To the Editor Dr Rajaram and colleagues1 reviewed 4 important concerns about current use of the Agency for Healthcare Research and Quality’s (AHRQ) Patient Safety for Selected Indicators (PSI-90) metric to measure adverse events. These concerns included surveillance bias leading to increased detection of events, multiple financial penalties because of redundant measurements, inaccurate measurement of clinically relevant complications, and poor risk adjustment among hospitals with different patient demographics and comorbidities.
