Colorectal cancer screening in African Americans: practice patterns in the United States. Are we doing enough?

Background: Colorectal cancer (CRC) is a common form of malignancy and a leading cause of death in the United States. Screening decreases CRC incidence and mortality. African Americans are at an increased risk of developing CRC, and recommendations are to initiate screening at the age of 45. This study aims to assess the rate of screening for colorectal cancer in African Americans between the ages of 45–49. Methods: African Americans between the ages of 45–49 were identified in the Explorys national database. Patients who completed a colonoscopy, sigmoidoscopy or fecal occult blood test were identified and stratified by sex and insurance status. A P value < 0.05 was considered significant. Results: A total of 181 200 African Americans were identified as eligible for screening. Only 31 480 patients (17.4%) received at least one screening procedure for CRC. The majority of patients (66.7%) were screened via colonoscopy. African American females were more likely to complete a screening test (17.8% vs 16.7%; P < 0.01). The majority of patients (66.0%) who completed a screening test had private insurance. Conclusion: Race, gender and barriers to medical care contribute to disparities in CRC screening rates. Among African Americans, CRC screening remains suboptimal. Tailored public health initiatives, medical record alerts and improved communication between providers and patients are fundamental to addressing issues that impact poor adherence to CRC screening in African Americans.
