Weekend versus weekday mortality in myocardial infarction in the United States: Data from healthcare cost and utilization project nationwide inpatient sample

摘要

Acute myocardial infarction (MI) is one of the leading causes of mortality in adults in the United States, affecting nearly one million patients per year [1]. While, some authors have found a positive association between weekend presentation and mortality [2], others have not shown a difference in weekend admissions [3]. A recent systematic review (including both of the above trials) concluded that mortality was indeed higher for MI patients presenting on weekends [4j. We attempted to clarify this observation using data from the largest inpatient database in the United States, the Nationwide Inpatient Sample (NIS), Healthcare Cost and Utilization Project (HCUP).
