Association of rural and critical access hospital status with patient outcomes after emergency department visits among Medicare beneficiaries.
This study compared 30-day mortality rates after emergency department (ED) visits to rural or critical access hospitals (CAHs) compared to urban hospitals for Medicare beneficiaries. A 20% sample of Medicare beneficiaries was used from January 2011 to October 31, 2015. The primary outcome measured was 30-day mortality. Secondary outcome examined was ED visits with and without rehospitalization. Mortality rates were comparable with both groups, although patients in rural EDs experienced more transfers and less hospitalization.

Changes in hospital-acquired conditions and mortality associated with the hospital-acquired condition reduction program.
This study evaluated changes in Hospital-Acquired Conditions (HACs) and 30-day mortality after the announcement of the Centers for Medicare and Medicare Services’ Hospital-Acquired Condition Reduction Program (HACRP) in August 2013. The authors evaluated models to test for changes in HACs and 30-day mortality before and after the Affordable Care Act (ACA), and after the HACRP. Fee-for-service Medicare claims from 2009 to 2015 were used. The HAC rate declined after the ACA was passed and declined further after the HACRP announcement. However, 30-day mortality rates were unchanged.

Black-white disparities in maternal in-hospital mortality according to teaching and black-serving hospital status.
This study’s objective was to determine whether black-white disparities in maternal in-hospital mortality during delivery vary across hospital types (black-serving vs non-black and teaching vs non-teaching) and whether overall maternal mortality differs across hospital types. The authors performed a population-based, retrospective cohort study of 5,679,044 deliveries among black (14.2%) and white patients (85.8%) in 3 states (California, Missouri, and Pennsylvania) from 1995 to 2009. Examination of black-white disparities found that after risk adjustment, black patients had significantly greater risk of death and that the disparity was similar within each of the hospital types. At teaching hospitals, mortality was similar in black-serving and nonblack-serving hospitals. Among non-teaching hospitals, mortality was significantly higher in black-serving vs nonblack-serving hospitals. Over half (53%) of black patients delivered in nonteaching black-serving hospitals compared with just 19% of white patients.

Characteristics, outcomes, and trends of patients with COVID-19-related critical illness at a learning health system in the United States.
This study’s objective is to describe the epidemiology of COVID-19-related critical illness, including trends in outcomes and care delivery, using five hospitals within the University of Pennsylvania Health System as a setting. Findings showed that, among patients with COVID-19-related critical illness admitted to ICUs of a learning health system in the United States, mortality seemed to decrease over time despite stable patient characteristics. Recommendations included further studies to confirm this result and to investigate causal mechanisms.
