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.

Post-acute care use patterns among hospital service areas by older adults in the United States: a cross-sectional study.
This study examined post-stroke acute care patterns across Hospital Service Areas among a national stroke cohort of Medicare beneficiaries to determine drivers of variation in post-acute care service utilization. Data was extracted from 2013 to 2014 (174,498 total records across 3232 Hospital Service Areas). Patients’ residence ZIP codes were linked to the facility ZIP code where care was received. Patients were considered a “traveler” if they did not live in the Hospital Service Area where they received care. Only 23.5% of all patients received care in skilled nursing-only Hospital Service Areas although 73.4% of all Hospital Service Areas were skilled nursing-only. Thirty-five percent of all patients traveled to a different Hospital Service Area from their residence. Patients living in skilled nursing-only Hospital Service Areas had more than 5 times the odds of traveling compared to those living in Hospital Service Areas with skilled nursing, inpatient rehabilitation, and long-term care hospital services.

Failure to administer recommended chemotherapy: acceptable variation or cancer care quality blind spot?
This study examined hospital variation in cancer patients who did not receive recommended chemotherapy. Patients with breast, colon, and lung cancers who did not receive chemotherapy from 2000 to 2015 were identified from the National Cancer Database. A total of 183,148 patients at 1281 hospitals were included. For breast cancer, 3.5% of patients failed to receive recommended chemotherapy, and 6.6% with colon, and 10.7% with lung cancer. Sociodemographic factors showed that patients were less likely to receive chemotherapy if they were uninsured or on Medicaid, as were non-Hispanic black patients with both breast and colon cancer. There was also significant hospital variation with failure to administer as high as 21.8% for breast, 40.2% for colon, and 40.0% for lung cancer.

Changes in hospital service demand, cost, and patient illness severity following health reform.
This study examined the effects of expanded Medicaid coverage and the health insurance exchange on the number of hospital inpatient and emergency department (ED) utilization rates, cost, and patient illness severity. There was a significant drop in uninsured inpatient discharges and ED visits in states where Medicaid was expanded. For all by young females, uninsured inpatient discharge rates fell by 39% or greater. In nonexpansion states, the rates remained unchanged or increased slightly. Changes in all-payer and private insurance rates were not as dramatic, as was inpatient costs per discharge and all-payer inpatient costs.
