Knowledge and social engagement change in intention to be screened for colorectal cancer

Educational interventions to improve bowel cancer awareness and screening in Organisation for Economic Co-operation and Development countries: A scoping review

Objectives

Summarise theory informed educational interventions for improving bowel cancer awareness and screening.

Methods

A search was conducted in PubMed, EMBASE, Web of Science and CINAHL. English studies from 2016 to 2022 which implemented community-based bowel cancer awareness and/or screening education interventions for adults in Organisation for Economic Co-operation and Development countries were included.

Results

Sixty-two studies were included, 32 measured both screening and awareness (24 measured screening only, 6 measured awareness only). Education interventions were grouped and summarised in five education types: lay community health education/counselling (n = 28), education material (n = 5), health professional education/counselling (n = 10), mass media (n = 5) and other (n = 19). Other included education interventions which did not fit into the four types previously mentioned. Six studies tested more than one education type. Each type within these studies were reported/summarised separately within the appropriate education type. Lay educators resulted in improved awareness and screening. Brochures were effective education materials for screening and combined with lay educators resulted in increased awareness. State-wide mass media campaigns significantly improved screening uptake for up to 2-months post-campaign. Fear and loss-framed messaging improved screening intentions compared to humour or gain-based messaging. Decision aids had limited improvements in awareness. Facebook campaign and telephone counselling had limited improvements in screening.

Conclusions

Lay community health educators, brochures, and mass media campaigns occurring multiple times a year may be effective interventions in improving screening and/or awareness. Such approaches should be considered when developing community education. Education interventions should include multiple components suggested above to maximise improvements of awareness and screening.

Long-term trends in incidence, mortality and burden of liver cancer due to specific etiologies in Hubei Province

Liver cancer, a chronic non-communicable disease, represents a serious public health problem. Long-term trends in the burden of liver cancer disease are heterogeneous across regions. Incidence and mortality of liver cancer, based on the Global Burden of Disease, were collected from the Chinese Centre for Disease Control and Prevention. Age-period-cohort model was utilized to reveal the secular trends and estimate the age, period and cohort effects on primary liver cancer due to specific etiologies. Both the age-standardized incidence and mortality rate of liver cancer in Hubei province were on the rise, although there were discrepancies between gender groups. From age-period-cohort analysis, both incidence and mortality of liver cancer due to Hepatitis B virus were the highest in all age groups. The incidence of all liver cancer groups increased with time period in males, while this upward trend was observed in females only in liver cancer due to alcohol use group. Cohort effects indicated the disease burden of liver cancer decreased with birth cohorts. Local drifts showed that the incidence of liver cancer due to specific etiologies was increasing in the age group of males between 40 and 75 years old. The impact of an aging population will continue in Hubei Province. the disease burden of liver cancer will continue to increase, and personalized prevention policies must be adopted to address these changes.

Changes in colorectal cancer knowledge and screening intention among Ohio African American and Appalachian participants: The screen to save initiative

African Americans and Appalachians experience greater incidence and mortality rates of colorectal cancer due to factors, such as reduced prevalence of screening. An educational session (the Screen to Save Initiative) was conducted to increase intent to screen for colorectal cancer among African Americans and Appalachians in Ohio. Using a community-based approach, from April to September 2017, 85 eligible participants were recruited in Franklin County and Appalachia Ohio. Participants completed a knowledge assessment on colorectal cancer before and after participating in either an educational PowerPoint session or a guided tour through an Inflatable Colon. Logistic regression models were used to determine what factors were associated with changes in colorectal cancer knowledge and intent to screen for colorectal cancer. The majority (71.79%) of participants gained knowledge about colorectal cancer after the intervention. Multivariate results showed that race (OR = 0.30; 95% CI: 0.11–0.80 for African Americans versus White participants) and intervention type (OR = 5.97; 95% CI: 1.94–18.43 for PowerPoint versus Inflatable Colon) were associated with a change in knowledge. The association between education and intent to screen was marginally statistically significant (OR = 0.42; 95% CI: 0.16–1.13 for college graduate versus not a college graduate). A change in colorectal cancer knowledge was not associated with intent to screen. Future educational interventions should be modified to increase intent to screen and screening for colorectal cancer. Further research with these modified interventions should aim to reduce disparities in CRC among underserved populations while listening to the voices of the communities.

Scripted tours through a giant inflatable colon: An innovative and effective educational tool in urban communities

Colorectal cancer (CRC) is the second leading cause of cancer-related death among men and women in the US and mortality rates are increasing among young adults. Although CRC is largely preventable with screening and often curable when detected at an early stage, many age-appropriate individuals remain unscreened or are not currently up-to-date with screening. We aimed to examine the impact of providing guided, scripted tours through an inflatable colon on three domains: CRC knowledge, likelihood of communicating about CRC with others, and the intention to be screened for CRC in a diverse, urban population. The inflatable walk-through colon was exhibited at five community events in Franklin County, Ohio between March 2015 and August 2016. A pre and posttest research design and composite scores were stratified into three age groups (<45 years, 45-49 years and ≥ 50 years of age). Descriptive statistics were used to describe and compare demographic characteristics. Logistic regression was used to examine potential associations between demographic factors and the three outcomes of interest. These tours led to statistically significant increases in CRC knowledge, communication, and intention to undergo CRC screening among participants in all three age cohorts. In addition, the intention of undergo screening after a tour among individuals<45 years of age were nearly three times that of those older than 50 (OR = 2.66; 95%CI = 1.49-4.75). Overall, this study supports the use of scripted tours through an inflatable colon exhibit as a potentially effective intervention to increase age-appropriate CRC screening uptake.

Giant Inflatable Colon Model Enhances Lebanese Community Knowledge and Intention for Colorectal Cancer Screening

PURPOSE

To assess the knowledge and intention for colorectal cancer (CRC) screening within the Lebanese community before and after a guided tour through an inflatable colon model.

METHODS

The Cancer Prevention and Control Program, Naef K. Basile Cancer Institute at the American University of Beirut Medical Center in collaboration with AMALOUNA educational nongovernmental organization launched awareness campaigns during which a walk-through inflatable colon was displayed. Pre- and post-surveys related to the age of screening, risk factors, symptoms, and CRC prevention were collected anonymously before and after touring the inflatable colon to assess the effectiveness of this educational tool.

RESULTS

Compiled data collected from 782 participants revealed that older age and higher education were predictors of favorable CRC screening knowledge and behaviors before entering the inflatable colon. Interestingly, touring the inflatable colon model significantly improved participants’ awareness and knowledge about CRC. Most importantly, it increased their willingness for screening and social engagement and comfort discussing and promoting CRC screening.

CONCLUSION

Overall, these results indicate that the interactive colon is an effective educational tool that can make a positive impact by improving the community CRC awareness and interest in CRC screening. They also highlight the importance of such educational efforts conducted in the community to create more awareness about CRC and emphasize the importance of its prevention.

Knowledge of colorectal cancer screening guidelines and intention to obtain screening among nonadherent Filipino, Hmong, and Korean Americans

BACKGROUND

Nonadherence to colorectal cancer (CRC) screening among Asian Americans is high but not well understood. This study examined correlates of screening intention among Filipino, Hmong, and Korean Americans who were nonadherent to CRC screening.

METHODS

Using cross-sectional, preintervention survey data from 504 Asian Americans (115 Filipinos, 185 Hmong, and 204 Koreans) aged 50-75 years who were enrolled in a multisite cluster randomized controlled trial of lay health educator intervention, we analyzed correlates of self-reported CRC screening nonadherence, which was defined as not being up-to-date for fecal occult blood test, sigmoidoscopy, or colonoscopy.

RESULTS

Only 26.8% of participants indicated intention to obtain screening within 6 months (Hmong: 12.4%; Korean: 30.8%; and Filipino: 42.6%; P < .001). Only one third of participants had undergone a prior screening, and a majority did not know that screening is a method of CRC prevention method (61.3%) or had any knowledge of CRC screening guidelines (53.4%). Multivariable analyses revealed that patient-provider ethnicity concordance, provider's recommendation of screening, participants' prior CRC screening, perceived severity and susceptibility of CRC, and knowledge of guidelines were positively associated with screening intention. Specifically, knowing one or more screening guidelines doubled the odds of screening intention (adjusted odds ratio, 2.38; 95% confidence interval, 1.32-4.28). Hmong were less likely to have screening intention than Filipinos, which was unexplained by socio-demographics, health care factors, perceived needs for CRC screening, or knowledge of screening guidelines.

CONCLUSION

CRC screening intention among nonadherent Filipino, Hmong, and Korean Americans was low. Targeting knowledge of CRC screening guidelines may be effective strategies for increasing CRC screening intention among nonadherent Asian Americans. Cancer 2018;124:1560-7. © 2018 American Cancer Society.

Leveraging system sciences methods in clinical trial evaluation: An example concerning African American women diagnosed with breast cancer via the Patient Navigation in Medically Underserved Areas study

Background

Systems science methodologies offer a promising assessment approach for clinical trials by: 1) providing an in-silico laboratory to conduct investigations where purely empirical research may be infeasible or unethical; and, 2) offering a more precise measurement of intervention benefits across individual, network, and population levels. We propose to assess the potential of systems sciences methodologies by quantifying the spillover effects of randomized controlled trial via empirical social network analysis and agent-based models (ABM).

Design/methods

We will evaluate the effects of the Patient Navigation in Medically Underserved Areas (PNMUA) study on adult African American participants diagnosed with breast cancer and their networks through social network analysis and agent-based modeling. First, we will survey 100 original trial participants (50 navigated, 50 non-navigated) and 150 of members of their social networks (75 from navigated, 75 non-navigated) to assess if navigation results in: 1) greater dissemination of breast health information and breast healthcare utilization throughout the trial participants’ networks; and, 2) lower incremental costs, when incorporating navigation effects on trial participants and network members. Second, we will compare cost-effectiveness models, using a provider perspective, incorporating effects on trial participants versus trial participants and network members. Third, we will develop an ABM platform, parameterized using published data sources and PNMUA data, to examine if navigation increases the proportion of early stage breast cancer diagnoses.

Discussion

Our study results will provide promising venues for leveraging systems science methodologies in clinical trial evaluation.

Association Between Social Engagement and Cancer Screening Utilization in a Community-Dwelling Chinese American Older Population

Objectives: This study aims to examine the association between social engagement and cancer screening utilization among a Chinese American older population. Method: Data were drawn from the Population Study of Chinese Elderly (PINE). In total, 3,157 Chinese older adults enrolled in this study. Cancer screening utilization was assessed by asking whether participants had utilized cancer screenings. Social engagement was measured with 16 questions. Results: After controlling for potential confounders, a higher level of social engagement was associated with increased utilization in blood stool test (OR 1.03, [1.02, 1.05]), colonoscopy (OR 1.02, [1.01, 1.03]), mammography (OR 1.06, [1.05, 1.08]), Pap test (OR 1.04, [1.03, 1.06]), and prostate specific antigen (PSA) test (OR 1.03, [1.01, 1.05]). Compared with those with low levels of social engagement, older adults with high levels of social engagement were more likely to have utilized a blood stool test (OR 1.85, [1.46, 2.35]), a colonoscopy (OR 1.37, [1.09, 1.72]), a mammography (OR 3.05, [2.25, 4.14]), and a Pap test (OR 1.99, [1.49, 2.66]), but not more likely to have utilized a PSA test (OR 1.40, [0.97, 2.03]). Conclusion: This study underscores the association between active social engagement and increased utilization of cancer screening among a Chinese American older population. Improving social engagement could be helpful in promoting cancer screening utilization.

Using a Culturally Tailored Intervention to Increase Colorectal Cancer Knowledge and Screening among Hispanics in a Rural Community

Background: Disparities in colorectal cancer incidence and mortality rates exist among racial/ethnic minorities, especially those living in rural areas. There is an urgent need to implement interventions to improve colorectal cancer screening behaviors among such groups, particularly those living in rural areas in the United States.Methods: From a rural community of Hispanics, we recruited participants to attend home-based promotor(a)-led "home health parties" in which participants were taught about colorectal cancer screening; participants ages 50 and older were given a free fecal occult blood test (FOBT) kit to complete on their own. A pre- and posttest design was used to assess changes in colorectal cancer awareness, knowledge, and screening at baseline and at 1-month follow-up after the intervention.Results: We observed a statistically significant increase in colorectal cancer screening awareness and knowledge among participants. Colorectal cancer screening rates with FOBT increased from 51.0% to 80%. There was also a statistically significant increase in social engagement, that is, the intent to speak to friends and relatives about colorectal cancer screening.Conclusions: Findings indicate that culturally tailored colorectal cancer education facilitated by promotores in a rural environment, coupled with free stool-based test for colorectal cancer screening, is an effective way to increase colorectal cancer screening awareness, knowledge, and screening among Hispanics living in a rural area in Washington State. Impact: Culturally tailored home health interventions have the potential to achieve Healthy People 2020 colorectal cancer screening goals in Hispanic rural communities.
