Effect of Interactive Video Practice in Detecting Technical Errors on Performance of a Simple Medical Procedure.
Abstract
Recent developments in the field of instructional media provide educators with enhanced technological capabilities to teach procedures involving psychomotor skills. A general model for using an interactive video instruction (IVI) program to teach a simple medical procedure, aseptic degloving, was tested as a supplemental instruction tool. Seventy-six Navy Hospital Corpsmen enrolled in the Basic School, Naval School of Health Sciences, served as subjects. The design of the degloving module involved demonstration of the correct technique. The learners were then tested on their ability to observe errors in trial examples of the procedure. This strategy was developed to enhance successful memory of the procedural sequence, related principles, and subsequent actual performance. Three experimental groups were formed. Subjects viewed either the IVI lesson, a linear videotape of the same content, or received no supplemental instruction (control group). The outcome measure was a videotaped performance test which required the subjects to deglove aseptically five times in succession. The number of errors committed each trial by the subject were evaluated by two independent registered nurse judges.
