We compared health services use, surgical rate, and specialist gastroenterologist care in rural and urban inflammatory bowel disease (IBD) patients in Canada.Methods: We used validated algorithms that were applied to population-based health administrative data to identify all people living with the following three Canadian provinces: Alberta, Manitoba, and Ontario (ON). We compared rural residents with urban residents for time to diagnosis, hospitalizations, outpatient visits, emergency department (ED) use, surgical rate, and gastroenterologist care. Multivariable regression compared the outcomes in rural/urban patients, controlling for confounders. Provincial results were meta-analyzed using random-effects models to produce overall estimates.Results: A total of 36,656 urban and 5,223 rural residents with incident IBD were included. Outpatient physician visit rate was similar in rural and urban patients. IBD-specific and IBD-related hospitalization rates were higher in rural patients (incidence rate ratio [IRR] 1.17, 95% CI 1.02–1.34, and IRR 1.27, 95% CI 1.04–1.56, respectively). The rate of ED visits in ON were similarly elevated for rural patients (IRR 1.53, 95% CI 1.42–1.65, and IRR 1.33, 95% CI 1.25–1.40). There were no differences in surgical rates or prediagnosis lag time between rural and urban patients. Rural patients had fewer IBD-specific gastroenterologist visits (IRR 0.79, 95% CI 0.73–0.84) and a smaller proportion of their IBD-specific care was provided by gastroenterologists (28.3% vs 55.2%, P65 years (33.0% vs 59.2%, P

Few studies have examined exercise placement within children-specific programming. This study aimed to investigate the frequency and type of exercise placement in children-specific television broadcasts and to compare placements on the UK and Irish television channels.Methods: Content analysis for five weekdays’ worth of children-specific television broadcasting totaling 82.5 hours on both the UK (British Broadcasting Corporation) and Irish (Radió Teilifís Éireann) television channels was performed. For the purposes of comparing the UK and Irish placements, analysis was restricted to programming broadcast between 6 am and 11.30 am. Exercise placements were coded based on type of activity, activity context, activity motivating factors and outcome, and characters involved.Results: A total of 780 cues were recorded during the total recording period. A wide variety of sports were depicted, but dancing-related cues were most commonly seen (n=163, 23.3%), with the majority of cues being of mild (n=365, 65.9%) or moderate (n=172, 31.0%) intensity. The majority of cues were associated with a positive outcome (n=404, 61.4%), and social motivations were most commonly seen (n=289, 30.3%). The Irish and the UK portrayals were broadly similar.Conclusion: This study highlights the wide variety of sports portrayed and the active effort undertaken by television stations to depict physical exercise and recreation in a positive light.

Abstract Background Overweight and obesity is a growing problem in Ireland. Many parents are unaware when their child is overweight or obese. Our objectives were to examine parents’ perceptions of a healthy diet and their children’s BMI; and to evaluate the food offered to children in our paediatric in-patient unit. Findings A retrospective questionnaire was distributed to 95 patients and their families admitted over one month. Seventy-eight had BMI values calculated (42 males, 36 females). Twenty-one children (26.9%) were overweight/obese: 14/21 parents (66.7%) thought their child had a normal weight. Sixty percent of children served dinner in the hospital were given fried potatoes. Four had fruit/vegetables. Forty-six parents brought food into hospital, of these 14 brought purchased food. Conclusions This study highlights the problem of child obesity in Ireland and parental underestimation of this problem. The nutritional value of food served to children in hospital needs to be improved and hospital admissions used as opportunities to promote healthy eating habits.

Background and Aims: Since the onset of the Coronavirus disease 2019 (COVID-19) pandemic, there has been a significant opportunity to leverage virtual platforms for communication and dissemination of knowledge. An online survey was conducted to examine the viewpoints of World Gastroenterology Organization (WGO) leaders concerning the necessity, primary priority areas, and implementation strategies for a virtual global gastroenterology educational program., Methods: We conducted a survey of leaders of WGO member societies to assess their opinions on creating opportunities for global education using virtual platforms, identifying practical implementation steps and priority educational areas., Results: Responses were obtained from 57/117 (48.7%) contacted leaders with 56/57 (98.2%) identifying such a need. Five mutually exclusive priority educational topics were proposed in the survey: clinical gastroenterology, endoscopy, nutritional support, research methodology, and professional development. Overall, most participants prioritized clinical gastroenterology (45/57; 78.9%) and endoscopy/hand skills (27/57; 47.3%) as educational topics to be addressed by the virtual global gastroenterology educational program. A majority of WGO member society leaders surveyed favored monthly teaching activities (33/57; 57.8%), ideally carried out between 1500-2100 local time (31/57; 54.3%), ideally with no administrative fees (47/57; 82.4%)., Conclusions: This truly global survey of WGO member societies achieved a good response rate and provides important insights into the need for and scope of future virtual education programs under the aegis of the WGO.

The environment is changing rapidly under pressure from 3 related drivers: climate change, pollution, and biodiversity loss. These environmental changes are affecting digestive health and disease in multiple ways. Heat extremes can cause intestinal and hepatic dysfunction. Access to adequate amounts of food of high nutritional content and to clean water is under threat. Extreme weather is associated with flooding and enteric infections and affects the delivery of care through infrastructure loss. Air, water, and soil pollution from chemicals and plastics are emerging as risk factors for a variety of intestinal diseases including eosinophilic esophagitis, metabolic dysfunction associated fatty liver disease, digestive tract cancers, inflammatory bowel disease, and functional bowel disease. Migration of populations to cities and between countries poses a special challenge to the delivery of digestive care. The response to the threat of environmental change is well underway in the global digestive health community, especially with regard to understanding and reducing the environmental impact of endoscopy. Individuals, and peer societies, are becoming more engaged, and have an important role to play in meeting the challenge., (© 2024 The Authors.)

Background and study aims Adequacy of endoscope disinfection in resource-limited settings is unknown. Adenosine triphosphate (ATP) testing is useful for evaluation of endoscope reprocessing, and ATP <200 relative light units (RLUs) after manual endoscope cleaning has been associated with adequacy of endoscope disinfection. Methods Consecutive endoscopes undergoing reprocessing at five World Gastroenterology Organisation (WGO) training centers underwent ATP testing before and after an on-site educational intervention designed to optimize reprocessing practices. Results A total of 343 reprocessing cycles of 65 endoscopes were studied. Mean endoscope age was 5.3 years (range 1-13 years). Educational interventions, based on direct observation of endoscope reprocessing practices at each site, included refinements in pre-cleaning, manual cleaning, high-level disinfection, and endoscope drying and storage. The percentage of reprocessing cycles with post-manual cleaning ATP ≧200 decreased from 21.4% prior to educational intervention to 14.8% post-intervention ( P =0.11). In multivariable logistic modelling, gastroscopes were significantly less likely (odds ratio [OR] 0.04, 95% confidence interval [CI] 0.01-0.19; P <0.001) than colonoscopes to achieve post-manual cleaning ATP < 200. No other factor (educational intervention, study site, endoscope age) was significantly associated with improved outcomes. Endoscope ID was not significantly associated with ATP values, and sites that performed manual versus automated HLD did not have significantly different likelihood of post-manual cleaning ATP <200 (OR 1.18, 95% CI 0.56-2.50; P =0.67). Conclusions In resource-limited settings, approximately 20% of endoscope reprocessing cycles may result in inadequate disinfection. This was not significantly improved by a comprehensive educational intervention. Alternative approaches to endoscope reprocessing are needed., Competing Interests: Conflict of Interest The authors declare that they have no conflict of interest., (The Author(s).

Global warming and climate change are important worldwide issues which are a major human health threat. Climate change can affect the gastrointestinal (GI) system in many ways. Increased rainfall events and flooding may be associated with increased GI infections and hepatitis. Climate change could cause changes in gut microbiota, which may impact the pattern of GI diseases. The stress of access to essential needs such as clean water and food, the effects of forced migration, and natural disasters could increase brain-gut axis disorders. The association between air pollution and GI disorders is another challenging issue. There is a lot to do personally and professionally as gastroenterologists regarding climate change., Competing Interests: Competing Interests The authors declare no conflict of interest related to this work., (© 2023 Middle East Journal of Digestive Diseases.)

Objectives: We estimated and compared the travel related carbon emissions of the annual meeting of the Canadian Association of Gastroenterology between the two most common geographical locations of the meeting., Methods: We modelled the car, train and flight travel journey of each registrant to two annual meetings. One was held in Toronto, close to where the majority of Gastroenterogists live, the other in Banff in the west of the country. We used validated carbon emission outputs per kilometer of travel., Results: The average per capita distance travelled to the Toronto meeting was 2845 km, resulting in 0.540 tonnes (t) of CO 2 equivalent (CO 2 e) emitted per person. When the meeting was held in Banff emissions were 41% higher than those in Toronto with an average distance travelled of 3949 km and 0.760t of CO 2 e emitted per person. Almost all of the travel related carbon emissions for both meetings were generated by flying., Conclusions: Even when held close to the largest population centre, there is a large environmental impact from travel to annual meetings. Importantly, choice of meeting location has a very big impact on difference in carbon emissions. Societies need to consider the site of meetings and reduce the number of in-person attendees if they wish to reduce their carbon footprint. Hybrid models participants should be considered. Our analysis also suggests, other medical societies who wish to model their annual meetings can use a simplified model, using flying distance only, to estimate travel-related emissions., (© The Author(s) 2021.

Background: It is necessary for health planners, educators and physician and patient organizations to be aware of trends in gastroenterologist (GI) numbers in order to ensure that patients have timely access to care., Methods: The number of GIs in practice and the number of trainees in the specialty was determined for 2018 using three national databases compared with previous years., Results: In 2018, there were 787 GIs in Canada, which equated to 2.1 GIs per 100,000 population. There are marked differences between provinces with numbers ranging from 1.1 to 2.9 per 100,000. There are 53 GIs specializing in pediatric GI care. Forty-six per cent of practitioners under the age of 35 years are female. Seventy-two residents are training in adult GI and six in pediatrics. Approximately 75% of fellows in adult and pediatric GI are training on temporary visas. The number of adult GIs is decreasing despite increasing national population growth and service demand. The numbers of trainees in both adult and pediatric GI are lower than in 2010. If these trends continue, wait times for GI care, which are already poor, will likely increase further., Conclusions: Continued monitoring of human resource numbers, patient access to care and validation of current data is required.The purpose of this report is to present the number of gastroenterologists (GIs), both in practice and in training, in Canada for 2018. We also wished to examine the 2018 numbers by province and gender, compare the 2018 numbers with those of previous years and describe the practice settings and organization., (© The Author(s) 2020.

Objective: To review and summarize the recently developed Canadian Association of Gastroenterology screening recommendations for patients with a family history of colorectal cancer (CRC) or adenoma from a family medicine perspective., Quality of Evidence: A systematic review and meta-analysis was performed to synthesize knowledge regarding family history and CRC. The Cochrane Central Register of Controlled Trials, MEDLINE, and EMBASE were searched with the following MeSH terms: colorectal cancers or neoplasms, screen or screening or surveillance, and family or family history. Known hereditary syndromes were excluded. The Grading of Recommendations Assessment, Development and Evaluation methodology was used to establish certainty in reviewed evidence. Most recommendations are conditional recommendations with very low-quality evidence., Main Message: Individuals who have 1 first-degree relative (FDR) with CRC or an advanced adenoma diagnosed at any age are recommended to undergo colonoscopy every 5 to 10 years starting at age 40 to 50 years or 10 years younger than the age at diagnosis of the FDR, although fecal immunochemical testing at an interval of every 1 to 2 years can be used. Individuals with FDRs with non-advanced adenomas or a history of CRC in second-degree relatives should be screened according to average-risk guidelines. Lifestyle modification can statistically significantly decrease risk of CRC and should be considered in all patients., Conclusion: These guidelines acknowledge the many factors that can increase an individual's risk of developing CRC and allow for judgment to be employed depending on the clinical scenario. Lifestyle advice already given to patients for weight, blood pressure, and heart disease management will reduce the risk of CRC if implemented, and this combined with more targeted screening for higher-risk individuals will hopefully be successful in decreasing CRC mortality in Canada., (Copyright© the College of Family Physicians of Canada.)

Background & Aims: Inflammatory bowel diseases (IBDs) exist worldwide, with high prevalence in North America. IBD is complex and costly, and its increasing prevalence places a greater stress on health care systems. We aimed to determine the past current, and future prevalences of IBD in Canada., Methods: We performed a retrospective cohort study using population-based health administrative data from Alberta (2002-2015), British Columbia (1997-2014), Manitoba (1990-2013), Nova Scotia (1996-2009), Ontario (1999-2014), Quebec (2001-2008), and Saskatchewan (1998-2016). Autoregressive integrated moving average regression was applied, and prevalence, with 95% prediction intervals (PIs), was forecasted to 2030. Average annual percentage change, with 95% confidence intervals, was assessed with log binomial regression., Results: In 2018, the prevalence of IBD in Canada was estimated at 725 per 100,000 (95% PI 716-735) and annual average percent change was estimated at 2.86% (95% confidence interval 2.80%-2.92%). The prevalence in 2030 was forecasted to be 981 per 100,000 (95% PI 963-999): 159 per 100,000 (95% PI 133-185) in children, 1118 per 100,000 (95% PI 1069-1168) in adults, and 1370 per 100,000 (95% PI 1312-1429) in the elderly. In 2018, 267,983 Canadians (95% PI 264,579-271,387) were estimated to be living with IBD, which was forecasted to increase to 402,853 (95% PI 395,466-410,240) by 2030., Conclusion: Forecasting prevalence will allow health policy makers to develop policy that is necessary to address the challenges faced by health systems in providing high-quality and cost-effective care., (Copyright © 2019 AGA Institute.

Background & Aims: A family history (FH) of colorectal cancer (CRC) increases the risk of developing CRC. These consensus recommendations developed by the Canadian Association of Gastroenterology and endorsed by the American Gastroenterological Association, aim to provide guidance on screening these high-risk individuals., Methods: Multiple parallel systematic review streams, informed by 10 literature searches, assembled evidence on 5 principal questions around the effect of an FH of CRC or adenomas on the risk of CRC, the age to initiate screening, and the optimal tests and testing intervals. The GRADE (Grading of Recommendation Assessment, Development and Evaluation) approach was used to develop the recommendations., Results: Based on the evidence, the Consensus Group was able to strongly recommend CRC screening for all individuals with an FH of CRC or documented adenoma. However, because most of the evidence was very-low quality, the majority of the remaining statements were conditional ("we suggest"). Colonoscopy is suggested (recommended in individuals with ≥2 first-degree relatives [FDRs]), with fecal immunochemical test as an alternative. The elevated risk associated with an FH of ≥1 FDRs with CRC or documented advanced adenoma suggests initiating screening at a younger age (eg, 40-50 years or 10 years younger than age of diagnosis of FDR). In addition, a shorter interval of every 5 years between screening tests was suggested for individuals with ≥2 FDRs, and every 5-10 years for those with FH of 1 FDR with CRC or documented advanced adenoma compared to average-risk individuals. Choosing screening parameters for an individual patient should consider the age of the affected FDR and local resources. It is suggested that individuals with an FH of ≥1 second-degree relatives only, or of nonadvanced adenoma or polyp of unknown histology, be screened according to average-risk guidelines., Conclusions: The increased risk of CRC associated with an FH of CRC or advanced adenoma warrants more intense screening for CRC. Well-designed prospective studies are needed in order to make definitive evidence-based recommendations about the age to commence screening and appropriate interval between screening tests., (Copyright © 2018 AGA Institute.

Background & Aims: Although the incidence of inflammatory bowel diseases (IBDs) varies with age, few studies have examined variations between the sexes. We therefore used population data from established cohorts to analyze sex differences in IBD incidence according to age at diagnosis., Methods: We identified population-based cohorts of patients with IBD for which incidence and age data were available (17 distinct cohorts from 16 regions of Europe, North America, Australia, and New Zealand). We collected data through December 2016 on 95,605 incident cases of Crohn's disease (CD) (42,831 male and 52,774 female) and 112,004 incident cases of ulcerative colitis (UC) (61,672 male and 50,332 female). We pooled incidence rate ratios of CD and UC for the combined cohort and compared differences according to sex using random effects meta-analysis., Results: Female patients had a lower risk of CD during childhood, until the age range of 10-14 years (incidence rate ratio, 0.70; 95% CI, 0.53-0.93), but they had a higher risk of CD thereafter, which was statistically significant for the age groups of 25-29 years and older than 35 years. The incidence of UC did not differ significantly for female vs male patients (except for the age group of 5-9 years) until age 45 years; thereafter, men had a significantly higher incidence of ulcerative colitis than women., Conclusions: In a pooled analysis of population-based studies, we found age at IBD onset to vary with sex. Further studies are needed to investigate mechanisms of sex differences in IBD incidence., (Copyright © 2018 AGA Institute. Published by Elsevier Inc. All rights reserved.)

Summary: Dalhousie University, with the help of the other Maritime universities formed and sent a hospital to Europe during the First World War (WWI). They served from January 1916 to April 1919. There is no comprehensive account of the treatment of German wounded by Canadian Medical Services in WWI; however, there is direct photographic and written evidence from the No. 7 Canadian Stationary Hospital that the relationship was one of mutual trust, more characteristic of that between a health care provider and patient than between combatants. The activities of the No. 7 in treating German wounded from the Western Front provide insight into this undocumented aspect of the medical services in WWI. A previously unrecognized painting by Sir William Orpen, one of the leading artists of the 20th century, of the unit at work in France is described. An appendix to this commentary is available at canjsurg.ca.

Background: Levels of endoscopic demand and capacity in West Africa are unclear., Objectives: This paper aims to: 1. describe the current labor and endoscopic capacity, 2. quantify the impact of a mixed-methods endoscopy course on healthcare professionals in West Africa, and 3. quantify the types of diagnoses encountered., Methods: In a three-day course, healthcare professionals were surveyed on endoscopic resources and capacity and were taught through active observation of live cases, case discussion, simulator experience and didactics. Before and after didactics, multiple-choice exams as well as questionnaires were administered to assess for course efficacy. Also, a case series of 23 patients needing upper GI endoscopy was done., Results: In surveying physicians, less than half had resources to perform an EGD and none could perform an ERCP, while waiting time for emergency endoscopy in urban populations was at least one day. In assessing improvement in medical knowledge among participants after didactics, objective data paired with subjective responses was more useful than either alone. Of 23 patients who received endoscopy, 7 required endoscopic intervention with 6 having gastric or esophageal varices. Currently the endoscopic capacity in West Africa is not sufficient. A formal GI course with simulation and didactics improves gastrointestinal knowledge amongst participants.

Objective: The link between childhood obesity and both television viewing and television advertising have previously been examined. We sought to investigate the frequency and type of food and beverage placements in children-specific television broadcasts and, in particular, differences between programme genres., Method: Content of five weekdays of children-specific television broadcasting on both UK (BBC) and Irish (RTE) television channels was summarized. Food and beverage placements were coded based on type of product, product placement, product use and characters involved. A comparison was made between different programme genres: animated, cartoon, child-specific, film, quiz, tween and young persons' programming., Results: A total of 1155 (BBC=450; RTE=705) cues were recorded giving a cue every 4·2 min, an average of 12·3 s/cue. The genre with most cues recorded was cartoon programming (30·8%). For the majority of genres, cues related to sweet snacks (range 1·8-23·3%) and sweets/candy (range 3·6-25·8%) featured highly. Fast-food (18·0%) and sugar-sweetened beverage (42·3%) cues were observed in a high proportion of tween programming. Celebratory/social motivation factors (range 10-40 %) were most common across all genres while there were low proportions of cues based on reward, punishment or health-related motivating factors., Conclusions: The study provides evidence for the prominence of energy-dense/nutrient-poor foods and beverages in children's programming. Of particular interest is the high prevalence of fast-food and sugar-sweetened beverage cues associated with tween programming. These results further emphasize the need for programme makers to provide a healthier image of foods and beverages in children's television.

Background & Aims: Probiotic formulations of single species of bacteria have not been effective in preventing the recurrence of Crohn's disease after surgery. We investigated the ability of VSL#3, a mixture of 8 different bacterial probiotic species, to prevent Crohn's disease recurrence after surgery in a multicenter, randomized, double-blind, placebo-controlled trial., Methods: Within 30 days of ileocolonic resection and re-anastomosis, patients with Crohn's disease were randomly assigned to groups given 1 sachet of VSL#3 (900 billion viable bacteria, comprising 4 strains of Lactobacillus, 3 strains of Bifidobacterium, and 1 strain of Streptococcus salivarius subspecies thermophilus) (n = 59) or matching placebo (n = 60). Colonoscopy was performed at days 90 and 365 to evaluate the neoterminal ileum for disease recurrence and obtain mucosal biopsies for cytokine analysis. Patients from both groups with either no or mild endoscopic recurrence at day 90 received VSL#3 until day 365. The primary outcome was the proportion of patients with severe endoscopic recurrence at day 90., Results: At day 90, the proportion of patients with severe endoscopic lesions did not differ significantly between VSL#3 (9.3%) and placebo (15.7%, P = .19). The proportions of patients with non-severe lesions at day 90 who had severe endoscopic recurrence at day 365 were 10.0% in the early VSL#3 group (given VSL#3 for the entire 365 days) and 26.7% in the late VSL#3 group (given VSL#3 from days 90 through 365) (P = .09). Aggregate rates of severe recurrence (on days 90 and 365) were not statistically different, 20.5% of subjects in the early VSL#3 group and 42.1% in the late VSL#3 group. Patients receiving VSL#3 had reduced mucosal inflammatory cytokine levels compared with placebo at day 90 (P < .05). Crohn's disease activity index and inflammatory bowel disease quality of life scores were similar in the 2 groups., Conclusions: There were no statistical differences in endoscopic recurrence rates at day 90 between patients who received VSL#3 and patients who received placebo. Lower mucosal levels of inflammatory cytokines and a lower rate of recurrence among patients who received early VSL#3 (for the entire 365 days) indicate that this probiotic should be further investigated for prevention of Crohn's disease recurrence.

Background: Nova Scotia has one of the highest incidences of inflammatory bowel disease (IBD) in the world. We wished to determine trends of IBD over time., Methods: All Provincial residents have government provided health insurance and all interactions with the hospital, and physician billing systems, are captured on an administrative database. We used a validated measure to define incident cases of Crohn's (CD), ulcerative colitis (UC) and undifferentiated IBD (IBDU). Incidence rates of these diseases for the years 1996-2009 were calculated., Results: Over the study period, 7,153 new cases of IBD were observed of which 3,046 cases were categorized as CD (42.6%), 2,960 as UC (41.4%) and 1,147 as IBDU (16.0%). Annual age standardized incidence rates were very high but have declined for CD from 27.4 to 17.7/100,000 population and for UC from 21.4 to 16.7/100,000. The decline was seen in all age groups and both genders. The decrease was not explained by a small increase in IBDU., Conclusion: The incidence of CD and UC are decreasing in Nova Scotia. If replicated elsewhere this indicates a reversal after a long period of increasing occurrence of IBD. This has implications for both epidemiology and health planning.

Background: Differences between American (United States [US]) and European guidelines for colonoscopy surveillance may create confusion for the practicing clinician. Under- or overutilization of surveillance colonoscopy can impact patient care., Methods: The Canadian Association of Gastroenterology (CAG) convened a working group (CAG-WG) to review available guidelines and provide unified guidance to Canadian clinicians regarding appropriate follow-up for colorectal cancer (CRC) surveillance after index colonoscopy. A literature search was conducted for relevant data that postdated the published guidelines., Results: The CAG-WG chose the 2012 US Multi-Society Task Force (MSTF) on Colorectal Cancer to serve as the basis for the Canadian position, primarily because the US approach was the simplest and comprehensively addressed the issue of serrated polyps. Aspects of other guidelines were incorporated where relevant. The CAG-WG recommendations differed from the US MSTF guidelines in three main areas: patients with negative index colonoscopy should be followed-up at 10 years using any of the appropriate screening tests, including colonoscopy, for average-risk individuals; among patients with >10 adenomas, a one-year interval for subsequent colonoscopy is recommended; and for long-term follow-up, patients with low-risk adenomas on both the index and first follow-up procedures can undergo second follow-up colonoscopy at an interval of five to 10 years., Discussion: The CAG-WG adapted the US MSTF guidelines for colonoscopy surveillance to the Canadian health care environment with a few modifications. It is anticipated that the present article will provide unified guidance that will enhance physician acceptance and encourage appropriate utilization of recommended surveillance intervals.

Background: Periodically surveying wait times for specialist health services in Canada captures current data and enables comparisons with previous surveys to identify changes over time., Methods: During one week in April 2012, Canadian gastroenterologists were asked to complete a questionnaire (online or by fax) recording demographics, reason for referral, and dates of referral and specialist visits for at least 10 consecutive new patients (five consultations and five procedures) who had not been seen previously for the same indication. Wait times were determined for 18 indications and compared with those from similar surveys conducted in 2008 and 2005., Results: Data regarding adult patients were provided by 173 gastroenterologists for 1374 consultations, 540 procedures and 293 same-day consultations and procedures. Nationally, the median wait times were 92 days (95% CI 85 days to 100 days) from referral to consultation, 55 days (95% CI 50 days to 61 days) from consultation to procedure and 155 days (95% CI 142 days to 175 days) (total) from referral to procedure. Overall, wait times were longer in 2012 than in 2005 (P<0.05); the wait time to same-day consultation and procedure was shorter in 2012 than in 2008 (78 days versus 101 days; P<0.05), but continued to be longer than in 2005 (P<0.05). The total wait time remained longest for screening colonoscopy, increasing from 201 days in 2008 to 279 days in 2012 (P<0.05)., Discussion: Wait times for gastroenterology services continue to exceed recommended targets, remain unchanged since 2008 and exceed wait times reported in 2005.

Background & Aims: Patients use the Internet as a resource for information about their diseases. A systematic review evaluating the quality of information available for inflammatory bowel disease patients on the Internet regarding treatment options was performed., Methods: Google was used to identify 50 websites on 3 occasions. A data quality score (DQS) (potential score, 0-76) was developed to evaluate the content of websites that scores patient information on indications, efficacy, and side effects of treatment. Other outcome measures were a 5-point global quality score, a drug category quality score, the DISCERN instrument, a reading grade level score, and information about integrity., Results: The median DQS was 22, range 0-74, median global quality score was 2.0, and median Flesch-Kincaid reading grade level was 12.0, range 6.9-13.7. Eight websites achieved a global quality score of 4 or 5. The DQS was highly associated with the global quality score (r = 0.82) and the DISCERN instrument (r = 0.89). There was poor association between the DQS and the rank order in all 3 Google searches. Information on funding source (59%) and date of last update (74%) were often lacking., Conclusions: There is marked variation in the quality of available patient information on websites about the treatment options for Crohn's disease and ulcerative colitis. Few websites provided high quality information. There is a need for high quality accredited websites that provide patient-oriented information on treatment options, and these sites need to be updated regularly., (Copyright 2010 AGA Institute.

Long wait times for health care have become a significant issue in Canada. As part of the Canadian Association of Gastroenterology's Human Resource initiative, a questionnaire was developed to survey patients regarding wait times for initial gastroenterology consultation and its impact. A total of 916 patients in six cities from across Canada completed the questionnaire at the time of initial consultation. Self-reported wait times varied widely, with 26.8% of respondents reporting waiting less than two weeks, 52.4% less than one month, 77.1% less than three months, 12.5% reported waiting longer than six months and 3.6% longer than one year. One-third of patients believed their wait time was too long, with 9% rating their wait time as 'far too long'; 96.4% believed that maximal wait time should be less than three months, 78.9% believed it should be less than one month and 40.3% believed it should be less than two weeks. Of those working or attending school, 22.6% reported missing at least one day of work or school because of their symptoms in the month before their appointment, and 9.0% reported missing five or more days in the preceding month. A total of 20.2% of respondents reported being very worried about having a serious disease (ie, scored 6 or higher on 7-point Likert scale), and 17.6% and 14.8%, respectively, reported that their symptoms caused major impairment of social functioning and with the activities of daily living. These data suggest that a significant proportion of Canadians with digestive problems are not satisfied with their wait time for gastroenterology consultation. Furthermore, while awaiting consultation, many patients experience an impaired quality of life because of their gastrointestinal symptoms.

Background: Assessment of current wait times for specialist health services in Canada is a key method that can assist government and health care providers to plan wisely for future health needs. These data are not readily available. A method to capture wait time data at the time of consultation or procedure has been developed, which should be applicable to other specialist groups and also allows for assessment of wait time trends over intervals of years., Methods: In November 2008, gastroenterologists across Canada were asked to complete a questionnaire (online or by fax) that included personal demographics and data from one week on at least five consecutive new consultations and five consecutive procedure patients who had not previously undergone a procedure for the same indication. Wait times were collected for 18 primary indications and results were then compared with similar survey data collected in 2005., Results: The longest wait times observed were for screening colonoscopy (201 days) and surveillance of previous colon cancer or polyps (272 days). The shortest wait times were for cancer-likely based on imaging or physical examination (82 days), severe or rapidly progressing dysphagia or odynophagia (83 days), documented iron deficiency anemia (90 days) and dyspepsia with alarm symptoms (99 days). Compared with 2005 data, total wait times in 2008 were lengthened overall (127 days versus 155 days; P<0.05) and for most of the seven individual indications that permitted data comparison., Conclusion: Median wait times for gastroenterology services continue to exceed consensus conference recommended targets and have significantly worsened since 2005.

Background: Klebsiella oxytoca is a cause of antibiotic-associated hemorrhagic colitis. Few reports of the occurrence of K oxytoca within stool exist and there is no gold standard method for its isolation., Methods: MacConkey agar was modified to culture K oxytoca. Ampicillin was added and adonitol was substituted for lactose. Rectal swabs from 200 patients being screened for vancomycin-resistant enterococci (VRE) and stool specimens from 429 patients who tested negative for Clostridium difficile cytotoxin were cultured. K oxytoca isolates were evaluated for cytotoxicity to HEp-2 cells. Available charts of K oxytoca-positive patients and a convenience sample of 93 K oxytoca-negative patients who underwent testing for C difficile cytotoxicity were reviewed retrospectively for documentation of bloody stool., Results: K oxytoca was isolated from 14 of 200 patients (7.0%) being screened for VRE; only one of the 14 isolates (7.1%) was cytotoxic. The organism was isolated from 42 of 429 patients (9.8%) tested for C difficile cytotoxicity; 10 isolates (23.8%) were cytotoxic. Differences in isolation and cytotoxicity rates between groups were not statistically significant. Two of 13 (15.4%) K oxytoca-positive patients screened for VRE, three of 27 (11.1%) K oxytoca-positive patients tested for C difficile cytotoxicity, and 11 of 93 (11.8%) patients from the convenience sample had documented bloody stool., Conclusions: A medium that greatly facilitates isolation of K oxytoca was developed. Occurrence of K oxytoca colonization was similar in the two patient populations studied and isolation of cytotoxic K oxytoca was not usually associated with hematochezia. Current understanding of the occurrence and causality of antibiotic-associated hemorrhagic colitis is insufficient for clinical laboratories to begin culturing K oxytoca and testing for cytotoxicity.

Background & Aims: The most widely quoted complication rates for colonoscopy are from case series performed by expert endoscopists. Our objectives were to evaluate the rates of bleeding, perforation, and death associated with outpatient colonoscopy and their risk factors in a population-based study., Methods: We identified all individuals 50 to 75 years old who underwent an outpatient colonoscopy during April 1, 2002, to March 31, 2003, in British Columbia, Alberta, Ontario, and Nova Scotia, Canada. Using administrative data, we identified all individuals who were admitted to hospital with bleeding or perforation within 30 days following the colonoscopy in each province. We calculated the pooled rates of bleeding and perforation from the 4 provinces. In Ontario, we abstracted the hospital charts of all deaths that occurred within 30 days following the procedure. We used generalized estimating equations models to evaluate factors associated with bleeding and perforation., Results: We identified 97,091 persons who had an outpatient colonoscopy. The pooled rates of colonoscopy-related bleeding and perforation were 1.64/1000 and 0.85/1000, respectively. The death rate was 0.074/1000 or approximately 1/14,000. Older age, male sex, having a polypectomy, and having the colonoscopy performed by a low-volume endoscopist were associated with increased odds of bleeding or perforation., Conclusions: Although colonoscopy has established benefits for the detection of colorectal cancer and adenomatous polyps, the procedure is associated with risks of serious complications, including death. Older age, male sex, having a polypectomy, and having the procedure done by a low-volume endoscopist were independently associated with colonoscopy-related bleeding and perforation.

Background: Canadian wait time data are available for the treatment of cancer and heart disease, as well as for joint replacement, cataract surgery and diagnostic imaging procedures. Wait times for gastroenterology consultation and procedures have not been studied, although digestive diseases pose a greater economic burden in Canada than cancer or heart disease., Methods: Specialist physicians completed the practice audit if they provided digestive health care, accepted new patients and recorded referral dates. For patients seen for consultation or investigation over a one-week period, preprogrammed personal digital assistants were used to collect data including the main reason for referral, initial referral and consultation dates, procedure dates (if performed), personal and family history, and patient symptoms, signs and test results. Patient triaging, appropriateness of the referral and timeliness of care were noted., Results: Over 10 months, 199 physicians recorded details of 5559 referrals, including 1903 visits for procedures. The distribution of total wait times (from referral to procedure) nationally was highly skewed at 91/203 days (median/75th percentile), with substantial interprovincial variation: British Columbia, 66/185 days; Alberta, 134/284 days; Ontario, 110/208 days; Quebec, 71/149 days; New Brunswick, 104/234 days; and Nova Scotia, 42/84 days. The percentage of physicians by province offering average-risk screening colonoscopy varied from 29% to 100%., Discussion: Access to specialist gastroenterology care in Canada is limited by long wait times, which exceed clinically reasonable waits for specialist treatment. Although exhibiting some methodological limitations, this large practice audit sampling offers broadly generalized results, as well as a means to identify barriers to health care delivery and evaluate strategies to address these barriers, with the goals of expediting appropriate care for patients with digestive health disorders and ameliorating the personal and societal burdens imposed by digestive diseases.

Background: Monitoring wait times and defining targets for care have been advocated to improve health care delivery related to cancer, heart, diagnostic imaging, joint replacements and sight restoration. There are few data on access to care for digestive diseases, although they pose a greater economic burden than cancer or heart disease in Canada. The present study compared wait times for specialist gastroenterology care with recent, evidence-based, consensus-defined benchmark wait times for a range of digestive diseases., Methods: Total wait times from primary care referral to investigation were measured for seven digestive disease indications by using the Practice Audit in Gastroenterology program, and were benchmarked against consensus recommendations., Results: Total wait times for 1903 patients who were undergoing investigation exceeded targets for those with probable cancer (median 26 days [25th to 75th percentiles eight to 56 days] versus target of two weeks); probable inflammatory bowel disease (101 days [35 to 209 days] versus two weeks); documented iron deficiency anemia (71 days [19 to 142 days] versus two months); positive fecal occult blood test (73 days [36 to 148 days] versus two months); dyspepsia with alarm symptoms (60 days [23 to 140 days] versus two months); refractory dyspepsia without alarm symptoms (126 days [42 to 225 days] versus two months); and chronic constipation and diarrhea (141 days [68 to 264 days] versus two months). A minority of patients were seen within target times: probable cancer (33% [95% CI 20% to 47%]); probable inflammatory bowel disease (12% [95% CI 1% to 23%]); iron deficiency anemia (46% [95% CI 37% to 55%]); positive occult blood test (41% [95% CI 28% to 54%]); dyspepsia with alarm symptoms (51% [95% CI 41% to 60%]); refractory dyspepsia without alarm symptoms (33% [95% CI 19% to 47%]); and chronic constipation and diarrhea (21% [95% CI 14% to 29%])., Discussion: Total wait times for the seven indications exceeded the consensus targets; 51% to 88% of patients were not seen within the target wait time. Multiple interventions, including adoption of evidence-based management guidelines and provision of economic and human resources, are needed to ensure appropriate access to digestive health care in Canada. Outcomes can be evaluated by the 'point-of-care', practice audit methodology used for the present study.
