paragraph: Pharmacist-managed Helicobacter pylori clinic. A pharmacist-managed Helicobacter pylori assessment clinic for ambulatory patients is described. The pharmacy service at a 400-bed Veterans Affairs Medical Center established a pharmacist-managed clinic to assess patients who were receiving long-term acid-suppressive medications (histamine H2-receptor antagonists, sucralfate, or omeprazole). Patients with active ulcer disease and those receiving ulcer prophylaxis are screened for the presence of H. pylori. Those who test positive are treated with combinations of the following agents : omeprazole , clarithromycin , amoxicillin , tetracycline , and metronidazole . The pharmacist also may adjust or discontinue acid-suppressive drug regimens. The pharmacist is responsible for ordering all appropriate laboratory tests, monitoring patients for adverse effects, collecting data on patient outcomes, and providing patient education. The clinic provides opportunities for pharmacists to study the clinical effectiveness and pharmacoeconomics of various regimens for treating H. pylori-associated disease and for pharmacy students and residents to interact with patients. As of fall 1994, 20 patients had been evaluated at the clinic: 12 tested positive for H. pylori and were treated with antimicrobials and all were pain-free without medication at the end of treatment. An H. pylori assessment clinic enabled pharmacists to assume a primary care role, document improvement in patient outcomes, and study the effectiveness of various antimicrobial regimens.
