Impact of clinical pharmacist interventions on inappropriate prophylactic acid suppressant use in hepatobiliary surgical patients undergoing elective operations.

Objective: To evaluate the impact and cost-benefit of clinical pharmacist interventions on inappropriate use of prophylactic acid suppressant in hepatobiliary surgical patients in a Chinese tertiary hospital. Methods: A retro-prospective intervention study of patients undergoing elective operations was performed in the Department of Hepatobiliary Surgery of the Affiliated Hospital of Southwest Medical University. Patients admitted from October to December 2015 and from October to December 2016, served as the pre-intervention and the post-intervention group, respectively. Clinical pharmacist interventions in the post-intervention group included real-time monitoring medical records and recommending that surgeons prescribe prophylactic acid suppressants according to the criteria established by the hospital administration. Then, the clinical outcomes of post-intervention group were compared with the pre-intervention group which lacked pharmacist interventions. In addition, cost-benefit analysis was conducted to determine the economic effects of implementing the clinical pharmacist interventions in acid suppressant prophylaxis in perioperative period. Results: Clinical pharmacist interventions significantly decreased the rate of the use of no indications for prophylactic acid suppressant and of the cases of inappropriate drug selection, dose, route, replacement and prolonged duration of prophylaxis (P < 0.05 or P < 0.001), resulting in significant increase by 10.65% in the percentage of cases adhering to all the criteria (P < 0.001). Moreover, significant reductions were found in the average usage quantity (P<0.001), mean cost (P = 0.03) and mean duration (P < 0.001) of prophylaxis acid suppressant. The ratio of the mean cost savings for acid suppressants to the mean cost of pharmacist time was 13.61:1. Conclusion: The clinical pharmacist’s real-time interventions facilitated the rational use of prophylactic acid suppressant and resulted in favorable economic outcomes in hepatobiliary surgery.
