Study of Acid-related Disorders: Real-world Physician and Patient Perspectives on Burden of Helicobacter pylori Infection.

ABSTRACT

Background and Aims: Helicobacter pylori eradication rates have declined as antibiotic resistance rates have increased. In addition, adherence to treatment guidelines is suboptimal. It is therefore important that contemporary, real-world evidence of diagnostic and treatment patterns is explored and compared with evidence-based guidelines. The Study of Acid-Related Disorders investigated unmet needs among patients with H pylori infection and past or current dyspepsia. Methods: Gastroenterologists (GIs) and family physicians (FPs) or general practitioners (GPs) treating patients with H pylori infection and past or current dyspepsia completed a physician survey and invited patients to complete a patient survey; data were also extracted from the medical records of enrolled patients. Results: Two hundred fifty-one physicians and 77 patients were enrolled. A total of 19.5% of patients were diagnosed by serology, whereas the urea breath test was used by 6.5% of GIs and 50.0% of FPs or GPs. A total of 68.6% of GIs and 79.8% of FPs or GPs selected clarithromycin, amoxicillin, and proton pump inhibitor triple therapy as their ideal first-line treatment. Physicians reported that 52.9% of patients experienced dyspepsia daily. A total of 46.8% of patients believed that complete resolution of dyspepsia would indicate effective treatment. As their treatment goal, 69.3% of physicians selected improvement in overall symptoms, whereas 92.2% of patients specified improvement in dyspepsia. Only 28.7% of physicians were satisfied with current treatment options. A total of 59.7% of patients took all of their prescribed medicine(s). A total of 59.7% of patients would prefer to take fewer pills; 45.5% would prefer convenience packs. Conclusion: This study reveals a lack of adherence to current H pylori guidelines for diagnosis, testing, and treatment. New treatment options that are more efficacious and simpler for patients to adhere to are needed.
