Intravenous pantoprazole utilization in a level 1 trauma center

In recent years there has been a rapid increase in the use of proton pump inhibitors. Our institution has recently had several shortages of IV pantoprazole, each lasting 7-10 days. The purpose of our study was to evaluate in-patient usage of IV pantoprazole. We hypothesized that hospitalized patients with upper gastrointestinal bleeding (GIB) or risk for stress ulcers inappropriately received IV pantoprazole based on current literature.

This was a retrospective study of 165 consecutive in-patients identified as receiving pantoprazole from December 2004 to March 2005. Only patients receiving IV pantoprazole were included (n = 78). Data collected included demographics, indication and dosing of pantoprazole, admitting team (surgery vs. medicine), and risk factors for stress ulcers.

Our study population had a mean age of 54 +/- 17 years and 62% were male. Overall, 45% (35/78) of patients receiving IV pantoprazole had an appropriate indication, and 19% (15/78) received the correct dose. Of the 78 patients, 43 (55%) were treated with pantoprazole for stress ulcer prophylaxis (SUP), and 35 (45%) patients were treated for GIB. We found that none of the 43 patients treated for SUP had an appropriate indication for pantoprazole, but all of the patients with GIB (35) had an appropriate indication. Of the 35 patients treated for GIB with pantoprazole, only 40% (14/35) received the correct dose. In all cases of incorrect dosing, the patients were underdosed.

Pantoprazole is not being prescribed appropriately for stress ulcer prophylaxis in our patient population. Even in patients appropriately receiving pantoprazole the majority were prescribed an incorrect dose. Appropriate indications and dosing of pantoprazole could eliminate the shortages seen at our institution.
