BACKGROUND: Quadruple therapy using a single capsule formulation of bismuth, metronidazole and tetracycline (BMT; Pylera®), associated with omeprazole for the eradication of Helicobacter pylori, represents the reintroduction of bismuth in France after 40 years. OBJECTIVE: To describe the real-life patterns of use of BMT following a request from the French health authorities. METHODS: Patients with a first BMT dispensing (index date, ID), with one year of data before and after ID, were identified in the French nationwide claims database 1/97 sample. Misuse of BMT was defined as dispensing>1 pack of BMT at ID or absence of a diagnostic test in the preceding year. RESULTS: In total, 540 patients were included. Prescribers were gastroenterologists (n=243; 45%) and general practitioners (n=160; 30%). A proton pump inhibitor was co-dispensed to 504 patients (96%). Ten patients (2%) had contraindications to BMT. Fifty-nine patients (11%) met the misuse criteria: ten (2%) were dispensed>1 pack of BMT and 49 (9%) had not had a diagnostic test for H. pylori in the previous year. During follow-up, 27 patients (5%) required retreatment (treatment failure). CONCLUSION: In this real-life study, most patients were dispensed only one pack of BMT, consistent with recommendations. Misuse related principally to the absence of prior diagnostic test for H. pylori.Read less <
