Patient and Physician Attitudes About Informed Consent for Emergency Department (ED) Computerized Axial Tomography (CT) Scans (CT Consent)

This study has been completed.
Information provided by (Responsible Party):
Marna Rayl Greenberg, Lehigh Valley Hospital Identifier:
First received: August 2, 2010
Last updated: April 25, 2012
Last verified: April 2012

Hypothesis: The majority of Emergency physicians and patients do not feel that specific informed consent should be obtained for ED CT scans.

Secondary Hypothesis: Emergency attending physicians and residents will have similar attitudes about CT scan consent issues. Physician attitudes toward obtaining consent for CT scans will change after an educational program about the associated risks.

    Before and after education physicians will be surveyed as to the attitudes about ordering ct's

Enrollment: 77
Study Start Date: August 2009
Study Completion Date: December 2010
Primary Completion Date: December 2010 (Final data collection date for primary outcome measure)
Intervention Details:
    Other: Educational session
    Physicians will have a brief education session provided in powerpoint about the risks of CT
Detailed Description:

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.

ED attendings who do not attend grand rounds will only be asked to complete the first portion of the survey (Figure 1, example A). Resident or attending consent to participate will not be coerced, and participation will be implied by completion of the survey.
