Robert E. O'Connor, MD, MPH; March 2018
Emergency medical service (EMS) providers obtained an electrocardiogram (ECG) in a woman who had developed severe chest pressure at home. The ECG revealed an ST-elevation myocardial infarction (STEMI). Unfortunately, the ECG failed to transmit to the emergency department (ED) while EMS was en route, so a "Code STEMI" was not activated. Unaware of the original ECG results, ED clinicians obtained a repeat ECG that did not demonstrate the earlier ST segment elevations, and the patient was admitted to the telemetry unit for monitoring overnight. The next morning, lab results revealed an elevated troponin level and another ECG demonstrated she had a large heart attack the previous day. Although the patient was rushed to the cardiac catheterization laboratory, the delay in treatment led to significant loss of cardiac function.

Although meningitis and neurosyphilis were ruled out for a woman presenting with a headache and blurry vision, blood tests returned indicating latent (inactive) syphilis. Due to a history of penicillin allergy, the patient was sent for testing for penicillin sensitivity, which was negative. The allergist placed orders for neurosyphilis treatment—a far higher penicillin dose than needed to treat latent syphilis, and a treatment regimen that would have required hospitalization. Upon review, the pharmacist saw that neurosyphilis had been ruled out, contacted the allergist, and the treatment plan was corrected.
