A Multilevel Approach to Understand the Context and Potential Solutions for Low Colorectal Cancer (CRC) Screening Rates in Rural Appalachia Clinics

A socioecological taxonomy of determinants to colorectal cancer screening in black men: Insights from a mixed-methods systematic review

Background

In the United States, African/Black American (henceforth Black) men face significantly higher mortality rates from colorectal cancer (CRC) compared to other gender, racial, and ethnic groups. Although CRC is preventable and treatable with early detection, screening rates among Black men remain low. This study aimed to synthesize existing literature on the barriers and facilitators (determinants) of CRC screening to offer guidance to primary care teams in their efforts to improve screening uptake.

Methods

We performed a comprehensive systematic review of full-text, peer-reviewed studies published in English to explore the various determinants influencing CRC screening among Black men. Using key terms like "Black or African American," "male," and "colorectal cancer screening," we searched databases including PubMed, PsychInfo, CINAHL, and Embase, published between 2009 and 2022.

Findings

The search identified 1235 articles, with 54 meeting the inclusion criteria. Most studies were cross-sectional, examining determinants across the socioecological system. Key barriers included a lack of CRC screening knowledge, poor patient-provider communication, lack of access to screening, and medical mistrust stemming from systemic racism. Significant facilitators included aging, receiving a provider recommendation, having social support, and effective culturally appropriate outreach strategies.

Conclusions

Key themes and significant findings from the review provide actionable strategies for primary care teams. These include enhancing knowledge about CRC screening within the patient population, improving patient-provider interactions, and reducing barriers to accessing screening. Future research should aim to develop culturally appropriate and collaborative preventive care strategies to improve screening adherence and CRC-related outcomes.

Social determinants and participation in fecal occult blood test based colorectal cancer screening: A qualitative systematic review and meta-synthesis

ISSUE ADDRESSED

Colorectal cancer (CRC) screening through fecal occult blood testing (FOBT) has saved thousands of lives globally with multiple countries adopting comprehensive population wide screening programs. Participation rates in FOBT based CRC screening for the socially and economically disadvantaged remains low. The aim of this systematic review is to explore empirical evidence that will guide targeted interventions to improve participation rates within priority populations.

METHODS

PubMed, Embase, Scopus, Cinahl and PsycInfo were systematically searched from inception to 22 June 2022. Eligible studies contained qualitative evidence identifying barriers to FOBT based CRC screening for populations impacted by the social determinants of health. An inductive thematic synthesis approach was applied using grounded theory methodology, to explore descriptive themes and interpret these into higher order analytical constructs and theories.

RESULTS

A total of 8,501 publications were identified and screened. A total of 48 studies from 10 countries were eligible for inclusion, representing 2,232 subjects. Coding within included studies resulted in 30 key descriptive themes with a thematic frequency greater than 10%. Coded themes applied to four overarching, interconnected barriers driving inequality for priority populations: social, behavioural, economic and technical/interfaces. SO WHAT?: This study has highlighted the need for stronger patient/provider relationships to mitigate barriers to FOBT screening participation for diverse groups. Findings can assist health professionals and policy makers address the systemic exclusion of priority populations in cancer screening by moving beyond the responsibility of the individual to a focus on addressing the information asymmetry driving low value perceptions.

Video brochures in a mailed fecal immunochemical test outreach program provide cancer screening information in a user-friendly format for rural Appalachian community members

PURPOSE

Colorectal cancer (CRC) screening is recommended for average-risk adults, yet many adults are not up-to-date with screening. One recommended CRC screening approach is the annual completion of a fecal immunochemical test (FIT). However, usually, fewer than half of mailed FIT tests are returned.

METHODS

To address barriers to FIT return, a video brochure was developed providing targeted CRC screening information and step-by-step FIT instructions as a component in a mailed FIT program. This pilot study occurred in 2021-2022 and partnered with a federally qualified health center in Appalachian Ohio to send a FIT to patients who were 50-64 years old, of average risk, and not up-to-date on CRC screening. Patients were randomly assigned to 1 of 3 groups that differed on materials sent with the FIT: usual care (manufacturer's instructions), a video brochure (video instructions, disposable gloves, disposable stool collection device), or an audio brochure (audio instructions, disposable gloves, disposable stool collection device).

FINDINGS

Overall, 16 of 94 patients (17%) returned the FIT, and return was higher among those sent the video brochure (28%) compared to the other 2 groups (OR: 3.1; 95% CI: 1.02, 9.2; P = .046). Two patients had positive tests and were referred for colonoscopy. Patients sent the video brochure reported the content was important, relevant, and made them think about completing the FIT.

CONCLUSIONS

Using a video brochure to provide understandable information in a mailed FIT kit is a promising strategy to improve CRC screening outreach programs in rural regions.

Reach and effectiveness of a centralized navigation program for patients with positive fecal immunochemical tests requiring follow-up colonoscopy

Completion rates for follow-up colonoscopies after an abnormal fecal immunochemical test (FIT) are suboptimal in federally qualified health center (FQHC) settings. We implemented a screening intervention that included mailed FIT outreach to North Carolina FQHC patients from June 2020 to September 2021 and centralized patient navigation to support patients with abnormal FITs in completing follow-up colonoscopy. We evaluated the reach and effectiveness of navigation using electronic medical record data and navigator call logs detailing interactions with patients. Reach assessments included the proportion of patients successfully contacted by phone and who agreed to participate in navigation, intensity of navigation provided (including types of barriers to colonoscopy identified and total navigation time), and differences in these measures by socio-demographic characteristics. Effectiveness outcomes included colonoscopy completion, timeliness of follow-up colonoscopy (i.e., within 9 months), and bowel prep adequacy. Among 514 patients who completed a mailed FIT, 38 patients had an abnormal result and were eligible for navigation. Of these, 26 (68%) accepted navigation, 7 (18%) declined, and 5 (13%) could not be contacted. Among navigated patients, 81% had informational needs, 38% had emotional barriers, 35% had financial barriers, 12% had transportation barriers, and 42% had multiple barriers to colonoscopy. Median navigation time was 48.5 min (range: 24-277 min). Colonoscopy completion differed across groups - 92% of those accepting navigation completed colonoscopy within 9 months, versus 43% for those declining navigation. We found that centralized navigation was widely accepted in FQHC patients with abnormal FIT, and was an effective strategy, resulting in high colonoscopy completion rates.

A "sludge audit" for health system colorectal cancer screening services

OBJECTIVES

"Sludge," or the frictions or administrative burdens that make it difficult for people to attain what they want or need, is an unexplored health care delivery factor that may contribute to deficiencies in colorectal cancer (CRC) screening. We piloted a method to identify and quantify sludge in a southeastern US health system's delivery of CRC screening services.

STUDY DESIGN

Mixed methods sludge audit.

METHODS

We collected and analyzed quantitative (insurance claims, electronic health record, and administrative files) and qualitative (stakeholder interviews and process observations) data associated with CRC screening for instances of sludge. Because they contribute to sludge and reduce system capacity for high-value screening, we also evaluated low-value CRC screening processes.

RESULTS

Although specific results were likely amplified by effects of the COVID-19 pandemic, the sludge audit revealed important areas for improvement. A 60.4% screening rate was observed. Approximately half of screening orders were not completed. The following categories of sludge were identified: communication, time, technology, administrative tasks, paperwork, and low-value care. For example, wait times for screening colonoscopy were substantial, duplicate orders were common, and some results were not accessible in the electronic health record. Of completed screenings, 32% were low-value and 38% were associated with low-value preoperative testing. There was evidence of a differential negative impact of sludge to vulnerable patients.

CONCLUSIONS

Our sludge audit method identified and quantified multiple instances of sludge in a health system's CRC screening processes. Sludge audits can help organizations to systematically evaluate and reduce sludge for more effective and equitable CRC screening.

Cancer Screening Among Rural and Urban Clinics During COVID-19: A Multistate Qualitative Study

PURPOSE

The effects of COVID-19 have been understudied in rural areas. This study sought to (1) identify cancer screening barriers and facilitators during the pandemic in rural and urban primary care practices, (2) describe implementation strategies to support cancer screening, and (3) provide recommendations.

METHODS

A qualitative study was conducted (N = 42) with primary care staff across 20 sites. Individual interviews were conducted through videoconference from August 2020 to April 2021 and recorded, transcribed, and analyzed using deductive and inductive coding (hybrid approach) in NVivo 12 Plus. Practices included federally qualified health centers, tribal health centers, rural health clinics, hospital/health system-owned clinics, and academic medical centers across 10 states including urban (55%) and rural (45%) sites. Staff included individuals serving in the dual role of health care provider and administrator (21.4%), health care administrator (23.8%), physician (19.0%), advanced practice provider (11.9%), or resident (23.8%). The interviews assessed perceptions about cancer screening barriers and facilitators, implementation strategies, and future recommendations.

RESULTS

Participants reported multilevel barriers to cancer screening including policy-level (eg, elective procedure delays), organizational (eg, backlogs), and individual (eg, patient cancellation). Several facilitators to screening were noted, such as home-based testing, using telehealth, and strong partnerships with referral sites. Practices used strategies to encourage screening, such as incentivizing patients and providers and expanding outreach. Rural clinics reported challenges with backlogs, staffing, telehealth implementation, and patient outreach.

CONCLUSION

Primary care staff used innovative strategies during the pandemic to promote cancer screening. Unresolved challenges (eg, backlogs and inability to implement telehealth) disproportionately affected rural clinics.

Improving Fecal Immunochemical Test Return Rates: A Colorectal Cancer Screening Quality Improvement Project in a Multisite Federally Qualified Health Center

The goal of this quality improvement project was to improve colorectal cancer (CRC) screening rates in a multicenter federally qualified health center (FQHC) within the Central Appalachian region of rural, southwestern Virginia. Guided by the Plan-Do-Study-Act (PDSA) cycle, the objectives were to (1) evaluate implementation processes and effectiveness of an automated electronic medical record patient reminder system to promote fecal immunochemical test (FIT) completion, compared with live telephone reminders delivered by a care coordinator (i.e., usual care), and (2) explore staff perceptions related to improving CRC screening rates. In total, 119 FITs were distributed with 59 assigned to usual care and 60 to the automated groups. In the usual care group, 79% patients with completed protocol returned their FIT; 9% were positive. In the automated reminder group, 76% patients with completed protocol returned their FIT; 10% were positive. There was no significant difference in the number of contacts per patients between the usual care (2.0, SD = 0.82 contacts/patient) and automated (1.8, SD = 0.98 contacts/patient) groups (p = .248). In total, the usual care and automated groups required 56 and 17 live calls, respectively. Overall, FQHC system-wide CRC screening rates increase from 30.5% to 47.3%. Ten staff interviews revealed perceptions of CRC screening, the QI project, and organizational change processes that may inform future cancer control projects. Researcher and practitioners should consider PDSA quality improvement projects as an initial step to build capacity and improve CRC screening rates, especially when working in FQHC with limited resources to engage in large complex research projects.

Perspectives of cancer prevention and control resources from stakeholders in rural southern Illinois

PURPOSE

Rural residents have a higher cancer burden than urban residents, which is likely related to multiple socioecological factors. This study sought to investigate the perspectives of a diverse set of rural stakeholders regarding access to cancer prevention and control resources in rural southern Illinois.

METHODS

Stakeholders were recruited from counties in southern Illinois and included residents (cancer survivors or caregivers), leaders of community-based organizations with health-related missions, and health care providers. Individual interviews and focus groups assessed recommended cancer prevention, control, and treatment resources; helpfulness of regional resources; and needed resources. The research team used an iterative approach to thematic analysis wherein codes were derived inductively and refined repeatedly to reveal overarching themes.

FINDINGS

Forty-four stakeholders reported challenges to health care access (eg, travel distance, financial burdens, and poor quality of care) and limited access to supportive care services (lack of caregiver support and "spotty" area resources). To mitigate these barriers, local residents used a combination of individual (self-reliance and adaptive measures) and organizational (patient navigation and financial services) approaches. Finally, stakeholders reported multiple forms of cancer control and prevention communication, including formal discussions with health care providers and various types of informal social support (eg, friends and family).

CONCLUSIONS

Stakeholders experienced barriers to cancer prevention and control often mitigated by a reliance on personal adaptations, nonclinical organizational supports, and informal support systems. While resources remain minimal in southern Illinois, researchers and practitioners must make efforts to leverage existing community organizations and social networks to improve cancer outcomes in this region.

Advancing engagement and capacity for rural cancer control: a mixed-methods case study of a Community-Academic Advisory Board in the Appalachia region of Southwest Virginia

BACKGROUND

The objectives are to: 1) describe engagement processes used to prioritize and address regional comprehensive cancer control needs among a Community-Academic Advisory Board (CAB) in the medically-underserved, rural Appalachian region, and 2) detail longitudinal CAB evaluation findings.

METHODS

This three-year case study (2017-2020) used a convergent parallel, mixed-methods design. The approach was guided by community-based participatory research (CBPR) principles, the Comprehensive Participatory Planning and Evaluation process, and Nine Habits of Successful Comprehensive Cancer Control Coalitions. Meeting artifacts were tracked and evaluated. CAB members completed quantitative surveys at three time points and semi-structured interviews at two time points. Quantitative data were analyzed using analysis of variance tests. Interviews were audio recorded, transcribed, and analyzed via an inductive-deductive process.

RESULTS

Through 13 meetings, Prevention and Early Detection Action Teams created causal models and prioritized four cancer control needs: human papillomavirus vaccination, tobacco control, colorectal cancer screening, and lung cancer screening. These sub-groups also began advancing into planning and intervention proposal development phases. As rated by 49 involved CAB members, all habits significantly improved from Time 1 to Time 2 (i.e., communication, priority work plans, roles/accountability, shared decision making, value-added collaboration, empowered leadership, diversified funding, trust, satisfaction; all p < .05), and most remained significantly higher at Time 3. CAB members also identified specific challenges (e.g., fully utilizing member expertise), strengths (e.g., diverse membership), and recommendations across habits.

CONCLUSION

This project's equity-based CBPR approach used a CPPE process in conjunction with internal evaluation of cancer coalition best practices to advance CAB efforts to address cancer disparities in rural Appalachia. This approach encouraged CAB buy-in and identified key strengths, weaknesses, and opportunities that will lay the foundation for continued involvement in cancer control projects. These engagement processes may serve as a template for similar coalitions in rural, underserved areas.
