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.

Residential racial segregation and mortality among black, white, and Hispanic urban breast cancer patients in Texas, 1995 to 2009.
The authors investigated whether residential segregation was associated with mortality among urban women with breast cancer. They found that greater black segregation and Hispanic segregation were adversely associated with cause-specific mortality and all-cause mortality.
