[Facilitating and Hindering Factors in the Implementation of Medical Rehabilitation of Adolescents with Scoliosis before and during the SARS-CoV-2 Pandemic: A Qualitative Study]. / Förderliche und hinderliche Faktoren für die Durchführung der medizinischen Rehabilitation bei Jugendlichen mit Skoliose vor und während der SARS-CoV-2-Pandemie: Eine qualitative Studie.

PURPOSE: Based on the experience during the SARS-CoV-2 pandemic, the study aimed to derive facilitating and hindering factors in the implementation of medical rehabilitation during future pandemics in adolescents with scoliosis. METHODS: A qualitative study design with guided expert interviews was chosen. Twelve interviews with adolescents and seven interviews with physiotherapists were conducted. The evaluation was carried out using qualitative content analysis according to Mayring and inductive categorization. RESULTS: For 83.3% of the adolescents a therapy considering individual patient needs was a facilitator. Good information management (91.7%), continued availability of leisure activities (66.7%), and a high perception of safety (100%) were facilitating. 71.4% favoured outdoor therapy. The increased exertion caused by wearing a mask (91.7%) and the shortened therapy times (66.7%) were seen as barriers. For 75.0% of the adolescents, social contacts were more difficult. All therapists stated that communication between patients and therapists was more difficult. CONCLUSION: For successful rehabilitation during the SARS-CoV-2 pandemic, depending on weather conditions, therapy should be outside, as there is no need to wear mouth-nose protection outdoors. In addition, the physiotherapeutic treatment (Schroth therapy) should be carried out without mask due to the intensity of the exercise. Social contacts among all adolescents should be supported as much as possible. The leisure activities should provide a wide choice and enough free places. Continuation of certain hygienic measures could help to reduce the incidence of illnesses (e. g., gastrointestinal infections) in the future. These were barely noticed in rehabilitation facilities during the pandemic.

Use of a job exposure matrix to predict the risk of work disability in individuals with back pain: An inception cohort study.

BACKGROUND: Low back pain has a high economic burden in Germany due to back pain-related sick leave, disability pensions, and health care utilization. Work-related factors can predict disabling back pain. Job exposure matrices can be used to consider job demands and occupational characteristics in routine data analysis. OBJECTIVE: This longitudinal analysis tested whether rehabilitation utilization due to musculoskeletal disorders is associated with occupation-linked job exposures in employees with back pain. METHODS: Data from a German cohort study were used, including employees aged 45 to 59 years with self-reported back pain in the last three months. Individuals' job titles were assessed in the baseline survey in 2017 and matched with parameters of aggregated job exposure indices. Administrative data from the German Pension Insurance were used to extract information on rehabilitation utilization. Proportional hazard models tested the associations. RESULTS: We considered data of 6,569 participants (mean age: 52.3 years; 57.7% women). During follow-up, with a maximum of 21 months, 296 individuals (4.5%) utilized medical rehabilitation due to musculoskeletal disorders. Adjusted analyses showed that high physical (HR = 2.87; 95% CI 1.74; 4.75) and overall (HR = 2.34; 95% CI 1.44; 3.80) job exposures were associated with a higher risk of rehabilitation utilization. CONCLUSION: Individuals with back pain working in occupations with high physical job exposures have a higher risk for rehabilitation utilization. To prevent work disability in individuals with back pain, occupational groups with high physical job exposures should be actively informed about tailored intervention options.

Sequences of vocational rehabilitation services in Germany: a cohort study.

BACKGROUND: This study aimed to describe sequences of vocational rehabilitation services among individuals with approved vocational rehabilitation in Germany and to identify typical service sequences. METHODS: We used administrative data on vocational rehabilitation services and questionnaire data on health and work ability to describe frequencies and sequences of vocational rehabilitation services financed by the Federal German Pension Insurance. Through sequence analysis, we were able to map the service sequences. We did cluster analyses to identify typical different service sequences. RESULTS: Our sample included 1,652 individuals with 2,584 services. Integration services and two-year vocational retraining were the most common services. We could identify three different service clusters around integration services: shorter ones, followed by employer benefits and without employer benefits. We found two different clusters around two-year vocational retraining: shorter and longer clusters. Two-year vocational retraining was more often initiated by preparatory services and followed by employer benefits than integration services. Longer services in both clusters were associated with better baseline data for physical health, work ability, risk of future work disability, and younger age than shorter services. People in two-year-vocational retraining reported at baseline better general health, better work ability, low risk of future work disability, and less mental illness compared to people in integration services. CONCLUSIONS: Multiple services, that is, sequences of services, were more likely to occur among individuals with more complex services like two-year vocational retraining. Utilization of complex services and longer services was influenced by health, age, risk of future work disability, and education.

[Work Participation after Multimodal Rehabilitation due to Cancer: Representative Analyses using Routine Data of the German Pension Insurance]. / Berufliche Teilhabe nach einer medizinischen Rehabilitation aufgrund von onkologischen Erkrankungen: Repräsentative Analysen auf Basis der Routinedaten der Deutschen Rentenversicherung.

PURPOSE: Cancer diseases are associated with multiple physical, psychosocial, and occupational burdens that jeopardize work participation and must be specifically addressed with rehabilitative interventions. This study addressed the following questions regarding cancer patients whose rehabilitation was covered by German Pension Insurance (GPI): (a) What socio-medical risks existed prior to rehabilitation, (b) how well persons were able to return to work after rehabilitation, and (c) what conditions determined work participation? METHODS: We used the rehabilitation statistics database of the German Pension Insurance and included patients with completed medical rehabilitation due to cancer in 2017. Analyses were carried out for the entire group as well as for those differentiated according to their tumor sites (breast, prostate, colon and lung). Work participation was operationalized both via a monthly state up to 24 months after rehabilitation discharge and as a rate of all persons who were employed 12 or 24 months and the 3 preceding months (stable work participation). For the analysis of the influencing factors on stable work participation, multiple logistic regression models with stepwise inclusion were calculated separately for the rates after 12 and 24 months. RESULTS: A total of 63,587 data sets were included in the analysis (breast cancer: n=20,545, 32%; prostate: n=6,434, 10%; colon: n=4,727, 7%; lung: n=2,866, 5%). Of the rehabilitation participants 55% (lung), 49% (colon), 46% (breast), and 13% (prostate) had sickness absences of six or more months in the year before rehabilitation. Two years after rehabilitation, return-to-work rates were 66% (breast), 54% (prostate), 50% (colon), and 24% (lung). The strongest factors influencing stable work participation were time of sick leave, wage before rehabilitation and age. CONCLUSION: Two years after cancer rehabilitation, 5 to 6 out of 10 persons returned to stable work participation. Relevant influencing factors were the length of sick leave and wages prior to cancer rehabilitation. The results suggest inclusion of more work-related aspects in cancer rehabilitation and greater suppor, especially in the first year post-rehabilitation.

Contextual factors in persistent severe back pain: A longitudinal analysis among German employees.

BACKGROUND: Chronic back pain in employees compromises participation in social and daily activities, as well as work. OBJECTIVES: To examine the severity of back pain after 2 years and identify factors predicting stagnation at this level of pain. METHODS: Data were derived from a prospective cohort study with randomized sampling of insurants in the German Pension Insurance using a questionnaire at baseline and follow-up after 2 years. The sample consisted of middle-aged employees (45-59 years) with strong limitations due to back pain (Chronic Pain Grade III or IV), who had not applied for disability pension and did not use medical rehabilitation in the previous 4 years before baseline. Stepwise multivariable logistic regression models with backwards selection were used to identify relevant contextual factors in the stagnation of severe back pain. RESULTS: Of 1208 persons with severe back pain at baseline, 48% had stagnated at that pain level after 2 years. Predictors of persistent severe back pain were older age, poorer general health, more additional disabling conditions, more depressive symptoms, caregiving burden, less pain-related self-efficacy and more fear avoidance beliefs. CONCLUSIONS: In a high-risk subgroup with several co-existing conditions, this analysis highlights (mental) health, social and personal (contextual) factors associated with long-term unfavourable back pain progression. SIGNIFICANCE: Back pain is a condition that often has a chronic or recurrent course, threatening participation in many areas of life. In this study it was found that the unfavourable condition of severe back pain can remain stable for long periods of time in a significant proportion of sufferers. Contextual factors (self-efficacy, fear-avoidance beliefs, caregiving burden) as well as additional health problems should be considered when identifying persons with stagnating pain courses.

Psychological interventions during breast cancer rehabilitation: a randomized controlled trial comparing structured short-term psychotherapy versus non-specific group discussion.

PURPOSE: Psycho-oncological treatment is recommended in cancer rehabilitation as it improves fatigue, anxiety, depression, and quality of life in breast cancer patients. The aim of our study was to compare a structured short-term psychotherapy and a non-specific group discussion provided during breast cancer rehabilitation. METHODS: Breast cancer patients were randomly assigned to structured group short-term psychotherapy or a non-specific group discussion during breast cancer rehabilitation. The patients completed questionnaires at the beginning and end of rehabilitation and three months after rehabilitation. The primary outcome was anxiety. Secondary outcomes were depression, distress, fatigue and health-related quality of life domains. RESULTS: In total, 160 patients (80 in both groups) were recruited and included in the analysis. There was no significant difference between both groups in the primary outcome anxiety at the end of rehabilitation (difference = -0.2; 95% CI -1.2 to 0.7) and three months after rehabilitation (difference = 0.2; 95% CI -0.9 to 1.3) and in any secondary outcome. Patients in the short-term psychotherapy group with high anxiety levels at baseline reported fewer depressive symptoms at the end of rehabilitation. CONCLUSIONS: Our study showed no difference between structured short-term psychotherapy and a non-specific group discussion. Patients with high baseline anxiety levels were more likely to benefit from short-term structured psychotherapy. Early identification of this subgroup and symptoms of mental illness should occur after initial treatment in breast cancer patients in order to offer a structured treatment for anxiety and depressive symptoms during rehabilitation.

[Holistic clarification of the need for intervention at the interface of rehabilitation and occupational medicine when work participation is at risk]. / Ganzheitliche Klärung des Interventionsbedarfs bei gefährdeter beruflicher Teilhabe an der Schnittstelle von Rehabilitation und Betriebsmedizin: Eine Machbarkeitsstudie.

Introduction: For employees whose work participation is at risk, a comprehensive and workplace-oriented diagnosis is required in order to understand the health problems and to support affected persons with individual solutions. We developed a novel diagnostic service to ensure work participation that combines rehabilitative and occupational health medicine. The aim of this feasibility study was to evaluate the implementation and to analyze changes in health and working ability. Methods: The observational study (German Clinical Trials Register: DRKS00024522) included employees with health restrictions and limited working ability. Participants received an initial consultation from an occupational health physician, a 2-day holistic diagnostics work-up at a rehabilitation center and up to four follow-up consultations. Questionnaire data collected at the initial consultation and at the first and last follow-up consultations included subjective working ability (0-10 points) and general health (0-10). Results: Data from 27 participants were analyzed. The participants were 63% female and on average 46 years old (standard deviation, SD = 11.5). From the initial consultation to the final follow-up consultation, participants reported improvement in their general health (difference = 1.52; 95% confidence interval. CI: 0.37-2.67; d = 0.97). Discussion and conclusion: The model project GIBI offers low-threshold access to a confidential, comprehensive and workplace-oriented diagnostic service to support work participation. Successful implementation of GIBI requires intensive cooperation between occupational health physicians and rehabilitation centers. To evaluate the effectiveness, a randomized controlled trial (n = 210) with a waiting list control group is currently underway.

Utilisation of rehabilitation due to mental disorders during the SARS-CoV-2 pandemic: a difference-in-differences analysis.

BACKGROUND: Our analyses examined the extent to which the use of rehabilitation for patients with mental disorders decreased due to the COVID-19 pandemic in Germany. METHODS: We used monthly cross-sectional administrative data on rehabilitation utilisation due to mental disorders in 2019 and 2020 and estimated a difference-in-differences model to determine the reduction in rehabilitation utilisation attributable to the pandemic. RESULTS: We included 151,775 rehabilitations in 2019 and 123,229 rehabilitations in 2020 in our analysis. The number of rehabilitations decreased from April to December by 14.2% due to the pandemic (March to December: 21.8%). The decline was more pronounced for women than for men and varied regionally. Temporal and regional differences in utilisation were moderately associated with the decrease in mobility in the pandemic year. In the first phase of the pandemic, i.e., March and April 2020, the decline was strongly associated with the regional incidence of SARS-CoV-2 infection. CONCLUSION: Due to the pandemic, significantly fewer rehabilitations due to mental disorders occurred in Germany in 2020 than in 2019. The likely increasing need for rehabilitation for people with mental disorders should be addressed by making rehabilitation access and delivery more flexible.

[Impact of the SARS-CoV-2 Pandemic on the Utilization of Cancer Rehabilitation: a Difference-in-Differences Analysis]. / Auswirkungen der SARS-CoV-2-Pandemie auf die Inanspruchnahme der onkologischen Rehabilitation: eine Difference-in-Differences-Analyse.

PURPOSE: Restricted access to rehabilitative care due to the SARS-CoV-2 pandemic may affect the participation of cancer survivors and risks progression of the underlying disease. The aim of our analyses was to examined the extent to which cancer rehabilitations in Germany decreased due to the SARS-CoV-2 pandemic. METHODS: Data were retrieved from the German Pension Insurance which is the main provider for medical rehabilitation in Germany. We used monthly cross-sectional data on the utilization of cancer rehabilitation (Ca-rehab-services according to section 15 for working-aged people or section 31 social security code VI for pensioners) in 2019 and 2020. We used a difference-in-differences model to determine the reduction in rehabilitation utilization attributable to the pandemic and reported incidence rate ratios (IRR). RESULTS: We included 146,924 cancer rehabilitations in 2019 and 113,117 cancer rehabilitations in 2020. Compared to the previous year, the nationwide decline in cancer rehabilitations was greatest in April 2020 (63.2%). Utilization of cancer rehabilitation was reduced by 11.5% for benefits according to section 15 social security code VI (IRR=0.885; 95% CI: 0.864 to 0.906) and by 26.5% for benefits according to section 31 (IRR=0.735; 95% CI: 0.717 to 0.754) due to the pandemic. For pensioners the decline in utilization was more pronounced in Western Germany than in Eastern Germany and greater for non-post-acute rehabilitations than for post-acute rehabilitations. CONCLUSION: The analyses show a pandemic-related decline in cancer rehabilitations, especially in cancer rehabilitation services for pensioners. Failure to seek medical rehabilitation, through which physical and psychological recovery and relief from disease and treatment side effects can be achieved, will have a lasting impact on the participation for many cancer survivors. Repeated monitoring of work ability and health of chronically ill people could generate necessary data to clarify why people in need of rehabilitation have avoided seeking medical rehabilitation and how they can be supported.

A comprehensive diagnostic service to clarify intervention needs when work participation is at risk: study protocol of a randomized controlled trial (GIBI, DRKS00027577).

BACKGROUND: Effective care services for people whose work participation is at risk require low-threshold access, a comprehensive diagnostic clarification of intervention needs, a connection to the workplace and job demands, and interdisciplinary collaboration between key stakeholders at the interface of rehabilitation and occupational medicine. We have developed a comprehensive diagnostic service to clarify intervention needs for employees with health restrictions and limited work ability: this service is initiated by occupational health physicians. METHODS/DESIGN: Our randomized controlled trial tests the effectiveness of a comprehensive diagnostic service for clarifying intervention needs (GIBI: Comprehensive clarification of the need for intervention for people whose work participation is at risk). The comprehensive intervention comprises three elements: initial consultation, two-day diagnostics at a rehabilitation center and follow-up consultations. We will include 210 employees with health restrictions and limited work ability, who are identified by occupational health physicians. All individuals will receive an initial consultation with their occupational health physician to discuss their health, work ability and job demands. After this, half the individuals are randomly assigned to the intervention group and the other half to the waiting-list control group. Individuals in the intervention group start two-day diagnostics, carried out by a multi-professional rehabilitation team in a rehabilitation center, shortly after the initial consultation. The diagnostics will allow first recommendations for improving work participation. The implementation of these recommendations is supported by an occupational health physician in four follow-up consultations. The control group will receive the comprehensive two-day diagnostic service and subsequent follow-up consultations six months after the initial consultation. The primary outcome of the randomized controlled trial is self-rated work ability assessed using the Work Ability Score (0 to 10 points) six months after study inclusion. Secondary outcomes include a range of patient-reported outcomes regarding physical and mental health, impairment, and the physical and mental demands of jobs. DISCUSSION: This randomized controlled trial is designed to test the effects of a new complex intervention involving a comprehensive clarification of intervention needs in order to promote work participation and prevent the worsening of health and work disability. TRIAL REGISTRATION: German Clinical Trials Register (DRKS00027577, February 01, 2022).

Unemployment due to the SARS-CoV-2-pandemic among people with and without severe disabilities: a difference-in-differences analysis.

OBJECTIVES: Unemployment reduces health and impairs participation in important areas of life, especially for people with severe disabilities, who tend to have a longer duration of unemployment and are less likely to find new employment than their counterparts without such constraints. Our analysis examines the increase in unemployment due to the SARS-CoV-2 pandemic among people with and without severe disabilities in Germany. METHODS: Monthly cross-sectional data on unemployment for 2019 and 2020 were provided by the Federal Employment Agency. We used a difference-in-differences model to estimate the increase in unemployment attributable to the pandemic. The months April to December 2020 represented the months of exposure to the pandemic. Incidence rate ratios (IRRs) are reported. RESULTS: The increase in unemployment among people with severe disabilities due to the pandemic is 11.2% (IRR 1.112; 95% CI 1.107 to 1.117). People with severe disabilities receiving unemployment benefits due to unemployment lasting less than a year (Social Code III: short-term unemployment) and women have been most affected. Among people without severe disabilities, unemployment has increased by 24.8% due to the pandemic (IRR 1.248; 95% CI 1.246 to 1.249), while people receiving unemployment benefits according to social code III and men have been most affected. Both groups show a varying increase in unemployment depending on the region of residency. CONCLUSIONS: The findings show a particularly significant increase in unemployment among people without severe disabilities. People with severe disabilities might be less impacted due to the special legal protection against their dismissal. The clear regional differences in the increase in unemployment suggest a strong influence of regional economics.

Work ability score as predictor of rehabilitation, disability pensions and death? A German cohort study among employees with back pain.

BACKGROUND: Sickness absence, disability pensions, and use of healthcare due to disabling back pain are a high economic burden in Germany. Assessment are needed to identify employees who are likely to need intensive support. OBJECTIVE: The cohort study examined whether rehabilitation, disability pensions and death can be predicted by a simple self-reported rating of work ability in employees with back pain in Germany. METHODS: Employees aged 45 to 59 years who reported back pain in the last 3 months completed the Work Ability Score in 2017 (0-10 points). Individual scores were categorized into poor (0-5 points), moderate (6-7) and at least good (8-10) work ability. Outcomes were extracted from administrative records covering the period until the end of 2018. Proportional hazard models were fitted to determine the prognostic benefit of the Work Ability Score. RESULTS: Data for 6,917 participants were included (57.8% women). The median follow-up time was 20 months. Of the participants, 52.1% had a good or excellent, 27.7% a moderate, and 20.2% a poor Work Ability Score. During follow-up, 548 persons were granted rehabilitation measures, 57 persons disability pensions, and 23 died. Fully adjusted analyses showed an increased risk of a rehabilitation measure (hazard ratio = 2.65; 95% CI 2.11; 3.34) and a disability pension (HR = 4.12; 95% CI 2.02; 8.39) in employees with poor work ability. A premature death was not associated with poor work ability. CONCLUSIONS: The Work Ability Score is a potential tool to identify individuals, reporting back pain, with an increased risk of health-related early retirement and work disability.

Rehabilitation utilization of non-migrant and migrant persons with back pain: A cohort study using different definitions of migrant background.

Background: Medical rehabilitation (MR) by the German Pension Insurance is approved to maintain and to restore work ability and to avoid disability pensions. Studies on the rehabilitation utilization by people with a migration background (PMB) compared to people without a migration background (non-PMB) showed heterogeneous results, which may be partly due to different definitions of migration status. The aim of this paper was to test whether there are differences in utilization of MR between employed PMB and non-PMB with self-reported back pain. Methods: We used data from a large German cohort study that analyzed the effectiveness of MR for individuals with back pain and was conducted between 1st January 2017 and 31st December 2019. Employees aged 45 to 59 years who reported back pain in the last three months completed the baseline questionnaire in 2017. We used four definitions of migration background (MB) to differentiate by first- and second-generation migration, by one- and two-sided migration background, by language, or by nationality. Data on rehabilitation utilization was extracted from administrative records covering the period until the end of 2018. Findings: Data of 6,713 participants were included, and 514 individuals utilized MR during follow-up. Adjusted analyses showed a decreased risk of rehabilitation utilization in people with a first-generation MB (HR = 0·46; 95% CI 0·29; 0·72), people with a two-sided MB (HR = 0·47; 95% CI 0·31; 0·72), people whose native language was not German (HR = 0·52; 95% CI 0·30; 0·91), and people without German nationality (HR = 0·29; 95% CI 0·12; 0·72) when compared to non-PMB. Interpretation: This study showed that employees with a MB reporting back pain had a significantly reduced risk for utilization of rehabilitation services. This underutilization could be observed considering different definitions of MB. Future research on rehabilitation utilization by PMB should consider the impact of different definitions on the results. Funding: The study was funded by the German Research Foundation (grant numbers: BE 5885/2-1; MA 6981/2-1). The German Research Foundation functions as a self-governing institution for the promotion of science and research in Germany.

Barriers to applying for medical rehabilitation: a time-to-event analysis of employees with severe back pain in Germany.

OBJECTIVE: Longitudinal studies on barriers to applying for rehabilitation in Germany are lacking in light of the suspected underutilization of rehabilitation services. The aim of this study was to examine application behaviour in persons with disabling back pain and to identify relevant predictors for making an application. DESIGN: A prospective cohort study with randomized sampling of insurants in the German Pension Insurance, using a questionnaire at baseline and follow-up with linked administrative data for 1.5 years. SUBJECTS/PATIENTS: Employed persons (age range 45-59 years) with a high degree of limitations due to back pain and a self-reported risk of permanent work disability (not applied for disability pension, no medical rehabilitation within the last 4 years). METHODS: Multivariable Cox regression was used to examine the influence of pre-selected variables on making an application in the follow-up period. RESULTS: Of 690 persons, only 12% applied for rehabilitation. Predictors for making an application were: support from physicians (hazard ratio (HR)=2.24; 95% confidence interval (95% CI) 1.32-3.80), family, and friends (HR=1.67; 95% CI 1.02-2.73), more pain-related disability days (HR=1.02; 95% CI 1.01-1.03), and worse work ability (HR=0.86; 95% CI 0.75-0.97). An intention to apply at baseline mediated the effect of family and physician support on the application. CONCLUSION: The low number of applications for rehabilitation despite disabling back pain indicates access barriers to, and underuse of, medical rehabilitation.

Reduced Requests for Medical Rehabilitation Because of the SARS-CoV-2 Pandemic: A Difference-in-Differences Analysis.

OBJECTIVE: To examine the extent to which medical rehabilitation requests decreased because of the pandemic in Germany. DESIGN: Data were retrieved from the German Pension Insurance, which is the main provider for rehabilitation of working-age people in Germany. Our data represented all medical rehabilitation requests in 2019 and 2020. These requests have to be approved to use a rehabilitation program. We used a difference-in-differences model to determine the reduction in rehabilitation requests attributable to the pandemic. SETTING: General community. PARTICIPANTS: We included 1,621,840 rehabilitation requests from working-age people across Germany in 2019 and 1,391,642 rehabilitation requests in 2020 (N=3,013,482). INTERVENTION: Medical rehabilitation in inpatient or outpatient facilities. MAIN OUTCOME MEASURES: Number of medical rehabilitation requests. RESULTS: The number of medical rehabilitation requests decreased by 14.5% because of the pandemic (incidence rate ratio, 0.855; 95% confidence interval, 0.851-0.859). The decline in requests was more pronounced among women and in Western Germany than among men and in Eastern Germany. The reduction in requests affected non-postacute rehabilitations more clearly than postacute rehabilitation services. After the pandemic declaration by the German Bundestag in March 2020, the reduction in requests was initially strongly associated with the regional incidence of infection. This association weakened in the following months. CONCLUSIONS: The reduction in requests will have a significant effect on the number of completed rehabilitation services. For many people with chronic diseases, failure to provide medical rehabilitation increases the risk of disease progression.

Effectiveness of medical rehabilitation in persons with back pain - lessons learned from a German cohort study.

PURPOSE: Evidence for health-related effects of German medical rehabilitation programs for back pain is inconclusive. This cohort study aimed to examine the effectiveness of medical rehabilitation in residents with back pain (German Clinical Trial Register: DRKS00011554). MATERIAL AND METHODS: A sample of 45 000 people aged 45-59 years was randomly drawn from two pension agencies. We used propensity score matching to compare persons with back pain who completed a medical rehabilitation program with similar untreated subjects. Questionnaire data were assessed in 2017 and 2019, and linked with administrative data. The primary outcome was pain disability. RESULTS: In total, 6610 persons with back pain were considered for matching and we finally compared 200 persons treated in a medical rehabilitation program with 200 untreated subjects. Pain disability was reported more favorable in the control group without medical rehabilitation compared to the intervention group (difference = 4.2; 95% CI -0.8-9.2), as well as other secondary outcomes. CONCLUSIONS: At first glance, the findings suggest that medical rehabilitation was ineffective in improving health, pain and work ability among employed persons with back pain, but we found plausible explanations indicating that the estimated effects in favor of the untreated subjects are methodologically induced.IMPLICATIONS FOR REHABILITATIONPropensity score matching can be used to assess the effects of multimodal interventions in persons with back pain in routine care.Inappropriate recruitment of controls may underestimate treatment effects.When using observational data and propensity score matching to analyze the effectiveness of medical rehabilitation, baseline survey should be conducted directly before the start of rehabilitation to identify comparable controls.

Self-Reported Prognosis of Employability as an Indicator of Need for Rehabilitation: A Cohort Study in People with Back Pain.

PURPOSE: Rehabilitation is a key strategy to enable people with disabilities or chronic diseases to participate in society and employment. In Germany, the approval of rehabilitation services is linked to personal requirements, including significantly compromised work ability due to illness. The subjective prognosis of employability (SPE) is a brief 3-item scale. The total score assesses the self-rated risk of permanent work disability and was therefore proposed to be an indicator to operationalize the requirements to determine the need for a medical rehabilitation measure. This cohort study examined whether rehabilitation and disability pensions can be predicted by the SPE in employees with back pain. Moreover, the study tested the applicability of the SPE regarding interrupted employment. METHODS: Employees aged 45 to 59 years who reported back pain in the last three months completed the SPE in 2017. The total score ranges from 0 to 3 points, with higher values indicating a higher risk of permanent work disability. Data on rehabilitation, disability pensions, and interrupted employment were extracted from administrative records covering the period until the end of 2018. Proportional hazard and logistic regression models were fitted. RESULTS: Data of 6,742 participants were included (mean age: 52.3 years; 57.8% women). Maximum follow-up was 21 months. Of the participants, 38.8, 33.6, 21.4, and 6.2% had an SPE score of 0, 1, 2, and 3 points, respectively. During follow-up, 535 individuals were approved for a rehabilitation measure and 49 individuals for a disability pension. Fully adjusted analyses showed an increased risk of a rehabilitation in employees with an SPE score of 3 points (HR=2.20; 95% CI 1.55; 3.11) and 2 points (HR=1.76; 95% CI 1.33; 2.31) compared to employees with an SPE score of 0 points. The risk of a disability pension (HR=13.60; 95% CI 4.56; 40.57) and the odds of interrupted employment (OR=2.58; 95% CI 1.72; 3.86) were also significantly increased for those with an SPE score of 3 points. CONCLUSIONS: The brief SPE is an appropriate tool to identify individuals reporting back pain at risk of rehabilitation, poor work participation outcomes, and permanent work disability. HINTERGRUND: Rehabilitation ist eine Schlüsselstrategie, um Menschen mit Behinderungen oder chronischen Erkrankungen die Teilhabe an der Gesellschaft und am Arbeitsleben zu ermöglichen. In Deutschland ist die Bewilligung von Rehabilitationsleistungen an persönliche Voraussetzungen geknüpft, u. a. an eine erhebliche Gefährdung der Erwerbsfähigkeit aufgrund von Krankheit. Die subjektive Erwerbsprognose (SPE) ist eine kurze 3-Item-Skala. Der Gesamtscore bewertet das selbst eingeschätzte Risiko einer dauerhaften Arbeitsunfähigkeit und wurde daher als Indikator zur Operationalisierung der Voraussetzungen und zur Bestimmung des Bedarfs an einer medizinischen Rehabilitationsmaßnahme vorgeschlagen. Die Kohortenstudie untersucht, inwiefern Rehabilitationen und Erwerbsminderungsrenten durch die SPE bei Beschäftigten mit Rückenschmerzen vorhergesagt werden können. Zudem wurde die Assoziation zwischen der SPE und unterbrochener Beschäftigung getestet. METHODEN: Die SPE wurde im Jahr 2017 bei Versicherten im Alter von 45 bis 59 Jahren, die Rückenschmerzen in den letzten drei Monaten berichteten, erhoben. Der Gesamtscore reicht von 0 bis 3 Punkten, wobei höhere Werte ein höheres Risiko für eine dauerhafte Erwerbsunfähigkeit anzeigen. Daten zu Rehabilitationen, Erwerbsminderungsrenten und unterbrochener Beschäftigung umfassen den Zeitraum bis Ende 2018 und wurden aus den Versichertenkonten extrahiert. Die Zusammenhänge wurden mittels proportionaler Hazard- und logistischer Regressionsmodelle getestet. ERGEBNISSE: Es wurden die Daten von 6.742 Teilnehmenden eingeschlossen (mittleres Alter: 52,3 Jahre; 57,8% weiblich). Der maximale Nachbeobachtungszeitraum betrug 21 Monate. 38,8, 33,6, 21,4 und 6,2% hatten einen SPE-Score von 0, 1, 2 bzw. 3 Punkten. Im Beobachtungszeitraum wurde 535 Personen eine Rehabilitationsmaßnahme und 49 Personen eine Erwerbsminderungsrente bewilligt. Vollständig adjustierte Analysen zeigten ein erhöhtes Risiko für eine Rehabilitation bei Beschäftigten mit einer SPE von 3 Punkten (HR=2,20; 95% KI 1,55; 3,11) und 2 Punkten (HR=1,76; 95% KI 1,33; 2,31) im Vergleich zu Personen mit einer SPE von 0 Punkten. Das Risiko einer Erwerbsminderungsrente (HR=13,60; 95% KI 4,56; 40,57) und die Wahrscheinlichkeit für eine unterbrochene Beschäftigung (OR=2,58; 95% KI 1,72; 3,86) waren ebenfalls signifikant erhöht für diejenigen mit einer SPE von 3 Punkten. SCHLUSSFOLGERUNGEN: Die SPE ist bei Menschen mit selbstberichteten Rückenschmerzen ein geeignetes Assessmentinstrument zur Identifizierung von Personen, bei denen ein erhöhtes Risiko für eine Rehabilitation, gefährdete berufliche Teilhabe und dauerhafte Arbeitsunfähigkeit besteht.
