Standardize Communication With General Practitioner & Patient for Improved Eradication of Helicobacter Pylori

Patients who test Helicobacter pylori positive, are treated with antibiotics. However, due to a number of factors (such as unknown treatment compliance, no standardized follow-up, ...), a relative low eradication-percentage was reported. Therefore, the investigators want to measure the anticipated improvement in eradication-percentage due to the standardized treatment schedules (1st line, 2nd line and further) and the optimized communication with the general practitioner and patients.
