Health-related anxiety and the effect of open-access endoscopy in US patients with dyspepsia

Background: The role of endoscopy in dyspepsia is the subject of debate. The detection of lesions is infrequent, but patients may benefit from the knowledge that the examination is normal. We sought to determine the prevalence of health-related anxiety in dyspeptic patients referred for open-access endoscopy and to investigate the effect of endoscopy on health-related anxiety. Methods: Consecutive patients referred for open-access endoscopy from primary care were studied using a validated questionnaire for health-related anxiety before and after endoscopy, at 1 month and 6 months. Symptoms were assessed using a validated questionnaire at 1 and 6 months. Results: One hundred and nine patients were studied (69 women and 40 men; mean age, 49 +/- 15 years). Thirty-six of the 109 patients (33%) had high anxiety scores at baseline (mean score, 41 +/- 1), which decreased after endoscopy to 35 +/- 1 (P < 0.05). The changes persisted at 1 month (33 +/- 1) and 6 months (33 +/- 1). Endoscopic findings were as follows: normal examination, 120; erosive oesophagitis, 11 (Grade A); erosive duodenitis (all Helicobacter pylori -negative), 6. Scales for preoccupation with health and fear of illness and death showed significant improvement after endoscopy, and the effects were preserved for 6 months. Anxiety scores in our population were substantially higher than in a corresponding UK population. Conclusions: Health-related anxiety is common in dyspeptic patients referred for endoscopy. Endoscopy decreases the preoccupation with health and fear of illness and death in patients with severe anxiety, and the effects persist for 6 months.
