Abstract:
Objective To develop converting rule from international classification of disease (ICD) codes of trauma to abbreviated injury scale (AIS) values so as to provide clues for a simple and convenient trauma scoring way. Methods The corresponding set relations were made for ICD-9CM codes and AIS-90 codes with similar code meanings in the trauma diseases. Based on medical theories and knowledge, 8 indeces closely associated with injury severity were worked out for each ICD-9CM code of trauma diseases by using the database of discharge abstracts of trauma patients. Discriminant analysis was used to set up corresponding relations of ICD-9CM codes with AIS values. Results Seven indices were selected for discriminant function. Corresponding relations of all ICD-9CM codes of trauma diseases with AIS values was made through nonparametric discriminant method. Under deliberation and revision by several clinical experts on traumatology, the converting rule was established eventually. Consistency analysis between the sample's international classification of disease injury severity score (ICISS) values and injury severity score (ISS) values showed that ICISS values were closely correlated with 2-ICISS (Y=Ln), with correlation coefficient of 0.831 1 ( P
