Abstract
We studied the occurrence of head injury in two different Italian regions: Romagna and Trentino. Both geographical areas attract large numbers of seasonal tourists. The study was carried out over 1 year (January 1, 1998 to December 31, 1998), prospectively in Romagna and retrospectively in Trentino because of their different head injury management protocols. The study was based on all admissions to hospital extracted by medical staff from the case records, and all cases were identified by the ICD-9 codes (ranges: 800.0–800.3, 801.0–801.3, 803.0–803.3, 850, 851.0–851.1, 852.0–852.1, 853.0–853.1, 854.0–854.1). The annual incidence of hospitalization for head injury was 314/100,000, 297 for Romagna and 332 for Trentino. The causes of head trauma and the type of injuries were similar to those reported in the international literature, and so were the characteristics of the population at risk. Romagna recorded a higher incidence of head injury among the elderly, probably due to the widespread use of bicycles without safety helmets. In Romagna, where neurosurgery departments exist, hospital mortality was low (8/100,000/year). Based on similar international literature findings, different prevention measures are suggested to reduce the occurrence and severity of head injury.
