RESUMO
OBJECTIVES: Patient navigation improves colorectal cancer screening among underserved populations, but limited resources preclude widespread adoption in minority-serving institutions. We evaluated whether a patient's self-selected social contact person can effectively facilitate outpatient screening colonoscopy. METHODS: From September 2014 to March 2017 in an urban tertiary center, 399 black participants scheduled for outpatient screening colonoscopy self-selected a social contact person to be a facilitator and provided the person's phone number. Of these, 201 participants (50.4%) were randomly assigned to the intervention arm for their social contact persons to be engaged by phone. The study was explained to the social contact person with details about colonoscopy screening and bowel preparation process. The social contacts were asked to assist the participants, provide support, and encourage compliance with the procedures. The social contact person was not contacted in the usual care arm, n = 198 (49.6%). We evaluated attendance to the scheduled outpatient colonoscopy and adequacy of bowel preparation. Analysis was performed by intention to treat. RESULTS: The social contact person was reached and agreed to be involved for 130 of the 201 participants (64.7%). No differences were found in the proportion of participants who underwent screening colonoscopy (77.3% vs 77.2%; relative risk = 1.01; 95% confidence interval: 0.91-1.12), but there was a modest increase in the proportion with adequate bowel preparation with social contact involvement (89.1% vs 80.9%; relative risk = 1.10; 95% confidence interval: 1.00-1.21). DISCUSSION: Engaging a patient's social network to serve in the role of a patient navigator did not improve compliance to outpatient screening colonoscopy but modestly improved the adequacy of bowel preparation.

GOALS AND BACKGROUND: The prevalence of Helicobacter pylori infection among patients with peptic ulcer disease has been reported to range from 61 to 94%. Recent studies show a reduction in the prevalence of H. pylori infection in patients with peptic ulcer disease. This study was conducted to determine the prevalence of H. pylori infection in peptic ulcer disease in an inner-city hospital in Washington, DC. METHODS: Medical records of all patients who had undergone upper gastrointestinal endoscopy from July 1997 through June 1999 were reviewed. All patients who had gastric ulcer and/or duodenal ulcer on upper gastrointestinal endoscopy were studied. Demographic characteristics, history of nonsteroidal antiinflammatory drug ingestion, alcohol consumption, and associated diseases were studied. H. pylori was considered to be present if CLOtest and/or histopathology were positive for H. pylori. Patients with negative pathology for H. pylori or negative pathology and CLOtest were considered negative for H. pylori. RESULTS: One-hundred fifty-six patients were found to have gastric and/or duodenal ulcers. Fifty-one ulcer patients did not meet the inclusion criteria and were excluded. Among the 105 patients who were included in the study, gastric ulcers were found in 48 patients (45.7%), duodenal ulcers were found in 46 patients (43.8%), and both gastric and duodenal ulcers were found in 11 patients (10.5%). H. pylori was present in 66.7% of gastric ulcer patients and in 69.5% of duodenal ulcer patients. Antral histology and CLOtest were in agreement 96% of the time. CONCLUSIONS: At the District of Columbia General Hospital, an inner-city hospital serving predominantly an African-American community, the prevalence of H. pylori in ulcer patients compares similarly to other more recent studies that have found a decreased prevalence of this bacterial infection in ulcer patients. This suggests that the treatment of H. pylori in minority patients is reducing the proportion of ulcers due to this bacterium, as has been seen with the majority population.
