The Abbreviated Injury Scale and its correlation with preventable traumatic accidental deaths: a study from South Delhi.

Anatomic trauma scoring systems are fundamental to trauma research. The Abbreviated Injury Scale (AIS) and its derivative, the Injury Severity Score (ISS), are the most frequently used scales. In a prospective study, 400 autopsies of road traffic accident victims performed between January 2002 and December 2003 were coded according to the AIS and ISS methods. All the cases were classified into different injury groups according to the Injury Severity Scale. Fifty-eight cases (14.5%) were assigned an ISS value of <25; 244 (61%) cases were valued between 25-49; 38 cases (9.5%) were valued between 50-74 and 60 (15%) cases had a value of 75. On analysis of medical care, in cases with ISS<50, about 96% of the victims did not receive optimal care quickly enough with a lack of pre-hospital resuscitation measures and lengthy transportation time to hospital being of major importance.
