Current state of vocationally oriented medical rehabilitation – a German perspective

Pre-rehabilitation sense of coherence as a predictor of symptom change after rehabilitation

Sense of coherence (SOC) constitutes the key component of salutogenesis theory. It reflects individuals' confidence that their environment is comprehensible and manageable and that their lives are meaningful. Research demonstrates a strong cross-sectional relationship between SOC and mental health. However, little is known about SOC's temporal stability and its potential to predict changes in psychopathological symptom severity in different settings. The goal of the current study was to address this gap. The sample of the two-wave longitudinal study consists of 294 patients receiving inpatient psychotherapeutic (and psychopharmacological) treatment for various psychological disorders at a German psychosomatic rehabilitation clinic. SOC (Antonovsky, Social Science & Medicine, 1993, 36, 725-733) and outcome measures (i.e., general mental health problems, depression and anxiety symptoms) were assessed within two days of arrival and at the end of rehabilitation (week 5/6). SOC was significantly enhanced after treatment whereas psychopathological symptoms were significantly reduced. Regression analyses revealed that pre-treatment SOC was a significant negative predictor of post-treatment symptom severity for all outcome measures even after controlling for pre-treatment symptoms. The current findings provide first evidence that SOC is a significant unique predictor of symptom change. Future studies need to further investigate longitudinal associations between SOC and mental health outcomes in different settings.

Identifying Expectations of Delayed Return to Work in Patients with Prostate Cancer at the Beginning of a Cancer Rehabilitation Program

Purpose To investigate factors associated with expectations of delayed return to work (RTW) in patients with prostate cancer recently admitted to a cancer rehabilitation program. Methods In this multicenter study, data about expected time until RTW and potential correlates (personal, medical, psychosocial and work-related factors) were obtained from 822 employed cancer rehabilitation participants at the beginning of the program. Participants expecting early RTW (≤ 3 months) and delayed RTW (> 3 months) were compared. Hierarchical multivariate logistic regression was applied to study which factors are associated with expecting delayed RTW. Results In total, 171 cancer rehabilitation participants (21%) expected delayed RTW. Group comparison showed education, type of occupation, income, number of comorbid conditions, tumor stage according to the staging system of the Union for International Cancer Control (UICC), anxiety and depression, quality-of-life functioning scales, urinary and treatment-related symptoms, duration of sick leave, subjective work ability, perceived ability to return to the former job, intention to apply for a disability pension, effort-reward-imbalance and occupational stress to be associated in bivariate analysis with participants' expectations. Multivariate analysis revealed UICC tumor stage III (compared to stages I/II, OR 2.36), lower subjective work ability (OR 0.82), perceived inability to return to the former job (OR 1.88) and intention to apply for a disability pension (OR 1.94) to increase the likelihood of expecting delayed RTW. Conclusions Negative or non-beneficial RTW expectations, which are related to self-perception and behavioral intention, seem to be key factors for expecting delayed RTW. Interventions to early identify and adjust such expectations might empower cancer rehabilitation participants to develop appropriate expectations for work recovery.

Effects of nationwide implementation of work-related medical rehabilitation in Germany: propensity score matched analysis

Objectives

Since 2014, the Federal German Pension Insurance has approved several departments to implement work-related medical rehabilitation programmes across Germany. Our cohort study was launched to assess the effects of work-related medical rehabilitation under real-life conditions.

Methods

Participants received either a common or a work-related medical rehabilitation programme. Propensity score matching was used to identify controls that were comparable to work-related medical rehabilitation patients. The effects were assessed by patient-reported outcome measures 10 months after completing the rehabilitation programme.

Results

We compared 641 patients who were treated in work-related medical rehabilitation with 641 matched controls. Only half of the treated patients had high initial work disability risk scores and were intended to be reached by the new programmes. The dose of work-related components was on average in accordance with the guideline; however, the heterogeneity was high. Work-related medical rehabilitation increased the proportion of patients returning to work by 5.8 percentage points (95% CI 0.005 to 0.110), decreased the median time to return to work by 9.46 days (95% CI -18.14 to -0.79), and improved self-rated work ability by 0.38 points (95% CI 0.05 to 0.72) compared with common medical rehabilitation. A per-protocol analysis revealed that work-related medical rehabilitation was more effective if patients were assigned according to the guideline and the minimal mandatory treatment dose was actually delivered.

Conclusions

The implementation of work-related medical rehabilitation in German rehabilitation centres affected work participation outcomes. Improving guideline fidelity (reach and dose delivered) will probably improve the outcomes in real-world care.

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

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

Factors Associated With Success in an Occupational Rehabilitation Program for Work-Related Musculoskeletal Disorders

Work-related musculoskeletal disorders are a significant burden; however, no consensus has been reached on how to maximize occupational rehabilitation programs for people with these disorders, and the impact of simulating work tasks as a mode of intervention has not been well examined. In this retrospective cohort study, the authors used logistic regression to identify client and program factors predicting success for 95 clients in a general occupational rehabilitation program and 71 clients in a comprehensive occupational rehabilitation program. The final predictive model for general rehabilitation included gender, number of sessions completed, and performance of work simulation activities. Maximum hours per session was the only significant predictor of success in the comprehensive rehabilitation program. This study identifies new factors associated with success in occupational rehabilitation, specifically highlighting the importance of intensity (i.e., session length and number of sessions) of therapy and occupation-based activities for this population.

Addressing Work-Related Issues in Medical Rehabilitation: Revision of an Online Information Tool for Healthcare Professionals

Background. Medical rehabilitation increasingly considers occupational issues as determinants of health and work ability. Information on work-related rehabilitation concepts should therefore be made available to healthcare professionals. Objective. To revise a website providing healthcare professionals in medical rehabilitation facilities with information on work-related concepts in terms of updating existing information and including new topics, based on recommendations from implementation research. Method. The modification process included a questionnaire survey of medical rehabilitation centers (n = 28); two workshops with experts from rehabilitation centers, health payers, and research institutions (n = 14); the selection of new topics and revision of existing text modules based on expert consensus; and an update of good practice descriptions of work-related measures. Results. Health payers' requirements, workplace descriptions, and practical implementation aids were added as new topics. The database of good practice examples was extended to 63 descriptions. Information on introductory concepts was rewritten and supplemented by current data. Diagnostic tools were updated by including additional assessments. Conclusions. Recommendations from implementation research such as assessing user needs and including expert knowledge may serve as a useful starting point for the dissemination of information on work-related medical rehabilitation into practice. Web-based information tools such as the website presented here can be quickly adapted to current evidence and changes in medicolegal regulations.

Work-related medical rehabilitation in patients with musculoskeletal disorders: the protocol of a propensity score matched effectiveness study (EVA-WMR, DRKS00009780)

Background

Musculoskeletal disorders are one of the most important causes of work disability. Various rehabilitation services and return-to-work programs have been developed in order to reduce sickness absence and increase sustainable return-to-work. As the effects of conventional medical rehabilitation programs on sickness absence duration were shown to be slight, work-related medical rehabilitation programs have been developed and tested. While such studies proved the efficacy of work-related medical rehabilitation compared with conventional medical rehabilitation in well-conducted randomized controlled trials, its effectiveness under real-life conditions has yet to be proved.

Methods/Design

The cohort study will be performed under real-life conditions with two parallel groups. Participants will receive either a conventional or a work-related medical rehabilitation program. Propensity score matching will be used to identify controls that are comparable to treated work-related medical rehabilitation patients. Over a period of three months, about 18,000 insured patients with permission to undergo a musculoskeletal rehabilitation program will be contacted. Of these, 15,000 will receive a conventional and 3,000 a work-related medical rehabilitation. We expect a participation rate of 40 % at baseline. Patients will be aged 18 to 65 years and have chronic musculoskeletal disorders, usually back pain. The control group will receive a conventional medical rehabilitation program without any explicit focus on work, work ability and return to work in diagnostics and therapy. The intervention group will receive a work-related medical rehabilitation program that in addition to common rehabilitation treatments contains 11 to 25 h of work-related treatment modules. Follow-up data will be assessed three and ten months after patients’ discharge from the rehabilitation center. Additionally, department characteristics will be assessed and administrative data records used. The primary outcomes are sick leave duration, stable return to work and subjective work ability. Secondary outcomes cover several dimensions of health, functioning and coping strategies.

Discussion

This study will determine the relative effectiveness of a complex, newly implemented work-related rehabilitation strategy for patients with musculoskeletal disorders.

Effectiveness of work-related medical rehabilitation in cancer patients: study protocol of a cluster-randomized multicenter trial

Background

Work is a central resource for cancer survivors as it not only provides income but also impacts health and quality of life. Additionally, work helps survivors to cope with the perceived critical life event. The German Pension Insurance provides medical rehabilitation for working-age patients with chronic diseases to improve and restore their work ability, and support returning to or staying at work, and thus tries to sustainably avoid health-related early retirement. Past research showed that conventional medical rehabilitation programs do not support returning to work sufficiently and that work-related medical rehabilitation programs report higher return-to-work rates across several health conditions, when compared to medical rehabilitation. Therefore, the current study protocol outlines an effectiveness study of such a program for cancer survivors.

Methods

To evaluate the effectiveness of work-related medical rehabilitation in cancer patients we conduct a cluster-randomized multicenter trial. In total, 504 rehabilitation patients between 18 and 60 years with a Karnofsky Performance Status of ≥70 %, a preliminary positive social-medical prognosis of employability for at least 3 h/day within the next 6 months and an elevated risk of not returning to work will be recruited in four inpatient rehabilitation centers. Patients are randomized to the work-related medical rehabilitation program or the conventional medical rehabilitation program based on their week of arrival at each rehabilitation center. The work-related medical rehabilitation program comprises additional work-related diagnostics, multi-professional team meetings, an introductory session as well as work-related functional capacity training, work-related psychological groups, and social counseling. All additional components are aimed at the adjustment of the patients’ capacity in relation to their individual job demands. Role functioning defines the main study outcome and will be assessed with the EORTC-QLQ30. Secondary outcome measures are the remaining scales of the EORTC-QLQ30, fatigue, self-rated work ability, disease coping, participation in working life, realization of work-related goals and therapies during rehabilitation, and treatment satisfaction.

Discussion

A positive evaluation of work-related medical rehabilitation in cancer patients is expected due to the promising findings on the effectiveness of such programs for patients with other health conditions. Results may support the dissemination of work-related medical rehabilitation programs in German cancer rehabilitation.

The reliability of WorkWell Systems Functional Capacity Evaluation: a systematic review

Background

Functional capacity evaluation (FCE) determines a person’s ability to perform work-related tasks and is a major component of the rehabilitation process. The WorkWell Systems (WWS) FCE (formerly known as Isernhagen Work Systems FCE) is currently the most commonly used FCE tool in German rehabilitation centres. Our systematic review investigated the inter-rater, intra-rater and test-retest reliability of the WWS FCE.

Methods

We performed a systematic literature search of studies on the reliability of the WWS FCE and extracted item-specific measures of inter-rater, intra-rater and test-retest reliability from the identified studies. Intraclass correlation coefficients ≥ 0.75, percentages of agreement ≥ 80%, and kappa coefficients ≥ 0.60 were categorised as acceptable, otherwise they were considered non-acceptable. The extracted values were summarised for the five performance categories of the WWS FCE, and the results were classified as either consistent or inconsistent.

Results

From 11 identified studies, 150 item-specific reliability measures were extracted. 89% of the extracted inter-rater reliability measures, all of the intra-rater reliability measures and 96% of the test-retest reliability measures of the weight handling and strength tests had an acceptable level of reliability, compared to only 67% of the test-retest reliability measures of the posture/mobility tests and 56% of the test-retest reliability measures of the locomotion tests. Both of the extracted test-retest reliability measures of the balance test were acceptable.

Conclusions

Weight handling and strength tests were found to have consistently acceptable reliability. Further research is needed to explore the reliability of the other tests as inconsistent findings or a lack of data prevented definitive conclusions.

Workers with a chronic disease and work disability. Problems and solutions

The prevalence of chronic diseases in the age group 18-65 years is high. Cardiometabolic conditions and musculoskeletal diseases are the most frequent chronic diseases. Depending on disease and comorbidity, the employment rates are considerably lower than for healthy individuals. Chronically ill workers may have problems in meeting job demands, they may experience physical, cognitive or sensory limitations, have fatigue or pain complaints or other disease symptoms. Psychological distress, depressive feelings, feelings of shame or guilt, lack of coping or communicative skills, and non-supportive colleagues and supervisors may add to work-related problems. The ICF Model (International Classification of Functioning, Disability and Health) of the WHO offers a framework for understanding and considering health-related problems at work and finding solutions. Interventions to prevent problems in functioning, sickness absence and work disability may focus on the worker, the workplace, or health care. Multidisciplinary vocational rehabilitation, exercise therapy, cognitive behavioural interventions, workplace interventions and empowerment are interventions with at least some evidence of effectiveness. Future policy could focus more on promotion of workers' health and future research should include the interests and motivations of employers concerning disability management, skills of line managers, the feasibility of interventions to prevent work disability and the context sensitivity of study outcomes.
