COACH trial: A randomized controlled trial of nurse practitioner/community health worker cardiovascular disease risk reduction in urban community health centers: Rationale and design

Research output: Contribution to journalArticlepeer-review

Abstract

Background: Despite well-publicized guidelines on the appropriate management of cardiovascular disease (CVD) and type 2 diabetes, implementation of risk-reducing practices remains poor. This paper describes the rationale and design of a randomized controlled clinical trial evaluating the effectiveness of a comprehensive program of CVD risk reduction delivered by nurse practitioner (NP)/community health worker (CHW) teams versus enhanced usual care in improving the proportion of patients in urban community health centers who achieve goal levels recommended by national guidelines for lipids, blood pressure, HbA1c and prescription of appropriate medications. Methods: The COACH (Community Outreach and Cardiovascular Health) trial is a randomized controlled trial in which patients at federally-qualified community health centers were randomly assigned to one of two groups: comprehensive intensive management of CVD risk factors for one year by a NP/CHW team or an enhanced usual care control group. Results: A total of 3899 patients were assessed for eligibility and 525 were randomized. Groups were comparable at baseline on sociodemographic and clinical characteristics with the exception of statistically significant differences in total cholesterol and hemoglobin A1c. Conclusions: This study is a novel amalgam of multilevel interdisciplinary strategies to translate highly efficacious therapies to low-income federally-funded health centers that care for patients who carry a disproportionate burden of CVD, type 2 diabetes and uncontrolled CVD risk factors. The impact of such a community clinic-based intervention is potentially enormous.
