Why trusted community health workers are vital for public health equity
In short: For many formerly incarcerated individuals, the path to healthcare is blocked by systemic barriers. A recent study in New York City found that moving testing from offsite clinics to community-based organizations, led by trusted health workers, significantly increased the uptake of life-saving medical screenings.
The MOSAIC study, a randomized controlled trial conducted in New York City between April 2022 and May 2024, examined how to better manage COVID-19 risks among people released from incarceration within the last 90 days. This population faces unique challenges, including a history of elevated viral risk in carceral settings and a tendency to live in congregate housing post-release. The study compared a standard of care referral to offsite testing against a community-led intervention providing onsite point-of-care testing and education.
The results were compelling: 86% of participants in the community-health worker-led group received at least one complete SARS-CoV-2 test, compared to only 54% in the standard referral group. This represented an odds ratio of 5.9, suggesting that the proximity and trust established by community-based organizations are powerful drivers of health engagement. The intervention was designed to be culturally and geographically accessible, specifically targeting individuals fluent in English or Spanish.
The 'trust gap' represents a vital public health concept revealed by these results. Although the research centred on COVID-19, investigators observed that employing reliable local health staff for education and on-site screening could work for other pathogens, including hepatitis C and HIV. By meeting people where they are—physically and socially—health systems can overcome the structural barriers that often leave marginalized populations behind.
