A Sleep Apnea Program for Commercial Drivers



Sleepy driving is a major contributing factor to the motor vehicle crash risk associated with commercial drivers (Pack et al., 2006). In commercial vehicles, approximately 31% to 41% of major crashes can be linked to sleepy driving (Gurubhagavatula et al., 2004). An average non-fatality crash involving a commercial motor vehicle costs about $75,637 while a fatality crash averages about $3.54 million (Gurubhagavatula et al., 2004). A contributing factor to sleepy driving is obstructive sleep apnea (Pack et al., 2006).
The purposes of this study were to: (1) determine how many commercial motor vehicle drivers referred to the sleep center as a result of a positive screen by a commercial motor vehicle driver medical examiner had a true positive test for obstructive sleep apnea, (2) of the number of drivers diagnosed with obstructive sleep apnea at the sleep center, how many met minimum treatment requirements to continue to drive a commercial motor vehicle, and (3) to determine, on average, how long was needed for those commercial motor vehicle drivers to meet minimum treatment requirements using positive airway pressure therapy.
