Determine (1) the sensitivity of world-wide-web searches for deaths among persons with traumatic brain injuries and (2) factors associated with the likelihood of identifying deceased persons with traumatic brain injuries.
Stratified case series.
Sequential submission of 371 deceased persons with traumatic brain injuries to a world-wide-web site to determine inclusion in the Social Security Death Index (SSDI).
Almost 87% of deceased persons ages 50+ were found, 69.8% of persons ages 30-49 and 34.6% of persons younger than age 30. Other factors influencing the likelihood of finding deceased persons in the SSDI were male gender, white race, being married, knowing the Social Security number and survival of 1+ years post-injury.
The SSDI provides useful information for mortality studies among persons with traumatic brain injuries, but does a poor job of identifying deaths among younger persons. Sole reliance on the SSDI may result in under-ascertainment of mortality.
确定（1）通过互联网搜索创伤性脑损伤患者死亡情况的敏感性，以及（2）与识别创伤性脑损伤死者可能性相关的因素。
分层病例系列。
将371名创伤性脑损伤死者依次提交至一个网站，以确定其是否被纳入社会保障死亡指数（SSDI）。
50岁及以上死者中近87%被找到，30 - 49岁者中69.8%被找到，30岁以下者中34.6%被找到。影响在SSDI中找到死者可能性的其他因素包括男性、白人种族、已婚、知晓社会保障号码以及受伤后存活1年及以上。
SSDI为创伤性脑损伤患者的死亡率研究提供了有用信息，但在识别年轻患者死亡情况方面表现不佳。仅依靠SSDI可能导致死亡率漏报。
