A study published in JAMA Cardiology sought to establish if publicly reported measures of a hospital’s 30-day all-cause mortality after percutaneous coronary intervention was associated with its mortality rates in subsequent years. In the study, on the basis of risk-adjusted percutaneous coronary intervention–related mortality rates from 1998 to 2016 at 67 New York hospitals (960 hospital-years), the hospital observed to expected mortality ratio was weakly associated with the ratio in the following year. Hospitals identified as outliers with high or low mortality experienced regression to the mean the following year. The study found that annual hospital-level percutaneous coronary intervention–related mortality rates were poorly associated with future performance but may not be useful for helping patients identify high-quality, low-mortality care.
