Do patient safety indicators explain increased weekend mortality?

Ricciardi R, Nelson J, Francone TD, et al. The Journal of surgical research. 2016;200:164-70.

This study sought to examine whether events captured by Patient Safety Indicators (PSIs) explain the "weekend effect" of higher hospital mortality. Researchers found that rates of PSI events were similar, but weekend instances of PSI events in general have worse outcomes than those on weekdays. This suggests that adverse events and the responses to adverse events are suboptimal on weekends, arguing for enhancements of weekend staffing.
