Predictors of postcolonoscopy emergency department use

I read the recent article by Dr Grossberg et al1 with interest. In their retrospective cohort study, the authors identified multiple patient-related and endoscopist-related factors associated with an unplanned emergency department (ED) visit within 7 days of the index colonoscopic examination. Although not studied, a potentially important factor in determining an individual patient's propensity to seek ED evaluation might be the physician's threshold for recommending the same.
