Patient Safety Indicators — Agency for Healthcare Research and Quality
The Agency for Healthcare Research and Quality (AHRQ) is a federal agency for research on health care quality, costs, outcomes and patient safety.
AHRQ has created software that screens billing records for potentially preventable complications (adverse events) that patients sometimes experience while receiving medical care. Mayo Clinic tracks and analyzes these events, called patient safety indicators (PSIs), in an effort to prevent future occurrences.
The glossary below identifies the complications that are measured and defines them.
