30-Day Readmission for Patients Undergoing Percutaneous Coronary Interventions in New York State

30-Day Readmission for Patients Undergoing Percutaneous Coronary Interventions in New York State Edward L. Hannan, Ye Zhong, Harlan Krumholz, Gary Walford, David R. Holmes, Jr, Nicholas J. Stamato, Alice K. Jacobs, Ferdinand J. Venditti, Samin Sharma, Spencer B. King III This study analyzed 30-day readmissions after percutaneous coronary intervention (PCI) for 40,093 New York State PCI patients between January 1, 2007 and November 30, 2007. A total of 15.6% of all PCI patients were readmitted, and 20.6% of them were staged. The most common reasons for unstaged readmissions were chronic ischemic heart disease (22.5%), chest pain (10.8%), and heart failure (8.2%). Thirteen pre-procedural risk factors, as well as longer lengths of stay, were all associated with higher readmission rates. Future efforts to reduce readmissions should be directed toward the recognition of patients most at risk, and the reasons they are readmitted.
