To determine the circumstances under which persons with dementia become lost while driving, how missing drivers are found, and how Silver Alert notifications are instrumental in those discoveries.
A retrospective, descriptive study.
Retrospective record review.
Conducted using 156 records from the Florida Silver Alert program for October 2008 through May 2010. These alerts were issued in Florida for missing drivers with dementia.
Information derived from the reports on characteristics of the missing driver, antecedents to missing event, and discovery of a missing driver.
The majority of missing drivers were men aged 58 to 94 who were being cared for by a spouse. Most drivers became lost on routine, caregiver-sanctioned trips to usual locations. Only 15% were driving when found, with most being found in or near a parked car. Law enforcement officers found the large majority. Only 40% were found in the county where they went missing, and 10% were found in a different state.
Silver Alert notifications were most effective for law enforcement; citizen alerts resulted in a few discoveries. There was 5% mortality in the study population, with those living alone more likely to be found dead than alive. An additional 15% were found in dangerous situations such as stopped on railroad tracks. Thirty-two percent had documented driving or other dangerous errors, such as driving the wrong way or into secluded areas or walking in or near roadways.
确定痴呆症患者在驾驶时迷路的情况，失踪驾驶员是如何被找到的，以及银警报通知在这些发现中是如何发挥作用的。
回顾性描述性研究。
回顾性记录回顾。
使用 2008 年 10 月至 2010 年 5 月佛罗里达州银警报计划的 156 份记录进行了研究。这些警报是在佛罗里达州发布的，针对患有痴呆症的失踪驾驶员。
从失踪驾驶员的特征报告、失踪事件的前因和失踪驾驶员的发现中得出信息。
大多数失踪驾驶员是年龄在 58 至 94 岁之间的男性，他们由配偶照顾。大多数司机在常规、经护理人员批准的常规旅行中迷路。只有 15%的人在被发现时在开车，大多数人是在或靠近停放的汽车中被发现的。大多数是执法人员发现的。只有 40%的人是在他们失踪的县找到的，10%的人是在不同的州找到的。
银警报通知对执法部门最有效；公民警报导致了一些发现。在研究人群中，有 5%的死亡率，独居者比活着的人更有可能被发现死亡。另外 15%的人被发现处于危险境地，如停在铁轨上。32%的人有记录在案的驾驶或其他危险错误，如逆行或进入僻静区域或在道路上行走或靠近道路。
