POS1470-HPR BARRIERS AND FACILITATORS OF A NEW MODEL OF STRATIFIED EXERCISE THERAPY IN KNEE OSTEOARTHRITIS: A QUALITATIVE STUDY

Background: We have developed a model of stratified exercise therapy, in which three knee osteoarthritis (OA) subgroups (i.e., ‘high muscle strength subgroup’, ‘low subgroup’ and ‘obesity subgroup’) can be distinguished provided subgroup-specific intervention. Currently, the (cost-)effectiveness this compared to usual therapy is tested large-scaled randomized controlled trial (OCTOPuS-study [1]). Alongside trial, we performed qualitative study explore perceived barriers facilitators application primary care. Objectives: To care, as by patients, physiotherapists dieticians. Methods: Qualitative data were collected through semi-structured interviews random sample 15 patients (5 from each subgroup), 11 5 dieticians, experimental arm OCTUPuS trial. A thematic analysis was performed. Results: identified 14 themes categories. In general, therapists positive about added value applicability model, although some would prefer more flexibility. Regarding both reported mixed feelings on low number supervised sessions, with perceiving advantageous for stimulating patient’s own responsibility, whereas others hindering an optimally guided treatment. dieticians acknowledged combined intervention, but disappointed lack interdisciplinary collaboration. Moreover, those subgroup already following diet restriction, therefore not any Conclusion: This revealed relevant our new will help us interpreting upcoming results its (cost-) effectiveness [1]. If proven (cost-)effective, implementation strategies should specifically focus guidance within only few collaboration between physiotherapist dietician adequate use booster sessions after period optimize treatment adherence.
