OPINIONS IN DENMARK ON THE CAUSES OF PEPTIC-ULCER DISEASE - A SURVEY AMONG DANISH PHYSICIANS AND PATIENTS

The aim of the study was to investigate opinions among Danish patients and physicians on causes of peptic ulcer disease. Fifty-nine patients with an ulcer history and 77 physicians with a special interest in gastroenterology participated. They were given a questionnaire listing 16 possible causes of peptic ulcer and indicated for each whether they believed it was a contributory cause of the disease. The patients stated 0-10 causes each (median, 4), and the physicians 3-12 causes (median, 6) (p < 0.01). Younger physicians stated more causes than did the older ones (p < 0.01), and female physicians stated more causes than did their male colleagues (p < 0.01). Seventy-five per cent of the patients indicated that psychologic factors, such as grief, anxiety, and stress, were contributory causes of peptic ulcer disease, whereas only around 40% believed that coffee/tea, alcohol, smoking, side effects of medicine, and working conditions played a causal role. Around 95% of the physicians indicated that medical drugs and smoking were contributory causes of peptic ulcer disease, and around 80% that alcohol and psychologic factors were so. Only 30-40% of the physicians believed that coffee/tea, food habits, infection, and working conditions could play a causal role in ulcer disease. It is concluded that the opinion on causal agents in peptic ulcer disease differ considerably among both patients and physicians. Opinions on causes of diseases may influence the way we treat and advise our patients, and attempts should thus be made to unify our knowledge and interpretations of causes of diseases to reach more solid ground in counselling our patients.
