Dataset Information

Impact of delirium on patients hospitalized for myocardial infarction: A propensity score analysis of the National Inpatient Sample.

ABSTRACT:

Background

Delirium is associated with worse outcomes in critically ill patients. In the subset of patients with myocardial infarction (MI), the impact on clinical outcomes of delirium is not as well elucidated.

Hypothesis

Delirium is associated with increased mortality in patients hospitalized for MI.

Methods

The study used data from the National Inpatient Sample 2012 to 2014, Healthcare Cost and Utilization Project. We included discharges associated with the primary diagnosis of MI using the relevant International Classification of Diseases, Ninth Revision, Clinical Modification codes. The outcome was inpatient mortality between the delirium group and propensity score-matched controls without delirium.
