What is known and objective: At present, studies on the usage of proton-pump inhibitors (PPIs) have universal significance. In clinical practice, PPIs are widely used to treat a variety of acid-related diseases, but they can be inappropriately prescribed, leading to increased medical costs and patient harm. The study comprehensively evaluated the clinical effects of a clinical pharmacist intervention on inappropriate PPI prescriptions in a tertiary general hospital hepatobiliary surgery ward.
Methods: A retrospective, single-centre intervention study covering the periods of July-December 2018 and July-December 2019 was conducted. In the intervention group, clinical pharmaceutical care was initiated by a clinical pharmacist in the hepatobiliary surgery ward. Outcomes, including the clinical pattern of PPI utilization, the rate of inappropriate PPI use and safety outcomes, were compared between the two periods.
Results and discussion: In total, 1150 patients were admitted to the hepatobiliary surgery ward in our hospital in the study periods. Of these, 717 patients met the inclusion criteria for this study, and 420 and 297 patients were included in the preintervention and post-intervention groups, respectively. The PPI utilization rates before and after the intervention were 82.0% and 55.0%, respectively. The rates of inappropriate PPI use before and after the intervention were 48.9 and 22.7 per 100 patient-days, respectively. Clinical safety outcomes were nearly identical between before and after the intervention, but patients treated with PPIs were more likely to experience nosocomial pneumonia (2.4% vs. 0.6%).
What is new and conclusion: The implementation of a clinical pharmacist intervention for PPI use decreased inappropriate PPI use during hospitalization without sacrificing clinical safety outcomes.
