Colorectal cancer screening among African Americans: the importance of physician recommendation

African Americans have higher colorectal cancer incidence and mortality rates than whites. They are also more likely to be diagnosed with late-stage disease and less likely to survive for at least five years after diagnosis. Lack of adherence to colorectal cancer screening recommendations has previously been found to be associated with lower income, lower educational level, and racial/ethnic minority status. One hundred-fifty African-American patients (aged 50-79 years) of an inner city hospital, were surveyed by mail and telephone in early 2002. Seventy-six patients completed the survey, and data from 74 surveys were analyzed. Approximately one-half (55%) of the respondents reported having received a fecal occult blood test (FOBT) in the last 12 months, sigmoidoscopy in the last five years, or colonoscopy in the last 10 years. Thirty-nine percent of the survey participants reported never having received a physician recommendation for FOBT, 60% reported never having received a recommendation for sigmoidoscopy, and 57% reported never having received a recommendation for colonoscopy. Previous physician recommendation was strongly associated (p < 0.001) with levels of FOBT, sigmoidoscopy, and colonoscopy use. Future studies should examine factors that influence primary care physicians' decision-making about ordering colorectal cancer screening tests, as well as patients' decision-making regarding adherence to physician recommendations.
