Background: The prescriptions of proton pump inhibitors (PPIs) have raised concern due to both huge increase in medical expenditure and the possible long-term adverse events caused by them; therefore, an approach to taper off the irrational use of PPIs by patients is clinically warranted. The aim of this study was to evaluate the impact of pharmaceutical interventions on the rational use of PPIs.
Patients and methods: A single-center, pre- to post-intervention study (pharmaceutical interventions group and control group) was performed in a Chinese hospital. Pharmaceutical interventions were performed in the post-intervention group, including educative group activities, real-time monitoring of clinical records and making recommendations to doctors on PPI prescriptions based on the criteria set at the beginning of the study. The number of patients with rational indication, the accuracy rate of administration route, the duration of therapy and the changes in total PPI costs, mean PPI costs, mean total drug costs and mean hospitalization costs were the main outcome measures.
Results: A total of 285 patients were included in the study. After 6 months of interventions, significant improvements in the number of patients with rational indication were found (96.5% in the pharmaceutical interventions group vs 71.8% in the control group, P<0.01). The accuracy rate of administration route was increased (99.3% vs 73.2%, P<0.05), while the duration of therapy was decreased (7.9±0.5 vs 14.3±0.8, P<0.01). Pharmaceutical interventions led to significant reductions in mean PPIs costs, mean total drug costs and mean hospitalization costs (P<0.001).
Conclusion: This study provides important evidence on the beneficial effect of pharmaceutical interventions on enhancing the rational use of PPIs and substantial cost saving by increasing the number of patients with rational indication and reducing the risk for long-term adverse events.
