Tech Enabled Functional Health: Bridging Primary Care Gaps for Older Latinos With Functional Disabilities in Underserved Communities

Functional disabilities (FDs), defined as difficulties in performing daily activities, constitute a significant public health problem associated with increased dependency, poor health outcomes, diminished quality of life, institutionalization, and premature death. Older Latinos residing in Puerto Rico (PR) are disproportionately affected by FDs, with one of the highest rates of FDs (58%) in the US and its territories. Research has demonstrated positive outcomes from employing assistive technology (AT) devices, such as jar openers, sock aids, and canes, among older adults with FDs, thereby enhancing their functioning, participation, and capacity to remain at home or in the community for a longer period. However, Latinos are among the least likely to utilize AT. Given the dearth of culturally competent assistive technology interventions for Latinos, along with the scarcity of rehabilitation professionals and assistive technology services in primary healthcare facilities, this project leverages preliminary data from a prior study that assessed the feasibility of the Viviendo las Ventajas de la Asistencia Tecnológica; (VIVE-AT for short; Living the Advantages of Assistive Technologies) intervention. The specific aims of this project are to:

1. refine the protocol of the VIVE-AT to align with the unique needs of the primary health care clinic;
2. assess the efficacy of the VIVE-AT in comparison to a waitlist control arm, in decreasing FDs and improving the quality of life among Latinos aged ≥65 years post-intervention and at six months;
3. evaluate whether proposed mechanisms of change in FDs, specifically knowledge of AT, motivation for using AT, self-efficacy for using AT, and use of AT, account for the reduction in FDs post-intervention.

To achieve these aims, the interdisciplinary team of this project will first refine the intervention based on recommendations from participants in the feasibility study, as well as input from the Community Advisory Board and older Latinos with FDs through iterative focus groups (Aim 1). Subsequently, 76 older Latinos with physical FDs recruited from a primary health care facility serving low-income communities in PR will be randomly assigned to either the VIVE-AT intervention group (n=38) or a waitlist + attention calls controlled condition group (n=38) to assess its efficacy and mechanisms of change (Aims 2 and; 3). All participants will receive standard usual care at the primary health care center. Participants in the intervention group will attend a weekly, two-hour group session for 6 weeks, facilitated by trained healthcare workers, focusing on self-management of FDs through AT. Additionally, participants will receive up to five AT devices tailored to their specific functional disabilities needs, along with training on their usage. All participants will be assessed at baseline, post-intervention, and six months after intervention. The goals of the VIVE-AT are to encourage participants to use AT devices to self-manage their FDs and improve their quality of life. This approach will contribute to scientific knowledge and inform a subsequent scalable multisite Hybrid Type I Randomized Controlled Trial designed to evaluate its effectiveness in reducing physical function disabilities among older Latinos in primary healthcare settings in the U.S. and P.R.
