COMPUTER-BASED VIDEOTAPE ANALYSIS OF TRAUMA RESUSCITATIONS FOR QUALITY ASSURANCE AND CLINICAL RESEARCH

Purpose: To automate time (and motion) studies of major trauma resusci tations. Techniques: We modified an existing time-motion study techniq ue based on time-encoded videotaping for medical imaging workstation h uman factors analysis. Videotapes were recorded of the trauma room dur ing normal clinical activity using an unobtrusive mounted camera. The videotapes are displayed through a customized interface using a Macint osh-based display system. Within this platform, the time-motion study module allows flexible task definition, multiple concordant task assig nment, and various summary result presentations. We established an exp ert panel of two traumatologists, two emergency radiologists, and two time-motion study experts. The expert panel prospectively and uniquely defined important recognizable procedural and cognitive tasks and per sonnel (MD, RN, EMT, RT, etc.) involved in trauma resuscitation based on pilot recordings and collective experience. These task functions we re used to define a menu in the time-motion analysis software. During retrospective videotape review, the beginning and ending times of each task performed were recorded by electronically highlighting each defi ned individual and task. The summary results can be displayed in list, tabular, or graphic form by individuals, personnel classifications, o r tasks.
