Laboratory Description:

The Sleep Medicine and Research Center is a specialized center that provides comprehensive evaluation and treatment of the common sleep disorders in our community.
Located at King Abdulaziz University Hospital in Jeddah, Saudi Arabia, the center was initially founded in May 2011 and was expanded following its success in April 2013.
SMRC has a team including a sleep physician, technologists, nurses and researchers, as well as complete access to all medical expertise and facilities at King Abdulaziz University Hospital when needed. This ensures that all our patients get comprehensive and high quality care.
In addition to its diagnostic and therapeutic services, our center takes an active role in educating the public about sleep disorders through seminars and educational activities. Moreover, the center trains physicians and technologists in sleep medicine and has ongoing local research projects. Examples of ongoing research includes OSA in patents with chronic renal failure, rheumatoid, coronary artery disease, and stroke.
We at the SMRC strongly believe in patient education and therefore have devised educational videos and leaflets to be given out to the public. Furthermore, SMRC organised a public awareness campaign in the city of Jeddah.
We hope that this accreditation serves as a bridge between our healthcare world and the people we wish to serve and share our latest news with.
