Others included less common procedure types such as ileoscopies and pouchoscopies. There was a significant difference in the distribution of case types during the pre-pilot and pilot periods by Pearson’s Chi-squared test.
Some cases were “double procedures” when a patient underwent more than 1 procedure such as both upper endoscopy and colonoscopy in a single instance of sedation, thus the total number of individual procedures was greater than the total number of cases.
