Purpose:
Medical students must be competent in basic aseptic technique (BAT) to function effectively in the operating room. However, a comprehensive literature review revealed a deficit of research in standardized BAT training for the operating room in medical school curricula.
Methods:
A modified reactive Delphi technique was used to survey an expert panel of 100 surgical educators. A focus group provided initial responses to key questions, and the panel completed 2 surveys. In the first survey, the panel identified elements for a BAT curriculum for the operating room. In the second survey, the panel received feedback from the first survey and was asked to respond in light of those results.
Results:
An 81% response rate was obtained from the first survey. A 74% response rate was obtained from the second survey. Seven of the 18 essential entry-level competencies (EELCs) identified were ranked as the most important. The top 5 instructional strategies and the top 3 methods for evaluation were also selected. The panel identified the third-year curriculum as the preferred time of training and a nurse preceptor/educator as the preferred instructor.
Conclusions:
These results provide a minimum set of educational objectives that can be used to develop a standardized curriculum in BAT for the operating room for medical students.

Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
