Shared Decision-Making for Colorectal Cancer Screening

2014-08-27 03:47:44 | BioPortfolio


The overall objective of this study is to conduct a three-arm randomized controlled trial to evaluate the impact of an interactive, web-based decision aid on shared decision-making and patient adherence to colorectal cancer (CRC) screening recommendations.


Colorectal cancer (CRC) is the second leading cause of cancer-related death and third most commonly diagnosed cancer among men and women in the United States. Screening has been shown to be a cost-effective strategy for reducing both CRC mortality through early detection and incidence through the detection and removal of precancerous adenomatous polyps (adenomas). Despite a compelling rationale and widespread endorsement by authoritative groups, screening rates remain far below those necessary to achieve significant reductions in CRC mortality or incidence. Poor patient acceptance and non-adherence to screening recommendations are partly responsible for low screening rates. Shared decision-making has been advocated as a potentially effective yet unproven strategy for addressing this problem. Implicit in this approach is the need for an unbiased decision aid that not only educates patients about the pros and cons of the different strategies so as to enable them to identify a preferred strategy but also empowers patients to take a proactive role in the decision-making process, thereby increasing satisfaction and promoting adherence. From a logistical standpoint, the decision aid must also be easy to implement in the ambulatory setting so as to maximize use but minimize demands on physician time and office resources. To address this need, we have developed an interactive, web-based decision aid and implementation strategy for use in routine clinical practice.

Comparison(s): Average risk subjects assigned to one of two intervention arms (decision aid alone versus decision aid plus personalized risk assessment with feedback) compared to a control arm(generic website that discusses lifestyle changes that can reduce overall cancer risk).

Medical and Biotech [MESH] Definitions

Tumors or cancer of the COLON or the RECTUM or both. Risk factors for colorectal cancer include chronic ULCERATIVE COLITIS; FAMILIAL POLYPOSIS COLI; exposure to ASBESTOS; and irradiation of the CERVIX UTERI.

Tumor suppressor genes located in the 5q21 region on the long arm of human chromosome 5. The mutation of these genes is associated with the formation of colorectal cancer (MCC stands for mutated in colorectal cancer).

Tumor suppressor genes located in the 18q21-qter region of human chromosome 18. The absence of these genes is associated with the formation of colorectal cancer (DCC stands for deleted in colorectal cancer). The products of these genes show significant homology to neural cell adhesion molecules and other related cell surface glycoproteins.

A group of autosomal-dominant inherited diseases in which COLON CANCER arises in discrete adenomas. Unlike FAMILIAL POLYPOSIS COLI with hundreds of polyps, hereditary nonpolyposis colorectal neoplasms occur much later, in the fourth and fifth decades. HNPCC has been associated with germline mutations in mismatch repair (MMR) genes. It has been subdivided into Lynch syndrome I or site-specific colonic cancer, and LYNCH SYNDROME II which includes extracolonic cancer.

A graphic device used in decision analysis, series of decision options are represented as branches (hierarchical).
