Our study aimed to determine, for patients who had undergone recent colonoscopy, associations between specific colonoscopy patient characteristics, exam characteristics and patients' perception of colonoscopy reducing their risk of dying from colorectal cancer. A cross-sectional analysis was conducted using data (2004-2008) from the New Hampshire Colonoscopy Registry, consisting of a Self-report Questionnaire, Colonoscopy Report form, and a Follow-up Questionnaire, which measured agreement responses to the statement, "Having a colonoscopy decreased my chances of dying from colon cancer". Chi-square tests and logistic regression were used to assess differences in patient responses by patient and colonoscopy characteristics. A majority of patients (N=5,672, 81%) agreed that having a colonoscopy decreased their chances of dying from colon cancer. Patients with a personal history of polyps were more likely to agree that colonoscopy reduced their chances of dying compared to patients without prior polypectomy [OR (95% CI) =1.34 (1.06, 1.69)] and patients with a family history of colorectal cancer were 33% more likely to agree to the statement than those without a family history [OR (95% CI) =1.33 (1.12, 1.58)]. Personal history of polyps and family history of colorectal cancer are significant predictors of patients' positive perception of colonoscopy, suggesting that personal experience, rather than the potential preventive effect of colonoscopy itself, may influence the perceived benefit of colonoscopy. Intervention efforts should be made to effectively disseminate knowledge of the preventive benefit of colonoscopy.
[Show abstract][Hide abstract] ABSTRACT: Nebraska ranks 36th nationally in colorectal cancer screening. Despite recent increases in CRC screening rates, rural areas in Nebraska have consistently shown lower rates of CRC screening uptake, compared to urban areas. The objective of this study was to investigate reasons for lower CRC screening rates among Nebraska residents, especially among rural residents. We developed a questionnaire based on Health Belief Model (HBM) constructs to identify factors associated with the use of CRC screening. The questionnaire was mailed in 2014 to adults aged 50-75 years in an urban community in the east and a rural community in the west regions of the state. Multiple logistic regression models were created to assess the effects of HBM constructs, rural residence, and demographic factors on CRC screening use. Of the 1200 surveys mailed, 393 were returned (rural n = 200, urban n = 193). Rural respondents were more likely to perceive screening cost as a barrier. Rural residents were also more likely to report that CRC cannot be prevented and it would change their whole life. In multiple regression models, rural residence, perceived embarrassment, and perceived unpleasantness about screening were significantly associated with reduced odds of receiving colonoscopy. Older age (62 years and older), having a personal doctor, and perceived risk of getting CRC were significantly associated with increased odds of receiving colonoscopy. Interventions to increase uptake of colorectal cancer screening in rural residents should be tailored to acknowledge unique perceptions of screening methods and barriers to screening.
