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.

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.

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.

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.

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.

The role of different nephrology experts in informed shared decision-making for renal replacement therapy.

BACKGROUND: Interprofessional teams and peer support are being increasingly considered in informed shared decision-making. In Germany, there appear to be deficits in the implementation of informed shared decision-making in the choice of renal replacement therapy, such as the lack of collaboration in interprofessional teams and the absence of structured peer support programmes for patients with chronic kidney disease. OBJECTIVE: To explore nephrologists' and nurses' perspectives regarding their involvement in shared decision-making when choosing renal replacement therapy. DESIGN: Guideline-based, problem-centred interviews were used. PARTICIPANTS: A total of 20 nephrologists and 15 nurses were recruited from 21 dialysis units all over Germany. APPROACH: Interviews were audio-recorded and transcribed. They were analysed thematically using structuring and summary content analysis, supported by the qualitative data analysis software MAXQDA 12. RESULTS: The most important findings were the late or missing participation of nurses in the informed shared decision-making process and the unstructured peer support. Along with time and financial factors, these aspects were seen as barriers to shared decision-making with patients who are often overwhelmed by the diagnosis. Furthermore, informed shared decision-making has been insufficiently considered in professional education and training. CONCLUSION: Shared decision-making in the choice of renal replacement therapy is particularly challenging due to the patients' high disease burden. The greater incorporation of informed shared decision-making in education and training as well as the consistent involvement of nursing staff and structured peer counselling already in the predialysis phase with adequate reimbursement can address the identified hurdles.

RENaBack: low back pain patients in rehabilitation-study protocol for a multicenter, randomized controlled trial.

BACKGROUND: Millions of people in Germany suffer from chronic pain, in which course and intensity are multifactorial. Besides physical injuries, certain psychosocial risk factors are involved in the disease process. The national health care guidelines for the diagnosis and treatment of non-specific low back pain recommend the screening of psychosocial risk factors as early as possible, to be able to adapt the therapy to patient needs (e.g., unimodal or multimodal). However, such a procedure has been difficult to implement in practice and has not yet been integrated into the rehabilitation care structures across the country. METHODS: The aim of this study is to implement an individualized therapy and aftercare program within the rehabilitation offer of the German Pension Insurance in the area of orthopedics and to examine its success and sustainability in comparison to the previous standard aftercare program. The study is a multicenter randomized controlled trial including 1204 patients from six orthopedic rehabilitation clinics. A 2:1 allocation ratio to intervention (individualized and home-based rehabilitation aftercare) versus the control group (regular outpatient rehabilitation aftercare) is set. Upon admission to the rehabilitation clinic, participants in the intervention group will be screened according to their psychosocial risk profile. They could then receive either unimodal or multimodal, together with an individualized training program. The program is instructed in the clinic (approximately 3 weeks) and will continue independently at home afterwards for 3 months. The success of the program is examined by means of a total of four surveys. The co-primary outcomes are the Characteristic Pain Intensity and Disability Score assessed by the German version of the Chronic Pain Grade questionnaire (CPG). DISCUSSION: An improvement in terms of pain, work ability, patient compliance, and acceptance in our intervention program compared to the standard aftercare is expected. The study contributes to provide individualized care also to patients living far away from clinical centers. TRIAL REGISTRATION: DRKS, DRKS00020373 . Registered on 15 April 2020.

[Determinants of the Wish for Rehabilitation and the Intention to Apply in Persons with Back Pain]. / Determinanten des subjektiven Rehabilitationsbedürfnisses und der Antragsintention bei Personen mit Rückenschmerzen.

PURPOSE: Up to now, the main focus of analysis has been on determinants of the application for and utilization of medical rehabilitation due to back pain. The prevalence and determinants of motivational and volitional preceding stages of the application have not yet been well examined. Therefore, this study analyses the prevalence and determinants of the wish for rehabilitation and the intention to apply. METHODS: Data were derived from the baseline survey of a cohort study including a sample of 45,000 persons randomly drawn from the statutory pension agencies (GPI North and GPI Central Germany). The baseline data of persons aged 45-59 years with back pain within the past 3 months, neither receiving disability pension nor medical rehabilitation during the past 4 years were analysed. Determinants of the wish for rehabilitation and the intention to apply were identified using multivariate logistic regression analyses. RESULTS: 2,348 of the 6,549 persons with back pain (36%) wished to participate in a rehabilitation program. Of these 774 (33%) declared their intention to apply. Both dependent variables were strongly associated with the social support by family and friends. The wish for rehabilitation was also strongly determined by the previous experience with rehabilitation services. Another important determinant of the intention to apply was the support by physicians and therapists. Other factors were found to influence both dependent variables differently. CONCLUSION: In order to improve the need-based access to rehabilitation, the preceding stages (wish for rehabilitation and intention to apply) and their partly different determinants should be considered. The support by family and friends as well as physicians and therapists are important. This is a further indication that information and the involvement of these actors are key elements to ensure an acquired access to rehabilitation.

Employability and intention to apply for rehabilitation in people with back pain: A cross-sectional cohort study.

OBJECTIVES: To analyse the association between self-reported prognosis of employability and health-related measures, and to clarify which determinants influence the intention to apply for medical rehabil-itation. DESIGN: Cross-sectional study of a random sample of German employees. PARTICIPANTS: A total of 6,654 participants (58% female) aged 45-59 years with back pain during the last 3 months. RESULTS: Out of a total of 6,654 persons, 4,838 had a positive self-reported prognosis of employability. Persons with positive and negative prognoses clearly differ with regard to health-related measures. Of 1,816 persons who reported a negative prognosis, 26% stated an intention to apply for rehabilitation. Intention was determined mainly by perceived social support from family and friends (odds ratio (OR) 1.87; 95% confidence interval (95% CI) 1.66-2.10), as well as physicians and therapists (OR 1.64; 95% CI 1.41-1.90). CONCLUSION: A negative self-reported prognosis of employability is associated with self-reported health restrictions that may determine the need for rehabilitation interventions. A considerable proportion of persons with self-reported health restrictions do not plan to use medical rehabilitation. Perceived social support is an important facilitator of intention to apply for rehabilitation. However, this study needs to be replicated in other populations combining self-reported and administrative data.
