Community Health Workers (CHWs) have the potential to improve chronic disease outcomes among patients with low socioeconomic status (SES). Yet, widespread use of CHWs has been hampered by lack of standardized, scalable and evidence-based models. Our community-academic-health system team used participatory action research with low-SES patients to design IMPaCT (Individualized Management for Patient-Centered Targets). A randomized controlled trial (RCT) of 446 hospitalized patients with varied diseases demonstrated that a 2-week dose of IMPaCT improved access to care, mental health, activation, and quality of communication, while reducing recurrent hospital readmissions. We have adapted IMPaCT for use among low-SES primary care patients with multiple chronic conditions.
