Interventions to improve return to work in depressed people

Prompt Mental Health Care (PMHC): work participation and functional status at 12 months post-treatment

BACKGROUND

Anxiety and depression are associated with substantial functional impairment. Prompt Mental Health Care (PMHC), the Norwegian adaptation of IAPT is currently piloted across Norway, as a means to improve access to evidence-based care for adults with anxiety disorders (including subthreshold cases) and minor to moderate depression. The aims of the current paper were to examine the change in work status and functional status from pre- to post-treatment and 12 months post-treatment among clients at the first 12 PMHC pilot sites, and whether degree of change differed across sociodemographic characteristics.

METHODS

A prospective cohort design was used, including working age clients receiving treatment between October 2014 and December 2016 (n = 1446, participation rate = 61%). Work status and functional status were self-reported, the latter by the Work and Social Adjustment Scale (WSAS). Changes in work status and WSAS score were examined through multilevel models based on maximum likelihood estimation. Likelihood ratio tests were performed to determine whether the interaction between time and the respective background variables were statistically significant.

RESULTS

A substantial increase in regular work participation was observed from pre- to post-treatment, which further had increased at 12 months post-treatment. The increase was driven by a corresponding reduction in proportion of clients working and receiving benefits (OR 0.38 [0.29-0.50] baseline to final treatment, OR = 0.19 [0.12-0.32] final treatment to 12-months post-treatment), while no statistically significant change was observed in proportion out of work. Large improvement (ES = - 0.89) in WSAS score was observed from pre- to post treatment. WSAS score at 12 months post-treatment remained at the post-treatment level.

CONCLUSIONS

Previous research has shown substantial symptom improvement among clients receiving treatment in PMHC. The current findings indicate that PMHC might also be able to aid adults struggling with mild to moderate anxiety and depression in returning to usual level of functioning. The degree to which the observed improvements are attributable to the treatment need nonetheless to be confirmed in a trial including a control group and with more complete follow-up data from registries.

Identifying Individuals at High Risk for Permanent Disability From Depression and Anxiety

Mental illnesses, among which depression and anxiety are most common, are the leading cause for permanent disability. It is of interest to know what case characteristics determine if a person returns to the work force in spite of mental illness to tailor specific interventions. So far, there has been little research into this field. In the present study a sample of 202 workers who had permanent disability due to depression/anxiety were followed-up on. 22% started some kind of work during follow-up in a period of 30 to 75 months. Logistic regression analyses showed that quick progression into disability, short period of disability, younger age, adequacy of income replacement through insurance benefits and no previous disability predicted return to work. These findings also allow to identify individuals at high risk for progression into permanent disability that can benefit from supporting interventions.

Re-work Program in Japan-Overview and Outcome of the Program

Background: The objective of this study was to examine the effect of the Japanese re-work program (RP) to aid in recurrent sick leave prevention. Methods: A multicenter retrospective cohort research was conducted for workers who returned to work (RTW) after sick leave due to mood disorder. Work continuation for subjects who RTW after RP participation and treatment as usual (TAU) and subjects who received TAU only were compared. The Kaplan-Meier method and Cox proportional hazard models were utilized. Additionally, propensity score matching was conducted to control for possible confounds. Results: Log-rank test of overall cohort (n = 323) showed that work continuation of RP + TAU subjects was significantly better compared to that of TAU-only subjects (p = 0.001). Multivariate analysis found a hazard rate of recurrent sick leave for TAU-only subjects of 2.121 (p = 0.001, 95% CI: 1.360-3.309). Additionally, the propensity score-matched cohort (n = 100) had similar differences (p = 0.008), with a hazard ratio of recurrent sick leave of 2.871 (p = 0.009, 95% CI: 1.302-6.331) for TAU-only subjects. Limitations: Only workers who RTW after sick leave were targeted, and no examination was made considering cases who dropped out from RP or TAU. Moreover, the sample was a non-randomized controlled trial, with propensity score matching performed. However, there was an inability to retrieve and adjust for working environment background factors after RTW. Conclusions: Work continuation of subjects with RP was observed to be significantly better, suggesting that the RP was effective for recurrent sick leave prevention.

Networking of occupational health care units promotes reduction of permanent disability pensions among workers they care: A register-based study controlled by benchmarking with a 5-year follow-up

OBJECTIVES

Early retirement due to disability is a problem in Finland. That causes pension costs that are heavy for the society. This study was designed to find out whether a quality network can support the reduction in incident disability pensions and promote a shift from full to partial disability pensions.

METHODS

The study population (N = 41 472 in 2016) consisted of municipal employees whose occupational health care (OHC) was provided by the members of the Finnish Occupational Health Quality Network (OQN). The comparison population consisted of all municipality employees whose OHC was provided by non-members of the OQN (N = 340 479 in 2016). The outcomes were measured by comparing the trends in incident disability pensions of full and partial permanent pension and full and partial provisional pension, partial/full pension indexes from 2011 to 2016 according to the principles of Benchmarking Controlled Trials. Linear regression models were used to explore the dynamics of different pension forms. Regression coefficients were calculated to show the average change per year.

RESULTS

The incidence of permanent disability pensions decreased faster in the study population (P for trend .03) and the study group showed a stronger shift from full to partial permanent pensions (P for trend <.001).

CONCLUSION

Quality networking between OHC units including common goal setting, systematic quality improvement, and repeated quality measurements decreased new permanent disability pensions and increased partial permanent pensions. Such changes are important while thriving for increased work participation.

Interpersonal Psychotherapy vs. Treatment as Usual for Major Depression Related to Work Stress: A Pilot Randomized Controlled Study

Background: Depressive disorders are among the leading causes of sick leave and long-term work incapacity in most modern countries. Work related stress is described by patients as the most common context of depression. It is vital to know what types of treatments are effective in improving work related problems and occupational health. However, there is only limited evidence on work-focused interventions. Methods: The aim of our study was to evaluate the feasibility and generate first data on the effectiveness of Interpersonal Psychotherapy (IPT) adapted as a group program to focus on the work context (W-IPT). In total, 28 outpatients (22 women; M = 49.8 years old) with Major Depressive Disorder related to work stress were randomized to 8 weekly group sessions of W-IPT or to treatment as usual (TAU; guideline oriented treatment). Primary endpoint was the Hamilton Rating Scale for Depression (HRSD-24) score. Key secondary endpoints were, among others, Beck Depression Inventory (BDI-II), Work Ability Index (WAI), Return to Work Attitude (RTW-SE), and the Effort-Reward-Imbalance (ERI). In addition, we evaluated the participants' overall satisfaction with the W-IPT program by two items. A follow-up assessment was conducted 3 months after end of acute treatment. Results: W-IPT was significantly more effective than TAU in reducing clinician-assessed depressive symptoms at follow-up (HRSD-24 W-IPT/TAU: M = 6.6/12.0, SE: 1.46/2.17, t_{(df = 1)} = -2.24, p = 0.035, d = 0.79) and self-assessed depression (BDI-II W-IPT/TAU post-treatment: M = 8.8/18.8, SE: 1.69/2.70, t_{(df = 1)} = -3.82, p = 0.001, d = 1.28; follow-up: M = 8.8/16.1, SE: 1.62/2.26, t_{(df = 1)} = -2.62, p = 0.015, d = 0.99). Furthermore, W-IPT was superior in improving work-ability (WAI), return-to-work attitude (RTW-SE), and the effort-reward-ratio (ERI). No dropouts were observed in both groups. The vast majority (89 percent) of participants in the W-IPT condition were "very satisfied" with the program, although wishing for a greater number of sessions (75 percent). Conclusions: A work-focused IPT program for the treatment of depression associated to work stress was feasible and highly acceptable. W-IPT turned out to be more effective than standard treatment in reducing depression and work-related problems. However, further evidence in a multicenter trial extending this pilot study is necessary.

Newly educated care managers' experiences of providing care for persons with stress-related mental disorders in the clinical primary care context

Objective

Our aim was to explore how the care managers put the complex care manager task into practice and how they perceived their task, which was to facilitate effective, person-centred treatment for stress-related disorder concordant with evidence-based guidelines in primary care.

Design

This was a qualitative study using examination reports from the course for care managers. Systematic text condensation according to Malterud was used for the analysis.

Setting

Primary health care centres

Subject

Twenty-eight newly educated care managers in primary health care participated in the study. The median age was 50 (31–68) years. Twenty-seven were women and one was a man. Twenty-one were employed as nurses and seven as counsellors.

Results

The informants perceived the role as care manager as meaningful but at times complicated. To participate in teams and to work closely with the general practitioner was experienced as important. The co-ordinating function was emphasised as especially important, as well as the increased continuity in care. The dual role as care manager and counsellor was sometimes experienced as problematic.

Conclusion

The informants took advantage of the knowledge they had attained during the course. They perceived themselves as being a bridge between patients and other professionals. The result of having dual roles at the primary health care centre unexpectedly revealed difficulties for some professionals. The nurses seemed more familiar with the new way of working.

Effectiveness of internet-delivered cognitive behavioural therapy in reducing sickness absence among young employees with depressive symptoms: study protocol for a large-scale pragmatic randomised controlled trial

INTRODUCTION

Depression is a highly prevalent condition with typical onset in early adulthood. Internet-delivered cognitive behavioural therapy (iCBT) is a promising cost-effective and more widely available alternative to face-to-face CBT. However, it is not known whether it can reduce sickness absence in employees showing depressive symptoms. The randomised controlled trial component of the DAQI (Depression and sickness absence in young adults: a quasi-experimental trial and web-based treatment intervention) project aims to investigate if iCBT is effective in reducing sickness absence compared with care as usual (CAU) among young employees with depressive symptoms in primary care provided in an occupational health setting.

METHODS AND ANALYSIS

This study will use a randomised controlled single-centre service-based trial of an existing iCBT programme (Mental Hub iCBT for Depression) to evaluate whether or not this treatment can reduce the number of sickness absence days in public sector employees aged 18-34 years who present at the occupational health service with mild depressive symptoms (score ≥9 on the Beck Depression Inventory-IA). Control participants will be offered CAU, with no constraints regarding the range of treatments. The active condition will consist of seven weekly modules of iCBT, with support from a web therapist. Primary outcome will be participants' all-cause sickness absence as indicated in employer's and national administrative records up to 6 months from study entry. Secondary outcomes relating to long-term sickness absence (over 11 calendar days) for mental and musculoskeletal disorders and psychotropic medication use will be obtained from the Finnish Social Insurance Institution's administrative records; and short sickness absence spells (up to 11 calendar days) will be extracted from employer's records. Analyses will be conducted on an intention-to-treat basis.

ETHICS AND DISSEMINATION

The Coordinating Ethics Committee of the Hospital District of Helsinki and Uusimaa has approved the study (HUS/974/2019). The results will be published in peer-reviewed scientific journals and in publications for lay audience.

Obstacles to returning to work with chronic pain: in-depth interviews with people who are off work due to chronic pain and employers

Background

The global burden of chronic pain is growing with implications for both an ageing workforce and employers. Many obstacles are faced by people with chronic pain in finding employment and returning to work after a period of absence. Few studies have explored obstacles to return-to-work (RTW) from workers’ and employers’ perspectives. Here we explore views of both people in pain and employers about challenges to returning to work of people who are off work with chronic pain.

Methods

We did individual semi-structured interviews with people who were off work (unemployed or off sick) with chronic pain recruited from National Health Service (NHS) pain services and employment services, and employers from small, medium, and large public or private sector organisations. We analysed data using the Framework method.

Results

We interviewed 15 people off work with chronic pain and 10 employers. Obstacles to RTW for people with chronic pain spanned psychological, pain related, financial and economic, educational, and work-related domains. Employers were concerned about potential attitudinal obstacles, absence, ability of people with chronic pain to fulfil the job requirements, and the implications for workplace relationships. Views on disclosure of the pain condition were conflicting with more than half employers wanting early full disclosure and two-thirds of people with chronic pain declaring they would not disclose for fear of not getting a job or losing a job. Both employers and people with chronic pain thought that lack of confidence was an important obstacle. Changes to the job or work conditions (e.g. making reasonable adjustments, phased return, working from home or redeployment) were seen by both groups as facilitators. People with chronic pain wanted help in preparing to RTW, education for managers about pain and supportive working relationships.

Conclusions

People with chronic pain and employers may think differently in terms of perceptions of obstacles to RTW. Views appeared disparate in relation to disclosure of pain and when this needs to occur. They appeared to have more in common regarding opinions about how to facilitate successful RTW. Increased understanding of both perspectives may be used to inform the development of improved RTW interventions.

A psychosocial theory of sick leave put to the test in the European Working Conditions Survey 2010-2015

PURPOSE

In the present investigation a psychosocial theory of sick leave is proposed which integrates work-related determinants, health effects of particular work characteristics, and workers' health status. In addition, the theory explicitly formulates a series of mediators and moderators of the associations between work-related determinants and sick leave. On the basis of the theoretical assumptions and previous research findings, a series of research hypotheses are investigated with survey data.

METHODS

The study is based on data from the European Working Conditions Survey 2010 and 2015 (n = 59,790). The research hypotheses are investigated by means of generalised linear mixed models within the framework of hierarchical Bayesian regression models and Markov Chain algorithms. The theory is assessed by estimating three so-called hurdle models, which take into account the excess zeros usually observed in sick leave rates.

RESULTS

In general, the findings provide evidence of the adequacy of the theory explaining the observed variation of sick-leave rates. Several biomechanical and psychosocial characteristics of the working environment, occupation, age, and the subjective assessment of health status were found to be strongly associated with both the likelihood of being in sick leave and the length of sick-leave spells.

CONCLUSIONS

The theory and the findings of the present study may serve as a basis for the development and implementation of occupational health interventions aiming to reduce sick-leave rates in organisations.

Targets and outcomes of psychotherapies for mental disorders: an overview

It is not yet clear what mental disorders are and what are the causal pathways that lead to them. That makes it difficult to decide what the targets and outcomes of psychotherapies should be. In this paper, the main types of targets and outcomes of psychotherapies are described, and a brief overview is provided of some of the main results of research on these types. These include symptom reduction, personal targets and outcomes from the patient's perspective, improvement of quality of life, intermediate outcomes depending on the theoretical framework of the therapist, negative outcomes to be avoided, and economic outcomes. In line with the dominance of the DSM and ICD systems for diagnoses, most research has been focused on symptom reduction. This considerable body of research, with hundreds of randomized trials, has shown that for most mental disorders effective psychotherapies are available. There is also research showing that psychotherapies can result in improvement of quality of life in most mental disorders. However, relatively little research is available on patient-defined outcomes, intermediate outcomes, negative outcomes and economic outcomes. Patients, relatives, therapists, employers, health care providers and society at large each have their own perspectives on targets and outcomes of psychotherapies. The perspective of patients should have more priority in research, and a standardization of outcome measures across trials is much needed.

Facilitators, barriers and ethical values related to the coordination of return-to-work among employees on sick leave due to common mental disorders: a protocol for a qualitative study (the CORE-project)

INTRODUCTION

Diagnoses related to common mental disorders such as anxiety, depression, adjustment disorders and stress-related disorders are one of the leading causes of long-term sick leave for both women and men in Organisation for Economic Co-operation and Development countries. To increase the rate of return-to-work workplace involvement in a coordinated return-to-work process has been included in recent best practice guidelines. This form of cooperation is a complex process, involving political structures and a wide range of stakeholders. The study's first aim is to describe facilitators and barriers to the coordination of return-to-work from the perspectives of: (A) employees on sick leave due to common mental disorders, (B) employers, (C) rehabilitation coordinators, (D) physicians and (E) other stakeholders. The second aim is to identify ethical issues that arise in the coordination of return-to-work and analyse how these can be resolved.

METHODS AND ANALYSIS

The study has a qualitative design using interviews with employees on sick leave due to common mental disorders, employers, rehabilitation coordinators, physicians and other stakeholders. The study is conducted in the Swedish primary healthcare. Employees, employers and rehabilitation coordinators are recruited via primary healthcare centres. Rehabilitation coordinators receive information about the study and those who consent to participation are asked to recruit employees and employers. Interview guides have been developed from the consolidated framework for implementation research and ethical values and norms found in Swedish healthcare, social services and workplace legislation. Data will be analysed with qualitative content analysis reflecting manifest and latent content, and ethical issues will be analysed by means of reflective equilibrium methodology.

ETHICS AND DISSEMINATION

The study was approved by the Regional Ethical Review Board in Stockholm, Sweden (Reg.no 2018/677-31/2 and 2018/2119-32). The findings will be disseminated through publication in scientific journals, social media, seminars and national and international conferences.

Evidence available for patient-identified priorities in depression research: results of 11 rapid responses

OBJECTIVES

Patient priority setting projects (PPSPs) can reduce research agenda bias. A key element of PPSPs is a review of available literature to determine if the proposed research priorities have been addressed, identify research gaps, recognise opportunities for knowledge translation (KT) and avoid duplication of research efforts. We conducted rapid responses for 11 patient-identified priorities in depression to provide a map of the existing evidence.

DESIGN

Eleven rapid responses.

DATA SOURCES

Single electronic database (PubMed).

ELIGIBILITY CRITERIA

Each rapid response had unique eligibility criteria. For study designs, we used a stepwise inclusion process that started with systematic reviews (SRs) if available, then randomised controlled trials and observational studies as necessary.

RESULTS

For all but one of the rapid responses we identified existing SRs (median 7 SRs per rapid response, range 0-179). There were questions where extensive evidence exists (ie, hundreds of primary studies), yet uncertainties remain. For example, there is evidence supporting the effectiveness of many non-pharmacological interventions (including psychological interventions and exercise) to reduce depressive symptoms. However, targeted research is needed that addresses comparative effectiveness of promising interventions, specific populations of interest (eg, children, minority groups) and adverse effects.

CONCLUSIONS

We identified an extensive body of evidence addressing patient priorities in depression and mapped the results and limitations of existing evidence, areas of uncertainty and general directions for future research. This work can serve as a solid foundation to guide future research in depression and KT activities. Integrated knowledge syntheses bring value to the PPSP process; however, the role of knowledge synthesis in PPSPs and methodological approaches are not well defined at present.

Return-to-Work Following Depression: What Work Accommodations Do Employers and Human Resources Directors Put in Place?

The magnitude of economic and social costs related to common mental disorders has a profound impact on the workplace. Returning to work following depression is, therefore, a major issue for all stakeholders involved (employee, employer, human resources director, union, physician, etc.). Considering their role in the organization, Human Resources Directors (HRD) and employers have a decisive impact on the return-to-work (RTW) process. Purpose This study aims to determine which RTW accommodations are implemented, following depression, by one of the central stakeholders: HRD and employers. Methods 219 HRD/employers participated in a semi-structured telephone interview about RTW of employees after depression. From that interview, the question related to this article was: Do you put in place work accommodations for employees after a sick leave due to depression (yes or no)? If their response was positive, we asked: If yes, what were the work accommodations? Results 170 HRD/employers specified accommodations. The most common categories identified were related to: work schedule, task modifications, job change and work environment change. Accommodations directly related to the employee or the colleagues were considerably less mentioned and those concerning other RTW stakeholders, including supervisor, were almost absent. Conclusion Our results suggest that accommodations directly related to work aspects seemed to predominate in our sample of HRD/employers when an employee returned-to-work following depression. The relational aspect and the involvement of the different stakeholders are also not prioritized to accommodate the RTW. These results contrast with employer best practice guidelines for the RTW of workers with common mental disorders.

Expanding Individual Placement and Support to Populations With Conditions and Disorders Other Than Serious Mental Illness

OBJECTIVE

A systematic review of studies of individual placement and support (IPS) for populations other than those with serious mental illness was conducted.

METHODS

The authors searched three electronic databases (PubMed, Web of Science, and Scopus) for studies of IPS and modified IPS. Eligibility criteria for the systematic review included randomized controlled trials with prospective data collection on competitive employment rate and at least 10 study participants from a well-defined population other than people with serious mental illness. Results were compiled for competitive employment rates, IPS fidelity, and other outcomes.

RESULTS

Three clinical groups other than people with serious mental illness have been studied: people with psychiatric disorders other than serious mental illness, people with substance use disorders, and people with musculoskeletal or neurological disorders. Nine controlled trials with a total of 2,902 participants included six trials with people who had psychiatric disorders other than serious mental illness, two with people who had substance use disorders, and one with people who had spinal cord injuries. In eight studies, results for competitive employment rates significantly favored IPS. Meta-analysis yielded an overall weighted odds ratio of 2.23 (95% confidence interval=1.53-3.24, p<.001). Findings for other employment outcomes also favored IPS, but findings on symptom reduction and quality of life were inconsistent. The strongest (and only replicated) findings were for veterans with posttraumatic stress disorder (PTSD). Methodological limitations included small samples, major modifications to IPS fidelity, and short follow-up periods.

CONCLUSIONS

IPS, often with modifications, is a promising employment intervention for several populations in addition to people with serious mental illnesses. The strongest evidence pertains to veterans with PTSD. IPS should be offered to these veterans. Research on other populations, including people with anxiety, depression, substance use disorder, musculoskeletal or neurological conditions, or pain syndromes, needs development, amplification, and replication.

Patient Perspective of Cognitive Symptoms in Major Depressive Disorder: Retrospective Database and Prospective Survey Analyses

BACKGROUND

Major depressive disorder (MDD) is a common and burdensome condition. The clinical understanding of MDD is shaped by current research, which lacks insight into the patient perspective.

OBJECTIVE

This two-part study aimed to generate data from PatientsLikeMe, an online patient network, on the perception of cognitive symptoms and their prioritization in MDD.

METHODS

A retrospective data analysis (study 1) was used to analyze data from the PatientsLikeMe community with self-reported MDD. Information on patient demographics, comorbidities, self-rated severity of MDD, treatment effectiveness, and specific symptoms of MDD was analyzed. A prospective electronic survey (study 2) was emailed to longstanding and recently active members of the PatientsLikeMe MDD community. Study 1 analysis informed the objectives of the study 2 survey, which were to determine symptom perception and prioritization, cognitive symptoms of MDD, residual symptoms, and medication effectiveness.

RESULTS

In study 1 (N=17,166), cognitive symptoms were frequently reported, including "severe" difficulty in concentrating (28%). Difficulty in concentrating was reported even among patients with no/mild depression (80%) and those who considered their treatment successful (17%). In study 2 (N=2525), 23% (118/508) of patients cited cognitive symptoms as a treatment priority. Cognitive symptoms correlated with depression severity, including difficulty in making decisions, concentrating, and thinking clearly (rs=0.32, 0.36, and 0.34, respectively). Cognitive symptoms interfered with meaningful relationships and daily life tasks and had a profound impact on patients' ability to work and recover from depression.

CONCLUSIONS

Patients acknowledge that cognitive dysfunction in MDD limits their ability to recover fully and return to a normal level of social and occupational functioning. Further clinical understanding and characterization of MDD for symptom prioritization and relapse risk due to residual cognitive impairment are required to help patients return to normal cognitive function and aid their overall recovery.

What are they returning to? Psychosocial work environment as a predictor of returning to work among employees in treatment for common mental disorders: A prospective observational pre-post study

INTRODUCTION

Long-term sick leave and disabilities due to common mental disorders are challenging for society, employers, and individuals. Hence, we wanted to investigate whether psychosocial work environments experienced by employees undergoing treatment for such disorders was associated with return to work.

METHODS

At the start of treatment, 164 patients responded to questionnaires concerning their psychosocial work environment (the Job Demand-Control-Support model and the Effort-Reward Imbalance model), symptoms (The Clinical Outcomes in Routine Evaluation Outcome Measure) and ability to work (Work Ability Index). In addition, the respondents reported whether they were working or on sick leave at the start and end of their courses of treatment. Their therapists provided information about diagnoses.

RESULTS

Return to work was associated with control of decisions, support from colleagues, esteem, and job promotion opportunities as measured at the start of treatment. In multivariate analyses, control over decisions and job promotion opportunities continued to predict return to work when adjusted for symptoms, current work ability, and expected future work ability.

DISCUSSION

The working conditions that predicted return to work are considered to facilitate work performance and to be sources of motivation, job satisfaction, and job commitment. Consequently, it is important to examine whether this patient group has a favorable working environment and consider changes in the workplace if the environment is not favorable.

The association between having a coordinator and return to work: the rapid-return-to-work cohort study

OBJECTIVES

The aim of this study was to assess if the reported provision of a coordinator was associated with time to first return to work (RTW) and first full RTW among sick-listed employees who participated in different rapid-RTW programmes in Norway.

DESIGN

The study was designed as a cohort study.

SETTING

Rapid-RTW programmes financed by the regional health authority in hospitals and Norwegian Labour and Welfare Administration in Norway.

PARTICIPANTS

The sample included employees on full-time sick leave (n=326) who participated in rapid-RTW programmes (n=43), who provided information about the coordination of the services they received. The median age was 46 years (minimum-maximum 21-67) and 71% were female. The most common reported diagnoses were musculoskeletal (57%) and mental health disorders (14%).

INTERVENTIONS

The employees received different types of individually tailored RTW programmes all aimed at a rapid RTW; occupational rehabilitation (64%), treatment for medical or psychological issues, including assessment, and surgery (26%), and follow-up and work clarification services (10%). It was common to be provided with a coordinator (73%).

PRIMARY AND SECONDARY OUTCOME MEASURES

Outcomes were measured as time to first RTW (graded and 100%) and first full RTW (100%).

RESULTS

Employees provided with a coordinator returned to work later than employees who did not have a coordinator; a median (95% CI) of 128 (80 to 176) days vs 61 (43 to 79) days for first RTW, respectively. This difference did not remain statistically significant in the adjusted regression analysis. For full RTW, there was no statistically significant difference between employees provided with a coordinator versus those who were not.

CONCLUSIONS

The model of coordination, provided in the Norwegian rapid-RTW programmes was not associated with a more rapid RTW for sick-listed employees. Rethinking how RTW coordination should be organised could be wise in future programme development.

Influence of adjuvant omega-3-polyunsaturated fatty acids on depression, sleep, and emotion regulation among outpatients with major depressive disorders - Results from a double-blind, randomized and placebo-controlled clinical trial

BACKGROUND

Extant literature shows that adjuvant omega-3-polyunsaturated fatty acids (O3PUFAs) to a standard antidepressant medication impacts favorably on symptoms of depression in participants with major depressive disorders (MDD). The aim of the present study was to investigate, if and to what extent compared to placebo adjuvant O3PUFAs had a favorable impact on symptoms of depression, anxiety, sleep and emotion regulation among outpatients with MDD.

METHOD

A total of 50 outpatients (mean age: M = 42.46; 68% females) took part in this randomized, double-blind and placebo-controlled study. They were randomly assigned either to the O3PUFA- or to the placebo-condition. Standard medication was sertraline at therapeutic dosages. At baseline, six weeks and 12 weeks later at study completion participants completed questionnaires covering symptoms of depression, anxiety sensitivity, intolerance of uncertainty, sleep disturbances, and emotion regulation. In parallel, experts blind to participants' group assignment rated participants' depression with the Montgomery-Asberg Depression Scale.

RESULTS

Symptoms of depression (self- and experts' ratings) decreased over time, but more so in the O3PUFA condition, compared to the placebo condition. Likewise, anxiety sensitivity, intolerance of uncertainty and sleep disturbances improved, but again more so in the O3PUFA condition. Further, regulation and control of emotions and perception of other's emotions improved over time, but more so in the O3PUFA condition.

CONCLUSIONS

Among outpatients with MDD, and compared to placebo, adjuvant O3PUFAs to a standard medication improved not only symptoms of depression, but also dimensions of anxiety and sleep, and above all patients' competencies to regulate their emotions.

Psychological treatments for return to work in individuals on sickness absence due to common mental disorders or musculoskeletal disorders: a systematic review and meta-analysis of randomized-controlled trials

Purpose

Common mental disorders (CMDs) and musculoskeletal disorders are highly prevalent in the population and cause significant distress and disability, and high costs to society. The main objective of this systematic review and meta-analysis was to examine the outcome and comparative effectiveness of psychological interventions in reducing sickness absence (SA) due to CMDs or musculoskeletal disorders, compared to a waitlist control group, usual care or another clinical intervention.

Methods

We reviewed 3515 abstracts of randomized controlled trials published from 1998 to 2017. Of these, 30 studies were included in the analysis.

Results

The psychological interventions were overall more effective than treatment as usual in reducing SA (small effect sizes), but not compared to other clinical interventions. Results were similar for studies on CMDs and musculoskeletal pain. A few significant moderating effects were found for treatment-specific variables. However, these were  difficult to interpret as they pointed in different directions.

Conclusion

There was a small but significant effect of psychological treatments in reducing SA. We identified areas of improvement such as methodological problems among the included studies and failure to specifically address RTW in the interventions that were evaluated. Clinical implications of the findings, and ways of improving methodological rigour of future studies are discussed.

Multidisciplinary Intervention and Acceptance and Commitment Therapy for Return-to-Work and Increased Employability among Patients with Mental Illness and/or Chronic Pain: A Randomized Controlled Trial

Background: People on long-term sick leave often have a long-lasting process back to work, where the individuals may be in multiple and recurrent states; i.e., receiving different social security benefits or working, and over time they may shift between these states. The purpose of this study was to evaluate the effects of two vocational rehabilitation programs, compared to a control, on return-to-work (RTW) or increased employability in patients on long-term sick leave due to mental illness and/or chronic pain. Methods: In this randomized controlled study, 427 women and men were allocated to either (1) multidisciplinary team management, i.e., multidisciplinary assessments and individual rehabilitation management, (2) acceptance and commitment therapy (ACT), or (3) control. A positive outcome was defined as RTW or increased employability. The outcome was considered negative if the (part-time) wage was reduced or ceased, or if there was an indication of decreased employability. The outcome was measured one year after entry in the project and analyzed using binary and multinomial logistic regressions. Results: Participants in the multidisciplinary team group reported having RTW odds ratio (OR) 3.31 (95% CI 1.39–7.87) compared to the control group in adjusted models. Participants in the ACT group reported having increased employability OR 3.22 (95% CI 1.13–9.15) compared to the control group in adjusted models. Conclusions: This study of vocational rehabilitation in mainly female patients on long-term sick leave due to mental illness and/or chronic pain suggests that multidisciplinary team assessments and individually adapted rehabilitation interventions increased RTW and employability. Solely receiving the ACT intervention also increased employability.

Systematic review of interventions targeting sickness absence among pregnant women in healthcare settings and workplaces

OBJECTIVES

The high rate of sickness absence from work during pregnancy is recognised as a problem, and may be higher than necessary from a health perspective. The aim was to evaluate the effectiveness of interventions in healthcare settings and workplaces targeting sickness absence among pregnant women.

METHODS

Studies were eligible if they included pregnant women participating in any intervention in healthcare settings or workplaces. The outcome was length of sickness absence in days or number of episodes. Study design had to be either randomised controlled trials (RCTs) or quasi-experimental studies.The search for studies was conducted in PubMed, Scopus, CINAHL, PsycINFO, ClinicalTrials.gov and WHO trial registry. Risk of bias was assessed by the Joanna Briggs Institute standardised quality assessment instrument.

RESULTS

A total of nine studies were quality assessed and of these, four were excluded due to insufficient methodological quality. Five RCTs conducted in healthcare settings in Sweden and Norway were included. Due to heterogeneity, meta-analysis was not performed.Two RCTs examined complementary and alternative medicine and three RCTs the effect of physical exercise. In general, the frequency of women on sickness absence was lower in the intervention groups than the control groups, however, only among pregnant women who participated in a 12-week exercise programme, the frequency was significantly lower (22% vs 30%, p=0.04).

CONCLUSION

The evidence of interventions targeting sickness absence among pregnant women in healthcare settings is sparse, and no studies were conducted at workplaces.Future interventions including physical activity provided in collaboration with healthcare settings and workplaces are requested. Studies should measure sickness absence based on valid methods, measure compliance to the intervention and provide transparency of statistical methods.

[Development process of Evidence-based "Return-to-work Guidance in Occupational Health 2017"]

OBJECTIVE

"Return-to-work Guidance in Occupational Health 2017 (RTW Guidance 2017) " is the first occupational health guide in Japan that evaluates the quality of evidence and offers recommendations based on results of the systematic review of randomized controlled trials. Details of the systematic review of each review question (RQs) will be described separately. This article presents an overview of the method and process of developing the "RTW Guidance 2017."

MATERIALS AND METHODS

The guidance was developed following the previously-published "Method for developing evidence based occupational health guidance," which included the composition of a highly-transparent guidance developing group as well as the recruitment and selection of RQs. Using the Cochrane Library, PubMed, and Ichushi-Web, a literature search for the six RQs was conducted in January 2016 by partly modifying the search terms of the existing systematic review. Articles were selected according to the inclusion criteria, and the quality of evidence was evaluated using the GRADE approach. Meta-analysis was conducted for RQ2 and RQ4, and a qualitative systematic review was conducted for RQ5, RQ6, and cost-effectiveness. Recommendations were subsequently made after a thorough consideration for feasibility in Japan by examining the costs and available resources.

RESULTS

Based on a comprehensive literature search, eleven RQ2, four RQ4, one RQ5, and three RQ6 were selected. Support program for returning to work, such as "Re-work" for those who are temporarily not working due to musculoskeletal disorders or mental health disorder, was recommended based on moderate evidence (RQ2). For RQ4, the collaboration between occupational health practice and clinical practice was weakly recommended based on low evidence. For RQ5 that evaluated the usefulness of social support, intervention by the manager/co-worker was proposed as a "best practice statement" without indicating it as a recommendation. Work accommodation was weakly recommended based on low evidence in RQ6.

DISCUSSION AND CONCLUSION

From the result of systematic reviews, it was recommended for workers on sick leave more than four weeks regardless of sick leave and sickness absence that interventions during leave would improve work-related outcomes, such as earlier reinstatement. Although there is limited evidence regarding occupational health in Japan, it is important for many occupational health professionals to learn the method of developing guidance and to identify issues for future studies with priority in Japan.

Work and SCI: a pilot randomized controlled study of an online resource for job-seekers with spinal cord dysfunction

STUDY DESIGN

A prospective, parallel randomized controlled trial (RCT).

OBJECTIVES

To test the preliminary effects of an online resource targeted to job-seekers with spinal cord injury or disorder (SCI/D), and to determine the feasibility of proceeding to a full-scale RCT.

SETTING

A community cohort in Australia.

METHODS

Forty-eight adults (M = 42 years, SD = 10.95, 27 males) were randomized to receive 4-weeks access to the Work and SCI resource (n = 25) or to a wait-list control group (n = 23). The Work and SCI intervention involved six stand-alone learning modules which provided job-searching and career-planning information through text, videos, and interactive activities. Self-report measures were administered at baseline and after 4 weeks: Job Procurement Self-Efficacy Scale (JSES), Life Orientation Test-Revised (LOT-R), and Patient Health Questionnaire-9 (PHQ-9).

RESULTS

Online usage data identified high uptake of the Work and SCI resource, although study attrition was problematic. Intention-to-treat analyses failed to reach statistical significance, whereas complete data revealed a significant interaction effect for optimism (LOT-R).

CONCLUSION

Further research to develop and enhance Work and SCI is indicated. Remediable strategies to optimize recruitment and statistical power in a future definitive RCT are discussed.

Predictors of Return to Work 6 Months After the End of Treatment in Patients with Common Mental Disorders: A Cohort Study

Purpose Common mental disorders (CMDs) account for a large portion of sickness absence. Even after attending return to work (RTW) interventions, many patients with a CMD remain on sick leave. To identify people at risk of long-term work disability, more needs to be known about factors that predict RTW after treatment. Methods This was a prospective cohort study that followed 106 former patients at an RTW outpatient clinic for CMDs for 6 months after the end of treatment. Changes in work participation and mental health status between the end of treatment and the 6-month follow-up were analysed. Changes in work participation were used to identify patients with successful RTW. Patient characteristics and end-of-treatment measures of mental health status, work ability, generalized self-efficacy and expectations of future work ability, and changes in clinical outcome measures during treatment were included in logistic regression analyses to identify predictors of RTW at the 6-month follow-up. Results In the final model, high occupational status and higher work ability at the end of treatment predicted successful RTW at the 6-month follow-up. Further analyses showed that if the expectancy of future work ability improved or remained positive from before to the end of treatment, this was also strongly associated with RTW at the 6-month follow-up. Conclusions Among patients treated for CMDs, those with a low occupational status and who report lower work ability at the end of treatment are at risk of long-term disability.

Biopsychosocial predictors and trajectories of work participation after transdiagnostic occupational rehabilitation of participants with mental and somatic disorders: a cohort study

BACKGROUND

Group-based transdiagnostic occupational rehabilitation programs including participants with mental and somatic disorders have emerged in clinical practice. Knowledge is sparse on subsequent participation in competitive work. This study aimed to investigate trajectories for (re)entry to work for predefined subgroups in a diagnostically heterogeneous sample of sick-listed participants after completing occupational rehabilitation.

METHODS

A cohort of 212 participants aged 18-69 on long-term sick leave (> 8 weeks) with chronic pain, chronic fatigue and/or common mental disorders was followed for one year after completing a 3½-week rehabilitation intervention based on Acceptance and Commitment Therapy. Self-reported, clinical and registry data were used to study the associations between predefined biopsychosocial predictors and trajectories for (re)entry to competitive work (≥ 1 day per week on average over 8 weeks). Generalized estimating equations analysis was used to investigate trajectories.

RESULTS

For all biopsychosocial subgroups (re)entry to work increased over time. Baseline employment, partial sick leave and higher expectation of return to work (RTW) predicted higher probability of having (re)entered work at any given time after discharge. The odds of increasing reentry over time (statistical interaction with time) was weaker for the group receiving the benefit work assessment allowance compared with those receiving sickness benefit (OR = 0.92, p = 0.048) or for those on partial sick leave compared with full sick leave (OR 0.77, p < 0.001), but higher for those who at baseline had reported having a poor economy versus not (OR 1.16, p = 0.010) or reduced emotional functioning compared with not (OR 1.11, p = 0.012). Health factors did not differentiate substantially between trajectories.

CONCLUSIONS

Work participation after completing a transdiagnostic occupational rehabilitation intervention was investigated. Individual and system factors related to work differentiated trajectories for (re)entry to work, while individual health factors did not. Having a mental disorder did not indicate a worse prognosis for (re)entry to work following the intervention. Future trials within occupational rehabilitation are recommended to pivot their focus to work-related factors, and to lesser extent target diagnostic group.

Increasing return-to-work among people on sick leave due to common mental disorders: design of a cluster-randomized controlled trial of a problem-solving intervention versus care-as-usual conducted in the Swedish primary health care system (PROSA)

BACKGROUND

Common mental disorders affect about one-third of the European working-age population and are one of the leading causes of sick leave in Sweden and other OECD countries. Besides the individual suffering, the costs for society are high. This paper describes the design of a study to evaluate a work-related, problem-solving intervention provided at primary health care centers for employees on sick leave due to common mental disorders.

METHODS

The study has a two-armed cluster randomized design in which the participating rehabilitation coordinators are randomized into delivering the intervention or providing care-as-usual. Employees on sick leave due to common mental disorders will be recruited by an independent research assistant. The intervention aims to improve the employee's return-to-work process by identifying problems perceived as hindering return-to-work and finding solutions. The rehabilitation coordinator facilitates a participatory approach, in which the employee and the employer together identify obstacles and solutions in relation to the work situation. The primary outcome is total number of sick leave days during the 18-month follow-up after inclusion. A long-term follow-up at 36 months is planned. Secondary outcomes are short-term sick leave (min. 2 weeks and max. 12 weeks), psychological symptoms, work ability, presenteeism and health related quality of life assessed at baseline, 6 and 12-month follow-up. Intervention fidelity, reach, dose delivered and dose received will be examined in a process evaluation. An economic evaluation will put health-related quality of life and sick leave in relation to costs from the perspectives of society and health care services. A parallel ethical evaluation will focus on the interventions consequences for patient autonomy, privacy, equality, fairness and professional ethos and integrity.

DISCUSSION

The study is a pragmatic trial which will include analyses of the intervention's effectiveness, and a process evaluation in primary health care settings. Methodological strengths and challenges are discussed, such as the risk of selection bias, contamination and detection bias. If the intervention shows promising results for return-to-work, the prospects are good for implementing the intervention in routine primary health care.

Involving the employer to enhance return to work among patients with stress-related mental disorders - study protocol of a cluster randomized controlled trial in Swedish primary health care

BACKGROUND

Work-related stress has become a major challenge for social security and health care systems, employers and employees across Europe. In Sweden, sickness absence particularly due to stress-related disorders has increased excessively in recent years, and the issue of how to improve sustainable return to work in affected employees is high up on the political agenda. The literature on interventions for return to work in patients with common mental disorders is still inconclusive. This randomized controlled trial (RCT) aims to contribute with knowledge about how physicians and rehabilitation coordinators in primary health care can involve the employer in the rehabilitation of patients with stress-related disorders. The objective is to evaluate whether the early involvement of the patient's employer can reduce the time for return to work compared to treatment as usual. A process study will complete the RCT with information about what prerequisites primary health caregivers need to succeed with this endeavor.

METHODS

Twenty-two primary care centers were randomized to either intervention or control group. At the intervention centers, physicians and rehabilitation coordinators underwent training, providing them with both knowledge and practical tools to involve the employer in rehabilitation. At the patient level, employed patients with an ICD-10 F43 diagnosis were eligible for participation (n=132). Difference in proportion of patients on full- or part-time sick leave at three, six and 12 months after inclusion will be investigated. Register data, logbooks and interviews with coordinators and physicians at both intervention and control centers will be used for process evaluation.

DISCUSSION

Although the issue of how to tackle work-related stress can be recognized all across Europe, Sweden face an urgent need to curb the disproportional increase of stress-related disorders in the sick-leave statistics. Since physicians are limited by time constraints, the rehabilitation coordinator may be a helpful resource to take this contact. The current study will contribute to knowledge about how this collaboration can be organized to facilitate employer involvement and reduce time to return to work among patients suffering from work related stress.

Systematic review and meta-analysis of interventions aimed at enhancing return to work for sick-listed workers with common mental disorders, stress-related disorders, somatoform disorders and personality disorders

Objectives

Mental disorders are associated with significant functional impairment, sickness absence and disability. The consequences of sickness absence warrant investigation into interventions aimed at enhancing return to work (RTW) for workers with mental disorders. The present systematic review and meta-analysis aim to synthesise evidence on the effectiveness of interventions aimed at enhancing RTW in sick-listed workers with mental disorders.

Methods

EconLit, Embase, PsychInfo, PubMed, Svemed+ and Web of Science were searched for peer-reviewed, randomised or controlled studies assessing employment-related outcomes of interventions. A meta-analysis was conducted and meta-regressions were performed to explore prespecified potential sources of heterogeneity between studies.

Results

The literature search yielded 3777 publications of which 42 (n=38 938) were included in the systematic review and 32 (n=9459) had appropriate data for the meta-analysis. The pooled effect size (95 % CI) was 0.14 (0.07 to 0.22). Meta-regressions revealed that the heterogeneity could not be attributed to study quality, timing of the intervention or length of the intervention. However, it could be partly explained by number of components included in the intervention, if the intervention included contact to the work place and by the disorder targeted by the intervention.

Conclusions

The results reveal strong evidence for interventions including contact to the work place and multicomponent interventions and moderate evidence for interventions including graded RTW. In addition, the results provide strong evidence for interventions targeting stress compared with interventions targeting other mental disorders. The findings point to important implications for policy and design of future interventions.

Motivational interviewing in long-term sickness absence: study protocol of a randomized controlled trial followed by qualitative and economic studies

BACKGROUND

Motivational interviewing (MI), mainly used and shown effective in health care (substance abuse, smoking cessation, increasing exercise and other life style changes), is a collaborative conversation (style) about change that could be useful for individuals having problems related to return to work (RTW). The aim of this paper is to describe the design of a randomized controlled trial evaluating the effect of MI on RTW among sick listed persons compared to usual care, in a social security setting.

METHODS

The study is a randomized controlled trial with parallel group design. Individuals between 18 and 60 years who have been sick listed for more than 7 weeks, with a current sick leave status of 50-100%, are identified in the Norwegian National Social Security System and invited to participate in the study. Exclusion criteria are no employment and pregnancy. Included participants are randomly assigned to the MI intervention or one of two control groups. The MI intervention consists of two MI sessions offered by caseworkers at the Norwegian Labor and Welfare Service (NAV), while the comparative arms consist of a usual care group and a group that receives two extra sessions without MI content (to control for attentional bias). The primary outcome measure is the total number of sickness absence days during 12 months after inclusion, obtained from national registers. Secondary outcomes include time until full sustainable return to work, health-related quality of life and mental health status. In addition, a health economic evaluation, a feasibility/process evaluation and qualitative studies will be performed as part of the study.

DISCUSSION

A previous study has suggested an effect of MI on RTW for sick listed workers with musculoskeletal complaints. The present study will evaluate the effect of MI for all sick listed workers, regardless of diagnosis. The knowledge from this study will potentially be important for policy makers, clinicians and other professionals` practical work.

Effects on work ability, job strain and quality of life of monitoring depression using a self-assessment instrument in recurrent general practitioner consultations: A randomized controlled study

BACKGROUND:

Depression reduces individuals’ function and work ability and is associated with both frequent and long-term sickness absence.

OBJECTIVE:

Investigate if monitoring of depression course using a self-assessment instrument in recurrent general practitioner (GP) consultations leads to improved work ability, decreased job strain, and quality of life among primary care patients.

METHODS:

Primary care patients n = 183, who worked. In addition to regular treatment (control group), intervention patients received evaluation and monitoring and used the MADRS-S depression scale during GP visit at baseline and at visits 4, 8, and 12 weeks. Work ability, quality of life and job strain were outcome measures.

RESULTS:

Depression symptoms decreased in all patients. Significantly steeper increase of WAI at 3 months in the intervention group. Social support was perceived high in a significantly higher frequency in intervention group compared to control group.

CONCLUSIONS:

Monitoring of depression course using a self-assessment instrument in recurrent GP consultations seems to lead to improved self-assessed work ability and increased high social support, but not to reduced job strain or increased quality of life compared to TAU. Future studies concerning rehabilitative efforts that seek to influence work ability probably also should include more active interventions at the workplace.

Effectiveness of Graded Return to Work After Multimodal Rehabilitation in Patients with Mental Disorders: A Propensity Score Analysis

Purpose Graded return to work (GRTW) is a strategy aimed at bringing people gradually back to coping with a full workload after an extended period of sick leave. This study aims to determine the effect of GRTW in addition to a multimodal rehabilitation on longer-term work participation in people with chronic mental disorders (CMDs). Methods Patients filled out questionnaires at the start of a multimodal rehabilitation and 15 months later. Balanced groups (GRTW, no GRTW) were formed by propensity score matching based on 27 covariates. The primary outcome measures were the return to work (RTW) status at follow-up and the number of days on sick leave during follow-up. Results From 1062 data sets (GRTW 508, no GRTW 554), 381 pairs were matched (age: 47.8 years; 78% female; 65% affective disorders, 28% neurotic or somatic disorders). At follow-up, 88% of the GRTW group had returned to work compared to only 73% of the controls (RR = 1.22, 1.13-1.31). The mean sick leave duration during the follow-up period was 7.0 weeks in the GRTW group compared to 13.4 weeks in the control group (p < 0.001). Additional explorative analyses showed that these effects were only observed in patients with an unsure or negative subjective RTW prognosis. Conclusions Based on this analysis, GRTW in addition to a multimodal rehabilitation is effective in enhancing successful work participation in people with CMDs. Earlier studies showing larger effects in people with a higher risk of a non-RTW were confirmed.

Effectiveness of Workplace Interventions in Return-to-Work for Musculoskeletal, Pain-Related and Mental Health Conditions: An Update of the Evidence and Messages for Practitioners

Purpose The objective of this systematic review was to synthesize evidence on the effectiveness of workplace-based return-to-work (RTW) interventions and work disability management (DM) interventions that assist workers with musculoskeletal (MSK) and pain-related conditions and mental health (MH) conditions with RTW. Methods We followed a systematic review process developed by the Institute for Work & Health and an adapted best evidence synthesis that ranked evidence as strong, moderate, limited, or insufficient. Results Seven electronic databases were searched from January 1990 until April 2015, yielding 8898 non-duplicate references. Evidence from 36 medium and high quality studies were synthesized on 12 different intervention categories across three broad domains: health-focused, service coordination, and work modification interventions. There was strong evidence that duration away from work from both MSK or pain-related conditions and MH conditions were significantly reduced by multi-domain interventions encompassing at least two of the three domains. There was moderate evidence that these multi-domain interventions had a positive impact on cost outcomes. There was strong evidence that cognitive behavioural therapy interventions that do not also include workplace modifications or service coordination components are not effective in helping workers with MH conditions in RTW. Evidence for the effectiveness of other single-domain interventions was mixed, with some studies reporting positive effects and others reporting no effects on lost time and work functioning. Conclusions While there is substantial research literature focused on RTW, there are only a small number of quality workplace-based RTW intervention studies that involve workers with MSK or pain-related conditions and MH conditions. We recommend implementing multi-domain interventions (i.e. with healthcare provision, service coordination, and work accommodation components) to help reduce lost time for MSK or pain-related conditions and MH conditions. Practitioners should also consider implementing these programs to help improve work functioning and reduce costs associated with work disability.

Clinical effectiveness of care managers in collaborative care for patients with depression in Swedish primary health care: a pragmatic cluster randomized controlled trial

Background

Depression is one of the leading causes of disability and affects 10-15% of the population. The majority of people with depressive symptoms seek care and are treated in primary care. Evidence internationally for high quality care supports collaborative care with a care manager. Our aim was to study clinical effectiveness of a care manager intervention in management of primary care patients with depression in Sweden.

Methods

In a pragmatic cluster randomized controlled trial 23 primary care centers (PCCs), urban and rural, included patients aged ≥ 18 years with a new (< 1 month) depression diagnosis. Intervention consisted of Care management including continuous contact between care manager and patient, a structured management plan, and behavioral activation, altogether around 6-7 contacts over 12 weeks. Control condition was care as usual (CAU). Outcome measures: Depression symptoms (measured by Mongomery-Asberg depression score-self (MADRS-S) and BDI-II), quality of life (QoL) (EQ-5D), return to work and sick leave, service satisfaction, and antidepressant medication. Data were analyzed with the intention-to-treat principle.

Results

One hundred ninety two patients with depression at PCCs with care managers were allocated to the intervention group, and 184 patients at control PCCs were allocated to the control group. Mean depression score measured by MADRS-S was 2.17 lower in the intervention vs. the control group (95% CI [0.56; 3.79], p = 0.009) at 3 months and 2.27 lower (95% CI [0.59; 3.95], p = 0.008) at 6 months; corresponding BDI-II scores were 1.96 lower (95% CI [− 0.19; 4.11], p = 0.07) in the intervention vs. control group at 6 months. Remission was significantly higher in the intervention group at 6 months (61% vs. 47%, p = 0.006). QoL showed a steeper increase in the intervention group at 3 months (p = 0.01). During the first 3 months, return to work was significantly higher in the intervention vs. the control group. Patients in the intervention group were more consistently on antidepressant medication than patients in the control group.

Conclusions

Care managers for depression treatment have positive effects on depression course, return to work, remission frequency, antidepressant frequency, and quality of life compared to usual care and is valued by the patients.

Prevention of Common Mental Disorders in Employees. Perspectives on Collaboration from Three Health Care Professions

Collaboration among occupational health physicians, primary care physicians and psychotherapists in the prevention and treatment of common mental disorders in employees has been scarcely researched. To identify potential for improvement, these professions were surveyed in Baden-Württemberg (Germany). Four hundred and fifty occupational health physicians, 1000 primary care physicians and 700 resident medical and psychological psychotherapists received a standardized questionnaire about their experiences, attitudes and wishes regarding activities for primary, secondary and tertiary prevention of common mental disorders in employees. The response rate of the questionnaire was 30% (n = 133) among occupational health physicians, 14% (n = 136) among primary care physicians and 27% (n = 186) among psychotherapists. Forty percent of primary care physicians and 33% of psychotherapists had never had contact with an occupational health physician. Psychotherapists indicated more frequent contact with primary care physicians than vice versa (73% and 49%, respectively). Better cooperation and profession-specific training on mental disorders and better knowledge about work-related stress were endorsed. For potentially involved stakeholders, the importance of interdisciplinary collaboration for better prevention and care of employees with common mental disorders is very high. Nevertheless, there is only little collaboration in practice. To establish quality-assured cooperation structures in practice, participants need applicable frameworks on an organizational and legal level.

Efficacy of antidepressants on measures of workplace functioning in major depressive disorder: A systematic review

INTRODUCTION

Work-related disability and productivity loss in Major Depressive Disorder (MDD) are critical determinants of patient quality of life and contribute significantly to the human and economic costs of MDD. Notwithstanding the return to work and pre-morbid levels of functioning as a critical therapeutic objective among individuals with MDD, it is unclear whether antidepressant treatment significantly and reliably improves measures of workplace functioning. Herein, we investigate to what extent antidepressant treatment improves workplace functioning among adults with MDD.

METHODS

We conducted a systematic review of randomized, double-blind, placebo-controlled or active comparator clinical trials primarily or secondarily investigating the efficacy of antidepressant agents on subjective ratings of workplace functioning and/or measures of work absence.

RESULTS

Thirteen placebo-controlled and four active comparator clinical trials reported on the efficacy of agomelatine, bupropion, desvenlafaxine, duloxetine, fluoxetine, levomilnacipran, paroxetine, sertraline, venlafaxine, or vortioxetine on subjective measures of workplace impairment. Overall, antidepressant treatment improved standardized measures of workplace functioning (e.g., Sheehan Disability Scale-work item). One placebo-controlled trial of agomelatine and one clinical trial comparing the efficacy of vortioxetine to that of venlafaxine had mixed results on measures of work absence.

LIMITATIONS

Included interventional trials evaluated work-related disability as a secondary outcome using subjective rating scales.

CONCLUSION

Extant data suggest that antidepressant treatment improves workplace outcomes in MDD. The capability of antidepressants in improving measures of workplace functioning should be considered in cost-benefit analyses to better inform cost-modelling studies pertaining to antidepressant therapy.

Effects of internet-based cognitive behavioural therapy and physical exercise on sick leave and employment in primary care patients with depression: two subgroup analyses

OBJECTIVES

Depression can negatively impact work capacity, but treatment effects on sick leave and employment are unclear. This study evaluates if internet-based cognitive behavioural therapy (ICBT) or physical exercise (PE), with already reported positive effects on clinical outcome and short-term work ability, has better effects on employment, sick leave and long-term work ability compared with treatment as usual (TAU) for depressed primary care patients (German clinical trials: DRKS00008745).

METHODS

After randomisation and exclusion of patients not relevant for work-related analysis, patients were divided into two subgroups: initially unemployed (total n=118) evaluated on employment, and employed (total n=703) evaluated on long-term sick leave. Secondary outcomes were self-rated work ability and average number of sick days per month evaluated for both subgroups. Assessments (self-reports) were made at baseline and follow-up at 3 and 12 months.

RESULTS

For the initially unemployed subgroup, 52.6% were employed after 1 year (response rate 82%). Both PE (risk ratio (RR)=0.44; 95% CI 0.23 to 0.87) and ICBT (RR=0.37; 95% CI 0.16 to 0.84) showed lower rates compared with TAU after 3 months, but no difference was found after 1 year (PE: RR=0.97; 95% CI 0.69 to 1.57; ICBT: RR=1.23; 95% CI 0.72 to 2.13). For those with initial employment, long-term sick leave (response rate 75%) decreased from 7.8% to 6.5%, but neither PE (RR=1.4; 95% CI 0.52 to 3.74) nor ICBT (RR=0.99; 95% CI 0.39 to 2.46) decreased more than TAU, although a temporary positive effect for PE was found. All groups increased self-rated work ability with no differences found.

CONCLUSIONS

No long-term effects were found for the initially unemployed on employment status or for the initially employed on sick leave. New types of interventions need to be explored.

Integrated mental health care and vocational rehabilitation to improve return to work rates for people on sick leave because of depression and anxiety (the Danish IBBIS trial): study protocol for a randomized controlled trial

BACKGROUND

Depression and anxiety are among the largest contributors to the global burden of disease and have negative effects on both the individual and society. Depression and anxiety are very likely to influence the individual's work ability, and up to 40% of the people on sick leave in Denmark have depression and/or anxiety. There is no clear evidence that treatment alone will provide sufficient support for vocational recovery in this group. Integrated vocational and health care services have shown good effects on return to work in other, similar welfare contexts. The purpose of the IBBIS (Integrated Mental Health Care and Vocational Rehabilitation to Individuals on Sick Leave Due to Anxiety and Depression) interventions is to improve and hasten the process of return to employment for people in Denmark on sick leave because of depression and anxiety.

METHODS/DESIGN

This three-arm, parallel-group, randomized superiority trial has been set up to investigate the effectiveness of the IBBIS mental health care intervention and the integrated IBBIS mental health care and IBBIS vocational rehabilitation intervention for people on sick leave because of depression and/or anxiety in Denmark. The trial has an investigator-initiated multicenter design. A total of 603 patients will be recruited from Danish job centers in 4 municipalities and randomly assigned to one of 3 groups: (1) IBBIS mental health care integrated with IBBIS vocational rehabilitation, (2) IBBIS mental health care and standard vocational rehabilitation, and (3) standard mental health care and standard vocational rehabilitation. The primary outcome is register-based return to work at 12 months. The secondary outcome measures are self-assessed level of depression (Beck Depression Inventory II), anxiety (Beck Anxiety Inventory), stress symptoms (Four-Dimensional Symptom Questionnaire), work and social functioning (Work and Social Adjustment Scale), and register-based recurrent sickness absence.

DISCUSSION

This study will provide new knowledge on vocational recovery, integrated vocational and health care interventions, and prevention of recurrent sickness absence among people with depression and anxiety. If the effect on return to work is different in the intervention groups, this study can contribute to current knowledge on shared care models for health care and vocational rehabilitation services.

Les coûts des troubles mentaux en milieu de travail peuvent-ils être réduits ?

Le Forum économique mondial estime que, d’ici 2030, les coûts mondiaux des troubles mentaux devraient atteindre six mille milliards de dollars ; environ deux tiers de ces coûts seront attribués à la perte de productivité liée à l’incapacité. Cet article bref, examine les facteurs liés aux coûts de la maladie mentale en milieu de travail, identifie certains des éléments du milieu de travail qui pourraient être ciblés pour réduire les coûts et examine des exemples de types d’interventions en milieu de travail qui peuvent réduire les coûts.

Il existe au moins deux approches principales pour réduire les coûts relatifs aux troubles mentaux en milieu de travail. La première vise à réduire la prévalence des troubles mentaux chez les travailleurs ainsi que l’incidence des absences maladie. La seconde approche est de permettre un plus grand accès aux traitements requis. Ensemble, ces approches permettraient de réduire les coûts de façon significative, notamment en créant un climat de soutien et de solidarité dans les milieux de travail.

Return-to-work intervention versus usual care for sick-listed employees: health-economic investment appraisal alongside a cluster randomised trial

OBJECTIVE

To evaluate the health-economic costs and benefits of a guided eHealth intervention (E-health module embedded in Collaborative Occupational healthcare (ECO)) encouraging sick-listed employees to a faster return to work.

DESIGN

A two-armed cluster randomised trial with occupational physicians (OPs) (n=62), clustered and randomised by region into an experimental and a control group, to conduct a health-economic investment appraisal. Online self-reported data were collected from employees at baseline, after 3, 6, 9 and 12 months.

SETTING

Occupational health care in the Netherlands.

PARTICIPANTS

Employees from small-sized and medium-sized companies (≥18 years), sick-listed between 4 and 26 weeks with (symptoms of) common mental disorders visiting their OP.

INTERVENTIONS

In the intervention group, employees (N=131) received an eHealth module aimed at changing cognitions regarding return to work, while OPs were supported by a decision aid for treatment and referral options. Employees in the control condition (N=89) received usual sickness guidance.

OUTCOMES MEASURES

Net benefits and return on investment based on absenteeism, presenteeism, health care use and quality-adjusted life years (QALYs) gained.

RESULTS

From the employer's perspective, the incremental net benefits were €3187 per employee over a single year, representing a return of investment of €11 per invested Euro, with a break-even point at 6 months. The economic case was also favourable from the employee's perspective, partly because of QALY health gains. The intervention was costing €234 per employee from a health service financier's perspective. The incremental net benefits from a social perspective were €4210. This amount dropped to €3559 in the sensitivity analysis trimming the 5% highest costs.

CONCLUSIONS

The data suggest that the ECO intervention offers good value for money for virtually all stakeholders involved, because initial investments were more than recouped within a single year. The sometimes wide 95% CIs suggest that the costs and benefits are not always very precise estimates and real benefits could vary considerably.

Fostering needs assessment and access to medical rehabilitation for patients with chronic disease and endangered work ability: protocol of a multilevel evaluation on the effectiveness and efficacy of a CME intervention for general practitioners

BACKGROUND

Studies show that endangered work ability (EWA) can be maintained or restored through medical rehabilitation (MR). For patients, general practitioners (GP) represent an important point of access to MR in outpatient care. However, many different barriers and shortcomings hinder GPs in both timely detection of the need for MR and the recognition of its potentials for their EWA-patients. These are necessary if GPs are to adequately inform patients about MR options and successfully support applications for MR. This study describes the evaluation of a continuing medical education (CME) module designed to improve rehabilitation-related practical performance of GPs regarding a) subjective satisfaction of GPs with the CME module, b) stability of attitudes and knowledge over time regarding rehabilitation, and c) subjective and objective changes in MR-related competencies needed to support MR applications.

METHODS

This study is an open, non-randomised, pre-post-intervention study. The intervention involves a CME module for GPs (n = 1365) in the German state of Saxony-Anhalt on the topic of medical rehabilitation in connection with the federal German pension fund (Deutsche Rentenversicherung). The module will be initially held as regularly scheduled meetings in moderated GP quality circles (QC), and then offered as a written self-study unit. At the end it will be evaluated by the GPs. The study's primary focus is on the organizational practice as measured by the number of approved MR applications supported by medical reports submitted by the participating GPs in the 6 months before and 6 months after the CME module. Other study aims involve measuring self-perceived competencies of GPs, as well as their attitudes towards and knowledge of rehabilitation (both upon completing the CME and 6 months later). In addition, the level of satisfaction with the CME module will be analysed among participating GPs and QC moderators (as CME facilitators).

DISCUSSION

Implementing targeted CME on complex topics such as those involving barriers is possible, even promising, when using QCs and their moderators. Of particular importance is how aware moderating physicians are of the relevance of MR need detection and access.

ETHICS AND DISSEMINATION

The ethics committee of the Martin-Luther-Universität Halle-Wittenberg has registered this study under the number 2014-13. The study will be reported on in peer-reviewed journals and at national and international conferences. The results will be available to current and future initiatives aiming to improve detection of MR need and making MR accessible to EWEC patients needing such support to minimize the effects of chronic disease on their livess.

The issue of "long-term" fit notes for depression in the UK: patient, GP and general practice variation

Background: Depression is an important cause of certified sickness absence in the UK. It is not known what factors are associated with variation in length of sickness certificates issued by the GP to the depressed patient.Aims: The purpose of the study was to identify patient, GP and practice factors associated with the issue of a long-term (> 4 week) fit note for depression.Methods: Sixty-eight UK general practices collected sickness certification data for 12 months.Results: Over 35% of 8127 fit notes issued to 3361 patients for depression were classed as long-term (over four weeks in duration). Having previous fit notes for depression, not having "may be fit" advice on the fit note, older patient age, the patient living in a deprived neighbourhood and a higher practice deprivation status were all significant predictors of a long-term fit note. Depression fit notes issued by female GPs to female patients were less likely to be long-term. Other GP factors were not significant predictors of a long-term depression note.Conclusions: Reducing the number of long-term sickness certificates issued to people with depression should be considered part of return-to work and job retention strategies.

Internet- and mobile-based aftercare and follow-up for mental disorders: protocol of a systematic review and meta-analysis

INTRODUCTION

Mental disorders are characterised by a high likelihood of symptom recurrence or chronicity. Thus, in the vulnerable post-discharge phase, aftercare and follow-up aim at stabilising treatment effects, promoting functionality and preventing relapse or readmission. Internet- and mobile-based interventions may represent low threshold and effective extensions to aftercare in tertiary prevention of mental disorders.

OBJECTIVES

The planned systematic review and meta-analysis aims to synthesise and analyse existing evidence on the effectiveness of psychological internet- and mobile-based aftercare or follow-up in maintaining treatment effects and/or preventing recurrence in adults with mental disorders.

METHODS AND ANALYSIS

Electronic databases (PsycInfo, MEDLINE and Cochrane Central Register of Controlled trials) will be searched systematically, complemented by a hand-search of ongoing trials and reference lists of selected studies. Data extraction and evaluation will be conducted by two independent researchersand quality will be assessed with the Cochrane risk of bias tool. Eligibility criteria for selecting studies will be: randomised controlled trials of internet-based and mobile-based, psychological aftercare and follow-up for the tertiary prevention of mental disorders in an adult population. Primary outcome will be symptom severity. Secondary outcomes will be symptom or disorder recurrence rate, rehospitalisation rate, functionality, quality of life or adherence to primary treatment. Further data items to be extracted will be: study design, intervention and technical characteristics, type of mental disorder or clinical symptom to be treated, target population items, setting, treatment engagement and assessment of additional outcome variables. Meta-analytic pooling will be conducted when data of included studies are comparable in terms of study design, intervention type, endpoints, assessments and target mental disorder. Cumulative evidence will be evaluated according to the Grading of Recommendations Assessment, Development and Evaluation framework.

ETHICS AND DISSEMINATION

Ethics approval is not required. Results from this review will be published in peer-reviewed journals and presented at international conferences.

Long-term effects of Internet-delivered cognitive behavioral therapy for depression in primary care - the PRIM-NET controlled trial

OBJECTIVE

Internet-delivered cognitive behavioral therapy (ICBT) is recommended as an efficient treatment alternative for depression in primary care. However, only few previous studies have been conducted at primary care centers (PCCs). We evaluated long-term effects of ICBT treatment for depression compared to treatment as usual (TAU) in primary care settings.

DESIGN

Randomized controlled trial.

SETTING

Patients were enrolled at16 PCCs in south-west Sweden.

PARTICIPANTS

Patients attending PCCs and diagnosed with depression (n = 90).

INTERVENTIONS

Patients were assessed by a primary care psychologist/psychotherapist and randomized to ICBT or TAU. The ICBT included an ICBT program consisting of seven modules and weekly therapist e-mail or telephone support during the 3-month treatment period.

MAIN OUTCOME MEASURES

Questionnaires on depressive symptoms (BDI-II), quality of life (EQ-5D) and psychological distress (GHQ-12) were administered at baseline, with follow-ups at 3, 6 and 12 months. Antidepressants and sedatives use, sick leave and PCC contacts were registered.

RESULTS

Intra-individual change in depressive symptoms did not differ between the ICBT group and the TAU group during the treatment period or across the follow-up periods. At 3-month follow-up, significantly fewer patients in ICBT were on antidepressants. However, the difference leveled out at later follow-ups. There were no differences between the groups concerning psychological distress, sick leave or quality of life, except for a larger improvement in quality of life in the TAU group during the 0- to 6-month period.

CONCLUSIONS

ICBT with weekly minimal therapist support in primary care can be equally effective as TAU among depressed patients also over a 12-month period.

Preventing sickness absenteeism among employees with common mental disorders or stress-related symptoms at work: Design of a cluster randomized controlled trial of a problem-solving based intervention versus care-as-usual conducted at the Occupational Health Services

BACKGROUND

Common mental disorders (CMDs) are among the leading causes of sick leave in Sweden and other OECD countries. They result in suffering for the individual and considerable financial costs for the employer and for society at large. The occupational health service (OHS) can offer interventions in which both the individual and the work situation are taken into account. The aim of this paper is to describe the design of a study evaluating the effectiveness of an intervention given at the OHS to employees with CMDs or stress-related symptoms at work. In addition, intervention fidelity and its relation to the outcome will be assessed in a process analysis.

METHODS

The study is designed as a cluster randomized trial in which the participating OHS consultants are randomized into either delivering the intervention or performing care as usual. Employees with CMDs or stress-related symptoms at work are recruited consecutively by the OHS consultants. The intervention aims to improve the match between the employee and the job situation. Interviews are held individually with the employee and the nearest supervisor, after which a joint meeting with both the employee and the supervisor takes place. A participatory approach is applied by which the supervisor and the employee are guided by the OHS consultant and encouraged to actively take part in problem solving concerning the work situation. Outcomes will be assessed at baseline and at six and 12 months. A long-term follow-up at 3 years will also be performed. The primary outcome is registered sickness absence during a 1-year period after study inclusion. Secondary outcomes are mental health and work ability. The intervention's cost effectiveness, compared to treatment as usual, both for society and for the employer will be evaluated. A process evaluation by both the OHS consultants and the employee will be carried out.

DISCUSSION

The study includes analyses of the effectiveness of the intervention (clinical and economic) as well as an analysis of its implementation at the participating OHSs. Possible methodological challenges such as selection bias and risk of contamination between OHS consultants delivering the experimental condition and consultants giving usual care are discussed.

Interventions to reduce the impact of unemployment and economic hardship on mental health in the general population: a systematic review

BACKGROUND

Job loss, debt and financial difficulties are associated with increased risk of mental illness and suicide in the general population. Interventions targeting people in debt or unemployed might help reduce these effects.

METHOD

We searched MEDLINE, Embase, The Cochrane Library, Web of Science, and PsycINFO (January 2016) for randomized controlled trials (RCTs) of interventions to reduce the effects of unemployment and debt on mental health in general population samples. We assessed papers for inclusion, extracted data and assessed risk of bias.

RESULTS

Eleven RCTs (n = 5303 participants) met the inclusion criteria. All recruited participants were unemployed. Five RCTs assessed 'job-club' interventions, two cognitive behaviour therapy (CBT) and a single RCT assessed each of emotional competency training, expressive writing, guided imagery and debt advice. All studies were at high risk of bias. 'Job club' interventions led to improvements in levels of depression up to 2 years post-intervention; effects were strongest among those at increased risk of depression (improvements of up to 0.2-0.3 s.d. in depression scores). There was mixed evidence for effectiveness of group CBT on symptoms of depression. An RCT of debt advice found no effect but had poor uptake. Single trials of three other interventions showed no evidence of benefit.

CONCLUSIONS

'Job-club' interventions may be effective in reducing depressive symptoms in unemployed people, particularly those at high risk of depression. Evidence for CBT-type interventions is mixed; further trials are needed. However the studies are old and at high risk of bias. Future intervention studies should follow CONSORT guidelines and address issues of poor uptake.

Return-to-work coordination programmes for improving return to work in workers on sick leave

BACKGROUND

To limit long-term sick leave and associated consequences, insurers, healthcare providers and employers provide programmes to facilitate disabled people's return to work. These programmes include a variety of coordinated and individualised interventions. Despite the increasing popularity of such programmes, their benefits remain uncertain. We conducted a systematic review to determine the long-term effectiveness of return-to-work coordination programmes compared to usual practice in workers at risk for long-term disability.

OBJECTIVES

To assess the effects of return-to-work coordination programmes versus usual practice for workers on sick leave or disability.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 11), MEDLINE, Embase, CINAHL and PsycINFO up to 1 November 2016.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) that enrolled workers absent from work for at least four weeks and randomly assigned them to return-to-work coordination programmes or usual practice.

DATA COLLECTION AND ANALYSIS

Two review authors independently screened titles, abstracts and full-text articles for study eligibility; extracted data; and assessed risk of bias from eligible trials. We contacted authors for additional data where required. We conducted random-effects meta-analyses and used the GRADE approach to rate the quality of the evidence.

MAIN RESULTS

We identified 14 studies from nine countries that enrolled 12,568 workers. Eleven studies focused on musculoskeletal problems, two on mental health and one on both. Most studies (11 of 14) followed workers 12 months or longer. Risk of bias was low in 10 and high in 4 studies, but findings were not sensitive to their exclusion.We found no benefits for return-to-work coordination programmes on return-to-work outcomes.For short-term follow-up of six months, we found no effect on time to return to work (hazard ratio (HR) 1.32, 95% confidence interval (CI) 0.93 to 1.88, low-quality evidence), cumulative sickness absence (mean difference (MD) -16.18 work days per year, 95% CI -32.42 to 0.06, moderate-quality evidence), the proportion of participants at work at end of the follow-up (risk ratio (RR) 1.06, 95% CI 0.86 to 1.30, low-quality evidence) or on the proportion of participants who had ever returned to work, that is, regardless of whether they had remained at work until last follow-up (RR 0.87, 95% CI 0.63 to 1.19, very low-quality evidence).For long-term follow-up of 12 months, we found no effect on time to return to work (HR 1.25, 95% CI 0.95 to 1.66, low-quality evidence), cumulative sickness absence (MD -14.84 work days per year, 95% CI -38.56 to 8.88, low-quality evidence), the proportion of participants at work at end of the follow-up (RR 1.06, 95% CI 0.99 to 1.15, low-quality evidence) or on the proportion of participants who had ever returned to work (RR 1.03, 95% CI 0.97 to 1.09, moderate-quality evidence).For very long-term follow-up of longer than 12 months, we found no effect on time to return to work (HR 0.93, 95% CI 0.74 to 1.17, low-quality evidence), cumulative sickness absence (MD 7.00 work days per year, 95% CI -15.17 to 29.17, moderate-quality evidence), the proportion of participants at work at end of the follow-up (RR 0.94, 95% CI 0.82 to 1.07, low-quality evidence) or on the proportion of participants who had ever returned to work (RR 0.95, 95% CI 0.88 to 1.02, low-quality evidence).We found only small benefits for return-to-work coordination programmes on patient-reported outcomes. All differences were below the minimal clinically important difference (MID).

AUTHORS' CONCLUSIONS

Offering return-to-work coordination programmes for workers on sick leave for at least four weeks results in no benefits when compared to usual practice. We found no significant differences for the outcomes time to return to work, cumulative sickness absence, the proportion of participants at work at end of the follow-up or the proportion of participants who had ever returned to work at short-term, long-term or very long-term follow-up. For patient-reported outcomes, we found only marginal effects below the MID. The quality of the evidence ranged from very low to moderate across all outcomes.
