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

Protocol paper for an implementation science approach to promoting colorectal cancer screening in Federally Qualified Health Center clinics: A stepped-wedge, multilevel intervention trial

Background

Colorectal cancer is the third leading cause of cancer-related deaths in the United States. Despite the Healthy People 2030 goal of 70.5%, colorectal cancer (CRC) screening rates in Federally Qualified Health Centers (FQHCs) are suboptimal at about 40%. The Colorectal Cancer Awareness, Research, Education and Screening-Rural Expansion, Access, and Capacity for Health (CARES-REACH) study seeks to address this disparity and accelerate the adoption and utilization of effective, evidence-based CRC screening practices. This paper describes the CARES-REACH study design and implementation methods.

Methods

Informed by a community-based participatory research (CBPR) framework and enriched by implementation science approaches, CARES-REACH features a stepped wedge design with extension for maintenance to support an implementation strategy focused on multiple levels: organizational, provider, and patient levels that entail processes to boost initial and repeat screening among average risk and age-eligible adults. This multilevel study entails the implementation of a core set of evidence-based interventions (EBIs) that include low literacy patient education (English, Spanish, and Haitian Creole language); provider education, system-wide electronic medical record (EMR) tools including provider prompts and patient reminders, FIT (fecal immunochemical test) kit distribution, plus an organization-wide cancer control champion who motivates providers, coaches and navigates patients, and monitors system-wide CRC screening activities.

Strategic use of resources to enhance colorectal cancer screening for patients with diabetes (SURE: CRC4D) in federally qualified health centers: a protocol for hybrid type ii effectiveness-implementation trial

BACKGROUND

Persons with diabetes have 27% elevated risk of developing colorectal cancer (CRC) and are disproportionately from priority health disparities populations. Federally qualified health centers (FQHCs) struggle to implement CRC screening programs for average risk patients. Strategies to effectively prioritize and optimize CRC screening for patients with diabetes in the primary care safety-net are needed.

METHODS

Guided by the Exploration, Preparation, Implementation and Sustainment Framework, we conducted a stakeholder-engaged process to identify multi-level change objectives for implementing optimized CRC screening for patients with diabetes in FQHCs. To identify change objectives, an implementation planning group of stakeholders from FQHCs, safety-net screening programs, and policy implementers were assembled and met over a 7-month period. Depth interviews (n = 18-20) with key implementation actors were conducted to identify and refine the materials, methods and strategies needed to support an implementation plan across different FQHC contexts. The planning group endorsed the following multi-component implementation strategies: identifying clinic champions, development/distribution of patient educational materials, developing and implementing quality monitoring systems, and convening clinical meetings. To support clinic champions during the initial implementation phase, two learning collaboratives and bi-weekly virtual facilitation will be provided. In single group, hybrid type 2 effectiveness-implementation trial, we will implement and evaluate these strategies in a in six safety net clinics (n = 30 patients with diabetes per site). The primary clinical outcomes are: (1) clinic-level colonoscopy uptake and (2) overall CRC screening rates for patients with diabetes assessed at baseline and 12-months post-implementation. Implementation outcomes include provider and staff fidelity to the implementation plan, patient acceptability, and feasibility will be assessed at baseline and 12-months post-implementation.

DISCUSSION

Study findings are poised to inform development of evidence-based implementation strategies to be tested for scalability and sustainability in a future hybrid 2 effectiveness-implementation clinical trial. The research protocol can be adapted as a model to investigate the development of targeted cancer prevention strategies in additional chronically ill priority populations.

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.

Patient Navigation Plus Tailored Digital Video Disc Increases Colorectal Cancer Screening Among Low-Income and Minority Patients Who Did Not Attend a Scheduled Screening Colonoscopy: A Randomized Trial

BACKGROUND

Up to 50% of people scheduled for screening colonoscopy do not complete this test and no studies have focused on minority and low-income populations. Interventions are needed to improve colorectal cancer (CRC) screening knowledge, reduce barriers, and provide alternative screening options. Patient navigation (PN) and tailored interventions increase CRC screening uptake, however there is limited information comparing their effectiveness or the effect of combining them.

PURPOSE

Compare the effectiveness of two interventions to increase CRC screening among minority and low-income individuals who did not attend their screening colonoscopy appointment-a mailed tailored digital video disc (DVD) alone versus the mailed DVD plus telephone-based PN compared to usual care.

METHODS

Patients (n = 371) aged 45-75 years at average risk for CRC who did not attend a screening colonoscopy appointment were enrolled and were randomized to: (i) a mailed tailored DVD; (ii) the mailed DVD plus phone-based PN; or (iii) usual care. CRC screening outcomes were from electronic medical records at 12 months. Multivariable logistic regression analyses were used to study intervention effects.

RESULTS

Participants randomized to tailored DVD plus PN were four times more likely to complete CRC screening compared to usual care and almost two and a half times more likely than those who were sent the DVD alone.

CONCLUSIONS

Combining telephone-based PN with a mailed, tailored DVD increased CRC screening among low-income and minority patients who did not attend their screening colonoscopy appointments and has potential for wide dissemination.

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.

Anticipatory anxiety and participation in cancer screening. A systematic review

OBJECTIVES

To synthesize current evidence on the association between anticipatory anxiety, defined as apprehension-specific negative affect that may be experienced when exposed to potential threat or uncertainty, and cancer screening to better inform strategies to maximize participation rates.

METHODS

Searches related to cancer screening and anxiety were conducted in seven electronic databases (APA PsycINFO, Scopus, Web of Science, Embase, Cochrane Library, PubMed, CINAHL), with potentially eligible papers screened in Covidence. Data extraction was conducted independently by multiple authors. Barriers to cancer screening for any type of cancer and relationships tested between anticipatory anxiety and cancer screening and intention were categorized and compared according to the form and target of anxiety and cancer types.

RESULTS

A total of 74 articles (nparticipants  = 119,990) were included, reporting 103 relationships tested between anticipatory anxiety and cancer screening and 13 instances where anticipatory anxiety was reported as a barrier to screening. Anticipatory anxiety related to a possible cancer diagnosis was often associated with increased screening, while general anxiety showed no consistent relationship. Negative relationships were often found between anxiety about the screening procedure and cancer screening.

CONCLUSION

Anticipatory anxiety about a cancer diagnosis may promote screening participation, whereas a fear of the screening procedure could be a barrier. Public health messaging and primary prevention practitioners should acknowledge the appropriate risk of cancer, while engendering screening confidence and highlighting the safety and comfort of screening tests.

Interventions for improving health literacy in migrants

BACKGROUND

Health literacy (HL) is a determinant of health and important for autonomous decision-making. Migrants are at high risk for limited HL. Improving HL is important for equitable promotion of migrants' health.

OBJECTIVES

To assess the effectiveness of interventions for improving HL in migrants. To assess whether female or male migrants respond differently to the identified interventions.

SEARCH METHODS

We ran electronic searches to 2 February 2022 in CENTRAL, MEDLINE, Embase, PsycInfo and CINAHL. We also searched trial registries. We used a study filter for randomised controlled trials (RCTs) (RCT classifier).

SELECTION CRITERIA

We included RCTs and cluster-RCTs addressing HL either as a concept or its components (access, understand, appraise, apply health information).

DATA COLLECTION AND ANALYSIS

We used the methodological procedures recommended by Cochrane and followed the PRISMA-E guidelines. Outcome categories were: a) HL, b) quality of life (QoL), c) knowledge, d) health outcomes, e) health behaviour, f) self-efficacy, g) health service use and h) adverse events. We conducted meta-analysis where possible, and reported the remaining results as a narrative synthesis.

MAIN RESULTS

We included 28 RCTs and six cluster-RCTs (8249 participants), all conducted in high-income countries. Participants were migrants with a wide range of conditions. All interventions were adapted to culture, language and literacy. We did not find evidence that HL interventions cause harm, but only two studies assessed adverse events (e.g. anxiety). Many studies reported results for short-term assessments (less than six weeks after total programme completion), reported here. For several comparisons, there were also findings at later time points, which are presented in the review text. Compared with no HL intervention (standard care/no intervention) or an unrelated HL intervention (similar intervention but different information topic) Self-management programmes (SMP) probably improve self-efficacy slightly (standardised mean difference (SMD) 0.28, 95% confidence interval (CI) 0.06 to 0.50; 2 studies, 333 participants; moderate certainty). SMP may improve HIV-related HL (understanding (mean difference (MD) 4.25, 95% CI 1.32 to 7.18); recognition of HIV terms (MD 3.32, 95% CI 1.28 to 5.36)) (1 study, 69 participants). SMP may slightly improve health behaviours (3 studies, 514 participants), but may have little or no effect on knowledge (2 studies, 321 participants) or subjective health status (MD 0.38, 95% CI -0.13 to 0.89; 1 study, 69 participants) (low certainty). We are uncertain of the effects of SMP on QoL, health service use or adverse events due to a lack of evidence. HL skills building courses (HLSBC) may improve knowledge (MD 10.87, 95% CI 5.69 to 16.06; 2 studies, 111 participants) and any generic HL (SMD 0.48, 95% CI 0.20 to 0.75; 2 studies, 229 participants), but may have little or no effect on depression literacy (MD 0.17, 95% CI -1.28 to 1.62) or any health behaviour (2 studies, 229 participants) (low certainty). We are uncertain if HLSBC improve QoL, health outcomes, health service use, self-efficacy or adverse events, due to very low-certainty or a lack of evidence. Audio-/visual education without personal feedback (AVE) probably improves depression literacy (MD 8.62, 95% CI 7.51 to 9.73; 1 study, 202 participants) and health service use (MD -0.59, 95% CI -1.11 to -0.07; 1 study, 157 participants), but probably has little or no effect on health behaviour (risk ratio (RR) 1.07, 95% CI 0.91 to 1.25; 1 study, 135 participants) (moderate certainty). AVE may improve self-efficacy (MD 3.51, 95% CI 2.53 to 4.49; 1 study, 133 participants) and may slightly improve knowledge (MD 8.44, 95% CI -2.56 to 19.44; 2 studies, 293 participants) and intention to seek depression treatment (MD 1.8, 95% CI 0.43 to 3.17), with little or no effect on depression (SMD -0.15, 95% CI -0.40 to 0.10) (low certainty). No evidence was found for QoL and adverse events. Adapted medical instruction may improve understanding of health information (3 studies, 478 participants), with little or no effect on medication adherence (MD 0.5, 95% CI -0.1 to 1.1; 1 study, 200 participants) (low certainty). No evidence was found for QoL, health outcomes, knowledge, health service use, self-efficacy or adverse events. Compared with written information on the same topic SMP probably improves health numeracy slightly (MD 0.7, 95% CI 0.15 to 1.25) and probably improves print literacy (MD 9, 95% CI 2.9 to 15.1; 1 study, 209 participants) and self-efficacy (SMD 0.47, 95% CI 0.3 to 0.64; 4 studies, 552 participants) (moderate certainty). SMP may improve any disease-specific HL (SMD 0.67, 95% CI 0.27 to 1.07; 4 studies, 955 participants), knowledge (MD 11.45, 95% CI 4.75 to 18.15; 6 studies, 1101 participants) and some health behaviours (4 studies, 797 participants), with little or no effect on health information appraisal (MD 1.15, 95% CI -0.23 to 2.53; 1 study, 329 participants) (low certainty). We are uncertain whether SMP improves QoL, health outcomes, health service use or adverse events, due to a lack of evidence or low/very low-certainty evidence. AVE probably has little or no effect on diabetes HL (MD 2, 95% CI -0.15 to 4.15; 1 study, 240 participants), but probably improves information appraisal (MD -9.88, 95% CI -12.87 to -6.89) and application (RR 1.51, 95% CI 1.29 to 1.77) (1 study, 608 participants; moderate certainty). AVE may slightly improve knowledge (MD 8.35, 95% CI -0.32 to 17.02; low certainty). No short-term evidence was found for QoL, depression, health behaviour, self-efficacy, health service use or adverse events. AVE compared with another AVE We are uncertain whether narrative videos are superior to factual knowledge videos as the evidence is of very low certainty. Gender differences Female migrants' diabetes HL may improve slightly more than that of males, when receiving AVE (MD 5.00, 95% CI 0.62 to 9.38; 1 study, 118 participants), but we do not know whether female or male migrants benefit differently from other interventions due to very low-certainty or a lack of evidence.

AUTHORS' CONCLUSIONS

Adequately powered studies measuring long-term effects (more than six months) of HL interventions in female and male migrants are needed, using well-validated tools and representing various healthcare systems.

Transcreation matters: A learner centric participatory approach for adapting cancer prevention messages for Latinos

BACKGROUND

Advancing health equity requires innovative patient education approaches for adapting English-language evidence-based interventions (EBIs) to resonate with multicultural, multilingual audiences.

OBJECTIVE

Examine the benefit, functionality, and practical considerations of transcreation (translation + cultural adaptation) as a critical and salient learner-centric process for developing a Spanish-language intervention (photonovella + video): Un examen sencillo para un colon saludable (A simple test for a healthy colon).

PATIENT/COMMUNITY INVOLVEMENT

We involved patients/community members in a participatory reflective process, from problem identification to intervention design, development, delivery, and impact measurement.

METHODS

A community-based participatory research (CBPR) approach involving formative research plus systematic iterative pretesting and learner verification checks augmented by a community advisory board guided the transcreation processes.

RESULTS

Data collected using a learner-centric approach effectively produced a new Spanish-language EBI and substantiated the value of co-learner/co-design methods. Learner-centric methods identified cultural nuances that were treated as knowledge and integrated into the intervention materials and study design. Pilot testing of the intervention among Latinos receiving care at community clinics demonstrated improved initial colorectal cancer screening uptake, awareness, and perceived susceptibility.

DISCUSSION

Inherent in the transcreation process was learner involvement that informed essential modification and adaptation of the materials. The transcreation methods led to the development of a culturally salient intervention that maintained theoretical integrity and message intent as well as behavioral activation. Findings have broad implications for the creation and transfer of EBIs to new audiences for greater adoption, engagement, and 'reach' of interventions.

PRACTICAL VALUE

Transcreation aligns with a growing paradigm shift in health communication science that brings to light the beneficial effect that construction and application of cultural knowledge has on patient education toward health equity.

Social determinants of health and US cancer screening interventions: A systematic review

There remains a need to synthesize linkages between social determinants of health (SDOH) and cancer screening to reduce persistent inequities contributing to the US cancer burden. The authors conducted a systematic review of US-based breast, cervical, colorectal, and lung cancer screening intervention studies to summarize how SDOH have been considered in interventions and relationships between SDOH and screening. Five databases were searched for peer-reviewed research articles published in English between 2010 and 2021. The Covidence software platform was used to screen articles and extract data using a standardized template. Data items included study and intervention characteristics, SDOH intervention components and measures, and screening outcomes. The findings were summarized using descriptive statistics and narratives. The review included 144 studies among diverse population groups. SDOH interventions increased screening rates overall by a median of 8.4 percentage points (interquartile interval, 1.8-18.8 percentage points). The objective of most interventions was to increase community demand (90.3%) and access (84.0%) to screening. SDOH interventions related to health care access and quality were most prevalent (227 unique intervention components). Other SDOH, including educational, social/community, environmental, and economic factors, were less common (90, 52, 21, and zero intervention components, respectively). Studies that included analyses of health policy, access to care, and lower costs yielded the largest proportions of favorable associations with screening outcomes. SDOH were predominantly measured at the individual level. This review describes how SDOH have been considered in the design and evaluation of cancer screening interventions and effect sizes for SDOH interventions. Findings may guide future intervention and implementation research aiming to reduce US screening inequities.

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.

Mediators of screening uptake in a colorectal cancer screening intervention among Hispanics

Background

Colorectal cancer (CRC) is the second leading cause of cancer deaths in the USA. Although a number of CRC screening tests have been established as being effective for CRC prevention and early detection, rates of CRC screening test completion in the US population remain suboptimal, especially among the uninsured, recent immigrants and Hispanics. In this study, we used a structural equation modelling approach to identify factors influencing screening test completion in a successful CRC screening program that was implemented in an uninsured Hispanic population. This information will enhance our understanding of influences on CRC screening among historically underscreened populations.

Methods

We used generalized structural equation models (SEM) utilizing participant reported information collected through a series of surveys. We identified direct and indirect pathways through which cofactors, CRC knowledge and individual Health Belief Model constructs (perceived benefits, barriers, susceptibility, fatalism and self-efficacy) and a latent psychosocial health construct mediated screening in an effective prospective randomized CRC screening intervention that was tailored for uninsured Hispanic Americans.

Results

Seven hundred twenty-three participants were eligible for inclusion; mean age was 56 years, 79.7% were female, and 98.9% were Hispanic. The total intervention effect was comparable in both models, with both having a direct and indirect effect on screening completion (n = 715, Model 1: RC = 2.46 [95% CI: 2.20, 2.71, p < 0.001]; n = 699, Model 2 RC =2.45, [95% CI: 2.18, 2.72, p < 0.001]. In Model 1, 32% of the overall effect was mediated by the latent psychosocial health construct (RC = 0.79, p < 0.001) that was in turn mainly influenced by self-efficacy, perceived benefits and fatalism. In Model 2, the most important individual mediators were self-efficacy (RC = 0.24, p = 0.013), and fatalism (RC = 0.07, p = 0.033).

Conclusion

This study contributes to our understanding of mediators of CRC screening and suggests that targeting self-efficacy, perceived benefits and fatalism could maximize the effectiveness of CRC screening interventions particularly in Hispanic populations.

Persistent Barriers to Colorectal Cancer Screening Completion Amid Centralized Outreach: A Mixed Methods Study

PURPOSE

To understand patient experiences and persistent barriers to colorectal cancer (CRC) screening amid centralized outreach at urban family medicine practices.

APPROACH

Following a pragmatic trial assessing mailed fecal immunochemical test (FIT) outreach, we invited a subset of participants to complete a semi-structured qualitative interview and structured questionnaire.

SETTING

Single urban academic healthcare system.

PARTICIPANTS

Sixty patients who were eligible and overdue for CRC screening at the time of trial enrollment.

METHOD

Using Andersen's Behavioral Model, we developed an interview guide to systematically assess factors shaping screening decisions and FIT uptake. Close-ended responses were analyzed using descriptive statistics. Qualitative data were analyzed using the constant comparative method.

RESULTS

Most participants (82%) self-reported that they had ever completed any modality of CRC screening, and nearly half (43%) completed the mailed FIT during the trial. Most patients (60%) preferred FIT to colonoscopy due to its private, convenient, and non-invasive nature; however, persistent barriers related to screening beliefs including fear of test results and cancer treatment still prevented some patients from completing any form of CRC screening.

CONCLUSIONS

Mailed FIT can overcome many structural barriers to CRC screening, yet clear communication and follow-up amid centralized outreach are essential. For some patients, tailored outreach or navigation to address screening-related fears or other screening beliefs may be needed to ensure timely completion of CRC screening.

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.

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

BACKGROUND

Early detection through screening can reduce colorectal cancer (CRC) mortality, but approximately 33% of adults aged 50-75 are not getting screened as recommended. Many interventions to increase CRC screening have been tested, but clinical and community organizations may be challenged in identifying the optimum programs and program materials to increase screening and ultimately reduce CRC mortality.

METHODS

We conducted a scoping review to characterize existing, US-based interventions to improve CRC screening and to identify gaps in the literature. We used t-tests and correlations to analyze the relationship between project features and intervention effect sizes.

RESULTS

The overall effect sizes were + 16% for changes in screening by any modality. The average effect sizes were greater for projects with more components, used patient navigation, and provided free/low-cost testing.

CONCLUSION

Interventions varied greatly in terms of follow-up time, test modality, and data sources. Organizations seeking to implement a program aimed at increasing CRC screening should consider both intervention components and relevant program materials.

Health Literacy Interventions in Cancer: a Systematic Review

Approximately one-third of adults in the United States (U.S.) have limited health literacy. Those with limited health literacy often have difficultly navigating the health care environment, including navigating care across the cancer continuum (e.g., prevention, screening, diagnosis, treatment). Evidence-based interventions to assist adults with limited health literacy improve health outcomes; however, little is known about health literacy interventions in the context of cancer and their impact on cancer-specific health outcomes. The purpose of this review was to identify and characterize the literature on health literacy interventions across the cancer care continuum. Specifically, our aim was to review the strength of evidence, outcomes assessed, and intervention modalities within the existing literature reporting health literacy interventions in cancer. Our search yielded 1036 records (prevention/screening n = 174; diagnosis/treatment n = 862). Following deduplication and review for inclusion criteria, we analyzed 87 records of intervention studies reporting health literacy outcomes, including 45 pilot studies (prevention/screening n = 24; diagnosis/treatment n = 21) and 42 randomized controlled trials or quasi-experimental trials (prevention/screening n = 31; diagnosis/treatment n = 11). This literature included 36 unique interventions (prevention/screening n = 28; diagnosis/treatment n = 8), mostly in the formative stages of intervention development, with few assessments of evidence-based interventions. These gaps in the literature necessitate further research in the development and implementation of evidence-based health literacy interventions to improve cancer outcomes.

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.

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.

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.

'Simple and easy:' providers' and latinos' perceptions of the fecal immunochemical test (FIT) for colorectal cancer screening

Objective: Colorectal cancer (CRC) screening efforts have effectively reduced CRC morbidity and mortality, yet screening remains relatively low among Latinos. The study's purpose was to document the awareness/knowledge of Fecal Immunochemical Test (FIT) among Latinos, gain better understanding of patient and health care provider perceptions about FIT, and explore the feasibility of adoption/uptake.Design/Methods: The study was guided by qualitative, ethnography design and methods. Eight focus groups (FG) with patients who self-identified as Hispanic/Latino between 50-75 years of age and key informant interviews with providers (N = 10) were conducted followed by a brief demographic questionnaire.Results: Awareness levels varied based on prior screening experiences among patients and providers. Both patients and providers believed the FIT is simple and easy to use; although, a minority of patients expressed doubts about the efficacy of the FIT when compared to colonoscopy.Conclusions: Despite the increasing acceptance of the FIT among the health care community, a significant lag time still exists among our study's populations. Study findings speak to novelty of the FIT test among underserved populations and the health disparity gap between health innovations/discoveries. Increased awareness and education efforts about the efficacy coupled with information about its accessibility, ease, and user instructions may increase the adoption of FIT.

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.

Formative Research on Knowledge and Preferences for Stool-based Tests compared to Colonoscopy: What Patients and Providers Think

The rates of colorectal cancer (CRC) screening in the U.S. remain below national targets, so many people at risk are not being screened. The objective of this qualitative research project was to assess patient and provider knowledge and preferences about CRC screening modalities and specifically the use of the fecal immunochemical test (FIT) as a first line screening choice. Nine focus groups were conducted with a medically underserved patient population and qualitative interviews were administered to their medical providers. Thematic analysis was used to synthesize key findings. Both providers and patients thought that the FIT would be a good option for CRC screening both as an individual choice and for an overall program approach. The test is less expensive and therefore more readily available for patients compared to colonoscopy. Overall, there was consensus that the FIT offers a reasonably priced, simple approach to CRC screening which has broad appeal to both providers and patients. Concerns identified by patients and providers included the possibility of false positives with the FIT which could be caused by test contamination or failing to perform the test properly. Patients also described feelings of disgust toward performing the FIT and difficulties in following the instructions. Study findings indicate provider and patient support for using the FIT for CRC screening at both the individual and system-wide levels of implementation. While barriers to the use of the FIT were listed, benefits of using the FIT were perceived as positive motivators to engage previously unscreened and uninsured or under-insured individuals in CRC screening.

Factors Affecting Adherence in a Pragmatic Trial of Annual Fecal Immunochemical Testing for Colorectal Cancer

BACKGROUND

Colorectal cancer screening by fecal immunochemical test (FIT) reduces the burden of colorectal cancer. However, effectiveness relies on annual adherence, which presents challenges for clinic staff and patients.

OBJECTIVE

Describe FIT return rates and identify factors associated with FIT adherence over 2 years in a mailed FIT outreach program in federally qualified health centers.

DESIGN

Observational study nested in the Strategies and Opportunities to Stop Colon Cancer in Priority Populations (STOP CRC) trial. Five thousand one hundred ninety-five patients had an initial FIT order and were followed for ≥ 2 years (3574 also had a FIT order in the second year).

MAIN MEASURES

FIT return percent in each year and patient- and neighborhood-level characteristics associated with FIT adherence.

KEY RESULTS

Overall, the proportion of FIT orders that were completed was 46% in the patients' first year and 41% in the patients' second year. Of the 5195 patients with a FIT order in year 1, 3574 (69%) also had a FIT order in year 2 (71% of year 1 adherers and 67% of year 1 non-adherers, p = 0.009). Among those with a FIT order in the second year, the FIT return rate was about twice as high among those who were adherent in the first year (952/1674, or 57%) as among those who were not (531/1900, or 28%, p < 0.0001). Patient-level characteristics associated with higher odds of FIT return were a history of FIT screening at baseline, age over 65 (vs 50-65), no current tobacco use, recent receipt of a mammogram or flu vaccine, Asian ancestry (compared to non-Hispanic white), and non-English preference. The only neighborhood factor associated with lower FIT return rate was patient's larger residential city size.

CONCLUSION

Our findings can inform the customization of programs to promote FIT return among patients who receive care at federally qualified health centers.

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.

Population health interventions to improve colorectal cancer screening by fecal immunochemical tests: A systematic review

Despite clear evidence that colorectal cancer (CRC) screening reduces mortality, screening, including fecal immunochemical tests (FIT), is underutilized. We conducted a systematic review to determine the evidence of efficacy of interventions to improve FIT completion that could be scaled and utilized in population health management. We systematically searched publication databases for studies evaluating provider- or system-level interventions to improve CRC screening by FIT between 1 January 1996 and 13 December 2017 without language restrictions. Twenty articles describing 25 studies were included, 23 were randomized controlled trials with 1 quasi-experimental and 1 observational study. Ten studies discussed mailed FIT outreach, 4 pre-FIT patient reminders, 3 tailored patient messages, 2 post-FIT reminders, 2 paired FIT with influenza vaccinations, 2 provider alerts and 1 study each described the use of high-quality small media and patient financial incentives. Mailed FIT outreach was consistently effective with median improvement in CRC screening of 21.5% (interquartile range (IQR) 13.6%-29.0%). FIT paired with vaccinations led to a median 15.9% (IQR 15.6%-16.3%) improvement, while pre-FIT and post-FIT reminders demonstrated modest efficacy with median 4.1% (IQR 3.6%-6.7%) and 3.1% (IQR 2.9%-3.3%) improvement in CRC screening, respectively. More than half the studies were at high or unclear risk of bias; heterogeneous study designs and characteristics precluded meta-analysis. FIT-based CRC screening programs utilizing multilevel interventions (e.g. mailed FIT outreach, FIT paired with other preventative services, and provider alerts) have the potential to significantly increase screening participation. However, such programs must also follow-up patients with abnormal FIT results.

Evaluation of Interventions Intended to Increase Colorectal Cancer Screening Rates in the United States: A Systematic Review and Meta-analysis

IMPORTANCE

Colorectal cancer screening (CRC) is recommended by all major US medical organizations but remains underused.

OBJECTIVE

To identify interventions associated with increasing CRC screening rates and their effect sizes.

DATA SOURCES

PubMed, Cumulative Index to Nursing and Allied Health Literature, the Cochrane Library, and ClinicalTrials.gov were searched from January 1, 1996, to August 31, 2017. Key search terms included colorectal cancer and screening.

STUDY SELECTION

Randomized clinical trials of US-based interventions in clinical settings designed to improve CRC screening test completion in average-risk adults.

DATA EXTRACTION AND SYNTHESIS

At least 2 investigators independently extracted data and appraised each study's risk of bias. Where sufficient data were available, random-effects meta-analysis was used to obtain either a pooled risk ratio (RR) or risk difference (RD) for screening completion for each type of intervention.

MAIN OUTCOMES AND MEASURES

The main outcome was completion of CRC screening. Examination included interventions to increase completion of (1) initial CRC screening by any recommended modality, (2) colonoscopy after an abnormal initial screening test result, and (3) continued rounds of annual fecal blood tests (FBTs).

RESULTS

The main review included 73 randomized clinical trials comprising 366 766 patients at low or medium risk of bias. Interventions that were associated with increased CRC screening completion rates compared with usual care included FBT outreach (RR, 2.26; 95% CI, 1.81-2.81; RD, 22%; 95% CI, 17%-27%), patient navigation (RR, 2.01; 95% CI, 1.64-2.46; RD, 18%; 95% CI, 13%-23%), patient education (RR, 1.20; 95% CI, 1.06-1.36; RD, 4%; 95% CI, 1%-6%), patient reminders (RR, 1.20; 95% CI, 1.02-1.41; RD, 3%; 95% CI, 0%-5%), clinician interventions of academic detailing (RD, 10%; 95% CI, 3%-17%), and clinician reminders (RD, 13%; 95% CI, 8%-19%). Combinations of interventions (clinician interventions or navigation added to FBT outreach) were associated with greater increases than single components (RR, 1.18; 95% CI, 1.09-1.29; RD, 7%; 95% CI, 3%-11%). Repeated mailed FBTs with navigation were associated with increased annual FBT completion (RR, 2.09; 95% CI, 1.91-2.29; RD, 39%; 95% CI, 29%-49%). Patient navigation was not associated with colonoscopy completion after an initial abnormal screening test result (RR, 1.21; 95% CI, 0.92-1.60; RD, 14%; 95% CI, 0%-29%).

CONCLUSIONS AND RELEVANCE

Fecal blood test outreach and patient navigation, particularly in the context of multicomponent interventions, were associated with increased CRC screening rates in US trials. Fecal blood test outreach should be incorporated into population-based screening programs. More research is needed on interventions to increase adherence to continued FBTs, follow-up of abnormal initial screening test results, and cost-effectiveness and other implementation barriers for more intensive interventions, such as navigation.

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.

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.

An eHealth Intervention to Increase Physical Activity and Healthy Eating in Older Adult Cancer Survivors: Summative Evaluation Results

Background

A healthy lifestyle is associated with improved quality of life among cancer survivors, yet adherence to health behavior recommendations is low.

Objective

This pilot trial developed and tested the feasibility of a tailored eHealth program to increase fruit and vegetable consumption and physical activity among older, long-term cancer survivors.

Methods

American Cancer Society (ACS) guidelines for cancer survivors were translated into an interactive, tailored health behavior program on the basis of Social Cognitive Theory. Patients (N=86) with a history of breast (n=83) or prostate cancer (n=3) and less than 5 years from active treatment were randomized 1:1 to receive either provider advice, brief counseling, and the eHealth program (intervention) or advice and counseling alone (control). Primary outcomes were self-reported fruit and vegetable intake and physical activity.

Results

About half (52.7%, 86/163) of the eligible patients consented to participate. The most common refusal reasons were lack of perceived time for the study (32/163) and lack of interest in changing health behaviors (29/163). Furthermore, 72% (23/32) of the intervention group reported using the program and most would recommend it to others (56%, 14/25). Qualitative results indicated that the intervention was highly acceptable for survivors. For behavioral outcomes, the intervention group reported increased fruit and vegetable consumption. Self-reported physical activity declined in both groups.

Conclusions

The brief intervention showed promising results for increasing fruit and vegetable intake. Results and participant feedback suggest that providing the intervention in a mobile format with greater frequency of contact and more indepth information would strengthen treatment effects.
