Barriers and Facilitators of Colorectal Cancer Screening for Patients of Rural Accountable Care Organization Clinics: A Multilevel Analysis

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.

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

PURPOSE

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Evaluating variations in the barriers to colorectal cancer screening associated with telehealth use in rural U.S. Pacific Northwest

PURPOSE

The incidence and mortality rates of colorectal cancer (CRC) remain consistently high in rural populations. Telehealth can improve screening uptake by overcoming individual and environmental disadvantages in rural communities. The present study aimed to characterize varying barriers to CRC screening between rural individuals with and without experience in using telehealth.

METHOD

The cross-sectional study surveyed 250 adults aged 45-75 residing in rural U.S. states of Alaska, Idaho, Oregon, and Washington from June to September 2022. The associations between CRC screening and four sets of individual and environmental factors specific to rural populations (i.e., demographic characteristics, accessibility, patient-provider factors, and psychological factors) were assessed among respondents with and without past telehealth adoption.

RESULT

Respondents with past telehealth use were more likely to screen if they were married, had a better health status, had experienced discrimination in health care, and had perceived susceptibility, screening efficacy, and cancer fear, but less likely to screen when they worried about privacy or had feelings of embarrassment, pain, and discomfort. Among respondents without past telehealth use, the odds of CRC screening decreased with busy schedules, travel burden, discrimination in health care, and lower perceived needs.

CONCLUSION

Rural individuals with and without previous telehealth experience face different barriers to CRC screening. The finding suggests the potential efficacy of telehealth in mitigating critical barriers to CRC screening associated with social, health care, and built environments of rural communities.

Cross-sectional survey study of primary care clinics on evidence-based colorectal cancer screening intervention use

PURPOSE

The purpose of this study was to examine differences between urban and rural primary care clinics in the use of colorectal cancer (CRC) screening methods and evidence-based interventions to promote CRC screening.

METHODS

This was a cross-sectional survey of primary care clinics in Nebraska. Surveys in paper form were sent out and followed up with telephone interviews to nonrespondents. Of the 375 facilities, 263 (70.1%) responded to the survey.

FINDINGS

Over 30% of urban clinics indicated that 80% or more of their patients were meeting the CRC guidelines compared to 18.3% of rural clinics (P = .03). Rural clinics were more likely than urban clinics to prefer the use of colonoscopy alone or in combination with stool tests (P = .02). The most common interventions for CRC screening included one-on-one patient education and use of computer-based pop-ups to remind providers.

CONCLUSIONS

In conclusion, we found some important differences between rural and urban primary care clinics in the implementation of CRC screening. Given that there is evidence for differences in preference for CRC screening methods (colonoscopy vs stool-based tests) between rural and urban community members, it is important to assess the effectiveness of different types of CRC screening interventions by comparing rural and urban primary care clinic patient populations.

Effect of inpatient breast cancer education and risk assessment on mammography utilization among hospitalized women post discharge

OBJECTIVE

To evaluate prevalence of nonadherence to breast cancer screening guidelines after bedside educational intervention and informed individualized risk assessment score during an inpatient stay.

METHODS

A prospective intervention study was conducted among 507 cancer-free (except skin cancer) women aged 50-75 years hospitalized to a general medicine service. Study intervention included one-on-one bedside education via handout and videos about breast cancer screening and informed individualized risk assessment using the Gail risk model to predict 5-year risk for breast cancer development. Study outcomes were measured using posthospitalization follow-up survey to determine if intervention resulted in improved adherence to breast cancer screening. Chi-square and unpaired t-tests were utilized to compare population characteristics.

RESULTS

The mean age for the study population was 60.5 years (SD = 6.9), the mean 5-year Gail risk score was 1.77 (SD = 1), and 36% of women were African American. One hundred sixty nine (33%) hospitalized women were nonadherent to breast cancer screening recommendations. Only 15% of the nonadherent women were reachable for follow-up survey, and 42% of these women self-reported adherence to screening mammography after a mean follow-up period of 27 months.

CONCLUSION

This study provides evidence that most women who are nonadherent to breast cancer screening remain nonadherent after hospital discharge despite educational interventions. Our study intervention was only partially successful in enhancing breast cancer screening among hospitalized women who were overdue and at high risk. Further studies need to evaluate strategies to overcome the barriers and improve adherence whenever patients encounter health care system regardless of clinical locale.

Reaching Rural Residents to Identify Colorectal Cancer Education and Intervention Targets

Disparities in cancer screening and care in rural communities warrant the need to determine effective ways to reach, engage, and educate the community residents. The purpose of this cross-sectional study was to pilot methods to engage rural residents in colorectal cancer (CRC) research and education activities and assess knowledge of CRC guidelines, symptoms, and screening behaviors in this sample. The community-engaged research approach was employed to develop and distribute a CRC knowledge and screening behavior assessment using various methods such as email and community drop boxes placed throughout the community. Bivariate analysis assessed the relationship between age and CRC knowledge items. Three hundred ninety-one surveys were returned with most received from community drop boxes (60%) followed by educational events (23%). The most ineffective method to distribute surveys was through community events. Most individuals were knowledgeable of CRC symptoms (70%) and screening facts (67%). Bivariate analysis showed that individuals 50 years or older had significantly more knowledge of CRC risks and screening than those under the age of 50. This study highlights the potential of community drop boxes as an effective method for engaging rural communities. Further, findings from the survey highlight the need to focus CRC education on younger individuals in which CRC incidence has increased.

Colorectal Cancer Screening Uptake: Differences Between Rural and Urban Privately-Insured Population

Earlier studies investigated rural-urban colorectal cancer (CRC) screening disparities among older adults or used surveys. The objective was to compare screening uptake between rural and urban individuals 50–64 years of age using private health insurance. Data were analyzed from 58,774 Blue Cross Blue Shield of Nebraska beneficiaries. Logistic regression was used to assess the association between rural-urban and CRC screening use. Results indicate that rural individuals were 56% more likely to use the Fecal Occult Blood Test (FOBT) compared with urban residents, but rural females were 68% less likely to use FOBT. Individuals with few Primary Care Physician (PCP) visits and rural-women are the least to receive screening. To enhance CRC screening, a policy should be devised for the training and placement of female PCP in rural areas. In particular, multilevel interventions, including education, more resources, and policies to increase uptake of colorectal cancer screening, are needed. Further research is warranted to investigate barriers to CRC screening in rural areas.

An Examination of Multilevel Factors Influencing Colorectal Cancer Screening in Primary Care Accountable Care Organization Settings: A Mixed-Methods Study

OBJECTIVE

To identify patient, provider, and delivery system-level factors associated with colorectal cancer (CRC) screening and validate findings across multiple data sets.

DESIGN

A concurrent mixed-methods design using electronic health records, provider survey, and provider interview.

SETTING

Eight primary care accountable care organization clinics in Nebraska.

MEASURES

Patients' demographic/social characteristics, health utilization behaviors, and perceptions toward CRC screening; provider demographics and practice patterns; and clinics' delivery systems (eg, reminder system).

ANALYSIS

Quantitative (frequencies, logistic regression, and t tests) and qualitative analyses (thematic coding).

RESULTS

At the patient level, being 65 years of age and older (odds ratio [OR] = 1.34, P < .001), being non-Hispanic white (OR = 1.93, P < .001), having insurance (OR = 1.90, P = .01), having an annual physical examination (OR = 2.36, P < .001), and having chronic conditions (OR = 1.65 for 1-2 conditions, P < .001) were associated positively with screening, compared with their counterparts. The top 5 patient-level barriers included discomfort/pain of the procedure (60.3%), finance/cost (57.4%), other priority health issues (39.7%), lack of awareness (36.8%), and health literacy (26.5%). At the provider level, being female (OR = 1.88, P < .001), having medical doctor credentials (OR = 3.05, P < .001), and having a daily patient load less than 15 (OR = 1.50, P = .01) were positively related to CRC screening. None of the delivery system factors were significant except the reminder system. Interview data provided in-depth information on how these factors help or hinder CRC screening. Discrepancies in findings were observed in chronic condition, colonoscopy performed by primary doctors, and the clinic-level system factors.

CONCLUSIONS

This study informs practitioners and policy makers on the effective multilevel strategies to promote CRC screening in primary care accountable care organization or equivalent settings. Some inconsistent findings between data sources require additional prospective cohort studies to validate those identified factors in question. The strategies may include (1) developing programs targeting relatively younger age groups or racial/ethnic minorities, (2) adapting multilevel/multicomponent interventions to address low demands and access of local population, (3) promoting annual physical examination as a cost-effective strategy, and (4) supporting organizational capacity and infrastructure (eg, IT system) to facilitate implementation of evidence-based interventions.

Assessing adherence and cost-benefit of colorectal cancer screening for accountable providers

The objective of this study was to assess adherence and costs-benefits of colorectal cancer (CRC) screenings from an accountable care organization/population health perspective. We performed a retrospective review of 94 patients (50-75 years of age) in an integrated safety net system for whom fecal CRC screening was abnormal for the period of June 1, 2014, to June 1, 2016. A cost-benefit model was constructed using Medicare payment rates and a sensitivity analysis. Most patients included in the study (64/94, 68%) received or were offered a colonoscopy. Of those receiving a colonoscopy, 24 of 45 (53%) had an abnormal finding. Total direct medical costs avoided by screening the patient panel was $32,926 but could have exceeded $63,237 had more patients received follow-up colonoscopies. A sensitivity analysis with 1000 patients demonstrated total monetary benefits between $2.2 million and $8.16 million when follow-up and colonoscopy rates were allowed to vary. Although the resulting rates of follow-up were within the range reported in the literature, there is room for improvement, especially considering the monetary benefit that could be used on other diseases. Health systems and payers should work cooperatively to structure payment models to better incentivize CRC screenings.

Key Collaborative Factors When Medicaid Accountable Care Organizations Work With Primary Care Clinics to Improve Colorectal Cancer Screening: Relationships, Data, and Quality Improvement Infrastructure

Purpose

Accountable Care Organizations (ACOs) are implementing interventions to achieve triple-aim objectives of improved quality and experience of care while maintaining costs. Partnering across organizational boundaries is perceived as critical to ACO success.

Methods

We conducted a comparative case study of 14 Medicaid ACOs in Oregon and their contracted primary care clinics using public performance data, key informant interviews, and consultation field notes. We focused on how ACOs work with clinics to improve colorectal cancer (CRC) screening — one incentivized performance metric.

Results

ACOs implemented a broad spectrum of multi-component interventions designed to increase CRC screening. The most common interventions focused on reducing structural barriers (n = 12 ACOs), delivering provider assessment and feedback (n = 11), and providing patient reminders (n = 7). ACOs developed their processes and infrastructure for working with clinics over time. Facilitators of successful collaboration included a history of and commitment to collaboration (partnership); the ability to provide accurate data to prioritize action and monitor improvement (performance data), and supporting clinics’ reflective learning through facilitation, learning collaboratives; and support of ACO as well as clinic-based staffing (quality improvement infrastructure). Two unintended consequences of ACO–clinic partnership emerged: potential exclusion of smaller clinics and metric focus and fatigue.

Conclusion

Our findings identified partnership, performance data, and quality improvement infrastructure as critical dimensions when Medicaid ACOs work with primary care to improve CRC screening. Findings may extend to other metric targets.

Colorectal cancer screening in newly insured Medicaid members: a review of concurrent federal and state policies

BACKGROUND

Colorectal cancer (CRC) screening is underutilized by Medicaid enrollees and the uninsured. Multiple national and state policies were enacted from 2010 to 2014 to increase access to Medicaid and to promote CRC screening among Medicaid enrollees. We aimed to determine the impact of these policies on screening initiation among newly enrolled Oregon Medicaid beneficiaries age-eligible for CRC screening.

METHODS

We identified national and state policies affecting Medicaid coverage and preventive services in Oregon during 2010-2014. We used Oregon Medicaid claims data from 2010 to 2015 to conduct a cohort analysis of enrollees who turned 50 and became age-eligible for CRC screening (a prevention milestone, and an age at which guideline-concordant screening can be assessed within a single year) during each year from 2010 to 2014. We calculated risk ratios to assess whether first year of Medicaid enrollment and/or year turned 50 was associated with CRC screening initiation.

RESULTS

We identified 14,576 Oregon Medicaid enrollees who turned 50 during 2010-2014; 2429 (17%) completed CRC screening within 12 months after turning 50. Individuals newly enrolled in Medicaid in 2013 or 2014 were 1.58 and 1.31 times more likely, respectively, to initiate CRC screening than those enrolled by 2010. A primary care visit in the calendar year, having one or more chronic conditions, and being Hispanic was also associated with CRC screening initiation.

DISCUSSION

The increased uptake of CRC screening in 2013 and 2014 is associated with the timing of policies such as Medicaid expansion, enhanced federal matching for preventive services offered to Medicaid enrollees without cost sharing, and formation of Medicaid accountable care organizations, which included CRC screening as an incentivized quality metric.

Does a transition to accountable care in Medicaid shift the modality of colorectal cancer testing?

BACKGROUND

Health care reform is changing preventive services delivery. This study explored trajectories in colorectal cancer (CRC) testing over a 5-year period that included implementation of 16 Medicaid Accountable Care Organizations (ACOs, 2012) and Medicaid expansion (2014) - two provisions of the Affordable Care Act (ACA) - within the state of Oregon, USA.

METHODS

Retrospective analysis of Oregon's Medicaid claims for enrollee's eligible for CRC screening (50-64 years) spanning January 2010 through December 2014. Our analysis was conducted and refined April 2016 through June 2018. The analysis assessed the annual probability of patients receiving CRC testing and the modality used (e.g., colonoscopy, fecal testing) relative to a baseline year (2010). We hypothesized that CRC testing would increase following Medicaid ACO formation - called Coordinated Care Organizations (CCOs).

RESULTS

A total of 132,424 unique Medicaid enrollees (representing 255,192 person-years) met inclusion criteria over the 5-year study. Controlling for demographic and regional factors, the predicted probability of CRC testing was significantly higher in 2014 (+ 1.4 percentage points, p < 0.001) compared to the 2010 baseline but not in 2012 or 2013. Increased fecal testing using Fecal Occult Blood Tests (FOBT) or Fecal Immunochemical Tests (FIT) played a prominent role in 2014. The uptick in statewide fecal testing appears driven primarily by a subset of CCOs.

CONCLUSIONS

Observed CRC testing did not immediately increase following the transition to CCOs in 2012. However increased testing in 2014, may reflect a delay in implementation of interventions to increase CRC screening and/or a strong desire by newly insured Medicaid CCO members to receive preventive care.

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

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

Effect of childhood socioeconomic conditions on cancer onset in later life: an ambidirectional cohort study

Objectives

Living in low socioeconomic conditions during childhood is associated with poor health outcomes in later life. Whether this link also applies to cancer is unclear. We examined whether childhood socioeconomic conditions (CSCs) are associated with cancer risk in later life and whether this effect remained after adjusting for adulthood socioeconomic conditions (ASCs).

Methods

Data for 26,431 individuals ≥ 50 years old included in SHARE were analysed. CSCs were constructed by using indicators of living conditions at age 10. ASC indicators were education, main occupation, and household income. Gender-stratified associations of CSCs with cancer onset (overall and by site) were assessed by Cox regression.

Results

In total, 2852 individuals were diagnosed with cancer. For both men and women, risk of overall cancer was increased for advantaged CSCs and remained so after adjusting for ASCs (hazard ratio = 1.36, 95% CI 1.10, 1.63, and 1.70, 95% CI 1.41, 2.07).

Conclusions

Advantaged CSCs are associated with an increased risk of overall cancer at older age, but results vary by cancer sites and sex. Participation in cancer screening or exposure to risk factors may differ by social conditions.

Breast Cancer Screening for Patients of Rural Accountable Care Organization Clinics: A Multi-Level Analysis of Barriers and Facilitators

Not all women 50-74 years received biennial mammography and the situation is worse in rural areas. Accountable care organizations (ACO) emphasize coordinated care, use of electronic health system, and preventive quality measures and these practices may improve their patients' breast cancer screening rate. Using medical record data of 8,347 women patients aged 50-74 years from eight rural ACO clinics in Nebraska, this study examined patient-, provider-, and county-level barriers and facilitators for breast cancer screening. A generalized estimating equations model was used to account for the correlation among patients from the same provider and county. The multi-level logistic regression results suggest that uninsured non-Hispanic Black patients were less likely to meet the biennial mammography screening guideline. Patients whose preferred language being English, having a preventive visit in the past 12 months, having one or more chronic conditions were more likely to meet the biennial mammography screening guideline. Patients with a primary care provider (PCP) that was male, without a medical doctor degree were less likely to screen biennially. Patients with a PCP that reviewed performance report quarterly, or manually checked patients' mammography screening status during visits were more likely to screen biennially. Interestingly, patients whose PCP reported being reminded by a care coordination team were less likely to screen biennially. Patients living in counties with more PCPs were also more likely to screen biennially. The study findings suggest that efforts targeting individual and practice-level barriers could be most effective in improving mammography screening for these rural ACO patients.
