Colorectal cancer screening among midwestern community-based residents: indicators of success.
Screening reduces the rate of death and morbidity resulting from CRC. Although CRC screening rates are low relative to other cancer screening tests, rates appear to be increasing: In 2004, 57% of adults > or =50 years reported up-to-date CRC screening test use; 14 states and Washington DC showed rates in excess of 60%. Identification of indicators of success and challenges remaining are important for universal goal achievement. The purpose of this study was to identify system and individual-level indicators of up-to-date CRC screening in a geographic area that reports higher uptake rates. Random-digit-dialing methods were used to survey a population-based community sample (N = 1033) of Midwestern adults ages 50 to 79 for CRC screening uptake in spring 2005. Adjusted odds ratio estimates were obtained using multivariate logistic regression. In total, about 62.6% of the sample reported up-to-date CRC screening. Compliant attitudes toward physicians' screening recommendations were important indicators for up-to-date CRC screening; other individual-level psychosocial factors included beliefs about testing responsibility and testing safety. Non-current CRC screening was linked with testing anxiety and lack of perceived need for healthy people to test. System-level indicators associated with up-to-date CRC screening included reliance on physicians as the primary source for health information, family/personal history of bowel disease, regular physician visits, and participation in other cancer screening tests, controlling for age. Although population-based studies generally emphasize health system-level factors, individual-level attitudes such as feelings of responsibility to screen and adherence to physicians' screening recommendations are important contributors to up-to-date CRC screening patterns.
