Primary care access to new patient appointments for California Medicaid enrollees: a simulated patient study.
Investigators evaluated variation in the availability of primary care new patient appointments for Medi-Cal (California Medicaid) enrollees in Northern California and its relationship to emergency department (ED) use after Medicaid expansion. Data from the California Health Interview Survey, Medi-Cal enrollment reports, and California hospital discharge records were used. The investigators found that access to primary care in Northern California was limited for new patient Medi-Cal enrollees and varied across counties, despite standard statewide reimbursement rates. Further, counties with more limited access to primary care new patient appointments had higher ED use by Medi-Cal enrollees.

Emergency department and primary care use in Massachusetts 5 years after health reform.
The goal of this study was to identify characteristics of insured Massachusetts residents associated with primary care sensitive (PCS) emergency department (ED) use, and compare such use for public versus private insurees. The researchers used data on people under age 65 taken from the Massachusetts All-Payer Claims Data for 2011-2012. Their conclusions indicate that public insurance was associated with less access to primary care and more PCS ED use; statewide labor shortages and low reimbursement rates from public insurance may have provided inadequate access to care that might otherwise have helped reduce PCS ED use.
