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...
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...
IMPORTANCE AND AIMS The role of CT colonography (CTC) as a colorectal cancer (CRC) screening test is uncertain. The aim of our trial was to compare participation and detection rate (DR) with sigmoidoscopy (flexible sigmoidoscopy (FS)) and CTC in a screening setting. DESIGN SETTING AND PARTICIPANTS We conducted two randomised clinical trials (RCTs). (1) Participation RCT: individuals, aged 58 ...
RATIONALE Rates of colorectal cancer (CRC) are on the rise in Canada. Flexible sigmoidoscopy (FS) is an initial screening test for CRC primarily used in adults aged 50 years and older at average risk for the disease. Physicians and registered nurses have been shown to have the same effectiveness in performing a FS procedure. This paper presents an analysis of the use of registered nurses (RN) c...
BACKGROUND Colorectal cancer is the third most frequent cancer in the world. As the sojourn time for this cancer is several years and a good prognosis is associated with early stage diagnosis, screening has been implemented in a number of countries. Both screening with faecal occult blood test and flexible sigmoidoscopy have been shown to reduce mortality from colorectal cancer in randomised co...
OBJECTIVES Clostridium difficile associated diarrhoea (CDAD) is a hospital acquired infection in which optimal methods for diagnosis and the scale of the problem in the community remain to be determined. In hospitalised patients with CDAD, we aimed to (i) study patients in whom the onset of diarrhoea was in the community and (ii) investigate the role of bedside flexible sigmoidoscopy in diagnos...
OBJECTIVE Patients with rectal bleeding are being over investigated because of the fear of missing colorectal cancers. This study aimed to identify the percentage of patients <45 years of age who undergo flexible sigmoidoscopy for rectal bleeding, and to assess and compare the incidence of colorectal cancers and polyps above and below this age. METHODS Patients who underwent flexible sigmoido...
OBJECTIVE To review the diagnostic yield of flexible sigmoidoscopy in patients presenting with bright red rectal bleeding. DESIGN Retrospective study. SETTING University teaching hospital, Hong Kong. SUBJECTS AND METHODS Patients who underwent flexible sigmoidoscopy between January 1995 and April 1996 for investigation of bright red rectal bleeding were recruited. The extent of the endosc...
The most common investigation carried out in UK hospitals to investigate bright red rectal bleeding is a flexible sigmoidoscopy (FS). The role of flexible sigmoidoscopy in colorectal screening has not yet been fully ascertained and colonoscopy remains the investigation of choice for the diagnosis of colonic pathology. However, FS is a simple, quick, sensitive and specific investigation to diagn...
BACKGROUND Flexible sigmoidoscopy is a technical skill that has been successfully performed by suitably trained colorectal nurse practitioners in the USA. However, no recognised training course exists for nurse practitioners in the UK. AIMS To design and evaluate a training programme for nurse endoscopists. METHODS A multidisciplinary committee of nurses and clinicians developed a structure...
