Background
Despite the documented benefits of colorectal cancer screening, patient participation rates remain low. Physician recommendation
has been identified as a significant predictor of screening completion.
Objective
The aim of this study is to investigate how primary care physicians perceive colorectal cancer screening communication tasks,
as well as to explore the form and content of actual screening discussions.
Design
The research design includes a mailed physician survey and a separate observational study in a sample of videotaped medical
encounters.
Participants and Data Sources
The participants were 270 primary care physicians who completed a mailed questionnaire (57.9% response rate) and 18 physician–patient
encounters that included discussions of colorectal cancer screening.
Measurement
The questionnaire focused on perceived importance and accomplishment of communication tasks relevant to colorectal cancer
screening. Two of the authors reviewed transcripts of videotaped physician encounters to determine whether the same communication
tasks assessed in the survey were accomplished. Interrater reliability was high across all of the mutually exclusive coding
categories (Kappa > .90).
Results
Physicians rated colonoscopy as the most important screening option to discuss; self-reports indicate that colonoscopy (84.8%)
is more frequently mentioned than fecal occult blood test (FOBT; 49.4%), flexible sigmoidoscopy (34.1%), or computed tomography
(CT) imaging (18.1%). Explaining benefits and risks, describing test procedure and frequency, eliciting patient preferences,
and making a plan for screening were all viewed as very important. Self-reported accomplishment of these communication tasks
was considerably higher than that observed in our separate videotape sample.
Conclusion
Most physicians recognize and espouse the importance of recommending colorectal cancer screening to eligible patients. However,
findings from both the physician survey and observational study suggest that physicians tend to overestimate the extent of
discussions about screening. Interventions may be warranted to improve clinical practice.
