Summary Background Propofol‐mediated sedation for endoscopy is popular because of its rapid onset and recovery profile. Aim To examine procedure‐specific occurrence and risk factors for cardiopulmonary events during propofol‐mediated upper endoscopy (EGD) and colonoscopy. Design A cohort study using the Clinical Outcomes Research Initiative database was used to determine the frequency of cardiopulmonary events. Clinical Outcomes Research Initiative consisted of 69 practice sites comprising 593 US endoscopists. Multivariate logistic regression analysis used variables, such as age, ASA classification and propofol administration by monitored anaesthesia care or gastroenterologist‐administered propofol to determine the risk of cardiopulmonary events. Results The overall cardiopulmonary event rate for 5928 EGDs and 11 683 colonoscopies was 11.7/1000 cases. For colonoscopy, ascending ASA classification was associated with an increased risk. Monitored anaesthesia care was associated with a decreased adjusted relative risk (0.5, 95% CI: 0.36–0.72). ASA I and II patients receiving monitored anaesthesia care for EGD exhibited a significantly lower relative risk (ARR 0.29, 95% CI: 0.14–0.64). For subjects with ASA class III or greater, there was no difference in the risk between monitored anaesthesia care and gastroenterologist‐administered propofol. Conclusions There are procedure‐specific risk factors for cardiopulmonary events during propofol‐mediated EGD and colonoscopy. These should be taken into account during future prospective comparative trials.
