All sessions in the sim lab are videotaped automatically. All videotapes sessions titles are not identified by name but coded (i.e sim session medical code session 6 June 08). All videotapes are reviewed periodically and deleted except for few that are kept for educational purpose. These videotapes are identified by subject study number and phase only (i.e. CVLN 01 phase 1). In this project, videotaping of all subjects performances is for the purpose of training, and quality improvement. The research part of this project involves review of the data collected by the instructor on the assessment tool and is unrelated to videotaping.
