The Harvard Medical School released a report in 2010 entitled, "The Price of Fatigue: The Surprising Economic Costs of Unmanaged Sleep Apnea," in which it estimated the annual economic cost of moderate to severe OSA in the United States to be $65-165B (compared to $60B for drunk driving and $150B for not wearing seatbelts), including $10-40B in OSA-related traffic accidents and $5-20B in OSA-related workplace accidents (10).
