Newly and Previously Eligible Medicaid Enrollees Differ, but Not in Health Care Expenditures.

In 2014, the Affordable Care Act (ACA) expanded the role of Medicaid by encouraging states to increase eligibility for lower-income adults. As of 2024, 10 states had not adopted the expanded eligibility provisions of the ACA, possibly due to concerns about the state's share of spending. Using the Medical Expenditure Panel Survey (MEPS), we documented how health care utilization, expenditures, and the overall health status of newly eligible enrollees compare with enrollees who would have been eligible under their states' rules before the ACA. Our estimates suggest that, during 2014-16, newly eligible Medicaid enrollees had worse health and greater utilization and expenditures than previously eligible enrollees. However, during 2017-19, newly and previously eligible enrollees had comparable per capita health expenditures across six types of health spending. We find some evidence that changes in Medicaid enrollment composition muted observed differences between eligibility groups.

Catholic Hospital Affiliation and Postpartum Contraceptive Care and Subsequent Deliveries.

Importance: In recent years, the number of Catholic hospitals has grown, raising concerns about access to contraception. The association between living in an area in which the closest hospital is Catholic and the probability of postpartum contraception and subsequent deliveries is unknown. Objective: To assess whether living in an area in which the closest hospital was Catholic was associated with the probability of postpartum contraception and subsequent deliveries. Design, Setting, and Participants: This cohort study used data from the Healthcare Cost and Utilization Project's State Inpatient Databases, State Emergency Department Databases, and State Ambulatory Surgery and Services Databases for 11 states (California, Florida, Georgia, Missouri, Nebraska, Nevada, New York, South Carolina, Tennessee, Vermont, and Wisconsin). Female patients with a delivery from 2016 to 2019 who lived within 20 miles of a nonfederal acute care hospital were included, with patients followed up for 1 to 3 years. Coarsened exact matching was used to match patients based on the county-level percentage of the population affiliated with Catholic churches and urbanicity, and the zip code-level number of hospitals within 5 and 20 miles, median household income, and percentage of the population by race and ethnicity. Data were analyzed from April 2022 to November 2023. Exposures: Residence in a zip code in which the closest hospital was Catholic. Main Outcomes and Measures: Probabilities of delivery at a Catholic hospital, surgical sterilization within 1 year of delivery, receipt of long-acting reversible contraception at delivery, and subsequent delivery within 3 years. Results: The sample consisted of 4 101 443 deliveries (1 301 792 after matching), with 14.5% of patients living in exposed zip codes (ie, where the closest hospital was Catholic). Living in exposed zip codes was associated with a 21.26-percentage point (pp) increase in the probability of delivery at a Catholic hospital (95% CI, 19.50 to 23.02 pp; 237.3% relative to the mean in unexposed zip codes; P < .001). Additionally, comparing exposed vs unexposed zip codes, the probability of surgical sterilization at delivery decreased by 0.95 pp (95% CI, -1.14 to -0.76 pp; P < .001) and the probability of sterilization in the year after discharge further decreased by 0.21 pp (95% CI, -0.29 to -0.13; P < .001). Subsequent deliveries within 3 years increased 0.47 pp (95% CI, -0.03 to 0.97 pp; 2.3% relative to the mean in unexposed zip codes; P = .07). Conclusions and Relevance: This cohort study finds that living in a zip code in which the closest hospital was Catholic was associated with a modest decrease in the probability of postpartum surgical sterilizations and a modest increase in the probability of subsequent deliveries.
