The UM sleep medicine program is one of the oldest, largest, and most well-developed in the U.S. This multidisciplinary group includes physicians from Neurology, Pediatrics, Medicine (Pulmonary), Otolaryngology, Oral and Maxillofacial Surgery, and Psychiatry who see outpatients with any complaints related to sleep or alertness, and operates 3 sleep laboratories with a combined total of 28 sleep laboratory beds. These three centers, equipped with state-of-the-art digital sleep recording equipment, and highly specialized capabilities including esophageal pressure monitoring, end-tidal and transcutaneous carbon dioxide monitoring, and full EEG montages, perform more than 7000 sleep laboratory studies, and a growing number of home sleep apnea studies each year. In addition to the general sleep disorders clinics, several more specialized and also multidisciplinary clinics have been established to provide the most effective care. These include pediatric sleep disorders clinics as well as a multidisciplinary pediatric sleep and behavior clinic, in which a family sees two types of specialists at one visit. A robust behavioral sleep medicine program, mainly for patients with chronic insomnia, offers an initial evaluation with a sleep physician as well as a sleep psychologist, both of the same visit. Finally, the Sleep Disorders Center maintains an active inpatient consultation service, and can provide bedside attended polysomnography for hospitalized patients when indicated.
