Barriers Driving Racial Disparities in Colorectal Cancer Screening in African Americans.

PURPOSE OF REVIEW: Colorectal cancer screening has been shown to decrease mortality from colorectal cancer. Screening disparities continue to exist among ethnic minorities, particularly for African Americans. We herein review the barriers of colorectal cancer screening in this population. RECENT FINDINGS: At its foundation are patient barriers, which are further compounded by physician-related barriers and the idiosyncrasies of the healthcare system. Interventions to address the barriers include patient outreach, provider education, and healthcare legislation addressing financial barriers. Recent research has focused on factors predicting intentions to undergo colorectal cancer screening. Underlying all of the barriers is the systemic racism that affects and influences the healthcare system as much as all other institutions and contributes to inequities in the delivery of effective cancer prevention efforts. Perpetual disparities in CRC screening within the African American community are due to multifactorial barriers from the individual patient to provider and healthcare system and societal influences. An awareness of the behavioral and systemic factors that affect African Americans must underpin efforts to reach full equity in delivering CRC screening to this often medically underserved segment of our society.

Colorectal cancer screening of high-risk populations: A national survey of physicians.

BACKGROUND: The incidence of colorectal cancer can be decreased by appropriate use of screening modalities. Patients with a family history of colon cancer and of African-American ethnicity are known to be at higher risk of developing colorectal cancer. We aimed to determine if there is a lack of physician knowledge for colorectal cancer screening guidelines based on family history and ethnicity. Between February and April 2009 an anonymous web-based survey was administered to a random sample selected from a national list of 25,000 internists, family physicians and gastroenterologists. A stratified sampling strategy was used to include practitioners from states with high as well as low CRC incidence. All data analyses were performed following data collection in 2009. RESULTS: The average knowledge score was 37 ± 18% among the 512 respondents. Gastroenterologists averaged higher scores compared to internists, and family physicians, p = 0.001. Only 28% of physicians correctly identified the screening initiation point for African-Americans while only 12% of physicians correctly identified the screening initiation point and interval for a patient with a family history of CRC. The most commonly cited barriers to referring high-risk patients for CRC screening were "patient refusal" and "lack of insurance reimbursement." CONCLUSIONS: There is a lack of knowledge amongst physicians of the screening guidelines for high-risk populations, based on family history and ethnicity. Educational programs to improve physician knowledge and to reduce perceived barriers to CRC screening are warranted to address health disparities in colorectal cancer.
