Abstract

Background: Many symptomatic patients take proton pump inhibitors or histamine-2 blockers for years and those without gastro-oesophageal reflux disease might benefit from Helicobacter pylori eradication. Aim: To increase testing and treatment of H. pylori and reduce chronic use of proton pump inhibitors and histamine-2 blockers. Methods: We conducted a three-armed controlled trial in 14 managed care practices. We included adults who used proton pump inhibitors or histamine-2 blockers for >1 year and excluded those with gastro-oesophageal reflux disease or previous endoscopy. We compared usual care (n = 312 patients from 6 practices) to low-intensity (n = 147 from 3 practices) and high-in tensity (n = 122 from 5 practices) interventions. Low-intensity intervention consisted of guidelines, patient-lists, and a 'toolkit'; high-intensity intervention added academic group detailing by a gastroenterologist with reinforcement by pharmacists. Results: Compared with usual care, the high-intensity intervention increased H. pylori test-ordering (29% versus 9% at 12 months, P = 0.02). About half (23 of 58) of patients tested positive and 22 received eradication treatments. The high-intensity intervention decreased proton pump inhibitor use by 9% per year (P = 0.028), but did not alter histamine-2 blocker use. The low intensity intervention was ineffective. Conclusions: Providing guidelines, patient-lists, and toolkits was no better than usual care. Adding group detailing and pharmacist reinforcements led to improvements in H. pylori management and decreases in proton pump inhibitor use.
