Efficacy of a Multi-faceted Intervention to Deprescribe Proton Pump Inhibitors (PPI) in Primary Care: a Population-based, Pragmatic, Cluster-randomized Controlled Trial.

Deprescribing is defined as "the process of withdrawal of an inappropriate medication, supervised by a health care professional with the goal of managing the polypharmacy and improving outcomes". Inappropriate use of proton pump inhibitors (PPI) is associated with severe adverse drug reactions and a major economic impact. Deprescribing should be considered when inappropriate prescription of PPI is identified. DeprescrIPP is a pragmatic population-based cluster-randomized trial conducted in primary care. It will assess the efficacy and effectiveness of a multi-faceted intervention (on patients and general practitioners) to deprescribe PPI.
