Patient characteristics, healthcare utilization practices and rural-urban residence associated with accurate self-report of up-to-date colorectal cancer screening by colonoscopy
Methods: 1,399 patients, aged 51-80, from 16 Midwestern family medicine offices, completed an investigator-developed questionnaire. We compared self-report of up-to-date screening with test documentation in the medical record to measure concordance. Patient's place of residence was categorized according to Rural Urban Commuting Area (RUCA) codes ("metropolitan" [population 50,000+], "large rural" [10,000-49,999], "small town" [2,500-9,999] or "rural area" [<2,500]). Multivariable analysis assessed predictors of concordance.
Results: 48% of patients had screening documented in the medical record; 98% had a colonoscopy. Concordance for colonoscopy was good (0.84). Education (<high school diploma vs. diploma, OR=0.40, 95% CI 0.21-0.76), insurance source (military service-connected vs. employer, OR=0.19, CI 0.08-0.45; Medicare with or without supplement vs. employer, OR=0.57, CI 0.33-0.98), CRC family history (yes vs. no, OR=0.60, CI 0.39-0.91) and patient duration in office (<1 year vs. 1-25 years, OR=0.22, CI 0.05-0.98) were significant predictors of concordance. As age increased, recent provider visit demonstrated significant (p=0.03) association between place of residence and concordance: at age 55, the small town resident's report was associated with concordance greater than three times that of the metropolitan resident's; at 75, reports of both rural area and large rural residents were associated with concordance at about one-third that of metropolitan residents'.
Conclusion: Concordance between self-reported colonoscopy and evidence in the medical record was good but varied with patient characteristics, healthcare utilization practices and rural-urban residence.
