Comparison of Outcomes for Non-ST Elevation Acute Myocardial Infarction in Weekday vs Weekend Admissions: The Weekend Effect
Background Recent literature shows that reduced staffing over the weekends in hospitals may compromise patient care with acute conditions like acute coronary syndrome (ACS). Objective Our study evaluated differences in the outcomes between patients presenting with non-ST segment elevation acute coronary syndrome (NSTE-ACS) on weekends versus those coming on weekdays. Methods A single-center retrospective study was performed on NSTE-ACS patients. Data were analyzed using SPSS version 22 to calculate an independent sample t-test value for significance between the two groups. Results The mean DTB time for patients admitted over the weekend was significantly higher than those admitted over weekdays (p=0.000). The mean peak troponin level and length of stay (LOS) for patients admitted over the weekends vs. weekdays was significantly higher by 5ng/dL (9.71±5.23 vs. 4.194 ±2.60, p=0.0001) and 24 hours (72 ± 10 vs. 48 ± 6 hours, p=0.003), respectively. While the mean left ventricular ejection fraction (EF) of patients on discharge was lower by 5% for patients admitted over the weekend compared to patients admitted on weekdays (p=0.001). Conclusion: NSTE-ACS patients admitted over the weekends have a significantly higher myocardial injury evidenced by an increased LOS, higher peak troponin levels, and reduced EF due to delayed PCI compared to weekday admissions.
