Background: The provision of low-value care services in low back pain management is a problem of global scope. Inappropriate imaging, overmedication, and overused invasive therapies are prevalent in physician services. Yet, little is known about overused low-value physiotherapy services. Most studies addressing physiotherapy overuse in low back pain management arose from countries in which physiotherapy is established in primary care. However, measures and instruments addressing physiotherapy overuse limitedly fit legislative conditions of health systems in which physiotherapy is a service of secondary care. Thus, this scoping review's purpose is to map existing research designs and instruments aiming to detect overused low-value physiotherapy services taking specific healthcare settings and aspects of medical overuse into account.
Methods: The development of this scoping review is guided by the Arksey and O'Malley framework. A two-step, peer-reviewed search strategy in accordance with the PRESS checklist will be conducted on MEDLINE (PubMed), Web of Science, and CINHAL. Additionally, gray literature will be searched on Google Scholar. Preprints of empirical studies will be included. Initially, two reviewers will independently screen articles for eligibility by title and abstract. A third reviewer will mediate discrepancies. Uncertainties will be eliminated by a full-text analysis or by contacting the corresponding authors. A four-step analytical process will guide result reporting focusing on major research questions outlined in this protocol. Numerical and narrative tables, graphics, and narrative summaries will be the methods to summarize and collate results. In the final step, the German health system will serve as an exemplary setting and frame to practically apply results.
Discussion: Results of this scoping review will help researchers to systematically select overuse measures referring to aspects of the overuse typology, specific healthcare settings, and physiotherapy services. It will further provide information on the limitations of present studies and will give advice on how to address them. Moreover, this review will illustrate to what degree existing studies succeed to comprehensively cover the concept of the overuse typology.
Systematic review registration: This protocol has been registered on the open science framework ( https://doi.org/10.17605/OSF.IO/PMF2G ).
