Patient attitudes to sedation for diagnostic upper endoscopy.

The presumed need for sedation in upper gastrointestinal endoscopy differs widely between countries and between endoscopists. Very little is known about patient attitudes and the factors that influence patient discomfort. We investigated all ambulatory patients scheduled for diagnostic upper GI endoscopy during a 4-month period (n = 1169) for their attitudes to sedation. One week before the examination they were asked whether they wanted sedation in addition to topical throat anesthesia. A brief description of the endoscopic procedure was given together with an explanation of presumed advantages and disadvantages of sedation. Only 399 patients (34.1%) wanted sedation. The two groups of patients were comparable as to age, gender, and previous experience of endoscopy. Of the 399 patients wanting sedative medication 54.2% were afraid of the diagnosis and 45.8% of the procedure. Male sex and young age were associated with a lower rate of preferring sedation. Patient discomfort during endoscopy was negatively correlated with age (r = -0.309; p = 0.000). Patients who had had more than one previous endoscopy had less discomfort than those without endoscopy experience (p = 0.0069). Men had less discomfort than women (p = 0.0014). The vast majority of our patients preferred 'a normal afternoon to endoscopy sedation'. Young women not previously endoscoped potentially benefit most from sedation.
