Sickness absence: a systematic review and meta-analysis of psychological treatments for individuals on sick leave due to common mental disorders

Women's health and psychological well-being in the return-to-work process after long-term sick leave for common mental disorders: women's and first-line managers' perspectives

BACKGROUND AND AIM

Common mental disorders are common reasons for long-term sick leave, especially among women. Return to work is often complex and unsuccessful, why more knowledge is needed regarding women's health and psychological well-being in the return-to-work process. Therefore, the aim was to describe women's health and psychological well-being in the return-to-work process, from women's and first-line managers' perspectives.

METHODS

Individual interviews were conducted with 17 women and 16 first-line managers. Qualitative content analysis was performed based on the content areas "Women's health (i.e. overall well-being, both physical and psychological) throughout the whole RTW process" and "Women's psychological well-being (happiness, meaning and a sense of being significant) at work after work resumption" Themes and categories were created.

RESULTS

Women and managers had similar descriptions, i.e. that women's health and psychological well-being depend on the individual characteristics of women themselves, their private life, work and other stakeholders. However, women described relational work tasks (e.g. meeting patients) as beneficial for health, and highlighted small stressors in the work environment, which the managers did not. Having work that was compatible with private life, being in good health, having stimulating work tasks and strengthening relationships at work were important for the women's psychological well-being.

CONCLUSIONS

Based on women's and first-line managers experiences, promotion of women's health and psychological well-being during the return-to-work process requires individually adapted assessments and actions involving women's entire life situation. First-line managers should know that relational work tasks (e.g., meeting patients) can be beneficial for women's health as well as that minor stressor in the work environment can put their health at risk.

Trajectories of work disability among individuals with anxiety-, mood/affective-, or stress-related disorders in a primary healthcare setting

BACKGROUND

Anxiety-, mood/affective-, or stress-related disorders affect up to one-third of individuals during their lives and often impact their ability to work. This study aimed to delineate trajectories of work disability (WD) among individuals diagnosed with anxiety-, mood/affective-, or stress-related disorder in primary healthcare and to examine associations between trajectory group membership and sociodemographic, clinical, and clinical-related factors.

METHODS

The study population included working-age individuals, aged 22-62 years, living in Stockholm County, Sweden, who experienced a new episode of any anxiety-, mood/affective, or stress-related disorder in primary healthcare in 2017 (N = 11,304). Data were obtained from Swedish national and regional registers and were linked using pseudonymised unique personal identification numbers. The primary outcome was days with WD (sum of sickness absence and disability pension days) during the three years before and three years after a diagnosis of anxiety-, mood/affective-, or stress-related disorders in primary healthcare. A zero-inflated Poisson group-based trajectory model was used to identify groups of individuals with similar patterns of WD over the study period, with a multinomial logistic regression used to examine associations of sociodemographic, clinical, and clinical-related factors with trajectory group membership.

RESULTS

Four distinct trajectory groups were found, high increasing (5.1%), with high levels, from 16 to 80 days of WD in six-monthly intervals during follow-up, peak (11.1%), with a peak in WD, up to 32 days of WD, around the time of the diagnosis, low increasing (12.8%), with an increase in days of WD from 4 to 22 during the study period, and constant low (71.1%), with almost no WD over the study period. In multinomial regression models, diagnostic category, psychotropic medication use, a diagnosis of a psychiatric disorder within secondary healthcare, age at diagnosis, and occupation were associated with WD trajectory groups.

CONCLUSIONS

Around two-thirds of individuals treated for a new episode of any anxiety-, mood/affective-, or stress-related disorder in primary healthcare have an excellent prognosis regarding WD. Several sociodemographic and clinical characteristics were associated with group membership; these factors could identify individuals at risk of long-term welfare dependency and who might benefit from interventions to promote a return to work.

Cooperation in Return-to-work Interventions for Common Mental Disorders: An Ideal Theory Analysis of Actors, Goals, and Ethical Obstacles

The rise in the number of people on sick leave for common mental disorders is a growing concern, both from a societal and individual perspective. One common suggestion to improve the return-to-work process is increased cooperation between the relevant parties, including at least the employer, the social insurance agency and health care. This suggestion is often made on the presumption that all parties share the common goal of reintegrating the patient-employee back into the workplace. In this paper we investigate this presumption by mapping out the ethical frameworks of these three key actors in any return-to-work process. We show that although the goals of these actors often, and to a large extent, overlap there are potential differences and tensions between their respective goals. Further, we emphasise that there may be other limitations to an actor's participation in the process. In particular the health care system is required to respect patient autonomy and confidentiality. There is also an inherent tension in the dual roles of health care professionals as therapists and expert witnesses in work ability assessment. In conclusion, there are potential tensions between the key actors in the return-to-work process. These tensions need to be addressed in order to enable an increased cooperation between actors and to facilitate the development of a feasible plan of action for all parties, including the employee.

Effects of work-directed interventions on return-to-work in people on sick-leave for to common mental disorders-a systematic review

PURPOSE

To evaluate the body of evidence of the effects of work-directed interventions on return-to-work for people on sick leave due to common mental disorders (i.e., mild to moderate depression, anxiety, adjustment disorders and reactions to severe stress).

METHODS

The systematic review was conducted in accordance with an a priori developed and registered protocol (Prospero CRD42021235586). The certainty of evidence was assessed by two independent reviewers using the Grading of Recommendations, Assessment, Development and Evaluations.

RESULTS

We reviewed 14,794 records published between 2015 and 2021. Of these, eight RCTs published in eleven articles were included in the analysis.

POPULATION

Working age adults (18 to 64 years), on sick leave due to mild to moderate depression, anxiety, adjustment disorders or reactions to severe stress.

INTERVENTION

Work-directed interventions.

COMPARATOR

No comparator, Standard care, or other measures.

OUTCOME

return to work, number of days on sick leave, income. Overall, the effects of work-focused CBT and work-focused team-based support on RTW resulted in increased or faster return-to-work compared with standard care or no intervention (low certainty of evidence). The effects of Individual Placement and Support showed no difference in RTW compared with standard care (very low certainty of evidence).

CONCLUSION

Interventions involving the workplace could increase the probability of RTW. Areas in need of improvement in the included studies, for example methodological issues, are discussed. Further, suggestions are made for improving methodological rigor when conducting large scale trials.

Real-world outcome of rTMS treatment for depression within the Japanese public health insurance system: Registry data from Kansai TMS network

This study registered consecutive cases to elucidate the efficacy of rTMS treatment for depression within the Japanese public health insurance system. Of the 102 patients with depression who received rTMS over the left dorsolateral prefrontal cortex, 44 (43.1 %) patients reached remission and 14 (13.7 %) patients did not reach remission but responded to treatment. No serious adverse events occurred. Low baseline HAMD-17 score was associated with remission after rTMS treatment. Favorable outcomes of rTMS treatment were shown in this cohort within the Japanese public insurance system. Our results provide insights into rTMS treatment for depression in real-world clinical setting.

What is the volume, quality and characteristics of evidence relating to the effectiveness and cost-effectiveness of multi-disciplinary occupational health interventions aiming to improve work-related outcomes for employed adults? An evidence and gap map of systematic reviews

Background

In the UK, tens of millions of working days are lost due to work-related ill health every year, costing billions of pounds. The role of Occupational Health (OH) services is vital in helping workers to maintain employment when they encounter injury or illness. OH providers traditionally rely on a clinical workforce to deliver these services, particularly doctors and nurses with OH qualifications. However, the increasing demand for OH services is unlikely to be met in the future using this traditional model, due to the declining number of OH-trained doctors and nurses in the UK. Multi-disciplinary models of OH delivery, including a more varied range of healthcare and non-healthcare professionals, could provide a way to meet this new demand for OH services. There is a need to identify collaborative models of OH service delivery and review their effectiveness on return-to work outcomes. There is an existing pool of systematic review evidence evaluating workplace based, multi-disciplinary OH interventions, but it is difficult to identify which aspects of the content and/or delivery of these interventions may be associated with improved work-related outcomes.

Objectives

The aim of this evidence and gap map (EGM) was to provide an overview of the systematic review evidence that evaluates the effectiveness and cost-effectiveness of multi-disciplinary OH interventions intending to improve work-related outcomes.

Search Methods

In June 2021 we searched a selection of bibliographic databases and other academic literature resources covering a range of relevant disciplines, including health care and business studies, to identify systematic review evidence from a variety of sectors of employment. We also searched Google Search and a selection of topically relevant websites and consulted with stakeholders to identify reports already known to them. Searches were updated in February 2023.

Selection Criteria

Systematic reviews needed to be about adults (16 years or over) in employment, who have had absence from work for any medical reason. Interventions needed to be multi-disciplinary (including professionals from different backgrounds in clinical and non-clinical professions) and designed to support employees and employers to manage health conditions in the workplace and/or to help employees with health conditions retain and/or return to work following medical absence. Effectiveness needed to be measured in terms of return to work, work retention or measures of absence, or economic evaluation outcomes. These criteria were applied to the title and abstract and full text of each systematic review independently by two reviewers, with disagreements resolved through discussion. We awarded each systematic review a rating of 'High', 'Medium' or 'Low' relevance to indicate the extent to which the populations, interventions and their contexts synthesised within the review were consistent with our research question. We also recorded the number of primary studies included within each of the 'High' and 'Medium' reviews that were relevant to research question using the same screening process applied at review level.

Data Collection and Analysis

Summary data for each eligible review was extracted. The quality of the systematic reviews, rated as 'High' or 'Medium' relevance following full text screening, was appraised using the AMSTAR-2 quality appraisal tool. All data were extracted by one reviewer and checked by a second, with disagreements being settled through discussion. Summary data for all eligible systematic reviews were tabulated and described narratively. The data extracted from reviews of 'High' and 'Medium' relevance was imported into EPPI-Mapper software to create an EGM.

Stakeholder Involvement

We worked alongside commissioners and policy makers from the Department of Health and Social Care (DHSC) and Department of Work and Pensions (DWP), OH personnel, and people with lived experience of accessing OH services themselves and/or supporting employees to access OH services. Individuals contributed to decision making at all stages of the project. This ensured our EGM reflects the needs of individuals who will use it.

Main Results

We identified 98 systematic reviews that contained relevant interventions, which involved a variety of professionals and workplaces, and which measured effectiveness in terms of return to work (RTW). Of these, we focused on the 30 reviews where the population and intervention characteristics within the systematic reviews were considered to be of high or medium relevance to our research questions. The 30 reviews were of varying quality, split evenly between High/Moderate quality and Low/Critically-Low quality ratings. We did not identify any relevant systematic review evidence on any other work-related outcome of interest. Interventions were heterogenous, both within and across included systematic reviews. The EGM is structured according to the health condition experienced by participants, and the effectiveness of the interventions being evaluated, as reported within the included systematic reviews. It is possible to view (i) the quality and quantity of systematic review evidence for a given health condition, (ii) how review authors assessed the effectiveness or cost-effectiveness of the interventions evaluated. The EGM also details the primary studies relevant to our research aim included within each review.

Authors’ Conclusions

This EGM map highlights the array of systematic review evidence that exists in relation to the effectiveness or cost-effectiveness of multi-disciplinary, workplace-based OH interventions in supporting RTW. This evidence will allow policy makers and commissioners of services to determine which OH interventions may be most useful for supporting different population groups in different contexts. OH professionals may find the content of the EGM useful in identifying systematic review evidence to support their practice. The EGM also identifies where systematic review evidence in this area is lacking, or where existing evidence is of poor quality. These may represent areas where it may be particularly useful to conduct further systematic reviews.

Socioeconomic status, psychotherapy duration, and return to work from disability due to common mental disorders

Objective Low socioeconomic status (SES) is a risk factor for work disability due to common mental disorders (CMDs), one possible reason being inequal use of services. Psychotherapy is an evidence-based treatment for CMDs. This study examines socioeconomic and sociodemographic differences in psychotherapy attendance and an association of psychotherapy duration with return to work (RTW).Methods The study subjects (N = 12,263) were all Finnish citizens granted a disability pension (DP) due to CMDs in 2010-2012. Numbers of psychotherapy sessions (maximum 200) were collected from the nine-year interval around the DP grant. Socioeconomic and sociodemographic differences in psychotherapy duration (dependent variable) among DP recipients were studied using multinomial logistic regression models, likewise, the association between psychotherapy duration and RTW (dependent variable) among temporary DP recipients was examined.Results Higher SES, female gender, and younger age were positively associated with attending longer psychotherapies and surpassing the early treatment termination level (>10 sessions). Attending 11-60 psychotherapy sessions was positively associated with full RTW and partial RTW, whereas longer psychotherapies were not. Early termination was positively associated with partial RTW only.Conclusion This study demonstrates varying tendencies among CMD patients from different backgrounds to attend long rehabilitative psychotherapies, which may create inequalities in RTW.

Psychotherapy duration and work disability: A prospective Finnish register study

INTRODUCTION

The influence of psychotherapy duration on common mental disorder (CMD) outcomes remains a topic of ongoing debate. Whereas most research has focused on CMD symptom change, the evidence on the psychotherapy duration of subsequent CMD-related work disability and the change in psychotropic drug purchases is scarce.

METHODS

We used a register-based cohort representing 33% of the Finnish population. The participants included working-age individuals (N = 12,047, 76% women, mean age = 36) who initiated long-term psychotherapy, between 2014 and 2017. They were followed from 2011 to 2021 and psychotherapy duration ranged from less than a year to over 3 years. We used an interrupted time series design to analyze the psychotherapy duration-dependent changes in CMD-related work disability (primary outcome, operationalized as depression or anxiety-related sickness absence, SA, days) and the annual number of psychotropic drug purchases or distinct drugs purchased (secondary outcomes).

RESULTS

There were no differences in the levels of work disability or drug purchases before the psychotherapy. We observed a decreasing level and trend in all outcomes across all psychotherapy duration groups. The largest decline in level was observed in the <1-year duration group (88% decline for SA and 43%-44% for drug purchases) while the smallest decline was in the 3+ years duration group (73% for SA and 27% for drug purchases).

CONCLUSION

Work disability outcomes and duration varied among individuals, even with similar initial mental health-related work disability or use of auxiliary psychotropic treatments. Compared to longer psychotherapy, shorter psychotherapy was associated with sharper improvements.

Sick leave before, during, and after short-term outpatient psychotherapy: a cohort study on sick leave days and health care costs between behavioral and psychodynamic psychotherapies on anonymized claims data

BACKGROUND

Sick leave due to mental disorders poses a relevant societal and economic burden. Research on sick leave over a patient journey of individuals who received one of two treatment approaches - either behavioral (BT) or psychodynamic (PDT) psychotherapy - is scarce.

METHODS

We conducted a cohort study on anonymized German claims data for propensity-score matched patients who received short-term outpatient BT or PDT. We analyzed sick leave days and direct health care costs one year before, during, and one year after psychotherapy.

RESULTS

We analyzed data of patients who received BT and PDT, with N = 14 530 patients per group after matching. Patients showed sick leave days per person year of 33.66 and 35.05 days before, 35.99 and 39.74 days during, and 20.03 and 20.95 days after BT and PDT, respectively. Sick leave rates were overall higher in patients who received PDT. Both patient groups showed reductions of roughly 14 sick leave days per year, or 40%, from before to after therapy without a difference between BT and PDT (difference-in-difference [DiD] = -0.48, 95%-confidence interval [CI] -1.61 to 0.68). Same applies to direct health care costs which reduced in both groups by roughly 1800 EUR (DiD = 0, 95%-CI -158 to 157).

CONCLUSIONS

Results suggest similar reductions in sick leave days and direct health care costs from before to after BT and PDT. As sick leave is discussed to serve as an indicator of overall health and functioning in mental disorders, both treatments may have a similar positive impact on mental health.

Development, piloting and evaluation of an app-supported psychosocial prevention intervention to strengthen participation in working life: a study protocol of a mixed-methods approach

INTRODUCTION

Rates of incapacity to work due to mental disorders have increased in many European countries. The consequences of persistent stress can impact individuals' physical and psychological well-being and gradually develop into chronic stress. Mental disorders or symptoms of burn-out syndrome can have severe consequences. Mental disorders leading to work incapacity significantly burden the health system. Prevention interventions can protect against burn-out, depression, anxiety and other mental health disorders. Digital health is a promising approach to increase the utilisation of effective prevention interventions. This mixed-methods study evaluates a newly developed app-supported psychosocial prevention intervention called 'RV Fit Mental Health' to strengthen participation in working life.

METHODS AND ANALYSIS

The study uses a three-stage parallel mixed-methods design. This study accompanies the development (stage 1), piloting (stage 2) and evaluation (stage 3) of the new intervention. Within the stages, there is a quantitative as well as a qualitative research strand. Employed persons with an incipient mental disorder will be included. Additionally, experts within the project or connected areas will be included. Quantitative data will be analysed using multifactorial variance analyses in a pre-post design. Qualitative data will be analysed using qualitative content analysis. The study is a comprehensive research approach to investigate the development, piloting and evaluation of an app-supported psychosocial app-based prevention intervention. The rigour of the study will be achieved through data triangulation.

ETHICS AND DISSEMINATION

All participants will receive detailed study information and give written informed consent before data collection. Ethical approval was obtained from the Technical University of Munich Ethics Committee. All data collection will follow all legislative rules regarding data protection, also following the Declaration of Helsinki. The study results will be disseminated in peer-reviewed journals and presented at international conferences.

Changes in memory and attention during and after occupational rehabilitation: A longitudinal study

BACKGROUND

There is need for more knowledge about the relationship between work and cognitive functioning in sick-listed individuals.

OBJECTIVE

This study investigated whether the degree of work participation is relevant for recovery of cognitive functioning in sick-listed individuals.

METHODS

177 occupational rehabilitation participants and 70 controls participated in a non-randomised, longitudinal study. Participants completed computerised cognitive tests targeting sustained attention and working memory at start and end of rehabilitation and 3 and 12 months after rehabilitation. The change score performance in attention and memory between start and end, start and 3 months and 12 months was compared in individuals on sick leave 100-75%, 74-40% and 39-0% (three sick leave groups) of the time in the year after rehabilitation, and a control group not being on sick leave. Fixed effect analysis of covariance adjusting for education and work ability was used.

RESULTS

The sick leave group 100-75% had significantly lower score on work ability compared to the other groups at baseline. The main findings indicated that the sick leave group 39-0% improved significantly more in sustained attention compared to the sick leave group 100-75% between start and end of rehabilitation and from start of rehabilitation to 3 and 12 months after.

CONCLUSION

The degree of work participation seems relevant to recovery of the cognitive function sustained attention in sick-listed individuals. These findings encourage work rehabilitation clinicians, work consultants and employers to develop RTW plans which take into account that graded employment influence cognitive functioning.

Effectiveness of a person-centred eHealth intervention in reducing symptoms of burnout in patients with common mental disorders - secondary outcome analysis of a randomized controlled trial

BACKGROUND

The number of people with common mental disorders (CMDs), especially stress-related disorders, has increased in several countries, including Sweden, during the past decade. Patients seeking care for long-term stress report severe symptoms. Although person-centred care (PCC) has shown several benefits, studies evaluating the effects of a PCC eHealth intervention on patients with CMDs are scarce.

OBJECTIVE

The aim of this study was to compare levels of self-reported symptoms of burnout between a control group receiving treatment as usual (TAU) and an intervention group receiving TAU with the addition of a person-centred eHealth intervention, in patients on sick leave for CMDs.

METHODS

This study reports analysis of a secondary outcome measure from a randomized controlled trial. Patients (n = 209) on sick leave for CMDs were recruited from nine primary health care centres and allocated to either a control group (n = 107) or an intervention group (n = 102). The intervention consisted of phone support and an interactive digital platform built on PCC principles. Self-reported symptoms of burnout were assessed using the Shirom-Melamed Burnout Questionnaire (SMBQ) at baseline and at 3 and 6 months.

RESULTS

Our findings showed changes in SMBQ scores over time in both the control and the intervention group. There was no significant difference in SMBQ scores between the groups; however, a difference in change over time between the groups was observed. The SMBQ scores decreased significantly more in the intervention group than in the controls between 0 and 3 months and between 0 and 6 months. No differences in change between the two groups were seen between the 3- and 6-month follow-ups.

CONCLUSION

This person-centred eHealth intervention for patients on sick leave for CMDs showed a slight initial effect in reducing symptoms of burnout. Taking into account that both groups reported comparable SMBQ scores throughout the study period, the overall effect may be considered limited.

TRIAL REGISTRATION

The trial was registered in ClinicalTrials.gov (Identifier NCT03404583). Date of registration: 19/01/2018. https://clinicaltrials.gov/ct2/show/NCT03404583 .

Practical pathway for the management of depression in the workplace: a Canadian perspective

Major depressive disorder (MDD) and other mental health issues pose a substantial burden on the workforce. Approximately half a million Canadians will not be at work in any week because of a mental health disorder, and more than twice that number will work at a reduced level of productivity (presenteeism). Although it is important to determine whether work plays a role in a mental health condition, at initial presentation, patients should be diagnosed and treated per appropriate clinical guidelines. However, it is also important for patient care to determine the various causes or triggers including work-related factors. Clearly identifying the stressors associated with the mental health disorder can help clinicians to assess functional limitations, develop an appropriate care plan, and interact more effectively with worker's compensation and disability programs, as well as employers. There is currently no widely accepted tool to definitively identify MDD as work-related, but the presence of certain patient and work characteristics may help. This paper seeks to review the evidence specific to depression in the workplace, and provide practical tips to help clinicians to identify and treat work-related MDD, as well as navigate disability issues.

Evaluating the Effectiveness of Return-to-Work Interventions for Individuals with Work-Related Mental Health Conditions: A Systematic Review and Meta-Analysis

The workplace is a vital setting to support positive mental health. Mental health conditions in the workforce contribute to decreased work engagement and participation. There is existing literature on return-to-work (RTW) interventions for individuals with work-related mental health conditions, however, there lacks consensus on their effectiveness. Therefore, the primary aim of this systematic review was to synthesize the literature and evaluate the effectiveness of return-to-work interventions on return-to-work rates, quality of life, and psychological wellbeing for individuals with work-related mental health conditions. Selected articles were organized and identified using the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines and the Population/Intervention/Comparison/Outcome (PICO) framework. Quality assessment of the included studies was completed using the Critical Appraisal Skills Programme randomized controlled trials checklist and the Joanna Briggs Institute quasi-experimental studies checklist. A random effects meta-analysis model was performed using DerSimonian-Laird weighting to calculate standard mean difference and risk ratios to assess the impact of RTW interventions on return-to-work rates, absenteeism, stress symptoms, depression symptoms, and quality of life. A total of 28 out of 26,153 articles met the inclusion criteria. Diagnoses for participants in the studies ranged from work-related stress to work-related PTSD following exposure to a psychologically traumatizing event in the workplace. No significant differences were found for the meta-analyses examining return-to-work rates, absenteeism, depression, stress, and quality of life. The most effective interventions were found to be a multi-domain intervention (67% of participants RTW full time) and a health-focused intervention (85% RTW rate). Future research may consider establishing effective interventions to develop programs or policies supporting the RTW of employees and promote mental well-being among employees experiencing work-related mental health conditions.

Internet-delivered cognitive behavioral therapy (iCBT) for common mental disorders and subsequent sickness absence: a systematic review and meta-analysis

AIM

The study aimed to critically review and synthesize the best available evidence about the effectiveness of therapist-guided internet-delivered cognitive behavioral therapy (iCBT) in terms of reducing sickness absence (SA).

METHODS

We searched Medline (PubMed), Embase, PsycInfo, CINAHL, and Cochrane Central (up to November 2020) for English language peer-reviewed papers that described randomized controlled trials of therapist-guided iCBT compared with usual treatment for SA in adults with common mental disorders. Eligible studies were assessed with the Cochrane Risk of Bias 1 tool, meta-analysis was conducted using a random-effects model, and standardized mean differences (SMD) with 95% confidence intervals (CI) were reported. A subgroup analysis investigated potential moderating variables (diagnosis, SA at baseline, and estimated accuracy of self-report).

RESULTS

We identified 2788 references, of which 68 remained after the completion of the systematic screening process. A hand search of reference lists yielded no additional studies. The full texts of these 68 studies were appraised critically, and 11 were deemed to be suitable for a meta-analysis. SA was similar for iCBT and usual treatment groups (SMD: 0.02, 95% CI, -0.08 to 0.11), and remained similar even after the removal of two studies in which the recall time was over 3 months (SMD: 0.00, -0.11 to 0.12). Similar SA levels in intervention and control groups at 6-month and 12-month follow-up were observed in studies of participants with depression symptoms.

CONCLUSIONS

iCBT did not appear to be effective in terms of reducing (largely self-assessed) SA in adults with common mental disorders. There is a need to improve the method and consistency of assessing SA.

Interventions to reduce the risk of mental health problems in health and social care workplaces: A scoping review

Work in the health and social care sector is stressful, and work-related stress increases the risk of depression, anxiety, burnout, and sleep disorders. Although interventions to reduce stress and burnout at workplaces have been developed and studied, most studies have lacked the effectiveness to improve the situation. Thus, more knowledge on interventions and analysis of their mechanisms is needed to reduce the risk of more adverse mental health problems (MHP). We conducted a scoping review to identify the relevant literature on individual and organizational interventions to improve mental health in health and social care workplaces. Data were gathered on target groups, intervention types and their effectiveness, and the outcomes of the interventions. We summarized this data thematically. The final review consisted of 76 studies. Mental health interventions primarily focused on health care workers rather than social care professionals. The interventions were mostly directed at individual workers, ignoring organizational-level interventions. They used a great variety of outcomes and questionnaires, and the questionnaires that measured the outcomes were used ambiguously. In most cases, the reported effectiveness of the studied interventions was incoherent, and many of the interventions had both statistically significant and non-significant effects. Evidence that interventions reduce the risk of work-related MHP is scarce. High-quality randomized controlled trials of interventions to promote mental health with more coherently formed outcomes are needed, especially on the organizational level. More interventions to improve social care professionals' mental health are also needed.

Young Adults and Sick Leave Length of Mental Illnesses

Objectives

The objective was to explore whether a sick leave length related to mental morbidity differs across different occupational categories.

Methods

In the analysis, registry of sick leaves was analyzed. Provided analysis is focused on the length of sick leaves related to mental diseases caused by substance use or other factors. Dependent variable is the sick leave length, and the independent variables are the categories of disease and occupation. Kruskal–Wallis test, Shapiro–Wilk test, and Brown–Forsythe (B–F) are used.

Results

There are differences in mental sick leave lengths caused by substance use or other factors. In the case of mental illnesses attributable to drugs, differences in the sick leave duration among different working groups were not found. Considering mental disorders caused by other factors, there are differences in the sick leave duration among different working groups.

Conclusions

There is no evidence of longer sick leave in people diagnosed with mental disorder related to substance use. Differences in occupational categories do not relate to sick leave length.

Identification of the return-to-work mode in unemployed workers with mental health issues: A focus group study among occupational health professionals

BACKGROUND: Return-to-work (RTW) perceptions and attitudes are predictive for future work participation in workers with mental health issues. OBJECTIVE: To identify what RTW perceptions and attitudes occupational health professionals recognize in sick-listed unemployed workers with mental health issues and how these perceptions and attitudes can be systematically assessed. METHODS: Four focus group sessions, each involving five-six different occupational health professionals, were held. The audio records were transcribed verbatim and coded by two researchers independently. A thematic analysis was conducted. RESULTS: Professionals recognized RTW perceptions and attitudes in sick-listed unemployed workers with mental health issues. These perceptions and attitudes were described as characteristics of three modes in a process regarding RTW: the passive, ambivalent and active RTW mode. A passive RTW mode includes perceptions about not being able to work and an expectant attitude. The ambivalent RTW mode is characterized by uncertainty and ambivalence regarding RTW with a desire for occupational support. Workers in an active RTW mode have positive RTW perceptions and show job search behavior. A main theme was the flexible nature of RTW attitudes and perceptions, with workers switching between the passive, ambivalent and active RTW modes. For the assessment of the RTW mode, the professionals preferred personal contact, possibly with support of a tool. This enables them to ask specific questions and to observe non-verbal signs. CONCLUSIONS: Recurring assessments of the RTW mode can be helpful in identifying unemployed workers with mental health issues at risk of long-term sickness absence and for starting targeted RTW interventions.

Effects of a Person-Centered eHealth Intervention for Patients on Sick Leave Due to Common Mental Disorders (PROMISE Study): Open Randomized Controlled Trial

BACKGROUND

Sick leave due to common mental disorders (CMDs) is a public health problem in several countries, including Sweden. Given that symptom relief does not necessarily correspond to return to work, health care interventions focusing on factors that have proven important to influence the return to work process, such as self-efficacy, are warranted. Self-efficacy is also a central concept in person-centered care.

OBJECTIVE

The aim of this study is to evaluate the effects of a person-centered eHealth intervention for patients on sick leave due to CMDs.

METHODS

A randomized controlled trial of 209 patients allocated to either a control group (107/209, 51.2%) or an intervention group (102/209, 48.8%) was conducted. The control group received usual care, whereas the intervention group received usual care with the addition of a person-centered eHealth intervention. The intervention was built on person-centered care principles and consisted of telephone support and a web-based platform. The primary outcome was a composite score of changes in general self-efficacy (GSE) and level of sick leave at the 6-month follow-up. An intention-to-treat analysis included all participants, and a per-protocol analysis consisted of those using both the telephone support and the web-based platform.

RESULTS

At the 3-month follow-up, in the intention-to-treat analysis, more patients in the intervention group improved on the composite score than those in the control group (20/102, 19.6%, vs 10/107, 9.3%; odds ratio [OR] 2.37, 95% CI 1.05-5.34; P=.04). At the 6-month follow-up, the difference was no longer significant between the groups (31/100, 31%, vs 25/107, 23.4%; OR 1.47, 95% CI 0.80-2.73; P=.22). In the per-protocol analysis, a significant difference was observed between the intervention and control groups at the 3-month follow-up (18/85, 21.2%, vs 10/107, 9.3%; OR 2.6, 95% CI 1.13-6.00; P=.02) but not at 6 months (30/84, 35.7%, vs 25/107, 23.4%; OR 1.8, 95% CI 0.97-3.43; P=.06). Changes in GSE drove the effects in the composite score, but the intervention did not affect the level of sick leave.

CONCLUSIONS

A person-centered eHealth intervention for patients on sick leave due to CMDs improved GSE but did not affect the level of sick leave.

Psychotherapeutic Consultation Services in the Workplace: A Longitudinal Analysis of Treatments and Sick Leave Using Health Insurance Data

BACKGROUND

Psychotherapeutic consultation services in the workplace (PSIW) have been developed to provide collaborative mental health care for employees. The aim of this study was to analyze participant characteristics, the role of PSIW in treatment courses, and the development of sick leave before and after PSIW start.

METHODS

Routine data from PSIW and health insurance of 155 participants were analyzed descriptively and by means of a multilevel negative binomial regression.

RESULTS

Eighty-four percent of users were male, and 72% were diagnosed with a mental disorder. The number of PSIW consultations varied from 1 to 13 (mean = 4). For 34% of participants, PSIW sessions were sufficient, 33% received a recommendation for outpatient psychotherapy, and 20% for inpatient mental health treatment. While recommendations for inpatient treatment displayed a high adherence rate (74%), recommendations for outpatient treatment were followed by 37%. Compared with the period of a half-year before PSIW, sick-leave days were reduced from the period of the second half-year after PSIW start and in the subsequent observed half-year periods. Trajectories of sick leave by subgroups showed differences.

CONCLUSIONS

PSIW is a flexible care offer, and results indicate a possible effect of PSIW on sick leave. In future studies, control group designs and inclusion of further variables are needed.

Metacognitive therapy and work-focused interventions for patients on sick leave due to anxiety and depression: study protocol for a randomised controlled wait-list trial

BACKGROUND

Common mental disorders such as depression and anxiety are major contributors to the global burden of disease. Affected individuals suffer reduced quality of life, impaired functioning and reduced capacity to work. Maintaining employment is an important determinant for health and wellbeing, and the economic impact of depression and anxiety is a significant societal expense. Treatments providing effective symptom reduction and helping patients return to work (RTW) would thus have substantial public health benefits. The present study will explore the effectiveness of metacognitive therapy (MCT) and work-focused interventions on reducing symptoms and increasing RTW rates for patients on sick leave due to depression and anxiety.

METHODS

The study is a randomised controlled wait-list trial (RCT; N = 240). The intervention group will receive protocol-based MCT and work-focused interventions immediately after inclusion. The control condition is a wait-list control group. All patients will receive up to 12 weekly sessions. The study context is a Norwegian outpatient clinic part of a national programme aimed at reducing sick leave. The co-primary outcomes are change in RTW and symptoms of depression and anxiety at the end of treatment. In addition to self-report, sick leave will also be collected from national registries from 2 years prior to intervention to 4 years after intervention. Symptoms of scores will be collected by self-report at pre- and post-treatment and at 6 and 12 months follow-up after treatment. A cost-effectiveness analysis will use total cost and quality-adjusted life-years as the secondary outcomes.

DISCUSSION

There is broad consensus on the importance of identifying treatment that effectively reduces depression and anxiety symptoms and aids RTW. This study is an important contribution to the field as it is the first RCT on MCT and work-focused interventions for patients on sick leave due to anxiety and depression.

Self-Reported Health in Patients on or at Risk of Sick Leave Due to Depression and Anxiety: Validity of the EQ-5D

Objectives: The EQ-5D is a generic, self-report measure of health that is increasingly used in clinical settings, including mental health. The EQ-5D captures health using five dimensions: Mobility, Self-care, Usual activities, Pain/discomfort, and Anxiety/Depression. The validity of the EQ-5D is previously unexplored in patients on or at risk of sick leave due to depression and anxiety. The study’s aim was to examine its validity in this group of patients.

Methods: Baseline data were collected from self-report questionnaires in an observational study (N=890) at a Norwegian outpatient-clinic. Participants were adults on or at risk of sick leave due to depression and anxiety who were referred for treatment by general practitioners. The crosswalk methodology was applied to estimate the EQ-5D value. Validity was assessed by comparing responses on the EQ-5D with the Beck Depression Inventory-II (BDI-II), the Beck Anxiety Inventory (BAI), and Subjective Health Complaints (SHC). An ordinal regression model was used to assess known-groups validity. Convergent validity was assessed using Pearson’s correlation coefficient, and a multivariate regression model that included sociodemographic characteristics.

Results: The mean EQ-5D value was 0.631, indicating reduced health status compared to “full health” anchored at 1.0, and patients reported moderate levels of depression and anxiety. Ordinal regression indicated that the EQ-5D could discriminate between different levels of symptom severity for depression and anxiety. The EQ-5D value showed significant correlation with the clinical measures; r=−0.52 for the BDI-II, r=−0.49 for the BAI, and r=−0.44 for SHC. The multivariate regression showed that the clinical variables significantly predicted the EQ-5D value, explaining 40.1% of the variance. Depression and anxiety scores were the largest determinants of EQ-5D value, respectively, whilst sick leave, subjective health complaints, and gender made moderate contributions.

Conclusion: The EQ-5D showed indication of validity in patients on or at risk of sick leave due to depression and anxiety in the present study. The EQ-5D value was sensitive to both symptom severity and functional impairment in the form of sick leave. The findings support the EQ-5D as a feasible and relevant measure of health status in these patients.

Education of the primary health care staff based on acceptance and commitment therapy is associated with reduced sick leave in a prospective controlled trial

Background

The use of cognitive behavioral therapy (CBT) to cope with mental distress and pain issues has helped many patients in primary health care in Sweden. However, the effects of CBT to reduce sick leave has not been equally convincing. Acceptance and Commitment Therapy (ACT) is an evolution of traditional CBT and we aimed to study if education based on ACT of the staff rather than the patients could reduce sick leave in primary health care.

Methods

This was a prospective trial in 6 primary health care centers in Kalmar (total amount of registered subjects of 28,930) in which the staff (physicians, nurses and therapists) received group-based education according to ACT during 2018 and 2019. The effects were compared with 5 similarly sized control health care centers in the neighboring Region of Jönköping in which no such education took place. The main aim was to study changes in sick leave in the 6 primary care centers of Kalmar and to keep track of more general trends by studying sick leave also in Jönköping, letting sick leave in the year 2017 to be the reference period for both areas.

Results

The staff at the health care centers in Kalmar reported to having attended a mean of 5.2 ± 2 educational ACT-sessions with psychiatrist Kadowaki in Kalmar. Sick leave for ICD-10 F43 (reaction to severe stress and related adjustment-disorders) was reduced from a mean value of 28.7 ± 9.1ongoing sick leaves/month in 2017 to 22.6 ± 7.0 sick leaves/month in 2018 (-21%, p = 0.033) and to 18.1 ± 10 sick leaves/month in 2019 (-37%, p = 0.038). The corresponding sick leave for any diagnosis (total sick leave) was reduced from 132 ± 39 sick leaves/month in 2017 to 118 ± 38 sick leaves/month in 2018 (-11%, p = 0.056) and to 102 ± 37 sick leaves/month in 2019 (-21%, p = 0.021). The corresponding sick leave comparisons in the control health centers did not show any significant changes (all p-values ≥ 0.24).

Conclusions

Total monthly mean sick leave was reduced 21% in the health care centers in Kalmar during the second year of the educational ACT intervention of the staff while it was unchanged in Jönköping. This suggests a significant effect to induce a reduction in long-term sick leave for patients in primary health care in which the staff received education according to ACT. The results of this trial could serve as a basis for a randomized trial in order to ascertain causality.

Sustained Attention and Working Memory Predict the Number of Days on Health-Related Benefits in the Year Following Occupational Rehabilitation

Purpose The objective of this study was to investigate the association between cognitive and emotional functioning and the number of days on health-related benefits such as sick leave, work assessment allowance and disability pension. We investigated whether cognitive and emotional functioning at the start of rehabilitation and the change from the start to the end of rehabilitation predicted the number of days on health-related benefits in the year after occupational rehabilitation. Methods A sample of 317 individuals (age 19-67 years), mainly diagnosed with a musculoskeletal or mental and behavioural ICD-10 disorder, participated. The sample was stratified depending on the benefit status in the year before rehabilitation. Those receiving health-related benefits for the full year comprised the work assessment allowance and disability pension (WAA) group and those receiving benefits for less than a year comprised the sick leave (SL) group. The participants were administered cognitive and emotional computerised tests and work and health questionnaires at the beginning and end of rehabilitation. The cumulative number of days on health-related benefits during 12 months after rehabilitation was the primary outcome variable and age, gender, educational level, subjective health complaints, anxiety, and depression were controlled for in multiple regression analyses. Results The WAA group (n = 179) was significantly impaired at baseline compared to the SL group (n = 135) in focused attention and executive function, and they also scored worse on work and health related variables. Higher baseline scores and change scores from the start to the end of rehabilitation, for sustained attention, were associated with fewer number of health-related benefit days in the WAA group, while higher baseline scores for working memory were associated with fewer number of health-related benefit days in the SL group. Conclusions New knowledge about attention and memory and return to work in individuals with different benefit status may pave the way for more targeted programme interventions. Rehabilitation programmes could benefit from designing interventions that respectively improve sustain attention and working memory related to working life in individuals on sick leave or work assessment allowance and disability pension.

Seeing an occupational health psychologist reduces sickness absence due to mental disorders: A quasi-experimental study

Mental health problems are a major public health and work-life issue. We examined in a quasi-experimental design whether occupational health psychologist (OHP) appointment reduces subsequent sickness absence (SA) due to mental disorders among younger Finnish employees. The present study was conducted among 18-39-year-old employees of the City of Helsinki using register data from the City of Helsinki and the Social lnsurance Institution of Finland. We examined differences in SA days due to mental disorders (ICD-10, F-diagnosed sickness allowances) between those treated (at least one OHP appointment for work ability support) and the comparison group (no OHP appointment) during a one-year follow-up. The full sample (n = 2286, 84% women) consisted of employees with SA due to a diagnosed mental disorder during 2008-2017. To account for the systematic differences between the treatment and comparison groups, the included participants were matched according to age, sex, occupational class, education, previous SA, occupational health primary care visits and psychotropic medication. The weighted matched sample included 1351 participants. In the weighted matched sample, the mean of SA days due to mental disorders was 11.4 (95% CI, 6.4-16.5) for those treated (n = 238) and 20.2 (95% CI, 17.0-23.4) for the comparison group (p < 0.01) during the follow-up year. The corresponding figures in the full sample were (11.1, 6.7-15.4) days for those treated (n = 288) and (18.9, 16.7-21.1) days for the comparison group (p < 0.01). This quasi-experimental study suggests that seeing an OHP to support work ability reduces SA due to mental disorders.

Understanding work participation among employees with common mental disorders: What works, for whom, under what circumstances and how? A systematic realist review protocol

BACKGROUND:

Work participation among employees with common mental disorders (CMDs) is an increasingly important, yet highly complex phenomenon. Given the call for preventing instead of reacting to negative work outcomes, there is a need to understand how employees with CMDs can continue working.

OBJECTIVES:

1) to provide insights in applying a realist approach to the literature review process and 2) to present a way to develop an explanatory framework on work participation, the related causal mechanisms and the interaction with the work context.

METHODS:

A systematic realist literature review, using stay at work (SAW) and work performance (WP) as outcomes of work participation. This protocol paper explains the rationale, tools and procedures developed and used for identification, selection, appraisal and synthesis of included studies.

RESULTS:

The review process entailed six steps to develop so called ‘middle range program theories’. Each step followed a systematic, iterative procedure using context-mechanism-outcome (CMO) configurations.

CONCLUSIONS:

Conducting a realist review adds on the understanding to promote work participation, by examining the heterogeneity and complexity of intervention- and observational studies. This paper facilitates other researchers within the field of occupational health by demonstrating ways to develop a framework on work participation using realist synthesis.

Spectrum, rate and unmet needs of sociomedical interventions in outpatient psychotherapy

OBJECTIVE

Psychological disorders often take a long-term course, resulting in impairment in daily life and work. Treatment must therefore target not only symptoms of illness but also capacity limitations and context restrictions, as outlined in the International Classification of Functioning, Disability and Health (ICF). This includes sociomedical and interdisciplinary interventions like coordination with other specialists, contact to employers and employment agencies, social support agencies, debt counselling, self-help and leisure groups. There are no data on the spectrum, rate and unmet needs of sociomedical interventions in outpatient psychotherapy.

METHOD

Following a semistructured interview schedule, 131 psychotherapists in private practice were asked to report on unselected patients. The interviewer assessed to what degree 38 predefined sociomedical interventions were applied so far or should be considered in the future.

RESULT

Reports for 322 patients were gathered. All sociomedical interventions were applied, depending on the sick leave status and course of illness. Cognitive behaviour therapists used more sociomedical interventions than psychodynamic therapists.

CONCLUSION

The data show that sociomedical interventions are a frequent part of psychotherapy. They are used preferably in patients with participation restrictions. Psychotherapeutic concepts and education should include sociomedical aspects.

Work-focused therapy for common mental disorders: A naturalistic study comparing an intervention group with a waitlist control group

BACKGROUND:

Common mental disorders (CMD) are leading causes of sickness absence. Treatments for CMD that both reduce symptoms and support work participation urgently need to be developed.

OBJECTIVE:

Determine the potential effects of work-focused therapy combining work interventions with either meta cognitive therapy or cognitive behavioural therapy (W-MCT/CBT) for patients with CMD on sick leave.

METHODS:

Naturalistic study with a quasi-experimental approach. Pre- and post-scores (return to work, symptoms, return-to-work self-efficacy, clinical recovery from depression and anxiety) were compared between the intervention group (n = 87) who received immediate treatment over an average of 10.40 sessions (SD = 3.09) and the non-randomized waitlist control group (n = 95) that had waited an average of 11.18 weeks (SD = 2.29).

RESULTS:

Significantly more patients returned fully to work in the intervention group (41.4%) than the control group (26.3%). Effect sizes for self-efficacy scores, depression and anxiety were large in the intervention group (d = 1.28, 1.01, 1.58), and significantly lower in the control group (d = 0.60, 0.14, 0.45). Significantly more patients in the treatment group than control group recovered from depression (54.1% vs. 12.8%) and anxiety (50.0% vs.10.6%).

CONCLUSIONS:

W-MCT/CBT may be an effective intervention for patients on sick leave due to CMD.

Developing a collaborative and sustainable return to work program for employees with common mental disorders: a participatory research with public and private organizations

PURPOSE

To disentangle the key steps of the return to work (RTW) process and offer clearer recovery-focused and sustainable RTW for people on sick leave due to common mental disorders (CMDs).

METHODS

This participatory research involves two large Canadian organizations. In each organization, we established an advisory committee composed of RTW stakeholders. We collected information in semi-structured interviews from RTW stakeholders (n = 26) with each member of the advisory committee in each organization, as well as with employees who had recently experienced CMDs. The interviews examined the RTW process for employees on sick leave due to CMDs as well as RTW stakeholders' perceptions of barriers and facilitators. A thematic approach was used to synthesize the data, following which, results were discussed with the two advisory committees to identify solutions considering key RTW steps.

RESULTS

Ten common key steps within the three RTW phases emerged from the semi-structured interviews with RTW stakeholders and discussions with the two advisory committees: 1) At the beginning of sickness absence and involvement of disability management team (phase 1), we found 3 steps (e.g., taking charge of the file), 2) during the involvement in treatment rehabilitation with health professionals and preparation of the RTW (phase 2), 4 steps (e.g., RTW preparation), and finally 3) the RTW and follow-up (phase 3) consists of 3 steps (e.g., gradual RTW).

CONCLUSION

A participatory study involving RTW stakeholders helped identify 10 common key steps within three phases to support RTW sustainability of people with CMDs. Future research will need to address how RTW coordinators intervene in the RTW process of employees with CMDs within these steps.IMPLICATIONS FOR REHABILITATIONRehabilitation professionals will benefit from a detailed description of the RTW process (10 steps spread out over 3 RTW phases), allowing them to standardize it while adopting a personalized approach for the employee on sick leave.Rehabilitation professionals are informed of stakeholders' role and actions required in the RTW process; as such the communication between RTW stakeholders should be improved.RTW coordinators will be able to tailor more precisely their intervention, considering the detailed RTW process and RTW stakeholders' role and actions, and thus will become the pivot occupational health specialists for the RTW process.

Enhanced Capacity to Act: Managers' Perspectives When Participating in a Dialogue-Based Workplace Intervention for Employee Return to Work

Purpose To explore if and how a dialogue-based workplace intervention with a convergence dialogue meeting can support a return to work process from the managers' perspective. Methods Individual interviews were conducted with 16 managers (10 women and 6 men) who had an employee on sick leave because of stress-induced exhaustion disorder. The manager and employee participated in a dialogue-based workplace intervention with a convergence dialogue meeting that was guided by a healthcare rehabilitation coordinator. The intervention aimed to facilitate dialogue and find concrete solutions to enable return to work. The interviews were analyzed by the Grounded Theory method. Results A theoretical model was developed with the core category enhancing managerial capacity to act in a complex return to work process, where the managers strengthened their agential capacity in three levels (categories). These levels were building competence, making adjustments, and sharing responsibility with the employee. The managers also learned to navigate in multiple systems and by balancing demands, control and support for the employee and themselves. An added value was that the managers began to take preventive measures with other employees. When sick leave was caused only by personal or social issues (not work), workplace actions or interventions were difficult to find. Conclusions From the managers' perspective, dialogue-based workplace interventions with a convergence dialogue meeting and support from a rehabilitation coordinator can strengthen managerial competence and capacity to act in a complex return to work process.

Efficacy of an indicated prevention strategy on sickness absence and termination of the employment contract: a 5-year follow-up study

Objective:

It was shown that an indicated prevention strategy (IPS), based on screening and early intervention, can considerably decrease future risk of long-term sickness absence (LTSA>28 days) over one year. Given the nature of the interventions, the potential of an effect extending beyond the original one year of follow-up might be present. This study aims to determine the efficacy of this IPS on LTSA and termination of employment contract over five years by extended follow up of IPS trials.

Methods:

Company records on sickness absence and termination of employment contract over five years were used from two randomized controlled trials (RCT) on the efficacy of the IPS (RCT I employees at high-risk for LTSA: intervention: N=263; RCT II high-risk employees with concurrent mild depressive complaints: intervention: N=139). Survival analysis was used to model time until the first LTSA episode and termination of employment contract.

Results:

RCT I showed a decrease of 43.2 days of sickness absence (P=0.05) and a lower 5-year risk of LTSA in the intervention, as compared to the control group [hazard ratio (HR) 0.61, 95% confidence interval (CI) 0.41–0.90], however no considerable impact on employment contract (HR 0.85, 95% CI 0.54–1.35) (intention-to-treat, ITT). For RCT II, we found no large difference in days of SA and no difference in LTSA risk over five years (HR 1.31, 95% CI 0.70–2.47), whereas the risk of termination of the employment contract was lower (HR 0.62, 95% CI 0.39–0.99) (ITT).

Conclusion:

Effects of the IPS were observed over five years, albeit differential between the two approaches. A combination of elements of both interventions might lead to optimal results but needs further study.

Sickness Absence and Sickness Presence Among Health and Care Employees in Sweden-Health Complaints, Health Behavior, and Future Long-Term Sickness Absence

OBJECTIVE

To describe if health complaints relate to health behavior in terms of sickness absence (SA) and sickness presence (SP) and to examine how complaints and health behavior predicts the risk for future long-term sickness absence (LTSA).

METHODS

Data originates from work environment surveys 2001 to 2013 and SA registers 2002 to 2016 of 1838 nurses, 7430 care assistants, and 40,515 individuals in all other occupations. Descriptive and regression analyses were conducted.

RESULTS

Physical complaints and high SA in combination with high SP increased the risk of LTSA among nurses and care assistants. Nurses' high SP and care assistants' high SA elevated the LTSA risk.

CONCLUSIONS

Strategies to reduce the reasons behind physical health complaints among health care workers are warranted. SP among nurses and SA among care assistants should be considered in the organization of their job demands.

A case management occupational health model to facilitate earlier return to work of NHS staff with common mental health disorders: a feasibility study

BACKGROUND

The NHS is the biggest employer in the UK. Depression and anxiety are common reasons for sickness absence among staff. Evidence suggests that an intervention based on a case management model using a biopsychosocial approach could be cost-effective and lead to earlier return to work for staff with common mental health disorders.

OBJECTIVE

The objective was to assess the feasibility and acceptability of conducting a trial of the clinical effectiveness and cost-effectiveness of an early occupational health referral and case management intervention to facilitate the return to work of NHS staff on sick leave with any common mental health disorder (e.g. depression or anxiety).

DESIGN

A multicentre mixed-methods feasibility study with embedded process evaluation and economic analyses. The study comprised an updated systematic review, survey of care as usual, and development of an intervention in consultation with key stakeholders. Although this was not a randomised controlled trial, the study design comprised two arms where participants received either the intervention or care as usual.

PARTICIPANTS

Participants were NHS staff on sick leave for 7 or more consecutive days but less than 90 consecutive days, with a common mental health disorder.

INTERVENTION

The intervention involved early referral to occupational health combined with standardised work-focused case management.

CONTROL/COMPARATOR

Participants in the control arm received care as usual.

PRIMARY OUTCOME

The primary outcome was the feasibility and acceptability of the intervention, study processes (including methods of recruiting participants) and data collection tools to measure return to work, episodes of sickness absence, workability (a worker's functional ability to perform their job), occupational functioning, symptomatology and cost-effectiveness proposed for use in a main trial.

RESULTS

Forty articles and two guidelines were included in an updated systematic review. A total of 49 of the 126 (39%) occupational health providers who were approached participated in a national survey of care as usual. Selected multidisciplinary stakeholders contributed to the development of the work-focused case management intervention (including a training workshop). Six NHS trusts (occupational health departments) agreed to take part in the study, although one trust withdrew prior to participant recruitment, citing staff shortages. At mixed intervention sites, participants were sequentially allocated to each arm, where possible. Approximately 1938 (3.9%) NHS staff from the participating sites were on sick leave with a common mental health disorder during the study period. Forty-two sick-listed NHS staff were screened for eligibility on receipt of occupational health management referrals. Twenty-four (57%) participants were consented: 11 (46%) received the case management intervention and 13 (54%) received care as usual. Follow-up data were collected from 11 out of 24 (46%) participants at 3 months and 10 out of 24 (42%) participants at 6 months. The case management intervention and case manager training were found to be acceptable and inexpensive to deliver. Possible contamination issues are likely in a future trial if participants are individually randomised at mixed intervention sites.

HARMS

No adverse events were reported.

LIMITATIONS

The method of identification and recruitment of eligible sick-listed staff was ineffective in practice because uptake of referral to occupational health was low, but a new targeted method has been devised.

CONCLUSION

All study questions were addressed. Difficulties raising organisational awareness of the study coupled with a lack of change in occupational health referral practices by line managers affected the identification and recruitment of participants. Strategies to overcome these barriers in a main trial were identified. The case management intervention was fit for purpose and acceptable to deliver in the NHS.

Standardized multimodal intervention for stress-induced exhaustion disorder: an open trial in a clinical setting

BACKGROUND

Long-term sick-leave due to stress-related ill-health is increasing in several economically developed countries. Even though different forms of interventions are administered in regular care for stress-related disorders, such as Stress-induced Exhaustion disorder (SED), the scientific evidence for the effectiveness of such treatments is sparse. The objective of this study was to explore changes in SED-symptoms and return-to-work-rates in a large group of SED-patients participating in a standardized Multimodal intervention (MMI) in a clinical setting.

METHOD

This open clinical trial tracked 390 patients who fulfilled the criteria for SED undergoing a 24-week MMI, including return-to-work-strategies. Before inclusion, all patients underwent a multi-professional assessment by a team of licensed physicians, licensed psychologists, and licensed physiotherapists. Self-rated questionnaires were administered before treatment, at treatment-start, mid-treatment, post-treatment, and at 12-month follow-up. Within-group change was evaluated over time with mixed-effects models. Beyond different symptoms, working time, sick-leave compensation, and adverse effects were also measured.

RESULTS

There were significant improvements in symptoms of SED, burnout, anxiety, depression, and insomnia, with large within-group effect sizes (d = 0.91-1.76), improvements that were maintained at 12-month follow-up. Furthermore, there was a significant increase in quality of life and large improvements in average working time and sick-leave compensation. Some adverse effects were reported, mainly concerning an increase in stress, anxiety, and worry.

CONCLUSION

SED-patients participating in this standardized MMI reported large symptom alleviation, increased working time and reduced sick-leave compensation, indicating a beneficial treatment. There were some adverse effects, but no more so than other psychological treatments. This study confirms previous findings that high levels of depression and anxiety decrease to sub-clinical levels during treatment, while symptoms of SED also decline, yet still persists above sub-clinical levels at 12-month follow-up. On the whole, this open clinical trial suggests that a standardized MMI, administered in a clinical setting, improves symptoms and return-to-work rates in a clinically representative SED-population.

Subjective cognitive complaints and sickness absence: A prospective cohort study of 7059 employees in primarily knowledge-intensive occupations

•

Subjective cognitive complaints predict sickness absence.

•

Age and prior absence also predict sickness absence in an additive fashion.

•

Maintenance of resources is important in knowledge-intensive occupations.

Knowledge-intensive work requires capabilities like monitoring multiple sources of information, prioritizing between competing tasks, switching between tasks, and resisting distraction from the primary task(s). We assessed whether subjective cognitive complaints (SCC), presenting as self-rated problems with difficulties of concentration, memory, clear thinking and decision making predict sickness absence (SA) in knowledge-intensive occupations. We combined SCC questionnaire results with reliable registry data on SA of 7743 professional/managerial employees (47% female). We excluded employees who were not active in working life, on long-term SA, and those on a work disability benefit at baseline. The exposure variable was the presence of SCC. Age and SA before the questionnaire as a proxy measure of general health were treated as confounders and the analyses were conducted by gender. The outcome measure was the accumulated SA days during a 12-month follow-up. We used a hurdle model to analyse the SA data. SCC predicted the number of SA days during the 12-month follow-up. The ratio of the means of SA days was higher than 2.8 as compared to the reference group, irrespective of gender, with the lowest limit of 95% confidence interval 2.2. In the Hurdle model, SCC, SA days prior to the questionnaire, and age were additive predictors of the likelihood of SA and accumulated SA days, if any. Subjective cognitive complaints predict sickness absence in knowledge-intensive occupations, irrespective of gender, age, or general health. This finding has implications for supporting work ability (productivity) among employees with cognitively demanding tasks.

An Internet-Delivered Cognitive Behavioral Therapy for Depression and Anxiety Among Clients Referred and Funded by Insurance Companies Compared With Those Who Are Publicly Funded: Longitudinal Observational Study

BACKGROUND

Anxiety and depression are leading causes of disability but are often undertreated. Internet-delivered cognitive behavioral therapy (ICBT) improves access to treatment by overcoming barriers to obtaining care. ICBT has been found to be efficacious in research trials and routine care, but there is limited research of ICBT when it is recommended and funded by insurance companies for clients on or recently in receipt of disability benefits or accommodations.

OBJECTIVE

The aim of this study was to examine ICBT engagement, treatment satisfaction, and effectiveness among individuals involved with 2 insurance companies. The 2 samples were benchmarked against published outcomes from a publicly funded (PF) ICBT clinic.

METHODS

Individuals who were on or recently in receipt of disability benefits and were either insurance company (IC) employees (n=21) or IC plan members (n=19) were referred to ICBT funded by the respective insurance companies. Outcomes were benchmarked against outcomes of ICBT obtained in a PF ICBT clinic, with clients in the clinic divided into those who reported no involvement with insurance companies (n=414) and those who were on short-term disability (n=44). All clients received the same 8-week, therapist-assisted, transdiagnostic ICBT course targeting anxiety and depression. Engagement was assessed using completion rates, log-ins, and emails exchanged. Treatment satisfaction was assessed posttreatment. Depression, anxiety, and disability measures were administered pretreatment, posttreatment, and at 3 months.

RESULTS

All samples showed high levels of ICBT engagement and treatment satisfaction. IC employees experienced significant improvement at posttreatment (depression d=0.77; anxiety d=1.13; and disability d=0.91) with outcomes maintained at 3 months. IC plan members, who notably had greater pretreatment disability than the other samples, experienced significant moderate effects at posttreatment (depression d=0.58; anxiety d=0.54; and disability d=0.60), but gains were not maintained at 3 months. Effect sizes at posttreatment in both IC samples were significantly smaller than in the PF sample who reported no insurance benefits (depression d=1.14 and anxiety d=1.30) and the PF sample who reported having short-term disability benefits (depression d=0.95 and anxiety d=1.07). No difference was seen in effect sizes among IC employees and the PF samples on disability. However, IC plan members experienced significantly smaller effects on disability d=0.60) compared with the PF sample with no disability benefits d=0.90) and those on short-term disability benefits d=0.94).

CONCLUSIONS

Many clients referred and funded by insurance companies were engaged with ICBT and found it acceptable and effective. Results, however, were not maintained among those with very high levels of pretreatment disability. Small sample sizes in the IC groups are a limitation. Directions for research related to ICBT funded by insurance companies have been described.

Effects of cognitive behavioural therapy and return-to-work intervention for patients on sick leave due to stress-related disorders: Results from a randomized trial

The aim of this study was to evaluate specific effects for patients with adjustment or exhaustion disorder, the Stress subgroup (n = 152), regarding symptom severity and sick leave after CBT, a return-to-work intervention (RTW-I), and a combination of them (COMBO), using data from a randomized trial. In the original study, primary care patients on sick leave (N = 211) were randomized to CBT (n = 64), RTW-I (n = 67), or COMBO (n = 80). Blinded Clinician Severity Rating (CSR) of symptoms and sick leave registry data were primary outcomes. Subgroup analyses showed that for the Stress subgroup, CBT led to greater reduction of symptoms than RTW-I posttreatment, but COMBO did not differ from CBT or RTW-I. Regarding sick leave, there was no difference between treatments in the Stress subgroup. An exploratory analysis of the treatment effects in a subgroup of patients with depression, anxiety or insomnia indicates that RTW-I reduced sick leave faster than CBT. We conclude that CBT may be promising as an effective treatment of stress and exhaustion disorder.

Work-directed rehabilitation or physical activity to support work ability and mental health in common mental disorders: a pilot randomized controlled trial

Objective:

To evaluate feasibility and potential effectiveness of work-directed rehabilitation in people with common mental disorders.

Design:

Pilot randomized controlled trial.

Setting:

Primary healthcare, Sweden.

Subjects:

Working adults ( n = 42) of mean age 46.2 ± 11.1 years with depression or anxiety disorder.

Interventions:

Eight weeks of work-directed rehabilitation ( n = 21) or physical activity ( n = 21). Work-directed rehabilitation included sessions with a physiotherapist and/or an occupational therapist, to develop strategies to cope better at work. Physical activity included a planning session and access to a local gym.

Main measures:

Feasibility: attendance, discontinuation and adverse events. Measurements were the Work Ability Index, the Global Assessment of Functioning, the Montgomery–Asberg Depression Rating Scale, the Beck Anxiety Inventory and the World Health Organization—Five Well-Being Index.

Results:

Attendance to rehabilitation sessions was 88% ( n = 147/167) and discontinuation rate was 14% ( n = 3/21). No serious adverse events were reported. Within both groups, there was a significant improvement in Work Ability Index score (mean change: 3.6 (95% confidence interval (CI): 0.45, 6.7) in work-directed rehabilitation and 3.9 (95% CI: 0.9, 7.0) in physical activity) with no significant difference between groups. For the other outcomes, significant improvements were found within but not between groups. Per-protocol analysis showed a trend toward the antidepressant effect of work-directed rehabilitation compared to physical activity (mean difference in depression score −3.1 (95% CI: −6.8, 0.4), P = 0.075).

Conclusion:

Work-directed rehabilitation was feasible to persons with common mental disorders and improved their work ability and mental health. Comparable improvements were seen in the physical activity group. Suggested modifications for a larger trial include adding a treatment-as-usual control.

Occupational Rehabilitation Is Associated With Improvements in Cognitive Functioning

Introduction

Occupational rehabilitation may be offered to workers on long-term sick leave who often report problems with cognitive functioning, anxiety, depression, pain, and reduced work ability. The empirical knowledge is sparce on how occupational rehabilitation may influence cognitive and emotional functioning and patients have not previously been subjected to comprehensive objective testing. The main aim of this study was to assess possible changes in cognitive and emotional functioning such as memory, attention, executive function, and emotion recognition among patients in occupational rehabilitation.

Methods

A large sample of 280 sick-listed workers referred to inpatient and outpatient occupational rehabilitation was recruited. The rehabilitation programs had a mean duration of 28 days and comprised physical activity, cognitive behavior treatment components and collaboration with the workplace. A pre-post design was applied to investigate possible changes in cognitive and emotional functioning (primary outcomes) and work and health measures (secondary outcomes), comparing the rehabilitation group with a control group of 70 healthy workers. Individuals in the control group were tested at random time points with an approximately 28 day interval between pre- and post-test, thus coinciding with the duration of rehabilitation. Repeated measures analysis of variance was used for the main analyses.

Results

Compared to the control group, the rehabilitation group had greater gains from pre- to post-test in focused and sustained attention, as well as greater improvements in work ability and reduction in subjective health complaints (SHC), helplessness, pain, pain related to work, anxiety, and depression. In the rehabilitation group, exploratory correlational analysis indicated that improvements in focused and sustained attention were associated with improvements in return-to-work self-efficacy, work ability as well as a reduction in SHC.

Conclusion

The sick-listed workers improved in focused and sustained attention and work and health measures after participating in occupational rehabilitation. This study is one of the first to systematically investigate changes in cognitive and emotional functioning during occupational rehabilitation. Clinical practice should benefit from increased knowledge about all cognitive functions and should be specifically aware of the improvements in focused and sustained attention, while memory, executive function and emotion recognition remained unchanged. The results can be used as a motivation to tailor specific interventions to gain further improvements in all cognitive and emotional functions.

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.

Meaning in life buffers the association between clinical anxiety and global maladjustment in participants with common mental disorders on sick leave

An important goal of mental health specialists is to improve the quality of life and the adaptation of people with common mental disorders on sick leave. Meaning in life is a protective factor for people adjusting to distress and negative events. This study explores the buffering role of meaning in life in the relationship between clinical anxiety or negative affect and maladjustment in participants with common mental disorders on sick leave. The sample was 167 participants with Adjustment, Anxiety and, Depressive Disorders; n = 115 were women and n = 52 men. Participants' mean age M = 42.16 (SD = 9.91) years. We performed zero-order correlations and hierarchical regression analyses. Meaning in life moderated and buffered the association between clinical anxiety or negative affect and global maladjustment to daily life. These findings suggest that Meaning in life is a relevant variable in the adjustment of common mental disorders on sick leave.

Early intervention with cognitive behavioral therapy reduces sick leave duration in people with adjustment, anxiety and depressive disorders

Background: Early intervention in workers diagnosed with mental disorders is associated with a lower incidence of relapse and shorter sick leave. However, no studies have been carried out on the effect of early intervention using an evidence-based therapy, Cognitive Behavioral Therapy (CBT), on people with sick leave.Aims: The objectives of the present study are to study whether the type of intervention (early or late) will affect the total duration of the sick leave, the partial duration of the sick leave, the duration of the psychotherapy and the time until return to work after the psychotherapy ends. The sample was composed of 167 participants who were on sick leave for adjustment disorders, anxiety disorders or depressive disorder.Results: The participants who had early intervention with CBT had a significantly shorter duration of total sick leave and partial sick leave, and a shorter time until returning to work after the psychotherapy ended than those who had late intervention. There were no statistically differences in the duration or efficacy of the psychotherapy.Conclusion: We can suggest that providing early access to CBT significantly reduces the length of sick leave in patients with mental disorders.
