Patient Satisfaction With Sedated vs. Unsedated Colonoscopy

This is a prospective, observational study to evaluate patient satisfaction with colonoscopy, depending on whether sedation is used during the procedure or not. Patients will receive questionnaires before the procedure to assess the potential influence of patient criteria and after the procedure to assess satisfaction-scores and pain-scores. A validated satisfaction score (Schoen et al.) will be used for the primary outcome. As secondary parameters, pain- and sedation-scores will be assessed by the validated NAPCOMS score, as well as procedural quality indicators. The study will assess, whether adequate selection in regards to risk factors for sedated or unsedated colonoscopy, leads to similar satisfaction-scores within both groups.
