Multiple injuries: an overview of the outcome.

To measure the functional outcome we analyzed 723 consecutive patients with multiple injuries (Abbreviated Injury Scale (AIS)/Injury Severity Score (ISS) > or = 16, mean ISS 30.1) treated at the University Hospital Groningen, the Netherlands, between 1985 and 1989. Age, sex, type of accident, AIS/ISS, discharge destination, length of hospital stay and functional outcome (measured by the Glasgow Outcome Scale) are described. The patients were young (mean age 33.4 years) and 186 died (25.7%) mainly because of severe head injuries. Half of the survivors could be discharged home and 29% were transferred to a rehabilitation center. Rehabilitation centers predominantly treat patients with severe injuries of the head or neck and extremities. These injuries, together with spinal cord injuries, appeared to be responsible for the majority of permanent disabilities. Although the functional outcome deteriorated linearly with increasing AIS/ISS, the final functional result was good: in the first half year after injury there was considerable recovery; after that there was further slight recuperation. Two years after injury, 68% had mild or no disabilities, 19% were moderately disabled, and 7% severely disabled.
