Importance: Geriatric, interprofessional primary care training for occupational therapy students is needed. Objective: To measure occupational therapy student-reported knowledge, attitudes, and skills after participation in interprofessional geriatric educational programs. Design: Prospective, observational study with pre-and posttests for the three programs. Participants: Fifty-nine entry-level and postprofessional occupational therapy master's students. Outcomes and Measures: Self-reported familiarity with other professionals' roles, perceptions of interprofessional training, capabilities to conduct assessments, and attitudes of older adults. Results: Students of the three programs (Interprofessional Geriatrics Curriculum [IPGC], Student Senior Partnership Program [SSPP], and Geriatric Assessment Program [GAP]) reported different improvements in familiarity of roles, capabilities of assessment, and Geriatric Attitudes Scale (GAS) scores. For example, IPGC and SSPP students had changes in total GAS score (3.91-4.08, p = .002, and 3.84-3.99, p = .003, respectively), but no change was found for GAP students (3.85-3.91, p = .523). Conclusions and Relevance: More structured interprofessional education with older adults appeared to help prepare occupational therapy students to work on geriatric interprofessional teams in primary care. What This Article Adds: This article expands on growing evidence to support occupational therapy's role in primary care by addressing the need to train future generations to work on interprofessional geriatric primary care teams. P rimary health care is the accessible frontline service for patients and their families over a lifespan (Institute of Medicine [IOM], 1994). In primary care, disease prevention and management are efficiently managed in the appropriate setting, by the appropriate provider, and in a manner consistent with the patient's values. Because of medical advances and chronic disease management, the geriatric population is projected to reach 98 million by 2060 (Colby & Ortman, 2015). A large group of older adults with a multitude of complex chronic diseases is expected to be managed by primary care teams. Given the shortage of primary care providers, a team-based approach is more essential than ever to improve patient satisfaction and health outcomes and to decrease costs (
