The effect of a patient informative leaflet on chronic use of proton pump inhibitors in a primary care center: a randomized control trial.

BACKGROUND: Chronic non-medically indicated PPIs are highly prescribed worldwide. The long-term side effects of PPI must be wisely considered during an extended prescription duration. Our study purpose is to assess the impact of providing patients and physicians with educational guides on the rates of reducing or eliminating PPIs. DESIGN AND METHODS: A controlled study targeting adult patients with chronic PPI use was conducted in a family medicine center in Beirut. Block randomization was employed. Patients (n = 140) were equally divided into an intervention group consisting of a patient-oriented informative and motivational leaflet and a control group having the same follow-up without having the leaflet. All participants filled a questionnaire. All participants received a short phone call in 2 and 6 months. An e-mail clarifying the objective of this study was sent to all physicians and supplemented with a PPI deprescribing algorithm. RESULTS: At the 6-month follow-up, the rate of participants who talked to treating physicians about their PPI therapy was higher in the intervention group (p-value<0.0001), and the rate of participants who stepped down or off PPI was higher in the intervention group (p-value<0.0001). In participants who stepped down or off PPI, the reported breakthrough symptoms decreased over time (moderate: 24.2%, mild: 35.5%, and nil: 40.3% at 2-month follow-up; and moderate: 0%, mild: 55.4% and nil: 44.6% at 6-month follow-up; p-value<0.0001). CONCLUSION: A low-intensity, low-cost, and easily replicable intervention encouraged a significant number of long-term users of PPIs to reduce or stop these medications without causing significant breakthrough symptoms.
