Abstract

Purpose: We surveyed ordering physician attitudes, knowledge, and behavior with regard to computed tomography (CT)-related radiation exposure at a large medical center. Methods: Sixteen questions were sent via electronic survey to 350 physicians. Results and conclusion: The ability to quickly rule in or rule out conditions effectively strongly influenced the decision to order CT (85%-99%). Fear of litigation influenced CT ordering for those with less experience [odds ratio (OR)=2.3, P<.05]. Residents and primary care physicians were less likely to discuss risks/benefits of CT with patients (P≤.03) compared to those with >5 years of experience (OR=4.0, P=04).
