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.

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.

Orthopedic surgeons rounding on an elderly Cantonese-speaking woman recommend conservative, nonsurgical treatment for her broken hip, as their examination noted that the patient was able to walk.

Further investigation revealed that the surgeons had actually walked the patient's roommate, another Cantonese-speaking woman.
