THE INTEGRATION OF PERFORMANCE LOGS WITH DIGITAL VIDEO FOR REVIEW OF SIMULATION TRAINING SESSIONS John W. Lutz, Thomas Dongilli, John J. Schaefer III University of Pittsburgh Medical Center (UPMC), Peter M. Winter Institute for Simulation Education and Research (WISER) Pittsburgh, PA 15261 ABSTRACT BACKGROUND METHODS METHODS Background Full scale simulati on educati on sessions are often recorded using There are preliminary versions of software available that allows An example of a video log linked to the Full-scale simulati on educati on sessions are often recorded using standard videotape for playback during post-session debriefing. digital video recording on a central server with playback Rewinding and queuing the video tape to the appropriate spot to digital video recording taken during that standard videotape for playback during post-session debriefing. available through a customized ActiveX™ object over the make educational points can be time consuming and frustrating Use of the Laerdal SimMan Simulator allows automatic Internet via a standard web browser.
