Sources: Nevada Hospital Inpatient Data and the Agency for Healthcare Research and Quality

The Sun used federal Agency for Healthcare Research and Quality methods to compare accidental punctures or lacerations, as identified in Nevada hospital billing records, with expected national norms. AHRQ has developed software that risk-adjusts surgical injury cases in individual hospitals to create an “expected” rate of injuries. The rate at each hospital then can be fairly compared to the national rate. The Sun is reporting the percent difference between the expected rate, and the actual rate, of surgical injuries.
