What is a Community Health Needs Assessment?
A Plain-Language Guide
If you’re new to the Community Health Needs Assessment (CHNA) process, or just need a clear refresher before your next reporting cycle, here’s what it actually involves, why it exists, and what a good one looks like.
What is a CHNA?
A Community Health Needs Assessment is a systematic process hospitals use to identify the health needs of the community they serve. It combines data collection, community input, and analysis to answer one core question: what does this community need to be healthier, and where should resources go first?
Who has to do one, and how often?
Under the Affordable Care Act, tax-exempt hospitals are required to conduct a CHNA and adopt an Implementation Strategy every three years. The assessment has to be documented in a written report, approved by the hospital’s governing board, and made publicly available.
What does a CHNA actually involve?
A thorough CHNA typically includes:
- Defining the community the hospital serves, geographically and demographically
- Collecting primary data directly from community members, through surveys, interviews, or focus groups
- Collecting secondary data from public health sources like the CDC and Census
- Gathering input from public health experts and community leaders, not just residents
- Identifying and prioritizing health needs, since no hospital can address everything at once
- Assessing existing resources, so the plan builds on what’s already there instead of duplicating it
- Publishing a written report and Implementation strategy that’s approved by the hospital’s board
Why primary and secondary data both matter
Secondary data, like Census figures and CDC statistics, gives you an important baseline for understanding a community’s health status. But it can’t tell you what residents themselves say they need, or surface concerns that don’t show up in existing datasets. That’s why the strongest CHNAs pair secondary data with primary data collected directly from the community, through surveys and interviews. The combination gives hospitals a fuller, more accurate picture than either source alone, and it’s the foundation of a CHNA that actually holds up over the full three-year cycle.
Why this matters beyond compliance
Done well, a CHNA isn’t just a regulatory deliverable. It’s a genuine planning tool. It shapes where community benefit dollars go, which partnerships get built, and which health equity gaps actually get addressed. Hospitals that treat it as a checkbox exercise tend to get checkbox results. Hospitals that treat it as real research tend to get findings they can act on for the full three-year cycle.
