The aim of this prospective, population-based study is to present the incidence of hospital-treated traumatic brain injury (TBI) in Oslo, Norway, and to describe the severity of brain injuries and outcome of the patients' acute medical care. ⋯ The incidence of hospital-treated TBI in this study is considerably lower than that found in previous studies from Norway and Scandinavia. Despite the apparent decline in TBI hospitalization rates, our findings should also draw attention to the need for more effective preventive programmes related to falls. Studies that assess long-term consequences of TBI in elderly patients are also needed.
