Sleep disorders, i.e. diseases that affect, disrupt or involve sleep, represent major challenges for physicians and healthcare systems worldwide. The high prevalence, the complexity and the health burden of sleep disorders demand the establishment of specific clinical sleep centres where adequate and efficient diagnosis and management of patients with such diseases can be provided. This document describes practice guidelines for standards of adult sleep medicine centres in Ireland. These guidelines are the result of a consensus procedure in which all committee members of the Irish Sleep Society (ISS) were involved. The scope of these guidelines is to define the requirements of sleep medicine services, in terms of personnel, facilities, equipment and procedures.
