e16509 Background: Disparities in colorectal cancer (CRC) outcomes among underrepresented racial and ethnic minority patients continue to widen. We performed, and present here, the results of a systematic review of the literature evaluating interventions to reduce racial and ethnic disparities in CRC care. Methods: The MEDLINE, PsycINFO, CINAHL, and Cochrane databases were searched for articles that focused on interventions to reduce disparities in CRC screening, treatment, survivorship and end-of-life care from 1950 to 2010. Studies included were those that evaluated interventions in US populations that were composed of ≥50% racial/ethnic minorities (or that included a specific sub-analysis by race/ethnicity). Results: Following the electronic search, abstract and full text review, and reference reviews; a total of thirty-three studies were included in our final analysis. All of these were related to CRC screening; no studies evaluating the rest of the cancer care continuum were found. Nineteen studies (58%) were randomized controlled trials, nine (27%) were pre-test/post-test analyses, and five (15%) were cohort studies. Thirteen studies (39%) targeted African-American populations, eight (24%) targeted Hispanics, two (6%) targeted Asian populations, seven (21%) included a mixed population of ethnic minorities, and three (9%) were listed as “non-white” or included a subgroup analysis. The main results related to the magnitude of the effect of these patient-directed, patient navigator, and provider-directed interventions on CRC screening is outlined in the table below. Conclusions: Patient education involving personal contact, patient navigation services, and provider-directed education and reminder systems can modestly improve adherence to CRC screening among minority patients. Further studies targeting the rest of the colon cancer care continuum are needed. [Table: see text]
