In 2003, British Columbia’s PharmaCare programme implemented a drug reimbursement policy called Therapeutic Substitution, which required patients with acid-related diseases, primarily gastro-oesophageal reflux disease (GERD), to make a medically unnecessary switch from their prescribed proton pump inhibitor (PPI) to the cheapest available brand name PPI (Pariet, rabeprazole sodium), comprising a different (nongeneric) chemical. This study evaluates the independent effects of PPI Therapeutic Substitution on individual healthcare utilization among those complying with the policy.
