Utilization of Community Health Centers in Medicaid Expansion and Non-Expansion States 2013–2014

摘要

Using electronic health record data, we examined longitudinal changes in community health center (CHC) visit rates from 2013 through 2014 in Medicaid expansion versus non-expansion states. Visits from 219 CHCs in five expansion states and four non-expansion states were included. Rates were computed using generalized estimating equation Poisson models. Rates increased in expansion state CHCs for new patient, preventive, and limited-service visits (14%, 41%, and 23%, respectively, P<.01 for all), while these rates remained unchanged in non-expansion states. One year after ACA Medicaid expansions, CHCs in expansion states saw an influx of new patients and provided increased preventive services.
