Biography Historical Article Classical ArticleEffectiveness of a simulator in training anesthesiology residents. 1969.
The educational potential of a computer-controlled patient simulator was tested by the University of Southern California School of Medicine. The results of the experiment suggest unequivocally that there is a twofold advantage to the use of such a simulator in training anesthesiology residents in the skill of endotracheal intubation: (a) residents achieve proficiency levels in a smaller number of elapsed days of training, thus effecting a saving of time in the training of personnel, and (b) residents achieve a proficiency level in a smaller number of trials in the operating room, thus posing significantly less threat to patient safety. The small number of subjects in the study and the large within-group variability were responsible for a lack of statistical significance in 4 of 6 of the analyses performed; however, all differences were substantial and in the hypothesized direction. Thus, despite the narrowly circumscribed tasks to be learned by the experimental subjects, the findings suggest that the use of simulation devices should be considered in planning for future education and training not only in medicine but in other health care professions as well.

Communication failures in the operating room: an observational classification of recurrent types and effects.
Ineffective team communication is frequently at the root of medical error. The objective of this study was to describe the characteristics of communication failures in the operating room (OR) and to classify their effects. This study was part of a larger project to develop a team checklist to improve communication in the OR. ⋯ Communication failures in the OR exhibited a common set of problems. They occurred in approximately 30% of team exchanges and a third of these resulted in effects which jeopardized patient safety by increasing cognitive load, interrupting routine, and increasing tension in the OR.

The simulated operating theatre: comprehensive training for surgical teams.
Surgical excellence is traditionally defined in terms of technical performance, with little regard for the importance of interpersonal communication and leadership skills. Studies in the aviation industry have stressed the role of human factors in causing error and, in an attempt to reduce the occurrence of adverse events, led to the organisation of simulation based training scenarios. ⋯ The scenarios have good face validity and junior surgeons can benefit from the process of learning new technical skills in a realistic environment. The effect of external influences such as distractions, new technology, or a crisis scenario can also be defined, with the ultimate aim of reducing the number of adverse events arising in the real operating room.

Objective measures of situation awareness in a simulated medical environment.
One major limitation in the use of human patient simulators is a lack of objective, validated measures of human performance. Objective measures are necessary if simulators are to be used to evaluate the skills and training of medical practitioners and teams or to evaluate the impact of new processes or equipment design on overall system performance. Situation awareness (SA) refers to a person's perception and understanding of their dynamic environment. ⋯ An objective measure of SA may be more sensitive and diagnostic than traditional performance measures. This paper reviews a theory of SA and discusses the methods required for developing an objective measure of SA within the context of a simulated medical environment. Analysis and interpretation of SA data for both individual and team performance in health care are also presented.

In the field of medicine, team training aiming at improving team skills such as leadership, communication, co-operation, and followership at the individual and the team level seems to reduce risk of serious events and therefore increase patient safety. The preferred educational method for this type of training is simulation. ⋯ The use of this framework is illustrated by the present multiprofessional team training in advanced cardiac life support, trauma team training and neonatal resuscitation in Denmark. The challenges of addressing all aspects of team skills, the education of the facilitators, and establishment of evaluation strategies to document the effect of the different types of training on patient safety are discussed.
