Following a motor vehicle accident, a 63-year-old man is scheduled for surgery. The emergency physician notes a posture abnormality in the distal left lower limb and a fracture-dislocation of the right hip and acetabulum based on the radiology report. The senior orthopedic resident mistakenly notes a fracture dislocation of the left hip. The surgeon's examination of the patient in the operating room shows an externally rotated and shortened left lower limb. The surgeon reduces the left hip and inserts a pin in the left tibia. A review of postoperative imaging leads to a second surgery on the fracture-dislocation of the right hip. Which of the following strategies is most likely to prevent the recurrence of this type of error?
AMarking the surgical site
BImplementing a checklist
CConducting a preoperative time-out
DVerifying the patient’s identity
EPerforming screening X-rays
