This study examined a problem concerning a surgical instrument decontamination task. Even if Central Sterile Service (CSS) personnel and others responsible for cleaning the operative laparoscopy set were trained, it had been reported that they did not consistently and entirely decontaminate the set. In this study, the actual mistakes during performance of this task, and whether the groups studied were consistent in the mistakes made were described. The effectiveness of the problem-based learning training method and the traditional hands-on method on performance of the decontamination task was also determined. The major gap that this research study addressed was the worker's performance failure compared to training method used. The study may assist in understanding how workers identify and respond to changes in the workplace appropriately since an effective training method will show up in improved workplace performance. Participants were observed performing the decontamination process after application of each training method. Participants were from a community hospital surgical services population that decontaminates surgical instruments as a part of their job and included Registered Nurses, Central Sterile Service technicians, and Surgical Technologists. The participants were randomly assigned to one of two groups, and a crossover method of study was done. Eleven steps in the performance of the task were evaluated, and were designated as Q1 through Q11 in the analysis. Observed errors were tallied, observed performance errors were compared, and effectiveness of training methods was compared and described. It was found that CSS technicians made the fewest errors throughout all observations, and that all groups performed three of the eleven steps of the task correctly (100%) in all observations. It was also found that the hands-on method was more effective for training for the decontamination task than the problem-based learning training method. Although scaffolding, designing to control cognitive load, and provision of ill-structured problems with opportunities for feedback are all important design aspects for building an effective lesson, the first task for design is thorough learner assessment. The challenge is to design training for tasks so well that when studying performance based on training method, performance can be evaluated appropriately.Concord Hospital Central Sterile Supply Department Policy Manual, Policy # DO- 002.
