title: Head injury, subarachnoid hemorrhage and intracranial pressure monitoring in Italy.
abstract: BACKGROUND
  Intracranial pressure monitoring is recommended for the management of severe head injury and is increasingly used during intensive care for other pathologies, such as subarachnoid hemorrhage. However, it is still not uniformly applied in different centers. The objectives of this paper are to summarize the frequency and the modalities of intracranial pressure (ICP) monitoring in different centers in Italy; to describe its use in traumatic brain injury (TBI) and in subarachnoid hemorrhage (SAH); and to identify areas for improvement.
  
  
  METHODS
  The medical directors of either the neurosurgical department or the intensive care unit, or both, of every Italian neurosurgical center were personally interviewed. They answered specific questions about TBI and SAH patients admitted, and ICP monitoring used, in their units. Data were cleared of any obvious inconsistencies and entered in a database for analysis. All analyses were based simply on the data declared.
  
  
  RESULTS
  The clinical information was obtained from 9137 TBI cases, of whom 4240 severe, and 3151 SAH patients. Among the 106 participating centers, 15 did not use ICP monitoring at all. The remaining 91 had used 3293 ICP devices during the year 2001; 146 were used in tumor cases, 2009 in TBI, and 1138 in SAH. Twenty-two percent of TBI cases admitted to centers with ICP equipment were monitored. Restricting this analysis to severe cases, 47% of TBI with a GCS <8 had ICP. On average, 36% of SAH underwent ICP monitoring. The proportions of head injury and SAH cases who underwent ICP monitoring varied widely in the different centers. Dividing the country into three main areas (north, center and south), there were considerable differences both in the rate of admissions per million inhabitants and in the frequency of ICP monitoring.
  
  
  CONCLUSIONS
  ICP monitoring in Italy is used in most, but not all, centers. ICP is measured fairly extensively in head injury cases, but a significant proportion of SAH patients is monitored as well. There are substantial differences in the frequency of ICP monitoring in different parts of the country. The use of ICP for both these indications, and the rates of admission to specialized centers, could be improved.
