Effectiveness of psychoeducation in reducing sickness absence and improving mental health in individuals at risk of having a mental disorder: a randomised controlled trial

Promoting labour market inclusion of the chronically ill: a scoping review of Scandinavian countries' efforts

OBJECTIVES

This article is a scoping review of efforts in labour market inclusion of the chronically ill in the Scandinavian countries, a research area that has received much political as well as research attention in recent years. The aim of the review was to identify promising strategies and the need for further research.

METHODS

Six electronic databases were searched for literature published between 2015 and 2020. We included peer-reviewed articles that studied the effect of measures, aimed at the workplace or at the individual, that are intended to increase participation. Our search resulted in 2718 articles; our screening procedures resulted in 47 included articles.

RESULTS

Among the included studies, musculoskeletal problems (17 articles) and mental health problems (29 articles) were the most frequent chronic conditions. Multimodal occupational rehabilitation programmes directed towards the individual employee were the most frequent interventions (30 articles). Return to work (24 articles) and sickness absence (12 articles) were the most common outcomes. About half (25 articles) of the included studies reported a positive impact of the intervention on work inclusion of the chronically ill.

CONCLUSIONS

Our review found little evidence of how government programmes directed towards the supply side of the labour market succeed in including the chronically ill. Our review further indicated that multidisciplinary workplace interventions have a substantial effect. We also identified a significant lack of research on the effect of various governmental policies and programmes, including local health, work and welfare services, and limited coordination and cooperation between health and work services professions.

Long-term follow-up study of work status among patients with work-related mental disorders referred to departments of occupational medicine in Denmark

OBJECTIVES

To describe the 5 year work status in patients referred for suspected work-related common mental disorders. To develop a prognostic model.

DESIGN

Register-based nationwide longitudinal follow-up study.

SETTING

All departments of occupational medicine in Denmark.

PARTICIPANTS

17 822 patients aged 18-67 years, seen for the first time at a Department of Occupational Medicine in Denmark from 2000 to 2013 and diagnosed with stress, depression, post-traumatic stress disorder, anxiety or other mental disorders.

INTERVENTIONS

All patients were seen for diagnostic assessment and causal evaluation of the work-relatedness of their disorders. Some departments offered patients with stress disorders psychological treatment, which, however, was not organised according to patient selection or type of treatment.

PRIMARY AND SECONDARY OUTCOME MEASURES

Register data were collected for 5 year periods before and after the patients' first assessment at a department. Weekly percentages of patients are presented according to work status. The outcome in the prognostic model was a high Work Participation Score (ie, working>75% of potential work weeks/year) at 5 year follow-up.

RESULTS

For all subgroups of patients, a high proportion were working (>75%) 1-5 years before assessment, and all experienced a large reduction in work status at time of assessment. At 1 year follow-up, almost 60% of patients with stress were working, whereas in the other patient subgroups, less than 40% were working. In the following years, practically no increase was observed in the percentage of patients working in any of the subgroups. Based on these 5 year follow-up data, we developed a work participation model with only moderate discrimination and calibration.

CONCLUSIONS

In Denmark, not all return to previous work status 5 years after a referral due to a suspected work-related common mental disorder. We developed a prognostic model with only moderate discrimination and calibration for long-term work participation after suggested work-related common mental disorders.

Effects of mindfulness-based stress reduction on psychological distress in health workers: A three-arm parallel randomized controlled trial

Mindfulness-based Stress Reduction (MBSR) has shown good efficacy for improving wellbeing in employees experiencing occupational stress. However, comparisons with other interventions, longer-term follow-up, and data from varying sociocultural contexts are lacking. This three-arm, parallel randomised controlled trial (RCT) examined the effects of MBSR on psychological distress in non-physician health workers in direct contact with patients. 105 participants were randomly allocated to either: (1) MBSR (N = 35), (2) Stress Management Course (SMC; N = 34) or (3) wait-list (N = 36). Participants and those assessing outcomes were blinded to group assignment. Participants completed questionnaires pre- and post-intervention and four months after the intervention. Psychological distress was measured using the General Health Questionnaire (GHQ-12) and Outcome Questionnaire (OQ-45). Secondary outcomes included perceived stress, job satisfaction, mindfulness skills and changes in salivary cortisol. 77 participants completed measures post-intervention and 52 at 4-month follow-up. MBSR showed a post-intervention effect in reducing GHQ-12 (ß = -0.80 [SE = 1.58] p < 0.01) and OQ-45 (ß = -0.72, [SE = 5.87] p < 0.05) psychological distress, compared to SMC and in reducing GHQ-12 (ß = -1.30 [SE = 1.38] p < 0.001) and OQ-45 (ß = -0.71, [SE = 5.58] p < 0.01) psychological distress compared to wait-list condition. In our secondary outcome, only MBSR was associated with a decrease in the cortisol awaking response by 23% (p < 0.05). At follow-up, only effects of MBSR on the psychological distress 'social role' subscale (ß = -0.76 [SE = 1.31] p < 0.05) remained significant, compared to SMC. In conclusion, MBSR appears useful in reducing short-term psychological distress in healthcare workers, but these effects were not maintained at follow-up. Trial registration: ISRCTN12039804.

Determining what constitutes an effective psychosocial 'return to work' intervention: a systematic review and narrative synthesis

PURPOSE

Work can offer a myriad of social and health benefits. Long-term sick leave can be detrimental to employers, individuals, families, and societies. The burden of long-term sick leave has motivated the development of return to work (RTW) interventions. This study sought to determine what constitutes an effective psychosocial RTW intervention, which included exploring whether the level of intervention intensity and intervention characteristics matter to RTW outcomes.

METHODS

A systematic review and narrative synthesis were undertaken. Studies were identified through six databases (Ovid Medline, CINAHL (EBSCOhost), PsycInfo (Ovid), ProQuest, Scopus, and Google Scholar) between 2011 and 3 September 2019. Randomised controlled trials (RCTs) or reviews published in English were eligible for inclusion if they targeted adults who were on sick leave/unemployed trying to return to full-capacity employment, had at least one structured psychosocial RTW intervention, and assessed RTW. Study quality was assessed using checklists from the Joanna Briggs Institute.

RESULTS

Database searching yielded 12,311 records. Eighteen RCTs (comprising 42 intervention/comparison groups), seven reviews (comprising 153 studies), and five grey literature documents were included. Included studies were of moderate-to-high quality. Research was primarily conducted in Europe and focused on psychological or musculoskeletal problems. RTW outcomes included RTW status, time until RTW, insurance claims, and sick days. Participating in a RTW program was superior to care-as-usual. RTW outcomes were similar between diverse interventions of low, moderate, and high intensity. Common foundational characteristics seen across effective RTW interventions included a focus on RTW, psychoeducation, and behavioural activation.

CONCLUSIONS

Evidence suggests that a low intensity approach to RTW interventions may be an appropriate first option before investment in high intensity, and arguably more expensive interventions, as the latter appear to provide limited additional benefit. More high-quality RCTs, from diverse countries, are needed to provide stronger evidence.

Mental health: Professional rehabilitation and the return to work - A systematic review

BACKGROUND

The problem of illnesses, sick leave and the necessary return to work and permanence at work has been determining the development of different protocols and professional rehabilitation programs in different countries.

OBJECTIVE

We sought to identify articles that address programs for professional rehabilitation and the return to work of people laid off due to mental health problems, and to verify the results of professional rehabilitation programs and the follow-up processes for such return.

METHOD

A systematic review was performed according to the criteria of the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA). The serial search of the articles was carried out in the electronic databases: Web of Science, MEDLINE/PubMed and Scopus. The variations in the descriptors served to find a greater range of significant results for the research.

RESULTS

In total, 2,306 articles were found. Another two articles that met the inclusion criteria were located through manual searches, adding up to a total of 2,308. Applying the exclusion criteria resulted in a final data set of 47 peer-reviewed articles.

CONCLUSIONS

The issues involving return to work and permanence in work were complex and multifaceted in the research articles studied. Recovery from Common Mental Disorders (CMDs) is a major cause of long-term sick leave and the granting of disability benefits. Many people with these diagnoses remain employed; however, further studies are needed with women, workers with fragile relationships, and immigrants.

An 8-week Stress Management Program in Information Technology Professionals and the Role of a New Cognitive Behavioral Method: a Pilot Randomized Controlled Trial

AIM

The aim of this study is to compare and evaluate the sort-term benefits of the effects of an 8-week stress management techniques in information technology professionals.

METHODS

In this parallel randomized controlled trial, participants were randomly assigned to either the stress management group (n=40; relaxation breathing, progressive muscle relaxation, guided imagery) or in the Pythagorean Self awareness group (n=41). Self-reported validated measures were used to evaluate perceived stress, health locus of control, anxiety and depression.

RESULTS

All groups were found with significantly better cognitive speed and verbal memory at the end of the follow-up. Taking into account the group by time interaction coefficients, PSAT was found significantly superior to standard SM with regards to depression, emotional intelligence, lifestyle and personal control and verbal memory suggesting that verbal memory improvement through time should be mostly attributed to PSAT. On the other hand, the cognitive speed improvement during follow-up should be attributed to both interventions.

CONCLUSIONS

These findings provide important insight into the role of stress management. Future studies should focus on randomized, controlled trials with larger samples and longer follow-up times.

Interventions on cognitions and perceptions that influence work participation of employees with chronic health problems: a scoping review

BACKGROUND

Cognitions and perceptions, such as motivation and return to work (RTW) expectations, can influence work participation of employees with chronic health problems. This makes these cognitions and perceptions important factors for occupational health professionals to intervene upon in order to increase work participation. There is, however, no overview of interventions that influence these factors and are aimed at increasing work participation. Therefore, the purpose of this scoping review is to explore available interventions that are focused on cognitions and perceptions of employees with chronic health problems and aimed at increasing work participation.

METHODS

A scoping review was carried out following the framework of Arksey and O'Malley. Ovid MEDLINE and PsycINFO were searched for original papers published between January 2013 and June 2020. We included studies that describe interventions that focus on at least one of ten cognitions and perceptions and on work participation. The risk of bias of the studies included was assessed using quality assessment tools from the Joanna Briggs Institute.

RESULTS

In total, 29 studies were identified that studied interventions aimed at changing at least one of ten cognitions and perceptions in order to change work participation. The interventions that were included mainly focused on changing recovery and RTW expectations, self-efficacy, feelings of control, perceived health, fear-avoidance beliefs, perceived work-relatedness of the health problem, coping strategies and catastrophizing. No interventions were found that focused on changing motivation or on optimism/pessimism. Four interventions were judged as effective in changing coping, self-efficacy, fear-avoidance beliefs, or perceived work-relatedness and work participation according to results of randomized controlled trials.

CONCLUSIONS

This review provides an overview of interventions that focus on changing cognitions and perceptions and work participation. Evidence was found for four effective interventions focused on changing these factors and increasing work participation. Occupational health professionals may use the overview of interventions to help employees with chronic health problems to increase their work participation.

The efficacy of cognitive behavioural therapy in somatoform disorders and medically unexplained physical symptoms: A meta-analysis of randomized controlled trials

BACKGROUND

This systematic review and meta-analysis aimed to update and give an overview of the evidence from published literature that focused on the efficacy of cognitive behaviour therapy (CBT) in the management of somatoform disorders and medically unexplained physical symptoms (MUPS).

METHODS

A comprehensive literature search was carried out through an electronic search of various databases on randomized controlled trials (RCTs). Primary outcome was the severity of somatic symptoms. Secondary outcomes were also measured based on severity of anxiety symptoms, severity of depressive symptoms, social functioning, physical functioning, doctor visits and the compliance with CBT, as well as follow-up visits. Effects were summarized by a random effects model using mean differences or odds ratio with 95% confidence intervals (CIs).

RESULTS

A total of 15 RCTs comprising 1671 patients with somatoform disorders or MUPS were enrolled in our systematic review and meta-analysis. The main analysis revealed that CBT could alleviate somatic symptoms: -1.31 (95% CI: -2.23 to -0.39, p = 0.005); anxiety symptoms: -1.89 (95% CI: -2.91 to -0.86; p < 0.001); depressive symptoms: -1.93 (95% CI: -3.56 to -0.31; p = 0.020); improve physical functioning: 4.19 (95% CI: 1.90 to 6.49; p < 0.001). The efficacy of CBT on alleviating somatic symptoms, anxiety and depressive symptoms were sustained on follow-up. CBT may not be effective in reducing the number of doctor visits: -1.23 (95% CI: -2.97 to 0.51; p = 0.166); and improving social functioning: 3.27 (95% CI: -0.08 to 6.63; p = 0.056). The results of subgroup analysis indicated that CBT was particularly beneficial when the duration of session was more than 50 min to reduce the severity of somatic symptoms from pre to post treatment time, when it was group based and applied affective and developed good interpersonal strategy during the treatment. Longer duration and frequency such as more than 10 sessions and 12 weeks treatments had significant effect on reduction of the comorbid symptoms including depression and anxiety, but they may underpin low level of compliance of CBT based treatments.

CONCLUSIONS

CBT is effective for the treatment of somatoform disorders and MUPS by reducing physical symptoms, psychological distress and disability.

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.

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.

Interventions for enhancing return to work in individuals with a common mental illness: systematic review and meta-analysis of randomized controlled trials

Common mental disorders (CMDs) are highly prevalent in the working population, and are associated with long-term sickness absence and disability. Workers on sick leave with CMDs would benefit from interventions that enable them to successfully return to work (RTW). However, the effectiveness of RTW interventions for workers with a CMD is not well studied. The objective of this review is to assess the effectiveness of existing workplace and clinical interventions that were aimed at enhancing RTW. A systematic review of studies of interventions for improving RTW in workers with a CMD was conducted. The main outcomes were proportion of RTW and sick-leave duration until RTW. Randomized controlled trials (RCTs) were identified from Medline/PubMed, PsycINFO, EMBASE, SocINDEX, and Human resource and management databases from January 1995 to 2016. Two authors independently selected studies, assessed risk of bias and extracted data. We pooled studies that we deemed sufficiently homogeneous in different comparison groups and assessed the overall quality of the evidence. We reviewed 2347 abstracts from which 136 full-text articles were reviewed and 16 RCTs were included in the analysis. Combined results from these studies suggested that the available interventions did not lead to improved RTW rates over the control group [pooled risk ratio 1.05, 95% confidence interval (CI) 0.97-1.12], but reduced the number of sick-leave days in the intervention group compared to the control group, with a mean difference of -13.38 days (95% CI -24.07 to -2.69).

Labour market trajectories following sickness absence due to self-reported all cause morbidity--a longitudinal study

BACKGROUND

To investigate differences in return to work (RTW) and employment trajectories in individuals on sick leave for either mental health reasons or other health related reasons.

METHODS

This study was based on 2036 new sickness absence cases who completed a questionnaire on social characteristics, expectations for RTW and reasons for sickness absence. They were divided into two exposure groups according to their self-reported sickness absence reason: mental health reasons or other health reasons. The outcome was employment status during the following 51 weeks and was measured both as time-to-event analysis and with sequence analysis.

RESULTS

Individuals with mental health reasons for sickness absence had a higher risk of not having returned to work (RR 0.87 (0.80;0.93)). Adjusting for gender, age, education and employment did not change the estimate, however, after adding RTW expectations to the model, the excess risk was no longer present (RR 1.01 (0.95;1.08)). In relation to the sequence analysis, individuals with mental health related absence had significantly higher odds of being in the sickness absence cluster and significantly lower odds for being in the fast RTW cluster, but when adjusting for RTW expectations, the odds were somewhat attenuated and no longer significant.

CONCLUSIONS

Employees on sick leave due to self-reported mental health problems spent more weeks in sickness absence and temporary benefits and had a higher risk of not having returned to work within a year compared to employees on sick leave due to other health reasons. The difference could be explained by their lower RTW expectations at baseline. This emphasises the need to develop suitable and specific interventions to facilitate RTW for this group of sickness absentees.
