OBJECTIVE: This presentation will describe the range and quality of vision- related information submitted to the Driver License Bureau, Missouri Department of Revenue, for older drivers reported as unfit in 2001-2005.
METHODS: With funding support from the AAA Foundation for Traffic Safety, all available medical and testing data from a sample of reported drivers, age 50+, from 2001-2005 (n = 4,100) was collected from microfilm and analyzed relative to retrospective/prospective crash data and final licensing outcome. Only the most basic vision data was included in a 2008 project report published through AAAFTS. The current presentation will re- view all available vision information, including specific diagnoses, acuity, visual fields, etc.
RESULTS: The presentation will highlight shortcomings in the driver evaluation system, such that incomplete and/or inconsistent data were used in many cases to determine driver license status. A grading system for data quality will be discussed.
CONCLUSIONS: While Missouri has an effective voluntary reporting and review system for older drivers, the current means to collect and review vision data is flawed. A number of recommendations will be discussed to improve data flow and quality for this State and others. |
