Impacting cost and appropriateness of stress ulcer prophylaxis at a university medical center.
OBJECTIVE
To determine the appropriateness and medication cost of stress ulcer prophylaxis before and after a targeted educational intervention.


METHODS
In the preintervention cohort (phase 1), 264 patients were evaluated over 2 months, using stress ulcer prophylaxis guidelines developed by a comprehensive literature search. Targeted educational programs were subsequently used to inform trauma housestaff on appropriate usage of stress ulcer prophylaxis medications with emphasis on using sucralfate. The postintervention cohort (phase 2) involved concurrent evaluation of 279 patients. Length of inappropriate stress ulcer prophylaxis (i.e., did not meet approved guidelines) between phases was compared using a Student's t-test for independent samples (alpha = .05).


METHODS
A 365-bed university medical center.


METHODS
Patients admitted to any of the intensive care units and all patients who were placed on histamine-2-antagonists or sucralfate for stress ulcer prophylaxis.


METHODS
Educational intervention regarding appropriate stress ulcer prophylaxis directed at the trauma service.


RESULTS
Patient demographics in the two phases were similar and there was no difference in the number of patient risk factors for stress-induced bleeding. The mean length of inappropriate stress ulcer prophylaxis was 5.78 +/- 4.36 days in phase 1 and 4.66 +/- 3.10 days in phase 2 (p < .05). Eighty-nine patients in phase 1 received inappropriate stress ulcer prophylaxis for a drug cost of $2,272.00 (mean $25.53 +/- 25.52) compared with 90 patients in phase 2 with a drug cost of $1,417.00 (mean $15.75 +/- 13.06). Three patients in each phase had clinically important bleeding (hemodynamic compromise or transfusion); all were receiving ranitidine. The mean total cost (fixed and variable) of hospitalization was $69,288.00 and $74,709.00 for the three patients who bled in each phase compared with $19,850.00 and $15,812.00 for all patients admitted to the intensive care unit in phases 1 and 2, respectively. The mean length of hospital stay was 30.00 days and 29.33 days for the three patients who bled in each phase compared with 11.54 days and 10.27 days for all patients admitted to the intensive care unit in phases 1 and 2, respectively.


CONCLUSIONS
Cost savings are associated with more appropriate stress ulcer prophylaxis. Clinically important bleeding is uncommon but results in prolonged hospital stays and increased costs.
