Prospective Epidemiological Study Of Dyspepsia (Presto): Basic Considerations And Preliminary Results
DEUTSCHE MEDIZINISCHE WOCHENSCHRIFT(1999)
Abstract
Background and objective: Symptoms of dyspepsia (indigestion; upper abdominal discomfort) are one of the most frequent reasons for consulting a general practitioner or internist. Yet there are no up-to-date national data on the epidemiology and course of this symptom complex.Patients and methods: In an open, prospective, multicentre, epidemiological study (PRESTO) 3016 patients with the suspected diagnosis of "functional dyspepsia" (1228 males, 1788 females, mean age 50 +/- 15 years) were followed for 2 years by 983 physicians in private practice (general practitioners or specialists in internal medicine). Patients with proven gastrooesophageal reflux or peptic ulcer were excluded. Treatment was at the discretion of the physician. Patients were seen after one month (if under treatment) and then at 6, 12, 18 and 24 months. In addition to personal data, (1)symptoms, diagnosis and treatment of the dyspepsia, (2) socioeconomic aspects and (3) any limitations and the quality of life of each patient were recorded in a standard manner.Results: At the first interim analysis more than half the patients judged there situation to be one of "chronic stress" or having to cope with a stressful event; nearly 50% thought this to be the cause of the symptoms. Concomitant illnesses were present in 63% of patients. Oesophagogastroduodenoscopy with subsequent medication was performed in 20.6%, a trial of medication (usually drugs stimulating gastric motility) in 65%. No medication was initially given to 14.4% of patients. The most common symptoms were feeling of fullness (92.9%, epigastric pressure sensation (91.5%) and flatulence (87.4%).Conclusion: These preliminary results indicate that a large epidemiological study can be performed by general practitioners and has advantages over the more usual method of enquiry by telephone. Dyspepsia exerts an unusually high degree of stress and results in considerable demands on medical facilities.
