Abstract
Background: Data from multiple surgical studies and settings have reported an increase in adverse events in patients admitted or treated on weekends. The aim of this study was to investigate short-term outcomes for patients undergoing carotid endarterectomy (CEA) in Australia and New Zealand based on the day of surgery.
Methods: This is a retrospective observational cohort study. Analysis of 7,857 CEAs recorded for more than 4 years in the Australasian Vascular Audit database was performed. Multivariate logistic regression was used to compare the following outcomes between CEAs performed during the week and on the weekend: (1) in-hospital stroke and/or death; (2) other postoperative complications; and (3) shorter (2 days or less) length of stay (LOS).
Results: A total of 7,857 CEAs were recorded, with significantly more procedures performed during the week (n = 7,333, P < 0.001). There was no statistically significant difference in the frequency of stroke and/or death or other complications between CEAs performed during the week or on the weekend (P = 0.294 and P = 0.806, respectively). However, there was a significant difference in LOS for procedures performed during the weekend, with more of these patients being discharged within 2 days compared with procedures performed during the week (56.8% vs. 51.5%; P = 0.003). Multivariable logistic regression found no effect of day of the week on the odds of postoperative stroke and/or death (P = 0.685). Day of surgery was also not associated with greater odds of other complications (P = 0.925). However, CEAs performed by nonconsultants had significantly lower adjusted odds of other complications (3.1% vs. 4.1%; P = 0.033). The adjusted odds of having a shorter LOS were significantly greater for operations taking place on the weekend (P = 0.003).
Conclusions: In Australia and New Zealand, there appears to be no disadvantage to performing CEA on the weekend, in terms of stroke and/or death. Level of experience of the primary operator does not affect rates of stroke and/or death after CEA. Weekend CEA is associated with a shorter hospital LOS.
