“…Similarly, patients with acute myocardial infarction (MI) admitted during off-hours have been shown to have an increase in mortality, in addition to less usage of and increased time to invasive cardiac procedures [12, 13]. However, previous studies have been limited by either only including those suffering from ST-Elevation Myocardial Infarction (STEMI), a single component of ACS, or they have been limited by using a restricted regional cohort, such as data from a single state [14]. While the underlying cause of ACS dictates the appropriate intervention, and its timing, it is likely that those patients who present with ACS requiring revascularization are likely to have worse outcomes when admitted during the weekend, compared to those admitted during the weekdays.…”

Background We assessed in-hospital mortality and utilization of invasive cardiac procedures following Acute Coronary Syndrome (ACS) admissions on the weekend versus weekdays over the past decade in the United States. Methods We used data from the Nationwide Inpatient Survey (2001–2011) to examine differences in all-cause in-hospital mortality between patients with a principal diagnosis of ACS admitted on a weekend versus a weekday. Adjusted and hierarchical logistic regression model analysis was then used to identify if weekend admission was associated with a decreased utilization of procedural interventions and increased subsequent complications as well. Results 13,988,772 ACS admissions were identified. Adjusted mortality was higher for weekend admissions for Non-ST-Elevation Acute Coronary Syndromes [OR: 1.15, 95% CI, 1.14–1.16] and only somewhat higher for ST-Elevation Myocardial Infarction [OR: 1.03; 95% CI, 1.01–1.04]. Additionally, patients were significantly less likely to receive coronary revascularization intervention/therapy on their first day of admission [OR: 0.97, 95% CI: 0.96–0.98 and OR: 0.75, 95% CI: 0.75–0.75 for STEMI and NSTE-ACS respectively]. For ACS patients admitted during the weekend who underwent procedural interventions, in-hospital mortality and complications were higher as compared to patients undergoing the same procedures on weekdays. Conclusion For ACS patients, weekend admission is associated with higher mortality and lower utilization of invasive cardiac procedures, and those who did undergo these interventions had higher rates of mortality and complications than their weekday counterparts. This data leads to the possible conclusion that access to diagnostic/interventional procedures may be contingent upon the day of admission, which may impact mortality.

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 5 ng/dL (9.71 ± 5.23 vs. 4.194 ± 2.60, p = 0.0001) and 24 h (72 ± 10 vs. 48 ± 6 h, 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.
