ABSTRACT
BACKGROUND: Although upper gastrointestinal (UGI) endoscopy is highly sensitive for the detection of esophago-gastroduodenal lesions, pain and discomfort during the procedure cause examinees to experience stress and anxiety. Moreover, there have been only a few studies on relief of pain and discomfort during UGI endoscopy through preparatory interventions. Therefore, the aim of this study was to investigate the relationship between a preparatory education program and the discomfort and retching experienced by examinees during endoscopy. METHODS: A total of 306 examinees who visited a health promotion center and underwent non-sedated endoscopy from May 13 to July 3, 2009 were included in this study. After they were assigned to experimental (n = 154) and control groups (n = 152), their discomfort and retching were measured with a visual analogue scale. The preparatory education program consisted of cognitive intervention, behavioral intervention and information. RESULTS: The preparatory education program relieved discomfort during endoscopy in male subjects, in subjects aged 60 and over, or in subjects with previous endoscopic experience with statistical significance (P < 0.05). It also relieved retching during endoscopy in subjects aged 60 and over with statistical significance (P = 0.023). Multiple logistic regression analysis showed that the preparatory education program significantly relieved the discomfort of examinees during endoscopy (P = 0.028). CONCLUSION: We found that the preparatory education program used in this study could significantly relieve the discomfort caused by endoscopy, particularly in subjects aged 60 and over, or in male subjects with a high incidence of stomach cancer in Korea.
