Background: Over the past decade, advancements in troponin assay and percutaneous coronary intervention (PCI) have significantly improved clinical outcomes of Non-ST Elevation Myocardial Infarctions (NSTEMI). The aim of our study was to determine the effect of teaching hospital on NSTEMI outcomes.
Methods: We used the Nationwide Inpatient Sample (NIS) database of year 2013, for this retrospective cohort study. We included all the patients with age > 18 years with ICD-9-CM diagnosis code for NSTEMI. Following outcomes were compared for patients admitted to teaching vs non-teaching hospitals: In-Hospital mortality, resource utilization measured by total hospital charges, length of hospital stay (LOS), PCI and early PCI (which were defined as PCI in first 48 hours). Multivariate regression analysis was done to calculate the odds ratio.
Results: Total 418,889 NSTEMI patients were identified. Average age was 68 ± 0.07 years with 41% females. Multivariate regression analysis showed patient admitted to teaching hospital had higher in-hospital mortality (OR 1.09; 95% CI, p= <0.01), higher LOS (+0.67 days; p= <0.01) and higher resource utilization (+7890 USD; p= <0.01). However, they had higher likelihood of PCI (OR 1.41; 95% CI; p= <0.01) and early PCI (OR 1.36; 95% CI; p= <0.01).
Conclusions: NSTEMI Patients admitted in teaching hospital have higher likelihood of early PCI at the expense of higher LOS, resource utilization and in-hospital mortality.
