A community-based trial of educational interventions with fecal immunochemical tests for colorectal cancer screening uptake among blacks in community settings

Longitudinal adherence to annual colorectal cancer screening among Black persons living in the United States enrolled in a community-based randomized trial

BACKGROUND

This study examined repeat colorectal cancer screening rates at 12 and 24 months as part of a randomized intervention trial among Black persons living in the United States and factors associated with screening adherence.

METHODS

Participants completed a survey assessing demographics and Preventive Health Model (PHM) factors (e.g., self efficacy, susceptibility) and received either a culturally targeted photonovella plus free fecal immunochemical test (FIT) kits (intervention group) or a standard educational brochure plus free FIT kits (comparison group). FIT return was assessed at 6, 12, and 24 months. Descriptive statistics summarized patterns of repeat screening. Logistic regression models assessed FIT uptake overtime, and demographic and PHM factors associated with screening adherence.

RESULTS

Participants (N = 330) were U.S.-born (93%), non-Hispanic (97%), and male (52%). Initial FIT uptake within 6 months of enrollment was 86.6%, and subsequently dropped to 54.5% at 12 months and 36.6% at 24 months. Higher FIT return rates were observed for the brochure group at 24 months (51.5% vs 33.3% photonovella, p = .023). Multiple patterns of FIT kit return were observed: 37% completed FIT at all three time points (full adherence), 22% completed two of three (partial adherence), 29% completed one of three (partial adherence), and 12% did not return any FIT kits (complete nonadherence). Predictors of full adherence were higher levels of education and self-efficacy.

CONCLUSIONS

Full adherence to repeat screening was suboptimal. Most participants had partial adherence (one or two of three) to annual FIT screening. Future studies should focus on strategies to support repeat FIT screening.

Cardiovascular Health and Colorectal Cancer Screening in Black Men: A Cross-Sectional Analysis

African American/Black (henceforth Black) men face disproportionate risks of morbidity and mortality from both cardiovascular disease (CVD) and colorectal cancer (CRC). The American Heart Association's Life's Simple 7 (LS7) tool was designed to examine predictors of CVD with included behaviors also linked to CRC risk (i.e., smoking status, weight, diet, and physical activity). However, no studies have combined LS7 assessment alongside CRC screening history, which serves as a proxy for assessing CRC risk, in Black men. In this study, Black men aged 45-75 participating in annual community wellness events were screened for 6 of 7 LS7 measures (excluding diet, LS6) and self-reported CRC screening. Analyses conducted using R 4.0.5. revealed that Black men (N = 680), with an average age of 57.3 years (SD = 7.5), reported poor (39.7%), intermediate (34.6%), or ideal (25.7%) LS6 scores with higher scores corresponding to lower risk for CVD. However, for every 1-point increase in LS6 scores (0-6), there was a 26% lower odds of reported CRC screening (p = .001). In the fully adjusted model, men with 4+ ideal LS6 behaviors had a 60% lower odds of self-reported CRC screening compared to those with two ideal LS6 behaviors (p < .001). These findings underscore the need for culturally relevant interventions for Black men across all levels of cardiovascular health (CVH) to increase CRC screening uptake.

Factors associated with prior completion of colorectal cancer and hepatitis C virus screenings among community health center patients: a cross-sectional study to inform a multi-behavioral educational intervention

BACKGROUND

Colorectal cancer (CRC) and liver cancer are two of the leading causes of cancer death in the United States and persistent disparities in CRC and liver cancer incidence and outcomes exist. Chronic hepatitis C virus (HCV) infection is one of the main contributors to liver cancer. Effective screening for both CRC and HCV exist and are recommended for individuals based upon age, regardless of gender or sex assigned at birth. Recommendations for both screening behaviors have been recently updated. However, screening rates for both CRC and HCV are suboptimal. Targeting adoption of multiple screening behaviors has the potential to reduce cancer mortality and disparities.

OBJECTIVE

To examine psychosocial factors associated with completion of CRC and HCV screenings in order to inform a multi-behavioral educational intervention that pairs CRC and HCV screening information.

METHODS

A cross-sectional survey was conducted with participants (N = 50) recruited at two community health centers in Florida (United States). Kruskal-Wallis and Fisher's exact tests were used to examine associations between completion of both CRC and HCV screening, CRC and HCV knowledge, Preventive Health Model constructs (e.g., salience and coherence, response efficacy, social influence), and sociodemographic variables.

RESULTS

Most participants were White (84%), female (56%), insured (80%), and reported a household income of $25,000 or less (53%). 30% reported ever previously completing both CRC and HCV screenings. Prior completion of both screening behaviors was associated with higher educational attainment (p = .014), having health insurance (p = .022), being U.S.-born (p = .043), and higher salience and coherence scores for CRC (p = .040) and HCV (p = .004).

CONCLUSIONS

Findings demonstrate limited uptake of both CRC and HCV screenings among adults born between 1945 and 1965. Uptake was associated with multiple sociodemographic factors and health beliefs related to salience and coherence. Salience and coherence are modifiable factors associated with completion of both screening tests, suggesting the importance of incorporating these health beliefs in a multi-behavioral cancer education intervention. Additionally, health providers could simultaneously recommend and order CRC and HCV screening to improve uptake among this age cohort.

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.

Effective strategies for Fecal Immunochemical Tests (FIT) programs to improve colorectal cancer screening uptake among populations with limited access to the healthcare system: a rapid review

BACKGROUND

Colorectal cancer (CRC) is one of the leading causes of cancer death globally. CRC screening can reduce the incidence and mortality of CRC. However, socially disadvantaged groups may disproportionately benefit less from screening programs due to their limited access to healthcare. This poor access to healthcare services is further aggravated by intersecting, cumulative social factors associated with their sociocultural background and living conditions. This rapid review systematically reviewed and synthesized evidence on the effectiveness of Fecal Immunochemical Test (FIT) programs in increasing CRC screening in populations who do not have a regular healthcare provider or who have limited healthcare system access.

METHODS

We used three databases: Ovid MEDLINE, Embase, and EBSCOhost CINAHL. We searched for systematic reviews, meta-analysis, and quantitative and mixed-methods studies focusing on effectiveness of FIT programs (request or receipt of FIT kit, completion rates of FIT screening, and participation rates in follow-up colonoscopy after FIT positive results). For evidence synthesis, deductive and inductive thematic analysis was conducted. The findings were also classified using the Cochrane Methods Equity PROGRESS-PLUS framework. The quality of the included studies was assessed.

RESULTS

Findings from the 25 included primary studies were organized into three intervention design-focused themes. Delivery of culturally-tailored programs (e.g., use of language and interpretive services) were effective in increasing CRC screening. Regarding the method of delivery for FIT, specific strategies combined with mail-out programs (e.g., motivational screening letter) or in-person delivery (e.g., demonstration of FIT specimen collection procedure) enhanced the success of FIT programs. The follow-up reminder theme (e.g., spaced out and live reminders) were generally effective. Additionally, we found evidence of the social determinants of health affecting FIT uptake (e.g., place of residence, race/ethnicity/culture/language, gender and/or sex).

CONCLUSIONS

Findings from this rapid review suggest multicomponent interventions combined with tailored strategies addressing the diverse, unique needs and priorities of the population with no regular healthcare provider or limited access to the healthcare system may be more effective in increasing FIT screening. Decision-makers and practitioners should consider equity and social factors when developing resources and coordinating efforts in the delivery and implementation of FIT screening strategies.

Understanding perceptions of the public and key stakeholders toward a localised cancer screening promotion campaign

The aim of this study was to explore perceptions of members of the public and key stakeholders of a localised campaign to increase engagement with cervical cancer screening. Whilst numerous interventions have been trialled to increase engagement with cancer screening, the evidence for their effectiveness is somewhat mixed. In addition, few studies have explored the perceptions of members of the public targeted by such campaigns nor the perceptions of healthcare professionals who may be involved in delivering such campaigns in the United Kingdom. Members of the public who had potentially been exposed to the campaign in the North-East of England were approached to take part in individual interviews whilst stakeholders were invited to take part in a focus group. A total of 25 participants (13 members of the public, 12 stakeholders) took part. All interviews were audio recorded, transcribed verbatim and analysed using applied thematic analysis. Four themes were identified, two of which were cross-cutting (barriers to screening and factors promoting screening), with one theme identified as specific to the public interviews (knowledge of and attitudes toward awareness campaigns) and one theme specific to the focus group (keeping campaigns relevant. Awareness of the localised campaign was limited; however, when made aware, participants were mostly positive towards the approach, although mixed responses were noted in relation to financial incentives. Members of the public and stakeholders identified some common barriers to screening although differed in their perceptions of promotional factors. This study highlights the importance of multiple strategies to promote cervical screening as one size fits all approach may limit engagement.

Colorectal Cancer Screening Pilot Project in Tehran-Iran, a Feasibility Study

BACKGROUND

Colorectal cancer (CRC) is the third most common cancer in Iran, where there is no organised CRC-screening programme. This study aimed to evaluate feasibility of CRC screening using a qualitative fecal immunochemical test (FIT) among Iranian average-risk adults.

METHODS

In this feasibility study, 7039 individuals aged 50-75 years were invited by community health workers (CHWs) in southern Tehran and its suburban districts between April 2018 and November 2019. The CHWs performed a qualitative FIT with cut-off level 50 ng Hb/mL buffer and referred those with positive-FIT for colonoscopy to the endoscopy center of Shariati hospital in Tehran. Outcomes included acceptance rate, FIT positivity rate, colonoscopy compliance, detection rates and positive predictive values (PPVs) with 95% confidence interval for CRC and advanced adenomas (AAs).

RESULTS

Acceptance rate at initial invitation was 71.7%. From 4974 average-risk adults (1600 males and 3374 females) who were offered FIT, 96.8% (n=4813) provided valid samples, of whom 471 (9.8%) tested positive. Among FIT-positive participants, 150 (31.8%) underwent colonoscopy; CRC was detected in 2.0% (n=3) and adenomas in 27.3% (n=41). Detection rate of CRC and AAs per 1000-FIT-screened participants was 0.6 (0.1-1.8) [males: 0.7 (0.01-3.6), females: 0.6 (0.07-2.0)] and 4.2 (2.5-6.4) [males: 5.9 (2.6-11.0), females: 3.4 (1.7-6.0)], respectively. PPVs were 2.0% (0.4-5.7) for CRC and 13.3% (8.3-19.8) for AAs. There was no association between gender and the studied outcomes.

CONCLUSION

Our results partially support the feasibility of scaling up organized CRC-screening through the existing healthcare system in Iran; it remains to be discussed carefully to ensure the capacity of healthcare system for adequate colonoscopy services.

Interventions to reduce cancer screening inequities: the perspective and role of patients, advocacy groups, and empowerment organizations

BACKGROUND

Health inequities lead to low rates of cancer screening in certain populations, such as low-income and ethnic minority groups. Different interventions to address this have been developed with mixed results. However, interventions are not always developed in collaboration with the people they target. The aim of our article is to present the viewpoint of patients, survivors, advocates, and lay persons on interventions to increase cancer screening from a health inequity perspective.

METHODS

We prepared talking points to guide discussions between coauthors, who included representatives from nine patient and survivor advocacy groups, organizations working for citizen/patient empowerment, and health equity experts. Perspectives and opinions were first collected through video conferencing meetings and a first draft of the paper was prepared. All authors, read through, revised, and discussed the contents to reach an agreement on the final perspectives to be presented.

RESULTS

Several themes were identified: it is important to not view screening as a discrete event; barriers underlying an individual's access and willingness to undergo screening span across a continuum; individually tailored interventions are likely to be more effective than a one-size fits-all approach because they may better accommodate the person's personal beliefs, knowledge, behaviors, and preferences; targeting people who are unknown to medical services and largely unreachable is a major challenge; including professional patient advocacy groups and relevant lay persons in the cocreation of interventions at all stages of design, implementation, and evaluation is essential along with relevant stakeholders (healthcare professionals, researchers, local government and community organizations etc).

CONCLUSIONS

Interventions to address cancer screening inequity currently do not adequately solve the issue, especially from the viewpoint of patients, survivors, and lay persons. Several core pathways should be focused on when designing and implementing interventions: advancing individually tailored interventions; digital tools and social media; peer-based approaches; empowerment; addressing policy and system barriers; better design of interventions; and collaboration, including the involvement of patients and patient advocacy organizations.

A multilevel, low literacy dual language intervention to promote colorectal cancer screening in community clinics in Florida: A randomized controlled trial

One of the largest disparities in cancer mortality in the United States occurs with colorectal cancer (CRC). The objectives of this multilevel two-arm intervention trial were to compare the efficacy of two interventions to promote CRC screening (CRCS) with fecal immunochemical test (FIT) and examine sociodemographic and psychosocial predictors of FIT screening. Individuals ages 50-75 (n = 326) who were not up-to-date with CRCS, could understand English or Spanish, and were at average CRC risk were recruited from two federally qualified health centers (FQHCs) in Florida. Prior to intervention, CRCS rates in the FQHCs were 27.1% and 32.9%, respectively. Study enrollment occurred April 2018-November 2019. System-level intervention components included leveraging electronic medical record (EMR) systems and delivering patient reminders. Participants were randomized to C-CARES (education+FIT) or C-CARES Plus (C-CARES+personalized coaching [for those not completing FIT within 90 days]). Primary outcome was completed FIT returned <1 year. Primary outcome analyses were performed using logistic regression. 225 participants completed FIT (69.0% [95% CI: 64.0-74.0%]), with no significant difference in FIT uptake by intervention arm (67.3% C-CARES Plus vs. 70.8% C-CARES; p = .49). FIT uptake was significantly higher among patients who received intervention materials in Spanish (77.2%) compared to those who received materials in English (63.2%, p < .01). The personalized coaching in the C-CARES Plus arm did not appear to provide added benefit beyond the C-CARES intervention. Multilevel approaches that include EMR prompts, reminders, FIT access, and provision of low-literacy, language-concordant education can support efforts to improved community clinics' CRCS rates. Future efforts should focus on repeat FIT screening. Trial registration: The trial was registered at ClinicalTrials.gov (NCT03906110).

Online health information seeking and eHealth literacy among Spanish language- dominant Latinos receiving care in a community clinic (Preprint)

Background

eHealth literacy is the ability to seek, obtain, and decipher online health information (OHI) for health and disease management. Rapid developments in eHealth (eg, health care services and online information) place increased demands on patients to have high eHealth literacy levels. Yet, greater emphasis on eHealth may disproportionately affect groups with limited eHealth literacy. Cultural background, language, and eHealth literacy are influential considerations affecting health care and information access, health care use, and successful eHealth resource use, and they may influence OHI seeking for behavioral change toward cancer prevention.

Objective

This study aimed to characterize the extent of OHI seeking and eHealth literacy among Spanish-dominant (SD) Latino adults aged 50 to 75 years. Further, we aimed to examine potential associations between sociodemographic characteristics, Preventive Health Model (PHM) constructs, OHI-seeking behaviors, and eHealth literacy, separately.

Methods

Participants (N=76) self-identified as Latino, were enrolled in a colorectal cancer (CRC) screening intervention, were aged 50 to 75 years, were at average risk for CRC, were not up to date with CRC screening, and preferred receiving health information in Spanish. We describe participants’ sociodemographic characteristics, PHM constructs, OHI-seeking behaviors, and eHealth literacy—among those seeking OHI—assessed at enrollment. Descriptive analyses were first performed for all variables. Next, primary univariate logistic analyses explored possible associations with OHI seeking. Finally, using data from those seeking OHI, exploratory univariate analyses sought possible associations with eHealth literacy.

Results

A majority (51/76, 67%) of the participants were female, 62% (47/76) reported not having graduated high school, and 41% (31/76) reported being unemployed or having an annual income of less than US $10,000. Additionally, 75% (57/76) of the participants reported not having health insurance. In total, 71% (54/76) of the participants reported not having sought OHI for themselves or others. Univariate logistic regression suggested that higher educational attainment was significantly associated with an increased likelihood of having sought OHI (odds ratio 17.4, 95% CI 2.0-150.7; P=.009). Among those seeking OHI (22/76, 29%), 27% (6/22) were at risk of having low eHealth literacy based on an eHealth Literacy Scale score of less than 26. Among OHI seekers (22/76, 29%), an examination of associations found that higher eHealth literacy was associated with greater self-efficacy for screening with the fecal immunochemical test (β=1.20, 95% CI 0.14-2.26; P=.02).

Conclusions

Most SD Latino participants had not sought OHI for themselves or others (eg, family or friends), thus potentially limiting access to beneficial online resources. Preliminary findings convey that higher eHealth literacy occurs among those with higher self-efficacy for CRC screening. Findings inform areas of focus for future larger-scale investigations, including further exploration of reasons for not seeking OHI among SD Latino adults and an in-depth look at eHealth literacy and cancer screening behaviors.

A Review of Cancer Screening Recommendations during the COVID-19 Pandemic

BACKGROUND

Cancer screening tests are recommended to prevent cancer-associated mortality by detecting precancerous and cancerous lesions in early stages. The COVID-19 pandemic disrupted the utilization of preventive health care services. While there was a rise in the number of cancer screening tests beginning in late 2020, screenings remained 29%-36% lower than in the pre-pandemic era.

OBJECTIVE

The objective of this review article was to assist health care providers in identifying approaches for prioritizing patients and increasing breast, cervical, and colorectal cancer screening during the uncertainty of the COVID-19 pandemic.

METHODS

We used the scoping review framework to identify articles on PubMed and EBSCO databases. A total of 403 articles were identified, and 23 articles were selected for this review. Literature review ranged from January 1st, 2020 to September 30th, 2021.

RESULTS

The articles included two primary categories of recommendations: (1) risk stratification and triage to prioritize screenings and (2) alternative methods to conduct cancer screenings. Risk stratification and triage recommendations focused on prioritizing high-risk patients with an abnormal or suspicious result on the previous screening test, of certain age group and sex, having personal medical or family history of cancers, currently symptomatic, predisposed to hereditary cancers, and cancer-causing mutations. Other recommended strategies included: identifying areas facing most disparities, creating algorithms and using artificial intelligence to create cancer-risk scores, leveraging in-person visits to assess cancer risk, and providing the option of open access screenings where patients can schedule screenings and can be assigned a priority category by health care staff. Some recommended using telemedicine to categorize patients and determine screening-eligibility for patients with new complaints. Several articles noted the importance of implementing preventive measures such as COVID-19 screening prior to the procedures, maintaining hygiene measures, and social distancing in waiting rooms. Alternative screening methods which do not require an in-person clinic visit and can effectively screen patients for cancers included mailing self-collection sampling kits for cervical and colorectal cancers and implementing or expanding mobile screening units.

CONCLUSIONS

Although the COVID-19 pandemic had devastating effects on population health globally, it could be an opportunity to adapt and evolve cancer screening methods. Disruption often creates innovation, and focus on alternative methods for cancer screenings may help reach rural and under-resourced areas after the pandemic has ended.

Characterizing Health Literacy Among Spanish Language-Preferring Latinos Ages 50-75

BACKGROUND

Cultural background, language, and literacy are factors that may affect access, healthcare utilization, and cancer screening behaviors.

OBJECTIVE

This study aimed to characterize health literacy among Spanish-preferring Hispanic/Latino individuals ages 50-75 and examine associations between sociodemographic characteristics, health beliefs, and health literacy.

METHODS

Participants self-identified as Hispanic/Latino, preferring health information in Spanish, were ages 50-75 years old, at average risk for colorectal cancer (CRC), not up to date with CRC screening, and enrolled in a CRC screening education intervention trial. Sociodemographic characteristics, health beliefs, and health literacy (i.e., difficulty understanding written health information and confidence completing health forms) were assessed at baseline. Descriptive and logistic regression analyses were performed.

RESULTS

Fifty-three percent of participants reported either sometimes having difficulty or always having difficulty with written health information, and 25% reported always asking for help or being not so confident in completing health forms. Univariate predictors of adequate health literacy for written health information were lower cancer worry and lower religious beliefs. Higher educational attainment predicted confidence in completing health forms.

CONCLUSIONS

Findings highlight the need for interventions that address health beliefs and health literacy among Hispanic/Latino patients who have low confidence in completing written forms and difficulty understanding written information and reinforce the use of plain language and salient design features when developing patient education materials.

Systematic Review of Interventions to Increase Stool Blood Colorectal Cancer Screening in African Americans

African Americans experience colorectal cancer (CRC) related disparities compared to other racial groups in the United States. African Americans are frequently diagnosed with CRC at a later stage, screening is underutilized, and mortality rates are highest in this group. This systematic review focused on intervention studies using stool blood CRC screening among African Americans in primary care and community settings. Given wide accessibility, low cost, and ease of dissemination of stool-based CRC screening tests, this review aims to determine effective interventions to improve participation rates. This systematic review included intervention studies published between January 1, 2000 and March 16, 2019. After reviewing an initial search of 650 studies, 11 studies were eventually included in this review. The included studies were studies conducted in community and clinical settings, using both inreach and outreach strategies to increase CRC screening. For each study, an unadjusted odds ratio (OR) for the CRC screening intervention compared to the control arm was calculated based on the data in each study to report effectiveness. The eleven studies together recruited a total of 3334 participants. The five studies using two-arm experimental designs ranged in effectiveness with ORs ranging from 1.1 to 13.0 using interventions such as mailed reminders, patient navigation, and tailored educational materials. Effective strategies to increase stool blood testing included mailed stool blood tests augmented by patient navigation, tailored educational materials, and follow-up calls or mailings to increase trust in the patient-provider relationship. More studies are needed on stool blood testing interventions to determine effectiveness in this population.

Learner Verification: A Methodology to Create Suitable Education Materials

Background:

Learner verification and revision (LV&R) is a research methodological approach to inform educational message design with the aim of producing suitable, actionable, and literacy appropriate messages to aid in awareness, adoption of healthy behaviors, and decision-making. It consists of a series of participatory steps that engage users throughout materials development, revision, and refinement. This approach is congruent with Healthy People 2030 communication objectives to improve access to information among diverse, multicultural, multilingual populations, and enhance health care quality toward health equity.

Brief description of activity:

To illustrate LV&R, we describe its use in three cancer education projects that produced targeted information about (1) inherited breast cancer among African Americans (brochure); (2) colorectal cancer screening among Latinos (photo novella and DVD); and (3) smoking-relapse prevention among patients receiving cancer treatment (video). We discuss rationale for its application in the three exemplars and extrapolate lessons learned from our experiences when using this approach.

Implementation:

A qualitative approach entailing individual or group-based discussions helped to examine the elements of learner verification (i.e., attraction, comprehension, self-efficacy, cultural acceptability, persuasion). The following steps are reported: (1) preparation of materials, interview guide, and recruitment; (2) interviewing of participants; and (3) evaluation of responses. Data were analyzed by use of a coding system that placed participant responses from each of the elements into data summary matrices. Findings informed revisions and refinement of materials.

Results:

LV&R was effectively applied across the three cancer education projects to enhance the suitability of the materials. As a result, the materials were improved by using clearer, more salient language to enhance comprehension and cultural acceptability, by integrating design elements such as prompts, headers, and stylistic edits to reduce text density, incorporating preferred colors and graphics to improve aesthetic appeal, and including actionable terms and words to bolster motivation and self-efficacy.

Lessons learned:

Results suggest that LV&R methodology can improve suitability of education materials through systematic, iterative steps that engage diverse, multicultural, multilingual populations. This approach is a critical participa-tory strategy toward health equity, and is appropriate in a variety of education, research, and clinical practice settings to improve health communications. [HLRP: Health Literacy Research and Practice. 2021;5(1):e49–e59.]

Plain Language Summary:

This article describes the use of a systematic approach called “learner verification” used for developing educational materials. This approach involves obtaining feedback from audience members to ensure that the information is understandable, attractive in design, motivating, and culturally relevant.

Examining aspects of successful community-based programs promoting cancer screening uptake to reduce cancer health disparity: A systematic review

Certain minorities in the US are disproportionately burdened with higher cancer incidence and mortality rates. Programs encouraging timely uptake of cancer screening measures serve to reduce cancer health disparities. A systematic literature review was conducted to assess the effectiveness and the qualities of these programs, and to elucidate characteristics of success programs to aid in designing of future ones. We focused on community-based programs rather than clinic-based programs as the former are more likely to reach disadvantaged populations, and on prevention programs for breast, cervical, and/or colon cancers as longstanding screening recommendations for these cancers exist. PubMed, CINAHL and EBSCO databases were searched for articles that utilized community organizations and community health workers. Fourteen programs described in 34 manuscripts were identified. While 10 of 14 programs reported statistically significant increases in cancer prevention knowledge and/or increase in screening rates, only 7 of them enrolled large numbers of participants (defined as ≥1000). Only 7 programs had control groups, only 4 programs independently verified screening uptake, and 2 programs had long-term follow-up (defined as more than one screening cycle). Only one program demonstrated elimination of cancer health disparity at a population level. While most community-based cancer prevention programs have demonstrated efficacy in terms of increased knowledge and/or screening uptake, scalability and demonstration in reduction at a population level remain a challenge.

Interventions for increasing colorectal cancer screening uptake among African-American men: A systematic review and meta-analysis

BACKGROUND

African-American men have the lowest 5-year survival rate in the U.S. for colorectal cancer (CRC) of any racial group, which may partly stem from low screening adherence. It is imperative to synthesize the literature evaluating the effectiveness of interventions on CRC screening uptake in this population.

MATERIALS AND METHODS

In this systematic review and meta-analysis, Medline, CINAHL, Embase, and Cochrane CENTRAL were searched for U.S.-based interventions that: were published after 1998-January 2020; included African-American men; and evaluated CRC screening uptake explicitly. Checklist by Cochrane Collaboration and Joanna Brigg were utilized to assess risk of bias, and meta-regression and sensitivity analyses were employed to identify the most effective interventions.

RESULTS

Our final sample comprised 41 studies with 2 focused exclusively on African-American men. The most frequently adopted interventions were educational materials (39%), stool-based screening kits (14%), and patient navigation (11%). Most randomized controlled trials failed to provide details about the blinding of the participant recruitment method, allocation concealment method, and/or the outcome assessment. Due to high heterogeneity, meta-analysis was conducted among 17 eligible studies. Interventions utilizing stool-based kits or patient navigation were most effective at increasing CRC screening completion, with odds ratios of 9.60 (95% CI 2.89-31.82, p = 0.0002) and 2.84 (95% CI 1.23-6.49, p = 0.01). No evidence of publication bias was present for this study registered with the International Prospective Registry of Systematic Reviews (PROSPERO 2019 CRD42019119510).

CONCLUSIONS

Additional research is warranted to uncover effective, affordable interventions focused on increasing CRC screening completion among African-American men. When designing and implementing future multicomponent interventions, employing 4 or fewer interventions types may reduce bias risk. Since only 5% of the interventions solely focused on African-American men, future theory-driven interventions should consider recruiting samples comprised solely of this population.

Peer Support as an Ideal Solution for Racial/Ethnic Disparities in Colorectal Cancer Screening: Evidence from a Systematic Review and Meta-analysis

BACKGROUND

Low implementation of colorectal cancer screening in ethnic minorities is the main reason for racial and ethnic disparities in colorectal cancer morbidity and mortality. Peer support is widely used for promoting health care in ethnic minorities. However, whether it improves their acceptance to undergo the screening remains controversial.

OBJECTIVE

We performed a meta-analysis of the currently available studies to further explore its effectiveness.

DATA SOURCES

This meta-analysis was undertaken using PubMed, Embase, Scopus, the Cochrane Central Register of Controlled Trials, Cumulative Index to Nursing and Allied Health Literature, and PsycINFO for randomized controlled trials.

STUDY SELECTION

We included studies that compared peer support interventions among ethnic minorities versus other interventions to promote uptake of colorectal cancer screening.

RESULTS

Thirteen studies comprising 8090 participants met the eligibility criteria. Peer support intervention can increase colorectal cancer screening implementation and raise awareness and intention to undergo the screening in ethnic minorities more significantly than fecal occult blood test outreach, print, and usual care. Subgroup analysis showed that peer support intervention achieved great results in Asian Americans and intervention of peer counseling.

LIMITATIONS

The results of subgroup analysis had substantial heterogeneity, which may decrease the precision of our estimates.

CONCLUSIONS

Peer support can significantly improve the awareness about and the intention for receiving colorectal cancer screening in ethnic minorities and is an ideal choice for promoting the screening among ethnic minorities, particularly in a diverse community. Peer support intervention is recommended to promote the implementation of screening in Asian Americans. Peer counseling is worth promoting; however, church-based peer counseling programs require enhanced management to maintain their fidelity.

Demographic and psychosocial factors associated with limited health literacy in a community-based sample of older Black Americans

OBJECTIVES

Individuals with limited health literacy often experience suboptimal health outcomes. This study examined the frequency of limited health literacy and demographic and psychosocial factors associated with limited health literacy in a sample of older Black Americans.

METHODS

Participants (n = 330) enrolled in a community-based intervention to promote colorectal cancer (CRC) screening completed baseline surveys assessing health literacy with the Rapid Estimate of Adult Literacy in Medicine, Revised (REALM-R) test, CRC awareness, cancer fatalism, Preventive Health Model (PHM) constructs, and demographics.

RESULTS

Approximately 52% of participants had limited health literacy, the REALM-R score was 5.4 (SD = 2.7). Univariable correlates of limited health literacy were gender, employment, income, prior screening, cancer fatalism, CRC awareness, and PHM constructs (religious beliefs, salience/coherence, perceived susceptibility). Multivariable correlates of limited health literacy were male gender (OR = 2.3, CI = 1.4-3.8), unable to work (OR = 2.8, CI = 1.3-6.1), lower household income (OR = 3.0, CI = 1.6, 5.5), and higher PHM religious beliefs (OR = 1.1, CI = 1.0-1.2).

CONCLUSION

Limited health literacy was associated with multiple complex factors. Interventions should incorporate patient health literacy and low-literacy materials that can be delivered through multiple channels.

PRACTICE IMPLICATIONS

Future studies are needed to understand the role of health literacy in an individual's health behavior and the provision of effective healthcare.

Individual and Geospatial Characteristics Associated With Use and Nonuse of the Fecal Immunochemical Test (FIT) for Colorectal Cancer Screening in an Urban Minority Population

PURPOSE

Initiatives by the Centers for Disease Control and Prevention as well as the National Colorectal Cancer Roundtable aim to increase the rate of colorectal cancer (CRC) screening. We assess individual and geographic characteristics associated fecal immunochemical test (FIT) CRC screening over 3 years.

METHODS

This is a retrospective study of 1500 FIT kits which were mailed or opportunistically handed to eligible participants in Brooklyn, New York from January 2014 to December 2016. Eligibility criteria included increased risk for colon cancer, uninsured or underinsured, and a minimum age of 50 years to warrant CRC screening. We looked at the association of individual demographic characteristics and FIT screening by logistic regression using SPPS version 23 software. In addition, using ArcGIS, we coded patients address and layered census tract population information to find associations.

RESULTS

In total, 1367 Cancer Services Participants met our study criteria. The study sample was predominantly female (95.2%) and minority (46% African American, 24.7% Hispanic, 17.3% Caucasian, 11.4% Asian) and on average 59 years old (SD, 5.7). A large majority (73%) had household incomes below $20,000/year. Approximately half (49.9%) of all Cancer Services Participants returned their FIT kit. In participants who did not return their FIT kit, the majority were African American (41%), followed by Hispanics (26.5%), Caucasians (20.6%), and Asians (11.8%). Multivariable logistic regression showed that a screening history of prior colonoscopy or FIT, gender, ethnicity, and educational attainment were significantly associated with FIT CRC screening uptake (P<0.05). Geospatial mapping showed clusters of low screening uptake in areas of high poverty. Hot-spot analysis identified areas of significant vulnerability.

CONCLUSIONS

FIT uptake remains suboptimal. Individual predictors as well as area poverty is associated with low screening uptake. Geospatial mapping is an effective tool for evaluating CRC screening uptake.

A culturally and linguistically salient pilot intervention to promote colorectal cancer screening among Latinos receiving care in a Federally Qualified Health Center

Despite established benefits, colorectal cancer (CRC) screening is underutilized among Latinos/Hispanics. We conducted a pilot 2-arm randomized controlled trial evaluating efficacy of two intervention conditions on CRC screening uptake among Latinos receiving care in community clinics. Participants (N = 76) were aged 50-75, most were foreign-born, preferred to receive their health information in Spanish, and not up-to-date with CRC screening. Participants were randomized to either a culturally linguistically targeted Spanish-language fotonovela booklet and DVD intervention plus fecal immunochemical test [FIT] (the LCARES, Latinos Colorectal Cancer Awareness, Research, Education and Screening intervention group); or a non-targeted intervention that included a standard Spanish-language booklet plus FIT (comparison group). Measures assessed socio-demographic variables, health literacy, CRC screening behavior, awareness and beliefs. Overall, FIT uptake was 87%, exceeding the National Colorectal Cancer Roundtable's goal of 80% by 2018. The LCARES intervention group had higher FIT uptake than did the comparison group (90% versus 83%), albeit not statistically significant (P = 0.379). The LCARES intervention group was associated with greater increases in CRC awareness (P = 0.046) and susceptibility (P = 0.013). In contrast, cancer worry increased more in the comparison group (P = 0.045). Providing educational materials and a FIT kit to Spanish-language preferring Latinos receiving care in community clinics is a promising strategy to bolster CRC screening uptake to meet national targets.

Examining the Durability of Colorectal Cancer Screening Awareness and Health Beliefs Among Medically Underserved Patients: Baseline to 12 months Post-Intervention

The current study examines changes in awareness and health beliefs from baseline to 12 months post-intervention following receipt of one of two colorectal cancer (CRC) educational interventions that aimed to promote CRC screening among a racially and ethnically diverse and medically underserved population. Participants (N = 270) were enrolled in a randomized controlled trial to increase CRC screening and completed both baseline and 12-month follow-up assessments. Participants were aged 50-75, at average CRC risk, not up-to-date with CRC screening guidelines, and receiving care at one of three community-based clinics. Participants were randomized to receive either a targeted, low-literacy intervention informed by the Preventive Health Model [PHM] (photonovella and DVD plus fecal immunochemical test [FIT]) or a non-targeted intervention (standard educational brochure plus FIT). Changes in CRC awareness and health beliefs from baseline to 12 months were examined both within and between intervention groups using Student's t tests. Participants in both intervention conditions demonstrated an increase in CRC awareness, PHM social influence, and trust in the healthcare system (all p's < .0001), with no significant between-group differences. Among those receiving the targeted intervention, there also was an increase in PHM salience (p < .05). Among individuals receiving the non-targeted intervention, there was an increase in PHM response efficacy (p < .01) and PHM self-efficacy (p < .0001). Both CRC screening interventions promoted positive changes in awareness and several health beliefs from baseline to 12 months, suggesting important benefits of CRC education. Regardless of whether education was targeted or non-targeted, providing CRC screening education successfully promoted durable changes in awareness and health beliefs.

Recruitment Techniques and Strategies in a Community-Based Colorectal Cancer Screening Study of Men and Women of African Ancestry

BACKGROUND

Recruiting ethnically diverse Black participants to an innovative, community-based research study to reduce colorectal cancer screening disparities requires multipronged recruitment techniques.

OBJECTIVES

This article describes active, passive, and snowball recruitment techniques, and challenges and lessons learned in recruiting a diverse sample of Black participants.

METHODS

For each of the three recruitment techniques, data were collected on strategies, enrollment efficiency (participants enrolled/participants evaluated), and reasons for ineligibility.

RESULTS

Five hundred sixty individuals were evaluated, and 330 individuals were enrolled. Active recruitment yielded the highest number of enrolled participants, followed by passive and snowball. Snowball recruitment was the most efficient technique, with enrollment efficiency of 72.4%, followed by passive (58.1%) and active (55.7%) techniques. There were significant differences in gender, education, country of origin, health insurance, and having a regular physician by recruitment technique (p < .05).

DISCUSSION

Multipronged recruitment techniques should be employed to increase reach, diversity, and study participation rates among Blacks. Although each recruitment technique had a variable enrollment efficiency, the use of multipronged recruitment techniques can lead to successful enrollment of diverse Blacks into cancer prevention and control interventions.

Colorectal Cancer Screening in Black Men: Recommendations for Best Practices

Screening for colorectal cancer has been demonstrated to reduce colorectal cancer mortality. Blacks have a higher mortality from this malignancy, particularly men, yet screening rates in this population are often found to be lower than in whites. A modest literature demonstrates effective interventions that can increase screening rates in blacks; however, results are not consistent and ongoing work is required. Most work has not addressed specific barriers to screening in black men. Given the lack of studies on black men only, this study evaluated the state of research in the black population using a PubMed search. The authors provide commentary that proposes increased (1) state and local government support for collaborative programs with healthcare organizations, including patient navigation; (2) augmented community-organizing efforts to generate more attention to the need for colorectal cancer screening in the black community, with a focus on black men; and (3) federal research funding to promote investigation into new interventions and evaluation of existing ones. Specific recommendations for black men include lowering the screening age to 45years, increasing access to health care, the use of patient navigators, and improved reporting and monitoring of colorectal cancer screening rates.

Faecal immunochemical testing implementation to increase colorectal cancer screening in primary care

Colorectal cancer (CRC) is the second leading cause of cancer death in USA, and CRC screening remains suboptimal. The aim of this quality improvement was to increase CRC screening in the internal medicine clinic (IMC) patients, between the ages of 50–75 years, from a baseline rate of 50%–70% over 12 months with the introduction of faecal immunochemical test (FIT) testing. We used the Plan–Do–Study–Act (PDSA) method and performed a root cause analysis to identify barriers to acceptance of CRC screening. The quality improvement team created a driver diagram to identify and prioritise change ideas. We developed a process flow map to optimise opportunities to improve CRC screening. We performed eight PDSA cycles. The major components of interventions included: (1) leveraging health information technology; (2) optimising team work, (3) education to patient, physicians and IMC staff, (4) use of patient navigator for tracking FIT completion and (5) interactive workshops for the staff and physicians to learn motivational interview techniques. The outcome measure included CRC screening rates with either FIT or colonoscopy. The process measures included FIT order and completion rates. Data were analysed using a statistical process control and run charts. Four hundred and seven patients visiting the IMC were offered FIT, and 252 (62%) completed the test. Twenty-two (8.7%) of patients were FIT positive, 14 of those (63.6%) underwent a subsequent diagnostic colonoscopy. We achieved 75% CRC screening with FIT or colonoscopy within 12 months and exceeded our goal. Successful strategies included engaging the leadership, the front-line staff and a highly effective multidisciplinary team. For average-risk patients, FIT was the preferred method of screening. We were able to sustain a CRC screening rate of 75% during the 6-month postproject period. Sustainable annual FIT is required for successful CRC screening.

Understanding Cancer Worry Among Patients in a Community Clinic-Based Colorectal Cancer Screening Intervention Study

BACKGROUND

To reduce colorectal cancer (CRC) screening disparities, it is important to understand correlates of different types of cancer worry among ethnically diverse individuals.

OBJECTIVES

The current study examined the prevalence of three types of cancer worry (i.e., general cancer worry, CRC-specific worry, and worry about CRC test results) as well as sociodemographic and health-related predictors for each type of cancer worry.

METHODS

Participants were aged 50-75, at average CRC risk, nonadherent to CRC screening guidelines, and enrolled in a randomized controlled trial to increase CRC screening. Participants completed a baseline questionnaire assessing sociodemographics, health beliefs, healthcare experiences, and three cancer worry measures. Associations between study variables were examined with separate univariate and multivariable logistic regression models.

RESULTS

Responses from a total of 416 participants were used. Of these, 47% reported experiencing moderate-to-high levels of general cancer worry. Predictors of general cancer worry were salience and coherence (aOR = 1.1, 95% CI [1.0, 1.3]), perceived susceptibility (aOR = 1.2, 95% CI [1.1, 1.3), and social influence (aOR = 1.1, 95% CI [1.0, 0.1]). Fewer (23%) reported moderate-to-high levels of CRC-specific worry or CRC test worry (35%). Predictors of CRC worry were perceived susceptibility (aOR = 1.4, 95% CI [1.3, 1.6]) and social influence (aOR = 1.1, 95% CI [1.0, 1.2]); predictors of CRC test result worry were perceived susceptibility (aOR = 1.2, 95% CI [1.1, 1.3) and marital status (aOR = 2.0, 95% CI [1.1, 3.7] for married/partnered vs. single and aOR = 2.3, 95% CI [1.3, 4.1] for divorced/widowed vs. single).

DISCUSSION

Perceived susceptibility consistently predicted the three types of cancer worry, whereas other predictors varied between cancer worry types and in magnitude of association. The three types of cancer worry were generally predicted by health beliefs, suggesting potential malleability. Future research should include multiple measures of cancer worry and clear definitions of how cancer worry is measured.

Socioeconomic and ethnic inequities within organised colorectal cancer screening programmes worldwide

OBJECTIVE

Colorectal cancer (CRC) screening programmes can reduce CRC mortality. However, the implementation of a screening programme may create or exacerbate socioeconomic and ethnic health inequities if participation varies by subgroup. We determined which organised programmes characterise participation inequities by socioeconomic and ethnic subgroups, and assessed the variation in subgroup participation among programmes collecting group-specific data.

DESIGN

Employing a literature review and survey among leaders of national or regional screening programmes, this study identified published and unpublished data on participation by socioeconomic status and ethnicity. We assessed programmes offering faecal occult blood tests (FOBT) for screening. Primary outcome was screening participation rate.

RESULTS

Across 24 organised FOBT-screening programmes meeting the inclusion criteria, participation rates ranged from 21% to 73%. Most programmes (13/24, 54%) did not collect data on participation by socioeconomic status and ethnicity. Among the 11 programmes with data on participation by socioeconomic status, 90% (28/31 publications) reported lower participation among lower socioeconomic groups. Differences across socioeconomic gradients were moderate (66% vs 71%) to severe (35% vs 61%). Only six programmes reported participation results by ethnicity. Ethnic differences were moderate, though only limited data were available for evaluation.

CONCLUSIONS

Across organised CRC screening programmes worldwide, variation in participation by socioeconomic status and ethnicity is often not assessed. However, when measured, marked disparities in participation by socioeconomic status have been observed. Limited data were available to assess inequities by ethnicity. To avoid exacerbating health inequities, screening programmes should systematically monitor participation by socioeconomic status and ethnicity, and investigate and address determinants of low participation.

Health Literacy among Medically Underserved: The Role of Demographic Factors, Social Influence, and Religious Beliefs

The current study examined the sociodemographic and psychosocial variables that predicted being at risk for low health literacy among a population of racially and ethnically diverse patients accessing primary care services at community-based clinics. Participants (N = 416) were aged 50-75 years, currently not up-to-date with colorectal cancer (CRC) screening, at average CRC risk, and enrolled in a randomized controlled trial (RCT) aimed at promoting CRC screening. Participants completed a baseline interview that assessed health literacy as measured by Rapid Estimate of Adult Literacy in Medicine-Revised, sociodemographic factors, and psychosocial variables (e.g., health beliefs) prior to randomization and receipt of an intervention. Thirty-six percent of the participants were found to be at risk for low health literacy. Sociodemographic and psychosocial variables were assessed as predictors of being at risk for low health literacy using logistic regression. In the final model, predictors were male gender, being from a racial/ethnic minority group, being unable to work, having higher social influence scores, and having higher religious belief scores. These findings suggest several patient characteristics that may be associated with low health literacy, and highlight the importance of supporting all patients through simplified and clear communications and information to improve understanding of CRC screening information.

A randomized controlled trial of a multicomponent, targeted, low-literacy educational intervention compared with a nontargeted intervention to boost colorectal cancer screening with fecal immunochemical testing in community clinics

BACKGROUND

The objective of the current study was to improve colorectal cancer (CRC) screening uptake with the fecal immunochemical test (FIT). The current study investigated the differential impact of a multicomponent, targeted, low-literacy educational intervention compared with a standard, nontargeted educational intervention.

METHODS

Patients aged 50 to 75 years who were of average CRC risk and not up-to-date with CRC screening were recruited from either a federally qualified health center or a primary care community health clinic. Patients were randomized to the intervention condition (targeted photonovella booklet/DVD plus FIT kit) or comparison condition (standard Centers for Disease Control and Prevention brochure plus FIT kit). The main outcome was screening with FIT within 180 days of delivery of the intervention.

RESULTS

Of the 416 participants, 54% were female; the participants were racially and ethnically diverse (66% white, 10% Hispanic, and 28% African American), predominantly of low income, and insured (the majority had county health insurance). Overall, the FIT completion rate was 81%, with 78.1% of participants in the intervention versus 83.5% of those in the comparison condition completing FIT (P =  .17). In multivariate analysis, having health insurance was found to be the primary factor predicting a lack of FIT screening (adjusted odds ratio, 2.10; 95% confidence interval, 1.04-4.26 [P =  .04]).

CONCLUSIONS

The multicomponent, targeted, low-literacy materials were not found to be significantly different or more effective in increasing FIT uptake compared with the nontargeted materials. Provision of a FIT test plus education may provide a key impetus to improve the completion of CRC screening. The type of educational material (targeted vs nontargeted) may matter less. The findings of the current study provide a unique opportunity for clinics to adopt FIT and to choose the type of patient education materials based on clinic, provider, and patient preferences.
