OBJECTIVE: Results of prehospital pediatric continuing education using train-the-trainer and CD-ROM training methods were compared to each other and to a control group. The null hypothesis was that no differences would be found in pretraining and posttraining measurements of knowledge and performance by either training method. METHODS: This was a prospective trial involving 12 sites. Random selections were made from ambulance service lists provided by 3-state emergency medical services (EMS) agencies. Preintervention and postintervention (12-month) measurements included a written examination and 2 performance scenarios videotaped for independent panel evaluation. Training was either an interactive CD-ROM or standard classroom instruction using a train-the-trainer model. Mean differences in written, performance, and combined scores were analyzed. RESULTS: Differences were noted in the combined and performance scores for the CD-ROM intervention group. No differences were noted in written measurements between or among the groups. CONCLUSION: In this small sample, interactive CD-ROM training shows promise for improving performance. The research design, with additional guards against sample size attrition, may provide a model for multisite EMS education research.

For storage of large amounts of data, there are many options to consider, including both CD and DVD methods. Given that these are now becoming very cheap alternatives, and that we work in a specialty which generates large volumes of digital data, it is now obvious why CD and DVD burning is of interest to radiologists. These technologies can most assuredly be of great benefit to both our professional and personal lives.
