DESCRIPTION (provided by applicant): Motor vehicle collision rates have been shown to fall approximately by half for elderly drivers after cataract surgery. Currently, most insurers allow payment for cataract surgery based upon an individual's self-reported visual difficulties or adverse visual symptoms. As a consequence, surgery tends to occur some time after significant vision problems have emerged. Using data from the Impact of Cataracts on Mobility (ICOM) study and related databases, simulation modeling will be used to examine how many motor vehicle collisions and deaths might be avoided if a threshold measure of vision, contrast sensitivity, were to determine when cataract surgery ought to be performed. The cost effectiveness of such earlier cataract surgery will be examined. A draft guideline will be developed for determining when to perform cataract surgery so as to reduce motor vehicle crashes. This draft guideline will be circulated to professional societies and other stakeholders for their comments, and the simulation model will be rerun to determine the cost effectiveness of any recommended changes. Specific aims of this project are the following: Aim 1: To determine how many motor vehicle collisions would be avoided in the U.S. if threshold vision measurements such as contrast sensitivity were used to determine when cataract surgery ought to be performed; Aim 2: To determine the societal cost effectiveness of earlier cataract surgery compared to current practice; and Aim 3: To develop a draft guideline for cataract surgery that is based upon both patient self-reported visual difficulties and threshold vision measurements. PUBLIC HEALTH RELEVANCE: Motor vehicle collision rates have been shown to fall approximately by half for elderly drivers after cataract surgery. Currently, most insurers allow payment for cataract surgery based upon an individual's self-reported visual difficulties or adverse visual symptoms so that, as a consequence, surgery tends to occur some time after significant vision problems have emerged. Simulation modeling will be used to examine how many motor vehicle collisions and deaths might be avoided if a threshold measure of vision, contrast sensitivity, were used to determine when cataract surgery ought to be performed, and a draft guideline for earlier cataract surgery based on model findings will be developed and circulated for comment.

描述（由申请人提供）：机动车碰撞率已被证明下降约一半的老年司机后，白内障手术。目前，大多数保险公司允许根据个人自我报告的视力困难或不良视力症状支付白内障手术费用。因此，手术往往发生在严重的视力问题出现后一段时间。使用白内障对流动性的影响（IMPACT）研究和相关数据库的数据，模拟建模将被用来检查如果视力阈值测量，对比敏感度，可以避免多少机动车碰撞和死亡，以确定何时应该进行白内障手术。将对这种早期白内障手术的成本效益进行研究。将制定一项准则草案，以确定何时进行白内障手术，从而减少机动车辆碰撞。该指南草案将分发给专业协会和其他利益攸关方，征求他们的意见，并将对模拟模型进行评估，以确定任何建议的更改的成本效益。该项目的具体目标如下：目标1：确定如果使用阈值视力测量（如对比敏感度）来确定何时应进行白内障手术，则在美国可以避免多少起机动车碰撞;目标2：确定与当前实践相比，早期白内障手术的社会成本效益;以及目标3：根据患者自我报告的视力困难和阈值视力测量，制定白内障手术指南草案。 公共卫生相关性：老年司机在白内障手术后，机动车碰撞率已被证明下降了大约一半。目前，大多数保险公司允许根据个人自我报告的视力困难或不良视力症状支付白内障手术费用，因此，手术往往在出现重大视力问题后一段时间进行。模拟模型将被用来检查有多少机动车碰撞和死亡可能会避免，如果阈值测量的视力，对比敏感度，被用来确定何时白内障手术应该进行，和早期白内障手术的指导方针草案的基础上，模型的结果将被开发和分发征求意见。
