Design Randomised controlled trial.
Setting 80 general practices in the United Kingdom.
Participants 699 patients aged 18-65 who presented to their general practitioner with epigastric pain, heartburn, or both without "alarm symptoms" for malignancy.
Intervention H pylori 13C urea breath test plus one week of eradication treatment if positive or proton pump inhibitor alone; subsequent management at general practitioners discretion.
Main outcome measures Cost effectiveness in cost per quality adjusted life year (QALY) (EQ-5D) and effect on dyspeptic symptoms at one year measured with short form Leeds dyspepsia questionnaire.
Results 343 patients were randomised to testing for H pylori, and 100 were positive. The successful eradication rate was 78%. 356 patients received proton pump inhibitor for 28 days. At 12 months no significant differences existed between the two groups in QALYs, costs, or dyspeptic symptoms. Minor reductions in costly resource use over the year in the test and treat group "paid back" the initial cost of the intervention.
Conclusions Test and treat and acid suppression are equally cost effective in the initial management of dyspepsia. Empirical acid suppression is an appropriate initial strategy. As costs are similar overall, general practitioners should discuss with patients at which point to consider H pylori testing.
