A new PCORnet® Population Insights Report provides a closer look at the characteristics of more than 50 million patients receiving healthcare services between January 1, 2025, and December 31, 2025, at organizations participating in PCORnet.
Drawing on data represented in electronic health records across all 50 U.S. states, the report provides insights into patient demographics, geography, and healthcare settings from sites participating in PCORnet.
The data are also stratified by each of the eight PCORnet® Clinical Research Networks (CRNs). This means researchers can design projects and include groups in their studies that are representative of different communities and varying levels of urbanization. The report can help researchers understand the breadth of PCORnet data resources available to answer research questions and recruit patients for future research.
A Closer Look At The Patient Population
PCORnet data resources offer access to a broad range of patient populations and standardized data, streamlining the research design and implementation process while maintaining rigorous privacy protections.
The patient population described in the report includes males and females across a variety of ages, races, and ethnicities. The demographic data include information about health insurance, showing:
- 40% of patients have private insurance
- 31% of patients have a form of public insurance, such as Medicare or Medicaid.
Additionally, 80% of patients reside in a metropolitan or urban area and 12% of patients reside in a rural area or small town.
While the report includes data on several healthcare visit types, approximately 87% of patients had at least one ambulatory visit in 2025 and 19% of patients had at least one emergency department visit during 2025.
Other Population Insights Reports include 11 topic-level reports that characterize the extensive, real-world patient data available through PCORnet data resources:
- Cancer
- Menopause
- Sensory Health
- Metabolic and Endocrine Conditions
- Women’s Health
- Gene Therapy
