Implementing the Effective Coach2Move Approach for Community-Dwelling Older Adults With Mobility Limitations in Physical Therapist Practice: A Multi-Methods Process Evaluation

Abstract Objective The aims of this study were to evaluate the adoption of and fidelity to the Coach2Move approach; identify differences between physical therapists with a specialization in geriatrics and physical therapists without a specialization; explore if level of adoption and specialization explain variances in effectiveness; and explore group differences in attitudes and experiences with implementation. Methods A multi-methods process evaluation of Coach2Move implementation through 2 education days, 3 peer-assessment meetings, and an adapted electronic health record was performed alongside a cluster randomized stepped-wedge trial comparing regular care physical therapy with Coach2Move. Participants were 36 physical therapists with a specialization (n = 17) and without a specialization (n = 19) who treated 292 community-dwelling older adults. Level of adoption and fidelity were analyzed by comparing preimplementation scores with scores 1 year later. Coach2Move adoption was measured by e-assessment scores, and fidelity through health record indicators. The impact of specialization and adoption on health outcomes was examined using a mixed-model analysis of variance. Therapists’ attitudes and experiences were collected through a survey based on semistructured interviews. Results Mean (SD) total indicator scores on the e-assessment (adoption of a Coach2Move mindset) increased from baseline 17% (5%) to 47% (9%) at follow-up. Physical therapists with a specialization in geriatrics scored (mean [SD]) higher than physical therapists without (54% [6%] vs 41% [6%]). Mean (SD) indicator scores on health records (fidelity) increased from 35% (12%) at baseline to 47% (15%) at follow-up. Mean scores of physical therapists with a specialization in geriatrics were higher. Level of adoption and specialization (yes/no) did not explain the variance in effectiveness. Physical therapists identified important facilitators, including tailored education and peer-assessment meetings, whereas adequate reimbursement for the extra time investment was considered a necessity. Different workflows in practices were perceived as a barrier. Conclusion Implementation led to increased adoption and fidelity of the Coach2Move intervention by physical therapists but shows room for improvement. Attitudes toward the approach and its implementation were positive. Future implementation efforts on adoption could be improved by focusing on a fair compensation structure by third-party payers a
