Climate-Related Health Risks In US Hospital Community Health Needs Assessments: A Mixed-Methods Analysis

Nonprofit hospitals conduct a community health needs assessment every three years to maintain federal tax-exempt status. Federal rules do not require these assessments to consider climate-related health risks, despite evidence that climate change affects health and health care delivery. This study examined the extent to which hospitals address climate-related health in community health needs assessments. We reviewed a nationally representative sample of 566 community health needs assessments (2021–24) from 3,468 US hospitals. Climate-related content was scored on an eighteen-point rubric including climate hazards and health risks (for example, extreme heat and flooding). The assessments’ climate-related content was limited (mean score, 2.51 of 18). Hospitals serving more climate-vulnerable communities, especially those with greater socioeconomic disadvantage, were less likely to identify climate-related health risks. Scores in the Northeast and West were nearly twice those in the South and Midwest, although they were still low. Federal requirements should better align community health needs assessments with emerging public health risks, including climate change, to improve health system resilience.
