Abstract

We have analyzed a sample of 1008 persons injured in road accidents in the Province of Quebec in the year 1974 in order to explore the accuracy of road accident statistics and to obtain a classification of victims by severity of injuries. We have compared police and hospital reports for the victims, all these data being gathered in the records of the Third Party Liability Service of the Quebec Health Insurance Board. All fatal cases were notified by police but only 7 of the 22 deaths were correctly notified. For the in-patients, 72.6% were correctly notified and 3.4% were not reported by the police. Only 53.5% of the out-patients were properly notified and 24.4% were not reported by the police.

Using these results, we produced corrected figures for provincial transport statistics which appeared to underestimate the number of victims by 22%. From the data obtained from the Department of Social Affairs, we have estimated that the number of road victims lies between 70,093 and 79,600.

We then computed the Injury Severity Score (I.S.S.) of each victim and found that in-patients were more than three times more injured than out-patients. Pedestrians appeared to be the type of road user with the greatest ISS; occupants of cars ranked second followed by the motorcyclists and the cyclists. Fractures were the most common injury and the extremities were the region most frequently injured.

A strong positive relation was found between the ISS and the period of treatment and the length of stay in hospital confirming the relevance of the ISS for summarizing injury severity, especially in patients with multiple trauma. Finally costs of medical services were estimated for our average in-patient and out-patient.
