Jang SJ, Yeo I, Feldman DN, et al. - Using the Nationwide Readmissions Database, researchers examined the link between length of hospital stay (LOS), readmission rate, and overall expenses in patients who had primary percutaneous coronary intervention for ST‐segment–elevation myocardial infarction (STEMI). In the anterior wall (AW) STEMI group and in the non‐AW STEMI group, the 30‐day readmission rate following percutaneous coronary intervention for STEMI was estimated to be 12.0% and 9.9%, respectively. In both the AW STEMI group and the non‐AW STEMI group, the lowest total expenses (index admission+readmission) were reported in the very short LOS cohort. Overall, findings revealed a significantly lower 30‐day readmission and lower cumulative cost in relation to a very short LOS, among patients who were treated with primary percutaneous coronary intervention for STEMI. However, higher 30‐day mortality was reported in relation to a very short LOS vs at least a 3‐day stay in the AW STEMI cohort.
