Primary health care is rapidly developing as an occupational therapy practice area. Yet, to date, little evidence supports occupational therapy's feasibility and efficacy in primary care settings.To report on the implementation and preliminary clinical outcomes of a Lifestyle Redesign (LR)-occupational therapy (LR-OT) diabetes management intervention in a primary care clinic.Patients were randomized to be offered LR-OT or to a no-contact comparison group (data not reported). We assessed implementation outcomes using mixed methods.Safety-net primary care clinic.Clinic providers and staff; English- or Spanish-speaking clinic patients ages 18-75 yr with diabetes and a current hemoglobin A1c (HbA1c) ≥ 9.0%.Eight 1-hr individual sessions of LR-OT focused on diabetes management.Clinical and health behavior outcomes were assessed via electronic medical record (EMR) review and self-report surveys of patients receiving LR-OT at initial evaluation and discharge. We assessed implementation outcomes (acceptability, appropriateness, feasibility, fidelity, efficiency, and timeliness) using patient and staff surveys, interviews, focus groups, and observations.Seventy-three patients were offered LR-OT: 51 completed one or more sessions, and 38 completed the program. Clinical outcomes among program completers indicate beneficial changes in HbA1c, diabetes self-care, and health status. Implementation challenges included a need for patient and staff education, securing adequate workspace, and establishing a referral process. Factors contributing to implementation success included strong buy-in from clinic leadership, colocation, and shared EMR documentation.LR-OT is a feasible approach to enhancing service delivery and clinical outcomes in primary care.This study provides insight into factors that may create challenges or contribute to the success of implementing occupational therapy services within primary health care settings. In addition, this study provides preliminary evidence of occupational therapy's effectiveness in improving clinical outcomes among ethnically diverse, low-income patients with diabetes in a safety-net primary care setting.
