Predictors of retention in heroin-assisted treatment in Denmark 2010-2018 - A record-linkage study

INTRODUCTION

While randomized-controlled trials have shown that heroin-assisted treatment (HAT) is superior to methadone maintenance alone in treatment of refractory clients, little is known about client factors associated with retention in HAT in routine care.

METHODS

This retrospective cohort study assessed predictors of retention in first treatment episode among a consecutive cohort of clients admitted to HAT in Denmark from 2010 to 2018, who could be matched to the Danish population register and for whom a Short Form Health Survey (SF-36) was available at admission (N = 432). The study derived predictors from client self-reports at intake and administrative data available in national registers. Cox proportional hazards regression modelled retention in treatment.

RESULTS

The one-year retention rate was 69.63 % (95 % CI 65.06 %-73.74 %), and the median time in treatment was 2.45 years (95 % CI, 1.83-3.12). Bivariate analyses showed that retention was lower for clients who had recent cocaine or benzodiazepine use and among those who had experienced an overdose in the year prior to enrollment in HAT. Age below 40, recent illegal activity, poorer emotional wellbeing, previous residential treatment experience, and previous intensive outpatient treatment were also predictors of dropout from HAT.

CONCLUSIONS

This observational study found that retention in HAT in routine care was similar to rates observed in randomized-controlled trials conducted in other countries. The results suggest that addressing polysubstance use as part of the HAT program may promote long-term retention, as may directing resources to certain subgroups identified at intake, including clients under 40 years and those who report recent criminal activity, emotional problems, or overdoses. The findings that previous residential treatment and intensive outpatient treatment were associated with dropout were unexpected.

Feasibility of a home-based exercise intervention for patients with systemic sclerosis

INTRODUCTION

Systemic sclerosis (SSc) is a rare connective tissue disease causing pain, reduced mobility and decreased health-related quality of life (HRQoL). Studies suggest that exercise is a necessary adjunct to the medical treatment.

PURPOSE

To examine the feasibility of a 12-week home-based exercise program for SSc patients, and evaluate changes in physical function, HRQoL and SSc-related symptoms.

METHODS

Twenty patients were enrolled in the study. Feasibility was measured by adherence, adverse events, and exercise task self-efficacy. At baseline and follow-up patients completed the 6-minute walk test, 30-second sit-to-stand test, 30-second arm curl, SSc Impact of Disease (ScleroID) and 36-item short form survey (SF-36).

RESULTS

Median adherence to the intervention was 36 (interquartile range 27-36) out of a total of 36 exercise sessions. Fifteen patients completed the intervention, with three dropouts. Patients' exercise task self-efficacy was 98%, 93% and 78%, for one, two and three weekly exercise sessions, respectively. There were no adverse events related to the exercise sessions. Improvements were observed in all physical tests, and minor improvements in HRQoL and SSc-related symptoms.

CONCLUSION

This study suggests that a home-based exercise intervention is feasible for patients with SSc. The results suggest improvements in physical function, HRQoL and SSc-related symptoms.

Autologous Fat Grafting Is Not Superior to Placebo as Treatment of Postherpetic Neuralgia: A Double-Blind Randomized Clinical Trial

BACKGROUND

Postherpetic neuralgia (PHN) is a chronic pain syndrome occurring after a herpes zoster outbreak. While there is no effective treatment available today, autologous fat grafting has shown promise. This randomized controlled trial investigated the effectiveness of fat grafting as treatment for PHN compared with a sham treatment.

METHODS

A total of 46 participants with PHN were included. After liposuction under general anesthesia, participants were randomly assigned to receive either autologous fat grafting or saline injection to the area of pain. The primary outcomes were the average and maximum degree of pain measured on an 11-point numeric rating scale. Secondary outcomes were quality and degree of neuropathic pain (Neuropathic Pain Symptom Inventory) and quality of life (36-Item Short-Form Health Survey).

RESULTS

Forty-two participants completed follow-up of 6 months. For maximal degree of pain, a reduction of -1.1 ± 0.6 and -1.0 ± 0.5 mean change (±SE) on the numeric rating scale was observed in the intervention and control groups, respectively. For average degree of pain, the reduction was -1.2 ± 0.5 and -1.3 ± 0.4 in the intervention and control groups, respectively. The authors did not observe any significant changes in the neuropathic pain and quality-of-life parameters. For all measured outcomes, the differences between the groups were not statistically significant.

CONCLUSIONS

The authors did not find autologous fat grafting superior to a placebo when treating PHN of the skin. Given their results, they cannot recommend the routine use of this method to treat these pains.

CLINICAL RELEVANCE STATEMENT

Since autologous fat grafting was not proven to be more effective than a placebo in treating PHN, alternative treatment options should be explored. It is also essential to emphasize the importance of prophylactic vaccination against herpes zoster.

Patient-reported outcome measures as determinants for the utilization of health care among outpatients with epilepsy: a prognostic cohort study

BACKGROUND

Patient-reported outcome (PRO) measures can inform clinical decision making and planning of treatment in the health care system. The aim of this study was to examine whether patient-reported health domains influence the use of health care services in outpatients with epilepsy.

METHODS

This was a prognostic cohort study of 2,426 epilepsy outpatients referred to PRO-based follow-up at the Department of Neurology, Aarhus University Hospital, Denmark. Patients filled out a questionnaire covering health literacy areas, self-efficacy, well-being and general health. The main outcome was a record of contact to the epilepsy outpatient clinic, inpatient ward and/or emergency room within 1 year, retrieved from health register data. Associations were analysed by multivariable binomial logistic regression.

RESULTS

A total of 2,017 patients responded to the questionnaire and 1,961 were included in the final analyses. An outpatient contact was more likely among patients with very low health literacy ('social support'): odds ratio (OR) 1.5 (95% CI: 1.1-2.1), very low and low self-efficacy: OR 1.7 (95% CI: 1.2-2.3) and OR 1.4 (95% CI: 1.0-1.8), low and medium well-being: OR 2.2 (95% CI: 1.6-3.0) and OR 1.4 (95% CI: 1.1-1.9), and patients rating their general health as fair: OR 2.8 (95% CI: 1.7-4.6). Inpatient contact and emergency room contact were associated with the health domains of self-efficacy and general health.

CONCLUSIONS

PRO questionnaire data indicated that patients with low health literacy ("social support"), well-being, self-efficacy and self-rated general health had an increased use of health care services at 1 year.These results suggest that PRO measures may provide useful information in relation to the possibility of proactive efforts and prevention of disease-related issues and to help identify efficiency options regarding resource utilization.

Clinical Impact of Systematic Assessment and Psychoeducation in Specialized Treatment of Adolescents with Severe Functional Somatic Disorders: Results from the AHEAD Study

Functional somatic disorders (FSD), characterized by persistent and disabling physical symptoms, are common in adolescents. Diagnostic uncertainty and insufficient illness explanations are proposed perpetuating factors that may constitute barriers for treatment engagement. This study describes the impact of manualized assessment and psychoeducation on diagnostic certainty and various clinical outcomes in adolescents with multi-system FSD. Ninety-one adolescents (15-19 years) received systematic assessment (4 h) and a subsequent psychiatric consultation (1.5 h). Clinical characteristics included self-reported physical health, symptom severity, illness perception, illness-related behavior, and psychological flexibility assessed before and approximately two months after assessment, prior to specialized treatment. Data were analyzed using t-tests. Immediately following assessment, 71 (80.7%) adolescents out of 88 reported a higher diagnostic certainty and 74 (84.1%) reported that attending assessment gave them positive expectations for future treatment. A clinically relevant improvement of physical health was not observed at two months but considerable reductions were seen in symptom severity, illness worry, negative illness perceptions, illness-related limiting behavior, and psychological inflexibility. The results emphasize that systematic assessment and psychoeducation are important in their own right in the specialized treatment of adolescents with severe FSD.

Quality of life of pediatric and adult individuals with osteogenesis imperfecta: a meta-analysis

BACKGROUND

Osteogenesis imperfecta (OI) is a group of rare inheritable disorders of connective tissue. The cardinal manifestations of OI are low bone mass and reduced bone mineral strength, leading to increased bone fragility and deformity that may lead to significant impairment in daily life. The phenotypic manifestations show a broad range of severity, ranging from mild or moderate to severe and lethal. The here presented meta-analysis aimed to analyze existing findings on quality of life (QoL) in children and adults with OI.

METHODS

Nine databases were searched with predefined key words. The selection process was executed by two independent reviewers and was based on predetermined exclusion and inclusion criteria. The quality of each study was assessed using a risk of bias tool. Effect sizes were calculated as standardized mean differences. Between-study heterogeneity was calculated with the I² statistic.

RESULTS

Among the studies included two featured children and adolescents (N = 189), and four adults (N = 760). Children with OI had significantly lower QoL on the Pediatric quality of life inventory (PedsQL) with regards to the total score, emotional, school, and social functioning compared to controls and norms. The data was not sufficient to calculate differences regarding OI-subtypes. In the adult sample assessed with Short Form Health Survey Questionnaire, 12 (SF-12) and 36 items (SF-36), all OI types showed significantly lower QoL levels across all physical component subscales compared to norms. The same pattern was found for the mental component subscales namely vitality, social functioning, and emotional role functioning. The mental health subscale was significantly lower for OI type I, but not for type III and IV. All of the included studies exhibited a low risk of bias.

CONCLUSIONS

QoL was significantly lower in children and adults with OI compared to norms and controls. Studies in adults comparing OI subtypes showed that the clinical severity of the phenotype is not related to worse mental health QoL. Future research is needed to examine QoL in children and adolescents in more sophisticated ways and to better understand the association between clinical severity of an OI-phenotype/severity and mental health in adults.

Internet-delivered treatment for patients suffering from severe functional somatic disorders: Protocol for a randomized controlled trial

Background

Functional somatic disorders (FSDs) with symptoms from multiple organs, i.e., multi-system type, are common in the general population and may lead to disability and reduced quality of life. Evidence for efficient treatment programs has been established, however, there is a need for making treatments accessible to a larger group of patients. Internet-delivered therapy has become prevalent and has proven as effective as face-to-face therapy, while providing a flexible and easily accessible treatment alternative. The aim of the current study is to compare the efficacy of the therapist-assisted internet-delivered treatment program One step at a time (OneStep) with the internet-delivered self-help program Get started (GetStarted).

Methods

A total of 166 participants aged 18-60 years diagnosed with multi-system FSD will be assessed and randomized to either 1) OneStep: a 14-week program consisting of 11 treatment modules based on principles from cognitive behavioural therapy or 2) GetStarted consisting of 1 module on psychoeducation. The primary outcome is physical health, assessed by a Short Form Health Survey (SF-36) aggregate score of the subscales vitality, physical functioning, and bodily pain 3 months after end-of-treatment and self-reported improvement assessed by the Clinical Global Improvement Scale. Secondary outcomes include symptom load, depression, anxiety, and illness worry. Process measures include emotional distress, illness perception, illness behaviour, and symptom interference.

Conclusions

This study is the first study to test an internet-delivered treatment program for FSD, multi-system type and has the potential to show the importance of making evidence-based internet-delivered treatment for FSD more accessible.

Prevalence of chronic pain in a national cohort of patients with limb-girdle muscular dystrophy: a cross-sectional study

PURPOSE

The aim was to investigate the prevalence, characteristics, predictors, and consequences of chronic pain in a national cohort of patients with limb-girdle muscular dystrophy (LGMD).

MATERIALS AND METHODS

Questionnaires were sent to all Danish LGMD patients (≥18 years of age) registered with the National Rehabilitation Center for Neuromuscular Diseases.

RESULTS

Of 209 patients, 121 responded. 44.7% of the patients experienced persistent (daily or constant) chronic pain lasting more than 3 months. 21.0% of patients experienced chronic pain that was not daily. Most pain patients experienced three or more pain problems, primarily in the lower back, neck, shoulders, hips, and legs. Symptoms suggestive of neuropathic pain were sometimes present. Patients with persistent chronic pain reported moderate pain interference with daily activities, greater psychological distress, and lower quality of life compared to patients without pain but did not differ regarding physical functioning. Sex, age, LGMD duration, LGMD type, mechanical ventilation use, mobility, arm function, or performance on activities of daily living did not predict chronic pain.

CONCLUSION

Chronic pain is common in patients with LGMD. Chronic pain should be considered an important component of LGMD and addressed in the clinic and rehabilitation setting from a biopsychosocial perspective.Implication for rehabilitationChronic pain is highly prevalent in patients with limb-girdle muscular dystrophy.Health professionals need to systematically ask patients about pain and the influence of pain on everyday life irrespective of LGMD-duration and extent of muscle wastage.Chronic pain and psychological distress need to be addressed in the clinic and rehabilitation setting as an additional disabling component of LGMD and this should be done within a biopsychosocial framework.

Test–retest reliability and measurement error of the WHO-5 Well-being Index and the Problem Areas in Diabetes questionnaire (PAID) used in telehealth among patients with type 1 diabetes

Background

Patient-reported outcome (PRO) measures may be used in telehealth for the clinical assessment of mental health and diabetes distress, which are important aspects in diabetes care, but valid and reliable instruments on these topics are necessary. We aimed to evaluate the test–retest reliability and measurement error of the Danish versions of the WHO-Five Well-being Index (WHO-5) and Problem Areas in Diabetes (PAID) questionnaires used in a PRO-based telehealth intervention among patients with type 1 diabetes. A further aim was to evaluate the test–retest reliability of single items concerning patients’ symptom burden and general health status.

Methods

Outpatients with type 1 diabetes from the Steno Diabetes Center Aarhus, Aarhus University Hospital, Denmark, were enrolled from April 2019 to June 2020. Patients aged ≥ 18 who had type 1 diabetes for > 1 year, internet access, and the ability to understand, read, and write Danish were included. Intraclass correlation coefficients (ICC) and weighted Kappa values were used to assess test–retest reliability, and measurement error was assessed by estimating the minimal detectable change (MDC).

Results

A total of 146/255 (57%) patients completed the web questionnaire twice. The median response time between the two-time points was five days. The ICC of the WHO-5 scale was 0.87 (95% CI 0.82–0.90), and MDC was 18.56 points (95% CI 16.65–20.99). The ICC of the PAID scale was 0.89 (95% CI 0.84–0.92), and MDC was 11.86 points (95% CI 10.46–13.70). Overall, test–retest reliability of single symptoms and general health status items was substantial.

Conclusions

The WHO-5 and PAID questionnaires, and single symptoms and general health status items showed substantial test–retest reliability among patients with type 1 diabetes. Measurement error of the PAID questionnaire was considered acceptable; however, a larger measurement error of the WHO-5 questionnaire was observed. Further research is recommended to explore these findings.

Randomized controlled trial of Tesomet for weight loss in hypothalamic obesity

CONTEXT

Hypothalamic injury often leads to rapid, intractable weight gain causing hypothalamic obesity, which is associated with increased risk of cardiovascular and metabolic morbidity and mortality. There are no approved or effective pharmacological treatments for hypothalamic obesity, and conventional lifestyle management remains ineffective.

OBJECTIVE

To investigate the safety and efficacy of Tesomet (0.5 mg tesofensine/50 mg metoprolol) in adults with hypothalamic obesity.

METHODS

Twenty-one adults with hypothalamic obesity (16 females) were randomized to Tesomet (0.5 mg/50 mg) or placebo for 24 weeks. Patients also received diet/lifestyle counselling. The primary endpoint was safety; secondary endpoints included measures of body weight, appetite scores, quality of life, and metabolic profile.

RESULTS

Eighteen patients completed 24 weeks. Consent withdrawal, eligibility, and serious adverse events (SAE) unrelated to treatment resulted in dropouts. One patient experienced a Tesomet-related SAE of exacerbated pre-existing anxiety leading to treatment discontinuation. Tesomet-related adverse events were otherwise mostly mild and included sleep disturbances (Tesomet 50%, placebo 13%), dry mouth (Tesomet 43%, placebo 0%), and headache (Tesomet 36%, placebo 0%). No significant differences in heart rate or blood pressure were observed between groups. Compared to placebo, Tesomet resulted in additional mean (95% CI) weight change of -6.3% ((-11.3; -1.3); P = 0.017), increased the number of patients achieving ≥5% weight loss (Tesomet 8/13, placebo 1/8; P = 0.046), and tended to augment the reduction in waist circumference by 5.7 cm ((-0.1; 11.5); P = 0.054).

CONCLUSION

Tesomet was welltolerated, did not affect heart rate or blood pressure, and resulted in significant reductions in body weight compared to placebo in adults with hypothalamic obesity.

The effect of gluten in adolescents and young adults with gastrointestinal symptoms: a blinded randomised cross-over trial

BACKGROUND

The popularity of the gluten-free diet and sales of gluten-free products have increased immensely.

AIMS

To investigate whether gluten induces gastrointestinal symptoms, measured by self-reported questionnaires, as well as mental health symptoms in adolescents from a population-based cohort.

METHODS

The eligible participants (n = 273) were recruited from a population-based cohort of 1266 adolescents and had at least four different gastrointestinal symptoms. Phase one (n = 54) was a run-in phase where the participants lived gluten-free for 2 weeks. If they improved they continued to phase 2 (n = 33), a blinded randomised cross-over trial. Participants were blindly randomised either to start with 7 days of gluten, eating two granola bars containing 10 g of gluten or to 7 days on placebo, eating two granola bars without gluten, followed by the reverse and separated by a 7-day washout period. The effects of the intervention on gastrointestinal symptoms and mental health symptoms were assessed.

RESULTS

In total, 54/273 participants entered the run-in phase and 35 were eligible for randomization. A total of 33 were randomised and 32 completed the trial. The median age was 20.3 (IQR 19.2-20.9) and 32/33 participants were females. Compared with a placebo, gluten did not induce gastrointestinal symptoms. The difference in the average VAS was -0.01 (95% confidence interval -2.07 to 2.05). Nor did we find a difference in the outcomes measuring mental health.

CONCLUSION

Compared with placebo, adding gluten to the diet did not induce gastrointestinal symptoms or worsened mental health in adolescents recruited from a population-based cohort. The trial registration number is NCT04639921.

Parked on the verge: vocational rehabilitation of long-term unemployed citizens - a mixed methods study

BACKGROUND

Vocational rehabilitation programs (VRP) developing and improving work ability are used in Denmark to assist long-term unemployed citizens with complex problems. The aims of this study were to (1) describe VRP-participants in relation to general health, well-being, work ability and self-efficacy at baseline and one-year follow-up, (2) obtain an understanding of VRP-participants' personal development towards improving work ability, and (3) explore VRP-participants' hopes and thoughts about their future.

METHODS

In a mixed methods approach, data from a longitudinal survey and semi-structured interviews were collected. In the quantitative longitudinal survey, all participants completed paper questionnaires at baseline and one-year follow-up. For the qualitative semi-structured interviews, VRP participants were recruited with a maximum variation sampling strategy through VRP coordinators and personal contact. Data were analysed by descriptive statistics and systematic text condensation. Following analysis, data were merged and presented in combination according to identified themes.

RESULTS

At baseline and one-year follow-up 146 (response rate 34%) and 74 participants (response rate 52%) respectively, responded to the questionnaire. Seven participants were interviewed. The analysis revealed four themes: 1) Individual explanations of life situation and health; 2) Finding the path; 3) Work as giving meaning to life; 4) Hope for the future. Despite self-reported scores indicating poor general health, lack of well-being, low work ability and low self-efficacy, VRP-activities seemed to have assisted participants in finding meaning in life. VRP-components that may be drivers of successful recovery processes were identified.

CONCLUSIONS

VRP-participants experienced life situations that include multifactorial burdens, and low levels of general health, well-being, work ability, and self-efficacy at baseline and 1 year later. From the outset, most did not have a clear goal of employment, but over time, new goals were set as realistic opportunities for re-developing their work ability were explored. Successful core components of VRP were individually tailored programs and support, development of new relationships, and accommodated flexible internships and jobs.

Autologous Fat Grafting as Treatment of Postmastectomy Pain Syndrome: A Randomized Controlled Trial

BACKGROUND

Postmastectomy pain syndrome is a common and disabling side effect of breast cancer treatment. Medical treatment seems to be insufficient for a considerable proportion of patients. Fat grafting has shown promise in relieving pain from postmastectomy pain syndrome, but no randomized clinical trial comparing fat grafting to a sham operation has been performed to date. The authors' objective was to compare the effect of fat grafting compared to a sham operation for treating postmastectomy pain syndrome.

METHODS

The authors conducted a single-center, double-blind, randomized clinical trial with two arms between October of 2017 and September of 2020. The authors assessed four patients suffering from postmastectomy pain syndrome for inclusion. The intervention group received scar-releasing rigottomy and fat grafting to the area of pain. The control group received scar-releasing rigottomy and a placebo of saline solution. The primary outcome was the degree of pain measured using the Numerical Rating Scale. The secondary outcomes were the degree and quality of neuropathic pain (Neuropathic Pain Symptom Inventory) and quality of life (36-Item Short-Form Health Survey). Follow-up was 6 months.

RESULTS

Thirty-five participants completed follow-up: 18 participants in the intervention group and 17 in the control group. The authors detected no statistically significant changes in average and maximum pain or neuropathic pain. Regarding quality of life, the control group reported a statistically significant improvement in emotional problem parameters, whereas the intervention group reported a deterioration. The authors observed no serious adverse effects.

CONCLUSION

The authors did not find evidence to support that fat grafting is superior to a placebo when treating postmastectomy pain syndrome.

Acupuncture (superficial dry-needling) as a treatment for chronic postherpetic neuralgia - a randomized clinical trial

BACKGROUND

Postherpetic neuralgia is a painful condition where finding sufficient treatment poses a great challenge. Acupuncture is often used as an alternative treatment for these pains, yet no randomized trials, using a sham-placebo have been performed to confirm its effect. Our objective was to investigate the efficacy of acupuncture compared to sham-acupuncture when treating chronic postherpetic dermal pain.

METHODS

We performed a sham-controlled double-blinded randomized clinical trial (RCT) with two arms. The intervention group received superficial dry-needling, and the control group received sham acupuncture using blunted needles. Twenty-six patients received two treatments. They filled out questionnaires at baseline and 1 month after treatment: (1) average and maximum pain (Numeric Rating Scale), (2) neuropathic pain (Neuropathic Pain Scale Inventory) and (3) Quality of Life (QoL) (Short-form 36).

RESULTS

Thirteen patients were allocated to the intervention group and 15 to the control group. We did not detect any significant changes in levels of pain and neuropathic pain. One QoL parameter, regarding emotional problems, reached a level of statistical significance. The sham-blinding was successful. This is the first RCT on the effect of acupuncture (superficial dry-needling) on postherpetic neuralgia (PHN), using a sham procedure as control. We observed no significant changes or tendencies in the measured levels of pain. One QoL parameter had significant improvement in the intervention group compared to the control group.

CONCLUSION

In conclusion, acupuncture was not superior to treatment with sham acupuncture. Though individual patients may experience some pain relief from acupuncture, our results do not support the routine use of this type of acupuncture to treat PHN.

Prospective associations between alcohol consumption and psychological well-being in midlife

BACKGROUND

Alcohol consumption potentially influences psychological well-being in beneficial and harmful ways, but prospective studies on the association show mixed results. Our main purpose was to examine prospective associations between alcohol consumption and psychological well-being in middle-aged men and women.

METHODS

The study sample included 4148 middle-aged individuals (80% men) from the Copenhagen Aging and Midlife Biobank who reported their alcohol consumption (average weekly consumption and frequency of binge drinking) at baseline in 2004 or 2006 and reported their psychological well-being (satisfaction with life and vitality) at follow-up in 2009-2011. Analyses were adjusted for sociodemographic factors, lifestyle, social relations, and morbidity.

RESULTS

For satisfaction with life at follow-up, lower scores were observed in men and women who were alcohol abstinent at baseline as well as in men with heavy alcohol consumption compared with moderate alcohol consumption at baseline. Moreover, men with weekly binge drinking at baseline had lower satisfaction with life scores at follow-up than men with moderate frequency of binge drinking (1-3 times/month). In relation to vitality at follow-up, alcohol abstinence at baseline in men and women and heavy alcohol consumption at baseline in men were associated with lower scores compared with moderate alcohol consumption (yet in men these findings were not robust to adjustment for covariates).

CONCLUSIONS

Alcohol abstinence seems to be prospectively associated with adverse psychological well-being (vitality and life satisfaction) in men and women, while heavy alcohol consumption seems to be prospectively associated with adverse satisfaction with life in men. Finally, a prospective association between weekly binge drinking and lower life satisfaction was observed in men.

Health-related quality of life in women with endometriosis: psychometric validation of the Endometriosis Health Profile 30 questionnaire using confirmatory factor analysis

STUDY QUESTION

Which of the competing models of the Endometriosis Health Profile 30 Questionnaire (EHP-30) factor structure is best supported by confirmatory factor analysis (CFA)?

SUMMARY ANSWER

Findings support a five-factor first-order model of the EHP-30, thereby lending support to the model originally suggested by the questionnaire developers.

WHAT IS KNOWN ALREADY

Endometriosis has a negative impact on quality of life, and measures specifically developed to address this impact, such as the EHP-30, are vital in research and disease management. Previous studies have found different models of the EHP-30 factor structure, and generated uncertainty regarding how to use the questionnaire. CFA can be applied to compare competing factor models and determine the underlying structure of a questionnaire.

STUDY DESIGN SIZE DURATION

This cross-sectional multicenter study included 304 women with endometriosis recruited from three different public health service endometriosis clinics (referral centers for treatment of severe endometriosis) and the Danish Endometriosis Patients Association from 2014 to 2015.

PARTICIPANTS/MATERIALS SETTING METHODS

Diagnosis of endometriosis was confirmed in medical records for 84.2% and by histology for 66.8% of participants. Questionnaires (the licensed Danish version of the EHP-30) were sent by post two times with a 6- to 12-week interval. CFA was used to examine construct validity and Bland-Altman plots to examine test-retest reliability and the convergent validity with the Short Form 36 version 2.

MAIN RESULTS AND THE ROLE OF CHANCE

Response rate was high (87.6%). CFA supported the original first-order five-factor structure of the EHP-30, and thereby, the use of five separate scale-scores in clinical and research practice. Visual inspection of Bland-Altman plots suggested excellent test-retest reliability of the EHP-30 and supported the use of a disease specific quality of life instrument for women with endometriosis.

LIMITATIONS REASONS FOR CAUTION

Diagnosis could not be confirmed through histology data in 33.2% of participants. However, subgroup analyses based on women with confirmed histology only, yielded similar results. Data related to menstrual cycle stage and the use of hormonal and pain medication during questionnaire completion were not collected. A larger study, including data from different countries on different continents, would be better designed to exclude potential population bias.

WIDER IMPLICATIONS OF THE FINDINGS

EHP-30, with its original five-factor structure, appears to be a valid, stable, and specific quality of life measure for women with endometriosis. It seems easy to understand, quick to administer, and importantly, scoring might be unaffected by cyclical/menstrual pain symptoms related to endometriosis. The finding of a five-factor model from different studies across several countries supports the crosscultural validity of the EHP-30.

STUDY FUNDING/COMPETING INTERESTS

This work was supported by the Danish Endometriosis Association, which is a nongovernmental organization run by women with endometriosis and by a scholarship from the Health Research Fund of Central Denmark Region. The authors have no conflicts of interest.

RUBIC (ReproUnion Biobank and Infertility Cohort): A binational clinical foundation to study risk factors, life course, and treatment of infertility and infertility-related morbidity

BACKGROUND

Infertility affects 15%-25% of all couples during their reproductive life span. It is a significant societal and public health problem with potential psychological, social, and economic consequences. Furthermore, infertility has been linked to adverse long-term health outcomes. Despite the advanced diagnostic and therapeutic techniques available, approximately 30% of infertile couples do not obtain a live birth after fertility treatment. For these couples, there are no further options to increase their chances of a successful pregnancy and live birth.

OBJECTIVES

Three overall questions will be studied: (1) What are the risk factors and natural life courses of infertility, early embryonic loss, and adverse pregnancy outcomes? (2) Can we develop new diagnostic and prognostic biomarkers for fecundity and treatment success? And (3) what are the health characteristics of women and men in infertile couples at the time of fertility treatment and during long-term follow-up?

MATERIAL AND METHODS

ReproUnion Biobank and Infertility Cohort (RUBIC) is established as an add-on to the routine fertility management at Copenhagen University Hospital Departments in the Capital Region of Denmark and Reproductive Medicine Centre at Skåne University Hospital in Sweden. The aim is to include a total of 5000 couples equally distributed between Denmark and Sweden. The first patients were enrolled in June 2020. All eligible infertile couples are prospectively asked to participate in the project. Participants complete an extensive questionnaire and undergo a physical examination and collection of biospecimens (blood, urine, hair, saliva, rectal swabs, feces, semen, endometrial biopsies, and vaginal swabs). After the cohort is established, the couples will be linked to the Danish and Swedish national registers to obtain information on parental, perinatal, childhood, and adult life histories, including disease and medication history. This will enable us to understand the causes of infertility and identify novel therapeutic options for this important societal problem.

Patients Decision-Making Characteristics Affects Gynecomastia Treatment Satisfaction: A Multicenter Study Using the BODY-Q Chest Module

BACKGROUND

Patient satisfaction is the most critical outcome in gynecomastia treatment. However, patient satisfaction may be affected by the patient's decision-making trait, such as exhaustively searching for the best outcome or being content with an outcome that satisfies a preconceived requirement.

OBJECTIVE

To assess whether patient's decision-making characteristic affect their satisfaction with gynecomastia treatment.

METHODS

This was a cross-sectional study including patients treated for gynecomastia between January 2009 and December 2019 at two tertiary hospitals in Denmark. Alive patients were sent the BODY-Q: Chest module, the SF-36 questionnaire, and the Maximizer/Satisficer decision-making survey. Patients were classified as Maximizers if they scored more than 40 points on the Maximizer/Satisficer survey. Percentage score differences (PDs) in quality of life scales were calculated between Maximizers and Satisficers.

RESULTS

In total, 192 gynecomastia patients were included in this study and classified as Maximizers (n = 152) or Satisficers (n = 40). Maximizers were younger and more had gynecomastia following abuse of anabolic steroids than Satisficers (p < 0.05). With respect to bodily satisfaction, Maximizers showed significantly worse satisfaction with nipples (PDs: - 12.98%), psychological function (PDs: - 13.68%) and social function (PDs: - 8.77%, p < 0.05). In addition, Maximizers had significantly worse emotional role functioning (- 11.03%), vitality (PDs: - 11.72%) and mental health (PDs: - 10.00%, p < 0.05).

CONCLUSION

Patients exhibiting maximizing-type decision-making characteristics have worse satisfaction with gynecomastia treatment and poorer psychosocial health. This information may facilitate patient counseling and alignment of treatment expectations.

Patient-reported outcome measures for clinical decision-making in outpatient follow-up: validity and reliability of a renal disease questionnaire

BACKGROUND

Patient-reported outcome measures are increasingly used by clinicians to support communication in telephone- or face-to-face consultations with patients. A renal disease questionnaire has been developed, but not sufficiently evaluated through clinimetrics in clinical setting. Hence, we aimed to evaluate the content validity, construct validity and the test-retest reliability of a renal disease questionnaire to be used for clinical decision-making.

METHODS

A content, construct validity and test-retest reliability study was conducted in 3 nephrology outpatient clinics in Central Denmark Region, Denmark. Content validity (face validity, comprehensibility and relevance) was assessed among 8 patients and 6 clinicians. Reliability was assessed by asking outpatients with chronic kidney disease to complete the questionnaire twice. Reliability was assessed by kappa statistics and agreement by percentage. Construct validity was determined using 4 a priori defined hypotheses and comparing 2 known groups.

RESULTS

Five new domains emerged, 6 items were rephrased and 3 items were removed following the content validity test. A total of 160 patients completed the questionnaire with median 8 days (IQR 2 days) between assessments. The test-retest reliability parameters of the single items in the questionnaire were substantial to almost perfect as all the observed weighted kappa values ranged from 0.61 to 0.91, 95% CI (0.34 to 0.95). In total, 61% of the single items showed almost perfect agreement. In total, 3 of the 4 hypotheses were accepted and 44% of the items showed satisfying known-group discriminative validity.

CONCLUSION

A renal disease questionnaire used for clinical decision-making in outpatient follow-up showed acceptable content validity and substantial to almost perfect reliability. Sufficient construct validity was not established. Incorporating the questionnaire into routine clinical practice may improve the evaluation of disease burden in patients with chronic kidney disease. We ask patients with chronic kidney disease (CKD) in Central Region Denmark to complete a questionnaire before each outpatient visit. The answers they provide are used to support communication with their health care provider. A questionnaire requires testing to ensure it can accurately capture important information about patient's symptoms and quality of life. When questionnaires are used to support communication between patients and health care professionals, they need to have good measurement properties. This means they need to be: (1) trustworthy, (2) relevant to a patient's health condition, (3) consistent and produce stable results every time. We explored the measurement properties of a questionnaire designed to be used in the face-to face outpatient visits for patients with CKD. We found that the questionnaire captured consistent and stable results. Using this questionnaire may help health care professionals to assess the patients´ burden of symptoms with a more patient-centered approach. Potentially, the use of the questionnaire will increase the patients´ ability to cope with their symptoms and strengthen patients´ involvement in the clinical decisions concerning their treatment.

Impact of the COVID-19 pandemic on biopsychosocial health and quality of life among Danish children and adults with neuromuscular diseases (NMD)-Patient reported outcomes from a national survey

The purpose was to investigate the impact of the COVID-19 pandemic on biopsychosocial health, daily activities, and quality of life among children and adults with neuromuscular diseases, and to assess the prevalence of COVID-19 infection and the impact of this in patients with neuromuscular diseases. The study was a national questionnaire survey. Responses were obtained from 811 adults (29%) and 67 parents of children (27%) with neuromuscular diseases. Many patients reported decreased health or physical functioning, and changes in access to physiotherapy or healthcare due to the pandemic. Participants generally perceived themselves or their child to be at high risk of severe illness from COVID-19, but only 15 patients had suffered from COVID-19 and experienced mild flu-like symptoms. 25.3% of adults and 46.6% of parents experienced anxiety. 20.4% of adults and 27.6% of parents experienced symptoms of depression. In general, the pandemic contributed to anxiety, a depressed mood as well as to fewer leisure activities, less social contact, isolation from work/school and a reduced quality of life, in particular for patients who perceived themselves to be at high risk of severe illness. The results demonstrate that the pandemic has had a negative impact on biopsychosocial health and quality of life of patients with neuromuscular diseases.

Involving frail older patients in identifying outcome measures for transitional care-a feasibility study

BACKGROUND

During care transitions, the older (75+) patient's agenda can easily be missed. To counteract this, involving patients in shared clinical decision making has proven to be of great value. Likewise, involving patients and other stakeholders as researchers is gaining ground. Patient and public involvement (PPI) in research entails many benefits, for example, by bringing further insight from those with lived experiences of being ill. There are various challenges associated with involving some older patients, for example frailty, cognitive impairment and other chronic illnesses. To the best of our knowledge, there are only a few examples of initiatives involving older patients beyond research participation. The feasibility of involving frail older patients during an ongoing care transition from hospital to primary health care remains unknown. To investigate the feasibility of including older frail patients, their relatives and health care professionals (HCPs) as co-researchers, we established a study with increasingly demanding levels of patient involvement to identify relevant outcome measures for future transitional care research.

METHODS

The study was a pragmatic, qualitative feasibility study. The involved individuals were frail older patients, their relatives and HCPs. Patients and their relatives were interviewed, while the interviewer made reflective notes. A thematic analysis was made. Relatives and HCPs discussed the themes to identify relevant outcome measures and potentially co-create new patient-reported outcome measures (PROMs) for use in future transitional care studies. The feasibility was evaluated according to six involvement steps. The level of involvement was evaluated using the five-levelled Health Canada Public Involvement Continuum (HCPIC).

RESULTS

In total, eight patients, five relatives and three HCPs were involved in the study. Patients were involved in discussing care transitions (HCPIC level 3), while some relatives were engaged (HCPIC level 4) in forming PROMs. The partnership level of involvement (HCPIC level 5) was not reached. The thematic analysis and the subsequent theme discussion successfully formed PROMs. The key PROMs were related to care, transparency and the relatives' roles in the transitional care process.

CONCLUSIONS

When applying a pragmatic involvement approach, frail older patients can be successfully involved in identifying relevant transitional care outcome measures; however, involving these patients as fellow researchers seems infeasible. To maintain involvement, supportive relatives are essential. Useful experiences for future research involvement of this vulnerable group were reported, arguing that patient participation has the potential to become inherent in future geriatric research.

The impact of lymphedema on health-related quality of life up to 10 years after breast cancer treatment

The impact of breast cancer-related lymphedema (BCRL) on long-term quality of life is unknown. The aim of this study was to investigate the impact of BCRL on health-related quality of life (HRQoL) up to 10 years after breast cancer treatment. This regional population-based study enrolled patients treated for breast cancer with axillary lymph node dissection between January 1st 2007 and December 31th 2017. Follow up and assessments of the included patients were conducted between January 2019 and May 2020. The study outcome was HRQoL, evaluated with the Lymphedema Functioning, Disability and Health Questionnaire, the Disabilities of the Arm, Shoulder and Hand Questionnaire and the Short Form (36) Health Survey Questionnaire. Multivariate linear logistic regression models adjusted for confounders provided mean score differences (MDs) with 95% confidence intervals in each HRQoL scale and item. This study enrolled 244 patients with BCRL and 823 patients without BCRL. Patients with BCRL had significantly poorer HRQoL than patients without BCRL in 16 out of 18 HRQoL subscales, for example, in physical function (MDs 27, 95%CI: 24; 30), mental health (MDs 24, 95%CI: 21; 27) and social role functioning (MDs 20, 95%CI: 17; 23). Age, BMI, BCRL severity, hand and dominant arm affection had only minor impact on HRQoL (MDs < 5), suggesting a high degree of inter-individual variation in coping with lymphedema. This study showed that BCRL is associated with long-term impairments in HRQoL, especially affecting the physical and psychosocial domains. Surprisingly, BCRL diagnosis rather than clinical severity drove the largest impairments in HRQoL.

Early Occupational Intervention for People with Low Back Pain in Physically Demanding Jobs: 1-year Follow-up Results of the Randomized Controlled GOBACK Trial

STUDY DESIGN

Randomized controlled trial with 1-year follow up.

OBJECTIVE

The aim of this study was to assess whether people with low back pain (LBP) and self-reported physically demanding jobs, benefit from an occupational medicine intervention, in addition to a single hospital consultation and a magnetic resonance imaging, at 1 year of follow-up. Secondly, to examine whether the positive health effects, found in both groups at 6 months, persist at 1-year follow-up.

SUMMARY OF BACKGROUND DATA

The prevalence of LBP is high in the working population, resulting in a substantial social and economic burden. Although there are many guidelines available on the management of LBP, including multidisciplinary biopsychosocial rehabilitation, they provide limited guidance on the occupational medicine aspects.

METHODS

As reported previously, 305 participants with LBP and self-reported physically demanding jobs were enrolled in the randomized controlled study and randomly allocated to clinical care with additional occupational medicine intervention or clinical care alone. Data were collected at baseline, 6 months, and 1 year. Outcomes included in the present 1-year follow-up study are changes in neuropathic pain (painDETECT questionnaire), severity of pain (0-10 numerical rating scale), disability (Roland Morris Disability Questionnaire), fear-avoidance beliefs (FABQ), physical, and mental quality of life (short-form 36).

RESULTS

The study showed no effect of an occupational intervention on neuropathic pain, fear-avoidance beliefs, physical and mental quality of life nor disability measured after 1 year. The positive effects found at 6 months in both groups, remained at 1-year follow-up.

CONCLUSION

The results suggest that a thorough clinical consultation, with focus on explaining the cause of pain and instructions to stay active, can promote long-lasting physical and mental health in individuals with LBP. Therefore, additional occupational interventions could focus on altering occupational obstacles on a structural level.Level of Evidence: 2.

Validation of the colostomy impact score in patients ostomized for a benign condition

AIM

The colostomy impact (CI) score is a patient-reported outcome measure assessing reduction in health-related quality of life (HRQL) due to a stoma. The score was originally developed and validated in a cohort of rectal cancer survivors with a permanent colostomy. For the CI score to be applied to patients with a colostomy after surgery for a benign condition it must be validated in this patient group. The aim of this study was to assess construct validity and known groups validity of the CI score in patients with a colostomy after surgery for a benign condition.

METHOD

In a cross-sectional survey among ostomates in the Capital Region of Denmark, patients completed the CI score and the SF-36 v2 questionnaires. Construct validity was assessed by Pearson's correlation coefficients and known groups validity was assessed by t-test when dividing patients into groups of minor or major CI.

RESULTS

The CI score showed a moderate negative correlation with the Physical Component Summary (PCS) of -0.41 and a weak negative correlation with the Mental Component Summary (MCS) of -0.39. The strength of the correlation depended on the underlying condition leading to stoma formation. Differences were significant between the minor and major CI groups in mean PSC and MCS with t-values of 5.32 and 3.86, respectively.

CONCLUSION

The CI score is a valid instrument for assessing stoma-related impact on HRQL regardless of the underlying condition leading to stoma formation, and the CI score discriminates meaningfully between groups with known differences in stoma-related reduced HRQL.

Feasibility of group-based acceptance and commitment therapy for adolescents (AHEAD) with multiple functional somatic syndromes: a pilot study

BACKGROUND

Recurrent and impairing functional somatic syndromes (FSS) are common in adolescents. Despite a high need for care, empirically supported treatments are lacking for youth. The aim of this uncontrolled pilot study was to assess feasibility and treatment potential of a new intervention with group-based Acceptance and Commitment Therapy (ACT) in a generic treatment approach for adolescents with multiple FSS.

METHODS

Twenty-one patients received 'ACT for Health in Adolescents' (AHEAD) (30 h), specifically developed for adolescents (aged 15-19 years) with moderate to severe FSS. Close relatives attended an information meeting to facilitate support of the patients throughout treatment. Treatment satisfaction was evaluated by means of self-report and relatives' impressions. Self-reported physical health at 3 months follow-up (FU) after end of treatment was the primary outcome whereas secondary outcomes included symptom burden, limitation due to symptoms, illness worry, emotional distress and physical and emotional symptoms. Treatment targets were assessed by measures on illness behaviour, illness perception and psychological inflexibility.

RESULTS

Nineteen patients (90.5%) completed the treatment with a high overall attendance rate of 93%. All would recommend the treatment to a friend with similar problems. Close relatives rated it valuable to participate in an information meeting. Patients' physical health improved significantly from assessment to FU with a clinically relevant mean change of 8.9 points (95% CI [5.4; 12.4]; SRM 0.91 [0.26;1.57]). Improvement was also seen on all secondary outcome measures, from assessment to FU. Maladaptive illness behaviours and perceptions as well as psychological inflexibility showed a significant decline from assessment to FU.

CONCLUSION

AHEAD was feasible and potentially efficacious and warrants testing in a larger clinical trial.

Autologous fat grafting seems to alleviate postherpetic neuralgia - a feasibility study investigating patient-reported levels of pain

BACKGROUND

Postherpetic neuralgia (PHN) is a relatively common side effect after an outbreak of herpes zoster (HZ), characterized by chronic neuropathic dermal pain. No effective treatment exists today. Fat grafting has shown promise in alleviating neuropathic pain, yet the exact mechanism of action, at a biological level, is not yet known. We report on the first human study using autologous fat grafting for treating PHN. Our hypothesis was that fat grafting can alleviate pain and improve the quality of life (QoL) in patients suffering from PHN. If successful, this could be a safe, cost-effective alternative to analgesics. This safety and feasibility study aimed to investigate the possible pain-relieving effect of autologous fat grafting on PHN.

METHODS

Ten adult patients suffering from PHN underwent autologous fat grafting to a dermal area of neuralgia, with a 12-week follow up. The primary endpoint was patient-reported pain. Secondary endpoints were patient-reported changes in QoL, and the degree and quality of the neuropathic pain.

RESULTS

The pain was measured by using a visual analog scale (range: 0-10). We observed improvements in both the average and maximum level of pain with a reduction of (-4.0 ± 3.1) and (-5.1 ± 3.9), respectively, (Δ mean ± SD), P<0.05. All parameters investigating neuropathic pain were significantly reduced. No improvement was seen in the QoL. The average amount of fat grafted was 208 ml. We observed no serious adverse effects.

CONCLUSION

This study suggests that autologous fat grafting can relieve chronic pain resulting from HZ. The next step toward routine clinical translation is to perform a randomized, blinded, placebo-controlled trial with a more extended follow-up period.

Resistance Training Increases Muscle Strength and Muscle Size in Patients With Liver Cirrhosis

BACKGROUND & AIMS

Cirrhosis is often complicated by reduced muscle mass and strength, which limits the ability to perform daily activities and affects quality of life. Resistance training can increase muscle strength and mass in elderly and chronically ill patients. We performed a randomized controlled trial to investigate whether resistance training increases muscle strength and size in patients with compensated cirrhosis.

METHODS

We performed a prospective study of 39 patients with cirrhosis (Child-Pugh class A or B) seen at an outpatient clinic in Denmark from January 2015 through March 2017. Participants protein intake and activity levels were registered daily. Participants were randomly assigned (1:1) to a group that performed 36 1-hour sessions of physical exercise (supervised progressive resistance training for 1 hour, 3 times weekly for 12 weeks) or a control group (no change in daily activity level). Maximal muscle strength was measured as the peak torque in isokinetic knee extension and muscle size was measured as the cross-sectional area of the quadriceps muscle, assessed by magnetic resonance imaging of the thigh.

RESULTS

The exercise group increased their muscle strength by 13% (from a mean 119 Nm to 134 Nm)-an 11 Nm greater gain in mean strength than that of the control group (P = .05). The exercise group increased their quadriceps cross-sectional area by 10% (from a mean 58.5 cm² to 64.6 cm²)-a 4.4 cm² greater gain than that of the control group (P < .01). The exercise group had significant increases in whole-body lean mass and body cell mass, and significant increases in 6-minute walking distance and the mental component summary of the short form-36 questionnaire. Adverse events were minor and equal between groups.

CONCLUSIONS

In a randomized trial of patients with compensated cirrhosis, we found that 12 weeks of supervised progressive resistance training increased muscle strength and size and had beneficial effects on general performance measures, compared with patients who did not change their daily activity routine (control subjects).

Work-related stressors, depression and quality of life in Danish managers

Background

By use of valid questionnaires to investigate work-related stress and distress in Danish managers.

Methods

The survey focused on members of the Danish Association of Managers and Executives who no longer were active (formermanagers' group). Acting managers (active managers' group) served as controls. Questionnaires measuring stressors at work and general life events were used. For the measurement of distress, scales for depression and quality of life were used.

Results

The Mokken analysis proved the validity of the questionnaires, i.e. their summed-up total scores were sufficient statistics. No differences were found between former (n = 1256) and active managers (n = 942) as to life events. Approximately 20% of former managers were at risk of depression and 12% had developed major depression. Among the specific work-related stressors were role overload, lack of team spirit and lack of social support. The percentage of active managers at risk of or suffering from major depression did not differ significantly from the Danish general population. Approximately 37% of the former managers had a decreased well-being. Alcohol use was found to be significantly associated with depression.

Conclusions

The study identified specific work-related stressors in managers, 12% of whom developed a major depression.

Socio-demographic, clinical and psychological predictors of healthcare utilization among patients with musculoskeletal disorders: a prospective cohort study

BACKGROUND

Musculoskeletal disorders are common in the general population and a leading cause for care seeking. Despite the large number of patients with musculoskeletal disorders seeking care, little is known of the clinical course, pathways and predictors of healthcare utilization among these patients. The purposes of the study were to 1) describe the clinical course and related healthcare utilization in primary care physiotherapy and secondary healthcare among patients with neck, shoulder and low-back pain treated in physiotherapy practice, and 2) identify independent clinical, socio-demographic, psychological and general health predictors of healthcare utilization.

METHODS

The study was a prospective cohort study of patients seeking physiotherapy treatment for neck, shoulder, or low-back pain in physiotherapy practices across Denmark. A total of 759 physiotherapy patients completed questionnaires containing information on clinical course and potential predictors of healthcare utilization. Healthcare utilization was obtained from the Danish National Health Service Register and National Patient Register. Associations between potential predictors and low/high primary care physiotherapy utilization and hospital contacts in relation to specific neck, shoulder or low-back disorders were analysed using binomial regression analyses and adjusted for age, sex, duration of pain and comorbidity.

RESULTS

During 6 months follow-up, patients experienced clinically relevant improvements in pain, fear avoidance and psychological wellbeing. Patients with higher baseline pain and disability and who were on sickness leave were more likely to have high primary care physiotherapy utilization. Hospital contacts were predicted by higher levels of pain, disability and low psychological wellbeing.

CONCLUSIONS

Clinical factors and sickness leave seems to be the main predictors of primary care physiotherapy utilization, whereas for secondary care contacts, psychological factors may also be of importance. The study contributes to the on-going research into clinical pathways and may identify future target areas to reduce healthcare utilization in patients with musculoskeletal disorders.

Sexual dysfunction and mental health in patients with multiple sclerosis and epilepsy

BACKGROUND

Epilepsy and multiple sclerosis (MS) are two neurological diseases known to greatly influence a patient's life. The primary aim of this study was to describe the prevalence of sexual dysfunction in patients with epilepsy and MS and investigate whether there is an association between disease, sexual function, and physical and mental health. A secondary aim was to investigate whether there is a difference in sexual function between patients with MS and epilepsy.

METHODS

A total of 414 patients were included in this descriptive cross-sectional study. Three patient report questionnaires were used for measurements: the Changes in Sexual Function Questionnaire (CSFQ) cut-off score; the Short Form 36 Health Survey (SF-36) divided into the Physical Component Summary (PCS) and Mental Component Summary (MCS), and the Life Satisfaction-11 (LiSat-11).

RESULTS

Patients with MS constituted 62% (n = 258) of the participants and patients with epilepsy 38% (n = 156). The prevalence of sexual dysfunction was 68% in women and 77% in men. No differences were found between patients with MS and epilepsy (p = 0.184), except for the CSFQ desire domain, as patients with epilepsy more often had a desire problem (p = 0.029). On the SF-36, patients with MS scored significantly worse on the PCS (p = 0.000). Patients with epilepsy scored significantly worse on the MCS (p = 0.002). No significant differences were found on the LiSat-11. Regression analysis with CSFQ as the dependent variable showed an association with the PCS in men and an association with both PCS and MCS in women.

CONCLUSIONS

In this study, the cohort of patients with MS and epilepsy had negatively affected sexual function. The only significant difference between patients with MS and epilepsy in sexual function measured by the CSFQ-14, was found in the frequency of desire, in which a larger number of patients with epilepsy reported sexual dysfunction. In the studied cohort, sexual function in women is associated with both physical and mental health, and in men with physical health. These results should be considered when caring for patients with epilepsy and MS.

Sociodemographic, personal, and disease-related determinants of referral to patient-reported outcome-based follow-up of remote outpatients: a prospective cohort study

Purpose

We examined the association between sociodemographic, personal, and disease-related determinants and referral to a new model of health care that uses patient-reported outcomes (PRO) measures for remote outpatient follow-up (PRO-based follow-up).

Methods

We conducted a prospective cohort study among outpatients with epilepsy at the Department of Neurology at Aarhus University Hospital, Denmark. Included were all persons aged ≥ 15 years visiting the department for the first time during the period from May 2016 to May 2018. Patients received a questionnaire containing questions about health literacy, self-efficacy, patient activation, well-being, and general health. We also collected data regarding sociodemographic status, labour market affiliation, and co-morbidity from nationwide registers. Associations were analysed as time-to-event using the pseudo-value approach. Missing data were handled using multiple imputations.

Results

A total of 802 eligible patients were included in the register-based analyses and 411 patients (51%) responded to the questionnaire. The results based on data from registers indicated that patients were less likely to be referred to PRO-based follow-up if they lived alone, had low education or household income, received temporary or permanent social benefits, or if they had a psychiatric diagnosis. The results based on data from the questionnaire indicated that patients were less likely to be referred to PRO-based follow-up if they reported low levels of health literacy, self-efficacy, patient activation, well-being, or general health.

Conclusion

Both self-reported and register-based analyses indicated that socioeconomically advantaged patients were referred more often to PRO-based follow-up than socioeconomically disadvantaged patients.

Impact of a Parastomal Bulge on Quality of Life - A Cross-sectional Study of Patients From the Danish Stoma Database

OBJECTIVE

To investigate stoma specific and generic HRQoL in patients with and without a parastomal bulge.

BACKGROUND

Most patients have to live with their stoma complicated by a parastomal bulge. How this affects quality of life remains unclear.

METHODS

Patients in the Danish Stoma Database completed the Short-form 36 health survey and the stoma-QOL questionnaire. Linear regression analysis, adjusted for potential confounding factors, provided mean and mean score differences and 95% confidence intervals for each HRQoL scale and item. Cohens d provided estimates of effect size.

RESULTS

A total of 1265 patients (65%) completed the questionnaire 4.4 (interquartile range 3.1-6.0) years after stoma surgery. Of these, 693 (55%) patients with a parastomal bulge had significantly impaired (P < 0.01) HRQoL across all stoma specific and generic health domains compared to patients without a parastomal bulge. In patients with a benign diagnosis or an ileostomy, a parastomal bulge impacted significantly on Social Functioning and Mental Health resulting in a worse Mental Component Summary. A large bulge >10 cm impaired HRQoL (P < 0.01) across all stoma specific and generic domains. The impact on HRQoL was independent of time with the bulge.

CONCLUSIONS

A novel finding in this large, unselected sample from high-quality regional registries was that parastomal bulging was associated with substantial and sustained impairment of HRQoL.

Birth weight and quality of life in midlife: a 50-year follow-up study of 2079 individuals in Denmark

PURPOSE

Low birth weight has been associated with a higher risk of reduced quality of life (QoL) in children, adolescents, and young adults, but the influence seems to diminish over time. However, previous studies have mainly focused on health-related QoL and compared individuals with low birth weight with individuals without low birth weight. The purpose of the present cohort study was to investigate the influence of the entire range of birth weights on three distinct measures of QoL in midlife.

METHODS

The study population consisted of all live-born singletons from the Copenhagen Perinatal Cohort (CPC, 1959-1961) who participated in a 50-year follow-up examination in 2009-2011 (N = 2079). Birth weight was measured by three pediatricians at birth. QoL was measured at the follow-up by the participants' scores on three QoL self-report measures: The Satisfaction With Life Scale, the Vitality Scale of the Medical Outcomes Study 36-Item Short-Form Health Survey, and a single-item QoL measure based on the question: "How is your quality of life at the moment?". General linear regression and binary logistic regression were used to estimate the association between birth weight and QoL in midlife.

RESULTS

Small, curvilinear associations of birth weight with life satisfaction, vitality, and the single-item QoL measure were found, suggesting that both low and high birth weights increase the risk of low satisfaction with life, low vitality and low QoL.

CONCLUSION

The study findings suggest that low and high-range birth weight exert a lasting influence on distinct, but complementary aspects of QoL in midlife.

Treatment of chronic post-herpetic neuralgia with autologous fat grafts: a first-in-the-world case report

A 60-year-old woman suffering from severe chronic post-herpetic neuralgia (PHN) was treated with simple autologous fat grafting to the affected area of skin. Post-operatively, she reported a great improvement in her symptoms. The effect was stable throughout the 3-month follow-up period. This case report presents a first-in-the-world case of using fat grafting to treat chronic post-herpetic neuralgia and discusses the future potential of this as a primary treatment of this syndrome. This report presents partial data of a pilot study registered at clinicaltrials.org (ClinicalTrials.gov Identifier: NCT03584061).

Patient-initiated versus fixed-interval patient-reported outcome-based follow-up in outpatients with epilepsy: a pragmatic randomized controlled trial

BACKGROUND

The use of patient-reported outcome (PRO) could potentially contribute to the reorganization of the health care system. AmbuFlex is a PRO system used in remote patient monitoring, in which questionnaires are sent to patients at fixed intervals. The PRO data are used by clinicians to decide whether patients need clinical attention. Better self-management and cost-saving follow-up activities may be achieved by letting patients initiate need of contact. We evaluated the effects of patient-initiated PRO-based outpatient follow-up on health care resource utilization, quality of care, and the patient perspective.

METHODS

We conducted a parallel two-arm pragmatic randomized controlled trial at the Department of Neurology, Aarhus University Hospital, Denmark. Outpatients with epilepsy (≥ 15 years old), attending fixed-interval PRO-based follow-up with web-based questionnaires, were randomly assigned in a ratio of 0.55:0.45 to either 1) patient-initiated PRO-based follow-up (open access telePRO) or 2) fixed-interval PRO-based follow-up (standard telePRO). The primary outcome was the number of outpatient hospital contacts related to epilepsy retrieved from a regional registry. Hospitals admissions and emergency room visits were also assessed. Secondary self-reported outcomes including general health, well-being, health literacy, self-efficacy, number of seizures, side effects, confidence, safety, and satisfaction were retrieved from questionnaires. Data were analyzed by the intention-to-treat and per-protocol approaches.

RESULTS

Between January 2016 and July 2016, 593 patients were randomized to either open access telePRO (n = 346) or standard telePRO (n = 247). At 18 months, no statistically significant differences were found between the arms regarding number of telephone consultations or outpatient visits. Patients in the open access arm had a slightly lower, statistically significant number of emergency room visits than patients in the standard arm. Self-reported mental well-being in the open access arm was slightly, statistically significantly lower than in the standard arm. Other secondary outcomes did not differ statistically significantly between arms.

CONCLUSION

This study did not find, as hypothesized, less use of health care resources or improved patient self-management or satisfaction in the patient-initiated PRO-based initiative compared to fixed-interval PRO-based follow-up. Patient-initiated PRO-based follow-up may be used as an alternative to fixed-interval PRO-based follow-up in patients who prefer this approach, but there is insufficient evidence for recommending a system-wide shift to patient-initiated PRO-based follow-up.

Accuracy of self-referral in health anxiety: comparison of patients self-referring to internet-delivered treatment versus patients clinician-referred to face-to-face treatment

BACKGROUND

Severe health anxiety is a chronic and costly disorder if untreated. Patient self-referral may lower barriers to treatment and decrease diagnostic delay.

AIMS

This study evaluated the accuracy of self-referral for severe health anxiety and compared characteristics of patients self-referred to internet-delivered treatment with patients referred by a clinician to face-to-face treatment.

METHOD

Two trials in the same clinic employed different referral methods for health anxiety, namely self-referral and clinician-referral (trial registration: clinicaltrials.gov: NCT01158430 and NCT02735434). The trials were conducted at different time points but with largely comparable eligibility criteria. The accuracy of the recruitment methods was compared by looking at the number of eligible patients in the two trials. Patients completed a baseline questionnaire and subsequently underwent a diagnostic interview by experienced clinicians. Mean differences in self-report and clinical data explored between-group demographic and clinical characteristics.

RESULTS

In total, 101/151 (67%) self-referred patients were eligible compared with 126/254 (50%) clinician-referred patients (P = 0.001). Self-referred patients were 3.4 years older (P = 0.008) and had a somewhat higher educational level (P = 0.030). Patients who self-referred reported significantly higher levels of health anxiety, emotional distress and somatic symptoms compared with clinician-referred patients. Yet, they had less clinician-assessed comorbid anxiety disorders (P<0.001) and better physical health-related quality of life (P<0.001) suggesting a more distinct symptom profile.

CONCLUSIONS

Self-referral was found to be an accurate method to recruit highly relevant patients with treatment-demanding health anxiety. Thus, both self-referral and clinician-referral seem feasible and valid referral methods, but they may recruit patients with slightly different characteristics.

Remote follow-up using patient-reported outcome measures in patients with chronic kidney disease: the PROKID study - study protocol for a non-inferiority pragmatic randomised controlled trial

Background

Outpatient care is steadily changing from hospital consultations to other platforms, such as phone consultation and online virtual clinics. It is prudent to maintain quality of care with such initiatives. Currently, patients with chronic kidney disease (CKD) have frequent scheduled visits, but it may be possible to optimise the frequency of hospital consultations using information from patient-reported outcome (PRO) questionnaires filled in at home (PRO-based follow-up). This approach may provide a more individually tailored follow-up based on actual needs for clinical attention. We aimed to evaluate the effectiveness of the quality of care, use of resources and patient outcomes associated with PRO-based follow-up in patients with CKD.

Methods

This study is a pragmatic, non-inferiority, randomised controlled trial in outpatients with CKD (Grove BE et al., Qual Life Res 27: S143, 2018). Newly referred patients with an estimated glomerular filtration rate (eGFR) of ≤40 ml/min 1.73m² will be randomised to either:

PRO-based remote follow-up

PRO-based telephone consultation

Usual outpatient follow-up (control group)

In the two intervention groups, a diagnosis-specific PRO questionnaire completed by the patient at home will substitute for usual outpatient follow-up visits. The PRO questionnaire will in part be used as a screening tool to identify patients in need of outpatient contact and to identify focus areas. Responses from the questionnaire will be processed according to a disease-specific algorithm and assigned green, yellow or red status according to patients’ needs.

The primary outcome will be loss of renal function evaluated by eGFR. Secondary outcomes are 1. Clinical outcomes, including initiation of acute dialyses, hospitalisation and mortality, 2. Utilisation of healthcare resources and 3. PRO measures, primarily quality of life (Euroqol EQ-5D) and illness perception (Brief Illness Perception Questionnaire (BIPQ).

Discussion

Benefits and possible drawbacks of the PRO-based follow-up will be evaluated. If PRO-based follow-up proves non-inferior to usual outpatient follow-up, a reorganisation of routine clinical practice in nephrology outpatient clinics may occur. Further, results may impact other patient groups with chronic conditions attending regular follow-up.

"Understand your illness and your needs": Assessment-informed patient education for people with multiple functional somatic syndromes

OBJECTIVES

Patients suffering from multiple functional somatic syndromes (FSS) such as fibromyalgia, chronic fatigue syndrome, or irritable bowel syndrome, often lack both a clear diagnosis and tangible illness explanations, which is a barrier for treatment engagement. We tested a short-term intervention taking the unifying concept of Bodily Distress Syndrome (BDS) as a point of departure. The intervention consisted of a clinical assessment, group-based patient education, and one follow-up consultation.

METHODS

174 patients were included and received questionnaires at baseline, after clinical assessment, after patient education, and median 19 weeks after baseline. Data were analyzed using random effects models and simple t-tests. Qualitative data were thematically analyzed.

RESULTS

We found small reductions in symptom levels, considerable reductions in illness worry, and improvement of illness perceptions and illness-related behaviors. Overall, patients evaluated the intervention positively and expressed high expectations for further treatment. Qualitative results mainly supported these findings.

CONCLUSION

Targeting illness perceptions through patient education is crucial to obtain patient engagement in self-help management or further treatment. This may lead to improved outcomes.

PRACTICAL IMPLICATIONS

Physicians in primary and secondary care should strive to give patients with multiple FSS a clear understanding that their various FSS diagnoses are related and provide tangible illness explanations.

Early occupational intervention for people with low back pain in physically demanding jobs: A randomized clinical trial

BACKGROUND

Occupational medicine seeks to reduce sick leave; however, evidence for an add-on effect to usual care is sparse. The objective of the GOBACK trial was to test whether people with low back pain (LBP) in physically demanding jobs and at risk of sick leave gain additional benefit from a 3-month complex intervention that involves occupational medicine consultations, a work-related evaluation and workplace intervention plan, an optional workplace visit, and a physical activity program, over a single hospital consultation and an MRI.

METHODS AND FINDINGS

We enrolled people from the capital region of Denmark to an open-label, parallel-group randomized controlled trial with a superiority design from March 2014 through December 2015. In a hospital setting 305 participants (99 women) with LBP and in physically demanding jobs were randomized to occupational intervention (n = 153) or no additional intervention (control group; n = 152) added to a single hospital consultation giving a thorough explanation of the pain (i.e., clinical examination and MRI) and instructions to stay active and continue working. Primary outcome was accumulated sick leave days due to LBP during 6 months. Secondary outcomes were changes in neuropathic pain (painDETECT questionnaire [PDQ]), pain 0-10 numerical rating scale (NRS), Fear-Avoidance Beliefs Questionnaire (FABQ), Roland-Morris Disability Questionnaire (RMDQ), Short Form Health Survey (SF-36) for physical and mental health-related quality of life (HRQoL), and self-assessed ability to continue working (range 0-10). An intention-to-treat analysis of sick leave at 6 months showed no significant difference between groups (mean difference in days suggestively in favor of no additional intervention: 3.50 [95% CI -5.08 to 12.07], P = 0.42). Both groups showed significant improvements in average pain score (NRS), disability (RMDQ), fear-avoidance beliefs about physical activities and work (FABQ), and physical HRQoL (SF-36 physical component summary); there were no significant differences between the groups in any secondary outcome. There was no statistically significant improvement in neuropathic pain (PDQ score), mental HRQoL (SF-36 mental component summary), and self-assessed ability to stay in job. Four participants could not complete the MRI or the intervention due to a claustrophobic attack or accentuated back pain. Workplace visits may be an important element in the occupational intervention, although not always needed. A per-protocol analysis that included the 40 participants in the intervention arm who received a workplace visit as part of the additional occupational intervention did not show an add-on benefit in terms of sick leave (available cases after 6 months, mean difference: -0.43 days [95% CI -12.8 to 11.94], P = 0.945). The main limitations were the small number of sick leave days taken and that the comprehensive use of MRI may limit generalization of the findings to other settings, for example, general practice.

CONCLUSIONS

When given a single hospital consultation and MRI, people in physically demanding jobs at risk of sick leave due to LBP did not benefit from a complex additional occupational intervention. Occupational interventions aimed at limiting biopsychological obstacles (e.g., fear-avoidance beliefs and behaviors), barriers in the workplace, and system barriers seem essential to reduce sick leave in patients with LBP. This study indicates that these obstacles and barriers may be addressed by thorough usual care.

Management of people with Type 2 diabetes shared between a specialized outpatient clinic and primary health care is noninferior to management in a specialized outpatient clinic: a randomized, noninferiority trial

AIM

To evaluate whether management of people with Type 2 diabetes shared between a specialized outpatient clinic and primary health care has noninferior HbA_1c outcomes compared with mono-sectorial management in a specialized outpatient clinic.

METHODS

A randomized controlled, noninferiority study. People with moderate hyperglycaemia, hypertension and/or incipient complications were eligible for the study. All participants had annual comprehensive check-ups at the outpatient clinic. Quarterly check-ups were conducted by general practitioners (GPs) for the shared care group and by endocrinologists at the outpatient clinic for the control group. The primary outcome was the mean difference in HbA_1c from baseline to 12 months of follow-up. The noninferiority margin for HbA_1c was 4.4 mmol/mol.

RESULTS

A total of 140 people were randomized [age 65.0 ± 0.9 years, HbA_1c 52 ± 0.8 mmol/mol (6.9 ± 0.1%), systolic BP 135.6 ± 1.1 mmHg; all mean ± sem]. Peripheral neuropathy was present in 68% of participants and microalbuminuria in 19%; 15% had history of a previous major cardiovascular event. Among study completers (n = 133), HbA_1c increased by 2.3 mmol/mol (0.2%) in the shared care group and by 1.0 mmol/mol (0.1%) in the control group, with a between-group difference of 1.3 mmol/mol [90% confidence interval (CI) -1.3, 3.9] (0.1%, 90% CI -0.1, 0.4). Noninferiority was confirmed in both per protocol and intention to treat analyses.

CONCLUSION

We found that our shared care programme was noninferior to specialized outpatient management in maintaining glycaemic control in this group of people with Type 2 diabetes. Shared care should be considered for the future diabetes management of Type 2 diabetes.

Detecting True Change in the Hospital Anxiety and Depression Scale, SF-36, and Hypothyroid Score when Monitoring Patients with Subclinical Hypothyroidism

Guidelines suggest that subclinical hypothyroid (SCH) patients with thyrotropin (TSH) between 4 and 10 mU/L and symptoms associated with hypothyroidism should receive L-T4 substitution treatment, be evaluated, and continue treatment if symptoms subside. The latter requires detecting a true change in symptoms, which can be calculated from within-person variation in symptom evaluation tools. This led us to assess within-person variation in hypothyroid symptoms, in mood-related symptoms, and quality of life in patients with untreated SCH in order to support the recommended evaluations.

METHOD

The within-person coefficient of variation (CV) was estimated from 13 consecutive monthly evaluations in 15 patients with initial TSH between 5 and 12 mU/L and no trend in TSH.

RESULTS

The within-person CV was rather large for the Hospital Anxiety and Depression Scale (HADS) and Zulewski hypothyroid score at 41.6 and 60.9%, respectively. For quality of life the within-person CV was lower at 8.0% for the physical component summary and 8.7% for the mental component summary from the SF-36 questionnaire. The difference required between two measurements to detect a true change was 97% for mood-related symptoms (HADS) and 140% for hypothyroid symptoms. For quality of life (SF-36) the required difference was 20%.

CONCLUSION

Score differences of almost 100% and higher were required to support a true change in mood (HADS) and hypothyroid symptom scores in untreated SCH patients. For quality of life a true change was detected at a 20% difference in SF-36 scores. The hypothyroid score and HADS questionnaire do not seem useful for the evaluation of individuals.

Measuring HRQoL following heart valve surgery: the HeartQoL questionnaire is a valid and reliable core heart disease instrument

PURPOSE

Patient-reported health-related quality of life is a complementary healthcare outcome and important when assessing treatment efficacy. Using COSMIN methodological recommendations, this study evaluates the validity and reliability of a core heart disease-specific health-related quality of life questionnaire, the HeartQoL questionnaire (Danish version) in a sample of patients following heart valve surgery.

DESIGN

This project involved a cross-sectional validity study and a test-retest reliability study.

METHODS

Eligible patients completed the HeartQoL, the SF-36 health survey questionnaire, and the Hospital Anxiety and Depression Scale following heart valve surgery. Construct validity was tested using a priori hypotheses. Internal consistency reliability was assessed with Cronbach's alpha. An independent sample of patients participated in the test-retest study and reproducibility was determined with relative [intra-class correlation coefficient (ICC)] and absolute reliability [standard error of measurement (SEM) and smallest detectable change (SDC)].

RESULTS

Internal consistency was high with Cronbach's alpha ≥ 0.87. ICC was 0.86-0.92. SEM ranged from 0.17 to 0.26 points and SDC ranged from 0.5 to 0.7 points. Construct validity was confirmed with 87% of all a priori hypotheses for predicted variables.

CONCLUSIONS

The HeartQoL questionnaire demonstrates acceptable construct validity, internal consistency, and test-retest reproducibility in patients following heart valve surgery. Future studies should focus on assessing the responsiveness of the HeartQoL questionnaire over time and following heart valve surgery.

The association between life satisfaction, vitality, self-rated health, and risk of cancer

PURPOSE

Only few prospective studies have been conducted on the contribution of quality of life-related factors to the risk of cancer. The aim of this study was to investigate the prospective associations of three quality of life-related factors with the risk of cancer; life satisfaction, vitality, and self-rated health.

METHODS

In 2009-2011, 7189 participants in the Copenhagen Aging and Midlife Biobank were asked to rate their life satisfaction, their vitality, and their health. The study population was followed until the end of 2015 for registration of cancer in the Danish National Patient Register.

RESULTS

During the follow-up period, cancer was diagnosed in 312 individuals. Life satisfaction was not associated with the risk of cancer. Vitality was significantly associated with the risk of cancer, but the association became non-significant after adjustment for age, sex, socioeconomic position, and lifestyle factors. However, when additionally adjusting for life satisfaction, individuals who rated their vitality as low had a hazard ratio of 1.46 (95% confidence interval [CI] 1.04-2.07) for the development of cancer. Individuals who rated their health as poor had a hazard ratio of 1.70 (95% CI 1.27-2.26) for the development of cancer, compared with individuals with good, very good, or excellent self-rated health. The association remained significant after adjustment for basic confounders, life satisfaction, and vitality.

CONCLUSION

A better grasp of the significance of quality of life-related factors for the risk of cancer may be of great importance to population-based cancer prevention that aims to target early risk factors for development of cancer across widespread cancer sites.

Test-retest reliability and measurement error of the Danish WHO-5 Well-being Index in outpatients with epilepsy

Background

The generic questionnaire WHO-5 Well-being Index (WHO-5), which measures the construct of mental well-being has been widely used in several populations across countries. The questionnaire has demonstrated sufficient psychometric properties; however, the test- retest reliability of the WHO-5 scale has yet to be determined. The aim of this study was to evaluate the test-retest reliability and measurement error of the Danish WHO-5 Well-being Index for outpatients with epilepsy. A further aim was to evaluate whether the method of administration (web, paper, or a mixture of the two modalities) influenced the results.

Methods

Epilepsy outpatients aged ≥15 years from three outpatient clinics in Central Denmark Region were included from August 2016 to April 2017. The participants were randomly divided into four test-retest groups: web-web, paper-paper, web-paper, and paper-web. Test-retest reliability was assessed by intraclass correlation coefficients (ICC) and measurement error by calculating minimal detectable change (MDC) on the basis of the standard error of the measurement.

Results

A total of 554 patients completed the questionnaire at two time points. The median duration between test-retest was 22 days. The pooled test-retest reliability estimate was ICC 0.81 (95% CI 0.78; 0.84). The estimated MDC was 23.60 points (95% CI 22.27; 25.10). These estimates showed little variation across administration methods.

Conclusions

WHO-5 showed acceptable test-retest reliability in a Danish epilepsy outpatient population across different method of administration; however, the relatively large measurement error should be taken into account when evaluating changes in WHO-5 scores over time. Further research should be done to explore these findings.

Pain extent is more strongly associated with disability, psychological factors, and neck muscle function in people with non-traumatic versus traumatic chronic neck pain: a cross sectional study

BACKGROUND

Neck pain is presented with a variety of symptoms. Pain drawings are used in the clinical assessment of people with neck pain. Pain extent based upon pain drawings can be associated with different factors. However, the relation between pain extent and function limitations in people with neck pain is unknown.

AIM

The aim of this study was to explore the associations between pain extent extracted from pain drawings, and self-reported neck pain related disability, quality of life, depression, self-reported neck function, cervical muscle function, and range of motion in a chronic neck pain population and possible differences depending on the onset of pain being traumatic or not.

DESIGN

Observational cross-sectional study.

SETTING

Primary and secondary healthcare.

POPULATION

People with chronic neck pain (N.=200) of traumatic (N.=120) or non-traumatic (N.=80) origin.

METHODS

Outcome measures: Pain extent, Short Form 36 Health Survey Physical and Mental Component Summary (SF36-PCS/MCS), TAMPA Scale of Kinesiophobia (TSK), Beck Depression Inventory-II (BDI-II), Neck Disability Index (NDI), Craniocervical Flexion Test (CCFT), Cervical Extension Test (CE), and Cervical Range of Motion (ROM). Correlations were calculated using Spearman or Pearson correlation coefficients. Correlation between pain extent and outcomes were calculated for all participants collectively and then separately for those with a traumatic versus non-traumatic neck pain.

RESULTS

Overall, significant positive correlations were observed between pain extent and NDI (r=0.33; P<0.001), BDI-II (r=0.29; P<0.001), CCFT (r=-0.24; P=0.001) and CE (r=-0.19; P=0.006). No difference was observed in pain extent between patients with traumatic (mean: 7.6±6.7%) and non-traumatic onset (7.4±6.8%). Pain extent correlated moderately with NDI, BDI-II, TSK, CCFT and CE in those with non-traumatic onset, but weakly with NDI, BDI-II, CCFT and CE in those with trauma-induced chronic neck pain.

CONCLUSIONS

Pain extent is correlated with patient-reported neck function, depression and muscle test performance in people with chronic neck pain. These correlations were strongest in those with non-traumatic neck pain.

CLINICAL REHABILITATION IMPACT

Patients presenting with larger pain areas show poorer psychological and physical function. Pain drawings can therefore indicate a need for addressing these functions in management of a person with chronic neck pain.

Telemonitored exercise-based cardiac rehabilitation improves physical capacity and health-related quality of life

Introduction

Cardiac rehabilitation improves physical capacity, health-related quality of life, and reduces morbidity and mortality among cardiac patients. Telemonitored exercise-based cardiac rehabilitation may innovate existing programmes and increase participation rates.

Objective

The purpose of this study was to investigate if telemonitored exercise-based cardiac rehabilitation improves physical capacity, muscle endurance, muscle power, muscle strength and health-related quality of life in cardiac patients.

Methods

A follow-up study on moderate risk patients with ischaemic heart and heart valve disease referred to a 12-week telemonitored exercise-based cardiac rehabilitation intervention at Aarhus University Hospital (Denmark). Participants were encouraged to exercise 60 min three times weekly with moderate/high intensity for 20 min per session. Intensity and duration of training sessions were visualised on a smartphone and uploaded to a website. Participants received individual feedback from physiotherapists on their training efforts by telephone/email. Outcome measures were changes in physical capacity (peak oxygen uptake), muscle endurance, power, and strength, and health-related quality of life between baseline end of telemonitored exercise-based cardiac rehabilitation intervention, and at six and 12 months after end of telemonitored exercise-based cardiac rehabilitation.

Results

Thirty-four participants completed telemonitored exercise-based cardiac rehabilitation. We identified a significant increase in peak oxygen uptake of 10%, in muscle endurance of 17%, in muscle power of 7%, and in muscle strength of 10% after the telemonitored exercise-based cardiac rehabilitation programme. Health-related quality of life was significantly improved by 19% in the physical and 17% in the mental component scores. We found no significant improvement in peak oxygen uptake between baseline and 12 months follow-up, but a significant improvement in muscle endurance (0.3 watts/kg, 95% confidence interval; 0.2–0.4), muscle power (0.4 watts/kg; 0.2–0.5), muscle strength (0.5 N/m/kg; 0.1–0.9), physical health-related quality of life (five points; 2–8) and mental health-related quality of life (six points; 3–9).

Discussion

This study demonstrated that the self-elected type of physical exercise in cardiac rehabilitation with telemonitoring improved all outcome measures both on the short and long-term, except for peak oxygen uptake at 12 months follow-up.
