The U.S. Agency for Healthcare Research and Quality (AHRQ) has developed measures of quality and patient safety by using information found on hospital bills. These measures are considered less reliable than those which are based on intensive review of medical records because the diagnosis and procedure data on bills are not very detailed. However, these measures are very easy and inexpensive to prepare, and they can be one part of an overall review of quality and safety.
“The Agency for Healthcare Research and Quality (AHRQ) Quality Indicators (QIs) are measures of health care quality that make use of readily available hospital inpatient administrative data…. Inpatient QIs reflect quality of care inside hospitals including inpatient mortality for medical conditions and surgical procedures…Patient Safety Indicators also reflect quality of care inside hospitals, but focus on potentially avoidable complications and iatrogenic events.”
