ED residents and ED attendings who attend grand rounds will be given a survey and asked to anonymously complete the first portion before grand rounds (Figure 1, example A). The first portion will assess basic demographics, CT ordering patterns and experiences, and attitudes about informed consent. They will be provided with an educational program at grand rounds that reviews current literature relevant to CT utilization and consent issues. After the lecture they will be asked to complete the second section of the survey (Figure 1, Example B). Both portions of the survey will be simultaneously returned in a sealed envelope and placed in a collection box at grand rounds.
