satisfied. Pharyngeal disturbances ratings were low. The standardized mortality rate did not differ from the general Swedish population.

    Decisive Situations Affecting Partners Support to Continuous Positive Airway Pressure-Treated Patients With Obstructive Sleep Apnea Syndrome A Critical Incident Technique Analysis of the Initial Treatment Phase2012In: Journal of Cardiovascular Nursing, ISSN 0889-4655, E-ISSN 1550-5049, Vol. 27, no 3, p. 228-239Article in journal (Refereed)
    Abstract [en]

    Background and Research Objective: Effective treatment of obstructive sleep apnea syndrome (OSAS) with continuous positive airway pressure (CPAP) can reduce morbidity and mortality, but adherence rates are low. The partner has an important role in supporting the patient, but this role may be adversely affected by difficulties during the early phase of the CPAP initiation. The aim of this study was to explore and describe decisive situations affecting partners support to patients with OSAS and how the partners manage these situations during the initial phase of CPAP treatment. Subjects and Methods: A qualitative descriptive design using critical incident technique was used. A total of 542 decisive situations affecting partners support and 222 situations describing managing were collected by means of interviews with 25 strategically selected partners of patients with CPAP treated OSAS. Results: Adverse effects, limited effect, practical and psychosocial problems, limited presence, and inappropriate initiation emerged as negative influences on the partners support. A well-functioning treatment, improvements, high motivation, and receiving support from others were identified as positive influences on the partners support. The partner managed the situations by letting the patient handle the CPAP treatment by himself/herself, by handling the treatment together with the patient, or taking over the handling of CPAP treatment. Conclusion: Increased knowledge about the different situations that affect the partners support negatively or positively and how these situations are managed by partners can be used in educational situations involving both patients and partners during CPAP initiation.

    Using mode and maximum values from the Numeric Rating Scale when evaluating postoperative pain management and recovery2013In: Journal of Clinical Nursing, ISSN 0962-1067, E-ISSN 1365-2702, Vol. 22, no 5-6, p. 638-647Article in journal (Refereed)
    Abstract [en]

    Aims and objectives. To (1) examine the clinical applicability of compiled mode and maximum values from the Numeric Rating Scale (NRS) by comparing the correspondence between patient perceptions of pain and pain values from monitoring records, as well as (2) to study the relationship between mode and maximum values and self-assessed ability for early postoperative recovery. Background. Documentation of pain remains a problem despite recommendations of quality improvements. To examine the correlation between patient perceptions and documented pain therefore becomes important. Few have studied how pain affects recovery. Design. A quantitative cross-sectional design was used in which 157 postoperative patients answered a questionnaire on pain intensity and recovery. A parallel examination of pain in monitoring records was conducted. Results. A total of 57% had a mode value calculated from records between 0 and 3 on postoperative day 1 and 69% on day 2. A maximum value between 4 and 10 was found in monitoring records for 73% on day 1 and for 67% on day 2. The correspondence between mode value from monitoring records and the patients retrospective perceptions was 88% for NRS 03 and 92% between maximum value and NRS 410. The correlation between documented pain and retrospectively identified pain for mode value of the NRS in all (010) was rather weak (r=0 center dot 37), while maximum value had a stronger correlation (r=0 center dot 53). Conclusion. Mode and maximum values could be used as outcome measures when evaluating postoperative pain. Pain affects recovery negatively, but more research is needed to strengthen the evidence for the use and clarify the link between pain and recovery. Relevance to clinical practice. International organisations emphasise the importance of improving pain assessment. Mode and maximum values are easy to compile for nurses and can, together with assessments of how experienced pain levels affect postoperative recovery, improve treatment of postoperative pain.

    Factors Associated With Increased Risk for Dementia in Individuals Age 80 Years or Older With Congestive Heart Failure2014In: Journal of Cardiovascular Nursing, ISSN 0889-4655, E-ISSN 1550-5049, Vol. 29, no 1, p. 82-90Article in journal (Refereed)
    Abstract [en]

    BACKGROUND AND RESEARCH OBJECTIVE:: An increasing body of evidence shows that individuals diagnosed with congestive heart failure (CHF) are at a higher risk for dementia. However, the prevalence rate of dementia among persons with CHF in very old individuals has not been previously reported, and little is known about the comorbidities that place old persons with CHF at a higher risk for dementia. The aim of this study was to compare the prevalence of dementia in individuals 80 years or older who have CHF with that in individuals without CHF and to identify factors related to dementia in individuals diagnosed with CHF.

    METHODS:: A total of 702 participants from a Swedish population-based longitudinal study (Octogenerian Twin) were included. The group consisted of same-sex twin pairs, age 80 years or older, and 138 participants had CHF. Dementia was diagnosed according to criteria in the Diagnostic and Statistical Manual of Mental Disorders, Third Edition, Revised. Generalized estimating equations including gender, age and educational level, waist circumference, diabetes, hypertension, smoking, depression, and blood values were used in a case-control analysis.

    RESULTS:: Individuals with CHF had a significantly higher prevalence of vascular dementia, 16% vs 6% (P < 0.001), and of all types of dementia, 40% vs 30% (P < 0.01), than those not diagnosed with CHF. The generalized estimating equation models showed that depression, hypertension, and/or increased levels of homocysteine were all associated with a higher risk for dementia in individuals with CHF. Diabetes was specifically associated with an increased risk for vascular dementia.

    CONCLUSIONS:: The prevalence of dementia was higher among individuals with CHF than in those without CHF. Diabetes, depression, and hypertension in patients with CHF require special attention from healthcare professionals because these conditions are associated with an elevated risk for dementia. Higher levels of homocysteine were also found to be a marker of dementia in patients with CHF. Further research is needed to identify the factors related to dementia in individuals 80 years or older diagnosed with CHF.

    The influence of heart failure on longitudinal changes in cognition among individuals 80 years of age and older2012In: Journal of Clinical Nursing, ISSN 0962-1067, E-ISSN 1365-2702, Vol. 21, no 7-8, p. 994-1003Article in journal (Refereed)
    Abstract [en]

    Aim.  The aim of this study was to examine the relationship between heart failure and specific cognitive abilities in octogenarians with regard to level and change over time.

    Background.  Cognitive impairment is influenced by many factors, and the impact of heart failure is debated. Intact cognitive ability is crucial for successful self-care in patients with heart failure. Middle-aged patients with heart failure seem to have an increased risk of cognitive impairment. No studies have examined the association between heart failure and longitudinal cognitive changes in octogenarians (individuals 80 years and older).

    Design.  A prospective longitudinal design.

    Methods.  Cognitive tests were carried out five times (1991–2002) in 702 octogenarians from the Swedish Twin Registry, including same-sex twin pairs. The test battery included the measurement of processing speed, visuospatial ability, short-term, episodic and semantic memory. Latent growth curve modelling was employed to measure change and performance over time and compares the group diagnosed with heart failure to individuals without a heart failure diagnosis.

    Results.  At baseline, the participants’ mean age was 83·5 years, 67% were women and 13% suffered from heart failure. Individuals diagnosed with heart failure scored significantly lower in spatial abilities and episodic memory than participants not diagnosed with heart failure. Moreover, measures of episodic memory declined more over time in individuals diagnosed with heart failure. There were no significant differences between the groups in other cognitive tests.

    Conclusion.  Spatial problems and episodic memory have implications for everyday life. This might contribute to decreased adherence to prescribed therapy and self-care management and lead to socio-behavioural problems because of an impaired capacity to drive, read and write.

    Relevance to clinical practice.  Nurses should take into account in their assessment that cognitive impairment may restrain elderly heart failure patient’s ability to make decisions and perform self-care actions. Patient education strategies should also be adapted to cognitive ability.

    Sleep-wake activity rhythm and health-related quality of life among patients with coronary artery disease and in a population-based sampleAn actigraphy and questionnaire study2013In: International Journal of Nursing Practice, ISSN 1322-7114, E-ISSN 1440-172X, Vol. 19, no 4, p. 390-401Article in journal (Refereed)
    Abstract [en]

    The aim of this study was to explore whether there are gender differences in sleep and health-related quality of life in patients with coronary artery disease (CAD) and a matched population-based sample and to see how subjectively rated sleep is associated with actigraphy. Secondly, to explore whether factors that predict patients sleep quality could be identified. Fifty-seven patients with stable CAD and 47 participants from a population-based sample were included. All participants completed the Uppsala Sleep Inventory (USI), the Epworth Sleepiness Scale and the SF-36. Actigraphy recordings and a sleep diary were performed for seven 24-h periods. Multiple stepwise regression analysis showed that sleep duration, sleep onset latency, nocturnal awakenings, vitality (SF-36) and body mass index explained 60% of the sleep quality outcome (USI). Sleep duration, sleep efficiency and fragmentation index assessed with actigraphy and sleep diary accounted for 36% of the sleep quality outcome (diary). The result can form the basis for a non-pharmacological, self-care programme supported and led by nurses.

    Abstract [en]

    The aim of this study was to explore whether there are gender differences in sleep and health related quality of life in patients with coronary artery disease CAD and a matched population-based sample and to see how subjectively rated sleep is associated with actigraphy. Secondly, whether factors that predict patients´ sleep quality could be identified. Fifty-seven patients with stable CAD and forty-seven participants from a population-based sample were included. All participants completed the Uppsala Sleep Inventory (USI), the Epworth Sleepiness Scale and the SF-36. Actigraphy recordings and a sleep diary were performed for 7 days. Multiple stepwise regression analysis showed that sleep duration, sleep onset latency, nocturnal awakenings, vitality (SF-36) and BMI explained 60% of the sleep quality outcome (USI) (P<0.0001). Sleep duration, sleep efficiency and fragmentation index assessed with actigraphy and sleep diary accounted for 36% of the sleep quality outcome (diary, P<0.0001). The result can form the basis for a non-pharmacological, self-care programme supported and led by nurses.

    Sleep, arousal and health-related quality of life in men and women with coronary artery disease.2011In: Journal of Clinical Nursing, ISSN 0962-1067, E-ISSN 1365-2702, Vol. 20, no 19-20, p. 2787-2801Article in journal (Refereed)
    Abstract [en]

    Aim. To evaluate whether there are gender differences in insomnia, sleep quality, sleep efficiency (%), general arousal, disease-specific and health-related quality of life in patients with coronary artery disease, compared with an age- and gender-matched randomly selected group from the general population.

    Background.  There are gender difference effects of sleep disturbances in the general population, but this perspective among patients with coronary artery disease has been poorly analysed.

    Design.  In this prospective study, comparative, descriptive and model testing designs were used.

    Method.  The patients with coronary artery disease, 556 men and 324 women aged 25–86, were compared with a matched population-based group. Data were collected by validated and reliability-tested questionnaires.

    Results.  The prevalence of severe insomnia varied between 17–44% in all four groups. The severe insomniac coronary artery disease patients displayed a two- or threefold higher presleep arousal, had two hours shorter nocturnal sleep duration/night and were more limited in their physical exercise level than the population-based group. Gender differences in sleep quality, sleep efficiency (%) and general arousal disappeared with increased insomnia severity.

    Conclusions.  Independent of gender, age and comorbidity, physical exercise, general arousal behaviour and delayed poststress recovery after mental stress were found to have a negative impact on the coronary artery disease patients’ sleep quality and sleep efficiency (%), interfering with their health-related quality of life. The variables significantly explained 41% of the sleep quality outcome and 29% of the sleep efficiency (%).

    Relevance to clinical practice.  Insomnia because of hyperarousal behaviour can be an important factor in the development of an individual self-care management programme supported by a healthcare team.

    Perceptions of how sleep is influenced by rest, activity and health in patients with coronary heart disease: A phenomenographical study2007In: Scandinavian Journal of Caring Sciences, ISSN 0283-9318, E-ISSN 1471-6712, Vol. 21, no 4, p. 467-475Article in journal (Refereed)
    Abstract [en]

    A framework is needed for identifying internal and external factors essential for the nursing management of psychological supportive health care and education for patients' self-care in sleep. In order to generate more knowledge from the patient's perspective, the aim of this study was to describe how patients with coronary artery disease (CAD) perceive that their sleep is influenced by rest, activity and health in outpatient care. Qualitative interviews were performed with 33 outpatients. The data were analysed using a phenomenographic method. Three descriptive categories of the phenomenon were described: my lifestyle is reflected in my sleep behaviour, handling the practices around tiredness and sleep, and feelings of negative and positive efficacy. Feelings of tiredness, fatigue and sleepiness were different pre-sleep stages, but were also related to the patient's adaptation and recovery. Creating one's own personal time and feelings of efficacy gave an inner sense of strength which is indicated as being particularly important in managing stress and the demands of everyday life in a satisfactory manner. From a contextual, holistic perspective on health, it is important to identify the patient's needs, symptoms and intentional or unintentional self-care management strategies regarding sleep and lifestyle. To promote a positive health outcome it is essential to identify sleeplessness behaviour and perceived self-efficacy for self-care in sleep. © 2007 Nordic College of Caring Science.

    Clinical characteristics and mortality risk in relation to obstructive and central sleep apnoea in community-dwelling elderly individuals: a 7-year follow-up2012In: Age and Ageing, ISSN 0002-0729, E-ISSN 1468-2834, Vol. 41, no 4, p. 468-474Article in journal (Refereed)
    Abstract [en]

    Methods: a total of 331 community-dwelling elderly aged 71-87 years underwent a clinical examination and one-night polygraphic recordings in their homes. Mortality data were collected after seven years. Results: a total of 55% had SDB, 38% had OSA and 17% had CSA. Compared with those with no SDB and OSA, more participants with CSA had a left ventricular ejection fraction less than 50% (LVEF less than 50%) ischaemic heart disease (IHD) and transient ischaemic attack (TIA)/stroke. There was no difference in the rate of IHD and TIA/stroke between OSA and no SDB, but more LVEF less than 50% was found in those with OSA. CSA significantly increased the risk for all-cause (P = 0.002) and CV mortality (P = 0.018) by more than two times. After adjustments for CV disease, diabetes and the biomarker NT-pro-brain natriuretic peptide CSA associations to all-cause mortality and CV mortality lost significance. Conclusion: OSA, in persons greater than 75 years does not appear to be associated with cardiovascular disease (CVD) disease or mortality, whereas CSA might be a pathological marker of CVD and impaired systolic function associated with higher mortality.

    Abstract [en]

    The relationships between heart failure (HF), sleep-disordered breathing (SDB), insomnia, depressive symptoms, and excessive daytime sleepiness (EDS), as well as their relationship to Global Perceived Health (GPH) in an elderly community-dwelling population, have not been explored. Data from 331 community-dwelling elderly (71-87 years old) were collected by echocardiography, polygraphy, and specific questionnaires. Factor analyses and structural equation modeling were used to explore the relationships between HF, SDB, sleep, psychosocial factors, and GPH. Exploratory and confirmatory factor analyses derived a 5-factor model representing SDB, insomnia, systolic function, breathlessness/physical function, and psychosocial function. Structural equation modeling analyses were used to explore the relationships between the 5 factors and to GPH. Sleep-disordered breathing had a weak effect on systolic function, but no effects on any of the other factors or GPH were found. Psychosocial function and breathlessness/physical function directly affected GPH. Indirect effects on GPH, mediated by psychosocial function, were found for breathlessness/physical function and insomnia. Systolic function also had an indirect effect on GPH. The fact that SDB in the elderly has no obvious negative associations to sleep complaints or GPH does not exclude them from being adequately treated for SDB. However, the present study has shown that SDB, by means of self-rated sleep complaints and health-related quality of life, can be problematic to detect. Psychosocial function was the most important factor for perceived GPH as it had a direct effect, as well as mediated the factors breathlessness/physical function and insomnia effects, on GPH. This study indicates that interventions in clinical practice targeting psychosocial dysfunction, such as depressive symptoms, could help to improve GPH in the elderly with or without HF.

    Difficulties in Identification of Sleep Disordered Breathing in an Outpatient Clinic for Heart Failure– A Case Study2014In: Annals of Nursing and Practice, ISSN 2379-9501, Vol. 1, no 3, article id 1011Article in journal (Refereed)
    Abstract [en]

    Sleep disordered breathing (SDB) is prevalent in patients with heart failure (HF). The clinical signs of newly diagnosed HF and untreated SDB may overlap and patients in need of SDB treatment can therefore be difficult to identify in patients participating in disease management programmes (DMP). The aim was to describe the care process of two patients with HF involved in a DMP, focusing on the difficulties to identify and initiate treatment of SDB.A prospective case study design was used to follow one male (70 yrs) and one female (74 yrs) patient during 18 months at a Swedish University hospital. It took 5 to 10 months from diagnosis of HF until optimal treatment was reached for their heart conditions and 12 to 17 months until SDB was treated. None of the patients complained of poor sleep, but suffered from fatigue. In the male SDB was detected by the wife’s complaints of her husband’s snoring, apnoeas and restless sleep. In the female, SDB was detected after a detailed assessment of fatigue which was shown to be sleepiness. After optimal treatment of HF but before imitation of SDB treatment both cases cardiac function improved. For the female case improvements also were found in the blood pressure. SDB treatment improved fatigue in both patients. Initiation of HF treatment and self-care routines, as well as identification of SDB is complex and time consuming. Treatment of HF and SDB can improve sleep, cardiac function as well as disturbing associated symptoms.

    Sickness behavior in community-dwelling elderly associations with impaired cardiac function and inflammation2014In: Biological Research for Nursing, ISSN 1099-8004, E-ISSN 1552-4175, Vol. 16, no 1, p. 105-113Article in journal (Refereed)
    Abstract [en]

    Sickness behavior is a cluster of symptoms that occur as a response to an infection and alterations in the inflammatory response. Under normal circumstances, sickness behavior is fully reversible once the pathogen has been cleared. Aging and chronic illness such as heart failure are associated with enhanced inflammatory activity that lasts for a long duration and no longer represents an adaptive response. The aim of this study was to explore whether inflammation mediates the relationship between impaired cardiac function and a symptom cluster including anhedonia, fatigue, and sleepiness, which might represent sickness behavior in community-dwelling elders. Structural equation modeling (SEM) showed that the factor impaired cardiac function (i.e., N-terminal fragment of pro-brain natriuretic peptide, left ventricular ejection fraction, and the heart failure medications angiotensin converting enzyme inhibitor, angiotensin receptor blockade, β-blocker, and diuretics) was associated with both inflammation (i.e., C-reactive protein; β = .26) and the symptom cluster (β = .31). Inflammation had a significant direct, but smaller, association with the symptom cluster (β = .21). By this pathway, inflammation also mediated an indirect association between impaired cardiac function and the symptom cluster (β = .05). Including creatinine, blood glucose, ischemic heart disease, previous and current tumor, respiratory disease, age, and body mass index in the SEM model did not change these associations. Our results imply that some aspects of the symptom panorama in elderly individuals with impaired cardiac function or heart failure could represent sickness behavior.

    Insular cortex activation in a patient with "sensed presence"/ecstatic seizures2011In: EPILEPSY and BEHAVIOR, ISSN 1525-5050, Vol. 20, no 4, p. 714-718Article in journal (Refereed)
    Abstract [en]

    Objective: Seizures with an aura of a "sensed presence," a religious emotion, or feelings of euphoria (ecstatic seizures) are characterized by heightened self-awareness. A previous case report on a patient with epilepsy and "sensed presence" as an aura described hypoperfusion in both temporal lobes and a local ictal increase in the left frontoparietal area. A reexamination of the data was suggested by a recent study of patients with ecstatic seizures, which proposed that hyperactivation of the left anterior insula might be a potential cause. Methods: We reanalyzed the laboratory data on the case with "sensed presence" aura using a fusion of SPECT and MR images of the brain, which had not previously been available, and a close examination of the subdural ictal EEG registrations. Results: Examination of the ictal EEG recordings from subdural strip electrodes implanted subtemporally and temporally on both sides showed that seizure activity occurred first at the most medial subtemporal electrode on the left side. From an anatomical point of view, this electrode position is close to the ventral aspect of the left anterior insula, and it is possible that the seizure activity was initiated there. Reexamination of the SPECT data after fusion with contemporary MR images clearly indicated that the region of strong hyperactivation overlies the left anterior insula. Hyperactive regions also appear on the midinsula bilaterally. Together with the neurophysiological ictal EEG, this evidence supports a reinterpretation that this aura of "sensed presence" can be attributed to hyperactivation of the left anterior insula. Conclusion: The present findings support the proposal that ecstatic seizures or "sensed presence" auras can originate from the left anterior insula, a region that has been suggested to engender self-awareness associated with positive feelings.

    How active are patients with idiopathic normal pressure hydrocephalus and does activity improve after shunt surgery? A controlled actigraphic study.2012In: Clinical neurology and neurosurgery (Dutch-Flemish ed. Print), ISSN 0303-8467, E-ISSN 1872-6968, Vol. 115, no 2, p. 192-196Article in journal (Refereed)
    Abstract [en]

    INTRODUCTION: Actigraphy allows long-time evaluation of physical activity and resting behaviour in a normal environment. The aim of this study was, by use of actigraphy, to measure motor function, energy expenditure and resting/sleeping time in idiopathic normal pressure hydrocephalus (iNPH) patients before and after surgery, and compare the results with healthy individuals (HI).

    SUBJECTS AND METHODS: 33 patients (mean 73 year) and 17 HI (mean 73 year) participated. Actigraphy with SenseWear (BodyMedia Inc., Pittsburgh, PA, USA) was recorded in the iNPH patients before and three months postoperatively and twice in the HI with a three-month interval. In addition, gait speed, timed up and Go (TUG) and MMSE were registered pre- and post-operatively.

    RESULTS: During daytime the patients took fewer steps (p<0.001) and their total energy expenditure (TEE) was lower (p<0.01) than in the HI. Twenty patients were evaluated pre- and post-operatively and no change in either the number of steps, TEE, or time spent lying/sleeping after surgery could be detected. iNPH patients had lower gait speed, worse TUG and MMSE compared to the HI. Gait and TUG improved after surgery.

    CONCLUSION: Actigraphy in iNPH patients indicated reduced ambulatory activity and lower energy expenditure compared to HI preoperatively. This did not change postoperatively in spite of improved TUG and gait speed.

    Restless legs syndrome during and after pregnancy and its relation to snoring2012In: Acta Obstetricia et Gynecologica Scandinavica, ISSN 0001-6349, E-ISSN 1600-0412, Vol. 91, no 7, p. 850-855Article in journal (Refereed)
    Abstract [en]

    Objective. To study development of restless legs syndrome (RLS) during and after pregnancy, and whether RLS is related to snoring or other pregnancy-related symptoms. Design. Prospective study. Setting. Antenatal care clinics in the catchment area of Linkoping university hospital, Sweden. Population. Five hundred consecutively recruited pregnant women. Methods. Sleep disturbances, including symptoms of RLS and snoring, were assessed with questionnaires in each trimester. A complementary questionnaire was sent three years after delivery to women experiencing symptoms of RLS during pregnancy. Main outcome measures. Symptoms of RLS in relation to snoring in each trimester. Results. Symptoms of RLS were reported by 17.0% of the women in the first trimester, by 27.1% in the second trimester and by 29.6% in the third trimester. Snoring in the first trimester was correlated to increased prevalence of RLS in all three trimesters (p= 0.003, 0.017 and 0.044 in the first, second and third trimester, respectively). No correlation was found between RLS and anemia, parity or body mass index. Among the women who experienced RLS, 31% still had symptoms three years after delivery. Fifty-eight per cent of those whose symptoms had disappeared stated that this happened within one month after delivery. Conclusions. Symptoms of RLS progressed most between the first and second trimester. Women who snored in the first or second trimester of pregnancy had a higher prevalence of RLS in the third trimester, which indicates that snoring in early pregnancy might predict RLS later. Symptoms of RLS disappear quite soon after delivery, but about one-third of women with RLS during pregnancy may still have symptoms three years after childbirth.

    Snoring during pregnancy and its relation to sleepiness and pregnancy outcome - a prospective study2014In: BMC Pregnancy and Childbirth, ISSN 1471-2393, E-ISSN 1471-2393, Vol. 14, no 15Article in journal (Refereed)
    Abstract [en]

    Background: The incidence of snoring and sleepiness is known to increase during pregnancy, and this might impact maternal health and obstetric outcome. However, the association between snoring and sleepiness during pregnancy is not fully understood. This study was aimed at investigating the development of snoring during pregnancy and prospectively assessing if there is an association between snoring and sleepiness or adverse pregnancy outcomes, such as preeclampsia, mode of delivery, and fetal complications. Methods: Consecutively recruited pregnant women (n = 500) received a questionnaire concerning snoring and sleep at the 1st and 3rd trimester of pregnancy. The women who had rated their frequency of snoring at both occasions (n = 340) were divided into subgroups according to the development of snoring they reported and included in the subsequent analyses. Additional medical data were collected from the medical records. Results: The frequency of snoring was 7.9% in the 1st trimester and increased to 21.2% in the 3rd trimester of pregnancy. The women who snored already in early pregnancy had significantly higher baseline BMI (p = 0.001) than the women who never snored, but snoring was not associated with the magnitude of weight gain during pregnancy. Snoring women were more likely to experience edema in late pregnancy than the non-snorers. Women who started to snore during pregnancy had higher Epworth Sleepiness Scores than the non snorers in both early and late pregnancy. No significant association between obstetric outcome and snoring was found. Conclusion: Snoring does increase during pregnancy, and this increase is associated with sleepiness, higher BMI at the start of pregnancy and higher prevalence of edema, but not with weight gain.

To obtain a description of topics discussed, the transcripts were analysed using content analysis. The patterns of dominance for the respective topic and participant were explored from the framework of analysis that treats dominance. less thanbrgreater than less thanbrgreater thanResults: Four topics were used by both nurses and physicians in the consultations. These were pathophysiology, diagnostic procedures, treatment and activity. In the nurse-patient consultation an additional topic, routines related to the physicians responsibilities, emerged. With respect to the number of words and turns, the distribution of the discourse space was almost equal between the nurses and patients and unequal between the physicians and patients. The healthcare professionals initiated the topics more frequently compared to the patients, whereby the medical approach recommended in the guidelines for AF could be recognized. The patients were the dominating initiators in the topic activity, which refers to the adaptation of activities in daily life in relation to the AF. less thanbrgreater than less thanbrgreater thanConclusions: The medical-driven agenda dominates over the patient-driven agenda in consultations between healthcare professional and patients with AF. The patients initiated the conversations when discussing living with AF and were more talkative during conversations in nurse consultations.

    Editorial Material: How do we know when patients sleep properly or why they do not?2013In: Critical Care, ISSN 1364-8535, E-ISSN 1466-609X, Vol. 17, no 3Article in journal (Other academic)
    Abstract [en]

    The importance of adequate sleep for good health and immune system function is well documented as is reduced sleep quality experienced by ICU patients. In the previous issue of Critical Care, Elliot and co-workers present a well done, largest of its kind, single-center study on sleep patterns in critically ill patients. They base their study on the gold standard, the polysomnography technique, which is resource demanding to perform and often difficult to evaluate. The results are especially interesting as the authors not only used polysomnography in a large sample but also, in contrast to others, excluded patients with prior sleep problems. They also recorded patients subjective sleep experiences in the ICU and thereafter in the ward (validated questionnaires) with simultaneous data collection of factors known to affect sleep in the ICU (mainly treatment interventions, light and sound disturbances). Interestingly, but not surprisingly, sleep was both quantitatively and qualitatively poor. Furthermore, there seemed to be little or no improvement over time when compared to earlier studies. This study stresses the magnitude of the sleep problem despite interventions such as earplugs and/or eyeshades. Sound disturbance was found to be the most significant but improvable factor. The study highlights the challenge and the importance of evaluating sleep in the critical care setting and the present need for alternative methods to measure it. All that in conjunction can be used to solve an important problem for this patient group.

    Everyday life for the spouses of patients with untreated OSA syndrome2012In: Scandinavian Journal of Caring Sciences, ISSN 0283-9318, E-ISSN 1471-6712, Vol. 26, no 2, p. 324-332Article in journal (Refereed)
    Abstract [en]

    Scand J Caring Sci; 2011 Everyday life for the spouses of patients with untreated OSA syndrome The aim of this study was to generate a theoretical model describing concerns for spouses of patients with untreated obstructive sleep apnoea syndrome (OSAS) and how they manage these concerns in their everyday life. Twelve spouses were interviewed about their experiences and how they manage everyday life. The interviews were analysed according to the Grounded Theory method as described by Strauss and Corbin. Two main categories emerged from the data: 'Social adjustment' and 'New feelings'. 'Social adjustment' reveals how the spouses made adjustments in their daily lives, both according to their partners' tiredness and owing to their own fatigue. 'New feelings' reveals emotional reactions related to the effects of their partner's illness and the impact it had on the spouse's everyday life. These two main categories could be seen in relation to four dimensions describing how the spouses manage their everyday life: 'Sacrificing', 'Controlling', 'Changing' and 'Understanding'. The results show how the spouses made adjustments in everyday life and how their feelings were affected by their partner's OSAS. Healthcare personnel could use information from this study to gain a deeper understanding and knowledge of what spouses of untreated patients with OSAS experience as their main concerns and how they manage their everyday life. This knowledge can be used to improve the support to the spouses, as well as in the educational situation concerning the illness, as well as the treatment.

    Pharmacogenetics, Plasma Concentrations, Clinical Signs and EEG During Propofol Treatment2014In: Basic & Clinical Pharmacology & Toxicology, ISSN 1742-7835, E-ISSN 1742-7843, Vol. 115, no 6, p. 565-570Article in journal (Refereed)
    Abstract [en]

    A variety of techniques have been developed to monitor the depth of anaesthesia. Propofols pharmacokinetics and response vary greatly, which might be explained by genetic polymorphisms. We investigated the impact of genetic variations on dosage, anaesthetic depth and recovery after total intravenous anaesthesia with propofol. A total of 101 patients were enrolled in the study. The plasma concentration of propofol during anaesthesia was measured using high-performance liquid chromatography. EEG was monitored during the surgical procedure as a measure of anaesthetic depth. Pyrosequencing was used to determine genetic polymorphisms in CYP2B6, CYP2C9, the UGTIA9-promotor and the GABRE gene. The correlation between genotype and to plasma concentration at the time of loss of consciousness (LOC), the total induction dose, the time to anaesthesia, eye opening and clearance were investigated. EEG monitoring showed that the majority of the patients had not reached a sufficient level of anaesthetic depth (subdelta) at the time of loss of consciousness despite a high induction dose of propofol. Patients with UGT1A9-331C/T had a higher propofol clearance than those without (p=0.03) and required a higher induction dose (p=0.03). The patients with UGT1A9-1818T/C required a longer time to LOC (p=0.03). The patients with CYP2C9*2 had a higher concentration of propofol at the time of LOC (p=0.02). The polymorphisms in the metabolizing enzymes and the receptor could not explain the large variation seen in the pharmacokinetics of propofol and the clinical response seen. At LOC, the patients showed a large difference in EEG pattern.

    Obstructive sleep apnea: General characteristics in hypertensive patients, positional sensitivity, and upper airway sensory neuropathy2012Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Introduction: Obstructive sleep apnea (OSA) is a highly prevalent disorder, especially in populations with cardiovascular disease. Unfortunately most cases with OSA remain undiagnosed. The ability to identify OSA is important for both the individual and the society, as it is a treatable risk factor for cardiovascular disease and also associated with impaired quality of life. This could be particularly important in populations with cardiovascular disease where the most beneficiary treatment effects could be expected. However, the diagnostic process in OSA may be affected by positional dependency (a majority of OSA patients have more breathing interruptions in supine sleep compared to other sleeping positions). Based on the assumption that individuals have different proportions of supine and non-supine sleep on different nights, positional dependency may be a potential confounder in both diagnosis, classification of OSA severity and evaluation of treatment efficacy. Another aspect of OSA is that the pathogenesis is not fully understood. Data indicate that OSA might be a progressive disease, and many patients report years of snoring before witnessed apneas and symptoms occur. One hypothesis on the pathogenesis of OSA is that long-standing, snoring-induced vibrations cause neurogenic lesions in upper airway tissues, progressively damaging the reflex circuits responsible for keeping the upper airway open during sleep.

    Aims: To describe the occurrence of undiagnosed OSA and to identify determinants of moderate/severe OSA in patients with hypertension (study I). To describe the prevalence of position dependent OSA (POSA) and its relation to OSA severity classification (study II). To compare two methods for quantitative testing of cold sensory function (as a sign of neuropathy) in the upper airway with special focus on test-retest repeatability (study III). To evaluate signs of upper airway sensory neuropathy, by cold sensory testing, in non-snorers, snorers, and snoring OSA subjects with special reference to AHI and duration of snoring history (study IV).

    Methods: In study I 411 consecutive patients with hypertension from four primary care health centers in Sweden were evaluated for OSA as measured by the apnea hypopnea index (AHI) through polygraphic (PG) recordings. Different predictors for moderate/severe OSA were evaluated. In study II the PG recordings of 265 subjects were specially assessed for POSA and the relation between severity classification based on POSA and traditional OSA severity classification. In study III 40 non-snoring subjects were tested for cold detection thresholds at the soft palate and the lip at two separate occasions with two different methods (MLE/MLI). Bland-Altman analysis was used to compare test-retest repeatability. In study IV cold sensory testing of the soft palate and lip was used to evaluate signs of upper airway sensory neuropathy in both non-snorers; snorers, and subjects with OSA (groups were formed based on AHI and snoring history, n=90).

    Results and Conclusions: Undiagnosed OSA is common in Swedish primary care patients with hypertension, and male gender, BMI>30 kg/m2, and a clinical history of snoring and witnessed apneas are predictors of moderate/severe OSA. POSA is common both in subjects that by traditional classification had OSA as well as those without OSA. The severity of OSA, if based on total AHI, could be dependent on supine time in a substantial amount of subjects. Cold sensory testing is easily performed in the oropharynx, with acceptable test–retest repeatability. MLI is considerably faster to perform and have a slightly better repeatability than MLE. Therefore MLI should be the used method for cold thermal testing at the soft palate. Both self-reported snoring years and OSA severity are correlated to the degree of cold sensory impairment in the upper airway. Our results strengthen the hypothesis that snoring vibrations may cause a neuropathy in the upper airway, which may contribute to the progression and development of OSA.

    Objective. In hypertensive primary care patients below 65 years of age, (i) to describe the occurrence of undiagnosed obstructive sleep apnoea (OSA), and (ii) to identify the determinants of moderate/severe OSA. Design. Cross-sectional. Setting. Four primary care health centres in Sweden. Patients. 411 consecutive patients (52% women), mean age 57.9 years (SD 5.9 years), with diagnosed and treated hypertension (BP andgt; 140/90). Main outcome measures. Occurrence of OSA as measured by the apnoea hypopnoea index (AHI). Results. Mild (AHI 5-14.9/h) and moderate/severe (AHI andgt; 15/h) OSA were seen among 29% and 30% of the patients, respectively. Comparing those without OSA with those with mild or moderate/severe OSA, no differences were found in blood pressure, pharmacological treatment (anti-hypertensive, anti-depressive, and hypnotics), sleep, insomnia symptoms, daytime sleepiness, or depressive symptoms. Obesity (BMI andgt; 30 kg/m(2)) was seen in 30% and 68% of the patients with mild and moderate/severe OSA, respectively. Male gender, BMI andgt; 30 kg/m(2), snoring, witnessed apnoeas, and sleep duration andgt; 8 hours were determinants of obstructive sleep apnoea. Conclusion. Previously undiagnosed OSA is common among patients with hypertension in primary care. Obesity, snoring, witnessed apnoeas, long sleep duration, and male gender were the best predictors of OSA, even in the absence of daytime sleepiness and depressive symptoms.

    Abstract [en]

    Purpose: The apnea–hypopnea index (AHI) is used to grade obstructive sleep apnea (OSA) into mild, moderate, and severe forms. Obstructive events are most common in the supine position. The amount of supine sleep thus influences total AHI. Our aim was to determine the prevalence of position-dependent OSA (POSA) and its relation to OSA severity classification as recommended by the American Academy of Sleep Medicine (AASM).

    Methods: Two hundred sixty-five subjects were recruited from primary care hypertension clinics. Whole-night respiratory recordings were performed to determine the AHI in the supine and non-supine positions, respectively. POSA was defined as supine AHI twice the non-supine AHI with supine AHI ≥5.

    Results: Fifty-three percent had POSA, 22% had non-position-dependent OSA, and 25% had normal respiration. By AASM classification, 81 subjects did not have OSA, but 42% of them had some degree of obstruction when supine, and 5 subjects would have been classified as moderate–severe if they had only slept supine. Conversely, of the 53 classified as mild OSA, 30% would have changed to a more severe classification if they had exclusively slept supine.

    Conclusions: POSA was common both in subjects that by AASM classification had OSA as well as those without. The severity of OSA, as defined by AASM, could be dependent on supine time in a substantial amount of subjects

    Abstract [en]

    Objective: Several studies indicate an upper airway peripheral neuropathy in obstructive sleep apnea syndrome (OSAS). The sensation of cold, as measured by cold detection thresholds (CDT), in the oropharynx has been shown to be compromised in patients with sleep apnea and, to a lesser extent, habitual snoring. To reveal whether this neuropathy is part of the pathogenetic process of OSAS, longitudinal studies of snorers are needed. The objective of the present study was to establish the test-retest repeatability for the two most commonly used thermal testing methods: the reaction time exclusive method of levels (MLE) and the method of limits (MLI). Methods: Forty non-snoring subjects were tested at the soft palate and the lip at two separate occasions (mean interval 45 days) using a Medoc TSA - 2001 equipment with an intra-oral thermode. Results: With MLE mean CDTs were lower for both the lip and soft palate than with MLI. However, MLI showed a better test-retest repeatability (r = 2.2 vs. 2.6) for the soft palate. Conclusions: MLI should be used in longitudinal studies. The performance of this method is also faster. Significance: We have established a quick, safe and reliable method suitable for longitudinal studies of peripheral neuropathy in sleep apnea pathogenesis.

    Abstract [en]

    Objectives/Hypothesis: In general, obstructive sleep apnea (USA) seems to be a progressive disorder whose pathogenesis is not fully understood. One hypothesis is that long-standing snoring vibrations cause a local neuropathy in the upper airway, which predisposes to obstructive events during sleep. The aim of this study was to investigate sensory function in the upper airway in a cohort of subjects comprising nonsnorers, snorers, and untreated subjects with USA, and to correlate data to apnea-hypopnea index (AHI) and duration of snoring. Study Design: Cross-sectional cohort study. Methods: Subjects were recruited from primary care hypertension clinics. Whole-night respiratory recordings were performed to determine presence and degree of USA. Three groups were formed based on AHI and snoring history: 1) nonsnorers (n = 25); 2) snorers, AHI andlt; 10 (n = 32); 3) USA subjects, AHI andgt;= 10 (n = 33). Quantitative cold sensory testing of the soft palate and lip was used to assess neuropathy. Results: There were no significant differences concerning lip sensory function between groups. Nonsnorers showed significantly lower thresholds for cold (i.e., better sensitivity) in the soft palate compared to both other groups (P andlt; .01). Snorers had lower thresholds than USA subjects (P andlt; .05). There were significant correlations (P andlt; .01) between decreased sensory function and AHI (r(s) = .41) and to duration of snoring (r(s) = .47). Conclusions: The degree of sensory neuropathy in the upper airway correlates with degree of obstructive sleep disorder. Our results strengthen the hypothesis that snoring vibrations may cause a neuropathy in the upper airway, which contributes to the progression and development of USA.

    Psychometric aspects of obstructive sleep apnea syndrome2013Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Introduction: Obstructive sleep apnea (OSA) is a common chronic disorder consisting of episodes with impaired breathing due to obstruction of the upper airways. Treatment with Continuous Positive Airway Pressure (CPAP) is a potentially effective treatment, but adherence is low. Several potential factors affecting adherence, e.g., subjective sleepiness and personality, are only quantifiable through questionnaires. Better knowledge about psychometric properties of such questionnaires might improve future research on CPAP adherence and thus lead to better treatment options.

    Aim: Study I: To describe the devlopment and initial testing of the Side Effects of CPAP treatment Inventory (SECI) questionnaire. Study II: To describe the prevalence of Type D personality in OSAS patients with CPAP treatment longer than 6 months and the association with self-reported side effects and adherence. Study III: To study whether any of the items in the Epworth Sleepiness Scale (ESS) exhibit differential item functioning and, if so, to which degree. Study IV: To examine the evolution of CPAP side effects over time; and prospectively assess correlations between early CPAP side effects and treatment adherence.

    Patients and Methods: In study I, SECI items were based on a literature review, an expert panel and interviews with patients. It was then mailed to 329 CPAP-treated OSAS patients. Based on this, a principal component analysis was performed, and SECI results were compared between adherent and non-adherent patients. In study II, the population consisted of 247 OSAS patients with ongoing CPAP treatment. The DS14 was used to assess the prevalence of type D personality, and SECI and adherence data from medical records were used to correlate Type D personality to side effects and adherence. In study III, the population consisted of pooled data from 1,167 subjects who had completed the ESS in five other studies. Ordinal regression and Rasch analysis were used to assess the existence of differential item functioning for age and gender. The cutoff for age was 65 years in the Rasch analysis. In study IV, SECI was sent to 186 subjects with newly diagnosed OSAS three times during the first year on CPAP. SECI results were followed over time within subjects, and were correlated to treatment dropout during the first year and machine usage time after 6 months.

    Results: SECI provides a valid and reliable instrument to measure side effects, and non-adherent patients have higher scores (i.e., were more bothered by side effects) than adherent patients (study I). Type D personality was prevalent in approximately 30 % of CPAP treated OSAS patients, and was associated to poorer objective and subjective adherence as well as more side effects (study II). Differential item functioning was present in items 3, 4 and 8 for age in both DIF analyses, and to gender in item 8 the Rasch analysis (study III). Dry mouth and increased number of awakenings were consistently associated to poorer adherence in CPAP treated patients. Side effects both emerged and resolved over time (study IV).

    Conclusions: Differences in previous research regarding side effects and CPAP adherence might be explained by differences in how side effects and adherence are defined. While some side effects are related to adherence, others are not. Side effects are furthermore not stable over time, and might be related to personality. ESS scores are also related to CPAP adherence according to previous research, but might be affected by other factors than sleepiness, such as age and possibly gender.

    Abstract [en]

    Continuous positive airway pressure (CPAP) is the treatment of choice for obstructive sleep apnoea syndrome (OSAS), but side-effects are common. No validated self-rating scale measuring side-effects to CPAP treatment exists today. The aim was to develop the side-effects to CPAP treatment inventory (SECI), and investigate the validity and reliability of the instrument among patients with OSAS. SECI was developed on the basis of: (1) in-depth interviews with 23 patients; (2) examination of the scientific literature and (3) consensus agreement of a multi-professional expert panel. This yielded 15 different types of side-effects related to CPAP treatment. Each side-effect has three sub-questions (scales): perceived frequency (a) and magnitude (b) of the side-effect, as well as its perceived impact on CPAP use (c). A cross-sectional descriptive design was used. A total of 329 patients with OSAS with an average use of CPAP treatment for 39 months (2 weeks to 182 months) were recruited. Data were collected with SECI, and obtained from medical records (clinical variables and data related to CPAP treatment). Construct validity was confirmed with factor analysis (principal component analysis with orthogonal rotation). A logical two-factor solution, the device subscale and symptom subscale, emerged across all three scales. The symptom subscale describing physical and psychological side-effects and the device subscale described mask and device-related side-effects. Internal consistency reliability of the three scales was good (Cronbach’s α = 0.74–0.86) and acceptable for the subscales (Cronbach’s α = 0.62–0.86). The satisfactory measurement properties of this new instrument are promising and indicate that SECI can be used to measure side-effects to CPAP treatment.

    Abstract [en]

    Continuous positive airway pressure (CPAP) is the treatment of choice for obstructive sleep apnoea syndrome (OSAS), but side effects are common and long-term adherence low. The Type D (distressed) personality is defined as a combination of negative affectivity and social inhibition. The association of Type D personality with adherence has not been studied in CPAP-treated patients with OSAS. This study aimed to describe the prevalence of Type D personality in OSAS patients with CPAP treatment longer than 6 months and the association with self-reported side effects and adherence. A cross-sectional descriptive design was used. A total of 247 OSAS patients with a mean use of CPAP treatment for 55 months (6-182 months) were included. Data collection was achieved by two questionnaires, the Type D scale 14 (DS14) (Type D personality), SECI (side effects of CPAP), as well as from medical records (clinical variables and objective adherence to CPAP treatment). Type D personality occurred in 30% of the patients with OSAS and significantly (P < 0.05-0.001) increased the perceived frequency and severity of a broad range of side effects. The objective adherence was significantly lower (P < 0.001) for OSAS patients with Type D compared to OSAS patients without Type D, both with regard to a mean use of 4 h per night and 85% of the self-rated sleep time per night. The additional effect of a Type D personality on perceived side effects and adherence to CPAP treatment found in this study could be used by healthcare personnel when evaluating patients waiting for treatment. © 2007 European Sleep Research Society.

    Abstract [en]

    Purpose

    Differential item functioning (DIF) is said to exist in an item if a subject’s response to the item is affected by other aspects than that which the test is intended to assess. DIF might affect the validity of a test. The aim of this study was thus to examine whether any of the items in the Epworth Sleepiness Scale (ESS) exhibits DIF regarding age or gender, and if so, to which degree.

    Methods

    Using previously collected cross-sectional ESS data from 1,168 subjects with different clinical characteristics (61% males, mean age 67.8 year (SD 12.2 year)), ordinal regression as well as Rasch-based DIF analyses were performed.

    Results

    Concerning age, both DIF analyses showed DIF for age in items 3 (inactive in a public place), 4 (passenger in a car), and 8 (in a car that has stopped in traffic). The Rasch model also showed DIF for gender in item 3. The DIF magnitudes as judged by McFadden pseudo-R2 changes were, however, only minor.

    Conclusions

    ESS has small but reproducible DIF for age in items 3, 4, and 8. The detected DIF might be worth to consider in large-sample studies, although it probably has no effect on an individual basis.

    Abstract [en]

    Purpose: Continuous Positive Airway Pressure is an effective treatment for obstructive sleep apnea, but adherence is often low and side effects are common. It is unclear from previous research whether side effects are significant causes of non-adherence. No study has examined if side effects vary within subjects over time. The aims were to 1) examine the evolution of CPAP side effects over time; and 2) prospectively assess correlations  between early CPAP side effects and treatment adherence. Methods: 186 obstructive sleep apnea patients from three sleep centres were prospectively enrolled. They completed the Side Effects to CPAP Inventory, where the respondent rates the frequency, magnitude and perceived impact on adherence from 15 side effects. Adherence was measured by treatment dropout and machine usage time. Results: The most common side effects were dry mouth, increased number of awakenings, blocked up nose, mask pressure and mask leaks. While some side effects were stable over time, others could both resolve and emerge within subjects. Dry mouth, mask leakage and blocked up nose emerged within one year in approximately 30% of patients who had not experienced them after two weeks. Increased number of awakenings and dry mouth after 1-2 weeks were significantly associated to treatment dropout during the first year and machine usage time after six months. Conclusions: While some side effects are related to adherence, most are not. Not all side effects are stable over time. This, together with differences in methodology between studies, might explain the conflicting findings in earlier research.

    The fairness of the Epworth Sleepiness Scale: two approaches to differential item functioning2013In: Sleep and Breathing, ISSN 1520-9512, E-ISSN 1522-1709, Vol. 17, no 1, p. 157-165Article in journal (Refereed)
    Abstract [en]

    Purpose

    Differential item functioning (DIF) is said to exist in an item if a subject’s response to the item is affected by other aspects than that which the test is intended to assess. DIF might affect the validity of a test. The aim of this study was thus to examine whether any of the items in the Epworth Sleepiness Scale (ESS) exhibits DIF regarding age or gender, and if so, to which degree.

    Methods

    Using previously collected cross-sectional ESS data from 1,168 subjects with different clinical characteristics (61% males, mean age 67.8 year (SD 12.2 year)), ordinal regression as well as Rasch-based DIF analyses were performed.

    Results

    Concerning age, both DIF analyses showed DIF for age in items 3 (inactive in a public place), 4 (passenger in a car), and 8 (in a car that has stopped in traffic). The Rasch model also showed DIF for gender in item 3. The DIF magnitudes as judged by McFadden pseudo-R2 changes were, however, only minor.

    Conclusions

    ESS has small but reproducible DIF for age in items 3, 4, and 8. The detected DIF might be worth to consider in large-sample studies, although it probably has no effect on an individual basis.
