[Minor head injury management in Spain: a multicenter national survey]

Despite of the high incidence of minor head injury, there is still controversy and disparity of criteria regarding its management. The lack of consensual protocols and clinical guidelines can lead to deficiencies in the attention to these patients and to inadequate use of resources. The objective of this study has been to describe the present situation of the management of this entity in the neurosurgical departments of the Spanish public hospitals, and to compare it with other European countries.

A 57-item questionnaire regarding different aspects of minor head injury was designed and distributed to the 66 neurosurgical departments of the Spanish National Health System between December 1999 and February 2000.

A 83.3% of responses were obtained. More than 92,000 patients per year are assisted at the Spanish third-level hospitals (general hospitals) after suffering a minor head injury. In-hospital on duty neurosurgeons are not available in 49.1% of the Spanish neurosurgical departments. Only in 7.3% of the centres the neurosurgeon is the first physician that assists these patients. However, in 52.7% of the hospitals neurosurgical evaluation is required if the patient refers transient loss of consciousness. A GCS score of 13 is still included in the group of minor head injuries in 29.1% of the centres. Although 89.1% of the surveyed neurosurgical departments considered as satisfactory the attention they provide to these patients, 85.5% think that it would be convenient to elaborate clinical guidelines. Cranial x-ray is considered a useful diagnostic tool by only 38.2% of the centres, however, 89.1% of them still use it as a routine. CT-scan is systematically indicated in all patients after suffering a mild head trauma only in 5.5% of the centres, although it is completely available in 74.5% of them. The study of economical costs shows that choosing cranial CT as screening tool in these patients would mean a 40.6% reduction in costs compared to a management based on x-ray plus in-hospital observation.

This study shows the inter-hospital variability of minor head injury management in Spain. Clinical guidelines are considered as positive and necessary. Although the Spanish situation is similar to that in other European countries, following the tendency toward a broader cranial CT utilisation, would improve diagnosis profitability and economical efficiency. The results of this study may contribute to the creation of consensual protocols and clinical guidelines in our country that help in daily practice decision-making optimising assistance quality.
