One of the key issues surrounding the management of OSA is driver fatigue; whether the patient has an undiagnosed sleep disorder, or is non-compliant on their CPAP treatment. It has been estimated that such drivers are between 6 and 15 times more likely to have a road traffic accident than those without the condition. Driver fatigue and sleepiness is a serious problem resulting in many thousands of road accidents each year. Impaired concentration as a result of being sleepy at the wheel increases the chances of a Motor Vehicle Collision significantly.
