- Chronic pain-related sickness absence is an enormous socioeconomic burden globally. Optimized interventions are reliant on a lucid understanding of the distribution of social insurance benefits and their predictors. This register-based observational study analyzed data for a 7-year period from a population-based sample of 44,241 chronic pain patients eligible for interdisciplinary treatment (IDT) at specialist clinics. Sequence analysis was used to describe the sickness absence over the complete period and to separate the patients into subgroups based on their social insurance benefits over the final 2 years. The predictive performance of features from various domains was then explored with machine learning-based modeling in a nested cross-validation procedure. Our results showed that patients on sickness absence increased from 17% 5 years before to 48% at the time of the IDT assessment, and then decreased to 38% at the end of follow-up. Patients were divided into 3 classes characterized by low sickness absence, sick leave, and disability pension, with eight predictors of class membership being identified. Sickness absence history was the strongest predictor of future sickness absence, while other predictors included a 2008 policy, age, confidence in recovery, and geographical location. Information on these features could guide personalized intervention in the specialized healthcare. PERSPECTIVE: This study describes sickness absence in patients who visited a Swedish pain specialist interdisciplinary treatment clinic during the period 2005 to 2016. Predictors of future sickness absence are also identified that should be considered when adapting IDT programs to the patient's needs.

- Recent research has highlighted a need for the psychometric evaluation of instruments targeting core domains of the pain experience in chronic pain populations. In this study, the measurement properties of Short Form-36 Health Survey (SF-36),EuroQol 5-dimensions (EQ-5D) and Hospital Anxiety and Depression Scale (HADS) were analyzed within the item response-theory framework based on data from 35,908 patients. To assess the structural validity of these instruments, the empirical representations of several conceptually substantiated latent structures were compared in a cross-validation procedure. The most structurally sound representations were selected from each questionnaire and their internal consistency reliability computed as a summary of their precision. Finally, questionnaire scores were correlated with each other to evaluate their convergent and discriminant validity. Our results supported that SF-36 is an acceptable measure of 2 independent constructs of physical and mental health. By contrast, although the approach to summarize the health-related quality of life construct of EQ-5D as a unidimensional score was valid, its low reliability rendered practical model implementation of doubtful utility. Finally, rather than being separated into 2 subscales of anxiety and depression, HADS was a valid and reliable measure of overall emotional distress. In support of convergent and discriminant validity, correlations between questionnaires showed that theoretically similar traits were highly associated, whereas unrelated traits were not. Our models can be applied to score SF-36 and HADS in chronic pain patients, but we recommend against using the EQ-5D model due to its low reliability. These results are useful for researchers and clinicians involved in chronic pain populations because questionnaires' properties determine their discriminating ability in patient status assessment.

- Background Interdisciplinary treatment (IDT) is an internationally recommended intervention for chronic pain, despite inconclusive evidence of its effects on sickness absence. Methods With data from 25,613 patients in Swedish specialist healthcare, we compared sickness absence, in the form of both sick leave and disability pensions, over a 5-year period between patients either allocated to an IDT programme or to other/no interventions (controls). To obtain population-average estimates, a Markov multistate model with theory-based inverse probability weights was used to compute both the proportion of patients on sickness absence and the total sickness absence duration. Results IDT patients were more likely than controls to receive sickness absence benefits at any given time (baseline: 49% vs. 46%; 5-year follow-up: 36% vs. 35%), and thereby also had a higher total duration, with a mean (95% CI) of 67 (87, 48) more days than controls over the 5-year period. Intriguingly, sick leave was higher in IDT patients (563 [552, 573] vs. 478 [466, 490] days), whereas disability pension was higher in controls (152 [144, 160] vs. 169 [161, 178] days). Conclusion Although sickness absence decreased over the study period in both IDT patients and controls, we found no support for IDT decreasing sickness absence more than other/no interventions in chronic pain patients. Significance In this large study of chronic pain patients in specialist healthcare, sickness absence is compared over a 5-year period between patients in an interdisciplinary treatment programme and other/no interventions. Sickness absence decreased over the study period in bothgroups; however, there was no support forthat it decreased more with interdisciplinary treatment than alternative interventions.

- Objective: To explore the associations between habitual self-reported physical activity, pain sensitivity and patient-reported outcomes (including pain intensity) in patients with chronic pain. Design: Cross-sectional, experimental study. Subjects: Patients (n = 78), age range 18-65 years, with different chronic pain conditions (> 3 months) were compared with age- and sex-matched healthy controls (n = 98). Methods: Multivariate correlations between selfreported physical activity, pressure pain sensitivity, and patient-reported outcome measures were assessed. Results: Lower perceived health status (p <0.001, Cohens d =2.34), higher levels of depression (p< 0.001, Cohens d = 1.77), and lower pain tolerance threshold (p < 0.001, Cohens d = 1.66) were the most prominent variables discriminating patients from controls. In patients, bivariate and multivariate analyses showed that higher pressure pain tolerance was associated with male sex, lower pain intensity and fewer painful regions, higher self-efficacy and more self-reported physical activity, but not with lower levels of anxiety and depression. Conclusion: Pain tolerance thresholds, as well as degree of depression and perceived health status discriminated between patients and controls, and there was an association between pain tolerance thresholds and level of self-reported physical activity in patients. This study highlights the importance of further research into how increased physical activity may improve pain sensitivity in patients with chronic pain.

- OBJECTIVE: To investigate prognostic factors for physical and emotional functioning following interdisciplinary multimodal pain rehabilitation, by targeting patients' baseline characteristics and health measures.METHODS: A prospective cohort of 2,876 patients from 38 specialist clinics across Sweden, who were completing interdisciplinary multimodal pain rehabilitation programmes, was followed through the Swedish Quality Registry for Pain Rehabilitation, from initial assessment to 12-month follow-up. Using logistic regression, baseline data were regressed to predict improvement in Physical functioning and Emotional functioning, fused by principal component analyses using the 36-item Short Form Health Survey (SF-36) and the Hospital Anxiety and Depression Scale (HADS).RESULTS: Employment status emerged as having the largest effect sizes in both Physical functioning and Emotional functioning; Working: odds ratio (OR) 2.05 (95% confidence interval (95% CI) 1.64-2.56) and OR 1.59 (95% CI 1.27-1.98), respectively. Strong beliefs in restored health, better initial emotional health, lower levels of pain and pain interference, and younger age all predicted Physical functioning. European origin, higher levels of general activity, and sense of life control all predicted Emotional functioning. Worse initial physical and emotional health predicted the corresponding dependent outcomes.CONCLUSION: Employment was consistently found to be an important prognostic factor, suggesting the significance of avoiding delay in interdisciplinary multimodal pain rehabilitation. A positive treatment expectancy was of importance. In general, multidimensional measures indicated that better initial status was more favourable; however, inconsistency implies a complex prognostic picture.

Tidskriftsartikel (refereegranskat)abstract
- Chronic pain is a leading cause of disability globally. Interdisciplinary multimodal pain rehabilitation (IMPR) targets pain with a bio-psycho-social approach, often delivered as composite programs. However, evidence of optimal program duration for the rehabilitation to succeed remains scarce. This study evaluated the effectiveness of different duration IMPR-programs-using within- and between-effects analyses in a pragmatic multicenter register-based controlled design. Using the Swedish Quality Registry for Pain Rehabilitation, data from fifteen clinics specialized in chronic pain rehabilitation across Sweden were retrieved. Participants were patients with chronic musculoskeletal pain who had taken part in short (4-9 weeks; n = 924), moderate (10 weeks; n = 1379), or long (11-18 weeks; n = 395) IMPR programs. Longitudinal patient-reported outcome data were assessed at baseline, post-intervention, and at a 12-month follow-up. Primary outcomes were health-related quality of life, presented as perceived physical and mental health (SF-36). Secondary outcomes included the Hospital Anxiety and Depression Scale (HADS), pain intensity (NRS 0-10), the Multidimensional Pain Inventory (MPI), and perceived health (EQ-5D). Overall, all groups showed improvements. No clinically important effect emerged for different duration IMPR. In conclusion, while our results showed that patients following IMPR report improvement across a bio-psycho-social specter, a longer program duration was no more effective than a shorter one.

Insomnia Symptoms in Chronic Pain : Clinical presentation, risk and treatment
- 2021

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- In recent years, chronic and recurrent pain have gained interest as distinct conditions interacting both with peripheral and central parts of the nervous system as well as with the immune system. The risk of getting affected by abnormal pain modulation i.e., chronic pain is not equally distributed in the population and the search for risk factors is therefore of interest. One potential risk factor for chronic pain is insomnia symptoms i.e., difficulties falling asleep or maintaining sleep. In turn, insomnia symptoms are overrepresented in persons with chronic pain. Common current pain treatments lead to limited improvement of insomnia symptoms calling for treatments specifically directed to improve sleep. The overall aim of this thesis is therefore to investigate the distribution of insomnia severity in patients seeking specialized care for chronic pain, to investigate the role of insomnia severity as a risk factor for spreading of pre-existing pain, and to evaluate potential treatments for insomnia symptoms comorbid to chronic pain.Study I highlighted the high prevalence rates of insomnia symptoms in patients with chronic pain conditions. Roughly, insomnia was six times more common in our sample compared to the general population. We also showed that there were weak connections between insomnia symptoms and other variables (primarily psychological symptoms and pain intensity). In Study II physical exercise was more efficacious than Acceptance and Commitment Therapy-based stress management and the active control group in reducing insomnia symptoms and pain intensity short term. Improvements in physical exercise were largely maintained after twelve months but pain intensity had then also declined in the control group. No improvements in the Acceptance and Commitment Therapy-based stress management remain significant when an intention to treat principles were applied. In Study III, a dose-dependent increase in risk for spreading of pain was confirmed in subjects reporting moderate and severe insomnia symptoms. Though, there was no increase in the risk of pain spreading in subjects reporting sub-threshold insomnia symptoms (according to Insomnia Severity Index). In Study IV patients in the Internet-delivered Cognitive Behavioural Therapy for insomnia group, showed a more rapid improvement in insomnia symptoms than patients in the internet-delivered applied relaxation. The effect of Cognitive Behavioural Therapy for insomnia had declined slightly after six months and the Applied Relaxation group had continued to improve, leading to a comparable outcome on the Insomnia Severity Index at six-month follow-up.In conclusion, insomnia symptoms are common in patients seeking specialized pain care. High levels of insomnia symptoms increase the risk of spreading of pre-existing pain and this in a dose-dependent manner. Physical exercise has significant, but not clinically meaningful effects on pain intensity and insomnia symptoms. Internet-delivered Cognitive Behavioral Therapy for insomnia leads to a more rapid reduction of insomnia symptoms compared to applied relaxation, although long-term effects are uncertain

Tidskriftsartikel (refereegranskat)abstract
- Objectives: Internet-delivered psychological interventions can be regarded as evidence-based practices and have been implemented in psychiatric and somatic care at primary and specialist levels. However, challenges as low adherence and poor routinization, have arisen during attempts to implement internet-delivered interventions in chronic pain settings. Internet-delivered Acceptance and Commitment Therapy (IACT) has been found to be helpful for chronic pain patients and might aid in developing pain rehabilitation services. However, the integration of IACT into standard health care has not yet been described from an implementation science perspective. The aim of this hybrid 1 effectiveness-implementation study was to evaluate the process of implementing IACT in a pain rehabilitation setting, to guide future implementation initiatives.Methods: In this retrospective study we described actions taken during an implementation initiative, in which IACT was delivered as part of an interdisciplinary pain rehabilitation program (IPRP) at a specialist level clinic. All documents relevant to the study were reviewed and coded using the Quality Improvement Framework (QIF), focusing on adoption, appropriateness and sustainability.Results: The QIF-analysis of implementation actions resulted in two categories: facilitators and challenges for implementation. Sustainability may be facilitated by sensitivity to the changing needs of a clinical setting and challenged by unfitting capacity building. Appropriateness might be challenged by an insufficient needs assessment and facilitated by aligning routines for communication with the clinics existing infrastructure. Adoption may be facilitated by staff key champions and an ability to adapt to occurring hurdles. Possible influential factors, hypotheses and key process challenges are presented in a logic model to guide future initiatives.Conclusions: Sustainable implementation may depend on both the continuity of facilitating implementation actions and flexibility to the changing needs and interests of patients, caregivers and organization. We conclude that the use of theories, models and frameworks (TMF) as well as a logic model may ease design, planning and evaluation of an implementation process. Lastly, we suggest that IACT may be appropriate for IPRP when given before or after IPRP, focusing on psychiatric comorbidities.
