Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

This innovative study will measure the impact of Affordable Care Act-sponsored Medicaid expansions on access to and utilization of community health center (CHC) services. Building on the investigators prior work that developed a robust community-based research infrastructure within the OCHIN community health information network, the investigator will utilize linked electronic health record data from the OCHIN network of \>400 CHC clinics in 8 states that expanded Medicaid coverage and 8 states that did not expand.
