Access to obstetric, behavioral health, and surgical inpatient services after hospital mergers in rural areas.
This study examined the influence of rural hospital mergers on changes to inpatient service lines at hospitals and within their catchment areas. The authors used hospital discharge data from 32 HCUP Inpatient Databases from 2007 to 2018. They found that merged hospitals were more likely than independent hospitals to eliminate maternal/neonatal and surgical care. They also found that while the number of mental/substance use disorder-related stays decreased or remained stable at merged hospitals and their catchment areas, it increased for unaffiliated hospitals and their catchment areas. This indicates a potential unmet need in the communities of rural hospitals postmerger.

The impact of urgent care centers on nonemergent emergency department visits.
This study looked at the impact of urgent care centers on nonemergency emergency department (ED) use. Secondary data from a novel urgent care center database, linked to the HCUP State Emergency Department Databases (SEDD) from six states was used. Data from ZIP codes with no urgent care centers served as a control group compared to areas with local urgent care centers. Having an open urgent care center in a ZIP code reduced the total number of ED visits by residents by 17.2% largely due to visits for less urgent conditions. The effect was concentrated in areas with hospitals with the longest ED wait times. The total number of uninsured visits to the ED were reduced by 21% and for Medicaid visits by 29.1%.

Increased utilization of total joint arthroplasty after Medicaid expansion.
This study examined prior analyses that greater utilization of total hip arthroplasty (THA) and total knee arthroplasty (TKA) was to be expected after Medicaid expansion in 2014. Using 2012-2015 data from the HCUP Database, 9 expansion states (Arkansas, Arizona, Colorado, Iowa, Massachusetts, Maryland, Nevada, New York, and Vermont) were compared to 2 states that did not expand Medicaid (Florida and Missouri). After adjusting for community characteristics, THA and TKA increased 15% in 2014 and 23% in 2015 within expansion states compared to 2013. In non-expansion states, compared to 2013, there were significant decreases of 18% in 2014 and 11% in 2015.

The impact of halting elective admissions in anticipation of a demand surge due to the coronavirus pandemic (COVID-19).
This study’s objective was to estimate excess demand for hospital beds due to COVID-19 and the net financial impact of eliminating elective admissions to meet demand. An economic simulation was conducted combining epidemiological reports, the US Census, American Hospital Association Annual Survey, and the National Inpatient Sample. The base case used relied on a hospital admission rate reported by the CDC of 137.6 per 100,000, with the highest rates in people aged 65 year and older and 50-64 years. Elective admissions accounted for 20% of total hospital admissions, with an average rate of 30% unoccupied beds across hospitals. Hospitals that restricted elective care due to a COVID surge was only financial favorable if capacity was filled by a high proportion of COVID-19 cases among hospitals with low rates of elective admissions. There is a substantial financial risk to hospitals that restrict elective care.
