Where do Oregon Medicaid Enrollees seek outpatient care post-Affordable Care Act Medicaid expansion?
The purpose of this study was to understand where Oregon Medicaid beneficiaries sought care after the Patient Protection and Affordable Care Act Medicaid expansion (emergency department, primary care, or specialist) and the interaction between primary care establishment and outpatient care utilization. Results showed that most newly and returning-insured Medicaid enrollees sought primary care rather than emergency department services and most became established with primary care, suggesting that both insurance and primary care continuity play a role in where patients seek health care services.

Following uninsured patients through Medicaid expansion: ambulatory care use and diagnosed conditions.
The authors assessed ambulatory care use and diagnosed health conditions among a cohort of community health center (CHC) patients uninsured before enactment of the Affordable Care Act (ACA) and followed them after enactment. They found that, post-ACA, 20.9% of patients remained uninsured, 15.0% gained Medicaid, 12.4% gained other insurance, and 51.7% did not have a visit. The authors concluded that a significant percentage of CHC patients remained uninsured; that many who remained uninsured had diagnosed health conditions; and that one-half continued to have three or more visits to CHCs, which continue to be essential providers for uninsured patients.

Appropriateness of outpatient antibiotic prescribing among privately insured US patients: ICD-10-CM based cross sectional study.
This study used ICD-10 codes to determine the appropriateness of outpatient antibiotic prescriptions filled in privately insured patients in the US. Determinations were made based on diagnosis whether the prescriptions were “appropriate”, “potentially appropriate”, “inappropriate”, or no diagnosis code found. Among a cohort of over 19 million, only 12.8% were deemed appropriate, 23.2% were inappropriate, 35.5% potentially inappropriate, and 28.% not associated with a diagnosis code.
