Narrow Results Clear All
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.

Two cases in which thyroid function tests were ordered appropriately but not acted upon in a timely fashion illustrate the challenges of thyroid emergencies. The patient in Case #1 had a history of hyperthyroidism and noted not taking his medications for months, yet no one addressed his abnormal thyroid function tests until hospital day 3. He had thyroid storm. In Case #2, providers neglected to follow up on the patient's abnormal thyroid function tests, even though she was taking a medication with a known risk of thyroid toxicity. She had myxedema coma.

For an older patient presenting with upper back pain and faint bilateral crackles, physicians misinterpreted a negative sepsis screen as a negative infection screen and delayed antibiotic treatment for pneumonia. The patient developed worsened hypoxemia, hypotension, delirium, and progressive organ failure.

A woman was discharged with instructions to complete an antibiotic course for C. difficile. The same day, the microbiology laboratory notified the patient's nurse that her blood culture grew Listeria monocytogenes, a bacterium that can cause life-threatening infection. However, the result was not communicated to the medical team prior to discharge.
Scott D. Nelson, PharmD, MS; March 2017
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.
Joseph S. Alpert, MD; November 2012
A woman with new onset chest pain was admitted to the hospital. Although the computer readout of her electrocardiogram stated "***ACUTE MI***" at the top, the nursing assistant who performed the test placed it in the patient's bedside chart without notifying a nurse or physician. The patient was, in fact, having a myocardial infarction, whose treatment was delayed.
