To determine patient acceptability of barium enema (BE) or CT colonography (CTC). After ethical approval, 921 consenting patients with symptoms suggestive of colorectal cancer who had been randomly assigned and completed either BE (N = 606) or CTC (N = 315) received a questionnaire to assess experience of the clinical episode including bowel preparation,(More)
OBJECTIVES CT colonography (CTC) may be an acceptable test for colorectal cancer screening but bowel preparation can be a barrier to uptake. This study tested the hypothesis that prospective screening invitees would prefer full-laxative preparation with higher sensitivity and specificity for polyps, despite greater burden, over less burdensome(More)
OBJECTIVES To examine public perceptions of and preferences for colonoscopy vs. CT colonography (CTC) as technologies for colorectal cancer (CRC) screening. METHODS Six discussion groups were carried out with 30 adults aged 49-60 years (60% female). Information about different aspects of the tests (e.g. sensitivity, practical issues) was presented(More)
PURPOSE To establish the relative weighting given by patients and healthcare professionals to gains in diagnostic sensitivity versus loss of specificity when using CT colonography (CTC) for colorectal cancer screening. MATERIALS AND METHODS Following ethical approval and informed consent, 75 patients and 50 healthcare professionals undertook a discrete(More)
AIMS To explore the relative value patients place on comfort and convenience versus test sensitivity and specificity in the context of computed tomographic colonography (CTC) screening. MATERIALS AND METHODS Twenty semi-structured interviews were carried out with patients attending hospital for radiological tests unrelated to CTC. Preferences for CTC with(More)
PURPOSE To use a randomized design to compare patients' short- and longer-term experiences after computed tomographic (CT) colonography or colonoscopy. MATERIALS AND METHODS After ethical approval, the trial was registered. Patients gave written informed consent. Five hundred forty-seven patients with symptoms suggestive of colorectal cancer who had been(More)
Background Screening participants with abnormal faecal occult blood test results who do not attend further testing are at high risk of colorectal cancer, yet little is known about their reasons for non-attendance. Methods We conducted a medical record review of 170 patients from two English Bowel Cancer Screening Programme centres who had abnormal guaiac(More)
PURPOSE To determine the maximum rate of false-positive diagnoses that patients and health care professionals were willing to accept in exchange for detection of extracolonic malignancy by using computed tomographic (CT) colonography for colorectal cancer screening. MATERIALS AND METHODS After obtaining ethical approval and informed consent, 52 patients(More)
A wide range of screening technologies is available for colorectal cancer screening. There is demand to discover public preferences for these tests on the rationale that tailoring screening to preferences may improve uptake. This review describes a type of study (conjoint analysis) used to assess people's preferences for colorectal cancer screening tests(More)
There is general agreement among public health practitioners, academics, and policymakers that people offered health screening tests should be able to make informed choices about whether to accept. Robust measures are necessary in order to gauge the extent to which informed choice is achieved in practice and whether efforts to improve it have succeeded.(More)
