A 52-year-old woman presented for a lumpectomy with lymphoscintigraphy and sentinel lymph node biopsy (SLNB) after being diagnosed with ductal carcinoma in situ (DICS). On the day of surgery, the patient was met in the pre-operative unit by several different providers (pre-operative nurse, resident physician, attending physician, and anethesiology team) to help prepare her for the procedure. In the OR, the surgical team performed two separate time-outs while the patient was being prepped, placed under general anesthesia, and draped. After the attending physician began operating, she realized that no radiotracer dye had been injected for the SNLB – a key process step that was supposed to have occurred prior to the surgery. The nuclear medicine team never saw the patient preoperatively, and none of the staff members or teams realized this until the patient was under general anesthesia with an open incision. The commentary discusses how pre-operative checklist protocols can help multidisciplinary teams avoid communication errors and reduce opportunities for adverse events.

After a failed induction at 36 weeks, a 26-year-old woman underwent cesarean delivery which was complicated by significant postpartum hemorrhage. The next day, the patient complained of severe perineal and abdominal pain, which the obstetric team attributed to prolonged pushing during labor. The team was primarily concerned about hypotension, which was thought to be due to hypovolemia from peri-operative blood loss. After several hours, the patient was transferred to the medical intensive care unit (ICU) with persistent hypotension and severe abdominal and perineal pain. She underwent surgery for suspected necrotizing fasciitis, but necrosis was not found. The patient returned to the surgical ICU but deteriorated; she returned to the operating room, where she was found to have necrotizing soft tissue infection, including in the flanks, labia, and uterus. She underwent extensive surgery followed by a lengthy hospital stay. The accompanying commentary discusses the contribution of knowledge deficits and cognitive biases to diagnostic errors and the importance of structured communications between professionals.

An elderly man with a complicated medical history slipped on a rug at home, fell, and injured his hip. Emergency department evaluation and imaging revealed no head injury and a left intertrochanteric hip fracture. Although he was admitted to the orthopedic surgery service with surgery to fix the fracture initially scheduled for the next day, the operation was delayed by 3 days due to several emergent trauma cases and lack of surgeon availability. He ultimately underwent surgery and was discharged a few days later but was readmitted several weeks later with chest pain and shortness of breath. He was found to have a pulmonary embolism; anticoagulation was initiated. The patient's rehabilitation was delayed, his recovery was prolonged, and he never returned to his baseline functional status.

While undergoing an elective coronary artery bypass graft (CABG) and ablation, an elderly man had a pulmonary artery catheter (PAC) placed to monitor his hemodynamic status. During the operation, the team was informed that another patient needed an emergency CABG. In the rush to attend to the second patient, the PAC in the first was left inflated for a prolonged period, which could have led to a catastrophic complication.
