BACKGROUND The purpose of this study was to identify factors associated with colorectal cancer (CRC) screening test preference and examine the association between test preference and test completed. METHODS Patients (n = 1224) were 50-70 years, at average CRC risk, and overdue for screening. Outcome variables were preference for fecal occult blood test (FOBT), colonoscopy (COL), sigmoidoscopy...

OBJECTIVE Colorectal cancer (CRC) screening rates remain lower among some racial/ethnic groups and individuals with low income or educational attainment who are often cared for within community health centers (CHCs). We surveyed clinicians in a network of CHCs to understand their attitudes, practice patterns, and perceived barriers to CRC screening. METHODS A clinician survey was conducted in...

BACKGROUND The use of colonoscopy as a primary screening tool for colorectal cancer is gaining momentum owing to several studies suggesting superior effectiveness and the recent, favorable decision by Medicare to cover all routine screening colonoscopies. This study documents the use of colonoscopy versus other tests to screen for colorectal cancer. MATERIALS AND METHODS Data from the 2000 Na...

BACKGROUND The need to develop valid methods for sampling and analyzing fecal specimens for microbiome studies is increasingly important, especially for large population studies. METHODS Some of the most important attributes of any sampling method are reproducibility, stability, and accuracy. We compared seven fecal sampling methods [no additive, RNAlater, 70% ethanol, EDTA, dry swab, and pre...

The purpose of this study was to compare self-reports of colorectal cancer (CRC) screening by fecal occult blood test (FOBT), sigmoidoscopy, and colonoscopy with medical records in a multiprovider health care setting. Relatives of CRC patients residing in Ontario, Canada completed a questionnaire indicating whether or not they had ever had any CRC screening tests. Medical records from physician...

Objectives: To assess the cost-effectiveness of computed tomography colonography (CTC) for a colorectal cancer screening program in a working population (aged 40–60 years) from a health care payer’s perspective in Japan. Methods: A Markov model for colorectal cancer was constructed to estimate the long-term (10-year, 20-year, and 30year) effect of introducing CTC for three different strategies ...

This study investigated perceived barriers and benefits, as conceptualized by the Health Belief Model,in relation to screening for colorectal cancer (CRC) among African-American adults participating in a church-based health promotion program. CRC is one of the most common cancers and is the second leading cause of cancer death for men and women. Screening can be effective at detecting cancer at...

The primary objective of this study was to determine the prevalence of colorectal cancer (CRC) screening among eligible patients in a large medical practice. A secondary objective was to compare CRC screening rates obtained from medical records with physician self-reported CRC screening recommendation. We conducted a retrospective record review of 214 patients ages > or = 50 years of a large mu...

Valid and reliable self-report measures of cancer screening behaviors are important for evaluating efforts to improve adherence to guidelines. We evaluated test-retest reliability and validity of self-report of the fecal occult blood test (FOBT), sigmoidoscopy (SIG), colonoscopy (COL), and barium enema (BE) using the National Cancer Institute colorectal cancer screening (CRCS) questionnaire. A ...

Modelling A decision model based on a Markov process was used to model the total costs and effectiveness of the three screening strategies. The timeframe of each cycle was one year. The model referred to a hypothetical population of 100,000 persons aged 50 years. If the annual FOBT is negative, patients have to wait for the next annual test and if positive, patients are referred to colonoscopy....
