Background: Day and month of admission has been shown to be an important predictor in other cardiac related admissions. We aim to show the impact of admission day in patients hospitalized for non-ST elevation myocardial infarction (NSTEMI) in the United States.
Methods: This was a retrospective cohort study using the 2013 National Inpatient Sample (NIS). The inclusion criteria were age older than 18 years and an ICD-9 CM code for primary diagnosis of NSTEMI. The data was analyzed based on admission on weekend: group 1 (12:00 AM Monday and 11:59 PM Friday) and weekday: group 2 (12:00 AM Saturday to 11:59 PM Sunday). Our main outcome measurements were in-hospital mortality and total hospitalization charges. Multivariate logistic regression was used to adjust for potential confounders including age, gender, and the Charlson Comorbidity index for administrative data.
Results: We included a total of 422,795 patients admitted with NSTEMI. The mean age was 68 years and 59% of patients were female. The likelihood of in-hospital mortality was not increased in group 1. Patients admitted over the weekend were less likely to get PCI. In the secondary outcomes, groups 1 and 2 did not have a significant difference in LOS. The average total hospital charges for group 1 was less compared to group 2.
Conclusions: Inpatient mortality and length of stay is not different between patients admitted over the weekend vs weekday. Although, weekend admissions were less likely to undergo PCI.
