This study could directly impact quality of care provided to older adults and the success of a national health IT initiative by offering a critically missing component in the current PP implementation process—patient support for the health IT (PP) designed for patients. Findings from the study will also provide hospitals, vendors, and policymakers in-depth information on older adults' current PP usage patterns and other challenges in using various PPs at the national level, contributing to the improvement of PP technology and clinical practices. Once the feasibility of the study is demonstrated, the vendor-agnostic T-PeP could be used widely and incorporated into busy practices. The next R01 study will test its long-term effects on health behavior and clinical outcomes, as well as care cost, using more diverse samples, including practice settings and underserved populations.
