Outcome of patients with neurotrauma: the effect of a regionalized trauma system.
A system of regionalized trauma care was introduced to Sydney in early 1992. This study was carried out to assess the effect of regionalization on the outcome of patients suffering major head injury within the central Sydney area. A prospective before and after study extending over 3 years and centred on the time of designation of Royal Prince Alfred Hospital (RPAH) as a trauma centre, was the methodology used. The study group consisted of all patients admitted with head injury (Glasgow Coma Score < 9; admission systolic blood pressure > 90 mmHg; Injury Severity Score > 15) to RPAH from the central Sydney area. Outcome criteria include survival rates, transfer numbers, and time to definitive neurosurgical care. Fifty patients were entered during the first 18 months of the study, and 38 during the second 18 months. Fifteen in the first group required evacuation of intracranial mass lesions, as did nine in the second group. The overall mortality fell from 42 to 26% (P = 0.13). During the study period there were 77 primary retrievals and 20 required evacuation of mass lesions. The median time from injury to commencement of operation in these patients was 2 h 13 min (range 1 h 3 min-5 h 35 min). There were 11 transfers, four requiring craniotomy. The median time from injury to surgery was 7 h 24 min (range 3 h 2 min-10 h 25 min; P < 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)
