INTRODUCTION: Upper gastrointestinal stress ulcer formation is a potential risk for critically ill hospitalized patients. Due to this, SUP is an important preventative measure for at risk patients. Stress ulcer medications such as PPIs and H2 blockers do come with potential side effects.1,2 A widely accepted guideline was written by the American Society of Health System Pharmacists which along with similar variations continue to be used today.3,4 One such guideline has been implemented within the Ascension Health System (Figure 1). Despite guidelines, inappropriate administration continues to be a common problem. Studies show rates of inappropriate administration anywhere from 20 to 70 percent.5–9 A discrepancy in knowledge from providers leads to inappropriate prescribing of SUP medications. Administration of these laminated cards will improve appropriate administration of the medications. METHODS: Laminated cards were dispersed to fit on ID badges of IM and FP residents which following the Ascension SUP guidelines. Data was collected on all patients admitted under the core faculty of an IM or FP attending between 7/1/18–9/30/18 and 11/1/18–1/31/19. 10/1/19-10/31/19 constituted the run-in period. Patients were excluded if they had active diagnoses of GERD, PUD, H. Pylori. Eligible patients' charts were reviewed at random by using an online number generator. The A&P section of the H&P note was reviewed to determine if SUP was was appropriately administered, appropriately held, inappropriately administered, or inappropriately held. Any discrepancies were reviewed by the principal investigator. A t-test was performed to determine if statistical significance was achieved. RESULTS: There were 124 and 115 patients in the pre and post-intervention period respectively. There was an overall improvement of 5.64% (P = 0.21) after distribution of cards (Figure 1). Inappropriately given SUP use improved by 5.01% (P = 0.22). Inappropriately held SUP use improved by 0.61% (P = 0.78). CONCLUSION: Administration of cards improved appropriate prescribing. The cards provided a resource to aid in enhancing knowledge and on-the-go decision making. The availability of implementing these guidelines or similar such protocols using EMR may be more effective in reaching a wider audience of physicians and provide a consistent effect on prescribing habits.
