Propofol, the preferred sedation for screening colonoscopy, is underused. Results of an international survey.

Abstract: Background: The use of propofol during colonoscopy has become more widespread. To increase availability while maintaining quality and decreasing costs, European Guidelines have been issued for non-anesthesiologist administration of propofol (NAAP). We aimed to assess the current use of propofol during screening colonoscopy. Methods: International survey. Results: Eighty-four questionnaires were collected from endoscopists practicing in 29 countries. Practices were most often located in high-volume community hospitals (Italy, Belgium, Spain, Netherlands in half cases). An anesthesiologist was regularly present in the Endoscopy Unit of 69.0% survey respondents. In low-risk (ASA classification, 1–2) patients, propofol, benzodiazepine+opioids and benzodiazepine alone were used in 45%, 31% and 14% of screening colonoscopies, respectively. Propofol was associated with the highest endoscopist satisfaction (score on a 10-point visual analogue scale, 9.2±1.2 vs. 5.5±1.9 and 4.7±2.0 for benzodiazepine+opioids and benzodiazepine alone, respectively; P <0.0001). NAAP was used by 29.9% of respondents in 9 countries and approximately two-thirds of other endoscopists would consider implementing NAAP. Main reasons for not considering NAAP implementation were medico-legal issues and cost. Conclusion: Propofol provides the highest endoscopist satisfaction but it is used in less than half of screening colonoscopies. Propofol is administered by non-anesthesiologists in one-third of settings; its implementation is foreseen by a majority of endoscopists who do not currently use it. [Copyright &y& Elsevier]
