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:
: 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. 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. 297 sites (264 private, 33 public) implemented GLA:D®. Most patients completed at least one education (90%), and 10 exercise-therapy (78%) sessions. Adequate staffing to support program delivery was a key enabler. 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.
