The epidemiological aspects of the mortality, morbidity and the costs of neurotrauma in New South Wales 1977 were outlined in Part I of this report.* Part II outlines the profile of surgical work in this field in New South Wal GS in 1977. In all, 21,973 patients were admltted to New South Wales Hospitals in 1977 for neurotraumatic conditions (85% with head, 13% wlth spinal and 2% with peripheral nerve injuries); and 1,513 patients required surgery (49% with head, 22% wlth spinal and 29% with peripheral nerve injuries). The profile of surgery for disc disease Is outlined.The participation of neurosurgeons in the management of neurotrauma Is assessed.

An epidemiological study of neurotrauma in New South Wales, South Australia and the Australian Capital Territory, 1977, was initiated and sponsored by the Neurosurgical Society of Australasia, conducted by its Trauma Subcommittee In collaboration with the Division of Health Services Research, Health Commission of New South Wales, funded by the Australian Brain Foundation and the Commonwealth Department of Health and supported by the Health Commissions of New South Wales and South Australia. The following communication Is structured so as to present the esssential findings on mortality, morbidity and costs in New South Wales in 1977 in the first part and the more specific statistical profile of surgical treatment in New South Wales, 1977, in a separate, second part. The most revealing data found by this research is that cranio‐cerebral and spinal injury was the leading cause of death up to the age of 44 in New South Wales (and South Australia) and up to the age of 49 in the male population and in the country regions. It accounted for 45% of all deaths to those aged 15 to 24. Cranio‐cerebral and spinal injury caused 71% of all deaths on the roads. Sixty‐four per cent of those dying in road accidents never reached hospital. The figures for mortality and morbidity in the country regions were significantly worse than those in the metropolitan regions. The most important causes were identified and recommendations aimed at reducing this record were formulated.

This study of 1161 neurotrauma patients in New South Wales hospitals was designed to examine the role of preventable causes of death and disability in cases of spinal injury, extradural, subdural and multiple intracranial haematomas in order to make recommendations for improvements in accident, emergency, ambulance and hospital services. Methods have been developed for standardizing diagnosis in different classes of hospital for the assessment of severity in terms of the patient's age, sex, physical signs, head and spine injuries and other injuries. Estimates have been made of the number of preventable deaths by a case control study of each category of neurotrauma under study.

Preventable causes of death and disability have been studied retrospectively in a series of 1161 cases of neurotrauma occurring in New South Wales in 1977–78, and prospectively in 153 cases of neurotrauma occurring in country districts in South Australia in 1981–82. In the first study, it was found that at least 80 deaths could be attributed to preventable causes; chiefly, transfer to an inappropriate hospital and/or delay in instituting treatment. Apparent failures in initial management of shock and airway obstruction were evident in this study and also in the South Australian study, which identified major deficiencies in cardiorespiratory management in 7% of cases transferred from country areas. These studies confirm that there is a need for better training, at all levels, in the management of neurotrauma. They also provide powerful arguments for the concept of an integrated regional trauma service.

Two hundred and two patients with acute and severe spinal injuries were treated in various hospitals in New South Wales during 1977 and 1978. Of these, 132 (65%) were cervical, 60 (30%) thoracic, eight (4%) lumbar and two were inadequately recorded. A major concurrent injury to the head was present in every third patient, to the chest in every fourth patient, and to the limbs in every fifth patient. The outcomes of patients reported in this series make it one of the worst in the literature. Sixty‐nine (34%) patients died in hospital; of the 133 survivors, only 22 (11%) have resumed work, the remainder being partially or totally disabled. It is estimated that another 302 patients died before arrival in hospital. In country areas, the time lags between accident and ambulance notification, and between notification and arrival at hospital, were uncertain in many cases, but periods in excess of 2 hours were recorded in 28 (14%). One‐man ambulances or private vehicles were used in at least 43 cases (21%). After admission, 139 patients were transferred to other hospitals for definitive treatment, arriving after an average time of 22 h (median time 9 h); for such patients, the original hospital presumably served as a first aid station. A case control study suggests that preventable delay in transport, inappropriate treatment, and failure to correct shock may have been causative factors in 16 deaths in this series. Reduction of the time lag between accident and institution of definitive treatment will save lives, and may avoid some crippling neurological deficits. To achieve this, there is an urgent and overdue need to integrate ambulance and hospital services and to establish efficient multidisciplinary trauma centres.
