Strengthening Primary Care Through Project ECHO^®: Pilot Study on Nutrition, Brain Health, and Clinician Self-Efficacy.

Abstract

Primary care clinicians are mostly the initial point of contact in providing patient care; however, many clinicians report inadequate training and a lack of confidence in promoting brain health among their patients from a nutrition perspective. This participatory mixed-methods study evaluated the impact of a Project ECHO® pilot program on clinicians' perceived self-efficacy in promoting brain health through nutrition among Latino older adults in South Texas. Employing an explanatory sequential design, a training curriculum was designed for primary care clinicians using the Project ECHO® model. Four virtual sessions were provided once a week on nutrition-related topics through the videoconferencing platform Zoom. Quantitative data were collected via pre- and post-program surveys (N = 13) and analyzed using the Wilcoxon signed-rank test in GraphPad Prism Version 10.6.0 to inform subsequent qualitative interviews. Thematic analysis was conducted to examine the transcripts from individual interviews with 4 of the 13 participating clinicians using Taguette (Version 1.3, Open-Source Software). Data indicated a statistically significant increase in mean self-efficacy scores among clinicians following program participation (<i>P</i> < .005). Participant satisfaction with the program exceeded 90%, and clinicians intended to integrate nutrition into brain health counseling with patients. Thematic analysis of individual interviews identified 3 key themes, including perceived training outcomes, evaluation of the study design, and suggested areas for program improvement. Findings suggest that the Project ECHO^® Nutrition and Brain Health program is a feasible intervention for improving clinician self-efficacy in delivering nutrition-based brain health care to Latino older adult populations. Future research should examine whether enhanced self-efficacy translates into practice change and improved patient outcomes.
