..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...

..To evaluate the evidence concerning gFOBT kits and to develop gFOBT standards to be implemented by the Ontario Colorectal Cancer (CRC) Screening Program (the "Program")...

..The recommendations will form the basis of the quality assurance program for colonoscopy delivered in support of Ontario's CRC screening program...

..However, CRCs do occur in individuals after a negative colonoscopy. We investigated whether the colonoscopy volume and specialty of the endoscopists who perform the exam are associated with CRC after a negative complete colonoscopy...

..Our objective was to evaluate the association between regional colonoscopy rates and death from colorectal cancer (CRC)...

..To determine factors that influence awareness of, and readiness to undergo, fecal occult blood testing (FOBT) for colorectal cancer (CRC) screening...

..Regulation of these facilities is variable, and concerns regarding the quality of procedures in nonhospital (NH) settings have been raised. Further study is needed to better understand endoscopic practice in these facilities...

..A large percentage of these patients live at least 5 years after diagnosis, but it is unknown whether their rate of hospitalizations after this 5-year mark is comparable to the general population...

..This information will be used to guide program strategies for increasing screening uptake...

..The rate of new or missed colorectal cancer (CRC) after colonoscopy and their risk factors in usual practice are unknown. Our objective was to evaluate the rate and risk factors in a population-based study...

..We conducted a population-based study to determine the colonoscopy completion rate and to identify factors associated with incomplete procedures...

..With the increasing use of colonoscopy there is growing concern about the quality of these procedures...

..We examined the association between the concomitant use of warfarin and nonselective nonsteroidal anti-inflammatory drugs (NSAIDs) or selective COX-2 inhibitors in older adults hospitalized for upper GI hemorrhage...

..Given the high burden of CRC in Canada a major opportunity exists to improve the health of Canadians by increasing our screening efforts...

....

..Colonoscopy is advocated for screening and prevention of colorectal cancer (CRC), but randomized trials supporting the benefit of this practice are not available...

..This study compares the long-term survival of young adults with colorectal cancer who lived a minimum of 5 years after diagnosis with a cancer-free control population...

..Our objective was to estimate the annual incidence of CRC within 7 yr following FS and to identify factors associated with incident CRC in those with a negative FS...

..This population-based study describes the incidence of, associated patient risk factors for, and regional variation in EA/GCA in Ontario, Canada...

..The incidence of colorectal cancer (CRC) overall is reduced for up to 10 years after a negative colonoscopy. The objective of this research was to determine the incidence of proximal and distal CRC after a negative complete colonoscopy...

..We aimed to describe trends in medication use, associated health services, and outcomes (hospitalization and surgical rates) between 1994-2007 in children with IBD...

..To conduct a population-based study on the provision of large bowel endoscopic services in Ontario...

..This study's objective was to identify nonpayor factors (patient, physician, institution) associated with anesthesiologist assistance at colonoscopy...

..S. populations. The items can be used to evaluate and compare psychosocial correlates across U.S. and Canadian samples. Additional research is needed to show invariance for other ethnocultural and national subgroups...

..However, evidence from population-based studies is lacking on the time period over which monitoring is needed to detect these adverse events...

..We investigated whether characteristics of endoscopists, determined from administrative data, are associated with development of postcolonoscopy colorectal cancer (PCCRC)...

..These findings should encourage the development of further Canadian workplace colorectal cancer-screening awareness programs...

..CONCLUSIONS: Much greater emphasis on screening is needed since approximately 20% of patients with a new diagnosis of colorectal cancer in 1999-2001 presented with OPE...

..Only one-fifth of people in the screening-eligible age group received any colorectal investigation. Further work is needed to determine the reason for this low rate and to explore whether it affects CRC mortality...

..Despite highest-quality evidence that early detection of colorectal cancer (CRC) can lead to reduced mortality, no organized CRC screening programs exist in Canada...

..To examine healthcare utilization according to family income in children with inflammatory bowel disease (IBD)...

..We created reporting guidelines for studies validating administrative data identification algorithms and used them to assess the quality of reporting of validation studies in the literature...

..The low prevalence of colorectal cancer screening among the target population suggests the need for an increased awareness of the public health importance of colorectal cancer screening...

..Population-based CRC screening is needed to address these adverse outcomes...

..The Ontario FOBT Project is a pilot study of fecal occult blood testing (FOBT) for colorectal cancer screening conducted among age-eligible volunteers (50 to 75 years) in 12 of 37 public health regions in Ontario...

..Fertility is an important issue for long-term survivors of malignancies developing during reproductive years. We designed a population-based study to investigate childbirth in female young adult survivors of non-gynecologic malignancies...

....

..Given greater specimen instability with the use of FIT, a pilot study should be undertaken to determine how to implement the FIT in Ontario...

..The geographic variation in the application of this procedure in patients with colon cancer suggests that local organizational structures and processes of care may play an important role in patient treatment and, therefore, prognosis...

..Our objective was to evaluate the rate of new or missed CRC following DCBE and the associated risk factors in a population-based study...

..To describe the processes of care for gastric cancer in Ontario and identify areas in which care and possibly survival can be improved...

..Anal cancer screening may be considered in HIV-infected men who have sex with men because they are at increased risk. Cancer screening can provoke anxiety, which may lead to poorer screening compliance...

..As health human resource strategies continue to evolve, it is believed that lessons learned from experience make an important contribution to the knowledge of how nontraditional health services can be organized and delivered...

..CONCLUSIONS: Among persons undergoing resection for right-sided colon cancer, the miss rate of colonoscopy for detecting cancer in usual clinical practice was 4.0%...

..Future studies are needed to discover what aspects of clinical management explain these differences...

..We encourage other groups to assess the efficiency of their hospital-based endoscopy units...

..CONCLUSIONS: The GI tolerability of valdecoxib is superior to that of nonspecific NSAIDs, and therefore can potentially have a favorable impact on patient quality of life...

..The United States had the most variation in the number of gastroenterologists per 100,000 of the population among states...

..0 to 28.7 per 100,000 persons. Significant regional variation exists for antireflux surgery across Ontario, suggesting that its appropriate role in the management of GERD remains ill-defined...
