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.

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.
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.
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.
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.

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.
Steven R. Kayser, PharmD; September 2015
Following a myocardial infarction, an elderly man underwent percutaneous coronary intervention and had two drug-eluting stents placed. He was given triple anticoagulation therapy for 6 months, with a plan to continue dual anticoagulation therapy for another 6 months. Although the primary care provider saw the patient periodically over the next few years, the medications were not reconciled and the patient remained on the dual therapy for 3 years.

Edward Etchells, MD, MSc; June 2015
After multiple visits to both his primary care provider and urgent care for chronic burning left foot pain attributed to peripheral neuropathy, a man presented to the emergency department with worsening symptoms. His left lower leg was dusky and extremely tender, with non-palpable pulses. CT angiography revealed complete blockage of the left superficial femoral artery due to atherosclerotic peripheral arterial disease. The patient required emergent vascular bypass surgery on his left leg, and ultimately, an above-the-knee amputation.
Frank I. Scott, MD, MSCE, and Gary R. Lichtenstein, MD; June 2015
Admitted to the hospital with a small bowel obstruction and ileitis consistent with an exacerbation of Crohn disease, a man was given empiric antibiotic therapy and infliximab prior to consultation with gastroenterology. Gastroenterology recommended sending stool studies and initiating infliximab only after those studies were negative for infection. The stool studies were sent, but the primary team did not discontinue the infliximab. The patient was found to have Clostridium difficile infection.

David Shimabukuro, MD; May 2015
An older woman with a history of pulmonary hypertension, chronic obstructive pulmonary disease, and coronary artery disease was admitted to the hospital with pneumonia. She received levofloxacin (administered approximately 3 hours after presentation). Twenty-four hours after admission, her blood cultures grew methicillin-resistant Staphylococcus aureus, and vancomycin was added to her antibiotic regimen. The patient developed respiratory failure requiring mechanical ventilation as well as septic shock requiring vasopressors.
Megumi J. Okumura, MD, MAS, and Roberta G. Williams, MD; May 2015
A 21-year-old woman with a history of Marfan syndrome complicated by aortic root dilation presented to the emergency department with abdominal pain and was found to be pregnant. It was her second pregnancy; she had a therapeutic abortion 4 years earlier due to the risk of aortic rupture during pregnancy. At that time, the patient had been advised to have her aortic root surgically repaired in the near future. However, after the patient turned 18, she did not receive regular follow-up care or pre-conception or contraception counseling despite the risk to her health should she become pregnant.
Dustin W. Ballard, MD, MBE; David R. Vinson, MD; and Dustin G. Mark, MD; May 2015
A man with a history of poorly controlled diabetes and pancreatic insufficiency was found unresponsive. Paramedics transported him to the emergency department, where a resident placed a right internal jugular line for access but was unable to confirm placement. The resident pulled the line, opened a second line insertion kit, started over, and confirmed placement with ultrasound. The patient went into cardiac arrest, and a chest radiograph noted a retained guidewire in the pulmonary artery.
Timothy W. Farrell, MD; April 2015
For a man with hypertension, prostate cancer, and chronic kidney disease hospitalized with acute kidney injury, discharge planning created numerous challenges. The inpatient team wanted a 1-week follow up, but the patient was new to this health system and had not yet seen a primary care provider. With the next available appointment in 6 weeks, the patient was instructed to call the urgent care clinic (which offered only same-day appointments) 1 week later. However, he never made it to the clinic and presented to the emergency department 2 weeks later with poorly controlled hypertension.

A man with suspected renal cell carcinoma seen on CT in the right kidney was transferred to another hospital for surgical management. The imaging was not sent with him, but hospital records, which incorrectly documented the tumor as being on the left side—were. The second hospital did not obtain repeat imaging, and the surgeon did not see the original CT prior to removing the wrong kidney.
Krishna Moorthy, MD, MS; January 2015
Following outpatient laparoscopic surgery to repair an inguinal hernia, a man with no significant past medical history had high levels of pain at the surgical site and was admitted to the hospital. With sustained pain on postoperative day 3, the patient developed tachycardia with abdominal distension and a low-grade fever. A CT scan revealed a bowel perforation, which required surgery and a lengthy ICU stay due to septicemia.
Jeffrey H. Barsuk, MD, MS, and Cynthia Barnard, MBA, MSJS; December 2014
In a simulation exercise conducted in an institution that felt it was prepared for patients with actual or suspected Ebola, a man presented to the emergency department with symptoms of nausea, vomiting, and fever. He had recently returned to the US from Sierra Leone. The nurse initiated an isolation protocol and the critical care team all donned personal protective equipment. During transport, confusion about which elevators to use potentially exposed 30 staff members to Ebola. Additional issues occurred including breaching sterile technique while inserting a central line and confusion about the process to transport the patient's blood to the lab.

A man with atrial fibrillation underwent ablation in the catheterization laboratory under general endotracheal anesthesia. The patient was extremely stable during the 7-hour procedure with vital signs hardly changing over time. Inadvertently, the noninvasive blood pressure measurement stopped recording for 1 hour but went unnoticed. After the error was discovered, the case continued without any problems and the patient was discharged home the next day as planned.
Don C. Rockey, MD; July-August 2014
Presenting with jaundice and epigastric pain, a woman with a history of multiple malignancies was admitted directly for an ultrasound-guided liver biopsy. After the procedure, the patient had low blood pressure and complained of new abdominal pain, which worsened over the next 2 hours. The bedside nurse soon found the patient unresponsive.
