O'Leary JD, et al. - A total of 159,101 adult cases from Ontario health administrative and demographic databases, were studied from January 1, 2005, to December 31, 2015, to assess the impact of weekend on hospital admission and 30-day mortality for subjects who had surgery on the same weekend. Researchers noticed that the 30-day all-cause mortality for candidates admitted on weekends (had noncardiac surgery) was 2.6% vs 2.5% for those who were admitted and had surgery on weekdays. Although, there was significant heterogeneity in the enhanced odds of death according to the urgency of admission and when surgery was performed.
