Patient-Reported Outcomes Following Inpatient Multimodal Treatment Approach in Chronic Pain-Related Rheumatic Diseases

INTRODUCTION: Musculoskeletal disorders may cause chronic pain, which is associated with deterioration in physical well-being, functions, and quality of life. There are worldwide shortfalls in the care that is provided to the affected patients. Holistic, interdisciplinary care is rare. Monomodal therapeutic approaches dominate when health-care resources are scarce. In this study, we test the patient-relevant outcomes of multimodal treatment for rheumatic diseases that are associated with pain and check for remuneration. METHODS: We performed a retrospective data analysis of an inpatient multimodal treatment. The target parameter was the patient perspective, which we assessed by means of Patient-Reported Outcomes (PRO). We applied the Visual Analogue Scale (mental and physical condition), the Heidelberg Short Early Risk Assessment Questionnaire, the Pain Disability Index, and the pain grading according to Kohlmann/Raspe (N = 375 patients). We also investigated compensation for inpatient treatments with and without multimodal treatments. Moreover, we compared Diagnosis-Related Group remuneration with and without complex treatment. RESULTS: After implementing a multimodal treatment, improved mental (mood) status was significantly better (Wilcoxon signed-rank test, P < . 001), despite high levels of pain (Kohlmann/Raspe) reported on admission. Apart from the underlying rheumatic disease, 111 patients also reported chronic back pain, which was improved following the treatment (t test, P < . 001). Subjective impairments associated with pain were significantly lower at the end of the hospital stay (Wilcoxon signed-rank test, P < . 001). Compensation for inpatient treatments with multimodal treatments increased noticeably in German hospitals in 2016 to 2019, while remunerations for monomodal treatments show mixed results. CONCLUSION: PROs regarding mood, pain, and perceived impairments improved following the multimodal complex treatment. Compensation of hospitals should take into account additional performance requirements of holistic treatments, whereby the promotion and further studies of PROs are recommended.
