We assessed the feasibility, acceptability, fidelity, and preliminary effect of a multicomponent, collaborative quality improvement (C-QIP) strategy among patients with CVD attending outpatient clinics in India.</p> <p>Methods and findings</p><p>In this pragmatic feasibility randomized controlled trial, 410 adults with ischemic heart disease, ischemic stroke, or heart failure attending four public and private hospitals were randomized to C-QIP (electronic decision support for providers, non-physician care coordination, patient education, text-message reminders, and audit-feedback) or usual care.

Primary outcomes were feasibility, fidelity, adoption, and acceptability; secondary outcomes included guideline-directed medical therapy (GDMT), self-reported adherence, care processes, and risk factors. At end of study (median follow-up 15 months), retention was 192/206 (93.2%) in C-QIP and 187/204 (91.7%) in usual care. Fidelity was high: 187/198 (94.4%) C-QIP participants received lifestyle counseling at end of study.
