Insurance-based disparities in stroke center access in california: a network science approach.
The purpose of this study was to examine whether there is a relationship between ischemic stroke patient insurance and probability of transfer to a stroke center overall as well as whether hospital cluster modified the relationship between insurance and likelihood of stroke center transfer. The study included 332,995 total ischemic stroke encounters, with 3.5% transferred from the initial ED. The study found that of 52,316 participants presenting to a non-stroke center, 7.1% were transferred. Compared to privately insured patients, there were lower odds of transfer and of transfer to a stroke center among all groups. Within the 14 identified hospital clusters, there was variation in insurance-based disparities in transfer. The largest hospital was also the lowest performing cluster which fully explained the insurance-based disparity in odds of stroke center transfer. The study concluded that uninsured patients had lower stroke center access through transfer than patients with insurance, with the variation primarily explained by patterns in 1 specific hospital cluster.

Late postpartum coverage loss before COVID-19: implications for Medicaid unwinding.
The purpose of this study was to explore the loss of Medicaid coverage in toward the end of the postpartum period prior to COVID-19 and describe the implications for Medicaid unwinding. The researchers utilized unique Pregnancy Risk Assessment Monitoring System follow-up data from prior to the COVID-19 pandemic. The study found that only 68% of enrollees in prenatal Medicaid maintained continuous Medicaid coverage through 9 or 10 months postpartum. Of the total prenatal Medicaid enrollees who lost their coverage in the early postpartum period, two-thirds continued to be uninsured 9 to 10 months postpartum. The researchers concluded that extensions to state postpartum Medicaid could prevent a return to postpartum coverage loss rates similar to the level in the prepandemic period.

The effects of the Medicaid expansion on hospital utilization, employment, and capital.
This AHRQ-authored paper describes the effect of the Affordable Care Act Medicaid expansion on hospital utilization, employment, and capital. The authors conducted a difference-in-differences analysis that compared changes to hospital demand and supply in Medicaid expansion and nonexpansion states. They used 2010-2016 data from the American Hospital Association and the Healthcare Cost Report Information System to quantify changes to hospital utilization and characterize how hospitals adjusted labor and capital inputs. Medicaid expansion was associated with increases in emergency department visits and other outpatient hospital visits. They found strong evidence that hospitals met increases in demand by hiring nursing staff and weaker evidence that they increased hiring of technicians and investments in equipment. They found no evidence that hospitals adjusted hiring of physicians, support staff, or investments in other capital inputs.
