Avoidable factors contributing to the death of head injury patients in general hospitals in Mersey Region.

In 1975 and 1976 190 head injury patients died after admission to 19 general hospitals in Mersey Region or after transfer to the regional department of neurosciences. Their hospital case-notes were examined. Avoidable factors definitely contributing to death were identified in 58 (30%), and those possibly contributing to death in another 45 (24%). Of the avoidable factors 38% occurred in patients who "talked and died" and 77% in patients with intracranial haematomas. The most common avoidable factors were failure to recognise the development of a haematoma, respiratory difficulty leading to hypoxia, hypotension, and convulsions. The following recommendations are made: hospital case-notes of all head injury deaths should be assessed by a panel of senior consultants; all patients unconscious for 4 h in primary surgical wards in general hospitals should be transferred to the regional department of neurosciences; and fewer patients with minor head injuries should be admitted for observation.
