In Alberta, Canada, while standards have been in place for overnight sleep medicine clinics since the 1990s, until now labs offering take-home sleep apnea tests and treatment were not subject to similar rules, reports CBC.

“The quality of care issues [are] disastrous,” said Dr. Charles Samuels, medical director of the Calgary-based Centre for Sleep and Human Performance and president of the Canadian Sleep Society, an organization that promotes sleep disorders medicine and education.

“We’re seeing terrible problems and poor treatment that should never occur.”
