The impact of pharmacist intervention on the intravenous-to-oral switch therapy of proton pump inhibitors in cardiovascular surgery

The prescriptions of proton pump inhibitors (PPIs) have been widely concerned due to both huge increase in medical costs and possible long-term adverse events (AEs) caused by the improper route of drug administration. The aim of this study was to assess the effectiveness of pharmacist interventions on the clinical outcome and safety of switching from intravenous (IV) to oral PPIs therapy.A retrospective, single-center, pre- intervention (early -stage)- and intervention (later -stage) study was performed in a Chinese hospital.A total of 1736 patients were included in the study. After 12 months of interventions, significant improvements in the number of rational IV to oral switch in patients with oral switch indications were found. The median duration of oral therapy was increased, while the duration of PPIs therapy was decreased. Pharmacist interventions led to significant reductions in mean PPI costs, mean total drug costs, mean hospitalization costs, and the risk for long-term adverse events.This study provides important evidence on the beneficial effect of pharmacist interventions on promoting an optimal IV to oral switch of PPIs and substantial cost saving by shortening the duration of IV PPIs therapy and reducing the risk for long-term AEs.
