Sleep: At The Wheel With Sleep Apnea! (cont.)
"It is estimated that as many as 40 million Americans have undiagnosed sleep apnea," said the paper's senior author, Terence Davidson, M.D., professor of surgery, UCSD Division of Otolaryngology-Head and Neck Surgery. "Dr Sassani's study clearly demonstrates that these people are falling asleep while driving, killing themselves and innocent bystanders. It is time for American Medicine and the American people to wake up to sleep."
The UCSD investigators noted the prevalence of obstructed sleep apnea in drivers is estimated at 3 percent, or 4.7 million drivers. A recent study of 1,391 commercial truck drivers found that 28 percent had obstructive sleep apnea, with more than one-third characterized as moderate to severe. Sassani indicated that in one year alone - the year 2000 - more than 800,000 drivers with the condition were involved in motor-vehicle accidents.
The researchers estimate that 980 of the 1,400 fatalities each year will be avoided with treatment, based on a 70 percent CPAP success rate. While the annual cost of treating sleep apnea patients is approximately $3.18 billion, including screening costs, the researchers noted that collision costs for accidents caused by sleep apnea patients were $15.9 billion annually. These collision costs would be reduced annually by $11.1 billion, using a 70 percent effectiveness rate.
Furthermore, the study investigators added that
the savings from CPAP treatment "do not take into account the other economic,
medical and social benefits of treating obstructive sleep apnea syndrome,
including decreased accidents at work, decreased hospitalization costs, and the
improved quality of life."
According to Davidson, "It is noteworthy that this study was made possible by a $2,000 educational grant from a local sleep company, ResMed, to Dr. Sassani when he was a UCSD medical student. This is an exemplary example of how the business community and the university can partner to make good things happen."
