Abstract Background In the USA, sedation is commonly used for colonoscopies; though colonoscopy can be successfully performed without sedation, outcomes data in this setting are scarce. Aims To determine patient characteristics associated with undergoing unsedated colonoscopy and whether adenoma detection rate (ADR) and cecal intubation rate (CIR) differ between sedated and unsedated colonoscopy. Methods Using a single-center electronic endoscopy database, we identified patients who underwent outpatient colonoscopy between 2011 and 2018 with or without sedation. We used multivariable logistic regression to determine factors associated with unsedated colonoscopy, CIR, and ADR. Results We identified 24,795 patients who underwent colonoscopy during the study period. Of these, 179 patients (0.7%) underwent unsedated colonoscopy. ADR was 27.4% in sedated and 21.2% in unsedated colonoscopies (p = 0.06); CIR was 95.8% in sedated and 85.5% in unsedated patients (p 90% overall. The remainder of patient and colonoscopy characteristics are given in Table 1. ADR for the entire study population was 27.4%, and overall CIR was 95.7%. On univariable analysis (Table 1), patients who underwent colonoscopy without sedation were more often male (p
