Integrating conflicting professional roles: physician participation in randomized clinical trials.

The traditional identification of physicians as either clinician or researcher is challenged by the emergence of randomized clinical trials (RCTs) where research and clinical care are performed simultaneously. A mail survey using a self-administered questionnaire, the Physician Orientation Profile, was conducted of 101 physicians from the Collaborative Ocular Melanoma Study (COMS), a set of trials which compares surgical removal of the eye with radiation in the treatment of medium sized eye cancers. A 95% response rate was obtained; follow-up telephone interviews were conducted with 87% of respondents. Key findings suggest that RCTs challenge traditional definitions of physician's 'core task,' because they participate in a social process that requires them to integrate the formerly disparate and sometimes competing roles of researcher and clinician. Three implications of this integration are discussed: amending the expert reward system, altering customary clinical practice and redefining reference groups for professional interaction.
