Abstract

Matching training in ultrasound to trainee prior knowledge

Sharon Yogev, Ronnie Tepper, Daniel Gopher.

Introduction: “Simultech” is a simulation training facility for OB/GYN US in the Meir medical center, Israel which administers training on a computerized platform developed to endow physicians and sonographers with updated knowledge and operation skills of obstetric ultrasound (US). The present study was conducted on fellows and residents who use ultrasound in their daily work. Most of them participate yearly in one day training and refreshment of US knowledge and skills. Accordingly, the content and focus of training should be properly matched to their experience and existing knowledge. The present study investigated the usefulness of introducing formal tools to evaluate prior knowledge, formulate training and assess the effect of the training day. Those have been dealt with thus far informally, through individual conversations between a trainee and an instructor before and during training followed by trainee's written comments.

Methods: Three tools were developed to evaluate prior knowledge, performance and training: 1) Activity profile form -Trainees were first asked to describe the daily profile of their US work; 2) Subjective Evaluation - A subjective evaluation questionnaire rating their competence in US topics: 3) Case study tests - Trainees performed one simulated case study analysis at the beginning and one at the end of the training day.  Forty two physicians participated in the study. New matching protocols was formulated for one half while the other half received the previous format and mix of cases and topics.  Matching was performed such that trainees were presented with difficult or easy cases and questions, based on their prior subjective evaluation of their knowledge.

Results: The results show that subjective evaluations significantly linked and correlated with performance of the entry case study, but not with the more difficult case given at the end of the day. For both groups post-training case analysis test scores were higher than those of the pre-training test. The efficiency of the new matching protocol interacted with trainees' activity profile, such that matching based of subjective ratings, was more efficient for US topics which were performed more frequently on a daily base. On less experienced topic the existing mix of easy, medium and difficult cases was more effective.  

Conclusion:  Systematic assessment of prior knowledge and competence based on daily activity profiles and subjective rating provide important information for the design and conduct of training of experienced trainees.
