Sandhu AT, et al. - Researchers used data from the New York Percutaneous Intervention Reporting System (1998-2016) to assess the link between reported risk-adjusted hospital percutaneous coronary intervention (PCI)-associated mortality and a hospital’s future PCI-related mortality. They included 67 New York hospitals and 960 hospital-years. They found the regression of the rates, to a large extent, to the mean the following year at hospitals with high or low PCI-related mortality rates. They also found a poor correlation between a hospital’s risk-adjusted mortality rate and its future mortality. According to the findings, the reliability of the annual hospital PCI-related mortality as a factor related to hospital quality is possibly not up to the mark to support its consideration in a practice change or when assisting patients select high-quality hospitals.
