Cost-effectiveness analysis of high-dose omeprazole infusion as adjuvant therapy to endoscopic treatment of bleeding peptic ulcer

Gastrointest Endosc. 2003 Feb;57(2):160-4. doi: 10.1067/mge.2003.74.


Background: Intravenous administration of proton pump inhibitors after endoscopic treatment of bleeding peptic ulcers has been shown to decrease the rate of recurrent bleeding and the need for subsequent surgery. Yet there is a relative lack of formal assessment of this practice. The aim of this study was to examine the cost-effectiveness of this therapy by using standard pharmacoeconomic methods.

Methods: The present study was performed in conjunction with a randomized controlled clinical trial that included 232 patients who received either omeprazole (80 mg intravenous bolus followed by infusion at 8 mg/hour for 72 hours) or placebo after hemostasis was achieved endoscopically. A cost-effectiveness analysis was performed to evaluate the different outcomes of the trial. All related direct medical costs were identified from patient records. Cost-effectiveness ratios were calculated.

Results: Analysis by the Kolmogorov-Smirnov test showed that the direct medical cost in the omeprazole group was lower than that for the placebo group. Cost-effectiveness ratios for omeprazole and placebo groups were, respectively, HK$ 28,764 (US$ 3688) and HK$ 36,992 (US$ 4743) in averting one episode of recurrent bleeding in one patient after initial hemostasis was achieved endoscopically.

Conclusions: Intravenous administration of high-dose omeprazole appears to be a cost-effective therapy in reducing the recurrence of bleeding and need for surgery in patients with active bleeding ulcer after initial hemostasis is obtained endoscopically.
