Global Trigger Tool shows that adverse events in hospitals may be ten times greater than previously measured

Classen DC, Resar R, Griffin F, et al. Global Trigger Tool shows that adverse events in hospitals may be ten times greater than previously measured. Health Affairs. 2011 Apr;30(4):581-589.

 

This study compared three methods to detect adverse events in hospitalized patients, using the same patient sample set from three hospitals: voluntary reporting, the Agency for Healthcare Research and Quality's Patient Safety Indicators, and the IHI Global Trigger Tool. The IHI Global Trigger Tool found at least ten times more confirmed, serious events than these other methods. The authors submit that reliance on voluntary reporting and Patient Safety Indicators could produce misleading conclusions about the current safety of US health care and misdirect safety improvement efforts.
