Book Adherence to Rescreening for Colorectal Cancer with Faecal Occult Blood Testing

Download or read book Adherence to Rescreening for Colorectal Cancer with Faecal Occult Blood Testing written by Amy Claire Duncan and published by . This book was released on 2012 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis aimed to describe and predict adherence to Faecal Occult Blood Test (FOBT) rescreening recommendations in South Australia. Specifically this thesis aimed to determine the relevance of social cognitive variables for explaining variations in rescreening adherence. FOBT screening for colorectal cancer (CRC) is recommended every one to two years for those over the age of 50; reductions in incidence and mortality from CRC are dependent on continued compliance with these guidelines. Whilst there has been substantial research on factors associated with initial screening participation, there has been very little research conducted on how to encourage rescreening adherence (i.e., continued participation in annual or biennial screening offers). The few studies that have examined predictors of rescreening have, to date, limited their exploration to demographic and health systems factors. This thesis aims to determine the relevance of the inclusion of behavioural factors previously associated with initial screening (i.e., social cognitive variables) for explaining rescreening and also to explore potential new predictors of rescreening not previously examined in CRC rescreening research. The thesis used a sequential, mixed-methods research design to address the aims. Three separate studies, one qualitative and two quantitative, were used to explore predictors of adherence to FOBT rescreening. The three studies are presented as three separate papers in the thesis. Study one used 17 semi-structured interviews to explore rescreening participants' past experience with FOB testing. Exploratory thematic analysis was used to determine factors relevant for inclusion in a subsequent questionnaire. The questionnaire was then administered to 4000 potential participants within the target age range for FOBT screening (50-75 years) in South Australia. Study two analysed questionnaire data to determine associations with stage of readiness (intention) for rescreening. Following survey completion, respondents (survey response rate of 49%) were provided with three annual offers to screen with FOBT. Data collected during the questionnaire phase were used to identify variables predictive of rescreening adherence. Univariate and multivariate modelling were used to determine associations with intention and adherence. Results of study one revealed that many of the factors previously associated with initial screening (e.g., perceived barriers, benefits and social influence) were associated with rescreening. However, specific barriers, for example, maintaining a screening routine, were identified for rescreening. In addition previous screening experience appeared to influence attitudes toward future participation i.e., improved participants self-efficacy with regard to future participation and reinforced the perceived benefits of participation. Study two found that almost 30% of prior screeners were non-adherent with rescreening. Social cognitive (self-efficacy, perceived barriers and benefits, social influences, implementation intentions) and demographic/background variables (age, knowledge, and health insurance coverage) were associated with rescreening intention. Conversely, in study three, only few social cognitive variables (perceived barriers, self-efficacy and response efficacy) were marginally associated with screening adherence across three rounds of screening. The demographic variables gender, insurance and marital status better differentiated patterns of adherence. When a measure of satisfaction with prior FOBT screening was added to the multivariate models in study three, none of the social cognitive variables significantly predicted adherence. Satisfaction with prior screening substantially increased rescreening intention and adherence by 13% and 42% in studies two and three respectively. Results of the thesis indicate that although social cognitive variables differentiated intentions to rescreen, when demographic variables and satisfaction with prior screening were held constant, social cognitive variables did little to predict rescreening adherence. Satisfaction with prior screening was an important predictor of both rescreening intention and adherence. Exploration of the factors contributing to satisfaction with screening may provide an important opportunity to modify and improve screening services to encourage rescreening. Several demographic variables were also found to have a substantial impact on intention and adherence. An investigation of how these demographic and background factors interact with social cognitive variables may allow for greater tailoring of messages to encourage rescreening.

Book Implementing Colorectal Cancer Screening

Download or read book Implementing Colorectal Cancer Screening written by Institute of Medicine and published by National Academies Press. This book was released on 2008-12-01 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: The IOM's National Cancer Policy Board estimated in 2003 that even modest efforts to implement known tactics for cancer prevention and early detection could result in up to a 29 percent drop in cancer deaths in about 20 years. The IOM's National Cancer Policy Forum, which succeeded the Board after it was disbanded in 2005, continued the Board's work to outline ways to increase screening in the U.S. On February 25 and 26, 2008, the Forum convened a workshop to discuss screening for colorectal cancer. Colorectal cancer screening remains low, despite strong evidence that screening prevents deaths. With the aim to make recommended colorectal cancer screening more widespread, the workshop discussed steps to be taken at the clinic, community, and health system levels. Workshop speakers, representing a broad spectrum of leaders in the field, identified major barriers to increased screening and described strategies to overcome these obstacles. This workshop summary highlights the information presented, as well as the subsequent discussion about actions needed to increase colorectal screening and, ultimately, to prevent more colorectal cancer deaths.

Book Colorectal Cancer Screening

Download or read book Colorectal Cancer Screening written by Aasma Shaukat and published by Springer. This book was released on 2015-03-14 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides a comprehensive overview of quality metrics and methods used to improve quality for all major modalities of CRC screening. It introduces the readers to the evidence of effectiveness behind various CRC screening modalities: stool-based tests (Fecal Occult Blood, Fecal Immunochemical and Fecal DNA tests), flexible sigmoidoscopy, colonoscopy and CT colonography. In-depth chapters review the latest guidelines for CRC screening, compare differences among the five major national guidelines, and highlight the need for valid quality and cost indicators. While the main focus of this volume is on colonoscopy, since most quality indicators and analyses have focused on this modality of screening and surveillance, one chapter is devoted to quality indicators of other screening modalities. Differences between process and outcome measures are also highlighted and a small but valid set of recommended national measures are listed. Written by experts in the field, Colorectal Cancer Screening: Quality and Benchmarks is an important and useful resource written for gastroenterologists, primary care physicians, general and colorectal surgeons, family physicians, and investigators with research focus in screening and quality metrics.

Abstract: Background Colorectal cancer (CRC) is one of the most common cancers with high morbidity and mortality among both genders and yet it carries a better prognosis when detected early. Colorectal cancer screening using faecal occult blood test (FOBT) is proven to be cost-effective, however worldwide FOBT uptake rate is suboptimal which directly affects the cost-effectiveness of the screening program. Identifying those factors that influence the uptake of colorectal cancer screening using FOBT will allow implementation of relevant measures when planning a population based screening program. Methods A structured electronic search using PubMed and Medline was conducted in order to identify studies that included factors influencing the uptake of CRC screening by using FOBT. Qualities of included studies were assessed by quality assessment checklist STROBE. Results Factors that contributed to the low uptake rate of CRC screening by FOBT were identified and summarized. They were broadly divided into 3 groups. Demographic factors: age, gender, social economic status, insurance status and education, for ethnicity, employment status and obesity further studies in the future may be needed. Subject factors: subject's attitudes and knowledge towards CRC screening, type of FOBT screening, health concerned behavior, frequency of clinical visit and physiciancomment. Provider factors: health care system factor and physicians' factors. Conclusion Different factors, in particular those factors that were associated with low FOBT uptake rate in CRC screening, were reviewed and summarized in this paper. With the continuous effort from worldwide as well as local investigators, timely measures can be implemented to tackle this deathly disease and to ensure cost effectiveness of a screening program.

Available in PDF, EPUB and Kindle. Book excerpt: BACKGROUND: The U.S. Preventive Services Task Force requested a decision analysis to inform their update of the recommendations for colorectal cancer (CRC) screening. OBJECTIVE: To assess life-years gained and colonoscopy requirements for CRC screening strategies and identify a set of recommendable screening strategies. DESIGN: Decision analysis using two CRC microsimulation models from the Cancer Intervention and Surveillance Modeling Network. DATA SOURCES: Derived from recent published literature on test characteristics of single use applications of various screening strategies. TARGET POPULATION: U.S. average-risk 40-year-old population. PERSPECTIVE: Societal. TIME HORIZON: Lifetime. INTERVENTIONS: Fecal occult blood tests (FOBTs), flexible sigmoidoscopy, or colonoscopy screening beginning at age 40, 50, or 60 and stopping at age 75 or 85 with screening intervals of 1, 2, or 3 years for FOBT and 5, 10, or 20 years for sigmoidoscopy and colonoscopy. OUTCOME MEASURES: Number of life-years gained compared with no screening and number of colonoscopies and non-colonoscopy tests required. RESULTS OF BASE-CASE ANALYSIS: Beginning screening at age 50 was consistently better than age 60. Lowering the stop age from 85 to 75 decreased life-years gained by 1% to 4%, while colonoscopy use fell by 4% to 15%. Assuming equally high adherence, four strategies provided comparable life-years gained, namely 10-yearly colonoscopy, annual Hemoccult SENSA or fecal immunochemical test, and 5-yearly flexible sigmoidoscopy in conjunction with Hemoccult SENSA every 2 to 3 years. Annual Hemoccult II alone and 5-yearly flexible sigmoidoscopy alone were less effective. RESULTS OF SENSITIVITY ANALYSIS: The results were most sensitive to beginning screening at age 40. LIMITATIONS: Stopping age for screening was based only on chronological age. CONCLUSIONS: Our findings support CRC screening from ages 50 to 75 with annual screening with a high sensitivity FOBT, 10-yearly colonoscopy, or high sensitivity FOBT every 2 to 3 years with a 5-yearly flexible sigmoidoscopy.

Book Evaluating Test Strategies for Colorectal Cancer Screening   Age to Begin  Age to Stop  and Timing of Screening Intervals

Download or read book Evaluating Test Strategies for Colorectal Cancer Screening Age to Begin Age to Stop and Timing of Screening Intervals written by U. S. Department of Health and Human Services and published by CreateSpace. This book was released on 2013-06-26 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite recent declines in both incidence and mortality, colorectal cancer (CRC) remains the second most common cause of cancer death in the United States. Screening for CRC reduces mortality through the detection of malignancies at earlier, more treatable stages, as well as through the identification and removal of adenomatous polyps (asymptomatic benign precursor lesions that may lead to CRC). There are a number of tests currently available for screening, such as fecal occult blood testing (FOBT), flexible sigmoidoscopy, and colonoscopy. Screening with FOBT (Hemoccult II) has been shown to reduce CRC mortality by 15% to 33% in randomized controlled trials and screening with more sensitive FOBTs, flexible sigmoidoscopy, colonoscopy or combinations of these tests may reduce the burden of CRC even more. In the absence of adequate clinical trial data on several recommended screening strategies, microsimulation modeling can provide guidance on the risks, benefits, and testing resources required for different screening strategies to reduce the burden of CRC. In July 2002, the US Preventive Services Task Force (USPSTF) concluded that there was sufficient evidence to recommend strongly that all average-risk adults 50 years of age and older should be offered CRC screening. However, the logistics of screening such as the type of screening test, screening interval, and age to stop screening were not evaluated in terms of the balance of benefits and potential harms. The USPSTF has again addressed CRC screening recommendations with a systematic review of the evidence on screening tests. For this assessment, the Task Force requested a decision analysis to project expected outcomes of various CRC screening strategies. Two independent microsimulation modeling groups from the Cancer Intervention and Surveillance Modeling Network (CISNET), funded by the National Cancer Institute, used a comparative modeling approach to compare life-years gained relative to resource use of different CRC screening strategies.
