| Abstract: |
Because more older adults undergo surgical procedures, it is incumbent on us to learn how to provide them with the safest possible perioperative care. We conducted a retrospective cohort study at a large tertiary care center to determine whether outcomes after anesthesia-related adverse events differed between patients aged 65 years and older versus patients under age 65. One thousand four hundred twenty-four cases were referred to the Performance Improvement committee of the Department of Anesthesiology from the years 2007-2015. After exclusions of cases that were not anesthesia-related, could not be identified, or were duplicates, 747 cases with anesthesia-related adverse events were included in the study. Two hundred eighty-six were aged 65 years and older and 461 were under age 65. Anesthesia-related adverse events occurred more commonly in the postoperative period in older patients relative to younger patients (37.7% vs. 21.9%,p= .001), and older patients had a greater incidence of mortality compared with a propensity-matched group of younger patients (adjusted odds ratio 1.87 [1.14-3.12],p< .05). We concluded that older patients have a greater likelihood of mortality as a result of suffering an anesthesia-related adverse event and may benefit from increased vigilance in the postoperative period. |
