Comparison of injury severity assigned to lower extremity skeletal damages versus upper body lesions

Abstract: An earlier investigation of frontal collisions revealed the facts that offset collision is the most common type and that among injured belted car occupants serious injuries (AIS 3+) to the lower extremities are more frequent than injuries in the upper torso and head region. When attempting to estimate the overall significance of these injuries including injury induced societal costs, we realized that equally coded injuries (AIS 3) obviously have to be assigned widely differing numbers in terms of treatment period, temporary disability, and permanent impairment. To provide the automobile engineer a better tool for cost/benefit analyses, the AIS should be revised with respect to these criteria or an additional cost related scaling system should be developed.

Traumatology and the injury severity score

Abstract: Traumatology is the study of patients with injuries due to accidents. It is not a recognised specialist subject. With the aid of the injury severity score an analysis can be made of the cause of death of multi-trauma-patients. Haemorrhage, within 24 hours, is the main cause of death but patients dying within an hour are not considered in this respect. From the analysis based on the iss it is clear that the scheme of treating serious traumatic patients should be changed. A good team of specialists is needed in a good hospital. In the writer's hospital a patient with an iss of 75 was kept alive. (TRRL)

A detailed injury severity scale for lower limbs based on analysis of injuries sustained by pedestrians

Abstract: This paper is based on the results of 50 pedestrian cadaver tests in which the lower limbs injuries were carefully analyzed. The leg injury distribution, the consequences of these injuries will be evaluated through the analysis of equivalent injuries sustained by pedestrian in traffic accidents. These injuries are of several types and involve all biological tissues of lower limbs. The authors propose a classification of these injuries according to their kind, their location, their number and their association. This classification shows that present scales are not sufficiently detailed and are not suitable for the reality of these injuries. On this basis they propose intermediate stages in order to refine the present AIS and MAIS scales. For the covering abstract of the conference see HS-036 716. (TRRL)

Compatibility of the icd-9-cm and ais 80. an update

Abstract: The feasibility is being explored of coding the Abbreviated Injury Scale (AIS) severity directly from hospital discharge diagnoses which have been classified using the World Health Organization's International Classification of Diseases (ICD). The ability to convert ICD rubrics to AIS severity codes would greatly enhance the scales utility. A clinical modification of the 9th revision of the ICD (ICD-9-CM) giving increased specificity has been recently developed. Several simplifying assumptions were made to facilitate conversion of the ICD-9-CM. Some of the more important ones are listed. A computerized ICD-9-CM-AIS '80 conversion table has been developed which can be used to assign severity scores to those rubrics for which a compatible AIS description exists. The validity of this conversion table is currently being tested. Although primary results are encouraging with regard to the utility of the table, certain limitations have been noted.

New ways to use the abbreviated injury scale: a guide to evaluating threat to life

Abstract: The Abbreviated Injury Scale has suggested a new method of relating injury severity to loss of life. The new method is based on the Probability of Death Score which provides a routine means of assigning a specific probability of death to each trauma victim. The individual probabilities of death can be summed over a group to calculate the total expected deaths in the group. Likewise, the individual probabilities of death can be combined with standard demographic data to calculate expected person years lost. The expected deaths and person years lost in turn can be used to advantage in planning and evaluating programs of injury control and prevention.

Testing the validity of the Abbreviated Injury Scale: Report of an ongoing project

Abstract: This paper describes an ongoing research project which is designed to contribute to the validity of the Abbreviated Injury Scale The methodological approach involves using the subjective estimates of physicians to develop several scales which represent specific conceptualizations of injury severity, namely, mortality rate, hospital length of stay, length of recovery period, and permanent disability/activity limitation The relationship between these measurement scales and the Abbreviated Injury Scale (AIS) will be analyzed via multivariate data analysis techniques in an effort to clarify what aspects of injury severity are being measured by the AIS
