A 75-year-old man is recovering in the hospital from a left-sided below-the-knee amputation. Three days after the surgery, the patient suddenly develops chest pain and shortness of breath that last for 20 minutes. His pain medication is increased, which improves the pain but not the shortness of breath. X-ray of the chest is negative for a pulmonary embolus, so the medical team decides to monitor him expectantly. The next day, a similar episode of shortness of breath and chest pain occurs. The patient then sustains cardiac arrest and dies. Autopsy reveals multiple pulmonary emboli. The family threatens to sue for malpractice for mismanaged postoperative care. Which of the following is necessary to prove malpractice?
