Background: Due to the risk of development of stress ulcers in intensive care unit (ICU) patients, pharmacologic prophylaxis is often utilized. However, some literature describes the use of enteral nutrition instead as stress ulcer prophylaxis. Methods: The purpose of this study is to determine if enteral nutrition is similar to pharmacologic stress ulcer prophylaxis (SUP) with enteral nutrition for reduction of gastrointestinal (GI) bleeding, perforation, or ulceration in ICU patients. This was a retrospective, single-center cohort study that took place at an academic medical center. Adult ICU patients receiving enteral nutrition who had a risk factor for stress-related mucosal damage were included. The primary outcome was the incidence of GI bleeding, perforation, or ulcer formation. Results: Overall, 167 patients were included in the study, 147 in the pharmacologic prophylaxis plus EN group (PPEN) and 20 in the enteral therapy only (EN) group. Of 167 patients included, 22 patients (21 in the PPEN group and 1 in the EN group) developed a primary outcome of GI bleeding, perforation, or ulceration (14.3% vs 5%, P = .4781). Patients in the PPEN group had a higher incidence of pneumonia (42.2% vs 15%, P = .0194), but no difference was seen between groups when patients with pneumonia present on admission were excluded (20.6% vs 10.5%, P = .5254). Conclusion: In this small cohort of patients, enteral nutrition alone is as effective as pharmacologic therapy in addition to enteral nutrition for the reduction of stress-related GI bleeding, perforation, and ulceration.
