Project Summary:

The purpose of the commercial driver's medical examination (CDME) is to screen drivers for safety-relevant medical conditions and identify those who have conditions that could affect their ability to safely operate commercial motor vehicles. The Federal Motor Carrier Safety Administration (FMCSA) instituted a Registry of Certified Medical Examiners and specified training standards for examiners for the first time in 2014. It also revised the CDME examination form in 2015 due to concerns about the effectiveness of the CDME. The Truckers & Turnover Project has access to CDME data on several thousand drivers along with separate medical diagnosis information on the same individuals, for a pre-Registry period, and has the ability to acquire similar data for a post-Registry period. Task One is to analyze pre-Registry data to establish the first-ever formal benchmark for the screening effectiveness of the original CDME with regard to specific, safety-relevant medical conditions (obstructive sleep apnea (OSA) and between one and three other conditions, such as hypertension). Task Two is to acquire data and construct a data set based on post-Registry data from the same motor carrier,and prepare an exploratory analysis of this data set in preparation for submitting a proposal to the FMCSA to fund a future companion study of the screening effectiveness of the post-Registry CDME.
