"Veteran to Veteran, There's Automatically a Trust": A Qualitative Study of Veterans' Experiences in a Peer Health-Coaching Program for Hypertension.

Introduction: Veteran peer Coaches Optimizing and Advancing Cardiac Health was an randomized controlled trial (RCT) to test the effectiveness of a peer support intervention to reduce blood pressure among veterans with hypertension and 1 or more cardiovascular risks. The authors studied participant perceptions of the intervention, including barriers and facilitators to participation, factors promoting behavior change, and disease self-management practices.

Methods: The authors enrolled participants at their exit visit for the Veteran peer Coaches Optimizing and Advancing Cardiac Health study. Participants received primary care at the Veterans Administration healthcare system and had multiple cardiovascular disease risks, including a diagnosis of hypertension. The authors conducted a qualitative content analysis of semistructured interviews about their experience with the Veteran peer Coaches Optimizing and Advancing Cardiac Health intervention.

Results: Interview participants (N=29) were aged 60 years on average (SD=8.6), were 71% male, and were 55% White. They had mean systolic blood pressure of 138 mmHg (SD=18) at baseline. Authors identified themes across 3 major categories, which follow the general progression of the intervention: participation, relationship building, and behavior change. Scheduling flexibility, shared identity and experiences with the coach, acquisition of new knowledge and skills, and goal setting were important determinants of participants' experiences in the program. In the participation category, the themes were scheduling, visit modality, life circumstances, and staffing. In the relationship category, the themes were the coach's professional role, shared identity and experiences, and social support. In the behavior change category, the themes were memory, attention, and decision processes; goal setting; skills and knowledge; and environmental context and resources. Authors report differences across patients varying by blood pressure reduction after the intervention and number of coaching visits.

Conclusions: Participants generally reported positive experiences in a peer support intervention for veterans with hypertension. Participant perceptions provide important insights into the intervention design and implementation. These findings may inform future implementation of peer support among veterans in hypertension and chronic disease self-management more generally.
