Background Acid suppression medications are routinely used in general intensive care unit patients for prevention of stress‐related gastric mucosal bleeding. Their use has been extrapolated to include elective postoperative cardiac surgical patients. The evidence for their use in this group of patients remains inconclusive (Shin and Abah, Interact Cardiovasc Thorac Surg, 2012; 14: 622‐8). Aim To audit the use of acid suppression therapy in postoperative cardiac surgical patients as inpatients and after discharge, and ascertain whether these patients experienced postoperative gastrointestinal bleeding. Method A retrospective chart review was undertaken, focusing on cases of cardiac surgical intensive care patients to investigate the use of stress ulcer prophylaxis and the occurrence of post‐surgical gastrointestinal bleeding. The continuation of therapy after discharge was also audited. Results The cases of 78 patients were included in the audit: all received stress ulcer prophylaxis, and no patients experienced gastrointestinal bleeding postoperatively. In all, 27% of these patients were dispensed acid suppression therapy without a valid indication at the time of discharge. Conclusions It cannot be conclusively determined if the absence of postoperative gastrointestinal bleeding was due to the administration of prophylaxis. An alternative explanation is that stress ulcers were not likely to occur in this cohort of patients. Despite not having any indication for continuation of acid suppression, 20 patients were discharged with these medications.
