Computer-based videotape analysis of trauma resuscitations for quality assurance and clinical research.

Purpose: To automate time (and motion) studies of major trauma resuscitations. Techniques: We modified an existing time-motion study technique based on time-encoded videotaping for medical imaging workstation human factors analysis. Videotapes were recorded of the trauma room during normal clinical activity using an unobtrusive mounted camera. The videotapes are displayed through a customized Interface using a Macintosh-based display system. Within this platform, the time-motion study module allows flexible task definition, multiple concordant task assignment, and various summary result presentations. We established an expert panel of two traumatologists, two emergency radiologists, and two time-motion study experts
