C. Craig Blackmore, MD, MPH; March 2019
A woman with multiple myeloma required placement of a central venous catheter for apheresis. The outpatient oncologist intended to order a nontunneled catheter via computerized provider order entry but accidentally ordered a tunneled catheter. The interventional radiologist thought the order was unusual but didn't contact the oncologist. A tunneled catheter was placed without complications. When the patient presented for apheresis, providers recognized the wrong catheter had been placed, and the patient underwent an additional procedure.
Rommel Sagana, MD, and Robert C. Hyzy, MD; March 2019
Following an elective carotid endarterectomy, an elderly woman was extubated in the operating room (OR) and brought to the recovery area. She soon developed respiratory distress necessitating urgent reintubation, which required multiple attempts. She was found to have an expanding neck hematoma, which was drained safely in the OR. Later that day after a half hour weaning trial, the respiratory therapist extubated the patient without checking for a cuff leak. Within 15 minutes, she developed acute shortness of breath and stridor, which rapidly progressed to hypoxemic respiratory failure. Urgent reintubation was difficult because her vocal cords were edematous.

Stephanie Mueller, MD, MPH; February 2019
To transfer a man with possible sepsis to a hospital with subspecialty and critical care, a physician was unaware of a formal protocol and called a colleague at the academic medical center. The colleague secured a bed, and the patient was sent over. However, neither clinical data nor the details of the patient's current condition were transmitted to the hospital's transfer center, and the receiving physician booked a general ward bed rather than an ICU bed. When the patient arrived, his mentation was altered and breathing was rapid. The nurse called the rapid response team, but the patient went into cardiac arrest.
Robert Chang, MD, and Scott Flanders, MD; February 2019
A woman was admitted to a hospital's telemetry floor for management of uncontrolled hypertension and palpitations. On the first hospital day, she complained of right arm numbness and weakness and had new difficulty answering questions. The nurse called the hospitalist and relayed the arm symptoms, but not the word-finding difficulty. The hospitalist asked the nurse to call for a neurology consultation. Four hours later, the patient's weakness had progressed; she was now completely unable to move her right arm. At that point, neither the hospitalist nor the neurology consultant had evaluated the patient in person. A stat head CT revealed a large ischemic stroke.

Ifedayo Kuye, MD, MBA, and Chanu Rhee, MD, MPH; October 2018
Admitted with generalized weakness, nausea, and low blood pressure, an elderly man was given IV fluids and broad spectrum antibiotics. Laboratory test results revealed a mildly elevated white count, acute kidney injury, and elevated liver function tests. The patient was admitted to the medical ICU with a presumed diagnosis of septic shock. His blood pressure continued to trend downward. While reviewing the emergency department test results, the ICU resident noticed the patient's troponin level was markedly elevated and his initial ECG revealed T-wave inversions. A repeat ECG in the ICU showed obvious ST segment elevations, diagnostic of an acute myocardial infarction. The resident realized that the patient's low blood pressure was likely due to the myocardial infarction, not septic shock. He underwent urgent cardiac catheterization and was found to have complete occlusion of the right coronary artery, for which a stent was placed.
Thomas J. Balcezak, MD, MPH, and Ohm Deshpande, MD; October 2018
An elderly man presented to the emergency department (ED) with decreased oral intake, fevers, confusion, and falling urine output. Laboratory test results revealed acute-on-chronic renal failure, and an ECG showed tall T waves, potentially a sign of severe hyperkalemia and a precursor of a dangerous arrhythmia. The ED physician initiated treatment for hyperkalemia, and the on-call intensivist and nephrologist agreed the patient needed urgent hemodialysis. Although they planned to place a hemodialysis catheter and start dialysis as soon as possible, the ICU was full and the patient was forced to "board" in the ED. On arrival to the ICU, 5 hours after the initial labs, the patient was hypotensive and unarousable. The patient went into cardiac arrest, was intubated, and received urgent treatment for hyperkalemia. The nephrologist arrived and was surprised the hemodialysis had not been started. The dialysis nurse had been told to start the dialysis after the patient arrived in the ICU but was unaware of the urgency of the situation.

David J. Lucier, MD, MBA, MPH, and Jeffrey L. Greenwald, MD; September 2018
An older woman with lung cancer that had metastasized to the brain was admitted to the hospital and found to have Pneumocystis jiroveci pneumonia (PJP pneumonia), invasive pulmonary aspergillus, diffuse myopathy, and gastrointestinal bleeding. Medication reconciliation revealed that she had been prescribed a high dose of dexamethasone to reduce the brain swelling associated with the cancer. Although the intention had been to taper the steroids after she received radiotherapy for her brain metastases, the corticosteroids were never tapered, and she continued to take high-dose steroids for more than 2 months. Physicians believed that all of her acute issues were a result of the mistakenly high dose of the steroids.
Jason Bergsbaken, PharmD; September 2018
A woman with cancer was admitted to begin a chemotherapy cycle of IV etoposide (daily for 3 days) and IV cisplatin (single dose). At the hospital's cancer center satellite pharmacy, the pharmacist entered the order into the computer and prepared the first dose of the medications. While transcribing the order, the pharmacist inadvertently switched the duration of therapy for the two agents. The transposition did not affect the patient's first day of therapy. The second day fell on a Saturday, when the satellite pharmacy was closed; a different pharmacist who did not have access to the original chemotherapy order prepared the therapy order. Cisplatin was labeled, dispensed, and reached the bedside. The nurse bypassed the double-check policy for verifying the order prior to administration, and the patient received the second dose of cisplatin instead of the intended dose of etoposide.

Jeffrey Jim, MD, MPHS; August 2018
An older man with multiple medical conditions and an extensive smoking history was admitted to the hospital with worsening shortness of breath. He underwent transthoracic echocardiogram, which demonstrated severe aortic stenosis. The cardiology team recommended cardiac catheterization, but the interventional cardiologist could not advance the catheter and an aortogram revealed an abdominal aortic aneurysm (AAA) measuring 9 cm in diameter. Despite annual visits to his primary care physician, he had never undergone screening ultrasound to assess for presence of an AAA. The patient was sent emergently for surgical repair but had a complicated surgical course.

Resa E. Lewiss, MD; July 2018
After an emergency department (ED) physician interpreted results of a point-of-care ultrasound as showing stable low ejection fraction, some volume overload, and a mechanical mitral valve in place without regurgitation for a man with a history of congestive heart failure, end-stage renal disease, and mechanical mitral valve replacement who presented with shortness of breath, the patient was admitted with a presumed diagnosis of volume overload. Reassured by the ED physician's interpretation of the ultrasound, the hospitalist ordered no further cardiac testing. The patient underwent hemodialysis, felt better, and was discharged. Less than 12 hours later, the patient returned critically ill and in cardiogenic shock. An emergency transthoracic echocardiogram found a thrombosed mitral valve, which had led to acute mitral stenosis and cardiogenic shock.
Rita L. McGill, MD, MS; July 2018
Admitted to the hospital with an ulcer on his right foot, a man with diabetes and stage IV chronic kidney disease had an MRI concerning for osteomyelitis, and a bone biopsy showed chronic inflammation with cultures positive for methicillin-sensitive Staphylococcus aureus. To administer outpatient parenteral antimicrobial therapy, interventional radiology attempted to place a peripherally inserted central catheter (PICC) in the right brachial vein multiple times but failed. They then placed it in the left brachial vein. The patient completed 6 weeks of antibiotic therapy and wound care, and the PICC was removed. Five months later with worsening renal function and hyperphosphatemia, the patient required dialysis access, but he was not a candidate for arteriovenous fistula placement since the many venipuncture attempts during PICC placement resulted in poor vein quality.
Deborah Debono, PhD, RN, and Tracy Levett-Jones, PhD, RN; July 2018
A young adult with a progressive neurological disorder presented to an emergency department from a nursing home with a dislodged GJ tube. As a workaround to maintain patency when the GJ tube was dislodged, nursing home staff had inserted a Foley catheter into the ostomy, inflated the Foley bulb in the stomach, and tied the distal portion of the catheter in a loose knot. When the patient went to interventional radiology for new GJ tube placement, clinicians found no Foley but inserted a new GJ tube. Discharged to the nursing home, the patient was readmitted 2 days later with fever and increasing abdominal distention. An abdominal CT scan showed an obstructing foreign body in the small bowel.

A. Clinton MacKinney, MD, MS, and Nicholas M. Mohr, MD, MS; June 2018
After presenting to a rural emergency department with chest pain, a man with a history of diabetes awaited admission to the hospital. The off-site admitting internist ordered aspirin and a heparin drip, but neither medication was administered. On transfer to the acute care unit 2 hours later, the patient was diaphoretic, somnolent, tachycardic, and borderline hypotensive. The nurse called the internist and realized the heparin drip had never been started. When she went to administer it, the patient was unresponsive, hypotensive, and bradycardic. She called a code blue.
Jennifer Faig, MD, and Jessica A. Zerillo, MD, MPH; June 2018
Admitted to the oncology service for chemotherapy treatment, a woman with leukemia was noted to be neutropenic on hospital day 6. She had some abdominal discomfort and had not had a bowel movement for 2 days. The overnight physician ordered a suppository without realizing that the patient was neutropenic and immunosuppressed. Unaware that suppositories are contraindicated in neutropenic patients, the nurse administered the suppository. The patient developed a fever soon after receiving the suppository and required transfer to the intensive care unit for hypotension and management of septic shock.

Eric Poon, MD, MPH; May 2018
An elderly man with a history of giant cell arteritis (GCA) presented to the rheumatology clinic with recurrent headaches one month after stopping steroids. A blood test revealed that his C-reactive protein was elevated, suggesting increased inflammation and a flare of his GCA. However, his rheumatologist was out of town and did not receive the test result. Although the covering physician saw the result, she relayed just the patient's last name without the medical record number. Because the primary rheumatologist had another patient with the same last name, GCA, and a normal CRP, follow-up with the correct patient was delayed until his next set of blood tests.
Jamie M. Robertson, PhD, MPH, and Charles N. Pozner, MD; April 2018
A clinical team decided to use a radial artery approach for cardiac catheterization in a woman with morbid obesity. It took multiple attempts to access her radial artery. After catheter insertion, she experienced pain and pressure in her arm and chest. Review of the angiogram demonstrated the presence of an air embolism in the left coronary artery, introduced during the catheter insertion. Due to the difficulty of the procedure, the technician had failed to hold the syringe at the proper angle and introduced an air bubble into the patient's vessel.
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.
Mary G. Amato, PharmD, MPH, and Gordon D. Schiff, MD; January 2018
Admitted for intravenous diuretic therapy and control of his atrial fibrillation, an older man was mistakenly given metoprolol tartrate instead of his home dose of extended-release metoprolol succinate. That night, he developed atrioventricular block, experienced a pulseless electrical activity cardiac arrest, and died. Review of the case identified problems in the human factors design in the computerized order entry system that contributed to the prescribing error.
Ian Solsky, MD, and Alex B. Haynes, MD, MPH; December 2017
Prior to performing a bilateral femoral artery embolectomy on a man with coronary artery disease and diabetes, the team used a surgical safety checklist for a preoperative briefing. Although the surgeon told the anesthesiologist the patient would benefit from epidural analgesia continued into the perioperative period, he failed to mention the patient would be therapeutically anticoagulated for several days postoperatively. No postoperative debriefing was conducted. The anesthesiologist continued orders for epidural analgesia and the epidural catheter remained in place, putting the patient at risk of bleeding.
Varalakshmi Janamanchi, MD; Kunjam Modha, MD; and Christopher Whinney, MD; December 2017
At a preoperative evaluation for skin grafting surgery, a man's prescription medications were reviewed and updated in his medical record. During surgery, the patient experienced profuse bleeding, requiring transfusion with multiple units of blood. Postoperatively, the patient stabilized and the attending surgeon reexamined the patient's medications with him and asked about over-the-counter medications. The patient had been taking one aspirin per day, including the day of surgery. Although the patient was asked about blood-thinning medications at the preoperative visit, he was not asked about over-the-counter medications.
Cristiane Gomes-Lima, MD, and Kenneth D. Burman, MD; November 2017
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.
Nancy Staggers, PhD, RN; October 2017
Hospitalized with sepsis secondary to an infected IV line through which she was receiving treprostnil (a high-alert medication used to treat pulmonary hypertension), a woman was transferred to interventional radiology for placement of a new permanent catheter once the infection cleared. Sign-off between departments included a warning not to flush the line since it would lead to a dangerous overdose. However, while attempting to identify an infusion pump alarm, a radiology technician accidentally flushed the line, which led to a near code situation.

Lisa Strate, MD, MPH, and Sophia Swanson, MD; September 2017
An older man with Crohn disease was admitted for abdominal pain and high stool output from his ileostomy. Despite blood passing from his ostomy and a falling hemoglobin level, the patient was not given a timely blood transfusion.
Clinton J. Coil, MD, MPH, and Mallory D. Witt, MD; September 2017
A woman developed sudden nausea and abdominal distension after undergoing inferior mesenteric artery stenting. The overnight intern forgot to follow up on her abdominal radiograph, which resulted in a critical delay in diagnosing acute mesenteric artery dissection and bowel infarction.
Casey A. Cable, MD; David J. Murphy, MD, PhD; and Greg S. Martin, MD, MSc; September 2017
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.
- Spotlight Case
Amir A. Ghaferi, MD, MS; August 2017
Admitted to gynecology due to excess bleeding and low hemoglobin after elective surgery, an older woman developed severe pain, nausea, and new-onset atrial fibrillation. She was moved to the telemetry unit where cardiologists treated her, and she had episodes of bloody vomit. Intensivists consulted, but the patient arrested while being transferred to the ICU and died despite maximal efforts.

Shirley C. Paski, MD, MSc, and Jason A. Dominitz, MD, MHS; July 2017
Following an uncomplicated surgery, an older man developed acute colonic pseudo-obstruction refractory to conservative management. During a decompression colonoscopy, the patient's colon was perforated.
Sarah Doernberg, MD, MAS; July 2017
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.

Daren K. Heyland, MD, MSc; April 2017
When a 94-year-old woman presented for routine primary care, the intern caring for her discovered that the patient's code status was "full code" and that there was no documentation of discussions regarding her wishes for end-of-life care. The intern and his supervisor engaged the patient in an advance care planning discussion, during which she clarified that she would not want resuscitation or life-prolonging measures.
Matthew J. Doyle, MBBS; April 2017
Prior to undergoing a CT scan, a patient with no allergies documented in the electronic health record (EHR) described a history of hives after receiving contrast. During a follow-up clinic visit, the patient inquired whether this contrast reaction was listed in the EHR. Investigation revealed that it had been removed from the patient's profile, thus leaving the record with no evidence of allergy to contrast.

Daniel J. Morgan, MD, MS, and Andrew Foy, MD; March 2017
Brought to the emergency department from a nursing facility with confusion and generalized weakness, an older woman was found to have an elevated troponin level but no evidence of ischemia on her ECG. A consulting cardiologist recommended treating the patient with three anticoagulants. The next evening, she became acutely confused and a CT scan revealed a large intraparenchymal hemorrhage with a midline shift.
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.
Jeffrey J. Mucksavage, PharmD, and Eljim P. Tesoro, PharmD; January 2017
An emergency department physician ordered a loading dose of IV phenytoin for a woman with a history of seizures and cardiac arrest. However, he failed to order that the loading dose be switched back to an appropriate (and lower) maintenance dose, and 3 days later the patient developed somnolence, severe ataxia, and dysarthria. Her serum phenytoin level was 3 times the maximum therapeutic level.
Osama Loubani, MD; January 2017
A man with a history of cardiac disease was brought to the emergency department for septic shock of possible intra-abdominal origin. A vasopressor was ordered. However, rather than delivering it through a central line, the norepinephrine was infused through a peripheral line. The medication extravasated into the subcutaneous tissue of the patient's arm. Despite attempts to salvage the patient's wrist and fingers, three of his fingertips had to be amputated.
Gregory A. Filice, MD; December 2016
An older woman experienced acute kidney injury after being prescribed a nephrotoxic medication (amphotericin) intended for the ICU patient in the next bed. Caring for both patients, the covering resident entered the medication order for the wrong patient despite a policy requiring infectious disease consultation to prescribe IV amphotericin.
John D. McGreevey III, MD; November 2016
A transition from paper orders to CPOE left out an important safety reminder, resulting in mismanagement of an elderly patient's low potassium and magnesium levels. This led to a fatal arrhythmia. The paper-based electrolyte order set had provided a reminder that magnesium replacement should accompany potassium replacement; however, in the computerized system, a separate order set was necessary for each electrolyte.

Robert L. Wears, MD, PhD; October 2016
While attempting to order a CT scan with only oral contrast for a patient with poor kidney function, an intern ordering a CT for the first time selected "with contrast" from the list, not realizing that meant both oral and intravenous contrast. The patient developed contrast nephropathy.
Mitchell Levy, MD; October 2016
Administered antibiotics in the emergency department and rushed to the operating room for emergent cesarean delivery, a pregnant woman was found to have an infection of the amniotic sac. After delivery, she was transferred to the hospital floor without a continuation order for antibiotics. Within 24 hours, the inpatient team realized she had developed septic shock.
Jennifer Malana, MSN, RN, and Audrey Lyndon, PhD, RN; October 2016
A pregnant woman was admitted for induction of labor for postterm dates. Prior to artificial rupture of membranes (AROM), the intern found a negative culture for group B strep in the hospital record but failed to note a positive culture in faxed records from an outside clinic. Another physician caught the error, ordered antibiotics, and delayed AROM to allow time for the medication to infuse.

Brittany McGalliard, PharmD; Rita Shane, PharmD; and Sonja Rosen, MD; September 2016
An elderly woman with multiple medical conditions experienced new onset dizziness and lightheadedness. A home visit revealed numerous problems with her medications, with discontinued medications remaining in her pillbox and a new prescription that was missing. In addition, on some days she was taking up to five blood pressure pills, when she was supposed to be taking only two.
Annie Yang, PharmD, and Lewis Nelson, MD; September 2016
Admitted for knee surgery, a man was given his medications at 10 PM, including oral dofetilide (an antiarrhythmic agent with a strict 12-hour dosing interval). In the electronic health record, "q12 hour" drugs are scheduled for 6 AM and 6 PM by default. Because the patient was scheduled to leave for the operating room before 6 AM, the nurse gave the dose at 4 AM. Preoperative ECG revealed he had severe QTc prolongation (putting him at risk for a fatal arrhythmia), and surgery was canceled.
Jennifer Merrilees, RN, PhD, and Kirby Lee, PharmD, MA, MAS; May 2016
An elderly man with early dementia fractured his leg and was admitted to a skilled nursing facility for physical therapy. On his third day there, he became delirious and agitated and was taken to the emergency department and hospitalized. A few days later, doctors involuntarily committed him and administered risperidone, which worsened his delirium.
Cindy S. Lee, MD, and Christopher P. Hess, MD, PhD; May 2016
An older man with a history of heavy smoking and chest pain underwent a chest CT in the emergency department that showed no evidence of an aortic dissection on the preliminary read. Although the patient followed up soon thereafter with a new primary care physician, it was not discovered until several months later that a suspicious lung nodule had been spotted on the initial CT.
- Spotlight Case
Patricia Juang, MD, and Kristen Kulasa, MD; April 2016
While hospitalized, a man with diabetes had difficult-to-control blood sugars, with multiple episodes of both critical hypoglycemia and serious hyperglycemia. Because "holds" of the patient's insulin were not clearly documented in the electronic health record and blood sugar readings were not uploaded in real time, providers were unaware of how much insulin had actually been given.
Jeanne M. Farnan, MD, MHPE; April 2016
A man with a pulmonary embolus was ordered argatroban for anticoagulation. The next day, an intern noticed that the patient in the next room, a woman with a GI bleed, had argatroban hanging on her IV pole, but the label showed the name of the man with the pulmonary embolus. The nurse was notified, the medication was stopped, and the error was disclosed to the patient.
Vineet Chopra, MD, MSc; February 2016
Hospitalized with poorly controlled diabetes, a man had a peripherally inserted central catheter (PICC) placed for intravenous pain medications, intravenous fluids, and parenteral nutrition. The next day, the patient complained of headache, unilateral vision loss, and left-sided tingling and numbness. Misplacement of the PICC in a left-sided superior vena cava had led to embolic strokes.
Kevin Moore, MBBS, PhD; December 2015
A man with cirrhosis and abdominal distension was found to have significant ascites. The emergency department providers performed a large volume paracentesis to relieve his symptoms, but, as the 10th liter of fluid was removed, the patient became acutely hypotensive.
Tosha Wetterneck, MD, MS; December 2015
Hospitalized with nonketotic hyperglycemia, a man was placed on IV insulin and his blood sugars improved. That evening, the patient was transferred to the ICU with chest pain and his IV insulin order was changed to sliding scale subcutaneous insulin. However, over the next several hours, the patient again developed hyperglycemia.
The Risks of Absent Interoperability: Medication-Induced Hemolysis in a Patient With a Known Allergy
- Spotlight Case
Jacob Reider, MD; October 2015
After leaving Hospital X against medical advice, a man with paraplegia presented to the emergency department of Hospital Y with pain and fever. The patient was diagnosed with sepsis and admitted to Hospital Y for management. In the night, the nurse found the patient unresponsive and called a code blue. The patient was resuscitated and transferred to the ICU, where physicians determined that the arrest was due to acute rupturing of his red blood cells (hemolysis), presumably caused by a reaction to the antibiotic. Later that day, the patient's records arrived from three hospitals where he had been treated recently. One record noted that he had previously experienced a life-threatening allergic reaction to the antibiotic, which was new information for the providers at Hospital Y.
Jonathan Carter, MD; October 2015
A patient with severe abdominal pain was admitted to the medicine service for observation, pain control, and serial abdominal examinations. Surgical consultation was not requested at admission. Two days later, the patient's abdomen worsened. Consultation led to urgent surgery, which revealed a strangulating bowel obstruction and associated perforation.
