Title: Stress Ulcer Prophylaxis in the Intensive Care Unit (SUP-ICU)
Brief Summary: Stress ulcer prophylaxis (SUP) is standard of care in the intensive care unit (ICU), however the quantity and quality of evidence is low and potential harm has been reported.

The aim of the SUP-ICU trial is to asses the overall benefits and harms of SUP with proton pump inhibitor in adult critically ill patients in the ICU.
