  • Title: Barriers to colorectal cancer screening among Medicare consumers.
    Author: Klabunde CN, Schenck AP, Davis WW.
    Journal: Am J Prev Med; 2006 Apr; 30(4):313-9. PubMed ID: 16530618.
    Abstract:
    BACKGROUND: Few studies have examined lack of physician recommendation and other reasons for under-utilization of colorectal cancer (CRC) screening in the Medicare population. METHODS: Data from a telephone survey conducted in 2001 in a random sample of Medicare consumers residing in North and South Carolina were used to examine barriers to CRC screening, focusing on consumers' reports of receiving a physician's recommendation to obtain CRC screening and reasons for not being screened. Analyses were restricted to respondents with no history of CRC (n = 1901). Descriptive statistics were used to characterize respondents' CRC screening status, receipt of a physician's recommendation for screening, and reasons for not being screened. Logistic regression modeling was used to examine factors associated with receiving a physician recommendation for fecal occult blood test, sigmoidoscopy, colonoscopy, any endoscopy, and any CRC test. RESULTS: Thirty-one percent of Medicare consumers had never been tested for CRC, and 18% had been tested but were not current with Medicare-covered intervals. Overall, 28% reported not receiving a physician recommendation for screening. Predictors of receiving a physician recommendation included sociodemographic (younger age, white race, more education), health status (increased CRC risk, comorbidity), and healthcare access (had a routine/preventive care visit in the past 12 months) factors. Lack of knowledge/awareness and the physician not ordering the test were commonly cited reasons for not having CRC tests. CONCLUSIONS: Colorectal cancer screening was under-utilized by Medicare consumers in two states, and lack of physician recommendation was an important contributing factor. Providing a benefit under the Medicare program does not ensure its widespread use by consumers or their physicians.
