Abstract
OBJECTIVE: Evaluate the implementation of Good Life with osteoArthritis from Denmark (GLA:D®) for knee osteoarthritis in Australia using the RE-AIM QuEST (Reach, Effectiveness, Adoption, Implementation, Maintenance Qualitative Evaluation for Systematic Translation) framework. DESIGN: Physiotherapists completed surveys before and after GLA:D® training (2017-2020) to assess practices, and barriers and enablers to implementation. Patients completed online baseline, 3-month (post-treatment) and 12-month patient reported outcomes. Effective implementation was defined as within-participant moderate effect size (ES, ≥0.50) for average pain (100 mm VAS) and Knee Injury and Osteoarthritis Outcome Score quality of life scores (KOOS-QoL), and small effect size (≥0.20) for health-related quality of life (EQ-5D-5L). RESULTS: Reach : 1064 physiotherapists and 1945 patients from all states and territories participated. Key barriers included out-of-pocket cost to patients, and program suitability for culturally and linguistically diverse communities. Effectiveness: Following training, more physiotherapists reported discussing treatment goals and weight management, and prescribing supervised, neuromuscular exercise. Patient outcomes at 3- and 12-months (n = 1044 [54%] and 927 [48%]) reflected effective implementation, including reduced pain (ES, 95%CI = 0.72, 0.62-0.84; and 0.65, 0.54-0.77) and improved KOOS-QoL (0.79, 0.69-0.90; and 0.93, 0.81-1.04) and EQ-5D-5L (0.43, 0.31-0.54; and 0.46, 0.35-0.58) scores. Adoption: 297 sites (264 private, 33 public) implemented GLA:D®. Implementation: Most patients completed at least one education (90%), and 10 exercise-therapy (78%) sessions. Adequate staffing to support program delivery was a key enabler. Maintenance: 99% of sites (293/297) continued offering the program in July 2020. CONCLUSION: Training changed practice and was associated with effective widespread implementation of GLA:D® in Australia.
