Forensic considerations of missed diagnoses in trauma deaths.

Injuries missed at initial diagnoses or operations have the potential to cause disastrous complications in trauma patients. Understanding the etiology of unrecognized injuries is essential in minimizing its occurrence. For this purpose, we scrutinized the treatment and the autopsy records of the trauma deaths from 2000 to 2004 to determine the frequency, body regions, severity and causes of injuries that escaped recognition during the initial assessment, primary, secondary and tertiary surveys by the clinical team in patients who died of trauma. We also examined the accuracy of the cause of death as recorded on death certificates. The frequency of unrecognized injuries was found to be 11% in all trauma deaths. Abdomen (40%) and head (29%) were the more common regions of the body where injuries were frequently missed. System related errors (68%) and patient related factors (32%) were responsible for the injury remaining unrecognized. It was concluded that the injuries may be missed at any stage of the management of patients with major trauma and repeated assessments both clinical and radiological are mandatory not only to diminish the problem but to avoid litigation as well.
