Purpose: Occupational rehabilitation is an essential part of supporting return to work by the statutory pension insurance institutes. It is useful if health-related restrictions threaten the ability to work. There are various forms of occupational rehabilitation which differ considerably in terms of content, structure, duration, intensity of care and costs. The aim of the study was to identify personal characteristics that can influence the use of three different occupational rehabilitation measures., Methods: All rehabilitants who underwent an occupational rehabilitation in the cooperating occupational rehabilitation centre (Berufsförderungswerk) from 2009 to 2014 under the funding of the German Federal Pension Fund were included in the analysis. A multinomial logistic regression was calculated in order to obtain information on the predictors of utilization of three occupational rehabilitation measures (integration measure, partial qualification, full training). As potential influencing factors, various sociodemographic characteristics as well as various parameters that reflect the employment status of rehabilitants in the previous year were included in the model., Results: The analyses included a total of 934 rehabilitants who had completed an integration measure (n=443), partial qualification (n=315) or full training (n=176). In the final logistic regression model, gender (p<0.0001), age (p<0.0001), education level (p=0.0033), driving license (p<0.0001), willingness to move (p=0.0012), recognized disability (p=0.0404) and the employment status in the third month before the start of the measure (p=0.0020) proved to be significant predictors of utilization., Conclusion: The utilization of the different occupational rehabilitation measures is determined by various influencing factors. In particular, the more extensive and cost-intensive full training are more likely to be taken up by younger, male and more highly qualified rehabilitants., Competing Interests: Die Autoren geben an, dass einer der sieben Autoren im Zeitraum der Datenerhebung im kooperierenden Berufsförderungswerk tätig war.

Background: Early retirements make up a large portion of indirect costs of illness caused by chronic back pain., Methods: Claims data from statutory health insurance and German Pension Fund provide the basis for analysis. Cox-Regression was performed for duration to early retirement, whereby beside sociodemographic and treatment characteristics, the effect of rehabilitation was considered., Results: Early retirement started on average 7.1 month later through rehabilitation. Therefore, rehabilitants made € 8,432.60 higher payments to statutory health insurance and German Pension Fund per rehabilitant. Based on the total number of 21,262 early retirees with orthopedic indications, this can save € 180.7 million. The timing of the early retirement was also affected by age and sickness benefits in the previous month. Savings by avoiding entry into early retirement have not yet been taken into account in this model., Conclusion: Rehabilitants receive later pensions due to reduced ability, which allow for more contributions to statutory health insurance and German Pension Fund. This indicates that medical rehabilitation is an economic and effective treatment., Competing Interests: Prof. Dr. med. Gert Krischak ist an der Moor-Heilbad Buchau gGmbH beschäftigt. Dr. biol. hum.

Background: Chronic back pain is the most common indication in medical rehabilitation. Numerous studies hint on positive effects of rehabilitation on health state. However, there is no evidence about the effectiveness of rehabilitation due to the lack of a valid comparison group., Methods: Based on combined secondary data from German Pension Fund and statutory health insurance, a comparison group of insured persons was identified by their typical patient career that did not apply for rehabilitation for unclear reasons. Effectiveness was measured by direct and indirect costs of back pain between rehabilitants and non-rehabilitants., Results: Costs of rehabilitation split in 2.742 € direct costs and 2.597 € indirect costs. In the 2 years following rehabilitation, rehabilitants were hospitalized less frequent and caused less indirect costs due to disability. Therefore, the benefit of rehabilitation was 727 € in the first year after rehabilitation and additional 37 € in the subsequent year., Conclusion: Rehabilitation for chronic back pain contributes to maintain the ability to work. Moreover, rehabilitation reduces duration of disability and healthcare utilization, hence direct and indirect costs of illness are lowered compared to a treatment without rehabilitation. Effects of rehabilitation by avoidance and delay of retirement are not yet recorded., Competing Interests: Prof. Dr. med. Gert Krischak ist an der Moor-Heilbad Buchau gGmbH beschäftigt.

Objective: The aim of this study was to examine which factors predict rehabilitation setting (inpatient vs. outpatient) after hospitalization in order to indicate the meaning of severity for access to a certain kind of rehabilitation., Methods: All patients with surgery for hip or knee (joint) endoprosthesis or disc surgery between 2005 and 2010 were selected for analysis from anonymized data from statutory health insurance (AOK Baden-Württemberg) and German Pension Fund (Bund as well as Baden-Württemberg). Logistic regression was performed for outpatient vs. inpatient rehabilitation., Results: Patients from all surgery groups utilize more often inpatient rehabilitation, if they started treatment immediately after hospitalization than patients that start treatment after a period at home. With increasing age as well as comorbidities patients use more inpatient rehabilitation. The probability for inpatient rehabilitation decreased between 2005 and 2009., Conclusion: Beneath severity also context factors seem to be issues for the choice of inpatient or outpatient rehabilitation. For a demand-orientated access to a certain kind of rehabilitation, environmental conditions like support by family or accessibility to therapeutic, nursing or medical assistance and medical parameters like severity should be weighed against each other., Competing Interests: Die Autoren geben an, dass kein Interessenkonflikt besteht., (© Georg Thieme Verlag KG Stuttgart · New York.)

Background: After total hip and knee arthroplasty, patients have different options of subsequent treatment: an early postoperative rehabilitation, with or without a period at home, or only outpatient services. The aim of this study was to identify factors predicting the utilization of an early postoperative rehabilitation., Methods: This cross-sectoral analysis is based on claims data of AOK Baden-Württemberg (Statutory Health Insurance), Deutsche Rentenversicherung Bund and Deutsche Rentenversicherung Baden-Württemberg (German Pension Insurance). Predictors for participation in an early postoperative rehabilitation and for an interim period were determined using logistic regression analysis., Results: 82.6% of 9 232 patients were going to an early postoperative rehabilitation after total hip arthroplasty. After total knee arthroplasty, 83.9% of 7 656 patients were utilizing postoperative rehabilitation. Moreover, there was less utilization of postoperative rehabilitation in young, male and foreign patients. The analysis shows that the utilization of post-acute rehabilitation was significantly predicted by sociodemographic variables (age, sex, nationality) as well as comorbidity, outpatient treatment and medication., Conclusion: The results provide an indication of higher severity of patients in group "postoperative rehabilitation without a period at home". Nevertheless there are some indications for under-utilization of certain patient groups., Competing Interests: Die Autoren geben an, dass kein Interessenkonflikt besteht., (© Georg Thieme Verlag KG Stuttgart · New York.)

Objective: The aim of this study was a comparison of treatment results in the year after disk surgery between the following treatment groups: rehabilitation immediately after discharge from hospital, rehabilitation with a transition time (at home) up to twenty days after rehabilitation or no rehabilitation., Methods: On basis of claims data from a statutory health insurance and the German Federal Pension Fund the comparison of treatment results was performed. Therefore, duration of disability, return to work and early retirement are considered as treatment results and are analyzed using general linear models (GLM). Furthermore utilization of occupational rehabilitation was compared between the treatment groups with logistic regression., Results: Rehabilitants showed a lower risk of unemployment. Moreover, rehabilitants utilize more often occupational rehabilitation. Both rehabilitation treatment groups had a higher duration of disability (including duration of rehabilitation) in the first quarter after surgery. Afterwards the duration of disability decreased faster. Risk of early retirement was higher in patients that started rehabilitation immediately., Conclusion: Rehabilitants tend to have better treatment results in the year following disc surgery., Competing Interests: Die Autoren geben an, dass kein Interessenkonflikt besteht., (© Georg Thieme Verlag KG Stuttgart · New York.)

The aim of this study was to identify relevant factors that influence utilization and interim period between hospitalization and postoperative rehabilitation after disk surgery. Logistic regression was performed for utilization of an early postoperative rehabilitation and for an interim period, when patients were going to a rehabilitation facility (directly after hospitalization or after a period at home) on claims data from statutory pension insurance and statutory health insurance. Increased utilization of postoperative rehabilitation was found in older and German patients. Moreover, adiposity and additional physiotherapy in hospital increased the utilization of postoperative rehabilitation, while blood transfusion during hospitalization was an inhibiting factor.Female gender, older age and additional physiotherapy in hospital decreased the probability for an interim period between hospitalization and postoperative rehabilitation. However, the probability for an interim period increased from 2005 to 2010. Utilization and interim period between hospitalization and postoperative rehabilitation meet patient's needs and seem adequate. Nevertheless, there are indications for under-utilization of certain patient groups (foreign citizens, unemployed persons, male patients)., Competing Interests: Interessenkonflikt: Die Autoren geben an, dass kein Interessenkonflikt besteht., (© Georg Thieme Verlag KG Stuttgart · New York.)

Study Objectives: The aim was to investigate the predictive value of the employment status measured in the 6 th , 12 th , 18 th and 24 th month after medical rehabilitation for long-term employment trajectories during 4 years. Methods: A retrospective study was conducted based on a 20%-sample of all patients receiving inpatient rehabilitation funded by the German pension fund. Patients aged <62 years who were treated due to musculoskeletal, cardiovascular or psychosomatic disorders during the years 2002-2005 were included and followed for 4 consecutive years. The predictive value of the employment status in 4 predefined months after discharge (6 th , 12 th , 18 th and 24 th month), for the total number of months in employment in 4 years following rehabilitative treatment was analyzed using multiple linear regression. Per time point, separate regression analyses were conducted, including the employment status (employed vs. unemployed) at the respective point in time as explanatory variable, besides a standard set of additional prognostic variables. Results: A total of 252 591 patients were eligible for study inclusion. The level of explained variance of the regression models increased with the point in time used to measure the employment status, included as explanatory variable. Overall the R²-measure increased by 30% from the regression model that included the employment status in the 6 th month (R²=0.60) to the model that included the work status in the 24 th month (R²=0.78). Conclusion: The degree of accuracy in the prognosis of long-term employment biographies increases with the point in time used to measure employment in the first 2 years following rehabilitation. These findings should be taken into consideration for the predefinition of time points used to measure the employment status in future studies., (© Georg Thieme Verlag KG Stuttgart · New York.)

Aim of the Study The outcome quality of medical rehabilitation is evaluated often by "Patient Reported Outcomes" (PROs). It is examined to what extent these PROs are corresponding with "hard" or "objective" outcomes such as payments of contributions to social insurance. Methods The "rehabilitation QM outcome study" includes self-reports of patients as well as data from the Rehabilitation Statistics Database (RSD) of the German pension insurance Baden-Wurttemberg. The sample for the question posed includes N=2 947 insured who were treated in 2011 in 21 clinics of the "health quality network" and who were either employed or unemployed at the time of the rehabilitation application (e. g. the workforce or labour force group, response rate: 55%). The sample turned out widely representative for the population of the insured persons. Results PROs and payment of contributions to pension insurance clearly correspond. In the year after the rehabilitation improved vs. not improved rehabilitees differed clearly with regard to their payments of contributions. Conclusions The results support the validity of PROs. For a comprehensive depiction of the outcome quality of rehabilitation PROs and payments of contributions should be considered supplementary., (© Georg Thieme Verlag KG Stuttgart · New York.)

To ascertain the current development of the rehabilitation-related medical teaching in the interdisciplinary subject Rehabilitation, Physical Medicine, Naturopathic Treatment (Q12) regarding its execution, content, exams and evaluation of teaching at the Medical Faculties the German Society of Rehabilitation Science conducted another faculty survey in 2015. Representatives of all degree courses of human medicine in German Universities (n=41) received a pseudonymised standardised questionnaire in summer 2015. The response rate was 76% (n=31). Half of the faculties (48%) stated that they had a teaching and research unit for at least 1 of the 3 subjects of the interdisciplinary Q12. The Q12-teaching of faculties including these units partially differed from the other faculties. Model medical education programmes provide on average 2 semesters more for Q12-teaching in comparison to the traditional programmes. More than 3 quarters of the traditional programmes and all other courses include other medical professionals besides physicians as lecturers. Multiple choice questions still constitute the most common examination type (94%). Nearly all Medical Faculties evaluate the rehabilitation-related teaching but only half of all them have implemented a financial gratification based on the evaluation results. Even 10 years after the implementation of Q12, major variations were demonstrated regarding the execution, content and methods of medical education in rehabilitation. In the future the influence of the National Competence Based Catalogues of Learning Objectives for Undergraduate Medical Education on the Q12-development and the Q12-teaching in medical university education in Germany with foreign qualification will be of particular interest., (© Georg Thieme Verlag KG Stuttgart · New York.)

Objective: Effects of a combined orthopedic and psychosomatic rehabilitation (VOP) concept are evaluated in contrast to psychosomatic and orthopedic rehabilitation. Therefore both mental and physical health of rehabilitants are compared. Methods: A prospective case-control study was performed in order to gather psychic strain and bodily constitution. Covariance analysis was conducted to expose significant differences between groups. Results: An equal clinically relevant reduction of psychological distress could be achieved with psychosomatic rehabilitation (N=322) and VOP (N=511). Moreover, bodily constitution could be increased by the same amount through VOP and orthopedic rehabilitation (N=135). In conclusion the therapy concept is successful in patients with both somatic and psychic problems., (© Georg Thieme Verlag KG Stuttgart · New York.)

Background: The first step to initiate a stepwise occupational reintegration (SOR) is the recommendation of the rehabilitation centers. Therefore rehabilitation centers have a significant impact on the use of SOR. There is evidence that the recommendation rate between the rehabilitation centers differs clearly. The present survey therefore analyses in detail the differences of the recommendation rate and examines which patient-related factors could explain the differences., Methods: This study is based on analysis of routine data provided by the German pension insurance in Baden-Württemberg (Rehabilitationsstatistikdatenbasis 2013; RSD). In the analyses rehabilitation measures were included if they were conducted by employed patients (18-64 years) with a muscular-skeletal system disease or a disorder of the connective tissue. Logistic regression models were performed to explain the differences in the recommendation rate of the rehabilitation centers., Results: The data of 134 853 rehabilitation measures out of 32 rehabilitation centers were available. The recommendation rate differed between the rehabilitation centers from 1.36-18.53%. The logistic regression analysis showed that the period of working incapacity 12 month before the rehabilitation and the working capacity on the current job were the most important predictors for the recommendation of a SOR by the rehabilitation centers. Also the rehabilitation centers themselves have an important influence., Discussion: The results of this survey indicate that the characteristic of the patients is an important factor for the recommendation of SOR. Additionally the rehabilitation centers themselves have an influence on the recommendation of SOR. The results point to the fact that the rehabilitation centers use different criteria by making a recommendation., (© Georg Thieme Verlag KG Stuttgart · New York.)

Introduction: An extensive user survey was conducted in the context of updating the Classification of Therapeutic Procedures (KTL 2015). This paper reflects the results of the user survey and raises critical discussion points., Methods: The user survey was sent to all rehabilitation centers contracted by the German pension insurance as well as professional associations. The user survey was available both as a paper questionnaire and as an online version. The feedback of the user survey provided an important basis for the revision of the KTL., Result: The survey yielded 1,868 suggestions from 360 users. Most of them related to chapters E ("occupational therapy, work therapy, other functional therapy") and C ("information, motivation, training"). The change from German diplomas to the international Bachelor's and Master's degrees, and the inclusion of diagnostic and work-related procedures were the main focus of the user feedback., Conclusion: For the revision of the KTL, the user survey provided valuable information. Only by the inclusion of practitioners can the KTL meet the requirements of realistic and comprehensive acquisition of data on therapeutic procedures also in future., (© Georg Thieme Verlag KG Stuttgart · New York.)

In the rehabilitation related teaching as in other subjects of the medical training multiple choice (MC) examinations are the most frequent type of examinations. Compared to other subjects only a few MC questions are available for the interdisciplinary subject Rehabilitation. Therefore an internet-based online platform "Pool of rehabilitation related MC questions" was developed to assist teachers regarding the provision, design and organization of high-quality rehabilitation related MC questions. A total of 502 existing MC questions were collected from 12 German Medical Faculties. After removal of 59 questions not suitable for formal and content reasons a total of 443 questions were presented to 6 reviewers for triple reviews (a total of 1 329 expert reviews received). Of the 502 questions 335 (67%) were included in the final pool including short cases with 46 case studies. The questions refer to the following learning objectives: principles of rehabilitation (40%), rehabilitative interventions (20%), diagnosis and assessment (18%), initiation and control of the rehabilitation process (12%) and methods/quality of rehabilitative interventions (10%). The use of the online platform modules resp. the questions are for free for lecturers. This includes the compilation and output of complete examinations, the statistical evaluation, and other audit-related materials. This examination pool counteracts the current lack of quality-assured rehabilitation-related MC questions and contributes to set common standards for the Medical Faculties to rehabilitation related examinations., (© Georg Thieme Verlag KG Stuttgart · New York.)
