Relationship between a risk score for QT interval prolongation and mortality across rural and urban inpatient facilities.
The objectives of this retrospective observational study were to evaluate the relationship between a modified Tisdale QTc-risk score (QTc-RS), inpatient mortality, and length of stay in a broad inpatient population with an order for a medication with a known risk of torsades de pointes (TdP). Inpatient data from 28 healthcare facilities in the western US were used. The results indicated that there is a strong relationship between increased mortality as well as longer duration of hospitalization with an increasing QTc-RS.

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.

The synchronicity of COVID-19 disparities: statewide epidemiologic trends in SARS-CoV-2 morbidity, hospitalization, and mortality among racial minorities and in rural America.
Researchers sought to examine trends in COVID-19 morbidity, hospitalization, and mortality over time for minority and rural populations, especially during the U.S. fall surge. Data were taken from a statewide cohort of adult residents in Indiana tested for SARS-CoV-2 infection. The researchers found that, by the fall of 2020, hospitalization and mortality rates in rural areas surpassed those of urban areas, and gaps between black/brown and white populations narrowed. Cumulative morbidity and mortality were highest among minority groups and in rural communities. They concluded that the synchronicity of disparities in COVID-19 by race and geography suggested that health officials explicitly measure disparities and adjust mitigation as well as vaccination strategies to protect those sub-populations with greater disease burden.
