Perception of Colonoscopy Benefits: A Gap in Patient Knowledge?
ABSTRACT 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.

ABSTRACT: Tobacco smoking is associated with a higher risk of developing colorectal cancer. This study was designed to assess the role of smoking in early onset of colorectal pathology. This was a prospective cross-sectional study of 997 patients with colorectal cancer. Age of colorectal cancer diagnosis was studied in two groups of patients, i.e., smokers (>10 pack-years) and nonsmokers. Confounding factors, such as alcohol drinking, obesity, and gender, also were studied using a correlation analysis and multivariate logistic regression analysis. Of the 997 patients, 852 had sufficient data for analysis and were included. Baseline analysis showed that excluded patients had similar demographic characteristics. Smokers (n=108) reported symptoms related to colorectal cancer at an earlier mean age (64.1 (standard deviation, 11.7) years) than nonsmokers (69.6 (standard deviation, 12.6) years; mean difference, 5.5 (standard deviation, 1.2 years); P<0.001). Impact of smoking according to the bowel segment involved was significant for slow-transit segments (transverse and sigmoid colon and rectum). Multivariate analysis revealed that tobacco smoking was the only independent risk factor of early onset of colorectal cancers. Tobacco smoking could be a factor of early onset of colorectal cancers especially for slow-transit bowel segments. If these findings are confirmed in larger studies, screening for colorectal cancer should not involve a simple sigmoidoscopy but also an exploration of transverse colon in smokers.Diseases of the Colon & Rectum 01/2007; 49(12):1893-6.

ABSTRACT: Primary-care physicians have significant influence on whether or not their patients participate in colorectal cancer screening (CRCS). This study explored the association of physicians' personal health beliefs, medical history, and personal participation in CRCS with their practice patterns regarding CRCS. Perceived personal risk for colorectal cancer (CRC) was associated with compliance with American Cancer Society (ACS) guidelines for CRCS for their patients (P = 0.03). For physicians at low risk for CRC, their perception of the seriousness of CRC was significantly associated with compliance (P = 0.047). For physicians at, at least, average risk for CRC, personal participation in CRCS did not predict whether they recommend CRCS to their patients. Efforts to improve physicians' understanding about their own susceptibility to CRC and the seriousness of CRC may improve their compliance with making recommendations for CRCS to their patients and may improve their participation in CRCS.Digestive Diseases and Sciences 06/2005; 50(5):809-14.
