Implementing lifestyle-related treatment modalities in osteoarthritis care: Identification of implementation strategies using the Consolidated Framework for Implementation Research-Expert Recommendations for Implementing Change matching tool.

Aims: Despite recommendations in international clinical guidelines, lifestyle-related treatment modalities (LRTMs) are currently underutilised in the conservative treatment of patients with hip and/or knee osteoarthritis. This study aimed to identify implementation strategies in order to address barriers to implementing LRTMs from the perspective of healthcare professionals (HCPs).

Methods: The Consolidated Framework for Implementation Research (CFIR)-Expert Recommendations for Implementing Change (ERIC) Implementation Strategy Matching Tool was applied. First, previously identified influencing factors among primary and secondary HCPs were mapped onto the corresponding CFIR constructs/subconstructs by two researchers. Second, the CFIR-based barriers relevant for all HCPs were entered into the tool. Third, the CFIR-based barriers specific to one or more subgroups of HCPs served as additional input for the tool. Finally, a selection of ERIC implementation strategies was made based on the tool's output.

Results: Fourteen implementation strategies were selected. The strategy most endorsed by the tool was 'build a coalition'. Eight of the selected strategies belonged to the ERIC cluster 'develop stakeholder interrelationships'. Other strategies were part of the clusters 'use evaluative and iterative strategies' (n = 3), 'utilise financial strategies' (n = 2), and 'engage consumers' (n = 1).

Conclusions: The findings emphasise the importance of an interdisciplinary approach when addressing the implementation of LRTMs in osteoarthritis care. The final selection of implementation strategies forms the basis for a tailored implementation plan. Future work should focus on further operationalising the implementation strategies and evaluating the effectiveness of the resulting implementation plan.
