Assessing the influence of non-treatment variables in a study of outcome from severe head injuries.
An evaluation was made of the impact of non-treatment variables on severely injured head trauma patients. The principal findings were: 1) severity of injury was the best predictor of outcome; 2) patient's age had a statistically significant but marginally useful impact on outcome; 3) a regression analysis showed that duration of transport, up to 4 hours, had no impact on outcome; 4) time from accident to intubation had a marginal impact on outcome; and 5) one-way analysis of variance showed that mode of transportation, whether helicopter, ambulance, or other means had no impact on outcome.
