Do patient safety indicators explain increased weekend mortality?

This study sought to examine whether events captured by Patient Safety Indicators (PSIs) explain the "weekend effect" of higher hospital mortality.

This suggests that adverse events and the responses to adverse events are suboptimal on weekends, arguing for enhancements of weekend staffing.
