 Materials and methods: Patients visiting Pre Admission Testing PAT in anticipation of surgery will be asked if they wish to volunteer for this study. If so they will be asked to review the 10 question multiple choice tutorial on an electronic tablet. If the patients response is incorrect the tablet provides the correct response with an explanation. At the PAT visit the patients name and proposed date of surgery will be obtained. On the day of surgery, these patients will then be given a short questionnaire to assess their knowledge and understanding of the information provided by the tablet exercise. Patients will also be asked to provide demographic information age, gender, race, and highest level of education. Our goal is to obtain 100 anonymous paper surveys. We will compare the survey results of those patients who did not have an opportunity to view the tutorial with those that did to learn whether the tutorial is an effective teaching tool.
