Head injury patients admitted to general hospitals in Merseyside

During 1975 and 1976, 11837 patients with head injury were admitted to 16 general hospitals serving 2.1 million people. Eight hundred and seventy-five had fractures of the skull, 178 died and 103 were transferred to the regional department of neurosciences. A fall was the cause of injury in 49 per cent, a traffic accident in 24 per cent and assault in 17 per cent. Seventeen per cent of adult patients had taken alcohol and 16 per cent had major extracranial injuries (including fractures of the bones of the face). Sixty-seven per cent stayed in hospital for 0-48 hours and 8 per cent for 8 days or more. The mortality rate and the number of deaths associated with avoidable factors both increased with the patient's ages. After standardization for age and sex, neither of these measures of the effectiveness of the management of head injury in hospital was found to differ significantly amongst the sixteen hospitals; nor were they related to differences in the way in which head injury patients were managed (for example, duration of stay in hospital) or to admission policy, work load (number of patients admitted with head injury per year) or the distance by road to the regional neurosciences department.
