Population-level factors associated with maternal mortality in the United States, 1997-2012.
This study analyzed state-level maternal mortality for the years 1997-2012 using multilevel mixed-effects regression grouped by state, using publicly available data. The study concluded that, in addition to better case ascertainment of maternal deaths, adverse changes in chronic diseases, insufficient healthcare access, and social determinants of health represent identifiable risks for maternal mortality that merit prompt attention in population-directed interventions and health policies.

Heart and lung organ offer acceptance practices of transplant programs are associated with waitlist mortality and organ yield.
Variation in heart and lung offer acceptance practices may affect numbers of transplanted organs and create variability in waitlist mortality. In this study, the authors examined offered acceptance ratios, or adjusted odds ratios, for heart and lung transplant programs individually and for all programs within donation service areas (DSAs) using offers from donors recovered July 1, 2016, and June 30, 2017.

Excess mortality associated with weekend hospital admissions may be due to patient-level differences, rather than reduced staffing or services.
The author comments on a study by Walker that explained the weekend effect as arising from differences in patient characteristics among patients who present to the emergency department on the weekend. For staffing, Walker used a proxy measure because staffing information was not available. The author cautions that, although a clear rationale was provided, there should be acknowledgement that use of a proxy, whether for illness severity or staffing, may alter results.
