Study objectives1. To determine the cost-effectiveness of an H. pylori 'test and trust' strategy compared with initial acid suppression for the initial management of dyspensia in primary care
2. To determine the influence of selected patients on the basis of predominant heartburn or epigastic pain
3. To determine the performance of the H. pylori stool antigen (HpSA) test for H. pylori compared with a C13 Urea breath test for confirming H. pylori eradication in primary care

Please note that the target number of participants was added as of 06/03/2008.
Ethics approval(s)Not provided at time of registration
Health condition(s) or problem(s) studiedDyspepsia in primary care
InterventionAll patients - will receive omeprazole 20mg once daily.

Study Group - C13 Urea breath test for H. pylori, using a test kit performed by the practice nurse. Patients testing positive will be offered H. pylori eradication with clarithromycin 250 mg twice daily and metronidazole 400 mg twice daily in addition to omeprazole. Patients testing negative will continue PPI (omeprazole).

Control Group - Patients will continue 4/52 PPI (omeprazole).

After four weeks patient management will be at the discretion of the general practitioner (GP). Patients receiving H. pylori eradication will be contacted by research staff and asked to attend for a follow-up breath test and produce a stool sample (for the stool antigen test) nine weeks after entry.
Follow-up will be by postal questionnaire at 12 weeks, interview at one year and a GP notes review (conducted by research staff).
Intervention typeDrug
Pharmaceutical study type(s)
PhaseNot Specified
Drug / device / biological / vaccine name(s)omeprazole, clarithromycin, metronidazole
Primary outcome measure1. Effects measured as absolute risk reduction for dyspeptic symptoms measured by the Short Form Leeds Dyspepsia score, a validated community-based measure that also includes a question on 'predominant symptoms'.
2. Health service related dyspepsia costs as determined by application of national reference costs to individual units of resource consumption (prescribing, consultations, interventions and investigations).
Secondary outcome measures1. Quality of life using Euro-QoL instrument (EQ-5D).
2. Patient satisfaction using the consultations Satisfaction Score (subscales one and two, general and professional care)
3. Performance of HpSA test
