Colorectal cancer CRC is the second leading cause of cancer deaths in the United States. CRC might be prevented with screening, but there are several screening options, each with risks and benefits. Current recommendations encourage providers to share decision-making with patients to weigh risks, benefits and uncertainties. The use of decision aids has been widely advocated as an effective means for patients and providers to reach agreement when there are two or more valid treatment choices, such as in the case of CRC screening. This study was designed to determine the quality of CRC screening decisions when a formal decision aid was available. In order to examine the quality of colon cancer screening decisions, both with and without the use of a decision aid, 280 study participants were randomly assigned to receive usual care n 140 or a video about colon cancer and screening options n 140. Participants in the intervention group received information on risks and benefits of all available screening options. Usual care participants received standard care without the decision aid.
