Community Health Needs Assessments (CHNAs) have emerged as a pivotal element in improving population health in the United States. These assessments, mandated for non-profit hospitals under the Affordable Care Act (ACA), aim to identify and address significant health needs within communities. By working together with health departments and community organizations, hospitals can create comprehensive strategies to improve health outcomes and ensure health equity. This blog delves into a recent study that analyzed ten exemplary CHNA processes to identify best practices and the implications for evaluation practice.

The Importance of Community Health Needs Assessments

CHNAs offer an extraordinary opportunity to bridge the efforts of healthcare delivery sectors, public health agencies, and community organizations. These assessments can potentially refocus hospital community benefits towards improving population health, estimated to be around $62 billion in 2011. Despite their potential, many CHNAs lack clear, measurable objectives and evaluation plans, hindering their effectiveness.

Ten Best Practices in Community Health Needs Assessments

Community Health Needs Assessments (CHNAs) are essential for identifying and addressing significant health needs within communities. The following best practices highlight effective strategies for creating and implementing CHNAs to improve population health outcomes and ensure health equity.

1. Collaborative Data Collection. Incorporate data from multiple counties and regions served by local hospitals. This approach ensures comprehensive data coverage and addresses health needs across broader geographic areas, facilitating collaboration among different health entities.

2. Detailed Geographic Breakdown. Utilize maps and data that show health outcomes, such as life expectancy, by smaller geographic areas like zip codes or neighborhoods. This granular approach allows for targeted interventions in high-need areas and helps to identify specific health disparities.

3. Community Engagement. Conduct community surveys and involve various stakeholders, including healthcare providers, public health departments, and community organizations. Engaging the community ensures that the CHNA reflects the real health needs and concerns of the population.

4. Integrated State Health Indicators. Reference and align local health priorities with state-wide health objectives and improvement processes. This alignment helps ensure consistency and supports broader public health goals.

5. Comprehensive Data Sources. Use a variety of data sources, including vital statistics, hospitalization data, and survey data like the Behavioral Risk Factor Surveillance System (BRFSS). Multiple data sources provide a thorough health profile of the community.

6. Health Disparities Mapping. Include maps and data that highlight disparities in health outcomes by neighborhood, race, ethnicity, and socioeconomic status. Identifying these disparities is crucial for developing targeted health interventions and promoting health equity.

7. Focus on Local Health Surveys. Conduct local health surveys similar to BRFSS to gather detailed information on health behaviors and outcomes specific to the community. These surveys provide valuable insights that can guide targeted health interventions.

8. Robust Survey Data. Gather comprehensive survey data from a representative sample of the community. Large sample sizes and diverse data sources ensure that the survey results accurately reflect the community’s health needs and priorities.

9. Standardized Data Dashboards. Implement standardized data dashboards with trends and benchmarks to facilitate easy comparison and trend analysis. Dashboards help visualize data and identify priority health issues more effectively.

10. Data Integration. Integrate various data sources into a comprehensive platform that includes publicly available indicators covering social and economic factors, health behaviors, physical environment, clinical care, and health outcomes. A robust data integration approach ensures a thorough and holistic health assessment.

Common Challenges and Data Sources

One of the main challenges identified is the variability in data sources and formats. CHNAs commonly use data from the Census, American Community Survey, vital statistics, and survey data like the Behavioral Risk Factor Surveillance System (BRFSS). However, most data are available only at the county level, making it difficult to set priorities or monitor progress for populations served by hospitals with broader or narrower service areas.

Achieving Collective Impact through Shared Measurement Systems

For CHNAs to achieve their full potential, having a shared measurement system is crucial. This system should:

1. Include common indicators to track progress.
2. Collect, store, analyze, and report valid and reliable data.
3. Ensure data is actionable, timely, meaningful, and targeted to goals.

Case Studies and Best Practices

The study highlighted several best practices from the reviewed CHNA processes:

1. Ashland-Boyd County, KY: The CHNA includes data from multiple counties served by local hospitals, demonstrating a collaborative approach to data collection and analysis.
2. Bexar County, TX: The CHNA includes data broken down by sub-county areas, helping to identify specific health needs within smaller geographic regions.
3. San Francisco, CA: The CHNA uses neighborhood-level data, enabling targeted interventions in areas with the most significant health disparities.

Implications for Policy and Practice

To improve the effectiveness of CHNAs, it is essential to:

1. Develop population health data that can be disaggregated to appropriate geographical levels and demographic groups.
2. Enhance practitioners’ knowledge and skills in using population health data effectively.

Sharing Best Practices

Healthcare providers, public health agencies, and community organizations can benefit from sharing best practices and lessons learned from successful CHNA processes. By collaborating and utilizing shared measurement systems, these entities can more effectively address community health needs and promote health equity. We invite you all to share their best practices and experiences with CHNAs. How have you overcome challenges in data collection and analysis? What strategies have been most effective in your community? Your insights can help others improve their CHNA processes and ultimately enhance population health outcomes.
