The effects of exercise therapy feedback on subjective treatment outcome and patient satisfaction: study protocol for a mono-centric, randomized, controlled trial in orthopedic rehabilitation (FeedYou)

BACKGROUND

The disease burden of musculoskeletal disorders necessitates multidisciplinary and patient-centered models of care. Exercise therapy represents a first-line treatment strategy and a central component of medical rehabilitation. In order to realize the goals of long-term physical activity and participation as proposed by the ICF, exercise therapy can be supplemented by interventional techniques from the field of psychotherapy. Although psychotherapist feedback has been shown to improve therapeutic outcome and patient satisfaction, feedback use in exercise therapy is mostly limited to motor learning and exercise instruction. The present paper therefore describes the use of multidimensional exercise therapy feedback in medical rehabilitation. The aims of the trial presented in this study protocol are to evaluate the effects of this novel feedback approach on rehabilitation outcomes in comparison to usual care.

METHODS

The study is designed as a prospective, mono-centric, randomized controlled, superiority trial (RCT) with two parallel groups and three measuring points: T0 = start of three-week inpatient rehabilitation, T1 = end of three-week inpatient rehabilitation, T2 = 12-week follow-up. In total, 132 patients suffering from chronic neck, shoulder and/or lumbar spine disorders will be recruited. The intervention involves multidimensional exercise therapy feedbacks during the initial and final physical therapist examination, as well as short exercise therapy feedbacks during the course units of the mandatory group-based exercise therapy program. Primary outcomes are the subjective treatment outcome, assessed by BPI and indication-specific questionnaires, as well as patient satisfaction, assessed by ZUF-8 and an intervention-specific questionnaire. The final data collection is expected by May 2023.

DISCUSSION

This study may provide a valuable insight into the effectiveness of multidimensional exercise therapy feedback to improve treatment outcomes and patient satisfaction in medical rehabilitation. This could contribute to rehabilitation quality assurance and the long-term physical activity behavior of rehabilitation patients. Trial registration The trial has been registered with the German Clinical Trial Register (DRKS) under the Registration Number DRKS00027263.

[Quality-oriented facility selection in the rehabilitation of the German pension insurance]

According to Sixth Book of the Social Code (SGB VI), the German Pension Insurance (GPI) has the mandate to maintain or restore the employability of its insured persons. In order to achieve this goal, the GPI offers its insurees rehabilitation benefits. These are, on the one hand, services for prevention and medical rehabilitation (rehab) and, on the other hand, services for return-to-work or stay-at-work, respectively. In order to fulfill this mandate in the best possible way, in 1990 the GPI introduced instruments of external quality assurance (EQS) with scientific support. The system was firmly established in 1997. Since then, all rehab facilities owned and managed by the GPI are obliged to participate in the EQS system.Over the years, a large number of instruments and procedures have been developed that can map various aspects of quality as structure, process, and outcome. Until 2017, results of the EQS had no influence on the cooperation between the GPI and service providers. With the binding decision of the Federal Executive Board of the GPI in 2017, for the first time the GPI linked the allocation of rehab services for specific patients with the results of EQS. On this basis - confirmed by article 3 of the Digital Pension Overview Act - new paths are being taken. As part of the technically supported selection of a suitable facility for insured persons, quality should systematically and transparently acquire special importance and be consistently taken into account when occupying rehab facilities.This article gives an overview of the development of the proved and tested instruments of rehab quality assurance (QA), their current application, and an outlook on the rehab QA of the future.

[Questionnaire to Assess the Work-Related Orientation of Medical Rehabilitation from the Perspective of the Rehabilitants (WMR-R): Cross-Sectional Study Comparing the Short and Long Versions]

BACKGROUND

The user perception of the work-related treatment is of great importance for the further development and success of work-related medical rehabilitation (WMR). The German Pension Insurance Fund (Deutsche Rentenversicherung DRV Bund) has therefore supported the development of the questionnaire WMR-R that can be used to assess the quality of the structure, process and results of work-related rehabilitation treatment from the patient's point of view. This paper presents a short version and compares it with the long version.

METHODS

Based on a representative sample stratified by indication, employed rehabilitants up to the age of 65 were randomly selected to be questioned 6 months after their rehabilitation with a long version (N=28276) or a short version (N=6611) of WMR-R. In addition, routine data of the German Pension Insurance Fund were included. 27 items each of the long version and 8 items of the short version are added up to a total score and compared with regard to test statistical quality criteria and sample sensitivity.

RESULTS

Participation rates were slightly higher in the short version (31%, N=2115) than in the long version (28%, N=8019). The processing quality in both versions is comparable. The short and long versions correlate with each other at r=0.96 (p<0.01). Both versions have similar validity characteristics and separate well between WMR and standard rehabilitation. Both versions are robust to demographic, disease-related and socio-medical risk factors. Rehabilitants with addiction and psychosomatic as well as neurological diseases rate their rehabilitation as significantly more work-oriented compared to other indications, especially pneumology.

DISCUSSION

Due to the low survey effort and the simple evaluation and interpretation, the short version is particularly suitable for routine surveys of WMR care quality. The long version allows a differentiated recording of the WMR offer of rehabilitation facilities in the sense of strength/weakness analyses.

Quality management in medical rehabilitative care by the German statutory pension insurance scheme

This paper aims to provide an insight into the quality management approach for medical rehabilitation services of the German statutory pension insurance scheme. In the 1990s, the German statutory pension insurance scheme initiated a quality management programme in rehabilitation, which is subject to continuous development. The main objective of implementing quality management in rehabilitative care was quality control and quality improvement. To achieve these goals, five main tools for quality measurements were applied: a classification of therapeutic services, standards of rehabilitative interventions, patient surveys, peer review, and surveys that address structure of care. These tools enable the assessment of the structural and process quality of rehabilitative care, as well as aspects of rehabilitation outcome. As a result, quality of rehabilitation care becomes more measurable, transparent, and hence can be improved on well-founded grounds. These measurements allow implementing comparisons and benchmarking of rehabilitation facilities, thereby creating incentives for quality improvements. Therefore, the development and implementation of quality management measures in facilities of inpatient and outpatient medical rehabilitation is an ongoing process and expands to other areas of rehabilitation.

Agreement between pre-post measures of change and transition ratings as well as then-tests

Background

Different approaches have been developed for measuring change. Direct measurement of change (transition ratings) requires asking a patient directly about his judgment about the change he has experienced (reported change). With indirect measures of change, the patients’ status is assessed at different time points and differences between them are calculated (measured change). When using the quasi-indirect approach (‘then-test’), patients are asked after an intervention to rate their statuses both before the intervention as well as at the time of the enquiry. Associations previous studies have found between the different approaches might be biased because transition ratings are generally assessed using a single, general item, while indirect measures of change are generally based on multi-item scales. We aimed to quantify the agreement between indirect and direct as well as indirect and quasi-indirect measures of change while using multi-item scales exclusively. We explored possible reasons for non-agreement (present-state bias, recall bias).

Methods

We re-analysed a data set originally collected to investigate the prognostic validity of different approaches of change measurements. Patients from a 3-week inpatient rehabilitation programme for either cardiac or musculoskeletal disorders filled in health-status questionnaires (which included scales for sleep function, physical function, and somatisation) both at admission and at discharge. The patients were then randomised to receive either an additional transition-rating or then-test questionnaire at discharge.

Results

Out of 426 patients, 395 (92.7%) completed all questionnaires. Correlation coefficients between indirect and quasi-indirect measures of change ranged from r = .60 to r = .71, compared to r = .37 to r = .48 between indirect and direct measures of change. Correlation coefficients between pre-test and retrospective pre-test (then-test) results ranged from r = .69 to r = .82, indicating a low level of recall bias. Pre-test variation accounted for a substantial amount of variance in transition ratings in addition to the post-test scores, indicating a low level of present-state bias.

Conclusions

Indirect and quasi-indirect measurements of change yielded comparable results indicating that recall bias does not necessarily affect quasi-indirect measurement of change. Quasi-indirect measurement might serve as a substitute for pre-post measurement under conditions still to be specified. Transition ratings reflect different aspects of change than indirect and quasi-indirect methods do, but are not necessarily biased by patients’ present states.

[Cardiac rehabilitation in Germany: a successful model with promising prospects]

Over the past 20 years the German Pension Insurance has rehabilitated nearly 800,000 patients with coronary heart disease. In particular, phase-II rehabilitation has been established as an integral part of cardiac patient care. However, the decreasing number of participants in phase-III must be seen critically. Today's cardiac rehabilitation is characterised by evidence-based treatment modules and a sophisticated quality assurance system that ensures quality orientation in all aspects, from access to rehabilitation through to aftercare. Future developments such as vocationally-oriented medical rehabilitation and the use of new technologies will further improve cardiac rehabilitation. Positive patient feedback and scientific evidence of the effectiveness of cardiac rehabilitation are further incentives to maintain this forward-looking approach.
