Variation in hospital length of stay in patients with acute myocardial infarction undergoing primary angioplasty and the need to change the diagnostic-related group system

Our findings show significant variation in length of hospital stay among patients with acute myocardial infarction treated with primary percutaneous coronary intervention; length of stay can be predicted from baseline clinical and angiographic characteristics. Our investigation suggests the need for a multi-tier diagnostic-related group system for patients with acute myocardial infarction treated with percutaneous coronary intervention.
