PATIENTS AND METHODS The High(More)
OBJECTIVE Colorectal cancer (CRC) screening uptake remains poor. Until we understand patient motivation and preferences for undertaking screening, it is unlikely the uptake will be optimal. Our objective is to examine patient preferences for CRC screening modalities and uptake rates using utility-based methods. METHODS The preference survey was mailed to(More)
OBJECTIVE The behavioral model of utilization, developed by Andersen, Aday, and others, is one of the most frequently used frameworks for analyzing the factors that are associated with patient utilization of healthcare services. However, the use of the model for examining the context within which utilization occurs-the role of the environment and(More)
BACKGROUND Testing has been advocated for all persons with newly diagnosed colorectal cancer to identify families with the Lynch syndrome, an autosomal dominant cancer-predisposition syndrome that is a paradigm for personalized medicine. OBJECTIVE To estimate the effectiveness and cost-effectiveness of strategies to identify the Lynch syndrome, with(More)

OBJECTIVE To evaluate the(More)
