Achieving competence in colonoscopy: Milestones and the need for a new endoscopic curriculum in gastroenterology training

Table 2 Median performance scores (25%-75% interquartile range) on live-patient procedures among fellows trained on colonoscopy simulator vs trainees with bedside training alone[34]

Fellow performance parameters	Simulator fellow (n = 462)	Traditional teaching (n = 423)	P value
Time to reach maximum insertion (min)	20.0 (14.0-25.0)	20.0 (15.0-29.8)	0.170
Median depth of unassisted insertion (1 = rectum, 6 = terminal ileum)	5.0 (4.0-6.0)	5.0 (4.0-5.0)	0.002
% of colonoscopies completed independently	64.1% (59.7-68.5)	56.3% (51.6-61.0)	0.018
Identifies landmarks (1 = strongly disagree, 7 = strongly agree)	7.0 (6.0-7.0)	6.0 (6.0-7.0)	0.003
Inserts in a safe manner (1 = strongly disagree, 7 = strongly agree)	7.0 (6.0-7.0)	7.0 (6.0-7.0)	0.020
Adequately visualizes mucosa during withdrawal	7.0 (6.0-7.0)	6.0 (6.0-7.0)	0.009
Responds appropriately to patient discomfort	7.0 (6.0-7.0)	6.0 (6.0-7.0)	0.255
Patient-reported discomfort	1.0 (1.0-4.0)	1.0 (1.0-4.0)	0.090
