This case study describes a medical error that occurred in the intensive care unit. Two patients, Mr. Lucas and Mr. London, were admitted emergently and in critical condition. In the rush to fill orders, the pharmacy incorrectly labeled the IV bags, resulting in Mr. London receiving heparin instead of octreotide. As a result, the wrong drugs were administered to each patient. The pharmacy supervisor discovered the error after one patient had died. The case raises issues around patient safety, ensuring the right medications are given to the right patients, and preventing medical errors during busy times.
