Abstract C019: Comparing the effectiveness of different community education approaches on colorectal cancer knowledge

Abstract Introduction: Colorectal cancer (CRC) incidence and mortality varies greatly among racial/ethnic groups nationally. Community outreach and education are effective strategies to enhance knowledge of CRC and have been shown to increase screening for CRC. The University of New Mexico Comprehensive Cancer Center implements Screen to Save, a community-based CRC screening initiative through the National Outreach Network Program. During the COVID-19 pandemic, restrictions on in-person engagement led to the development and implementation of alternative delivery strategies. Our site continued in-person education as possible, and added Zoom and fully self-paced via QR code options for community member participation. Very little is known regarding the effectiveness of different delivery modes. The purpose of this research is to examine the relationship between method of education session delivery and participant CRC knowledge. Methods: Participants were recruited via community organizations, Facebook advertising, and referrals from local stakeholders. Both before and after a standardized health education session, participants completed a survey assessing their knowledge of CRC risk and screening recommendations. Participant demographics were descriptively summarized. Estimates of mean changes, and 95% confidence intervals (CI), were obtained for each content delivery type. Differences in these changes were compared using ANCOVA approaches. Results: There were 239 participants who completed the educational sessions in-person (n=81), via Zoom (n=66), or using the self-paced module (n=92), Groups did not differ significantly in composition for age (p=0.72) or gender (p=0.33), but did differ in race, ethnicity, and education level (p<0. 001). Those who participated in any delivery method improved their knowledge scores by 11.6 (95% CI: 9.9-13.3) percentage points. For in-person, Zoom, and self-paced groups, the improvements were 14.1 (95% CI: 10.6-17.6, p<0.001), 11.5 (95% CI: 9.1-13.8, p<0.001), and 9.4 (95% CI: 6.7-12.1, p<0.001) percentage points, respectively. When comparing pre vs post score differences among session types while adjusting for pre scores, and for baseline differences in race, ethnicity, and education, the differences in improvement for the three different session types were not significantly different (p=0.68). For in-person, Zoom, and self-paced groups adjusted improvements were 9.2 (95% CI: 0.5-17.5), 11.1 (95% CI: 1.9-19.8), and 10.1 (95% CI: 1.5-18.3) percentage points, respectively. Conclusion: Health education sessions delivered in person, via Zoom, and by self-paced online modules are associated with increases in participant knowledge of CRC. As Cancer Centers expand community outreach and engagement to address cancer health disparities in their catchment areas, a better understanding of the relative effectiveness of different delivery strategies is needed. Further research will help to discern population characteristics predictive of different strategies and link these approaches to screening uptake. Citation Format: Lila A.

Knowledge and Attitude of Inflammatory Bowel Disease Patients Toward Colorectal Cancer Risk, Its Management, and the Role of Healthcare Providers: A Cross-Sectional Study in the UK.

Inflammatory bowel disease (IBD) increases the risk for colorectal cancer (CRC). Limited literature exists on patients' knowledge of CRC risk and management. Attitude toward doctor-recommended management and the role of healthcare providers (HCPs) in CRC risk awareness remain unexplored. This study aimed to fill the gap in knowledge about CRC risk awareness and management in IBD patients in the UK. This cross-sectional internet-based study was conducted in April-July 2019. Adult (>18 years) IBD patients with a confirmed diagnosis for 2 years and adequate command of English language were invited from non-Natinal Health Services sources. A self-designed and piloted questionnaire with open- and closed-ended questions was used. Closed-ended data were analyzed using descriptive statistics and open-ended responses were analyzed using content analysis. Ninety-two participants (52.5% Crohn's disease and 67.5% females) responded. Around 88% knew that IBD increased CRC risk. Only 20.7% were aware of colonoscopy as the best screening tool; 88% were unaware of screening initiation time. Almost 90% would agree to a doctor's recommendation of colonoscopy. For dysplasia with 10% risk of CRC, 46.7% would not agree with colectomy. Some 48% reported to have never had a discussion about the risk of CRC in IBD with their HCPs, while 58% were not informed of the role of screening and surveillance in managing CRC risk. IBD patients were poorly aware of CRC risk management and had mixed willingness to comply with a doctor's recommendation. HCP's role in cancer knowledge dissemination was suboptimal and patients desired more information.

Colorectal Cancer-Related Knowledge, Acculturation, and Healthy Lifestyle Behaviors Among Low-Income Vietnamese Americans in the Greater Philadelphia Metropolitan Area.

Colorectal cancer (CRC) is the second and fourth most common cancer in Vietnamese American women and men, respectively. Recent research has highlighted the importance of modifiable lifestyle behaviors such as smoking, alcohol use, dietary behaviors, and physical activities in CRC prevention for the general population. However, it is not well understood how well Vietnamese Americans knew about CRC prevention and risk factors, and whether there were any disparities in knowledge within this vulnerable population. This study examined whether comprehensive measures of acculturation and knowledge of CRC risk are associated with different health behaviors, specifically physical activity, protective dietary behaviors, and risky dietary behaviors in Vietnamese Americans. We recruited 374 Vietnamese Americans aged 50 or above from community-based organizations in the Vietnamese American communities in the greater Philadelphia metropolitan area. Through a cross-sectional survey, we collected data on their knowledge of CRC prevention and risk factors, acculturation-related factors, and sociodemographic characteristics. We found limited knowledge of CRC prevention and risk factors, and suboptimal physical activity and healthy dietary behaviors in the Vietnamese Americans. We also found that higher levels of knowledge about CRC and risk factors were associated with less unhealthy diets but not with more protective diets or physical activity. Acculturation was not significantly associated with overall dietary behaviors in our study. Our findings addressed gaps in current literature concerning the impact of knowledge about CRC risk factors and acculturation on different dimensions of dietary behaviors as well as physical activity. Research and practical implications were discussed.

N04 Knowledge, attitude and perception of inflammatory bowel disease patients towards colorectal cancer risk, its management and the role of healthcare providers: a cross-sectional study in the UK

Abstract Background Inflammatory bowel disease (IBD) increases the risk of colorectal cancer (CRC) and requires specialised cancer risk management. Although literature exists on general disease-related knowledge in IBD patients, limited studies have assessed IBD patients’ knowledge of CRC risk and its management. Consequently, patient perception of the role of a healthcare provider (HCP) in patient education of CRC risk and their attitude towards recommended risk management has not been assessed in UK IBD patients. Methods We conducted a cross-sectional online survey with IBD patients recruited via charity sources from April-July 2019. Adult patients (>18 years) with a confirmed diagnosis of IBD for 2 years and adequate command of English language were included. A self-designed and piloted questionnaire with open and closed-ended questions was used. Closed-ended data were analysed using descriptive statistics and open-ended responses were analysed using content analysis. Fischer’s exact test and bivariate logistic regression were used to test for association between knowledge and patient demographics. Results 92 participants, including 52.5% CD and 67.5% females, responded. 88% knew that IBD increases CRC risk. The mean fear of CRC risk (0–10 visual analogue scale) was 6.37 (SD ± 2.8). One-fifth were aware of colonoscopy as the best screening tool; 88% were unaware of screening initiation time. 90% would agree to their doctor’s recommendation of colonoscopy to ensure early cancer diagnosis and treatment. For dysplasia with 10% risk of CRC, 46.7% would not agree to colectomy mainly due to 10% risk of CRC not being high enough to undergo surgery. Forty-eight per cent of participants said that they never had a discussion about increased CRC risk in IBD with their doctor. Almost two-thirds were not informed about the role of screening/surveillance in cancer. Two-thirds were satisfied with the information provided by their HCP. Overall, patients desired more information about their individualised cancer risk and services available for managing the increased risk. Conclusion IBD patients are well informed about IBD-associated CRC risk, feared this risk greatly but were poorly aware of screening initiation time. HCP’s role in cancer knowledge dissemination was sub-optimal and patients desired more knowledge. We need deeper understanding of patients’ educational needs related to CRC.

399P - Prevalence of colorectal cancer risk factors in apparently healthy adults in Suluhan Village, Bali

BackgroundCurrently in Indonesia, colorectal cancer (CRC) is the third most commonly occurring cancer in men and the fourth in women. CRC is mostly diagnosed in the advanced stage, it’s probably caused by the difficulties in detecting colorectal cancer. Identifying risk factors of CRC is very crucial to prevent CRC. CRC risk is expected to rise continually due to dietary patterns, smoking, lack of physical activities, and other practices. This study describes the prevalence of risk factors for CRC in healthy residents of Suluhan village, Bangli District, Bali Province. MethodsA pre-experimental cross-sectional study-based community was conduct on 18th – 19th May 2019 in Suluhan village to collect data from 77 healthy residents using validated questionnaire. We measured sociodemographic characteristics, physical activity, dietary habits, and lifestyle as risk factors of CRC. Analysis of data using chi-square with p-value ≤0.05 is categorized as significant. Results77 respondents were involved in this study with a mean age of 41.94±9.448 years. The majority of participants were female (61 %). Mostly the residents didn’t know CRC (80.6%). The commonest risk factors for CRC among the participants were overconsumption of red meat (2 times/week and >3 times/week) (67.6 %), overweight and obesity (62.4 %), limited consumption of vegetables (62.3 %), low of physical activities (44.1%), smoking (28.6%), and limited consumption of diet fiber (10.4%). Lack of physical activity was found significantly higher in females (p = 0,000), otherwise smoking (p = 0,000) is higher in males. ConclusionsWe conclude that the highest risk factor of CRC in Suluhan village is the overconsumption of red meat, followed by overweight and obesity, limited consumption of vegetables, low physical activities, smoking, and limited consumption of diet fiber sequentially. Dietary and lifestyle risk factors for CRC are prevalent in Suluhan village and likely to increase CRC incidence if educational interventions are not implemented. Greater attention in improving residents’ knowledge of CRC risk is needed to prevent CRC in Suluhan village. Legal entity responsible for the studyThe authors. FundingHas not received any funding.

BRCA1 and BRCA2 mutations and the risk for colorectal cancer.

Women who carry a BRCA1 or BRCA2 mutation are at high risk of breast and ovarian cancer, and may be at moderately increased risk of other cancer types. This review examines studies to date that have evaluated the risk of BRCA1 and BRCA2 mutations for colorectal cancer. Accurate knowledge of colorectal cancer risk in BRCA1/2 carriers is important, because colonoscopy screening can prevent colorectal cancer through the removal of adenomatous polyps. Most studies that have identified an increased risk for colorectal cancer in BRCA1/2 mutation carriers were in high-risk cancer families, while studies that found no association were conducted in specific populations and involved the analysis of founder mutations. A recent prospective study of 7015 women with a BRCA1 or BRCA2 mutation identified significant fivefold increased risk of colorectal cancer among BRCA1 mutation carriers younger than 50 years [standardized incidence ratio (SIR): 4.8; 95% CI: 2.2-9], but not in women with a BRCA2 mutation or in older women. Based on this evidence, women with BRCA1 mutations should be counseled about their increased risk for early-onset colorectal cancer, and offered colonoscopy at 3- to 5-year intervals between the ages of 40 and 50 years, and should follow population guidelines thereafter.

Patient attitudes and issues in colon cancer screening.

Colorectal cancer (CRC) is the third leading cause of cancer death in the United States, and is largely preventable by CRC screening (CRCS). Participation in CRCS, however, is much lower than participation in other forms of preventive care. Many reasons for low rates of participation have been identified, and can be generally divided into provider- and patient-specific issues. Lack of a provider recommendation is a well-established and widely reported patient barrier to CRCS. Numerous patient-specific issues have been identified, ranging from fear of CRCS test results to lack of knowledge about individual risk for CRC and inadequate resources to complete CRCS. This article discusses the impact of patient attitudes and issues toward CRCS, with particular attention to modifiable psychosocial factors, the importance of patient preferences for one CRCS test over another, knowledge of CRC risk, and the impact of educational tools on patient compliance with CRCS.

Abstract B79: Assessing colorectal cancer screening behaviors and knowledge among at-risk Hispanics in southern New Mexico.

Abstract Introduction: Colorectal cancer (CRC) mortality rates in New Mexico have not decreased as much as the US national rates, and mortality rates among Hispanics in the state are higher than among this ethnic group in the US. Methods: A Colorectal Cancer Knowledge Assessment Survey (KAS) was administered in either English or Spanish to 247 individuals attending community events and health fairs throughout southern New Mexico. A subset of these individuals completed an electronic CRC risk assessment managed by National Institutes of Health (NIH) National Cancer Institute (NCI). Data analysis was performed using SPSS (Statistical Package for the Social Sciences) to test for significant differences in knowledge, and/or screening rates based on ethnicity. Results: There were significant differences among participants > 50 years old based on ethnicity for knowledge about CRC, physician discussions and recommendations, and screening rates. In all cases, with the exception of knowledge of CRC risk, Hispanics of CRC screening age, were less likely to be recommended for screening by their physician, less likely to discuss CRC screening, knew less about CRC and about the different types of screening modalities, and reported CRC screening in the past at about half the rate of their non-Hispanic white counterparts. Conclusions: The increased mortality rates for New Mexican Hispanics with colorectal cancer are likely due to the very low screening rates, which in turn are related to the lack of knowledge about this condition. Expanded education and outreach efforts for minority populations to increase knowledge and awareness of prevention and screening behaviors is critical.

Colorectal cancer: a survey of community beliefs and behaviours in Victoria.

To document self-reported beliefs and behaviours in relation to colorectal cancer (CRC) and screening for CRC. A stratified random sample was selected from the telephone directory, and structured telephone interviews were conducted using a computer-assisted telephone interviewing system. 500 men and 500 women aged 40-60 years, 70% randomly selected from the Melbourne metropolitan area and 30% from rural Victoria. The response rate to the initial telephone invitation of 1569 eligible people was 63.7%. Awareness of and experience with CRC; knowledge of CRC risk, risk reduction behaviour, and screening tests for CRC; willingness to have screening tests for CRC; and test preferences. The people surveyed were relatively unaware of their personal risk of CRC, despite 61% (95% CI, 57%-65%) knowing someone who had CRC. Although 51% (95% CI, 48%-54%) could not name any CRC screening test, 68% (95% CI, 65%-71%) knew of the value of a high fibre diet in prevention. However, 67% (95% CI, 64%-70%) thought it was unlikely they would have a screening test for CRC in the next two years, but 64% (95% CI, 61%-67%) considered that some person could influence their decision to have a test, 60% (95% CI, 56%-64%) stating that they would be influenced by a doctor. Faecal occult blood testing and sigmoidoscopy were equally acceptable. In general, women were more knowledgeable than men. There were no systematic age or urban/rural differences. There is a variable understanding of CRC in the community. Although prevention is well understood, this is not true of screening. General practitioners are likely to be influential in the uptake of any screening programs.
