Multiple unplanned readmissions after discharge for an admission with percutaneous coronary intervention




Objective This study aims to describe temporal trends, characteristics, and clinical outcomes of patients with more than one unplanned readmission within 30 and 180 days aer admission with percutaneous coronary intervention (PCI). Background There is limited understanding of multiple readmissions aer PCI. Methods Patients undergoing PCI between 2010 and 2014 in the U.S. Nationwide Readmission Database were evaluated for unplanned readmissions at 30 and 180 days aer discharge. Trends in multiple readmissions, characteristics of patients, and causes of first readmissions are described. Results A total of 2,324,194 patients were included in the analysis of 30-day unplanned readmissions and 1,327,799 patients in the analysis of 180-day unplanned readmission. The proportions of patients with a single readmission and multiple readmissions within 30 days were 8.5 and 1.0% and at 180 days were 15.4 and 9.1%, respectively. Common reasons for first readmission among patients with multiple readmissions were coronary artery disease, including angina, heart failure, and acute myocardial infarction. Factors associated with multiple readmissions were discharge against medical advice, discharge to care home, renal failure, and liver failure. The total cost of multiple readmissions is significant, with an increase from similar to$20,000 for no readmission to over $60,000 at 30-day follow up and $86,000 at 180-day follow up. Conclusions Multiple readmissions are rare within 30 days aer PCI but increase to nearly 1 in 10 patients at 180 days, and 20-25% of patients who have multiple readmissions are readmitted for the same cause as for the first and second readmissions.
