A study published in Health Affairs reported that The Institute for Healthcare Improvement’s Global Trigger Tool found that hospital errors may be higher than previously reported.  The researchers compared three methods of detecting and measuring adverse events in hospitalized patients (adverse events included pressure ulcers, device failures and patient falls).

The researchers found “that the adverse event detection methods commonly used to track patient safety in the United States today—voluntary reporting and the Agency for Healthcare Research and Quality’s Patient Safety Indicators—fared very poorly compared to other methods and missed 90 percent of the adverse events.”
