Integrated care models and behavioral health care utilization: quasi-experimental evidence from Medicaid health homes.
This study provided the first population-level evidence on the effects of Medicaid health homes (HH) on behavioral health care service use. As of 2016, 16 states had adopted an HH for enrollees with serious mental illness and/or substance use disorder. Using data from the National Survey on Drug Use and Health, the authors found that HH adoption increased service use among enrollees and enrollee self-reported health improved post-HH.

Using electronic health records in longitudinal studies: estimating patient attrition.
This study’s objective was to estimate overall and among adults with diabetes or hypertension: 1) patient attrition over a 3-year period at community health centers; and 2) the likelihood that patients with Medicaid switched their primary care source. Data was collected from the retrospective cohort study of 2012-2017 claims data Accelerating Data Value Across a National Community Health Center Network (ADVANCE) Clinical Data Research Network of community health centers. This study focused on Oregon Medicaid enrollees with a total of 232,891 patients aged 19-64 with a gap of 6 months or more following a claim for a visit billed to a primary care source. The authors theorized the reason was due to patients with Medicaid permanently changing their primary care source. They found that attrition over 3 years averaged 33.5% but patients with diabetes or hypertension was lower (25% or less). Among Medicaid patients the attrition rate 12% for community health center patients compared with 39% for single-provider practice patients.

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.
