Outcome Measures
Primary Outcomes (1)
Patient Assessment of Pain Experienced During Colonoscopy
The proportion of patients reporting "no pain" when examined with prototype or standard colonoscope, respectively. Pain experienced was assessed by the patient in a questionnaire to be filled in at home on the day after the examination and mailed in a pre-paid envelope to a national quality register (Gastronet).
