The Sleep Reading Center (SRC) for the SHHS will:
Provide centralized training for aspects of SHHS related to the performance of polysomnograms (PSGs).
Provide ongoing technical support for the performance of sleep studies, providing “second line” advice regarding troubleshooting of problem studies (after consultation with local resources), and acting as a liaison with the equipment supplier to identify equipment problems and solutions.
Provide timely review (for quality and medical alerts) and scoring of all records, generating reports needed for participant feedback and data files for central (Coordinating Center - CC) processing.
Provide complete scoring of all sleep studies, with generation of reports that summarize key sleep and respiratory data.
Participate in on-going quality assurance efforts to maintain high levels of scoring accuracy and technical performance of tests at the field sites. These include assistance in trouble-shooting site-specific and study–wide problems, perform site visits, report generation, lead regular conference calls with technicians and members of a Polysomnography SubCommittee.
Produce and archive a clean, edited data set of raw and scored poylsomnographs.
Maintain a data dictionary relevant to polysomnograph variables.
Assess comparability of signals collected for SHHS-2 as compared to SHHS-1.
