An open access endoscopy system allows for the direct scheduling of endoscopies by non-gastroenterologist physicians without prior gastroenterology consultation. The aim of our study was to examine our practice of open access endoscopy by evaluating the appropriateness of referrals for colonoscopy and to determine whether there were differences depending on the specialty of the referring clinician. The indication for colonoscopy was assessed in 499 consecutive outpatients referred for colonoscopy at University Hospital, Kuala Lumpur over a 12-month period. The American Society of Gastrointestinal Endoscopy (ASGE) guidelines were used to determine the appropriateness of referrals. 80.6% of colonoscopies requested by the gastroenterologist were performed for accepted indications compared to 50.6% of referrals by the primary care physician (p<0.001) and 67.0% of referrals by the surgeon (p=0.006). The rate of colonoscopies generally not indicated was 2.1% for the gastroenterologist, 25.0% for the internist (p=0.002) and 7.5% for the surgeon (p=0.04). The rate of indications not listed in the ASGE guidelines was significantly lower for requests made by gastroenterologists (17.3%) than those requested by primary care physicians (44.2%; p<0.001). Patients who have had prior consultation with the gastroenterologist were significantly more likely to undergo colonoscopy for appropriate indications than among patients who were referred through an open access system. The rate of inappropriate indications for colonoscopy was also significantly lower when the gastroenterologist made the referral. A substantial proportion of colonoscopies (25.4%) was performed for indications not listed in the ASGE guidelines.

Appropriateness of colonoscopy using the ASGE guidelines: experience in a large Asian hospital

Chan TH, Goh KL

PMID: 16412034

The is currently a heavy burden on endoscopy services worldwide and although guidelines for the appropriate use of esophagogastroduodenoscopy (EGD) have been well studied, there are few such studies with respect to colonoscopy and none for the Asia-Pacific region. This study aimed, firstly, to determine the 'appropriateness of colonoscopy' for procedures performed in the endoscopy unit of a large Asian hospital using the American Society of Gastrointestinal Endoscopy (ASGE) 2000 guidelines, and secondly, to determine predictive factors including 'appropriateness of colonoscopy' for positive findings and colorectal cancer (CRC).

Colorectal Cancer Awareness and Screening Preference: A Survey during the Malaysian World Digestive Day Campaign

PMID: 26745083

BACKGROUND: Although the incidence of colorectal cancer in Malaysia is increasing, awareness of this cancer, including its symptoms, risk factors and screening methods, remains low among Malaysian populations. This survey was conducted with the aim of (i) ascertaining the awareness level regarding colorectal cancer symptoms, risk factors and its screening among the general populations and (ii) assessing the public preference and willingness to pay for colorectal cancer screening.
MATERIALS AND METHODS: The questionnaire was distributed in eight major cities in West Malaysia during the World Health Digestive Day (WDHD) campaign. Two thousand four hundred and eight respondents participated in this survey.
RESULTS: Generally, awareness of colorectal cancer was found to be relatively good. Symptoms such as change in bowel habit, blood in the stool, weight loss and abdominal pain were well recognized by 86.6%, 86.9%, 83.4% and 85.6% of the respondents, respectively. However, common risk factors such as positive family history, obesity and old age were acknowledged only by less than 70% of the respondents. Almost 80% of the respondents are willing to take the screening test even without any apparent symptoms. Colonoscopy is the preferred screening method, but only 37.5% were willing to pay from their own pocket to get early colonoscopy.
CONCLUSIONS: Continous cancer education should be promoted with more involvement from healthcare providers in order to make future colorectal cancer screening programs successful.

Fulltext Effect of an intensive patient educational programme on the quality of bowel preparation for colonoscopy: a single-blind randomised controlled trial

OBJECTIVE: Preprocedural bowel preparation is necessary for optimal colonoscopy visualisation. However, it is challenging to achieve high-quality bowel preparation among patients scheduled for colonoscopy. This study aims to evaluate the impact of an intensive patient educational programme on the quality of bowel preparation.
DESIGN: An accessor-blinded randomised controlled trial was carried out at the outpatient surgical clinic of a tertiary hospital. Patients were randomly assigned to the control group (received standard written and verbal instructions) or the experimental group (received an intensive and structured educational programme). All subjects completed a questionnaire before colonoscopy to assess their compliance, acceptability, and tolerability towards bowel preparation regime. Quality of bowel preparation was determined using the Boston Bowel Preparation Scale (BBPS).
RESULTS: A total of 300 subjects who fulfilled the inclusion criteria were recruited. The experimental group had a significantly higher proportion of good quality bowel preparation than the control group (98.7% vs 52.3%, p<0.001). The median total BBPS score was also significantly higher in the experimental group (8 vs 5, p<0.001). Factors associated with good quality of bowel preparation included educational programme (OR: 22.79, 95% CI: 4.23 to 122.85, p<0.001), compliance to bowel cleansing agent (OR: 24.98, 95% CI 3.12 to 199.71, p<0.001), very difficult acceptability of preparation (OR: 0.11, 95% CI 0.03 to 0.38, p<0.001), tolerability towards bowel preparation (OR: 4.98, 95% CI 1.44 to 17.20, p<0.011) and hypomotility drugs (OR: 3.03, 95% CI 0.12 to 0.91, p<0.05).
CONCLUSION: An intensive patient educational programme can significantly improve the quality of bowel preparation for colonoscopy.
