title: Helicopter Emergency Medical Service operating from the Royal London Hospital: the first year.
abstract: The additional workload on the support hospital created by using a helicopter for emergency trauma has been assessed in the first year of operation. A total of 135 patients were brought to the Royal London Hospital, of whom 30 died, 34 were transferred for convalescence or rehabilitation to another hospital, and 71 discharged home. The median Injury Severity Score was 17 (range 0-75) and 82 patients (60.7 per cent) had a reduced Revised Trauma Score at the scene. Blunt injury greatly outnumbered penetrating trauma (117 versus 15 patients). Accidental injuries accounted for 77.0 per cent of the total, self-inflicted wounds 14.1 per cent and assaults 8.9 per cent. Parameters employed to assess workload were hospital bed-days used (total 2361), operations (118, occupying 287 h of theatre time) and blood transfusion (total 702 units used). The second 6-month study period showed a considerable increase in the number of patients admitted (102 versus 33) because of increased efficiency in call-out procedures.
