Promoting colorectal cancer screening: A scoping review of screening interventions and resources

Community Collaboration to Advance Racial/Ethnic Equity in Colorectal Cancer Screening: Protocol for a Multilevel Intervention to Improve Screening and Follow-up in Community Health Centers

INTRODUCTION

Colorectal cancer (CRC) screening utilization is low among low-income, uninsured, and minority populations that receive care in community health centers (CHCs). There is a need for evidence-based interventions to increase screening and follow-up care in these settings.

METHODS

A multilevel, multi-component pragmatic cluster randomized controlled trial is being conducted at 8 CHCs in two metropolitan areas (Boston and Los Angeles), with two arms: (1) Mailed FIT outreach with text reminders, and (2) Mailed FIT-DNA with patient support. We also include an additional CHC in Rapid City (South Dakota) that follows a parallel protocol for FIT-DNA but is not randomized due to lack of a comparison group. Eligible individuals in participating clinics are primary care patients ages 45-75, at average-risk for CRC, and overdue for CRC screening. Participants with abnormal screening results are offered navigation for follow-up colonoscopy and CRC risk assessment.

RESULTS

The primary outcome is the completion rate of CRC screening at 90 days. Secondary outcomes include the screening completion rate at 180 days and the rate of colonoscopy completion within 6 months among participants with an abnormal result. Additional goals are to enhance our understanding of facilitators and barriers to CRC risk assessment in CHC settings.

CONCLUSIONS

This study assesses the effectiveness of two multilevel interventions to increase screening participation and follow-up after abnormal screening in under-resourced clinical settings, informing future efforts to address CRC disparities.

Leveraging Multi-Sectoral Partnership for Colorectal Cancer Education and Screening in the African American Community: A Protocol and Preliminary Results

Colorectal cancer (CRC) awareness and screening rates are still low in African Americans (AAs), especially for those who do not have regular access to health care. We established a multi-sector community partnership between academia, health system, cancer advocacy, and local county treasurer's office (CTO), to test a pilot CRC screening intervention using a tailored educational brochure and fecal immunochemical test (FIT). Participants were recruited at a local CTO in an urban midwestern region. Once eligible, participants were assigned to 2-by-2 intervention arms by educational strategy (brochure vs. no brochure) and FIT provision strategy (direct provision by onsite staff vs. indirect provision via phone/online request). We compared the effect of different strategies on FIT return rates. Of 1500 individuals approached, 212 were eligible for the study. The final sample consisted of 209 participants who were predominantly men (57%) and AAs (85%). No differences were found in the return rates by educational brochure (24% [brochure] vs. 23% [no brochure]; p = 0.82). In regard to FIT provision strategy, direct FIT provision yielded higher return rates than indirect provision (31% vs. 15%; p = 0.01). When the four groups were compared, direct provision with education brochure yielded the highest return rates (33.9%), followed by direct provision only (27.5%), indirect provision only (18%), and indirect provision with a brochure (12.2%). For community-based CRC screening intervention using stool-based test, the direct provision of FIT kits with educational brochure outperforms the other three strategies.

Screening of colorectal cancer: Methods and strategies

Colorectal cancer (CRC) has high incidence and mortality rates, and the emergence and application of CRC screening have helped us effectively control the occurrence and development of CRC. Currently, common international screening methods include tests based on feces and blood, and examination methods that allow for visualization, such as sigmoidoscopy and colonoscopy. Some methods have been widely used, whereas others such as multi-target stool RNA test are still being explored and developed, and are expected to become front-line screening methods for CRC in the future. The choice of screening method is affected by external conditions and the patients' situation, and the clinician must choose an appropriate strategy according to the actual situation and the patient's wishes. This article introduces various CRC screening methods and analyzes the factors relevant to the screening strategy.

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.

Comparative effectiveness of two interventions to increase colorectal cancer screening among females living in the rural Midwest

PURPOSE

To assess the comparative effectiveness of a tailored, interactive digital video disc (DVD) intervention versus DVD plus patient navigation (PN) intervention versus usual care (UC) on the uptake of colorectal cancer (CRC) screening among females living in Midwest rural areas.

METHODS

As part of a larger study, 663 females (ages 50-74) living in rural Indiana and Ohio and not up-to-date (UTD) with CRC screening at baseline were randomized to one of three study groups. Demographics , health status/history, and beliefs and attitudes about CRC screening were measured at baseline. CRC screening was assessed at baseline and 12 months from medical records and self-report. Multivariable logistic regression was used to determine whether females in each group were UTD for screening and which test they completed.

RESULTS

Adjusted for covariates, females in the DVD plus PN group were 3.5× more likely to complete CRC screening than those in the UC group (odds ratio [OR] 3.62; 95% confidence interval [CI]: 2.09, 6.47) and baseline intention to receive CRC screening (OR 3.45, CI: 2.21,5.42) at baseline. Adjusting for covariates, there was no difference by study arm whether females who became UTD for CRC screening chose to complete a colonoscopy or fecal occult blood test/fecal immunochemical test.

CONCLUSIONS

Many females living in the rural Midwest are not UTD for CRC screening. A tailored intervention that included an educational DVD and PN improved knowledge, addressed screening barriers, provided information about screening test options, and provided support was more effective than UC and DVD-only to increase adherence to recommended CRC screening.

Are behavioral economics interventions effective in increasing colorectal cancer screening uptake: A systematic review of evidence and meta-analysis?

Various interventions have been investigated to improve the uptake of colorectal cancer screening. In this paper, the authors have attempted to provide a pooled estimate of the effect size of the BE interventions running a systematic review based meta-analysis. In this study, all the published literatures between 2000 and 2022 have been reviewed. Searches were performed in PubMed, Scopus and Cochrane databases. The main outcome was the demanding the one of the colorectal cancer screening tests. The quality assessment was done by two people so that each person evaluated the studies separately and independently based on the individual participant data the modified Jadad scale. Pooled effect size (odds ratio) was estimated using random effects model at 95% confidence interval. Galbraith, Forrest and Funnel plots were used in data analysis. Publication bias was also investigated through Egger's test. All the analysis was done in STATA 15. From the initial 1966 records, 38 were included in the final analysis in which 72612 cases and 71493 controls have been studied. About 72% have been conducted in the USA. The heterogeneity of the studies was high based on the variation in OR (I2 = 94.6%, heterogeneity X2 = 670.01 (d.f. = 36), p < 0.01). The random effect pooled odds ratio (POR) of behavioral economics (BE) interventions was calculated as 1.26 (95% CI: 1.26 to 1.43). The bias coefficient is noteworthy (3.15) and statistically significant (p< 0.01). According to the results of this meta-analysis, health policy and decision makers can improve the efficiency and cost effectiveness of policies to control this type of cancer by using various behavioral economics interventions. It's noteworthy that due to the impossibility of categorizing behavioral economics interventions; we could not perform by group analysis.

Examining the Sustainability of Core Capacity and Evidence-Based Interventions for FIT-Based CRC Screening: California Colorectal Cancer Control Program

OBJECTIVES

We examined the extent to which funded satellite clinics could sustain the California Colon Cancer Control Program (C4P) strategies implemented in health systems to increase uptake of the fecal immunochemical test (FIT) or immunochemical fecal occult blood test (iFOBT) for colorectal cancer (CRC) screening in the absence of future C4P funds.

INTRODUCTION

Seven health systems consisting of 38 satellite clinics participated in C4P to examine the sustainability of the program in the absence future Centers for Disease Control and Prevention (CDC) funding.

METHODS

Quantitative and qualitative methods with a close and open-ended survey approach, and a prospective cohort design were used to examine the sustainability of the C4P in health systems.

RESULTS

A total of 61% of satellite clinics could not sustain funding stability. Only 26% could sustain funding stability. About, 71%, 26%, and 21% of the satellite clinics could sustain the small media platform, patient navigation services, and community health workers (CHWs), respectively. All the satellite clinics sustained the provider reminder system and professional development. Roughly, 71% and 42% of funded satellite clinics could not sustain the patient navigators and CHWs, respectively. The satellite clinics that could sustain funding stability, sustained patient navigation services and CHWs. Health systems that could not sustain funding stability, could not sustain patient navigation services and CHWs. Qualitatively, the need to support uninsured priority populations, health educators, patient navigators, care coordination activities, outreach services, and provision of enhanced services emerged. The need to support enhanced quality measures, expansion of funding, Medi-Cal Public Hospital Redesign and Incentive coverage, health plan, community linkages, resource sharing, and best practices specifically on CRC screening emerged. Themes such as automated reminder, limited personalized care delivery and capacity, transportation barriers, staff salary, expansion of care through patient navigation, and culturally appropriate media campaign also emerged.

CONCLUSION

Overall, to address sustainability barriers, funding stability should be maintained in the health systems.

"It's Probably Just Hemorrhoids": A Qualitative Exploration of the Lived Experiences and Perceptions of Long-term Survivors of Early-Onset Colorectal Cancer

BACKGROUND

Colorectal cancer among adults aged <50 years [early-onset colorectal cancer (EOCRC)] is projected to be the leading cause of cancer-related death by 2030. Although evidence-based guidelines for colorectal cancer screening now recommend beginning screening at age 45, the needs of many at-risk young adults are potentially being overlooked. Unanswered questions also remain regarding the effects of EOCRC on quality-of-life and psychosocial outcomes. This qualitative study explored the lived experiences and perceptions of a sample of adult EOCRC survivors in the United States through one-on-one interviews.

METHODS

An EOCRC advocate survivor team member led 27 structured virtual interviews using a 10-question interview guide. Data were analyzed using a 9-step inductive approach.

RESULTS

Participants were geographically diverse. Most were women (66.6%) who self-identified as non-Hispanic White (85.2%). The mean age at interview was 40.19 ± 5.99; at diagnosis, 33.93 ± 5.90. Six overarching themes emerged: signs and symptoms, risk factors, system-level factors, quality of life, social support, and reflection.

CONCLUSIONS

The specific needs of individuals in this younger population of patients with colorectal cancer should be considered during treatment and future interventions and throughout survivorship.

IMPACT

While the reasons for the increasing incidence of EOCRC are currently unknown, the lived experiences and perceptions of EOCRC survivors noted in this study highlight specific needs of this population that can inform educational materials, comprehensive care, future research, and policy change.

Barriers and facilitators of colorectal cancer screening using the 5As framework: A systematic review of US studies

Despite clear evidence that regular screening reduces colorectal cancer (CRC) mortality and the availability of multiple effective screening options, CRC screening continues to be underutilized in the US. A systematic literature search of four databases - Ovid, Medline, EBSCHOhost, and Web of Science - was conducted to identify US studies published after 2017 that reported on barriers and facilitators to CRC screening adherence. Articles were extracted to categorize relevant CRC screening barriers or facilitators that were assessed against CRC screening outcomes using the 5As dimensions: Access, Affordability, Acceptance, Awareness, Activation. Sixty-one studies were included. Fifty determinants of screening within the 5As framework and two additional dimensions including Sociodemographics and Health Status were identified. The Sociodemographics, Access, and Affordability dimensions had the greatest number of studies included. The most common factor in the Access dimension was contact with healthcare systems, within the Affordability dimension was insurance, within the Awareness dimension was knowledge CRC screening, within the Acceptance dimension was health beliefs, within the Activation dimension was prompts and reminders, within the Sociodemographics dimension was race/ethnicity, and among the Health Status dimension was chronic disease history. Among all studies, contact with healthcare systems, insurance, race/ethnicity, age, and education were the most common factors identified. CRC screening barriers and facilitators were identified across individual, clinical, and sociocontextual levels. Interventions that consider multilevel strategies will most effectively increase CRC screening adherence.

Using the Multi-Theory Model (MTM) of Health Behavior Change to Explain the Seeking of Stool-Based Tests for Colorectal Cancer Screening

Colorectal cancer is the third most common cancer worldwide and is the second leading cause of cancer-associated deaths. While colorectal cancer is on the decline in the United States (US), disparities still exist, despite the non-invasive screening modalities, such as stool-based tests have shown themselves to be effective in the detection of colorectal cancer. Many of the existing stool-based test interventions lack the use of a contemporary theory-based approach. Given the paucity of theory-based interventions intended to promote stool-based tests, this cross-sectional study utilizes the multi-theory model (MTM) of health behavior change to explain the seeking of stool-based tests for colorectal cancer (CRC) screening. An online 57-item questionnaire with an established psychometric validity was used to collect responses from the US-based sample (n = 640) of adults aged 45-75 years old. The data were analyzed using bivariate and multivariate statistical methods. Structural equation modeling (SEM) was conducted to test the construct validity of the survey instrument. In this nationwide sample, 39.2% (n = 251) of participants reported having received some form of a stool-based test. Among the participants who did not undergo stool-based CRC screening, the MTM subscales, including "participatory dialogue", "behavioral confidence", and "changes in the social environment", were significant predictors of initiating screening behavior and explained 48% of the variance in the initiation among this group (R2 = 0.579, F = 5.916, p < 0.001; adjusted R2 = 0.481). The MTM may be a useful framework with which to design educational, mass media, social media, and clinical interventions for the promotion of stool-based CRC screening among adults aged 45-75 years old.

Factors influencing organised faecal occult blood test screening participation in culturally and linguistically diverse populations: a scoping review

OBJECTIVE

This review aims to provide a comprehensive overview of the literature examining factors influencing participation in organised faecal occult blood test (FOBT) screening programmes in culturally and linguistically diverse populations. This article addresses gaps in the literature by providing a mixed methods review of the multilevel influences on FOBT screening in culturally and linguistically diverse (CALD) populations. This review was guided by the question "What are the factors influencing participation in organised FOBT screening programs in CALD populations?"

STUDY DESIGN

Scoping review.

METHODS

A scoping review methodology was used to summarise the available evidence. A thematic analysis of the included studies was undertaken to identify factors influencing organised FOBT screening participation in CALD populations from the literature.

RESULTS

FOBT screening participation was lower by ethnicity, religion, birthplace and language spoken. Barriers to screening included, faecal aversion, fatalism, fear of cancer, language and literacy barriers, difficulty accessing translated materials and low colorectal screening knowledge and awareness. CALD populations also had lower perceived benefits, susceptibility and cues to action, higher perceived barriers and greater perceived external health locus control than non-CALD populations. Facilitators of screening included positive attitudes to screening, general practitioner recommendations and social support. Group education sessions and narrative-based screening information were found to increase screening participation.

CONCLUSION

This review highlights the range of interrelated factors influencing participation in organised FOBT screening programmes in CALD populations and proposes multicomponent interventions to address low screening uptake. Features of successful community-level interventions should be explored further. Narratives show promise for engaging CALD populations. Accessibility of screening information should be addressed at the system level. Leveraging the general practitioner relationship in promoting FOBT screening programmes may also be an effective strategy to target 'hard-to-reach' populations.

Application and development of noninvasive biomarkers for colorectal cancer screening: a systematic review

BACKGROUND

Colorectal cancer (CRC) is the second most common cause of cancer-related death (9.4% of the 9.9 million cancer deaths). However, CRC develops slowly, and early detection and intervention can effectively improve the survival rate and quality of life. Although colonoscopy can detect and diagnose CRC, it is unsuitable for CRC screening in average-risk populations. Some commercial kits based on DNA mutation or methylation are approved for screening, but the low sensitivity for advanced adenoma or early-stage CRC would limit the applications.

MAIN RESULTS

Recently, researchers have focused on developing noninvasive or minimally invasive, easily accessible biomarkers with higher sensitivity and accuracy for CRC screening. Numerous reports describe advances in biomarkers, including DNA mutations and methylation, mRNA and miRNA, gut microbes, and metabolites, as well as low-throughput multiomics panels. In small cohorts, the specificity and sensitivity improved when fecal immunochemical testing combined with other biomarkers; further verification in large cohorts is expected. In addition, the continuous improvement of laboratory technology has also improved the sensitivity of detection technology, such as PCR, and the application of CRISPR/Cas technology. Besides, artificial intelligence has extensively promoted the mining of biomarkers. Machine learning was performed to construct a diagnosis model for CRC screening based on the cfDNA fragment features from whole-genome sequencing data. In another study, multiomics markers, including cfDNA, epigenetic, and protein signals, were also discovered by machine learning. Finally, advancements in sensor technology promote the applicability of volatile organic compounds in CRC early detection.

CONCLUSION

Here, the authors review advances in early detection and screening of CRC based on different biomarker types. Most studies reported optimistic findings based on preliminary research, and prospective clinical studies are ongoing. These promising biomarkers are expected to more accurately identify early-stage patients with CRC and be applied in the future.

American Cancer Society's report on the status of cancer disparities in the United States, 2021

In this report, the authors provide comprehensive and up-to-date US data on disparities in cancer occurrence, major risk factors, and access to and utilization of preventive measures and screening by sociodemographic characteristics. They also review programs and resources that have reduced cancer disparities and provide policy recommendations to further mitigate these inequalities. The overall cancer death rate is 19% higher among Black males than among White males. Black females also have a 12% higher overall cancer death rate than their White counterparts despite having an 8% lower incidence rate. There are also substantial variations in death rates for specific cancer types and in stage at diagnosis, survival, exposure to risk factors, and receipt of preventive measures and screening by race/ethnicity, socioeconomic status, and geographic location. For example, kidney cancer death rates by sex among American Indian/Alaska Native people are ≥64% higher than the corresponding rates in each of the other racial/ethnic groups, and the 5-year relative survival for all cancers combined is 14% lower among residents of poorer counties than among residents of more affluent counties. Broad and equitable implementation of evidence-based interventions, such as increasing health insurance coverage through Medicaid expansion or other initiatives, could substantially reduce cancer disparities. However, progress will require not only equitable local, state, and federal policies but also broad interdisciplinary engagement to elevate and address fundamental social inequities and longstanding systemic racism.

Adaptation of colorectal cancer screening tailored navigation content for American Indian communities and early results using the intervention

BACKGROUND

American Indians (AI) experience major colorectal cancer (CRC) screening disparities with commensurate inequity in CRC mortality and other outcomes. The purpose of this report is to describe the methods and early results of adapting a previously successful intervention for the AI community.

METHODS

The educational content and delivery strategy of the parent intervention were adapted for AIs guided by an adaptation framework and cultural consultations with the community and clinicians. As part of the environmental scanning, we identified the need to substantively revise our data entry, collection, and tracking system and develop a REDCap database for this purpose. In this study, we staggered the implementation of the intervention in each facility to inform the process from one clinic to the next, and assess both the clinical outcomes of the tailored intervention and the implementation processes across two clinic settings, Facilities A and B.

RESULTS

The REDCap database is an indispensable asset, and without it we would not have been able to obtain reliable aggregate screening data while improvements to facility electronic health records are in progress. Approximately 8% (n = 678) of screening-eligible patients have been exposed to the navigator intervention. Of those exposed to the navigator intervention, 37% completed screening.

CONCLUSIONS

With the small numbers of patients exposed so far to the intervention, it would be premature to draw any broad conclusions yet about intervention effects. However, early screening completion rates are substantial advances on existing rates, and we have demonstrated that a tailored navigator intervention for facilitating CRC screening was readily adapted with provider and community input for application to AIs. A REDCap database for tracking of CRC screening by navigators using tablets or laptops on- or offline is easy to use and allows for generation of aggregate, anonymized screening data.

TRIAL REGISTRATION

There was no health intervention meeting the criteria of a clinical trial. The University of Arizona Institutional Review Board granted exemption from obtaining informed consent from patients undergoing CRC screening after administration of the tailored navigation intervention as usual care.

Adaptation of a Community Health Advisor Intervention to Increase Colorectal Cancer Screening Among African Americans in the Southern United States

Community health advisor (CHA) interventions increase colorectal cancer (CRC) screening rates. African Americans experience CRC disparities in incidence and mortality rates compared to whites in the US. Focus groups and learner verification were used to adapt National Cancer Institute CRC screening educational materials for delivery by a CHA to African American community health center patients. Such academic-community collaboration improves adoption of evidence-based interventions. This short article describes the adaptation of an evidence-based cancer education intervention for implementation in an African American community.
