6.1 Objectives

The Case Western Reserve University Polysomnography Reading Center (PRC) will:

• Work with study investigators to select sleep monitoring devices and recording montage most appropriate for meeting the study goals.
• Develop a standardized protocol for data acquisition, processing, scoring, and urgent alert identification.
• Provide training for technicians, research assistants and study coordinators for collection field sites, dedicated to sleep study acquisition, staff certification, and data transmission to PRC.
• Provide ongoing technical feedback to study sites relative to acquisition of sleep data.
• Monitor the quality of submitted sleep studies; assign quality codes; report findings of study quality and performance to study investigators.
• Review and score sleep studies by certified scorers, following a standardized protocol.
• Establish routines for reporting results to the DCC and clinical sites.
• Monitor the quality of central reading and scoring.
• Generate electronic reports from scored records; prepare customized data files for data analysis; transmit these reports periodically to the DCC analysis center.
