Gowning training: the use of video recording together with microbial assessment

Following classroom training on proper aseptic gowning technique, clean room operators were filmed while gowning according to standard procedure. Subsequently, the exterior surface of each operator's gown was monitored for microbial contamination. Operators reviewed their personal videotaping with the trainer. Through careful and critical self-observation, the operator's ability to follow the gowning procedure in addition to using good gowning technique was ascertained. Furthermore, the operator's gowning technique was compared with the results of the microbiological monitoring data. A correlation between microbial contamination of the gown surface and improper technique was demonstrated. This correlation enhanced the operator's awareness of the consequences of improper gowning technique. Use of video replay enabled the operator and trainer to identify improper or subtle flaws in technique detected through microbial monitoring but undetected during actual gowning. This training program served to further emphasize the importance of using proper aseptic gowning technique. Clean room operators are more involved in maintaining clean room integrity and their awareness of the potential for contaminating the area by inadequate technique has been enhanced.
