Community health workers (CHWs) are frontline public health workers who share life experience, language, and often cultural background with the communities they serve, occupying a distinct role between formal clinical staff and the patients navigating a health system that can feel confusing or unwelcoming. The role has existed informally for decades in community health settings, but health systems and payers have increasingly formalized and funded it as part of value-based care and health equity strategies.
What CHWs Actually Do
A community health worker's core function is building trust and translating between the health system and the patient — helping a patient understand a diagnosis or treatment plan in accessible language, accompanying them to appointments, following up on social determinants of health screening results with actual referrals and follow-through, and providing the kind of sustained, relationship-based support that a time-constrained clinical visit rarely allows. Because CHWs typically come from the same community and often share lived experience with the conditions or barriers patients face, they can build a level of trust that clinical staff, however well-intentioned, sometimes cannot replicate.
The Evidence Base Is Genuinely Strong
Community health worker interventions have one of the more robust evidence bases in the broader health equity and social determinants literature, with multiple randomized controlled trials showing improved chronic disease control, reduced emergency department utilization, and improved patient satisfaction among populations supported by CHW programs, particularly for complex patients with multiple chronic conditions and significant social barriers to care. This evidence quality has helped CHW programs secure more durable institutional and payer support than some other health equity interventions with thinner outcome data.
Training and Certification Vary Considerably by State
Unlike more standardized clinical roles, community health worker training and certification requirements vary substantially by state — some states have formal CHW certification programs with defined curricula and continuing education requirements, while others have no formal certification structure at all, relying instead on employer-provided training. This variability has created ongoing debate within the field about whether standardizing certification nationally would strengthen the workforce's professional standing and reimbursement prospects, or whether it risks imposing rigid credentialing requirements on a role whose core value comes precisely from lived community experience rather than formal clinical training.
Reimbursement Has Historically Been the Bottleneck
For most of the CHW model's history, funding has come from grants, health system community benefit budgets, or public health department funding rather than direct billable reimbursement — a structural fragility that has made CHW program funding vulnerable to budget cycles even where outcome evidence is strong. This has begun to change: a growing number of state Medicaid programs now allow CHW services to be billed directly under specific procedure codes, and several value-based care and ACO arrangements have built CHW staffing directly into their care management model, recognizing the intervention's demonstrated ability to reduce costly downstream utilization.
Integration With Clinical Teams Requires Deliberate Design
CHW programs that succeed long-term generally build explicit workflows connecting CHWs to the clinical care team — shared documentation systems, regular case conferences, and clear escalation pathways when a CHW identifies a clinical concern during a home visit — rather than operating as a fully separate parallel track. Programs that treat CHWs as isolated from the clinical team have shown weaker outcomes than those that genuinely integrate the role into care coordination.
Conclusion
Community health workers fill a genuine gap between clinical care and the lived reality of patients navigating social and economic barriers to health, backed by an unusually strong evidence base for a health equity intervention. Their growing integration into value-based care models reflects real, measurable impact rather than a purely symbolic diversity initiative. Care teams working alongside CHWs depend on patient care supplies that support the home-based and community visits this workforce increasingly performs.
