[Experiences with a computer-assisted concept for patient education in gastroenterologic endoscopy].

The purpose of this study was the assessment of the effect of audio-visual information, based on computer technology, on the reduction of anxiety in patients referred for gastrointestinal endoscopies. 72 of 100 consecutive patients (38 females, 34 males; median age 49 years [13-80 years]) were willing to study the available computer program for pre-diagnostic information. They were questioned regarding their anxiety about the forthcoming examination, and the acceptance and handling of the computer system. Anxiety levels were measured by a Visual Analogue Scale directly before endoscopy and after the examination. Nearly two thirds of the patients (60%) stated, that their anxiety level was reduced by watching the computer program. 96% of the patients felt comfortable with this type of information. Thus, the pre-procedure information demonstrated by the computer (backgrounds, instruments and procedural technics) relieves in a surprisingly large percentage of patients fears and worries about endoscopic procedures.
