Perspectives on the Value of Advanced Medical Imaging: A National Survey of Primary Care Physicians

PurposeTo understand perceptions of primary care physicians (PCPs) about the value of advanced medical imaging.MethodsA national quantitative survey of 500 PCPs was conducted using an online self-administered questionnaire. Questions focused on advanced medical imaging (CT, MRI, and PET) and its perceived impact on the delivery of patient care. Responses were stratified by physician demographics.ResultsLarge majorities of the PCPs indicated that advanced imaging increases their diagnostic confidence (441; 88%); provides data not otherwise available (451; 90%); permits better clinical decision making (440; 88%); increases confidence in treatment choices (438; 88%), and shortens time to definitive diagnosis (430; 86%]). Most (424; 85%) believe that patient care would be negatively affected without access to advanced imaging. PCPs whose clinical careers predated the proliferation of advanced imaging modalities (>20 years of practice) assigned higher value to advanced imaging on several dimensions compared with younger physicians whose training overlapped widespread technology availability.ConclusionsBy a variety of metrics, large majorities of PCPs believe that advanced medical imaging provides considerable value to patient care. Those whose careers predated the widespread availability of advanced imaging tended to associate it with even higher value.
