Predictors of Postoperative Cognitive Dysfunction

For adults aged 65 years or older presenting for ambulatory surgery, 1 in 6 have preexisting cognitive impairment. There is a higher prevalence of cognitive impairment in patients with the following characteristics:

  • Age over 85 years, Male

  • Lower socioeconomic and education levels

  • History of stroke

  • Preoperative functional dependence

Although ambulatory surgery confers a lower risk of developing perioperative neurocognitive dysfunction than major procedures, these preexisting patient risk factors are more predictive.
