Effect of Functional Status on the Quality of Bowel Preparation in Elderly Patients Undergoing Screening and Surveillance Colonoscopy

BACKGROUND/AIMS: Optimal bowel preparation is essential for successful screening or for surveillance colonoscopy (SC). Inadequate bowel preparation is associated with older age, the male gender, and the presence of certain comorbidities. However, the association between patients' functional status and bowel preparation quality has not been studied. We prospectively examined the relationship between functional status, namely, the ability to perform activities of daily living (ADLs) and ambulate, and the quality of bowel preparation in elderly patients undergoing SC. METHODS: Before undergoing SC, 88 elderly patients were surveyed regarding their functional status, specifically regarding their ability to perform ADLs and ambulate a quarter of a mile. Gastroenterologists then determined the quality of the bowel preparation, which was classified as either adequate or inadequate. Then, the frequency of inadequate bowel preparation in patients who did or did not experience difficulty performing ADLs and ambulating was calculated. RESULTS: Difficulty ambulating (unadjusted odds ratio [OR], 4.83; p<0.001), difficulty performing ADLs (OR, 2.93; p=0.001), and history of diabetes (OR, 2.88; p=0.007) were significant univariate predictors of inadequate bowel preparation. After adjusting for the above variables, only difficulty ambulating (adjusted OR, 5.78; p=0.004) was an independent predictor of inadequate bowel preparation. CONCLUSIONS: Difficulty with ambulation is a strong predictor of inadequate bowel preparation in elderly patients undergoing SC.

Screening Colonoscopy among Uninsured and Underinsured Urban Minorities

BACKGROUND/AIMS: Uninsured individuals have lower rates of screening colonoscopy (SC), and little is known regarding the pathology results obtained when they undergo colonoscopies. Since 2004, we have participated in a program that offers SC to uninsured New Yorkers; herein, we report our findings. METHODS: Uninsured, average-risk patients who were at least 50 years of age underwent SC at our institution between April 2004 and June 2011. We analyzed polyp pathology, location, size, incidence of adenomas, and incidence of adenomas with advanced pathology (AAP) with respect to ethnicity, gender, and age. RESULTS: Out of 493 referrals, 222 patients completed the colonoscopies. Polyps were identified in 21.2% of all patients; 14% had adenomas, and 4.5% had AAP. The rates of adenomas among African-Americans, Hispanics, and Whites were 24.3%, 12.1%, and 11.6%, respectively, and the corresponding rates of AAP were 10.8%, 3.5%, and 2.3%. Differences in the polyp type, location, and AAP did not reach statistical significance with respect to ethnicity or gender. Patients aged 60 and older were found to have a higher rate of advanced adenomas compared with younger patients (8.6% vs 2.6%, p=0.047). CONCLUSIONS: Further efforts to fund screening colonoscopies for uninsured individuals will likely result in the identification of advanced lesions of the colon before they progress to colorectal cancer.
