“We are spending more and more money on sleep testing and treatment, and like anything else in health care, there are unscrupulous people out there who are more than happy to do testing and treatment that might be of questionable value.”

"This is a good example of something where we have technology, we have financial incentives to use more of it ... You have enough problems, including a growing obesity epidemic, and you sort of put together the so-called perfect storm for driving up overuse and health care costs.”

"I believe lab tests, as opposed to the home tests, are being wildly overprescribed…it should be 70 percent at home and 30 percent in the lab.”

Sleep & obesity in the U.S.

Obesity is the strongest risk factor for obstructive sleep apnea (OSA)

Each increase of 10 kg in weight doubles the risk of OSA

OSA contributes to weight gain causing a vicious cycle

The future of our field will be dictated by our ability to show how our services add value to the healthcare enterprise.

We must focus on short and long-term outcomes and design our practices to maximize best outcomes.

We must see the evolving changes as an opportunity to fulfill the promise of better sleep.
