The Hippocratic Oath asks of physicians, in their care of patients, to “do no harm or injustice to them”. However, the Oath may be broken when forensic opinions are rendered regarding which gunshot wound is an entrance and which is an exit based upon the size of the wound and not its physical characteristics. The medical and scientific literature has repeatedly documented that the non-forensic healthcare provider has a miserable ability to correctly interpret gunshot wounds. The “Interpretation of Fatal, Multiple and Exiting Gunshot Wounds by Trauma Specialists”, published in the Journal of Forensic Sciences, Vol. 39, No. 1, found that clinical physicians have a great deal of difficulty in correctly distinguishing between entrance and exit wounds. What are the reasons for these misinterpretations? Their opinions were based upon the size of the wound, not its physical characteristics. Physical characteristics will tell you if the wound is an entrance or exit, the range of fire and if the injuries are consistent with the history given by the victim. To avoid the misinterpretation and therefore the misdiagnosis of gunshot wounds, police, nurses, physicians and prosecutors need additional forensic training. This training is designed for nurses, physicians, police officer and prosecutors. The knowledge gained will assist attendees in evaluation, diagnosis, investigation or prosecution of gunshot wounds, including domestic and officer-involved shootings.
