重症頭部外傷における年齢構成の推移 ： 頭部外傷データバンク【プロジェクト1998, 2004, 2009, 2015】の変遷

抄録

This study documents the epidemiology of severe head injury in Japan based on the projects conducted by Japan Neurotrauma Data Bank Committee. Four projects, named as Project 1998, 2004, 2009, and 2015, were completed so far to compare the age distribution of patients, cause of head injury, pathophysiology, and outcome among projects. In Project 2015, 1) the average age of patients was getting older over the projects, 2) the peak occurrence of severe head injury shifted to older than 80 years, 3) the rate of elderly pedestrian injury increased in traffic accidents, 4) falling on the ground increased as a cause of injury, 5) mortality rate increased with age, as well as prior projects. In conclusion, these epidemiological data will help us to prevent severe head injury in the future.
