Distance and Transportation Barriers to Colorectal Cancer Screening in a Rural Community

Predictors of Colorectal Cancer Screening and Screening Modalities among Patients seen at Federally Qualified Health Centers Funded by the United States Health Resources and Services Administration

Introduction

Federally qualified health centers provide primary care services to millions of low-income patients in the United States who face challenges accessing colorectal cancer (CRC) screening. We aimed to understand how patient-level factors influence CRC screening participation and screening modality choice in this setting.

Methods

We examined data from the 2022 Health Center Patient Survey, 2021 Uniform Data System, and Area Health Resource File. We performed generalized multilevel logistic regression and multinomial regression to measure associations between our independent variables and receipt of any CRC screening and of screening modalities.

Results

Among 1584 patients ages 50-75, most (56 %) reported having CRC screening, including 33 % with endoscopic screening only, 16 % with stool-based screening only, and 7 % with multiple modalities. Selected factors associated with any CRC screening included having five or more health center visits in the past year (aOR = 1.66, 95 %CI = 1.07-2.56), being insured (Medicaid aOR = 2.25, 95 %CI = 1.44-3.54; other insurance aOR = 2.69, 95 %CI = 1.51-4.82), living within 30  minutes of the health center (aOR = 1.93, 95 %CI = 1.15-3.25), having multiple comorbidities (aOR = 1.72, 95 %CI = 1.13-2.63), using telehealth (aOR = 1.52, 95 %CI = 1.02-2.27), and having a flu shot last year (aOR = 1.77, 95 %CI = 1.29-2.45). We observed that patients who are non-Hispanic Black (aOR = 3.52, 95 %CI = 1.28-9.68) and who do not speak English well or at all (aOR = 5.54, 95 %CI = 1.64-18.75) reported having multiple modalities.

Conclusion

Federally qualified health center patients reported endoscopic CRC screening more commonly than stool-based screening, and barriers to access such as distance to the health center and English proficiency were impactful. Increasing CRC screening in low-income populations requires improving access and promoting opportunities for less invasive screening.

Promising Cellular Immunotherapy for Colorectal Cancer Using Classical Dendritic Cells and Natural Killer T Cells

Colorectal cancer (CRC) remains one of the leading causes of cancer-related morbidity and mortality around the world. Despite advances in surgery, chemotherapy, and targeted therapies, the prognosis for patients with metastatic or advanced CRC remains poor. Immunotherapies comprising immune checkpoint inhibitors showed disappointing responses in metastatic CRC (mCRC). However, cellular immunotherapy, specifically using classical dendritic cells (cDCs), may hold unique promise in immune recognition for CRC antigens. cDCs are substantial players in immune recognition and are instrumental in orchestrating innate and adaptive immune responses by processing and presenting tumor antigens to effector cells. Natural killer T (NKT) cells are insufficiently studied but unique effector cells because of their ability to bridge innate and adaptive immune reactions and the crosstalk with dendritic cells in cancer. This review explores the therapeutic potential of using both cDCs and NKT cells as a synergistic therapy in CRC, focusing on their biological roles, strategies for harnessing their capabilities, clinical applications, and the challenges within the tumor microenvironment. Both cDCs and NKT cells can be used as a new effective approach for cell-based therapies in cancers to provide a new hope for CRC patients that are challenging to treat.

Inequities in childhood cancer research: A scoping review

An integral part of understanding and then designing programs to reduce childhood cancer inequities includes adequate representation of people with cancer in research, including children. A scoping review was carried out to understand how cancer research is oriented toward inequities and to identify who has participated in childhood qualitative cancer research. A systematic search identified 119 qualitative studies that met inclusion criteria, with most studies taking place in high-income countries (n=84). Overall, data were lacking on social determinants of health at multiple levels-structural, household, child, and guardian. Only 29 studies reported on race and/or ethnicity, with the majority of those including predominantly or all white children. Six articles included socioeconomic information, and across most articles, attention was absent to the financial ramifications of cancer care. Limited reporting of sociodemographics highlights a broader issue of neglecting key demographics and social factors that contribute to inequities.

Effects of Medicaid managed care on early detection of cancer: Evidence from mandatory Medicaid managed care program in Pennsylvania

OBJECTIVE

To examine changes in late- versus early-stage diagnosis of cancer associated with the introduction of mandatory Medicaid managed care (MMC) in Pennsylvania.

DATA SOURCES AND STUDY SETTING

We analyzed data from the Pennsylvania cancer registry (2010-2018) for adult Medicaid beneficiaries aged 21-64 newly diagnosed with a solid tumor. To ascertain Medicaid and managed care status around diagnosis, we linked the cancer registry to statewide hospital-based facility records collected by an independent state agency (Pennsylvania Health Care Cost Containment Council).

STUDY DESIGN

We leveraged a natural experiment arising from county-level variation in mandatory MMC in Pennsylvania. Using a stacked difference-in-differences design, we compared changes in the probability of late-stage cancer diagnosis among those residing in counties that newly transitioned to mandatory managed care to contemporaneous changes among those in counties with mature MMC programs.

DATA COLLECTION/EXTRACTION METHODS

N/A.

PRINCIPAL FINDINGS

Mandatory MMC was associated with a reduced probability of late-stage cancer diagnosis (-3.9 percentage points; 95% CI: -7.2, -0.5; p = 0.02), particularly for screening-amenable cancers (-5.5 percentage points; 95% CI: -10.4, -0.6; p = 0.03). We found no significant changes in late-stage diagnosis among non-screening amenable cancers.

CONCLUSIONS

In Pennsylvania, the implementation of mandatory MMC for adult Medicaid beneficiaries was associated with earlier stage of diagnosis among newly diagnosed cancer patients with Medicaid, especially those diagnosed with screening-amenable cancers. Considering that over half of the sample was diagnosed with late-stage cancer even after the transition to mandatory MMC, Medicaid programs and managed care organizations should continue to carefully monitor receipt of cancer screening and design strategies to reduce barriers to guideline-concordant screening or diagnostic procedures.

Colonoscopy Outreach for Rural Communities (CORC): A study protocol of a pragmatic randomized controlled trial of a patient navigation program to improve colonoscopy completion for colorectal cancer screening

BACKGROUND

Colonoscopy is one of the primary methods of screening for colorectal cancer (CRC), a leading cause of cancer mortality in the United States. However, up to half of patients referred to colonoscopy fail to complete the procedure, and rates of adherence are lower in rural areas.

OBJECTIVES

Colonoscopy Outreach for Rural Communities (CORC) is a randomized controlled trial to test the effectiveness of a centralized patient navigation program provided remotely by a community-based organization to six geographically distant primary care organizations serving rural patients, to improve colonoscopy completion for CRC.

METHODS

CORC is a type 1 hybrid implementation-effectiveness trial. Participants aged 45-76 from six primary care organizations serving rural populations in the northwestern United States are randomized 1:1 to patient navigation or standard of care control. The patient navigation is delivered remotely by a trained lay-person from a community-based organization. The primary effectiveness outcome is completion of colonoscopy within one year of referral to colonoscopy. Secondary outcomes are colonoscopy completion within 6 and 9 months, time to completion, adequacy of patient bowel preparation, and achievement of cecal intubation. Analyses will be stratified by primary care organization.

DISCUSSION

Trial results will add to our understanding about the effectiveness of patient navigation programs to improve colonoscopy for CRC in rural communities. The protocol includes pragmatic adaptations to meet the needs of rural communities and findings may inform approaches for future studies and programs.

Participatory action research to develop and implement multicomponent, multilevel strategies for implementing colorectal cancer screening interventions in American Indian communities in New Mexico

BACKGROUND

Despite the effectiveness of colorectal cancer (CRC) screening, American Indians (AIs) have low screening rates in the US. Many AIs receive care at Indian Health Services, Tribal, and Urban Indian (I/T/U) healthcare facilities, where published evidence regarding the implementation of CRC screening interventions is lacking. To address this gap, the University of New Mexico Comprehensive Cancer Center and the Albuquerque Area Southwest Tribal Epidemiology Center collaborated with two tribally-operated healthcare facilities in New Mexico with the goal of improving CRC screening rates among New Mexico's AI communities.

METHODS

Guided by the principles of Community Based Participatory Research, we engaged providers from the two tribal healthcare facilities and tribal community members through focus group (two focus groups with providers (n = 15) and four focus group and listening sessions with community members (n = 65)), to elicit perspectives on the feasibility and appropriateness of implementing The Guide to Community Preventive Services (The Community Guide) recommended evidence-based interventions (EBIs) and strategies for increasing CRC screening. Within each tribal healthcare facility, we engaged a Multisector Action Team (MAT) that participated in an implementation survey to document the extent to which their healthcare facilities were implementing EBIs and strategies, and an organizational readiness survey that queried whether their healthcare facilities could implement additional strategies to improve uptake of CRC screening.

RESULTS

The Community Guide recommended EBIs and strategies that received the most support as feasible and appropriate from community members included: one-on-one education from providers, reminders, small media, and interventions that reduced structural barriers. From the providers' perspective, feasible and acceptable strategies included one-on-one education, patient and provider reminders, and provider assessment and feedback. Universally, providers mentioned the need for patient navigators who could provide culturally appropriate education about CRC and assist with transportation, and improved support for coordinating clinical follow-up after screening. The readiness survey highlighted overall readiness of the tribal facility, while the implementation survey highlighted that few strategies were being implemented.

CONCLUSIONS

Findings from this study contribute to the limited literature around implementation research at tribal healthcare facilities and informed the selection of specific implementation strategies to promote the uptake of CRC screening in AI communities.

The impact of transportation mode, socioeconomic deprivation and rurality on travel times to radiotherapy and surgical services for patients with prostate cancer: A national population-based evaluation

BACKGROUND

The distances that patients have to travel can influence their access to cancer treatment. We investigated the determinants of travel time, separately for journeys by car and public transport, to centres providing radical surgery or radiotherapy for prostate cancer.

METHODS

Using national cancer registry records linked to administrative hospital data, we identified patients who had radical surgery or radiotherapy for prostate cancer between January 2017 and December 2018 in the English National Health Service. Estimated travel times from the patients' residential area to the nearest specialist surgical or radiotherapy centre were estimated for journeys by car and by public transport.

RESULTS

We included 13,186 men who had surgery and 26,581 who had radiotherapy. Estimated travel times by public transport (74.4 mins for surgery and 69.4 mins for radiotherapy) were more than twice as long as by car (33.4 mins and 29.1mins, respectively). Patients living in more socially deprived neighbourhoods in rural areas had the longest travel times to the nearest cancer treatment centres by car (62.0 mins for surgery and 52.1 mins for radiotherapy). Conversely patients living in more affluent neighbourhoods in urban conurbations had the shortest (18.7 mins for surgery and 17.9 mins for radiotherapy).

CONCLUSION

Travel times to cancer centres vary widely according to mode of transport, socioeconomic deprivation, and rurality. Policies changing the geographical configuration of cancer services should consider the impact on the expected travel times both by car and by public transport to avoid enhancing existing inequalities in access to treatment and patient outcomes.

County-level colorectal cancer screening rates on colorectal cancer survival in the state of Georgia: Does county-level rurality matter?

PURPOSE

Investigating CRC screening rates and rurality at the county-level may explain disparities in CRC survival in Georgia. Although a few studies examined the relationship of CRC screening rates, rurality, and/or CRC outcomes, they either used an ecological study design or focused on the larger population.

METHODS

We conducted a retrospective analysis utilizing data from the 2004-2010 Surveillance, Epidemiology, and End Results Program. The 2013 United States Department of Agriculture rural-urban continuum codes and 2004-2010 National Cancer Institute small-area estimates for screening behaviors were used to identify county-level rurality and CRC screening rates. Kaplan-Meier method and Cox proportional hazard regression were performed.

RESULTS

Among 22,160 CRC patients, 5-year CRC survival rates were lower among CRC patients living in low screening areas in comparison with intermediate/high areas (69.1% vs. 71.6% /71.3%; p-value = 0.030). Patients living in rural high-screening areas also had lower survival rates compared to non-rural areas (68.2% vs. 71.8%; p-value = 0.009). Our multivariable analysis demonstrated that patients living in intermediate (HR, 0.91; 95% CI, 0.85-0.98) and high-screening (HR, 0.92; 95% CI, 0.85-0.99) areas were at 8%-9% reduced risk of CRC death. Further, non-rural CRC patients living in intermediate and high CRC screening areas were 9% (HR, 0.91; 95% CI, 0.83-0.99) and 10% (HR, 0.90; 95% CI, 0.82-0.99) less likely to die from CRC.

CONCLUSIONS

Lower 5-year survival rates were observed in low screening and rural high-screening areas. Living in intermediate/high CRC screening areas was negatively associated with the risk of CRC death. Particularly, non-rural patients living in intermediate/high-screening areas were 8%-9% less likely to die from CRC. Targeted CRC screening resources should be prioritized for low screening and rural communities.

Barriers, facilitators, and priority needs related to cancer prevention, control, and research in rural, persistent poverty areas

PURPOSE

The purpose of this study was to identify the barriers, facilitators, and priority needs related to cancer prevention, control, and research in persistent poverty areas.

METHODS

We conducted three focus groups with 17 providers and staff of primary care clinics serving persistent poverty areas throughout the state of Arkansas.

RESULTS

We identified multiple barriers, facilitators, and priority needs related to cancer prevention and control at primary care clinics serving persistent poverty areas. Barriers included transportation, medical costs, limited providers and service availability, and patient fear/discomfort with cancer topics. Facilitators identified were cancer navigators and community health events/services, and priority needs included patient education, comprehensive workflows, improved communication, and integration of cancer navigators into healthcare teams. Barriers to cancer-related research were lack of provider/staff time, patient uncertainty/skepticism, patient health literacy, and provider skepticism/concerns regarding patient burden. Research facilitators included better informing providers/staff about research studies and leveraging navigators as a bridge between clinic and patients.

CONCLUSION

Our results inform opportunities to adapt and implement evidence-based interventions to improve cancer prevention, control, and research in persistent poverty areas. To improve cancer prevention and control, we recommend locally-informed strategies to mitigate patient barriers, improved patient education efforts, standardized patient navigation workflows, improved integration of cancer navigators into care teams, and leveraging community health events. Dedicated staff time for research, coordination of research and clinical activities, and educating providers/staff about research studies could improve cancer-related research activities in persistent poverty areas.

Colorectal Cancer Knowledge and Screening Change in African Americans: Implementation Phase Results of the EPICS Cluster RCT

Introduction

African Americans are disproportionately affected by mortality risk for colorectal cancer. This study aimed to determine the most effective educational approach of 4 study arms that enhances the likelihood of pursuing subsequent colorectal cancer screening, and to identify the associated factors.

Methods

Age-eligible adults (N=2,877) were recruited to participate in a cluster randomized control dissemination and intervention implementation trial titled Educational Program to Increase Colorectal Cancer Screening. The project began in May 2012 and ended in March 2017 (the implementation phase lasted 36 months). Educational sessions were conducted through 16 community coalitions that were randomized into 1 of 4 conditions: website access (to facilitator training materials and toolkits) without technical assistance, website access with technical assistance, in-person training (provided by research staff and website access) without technical assistance, and in-person training with technical assistance. A follow-up to determine participant CRC screening was conducted 3 months later.

Results

Compared with the website access with technical assistance intervention group, 2 groups, in-person training with technical assistance and without technical assistance, indicated significantly higher odds for obtaining colorectal cancer screening (OR=1.31; 95% CI=1.04, 1.64; p=0.02 and OR=1.35; 95% CI=1.07, 1.71; p=0.01, respectively). Though sociodemographic factors were not significantly associated with pursuing subsequent colorectal cancer screening, the postintervention cancer knowledge increased significantly among the study participants.

Conclusions

The importance of in-person interactions, local coalitions, and community contexts may play a key role for successfully increasing colorectal cancer screening rates among African Americans as reflected through this study. The integration of telehealth and use of other virtual technologies to engage the public in research have increased since the COVID-19 pandemic and should be assessed to determine their impact on the degree to which in-person interventions are significantly more effective when compared with solely web-assisted ones.

Epidemiological Situation of High-Prevalence Non-Communicable Diseases in Spain: A Systematic Review

High-prevalence non-communicable diseases (HNCDs) are an ongoing global public health problem, posing a risk to the continuity of the 2030 Agenda for Sustainable Development. The aim of this study is to describe the current situation in Spain regarding certain HNCDs, namely, ischaemic heart disease, type 2 diabetes mellitus and colorectal cancer, including their prevalence and incidence in recent years. A systematic review was conducted between October 2022 and February 2023 using the MEDLINE, ProQuest and Scopus databases. After an exhaustive search, a total of thirty-four articles were included, comprising fourteen articles on colorectal cancer, seven on ischaemic heart disease and thirteen on diabetes mellitus type 2. The main topics included risk factors, lifestyles, mortality and incidence, the importance of screening and patient empowerment. On analysing each disease, it can be gleaned that risk factors and lifestyle impact the incidence, prevalence and mortality of the diseases studied. In addition, responsible human behaviour, associated with lifestyle factors, is related to the occurrence of these three diseases.

Social Determinants of Health in Imaging-based Cancer Screening: A Case-based Primer with Strategies for Care Improvement

Health disparities, preventable differences in the burden of disease and disease outcomes often experienced by socially disadvantaged populations, can be found in nearly all areas of radiology, including emergency radiology, neuroradiology, nuclear medicine, image-guided interventions, and imaging-based cancer screening. Disparities in imaging-based cancer screening are especially noteworthy given the far-reaching population health impact. The social determinants of health (SDoH) play an important role in disparities in cancer screening and outcomes. Through improved understanding of how SDoH can drive differences in health outcomes in radiology, radiologists can effectively provide patient-centered, high-quality, and equitable care. Radiologists and radiology practices can become active partners in efforts to assist patients along their imaging journey and overcome existing barriers to equitable cancer screening care for traditionally marginalized populations. As radiology exists at the intersection of diagnostic imaging, image-guided diagnostic intervention, and image-guided treatment, radiologists are uniquely positioned to design these strategies. Cost-effective and socially conscious strategies that address barriers to equitable care can improve both public health and equitable health outcomes. Potential strategies include championing supportive health policy, reducing out-of-pocket costs, increasing price transparency, improving education and outreach efforts, ensuring that appropriate language translation services are available, providing individualized assistance with appointment scheduling, and offering transportation assistance and childcare. ©RSNA, 2023 Quiz questions for this article are available in the supplemental material.

Exploring Caregiver Interest in and Preferences for Interventions for Children With Risk of Asthma Exacerbation: Web-Based Survey

BACKGROUND

Maintaining control of asthma symptoms is the cornerstone of asthma treatment guidelines in the United States. However, suboptimal asthma control and asthma exacerbations among young people are common and are associated with many negative outcomes. Interventions to improve asthma control are needed. For such interventions to be successful, it is necessary to understand the types of interventions that are appealing to caregivers of children with different levels of risk of exacerbation.

OBJECTIVE

This study aimed to evaluate whether caregivers of children with high (vs low) risk of asthma exacerbation show different levels of interest in and preferences for potential intervention programs and delivery methods.

METHODS

We contracted with Ipsos to administer a web-based survey to caregivers of children with asthma who were residing in the United States. Caregivers (N=394) reported their interest (1=not at all; 3=a lot) in 9 possible intervention programs and 8 possible intervention delivery methods. Caregivers also indicated their preferences by selecting the 3 intervention programs and 3 delivery methods that "most" interested them. Finally, caregivers completed 2 open-ended questions asking what other resources might be useful for managing their children's asthma. We classified children as having a high risk of exacerbation if they had an exacerbation in the past 3 months (n=116) and a low risk of exacerbation if otherwise (n=278).

RESULTS

Caregivers reported higher levels of interest in all intervention programs and delivery methods if they cared for a child with a high risk rather than a low risk of exacerbation. However, regardless of the child's risk status, caregivers expressed the highest levels of interest in programs to increase their child's self-management skills, to help pay for asthma care, and to work with the school to manage asthma. Caregivers expressed the highest levels of interest in delivery methods that maintained personal control over accessing information (websites, videos, printed materials, and smartphone apps). Caregivers' preferences were consistent with their interests; programs and delivery methods that were rated as high in interest were also selected as one of the 3 that "most" interested them. Although most caregivers did not provide additional suggestions for the open-ended questions, a few caregivers suggested intervention programs and delivery methods that we had not included (eg, education about avoiding triggers and medication reminders).

CONCLUSIONS

Similar interests and preferences among caregivers of children with high and low risk of exacerbation suggest a broad need for support in managing childhood asthma. Providers could help caregivers by directing them toward resources that make asthma care more affordable and by helping their children with asthma self-management. Interventions that accommodate caregivers' concerns about having personal control over access to asthma information are likely to be more successful than interventions that do not.
