Design outcomes

Primary

Measure	Time frame
The described study is based on the RE-AIM QuEST framework: (1) Reach: Number of participating physiotherapists and patients (2) Effectiveness: Changes in outcome measures at the individual level of the physiotherapists and patients (3) Adoption: Proportion of institutions that actually initiate the GLA:D® program; proportion of trained physiotherapists that actually initiate the GLA:D® program (4) Implementation: Proportion of education and training sessions perceived by patients (5) Maintenance: Proportion of institutions offering the GLA:D® program over a period of 6 months Overview of data sources and primary outcome assessments: (1) Online survey among physiotherapists Physiotherapists attending the two-day education course will be asked to participate in an online survey. The participants will be asked to fill in the same questionnaire after a period of 1-2 weeks after the course and again after 12 months. Data will be collected in the following categories: 1. Demographic and professional information 2. Current care of patients with hip and/or knee osteoarthritis 3. Beliefs about capabilities related to delivering education and exercise therapy to people with hip and/or knee osteoarthritis The third survey (after 12 months) includes an additional section with open-ended questions on barriers and facilitators to the implementation of GLA:D® Germany. The survey results will be used to investigate the effectiveness of the physiotherapists and to describe barriers and facilitators of the implementation of GLA:D® Germany. (2) National GLA:D®-registry To answer questions about the effectiveness of the intervention with regard to the patients, information from the national GLA:D®-registry is used. This includes results from outcome measurements at the beginning of the GLA:D® program as well as after three and 12 months.
