Rural-Urban Disparities in Cancer Outcomes: Opportunities for Future Research

Exploring 6 years of colorectal cancer surgery in rural Italy: insights from 648 consecutive patients unveiling successes and challenges

The multidisciplinary management of patients suffering from colorectal cancer (CRC) has significantly increased survival over the decades and surgery remains the only potentially curative option for it. However, despite the implementation of minimally invasive surgery and ERAS pathway, the overall morbidity and mortality remain quite high, especially in rural populations because of urban - rural disparities. The aim of the study is to analyze the characteristics and the surgical outcomes of a series of unselected CRC patients residing in two similar rural areas in Italy. A total of 648 consecutive patients of a median age of 73 years (IQR 64-81) was enrolled between 2017 and 2022 in a prospective database. Emergency admission (EA) was recorded in 221 patients (34.1%), and emergency surgery (ES) was required in 11.4% of the patients. Tumor resection and laparoscopic resection rates were 95.0% and 63.2%, respectively. The median length of stay was 8 days. The overall morbidity and mortality rates were 23.5% and 3.2%, respectively. EA was associated with increased median age (77.5 vs. 71 ys, p < 0.001), increased mean ASA Score (2.84 vs. 2.59; p = 0.002) and increased IV stage disease rate (25.3% vs. 11.5%, p < 0.001). EA was also associated with lower tumor resection rate (87.3% vs. 99.1%, p < 0.001), restorative resection rate (71.5 vs. 89.7%, p < 0.001), and laparoscopic resection rate (36.2 vs. 72.6%, p < 0.001). Increased mortality rates were associated with EA (7.2% vs. 1.2%, p < 0.001), ES (11.1% vs. 2.0%, p < 0.001) and age more than 80 years (5.8% vs. 1.9%, p < 0.001). In rural areas, high quality oncologic care can be delivered in CRC patients. However, the surgical outcomes are adversely affected by a still too high proportion of emergency presentation of elderly and frail patients that need additional intensive care supports beyond the surgical skill and alternative strategies for earlier detection of the disease.

Primary Care Provider Visits Among Cancer Survivors 5-7 Years Postdiagnosis

PURPOSE

Cancer survivors experience better outcomes when primary care providers (PCPs) are engaged in their care. Nearly all survivors have a PCP engaged in their care in the initial 5 years postdiagnosis, but little is known about sustained PCP engagement. We assessed PCP engagement in survivors' care 5-7 years postdiagnosis and characterized survivors most vulnerable to loss to PCP follow-up.

METHODS

We linked electronic health record ambulatory care and cancer registry data from an National Cancer Institute-Designated Comprehensive Cancer Center to identify eligible survivors (≥18 years; diagnosed with breast, colorectal, or uterine cancer; had an in-network PCP). We used multiple logistic regression to assess associations between survivor demographics, clinical factors, and health care utilization and odds of sustained PCP engagement.

RESULTS

In 5-7 years postdiagnosis, PCPs were engaged in care for 43% of survivors. Survivors with sustained PCP-engagement were on average 4.6 years older than those without (P < .0001); survivors had 1.36 greater odds of having regular PCP visits for each decade increase in age on cancer diagnosis (P = .0030). Survivors were less likely to be lost to PCP follow-up if diagnosed at an earlier stage with odds at 0.57 and 0.10 for stage I and stage IV, respectively (P = .0005), and had 2.70 greater odds of engagement in care with at least one oncology visit annually 5-7 years postdiagnosis (P < .0001).

CONCLUSION

Sustained PCP engagement is endorsed as critical by survivors, PCPs, and oncologists. We found most survivors were lost to PCP follow-up 5-7 years postdiagnosis. Our study is among the first to contribute empirical evidence of survivors being lost in transition. Findings from this study demonstrate the need to bridge gaps in long-term care for cancer survivors.

Equity in oncology care: addressing disparities in cancer treatment in Georgia

This research delves into the disparities in access to oncology care among cancer patients in Georgia, with a specific focus on the distinct challenges faced by African American (AA) individuals compared to non-African American (Non-AA) counterparts. Leveraging data from the 2020 Behavioral Risk Factor Surveillance System (BRFSS) survey and supplementary online resources, the study meticulously examines socioeconomic factors, including income, education, and insurance coverage, which significantly influence the quality of cancer care received. The analysis reveals substantial income gaps between AA and Non-AA patients, underscoring the critical implications for healthcare access. Moreover, AA patients exhibit lower rates of full insurance coverage for cancer-related treatments, posing additional barriers to comprehensive care. By investigating the intersections of race, income, and education, the research aims to pinpoint the root causes of these disparities and proposes evidence-based solutions to address the identified challenges. The ultimate objective is to contribute valuable insights that inform targeted policy recommendations and community-based interventions, fostering a more equitable landscape for oncology care in Georgia. This study seeks to amplify awareness and advocate for tangible measures, striving toward healthcare equity for all cancer patients, irrespective of their racial or socioeconomic backgrounds.

Impact of the Affordable Care Act on access to accredited facilities for cancer treatment

OBJECTIVE

To examine differential changes in receipt of surgery at National Cancer Institute (NCI)-designated comprehensive cancer centers (NCI-CCC) and Commission on Cancer (CoC) accredited hospitals for patients with cancer more likely to be newly eligible for coverage under Affordable Care Act (ACA) insurance expansions, relative to those less likely to have been impacted by the ACA.

DATA SOURCES AND STUDY SETTING

Pennsylvania Cancer Registry (PCR) for 2010-2019 linked with discharge records from the Pennsylvania Health Care Cost Containment Council (PHC4).

STUDY DESIGN

Outcomes include whether cancer surgery was performed at an NCI-CCC or a CoC-accredited hospital. We conducted a difference-in-differences analysis, estimating linear probability models for each outcome that control for residence in a county with above median county-level pre-ACA uninsurance and the interaction between county-level baseline uninsurance and cancer treatment post-ACA to capture differential changes in access between those more and less likely to become newly eligible for insurance coverage (based on area-level proxy). All models control for age, sex, race and ethnicity, cancer site and stage, census-tract level urban/rural residence, Area Deprivation Index, and year- and county-fixed effects.

DATA COLLECTION/EXTRACTION METHODS

We identified adults aged 26-64 in PCR with prostate, lung, or colorectal cancer who received cancer-directed surgery and had a corresponding surgery discharge record in PHC4.

PRINCIPAL FINDINGS

We observe a differential increase in receiving care at an NCI-CCC of 6.2 percentage points (95% CI: 2.6-9.8; baseline mean = 9.8%) among patients in high baseline uninsurance areas (p = 0.001). Our estimate of the differential change in care at the larger set of CoC hospitals is positive (3.9 percentage points [95% CI: -0.5-8.2; baseline mean = 73.7%]) but not statistically significant (p = 0.079).

CONCLUSIONS

Our findings suggest that insurance expansions under the ACA were associated with increased access to NCI-CCCs.

A call to action to advance patient-focused and decentralized clinical trials

This commentary is a call to action for a concerted commitment and effort to transform clinical trials and enable people with cancer to participate in clinical trials closer to home. Three key strategies are identified to address major barriers: confront challenges with the interpretation of US Food and Drug Administration Form 1572 requirements (Statement of Investigator); broaden acceptance of local laboratories and imaging centers; and invest in the creation of effective, sustainable partnerships between research centers and local providers.

Survival after docetaxel for metastatic castration-resistant prostate cancer in a rural health care setting

Introduction

The aim of this study was to evaluate overall survival of men who received systemic therapy with docetaxel for metastatic castration- resistant prostate cancer (MCRPC) in rural Nordland County, Norway. Prognostic factors related to treatment and other variables were evaluated.

Material and methods

Overall, 132 pa- tients were included in this retrospective study covering the years 2009-2022. Uni- and multivariate survival analyses were performed.

Results

In this elderly cohort (median age 72 years), weekly low-dose docetaxel was the preferred regimen (44%). Seventy-three percent were treated in the first line. Only 11 patients (8%) were pre-exposed to docetaxel in the hormone-sensitive phase. Median survival was 14.3 months. Prognostic factors for longer survival included higher hemoglobin, lower lactate dehydrogenase, administration of docetaxel as first-line MCRPC treatment, and use of fewer prescription drugs for comorbidity. Pre-exposure to docetaxel did not play a major role, p = 0.76.

Conclusions

In this rural health care setting, survival after docetaxel was shorter than reported by other groups. Blood test results were confirmed as important prognostic factors. In the present era of evolving treatment sequences, we recommend monitoring of real-world treatment results.

Area-based disparities in non-small-cell lung cancer survival

BACKGROUND

In the Nordic countries, universal healthcare access has been effective in reducing socioeconomic disparities in non-small-cell lung cancer (NSCLC) management. However, other factors, such as proximity to healthcare facilities, may still affect access to care. This study aimed at investigating the influence of residential area on NSCLC survival.

METHODS

This population-based study utilized hospital records to identify NSCLC patients who underwent their initial treatment at Vaasa Central Hospital between January 1, 2016, and December 31, 2020. Patients were categorized based on their postal codes into urban areas (≤50 km from the hospital) and rural areas (>50 km from the hospital). Survival rates between these two groups were compared using Cox regression analysis.

RESULTS

A total of 321 patients were included in the study. Patients residing in rural areas (n = 104) exhibited poorer 12-month survival rates compared to their urban counterparts (n = 217) (unadjusted Hazard Ratio [HR]: 1.38; 95% Confidence Interval [CI]: 1.01-1.89; p = 0.042). After adjusting for factors such as performance status, frailty, and stage at diagnosis in a multivariate Cox regression model, the adjusted HR increased to 1.47 (95% CI: 1.07-2.01; p = 0.017) for patients living in rural areas compared to those in urban areas.

INTERPRETATION

The study findings indicate that the distance to the hospital is associated with increased lung cancer mortality. This suggests that geographical proximity may play a crucial role in the disparities observed in NSCLC survival rates. Addressing these disparities should involve strategies aimed at improving healthcare accessibility, particularly for patients residing in rural areas, to enhance NSCLC outcomes and reduce mortality.

Estimating the Impact of Rurality in Disparities in Cancer Mortality

PURPOSE

Estimation of the independent effect of rurality on cancer mortality requires causal inference methodology and consideration of area-level socioeconomic status and rural designations.

METHODS

Using SEER data, we identified key incident cancers diagnosed between 2000 and 2016 at age ≥20 years (N = 3,788,273), examining a 20% random sample (n = 757,655). Standardized competing risk and survival models estimated the association between rural residence, defined by Rural-Urban Continuum Codes, and cancer-specific and all-cause mortality, controlling for age at cancer diagnosis, sex, race/ethnicity, year of diagnosis, and Area Deprivation Index (ADI). We estimated the attributable fraction (AF) of rurality and high ADI (ADI > median) to the probability of mortality. Finally, we examined county measurement issues contributing to mortality rates discordant from hypothesized rates.

RESULTS

The 5-year standardized failure probability for cancer mortality for rural patients was 33.9% versus 31.56% for urban. The AF for rural residence was 1.04% at year 1 (0.89% by year 5), the highest among local stage disease (Y1 2.1% to Y5 1.9%). The AF for high ADI was 3.33% in Y1 (2.87% in Y5), while the joint effect of rural residence and high ADI was 4.28% in Y1 (3.71% in Y5). Twenty-two percent of urban counties and 30% of rural were discordant. Among discordant urban counties, 30% were only considered urban because of adjacency to metro area. High ADI was associated with urban discordance and low ADI with rural discordance.

CONCLUSION

Rural residence independently contributes to cancer mortality. The rural impact is the greatest among those with localized disease and in high deprivation areas. Rural-urban county designations may mask high-need urban counties, limiting eligibility to state and federal resources dedicated to rural areas.

Oncology Nurse Navigation in Underserved Communities: Opportunities and Future Directions

OBJECTIVES

Provide an overview of navigation in three disparate populations: rural, Native American/Alaska Native, and low- to middle-income countries. Discuss gaps in care and opportunities to improve cancer care.

METHODS

A literature search was conducted in PubMed and on Google Scholar using search terms, nurse navigation, cancer, disparit*, low- to middle-income countries, Native American, American Indian, and rural. Peer-reviewed research studies, review articles, databases and websites of professional organizations, and historical books were reviewed to provide an overview of oncology nurse navigation in underserved communities. Experiences in working with these populations over the past 30 years were also provided to support current literature.

RESULTS

Forty references were included in this overview of nurse navigation in underserved communities. Nurse navigation in these disparate areas is in its infancy. While some programs exist and outcomes have been positive, their dissemination is sparse. A need exists to expand nurse navigation into these areas to provide care for these underserved communities.

CONCLUSION

Oncology nursing navigation for each of these underserved communities requires a culturally sensitive approach. Many of these approaches are universal to cultural competency and can be applied to most disparate populations.

IMPLICATIONS FOR NURSING PRACTICE

Nurses comprise the largest workforce around the globe and are well-equipped to develop navigation programs in some of the most disparate communities around the world. To do so, it is important to use a foundation of building trust, embracing individual differences, providing culturally sensitive education and resources for growth, and good communication.

What is the relationship between the local population change and cancer incidence in patients with dyslipidemia: Evidence of the impact of local extinction in Korea

BACKGROUND

Changes in the local population are intricately linked to healthcare infrastructure, which subsequently impacts the healthcare sector. A decreasing local population can result in lagging health infrastructure, potentially leading to adverse health outcomes as patients may be at risk of not receiving optimal care and treatment. While some studies have explored the relationship between chronic diseases and local population decline, evidence regarding cancer is insufficient. In this study, we focused on how deteriorating management of chronic diseases such as dyslipidemia could influence the risk of cancer. We investigated the relationship between changes in the local population and cancer incidence among patients with dyslipidemia.

METHODS

This cohort study was conducted using claims data. Data from adult patients with dyslipidemia from the National Health Insurance Service-National Sample Cohort conducted between 2002 and 2015 were included. Population changes in each region were obtained from the Korean Statistical Information Service and were used to link each individual's regional code. Cancer risk was the dependent variable, and Cox proportional hazards regression was used to estimate the target associations.

RESULTS

Data from 336,883 patients with dyslipidemia were analyzed. Individuals who resided in areas with a decreasing population had a higher risk of cancer than those living in areas with an increasing population (decrease: hazard ratio (HR) = 1.06, 95% CI = 1.03-1.10; normal: HR = 1.05, 95% CI = 1.02-1.09). Participants living in regions with a low number of hospitals had a higher risk of cancer than those in regions with a higher number of hospitals (HR = 1.20, 95% CI = 1.12-1.29).

CONCLUSION

Patients in regions where the population has declined are at a higher risk of cancer, highlighting the importance of managing medical problems caused by regional extinction. This could provide evidence for and useful insights into official policies on population decline and cancer risk.

Factors contributing to differences in cervical cancer screening in rural and urban community health centers

INTRODUCTION

Community health centers (CHCs) provide historically marginalized populations with primary care, including cancer screening. Previous studies have reported that women living in rural areas are less likely to be up to date with cervical cancer screening than women living in urban areas. However, little is known about rural-urban differences in cervical cancer screening in CHCs and the contributing factors, and whether such differences changed during the COVID-19 pandemic.

METHODS

Using 8-year pooled Uniform Data System (2014-2021) data and Oaxaca-Blinder decomposition, the extent to which CHC- and catchment area-level characteristics explained rural-urban differences in up-to-date cervical cancer screening was estimated.

RESULTS

Up-to-date cervical cancer screening was lower in rural CHCs than urban CHCs (38.2% vs 43.0% during 2014-2019), and this difference increased during the pandemic (43.5% vs 49.0%). The rural-urban difference in cervical cancer screening in 2014-2019 was mostly explained by differences in CHC-level proportions of patients with limited English proficiency (55.9%) or income below the poverty level (12.3%) and females aged 21 to 64 years (9.8%), and catchment area-level's unemployment (3.4%) and primary care physician density (3.2%). However, Medicaid (-48.5%) or no insurance (-19.6%) counterbalanced the differences between rural-urban CHCs. The contribution of these factors to rural-urban differences in cervical cancer screening generally increased in 2020-2021.

CONCLUSIONS

Rural-urban differences in cervical cancer screening were mostly explained by multiple CHC-level and catchment area-level characteristics. The findings call for tailored interventions, such as providing resources and language services, to improve cancer screening utilization among uninsured, Medicaid, and patients with limited English proficiency in rural CHCs.

Rural-urban disparity in cancer burden and care: findings from an Indian cancer registry

BACKGROUND

Cancer incidence and mortality vary across the globe, with nearly two-thirds of cancer-related deaths occurring in low- and middle-income countries. The rural-urban disparity in socio-demographic, behavioural, and lifestyle-related factors, as well as in access to cancer care, is one of the contributing factors. Population-based cancer registries serve as a measure for understanding the burden of cancer. We aimed to evaluate the rural-urban disparity in cancer burden and care of patients registered by an Indian population-based cancer registry.

METHODS

This study collected data from Varanasi, Uttar Pradesh, India, between 2017 and 2019. Sex and site-specific age-standardised rates for incidence and mortality per 100,000 population were calculated. Rural-urban disparities in cancer incidence and mortality were estimated through rate differences and standardised rate ratios (with 95% confidence intervals). Univariable and multivariable regressions were applied to determine any significant differences in socio-demographic and cancer-related variables according to place of residence (rural/urban). Crude and adjusted odds ratios with 95% confidence intervals were calculated.

RESULTS

6721 cancer patients were registered during the study duration. Urban patients were older and had better literacy and socioeconomic levels, while rural patients had higher odds of having unskilled or semi-skilled professions. Diagnostic and clinical confirmation for cancer was significantly higher in urban patients, while verbal autopsy-based confirmation was higher in rural patients. Rural patients were more likely to receive palliative or alternative systems of medicine, and urban patients had higher chances of treatment completion. Significantly higher incidence and mortality were observed for oral cancer among urban men and for cervical cancer among rural women. Despite the higher incidence of breast cancer in urban women, significantly higher mortality was observed in rural women.

CONCLUSIONS

Low- and middle-income countries are facing dual challenges for cancer control and prevention. Their urban populations experience unhealthy lifestyles, while their rural populations lack healthcare accessibility. The distinctness in cancer burden and pattern calls for a re-evaluation of cancer control strategies that are tailor-made with an understanding of urban-rural disparities. Context-specific interventional programmes targeting risk-factor modifications, cancer awareness, early detection, and accessibility to diagnosis and care are essential.

Cervical Cancer: Preventable Deaths Among American Indian/Alaska Native Communities

American Indian/Alaska Native (AI/AN) individuals have twice the mortality rate of cervical cancer than the general US population. Participation in prevention programs such as cervical cancer screening and human papillomavirus (HPV) vaccination are under-utilized in this population. There are high rates of established cervical cancer risk factors among this community, with AI/AN people having a higher likelihood of infection with high-risk HPV strains not included in the 9-valent vaccine. There is a need for more robust and urgent prevention and treatment efforts in regard to cervical cancer in the AI/AN community.

Contribution of County Characteristics to Disparities in Rural Mortality After Cancer Diagnosis

INTRODUCTION

Rural disparities in cancer outcomes have been widely evaluated, but limited evidence is available to describe what characteristics of rural environments contribute to the increased risk of poor outcomes. Therefore, this manuscript sought to assess the mediating effects of county characteristics on the relationship between urban/rural status and mortality among patients with cancer, characterize county profiles, and determine at-risk county profiles alongside rural settings.

METHODS

Patients diagnosed with cancer between 2000 and 2016 were assessed using Surveillance, Epidemiology and End Results data linked to the 2010 Rural-Urban Commuting Codes and 2010 County Health Rankings. There were 757,655 patients representing 596 counties (of 3,143 in the U.S.) and 12 states. Mediation analyses, conducted in 2023, estimated the direct contribution of rurality to 5-year all-cause survival and the contribution of the rural effect indirectly through County Health Ranking domains. Latent class analysis and survival models identified county groupings and estimated the hazard of mortality associated with class membership.

RESULTS

Rankings for premature death, clinical care, and physical environment resulted in rural patients having 17.9%-20.2% less survival time than urban patients. Of this, 4.1%-12.6% of the total excess risk was mediated by these characteristics. Patients living in rural and high-risk county classes saw higher all-cause mortality than those in urban lower-risk counties (hazard ratio=1.04, 95% CI=1.01, 1.08 and 1.07, 95% CI=1.03, 1.11).

CONCLUSIONS

Counties with poorer health rankings had increased mortality risks regardless of rurality; however, the poor rankings, notably health behaviors and social and economic factors, elevated the risk for rural counties.

A systematic review on the qualitative experiences of people living with lung cancer in rural areas

PURPOSE

To synthesize the qualitative literature exploring the experiences of people living with lung cancer in rural areas.

METHODS

Searches were performed in MEDLINE, CINAHL, and PsycINFO. Articles were screened independently by two reviewers against pre-determined eligibility criteria. Data were synthesized using Thomas and Harden's framework for the thematic synthesis of qualitative research. The CASP qualitative checklist was used for quality assessment and the review was reported in accordance with the ENTREQ and PRISMA checklists.

RESULTS

Nine articles were included, from which five themes were identified: (1) diagnosis and treatment pathways, (2) travel and financial burden, (3) communication and information, (4) experiences of interacting with healthcare professionals, (5) symptoms and health-seeking behaviors. Lung cancer diagnosis was unexpected for some with several reporting treatment delays and long wait times regarding diagnosis and treatment. Accessing treatment was perceived as challenging and time-consuming due to distance and financial stress. Inadequate communication of information from healthcare professionals was a common concern expressed by rural people living with lung cancer who also conveyed dissatisfaction with their healthcare professionals. Some were reluctant to seek help due to geographical distance and sociocultural factors whilst others found it challenging to identify symptoms due to comorbidities.

CONCLUSIONS

This review provides a deeper understanding of the challenges faced by people with lung cancer in rural settings, through which future researchers can begin to develop tailored support to address the existing disparities that affect this population.

ChatGPT: Is This Patient Education Tool for Urological Malignancies Readable for the General Population?

Background

With widespread adoption of technological advancements in everyday life, patients are now increasingly able and willing to obtain information about their health conditions, treatment options, and indeed expected outcomes via the convenience of any device than can access the worldwide web. This introduces another aspect of patient care in the provision of healthcare for the modern doctor. ChatGPT is the first of an increasing number of self learning programs that have been released recently which may revolutionize and impact healthcare delivery.

Methods

The aim of this study is to obtain an objective measure of the readability of information provided on ChatGPT when compared with current validated patient information sheets provided by government health institutions in Western Australia. The same structured questions were input into the program for three major urological malignancies (urothelial, renal, and prostate), with the response generated evaluated with a validated readability scoring system - Flesch-Kincaid reading ease score. The same scoring system was then applied to current patient information sheets in circulation from Cancer Council Australia and UpToDate.

Results

Findings in this study looking at ease of readability of information provided on ChatGPT as compared to other government bodies and healthcare institutions confirm that they are non-inferior and may be a useful tool or adjunct to the traditional clinic based consultations. Ease of use of the information generated from ChatGPT was increased further when the question was modified to target an audience of 16 years of age, the average level of education attained by an Australian.

Discussion

Future research can be done to look into incorporating the use of similar technologies to increase efficiency in the healthcare system and reduce healthcare costs.

Race/ethnicity and sex differences in the association between area-level arsenic exposure concentration and hepatocellular carcinoma (HCC) incidence rates in Texas. An ecological study

INTRODUCTION

Texas has the highest rates of hepatocellular carcinoma (HCC) in the United States. Exposure to toxicants may play a role in liver disease. Several mechanisms of arsenic carcinogenesis have been proposed, however, the evidence in human populations is limited to associations between HCC and ingestion of arsenic-contaminated drinking water. Through an ecological study, we examined associations between ambient arsenic and HCC incidence rates.

METHODS

Primary outcome was HCC incidence rates based on Texas Cancer Registry (TCR) data. Primary exposure of interest was the simulated census-tract level estimate of arsenic exposure concentration (EC) from the U.S. Environmental Protection Agency 2011 National Air Toxics Assessment (NATA). We analyzed the association between the arsenic EC and HCC using the negative binomial Poisson regression model separately for six study groups that were based on race/ethnicity and sex. We adjusted the main analyses for selected characteristics.

RESULTS

Texas has 5265 census tracts and TCR reported 18,235 new ≥20 years old HCC diagnoses between 2007 and 2015. We observed significant differences along racial-ethnic and sex groups while accounting for socioeconomic deprivation, urban/rural residency, and senior residents' health insurance status. Census tracts with the highest arsenic EC had elevated rates of HCC among NH black men (Quintile 5 vs. Quintile 1: IRR = 2.18, 95% CI: 1.66-2.86), NH black women (Quintile 5 vs. Quintile 1: IRR = 1.72, 95% CI: 1.33-2.22) and NH white men (Quintile 5 vs. Quintile 1: IRR = 1.38, 95% CI: 1.24-1.54). The associations in the remaining study groups were either inconsistent or attenuated.

CONCLUSIONS

Our finding suggests a potential inhalation pathway for the Arsenic-HCC association; however, the ecological nature of our study precludes the interpretation of a causal link between exposure to aerial arsenic and HCC. This finding needs to be further examined in cohort studies.

Veterans with blood cancers: Clinical trial navigation and the challenge of rurality

PURPOSE

The proportion of cancer patients who participate in clinical trials (CTs) remains low, despite an understanding of barriers to enrollment. The barrier of rural residence is relevant to Veterans, who more commonly live in rural areas than non-Veterans. In this exploratory study, we aimed to examine geographic factors that could impede CT enrollment and to improve access to CTs for Veterans.

METHODS

To assess the influence of rurality on the availability of CTs, we performed simulated searches using The Leukemia & Lymphoma Society's Clinical Trial Support Center (LLS CTSC) database. The LLS CTSC provides free CT education and navigation. In the second part of this study, we offered Veterans with blood cancers who received care at the Durham, Salem, Clarksburg, Sioux Falls, and Houston Veterans Administration (VA) Medical Centers referral to the LLS CTSC.

FINDINGS

In simulated searches, we found significantly lower numbers of CTs open to enrollment in rural areas, compared to urban areas. In actual referrals, 33 Veterans were referred to the LLS CTSC, of which 15 (45%) lived in rural areas. Three Veterans enrolled in CTs. Patients declined referral or did not enroll in CTs for various reasons, including a desire to maintain care within the VA and/or to initiate therapy quickly.

CONCLUSIONS

We identified "clinical trial deserts," which might hinder access and reduce CT participation for rural Veterans. Referral to the LLS CTSC promoted CT education and enrollment among a highly rural cohort of Veterans receiving care in the VA system.

Factors Associated with Delaying and Forgoing Care Due to Cost among Long-term, Appalachian Cancer Survivors in Rural North Carolina

Background

Little research exists on delayed and forgone health and mental health care due to cost among rural cancer survivors.

Methods

We surveyed survivors in 7 primarily rural, Appalachian counties February to May 2020. Univariable analyses examined the distribution and prevalence of delayed/forgone care due to cost in the past year by independent variables. Chi-square or Fisher's tests examined bivariable differences. Logistic regressions assessed the odds of delayed/forgone care due to cost.

Results

Respondents (n=428), aged 68.6 years on average (SD: 12.0), were 96.3% non-Hispanic white and 49.8% female; 25.0% reported delayed/forgone care due to cost. The response rate was 18.5%. The proportion of delayed/forgone care for those aged 18-64 years was 46.7% and 15.0% for those aged 65+ years (P<0.0001). Females aged 65+ years (OR: 2.00; CI: 1.02-3.93) had double the odds of delayed/forgone care due to cost compared to males aged 65+ years.

Conclusion

About one in four rural cancer survivors reported delayed/forgone care due to cost, with rates approaching 50% in survivors aged <65 years.

Impact

Clinical implications indicate the need to: 1) ask about the impact of care costs, and 2) provide supportive services to mitigate effects of treatment costs, particularly for younger and female survivors.

Prioritizing rural populations in state comprehensive cancer control plans: a qualitative assessment

PURPOSE

The Centers for Disease Control and Prevention's National Comprehensive Cancer Control Program (NCCCP) requires that states develop comprehensive cancer control (CCC) plans and recommends that disparities related to rural residence are addressed in these plans. The objective of this study was to explore rural partner engagement and describe effective strategies for incorporating a rural focus in CCC plans.

METHODS

States were selected for inclusion using stratified sampling based on state rurality and region. State cancer control leaders were interviewed about facilitators and barriers to engaging rural partners and strategies for prioritizing rural populations. Content analysis was conducted to identify themes across states.

RESULTS

Interviews (n = 30) revealed themes in three domains related to rural inclusion in CCC plans. The first domain (barriers) included (1) designing CCC plans to be broad, (2) defining "rural populations," and (3) geographic distance. The second domain (successful strategies) included (1) collaborating with rural healthcare systems, (2) recruiting rural constituents, (3) leveraging rural community-academic partnerships, and (4) working jointly with Native nations. The third domain (strategies for future plan development) included (1) building relationships with rural communities, (2) engaging rural constituents in planning, (3) developing a better understanding of rural needs, and (4) considering resources for addressing rural disparities.

CONCLUSION

Significant relationship building with rural communities, resource provision, and successful strategies used by others may improve inclusion of rural needs in state comprehensive cancer control plans and ultimately help plan developers directly address rural cancer health disparities.

Area deprivation and rurality impact overall survival and adjuvant therapy administration in patients with pancreatic ductal adenocarcinoma (PDAC)

BACKGROUND

The impact of neighborhood deprivation on outcomes in patients with pancreatic ductal adenocarcinoma (PDAC) is not well-described and represents an area to improve disparities.

METHODS

We retrospectively queried our prospectively maintained database of patients with PDAC (2014-2022). Patients were grouped by Area Deprivation Index (ADI) and rural-urban commuting area (RUCA) codes. Cox proportional hazards models and logistic regressions were used to investigate effect on overall survival (OS) and adjuvant therapy administration.

RESULTS

536 patients were included. High ADI patients (more disadvantaged, n = 184) were more likely to identify as non-Hispanic Black (17.9% vs. 4.8%, p < 0.01) and were more likely to be from rural areas (49.5% vs. 18.5%, p < 0.01). High ADI was independently associated with decreased OS (HR (95% CI): 1.31 (1.01-1.69), p = 0.04). Urban high ADI patients were 3.5 times more likely to receive adjuvant therapy than rural high ADI patients (OR [95% CI]: 3.48 [1.26-9.61], p = 0.02).

CONCLUSION

Patients from the most disadvantaged neighborhoods have decreased OS. Access to adjuvant therapy likely contributes to this disparity in rural areas. Investigation into sources of this OS disparity and identification of barriers to adjuvant therapy will be crucial to improve outcomes in underserved patients with PDAC.

The impact of travel time to cancer treatment centre on post-diagnosis care and mortality among cancer patients in Scotland

Limited data exist on the effect of travelling time on post-diagnosis cancer care and mortality. We analysed the impact of travel time to cancer treatment centre on secondary care contact time and one-year mortality using a data-linkage study in Scotland with 17369 patients. Patients with longer travelling time and island-dwellers had increased incidence rate of secondary care cancer contact time. For outpatient oncology appointments, the incidence rate was decreased for island-dwellers. Longer travelling time was not associated with increased secondary care contact time for emergency cancer admissions or time to first emergency cancer admission. Living on an island increased mortality at one-year. Adjusting for cancer-specific secondary care contact time increased the hazard of death, and adjusting for oncology outpatient time decreased the hazard of death for island-dwellers. Those with longer travelling times experience the cancer treatment pathway differently with poorer outcomes. Cancer services may need to be better configured to suit differing needs of dispersed populations.

The Association of Rural Residence With Surgery and Adjuvant Radiation in Medicare Beneficiaries With Rectal Cancer

Purpose

Radiation therapy and surgery are fundamental site-directed therapies for nonmetastatic rectal cancer. To understand the relationship between rurality and access to specialized care, we characterized the association of rural patient residence with receipt of surgery and radiation therapy among Medicare beneficiaries with rectal cancer.

Methods and Materials

We identified fee-for-service Medicare beneficiaries aged 65 years or older diagnosed with nonmetastatic rectal cancer from 2016 to 2018. Beneficiary place of residence was assigned to one of 3 geographic categories (metropolitan, micropolitan, or small town/rural) based on census tract and corresponding rural urban commuting area codes. Multivariable regression models were used to determine associations between levels of rurality and receipt of both radiation and proctectomy within 180 days of diagnosis. In addition, we explored associations between patient rurality and characteristics of surgery and radiation such as minimally invasive surgery (MIS) or intensity modulated radiation therapy (IMRT).

Results

Among 13,454 Medicare beneficiaries with nonmetastatic rectal cancer, 3926 (29.2%) underwent proctectomy within 180 days of being diagnosed with rectal cancer, and 1792 (13.3%) received both radiation and proctectomy. Small town/rural residence was associated with an increased likelihood of receiving both radiation and proctectomy within 180 days of diagnosis (adjusted subhazard ratio, 1.15; 95% CI, 1.02-1.30). Furthermore, small town/rural radiation patients were significantly less likely to receive IMRT (adjusted odds ratio, 0.62; 95% CI, 0.48-0.80) or MIS (adjusted odds ratio, 0.80; 95% CI, 0.66-0.97) than metropolitan patients.

Conclusions

Although small town/rural Medicare beneficiaries were overall more likely to receive both radiation and proctectomy for their rectal cancer, they were less likely to receive preoperative IMRT or MIS as part of their treatment regimen. Together, these findings clarify that among Medicare beneficiaries, there appeared to be a similar utilization of radiation resources and time to radiation treatment regardless of rural/urban status.

Association of rurality, socioeconomic status, and race with pancreatic cancer surgical treatment and survival

BACKGROUND

Pancreatectomy is a necessary component of curative intent therapy for pancreatic cancer, and patients living in nonmetropolitan areas may face barriers to accessing timely surgical care. We evaluated the intersecting associations of rurality, socioeconomic status (SES), and race on treatment and outcomes of Medicare beneficiaries with pancreatic cancer.

METHODS

We conducted a retrospective cohort study, using fee-for-service Medicare claims of beneficiaries with incident pancreatic cancer (2016-2018). We categorized beneficiary place of residence as metropolitan, micropolitan, or rural. Measures of SES were Medicare-Medicaid dual eligibility and the Area Deprivation Index. Primary study outcomes were receipt of pancreatectomy and 1-year mortality. Exposure-outcome associations were assessed with competing risks and logistic regression.

RESULTS

We identified 45 915 beneficiaries with pancreatic cancer, including 78.4%, 10.9%, and 10.7% residing in metropolitan, micropolitan, and rural areas, respectively. In analyses adjusted for age, sex, comorbidity, and metastasis, residents of micropolitan and rural areas were less likely to undergo pancreatectomy (adjusted subdistribution hazard ratio = 0.88 for rural, 95% confidence interval [CI] = 0.81 to 0.95) and had higher 1-year mortality (adjusted odds ratio = 1.25 for rural, 95% CI = 1.17 to 1.33) compared with metropolitan residents. Adjustment for measures of SES attenuated the association of nonmetropolitan residence with mortality, and there was no statistically significant association of rurality with pancreatectomy after adjustment. Black beneficiaries had lower likelihood of pancreatectomy than White, non-Hispanic beneficiaries (subdistribution hazard ratio = 0.80, 95% CI = 0.72 to 0.89, adjusted for SES). One-year mortality in metropolitan areas was higher for Black beneficiaries (adjusted odds ratio = 1.15, 95% CI = 1.05 to 1.26).

CONCLUSIONS

Rurality, socioeconomic deprivation, and race have complex interrelationships and are associated with disparities in pancreatic cancer treatment and outcomes.

Socioeconomic Disparities Affect Outcomes in Early-Stage Esophageal Adenocarcinoma: A SEER Analysis

BACKGROUND & AIMS

Socioeconomic determinants of health are understudied in early stage esophageal adenocarcinoma. We aimed to assess how socioeconomic status influences initial treatment decisions and survival outcomes in patients with T1a esophageal adenocarcinoma.

METHODS

We performed an observational study using the 2018 submission of the Surveillance, Epidemiology, and End Results-18 database. A total of 1526 patients from 2004 to 2015 with a primary T1aN0M0 esophageal adenocarcinoma were subdivided into 3 socioeconomic tertiles based on their median household income. Endoscopic trends over time, rates of endoscopic and surgical treatment, 2- and 5-year overall survival, cancer-specific mortality, and non-cancer-specific mortality were calculated. Statistical analysis was performed using R-studio.

RESULTS

Patients within the lowest median household income tertile ($20,000-$54,390) were associated with higher cancer-specific mortality at 2 years (P < .01) and 5 years (P < .02), and lower overall survival at 2 and 5 years (P < .01) compared with patients in higher income tertiles. Patients with a higher income had a decreased hazard ratio for cancer-specific mortality (hazard ratio, 0.66; 95% CI, 0.45-0.99) in a multivariate Cox proportional hazards regression model. Patients within the higher income tertile were more likely to receive endoscopic intervention (P < .001), which was associated with improved cancer-specific mortality compared with patients who received primary surgical intervention (P = .001). The South had lower rates of endoscopy compared with other regions.

CONCLUSIONS

Lower median household income was associated with higher rates of cancer-specific mortality and lower rates of endoscopic resection in T1aN0M0 esophageal adenocarcinoma. Population-based strategies aimed at identifying and rectifying possible etiologies for these socioeconomic and geographic disparities are paramount to improving patient outcomes in early esophageal cancer.

Nationwide trends in and regional factors associated with minimally invasive hysterectomy for benign indications in Japan

OBJECTIVE

To examine the prevalence trends of minimally invasive hysterectomy for benign indications in Japan and investigate regional disparities.

STUDY DESIGN

A retrospective cohort and ecological study using "The National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB) Open Data".

SETTING

Nationwide Japan.

PATIENTS

Individuals who underwent hysterectomy for benign indications from 2014 to 2020.

INTERVENTIONS

Trend analysis of minimally invasive surgery (MIS) rates through laparoscopic hysterectomies (LH) and robotic-assisted laparoscopic hysterectomies (RA-LH) at the national and prefecture levels. Examination of regional factors contributing to the disparity in MIS implementation rates by second medical service area (SMSA).

RESULTS

The number of LH has increased from 16,016 in 2014 to 27,755 in 2020. The nationwide MIS hysterectomy rate increased from 29% in 2014 to 55% in 2020 (p less than 0.001). More than 50% of hysterectomies have been performed as MIS since 2019. There was an increasing trend in MIS rates in all age groups. All prefectures except one showed a significant upward trend (p less than 0.05) in the MIS rates, but MIS rates varied widely (23-84%). In a multivariable model, the MIS was more likely to be performed in the SMSAs in western Japan (p = 0.011), in the SMSAs where the number of laparoscopy-qualified gynecologists is 5-10 (p = 0.013), and 11 or higher (p less than 0.001).

CONCLUSIONS

This study reveals a shift towards minimally invasive surgery (MIS) in total hysterectomy procedures in Japan. However, significant disparities in the prevalence of MIS hysterectomy exist, potentially influenced by the number of laparoscopy-qualified gynecologists.

Health Equity and Antibiotic Prescribing in the United States: A Systematic Scoping Review

We performed a scoping review of articles published from 1 January 2000 to 4 January 2022 to characterize inequities in antibiotic prescribing and use across healthcare settings in the United States to inform antibiotic stewardship interventions and research. We included 34 observational studies, 21 cross-sectional survey studies, 4 intervention studies, and 2 systematic reviews. Most studies (55 of 61 [90%]) described the outpatient setting, 3 articles were from dentistry, 2 were from long-term care, and 1 was from acute care. Differences in antibiotic prescribing were found by patient's race and ethnicity, sex, age, socioeconomic factors, geography, clinician's age and specialty, and healthcare setting, with an emphasis on outpatient settings. Few studies assessed stewardship interventions. Clinicians, antibiotic stewardship experts, and health systems should be aware that prescribing behavior varies according to both clinician- and patient-level markers. Prescribing differences likely represent structural inequities; however, no studies reported underlying drivers of inequities in antibiotic prescribing.

Disparities in cancer mortality patterns: A comprehensive examination of U.S. rural and urban adults, 1999-2020

BACKGROUND

Cancer mortality rates overall in the U.S. have decreased significantly; however, the rate of decline has not been uniform across sociodemographic groups. We aimed to compare trends in cancer mortality rates from 1999 to 2020 between rural and urban individuals and to examine whether any rural-urban differences are uniform across racial and ethnic groups.

METHODS

We used U.S.-wide data from the National Center for Health Statistics, for all cancer deaths among individuals aged 25 years or older. We estimated average annual percentage change (AAPC) in age-standardized cancer mortality rates in the U.S. by cancer type, rural-urban status, sex, and race and ethnicity.

RESULTS

There was a larger reduction in cancer mortality rates among individuals from urban (males: AAPC, -1.96%; 95% CI, -2.03, -1.90; females: AAPC, -1.56%; 95% CI, -1.64, -1.48) than rural (males: AAPC, -1.43%; 95% CI, -1.47, -1.39; females: AAPC, -0.93; 95% CI, -1.03, -0.82) areas. AAPCs for cancer types were uniformly higher among urban areas compared with rural areas. Despite overall decreases, deaths rates for liver and pancreas cancers increased, including in the most recent period among males (2012-2020, APC, 1.34; 95% CI, 0.49, 2.20) and females (2013-2020, APC, 1.52; 95% CI, 0.03, 3.02) in rural areas.

CONCLUSIONS

Cancer death rates decreased in all racial and ethnic populations; however, the rural-urban differences varied by race/ethnicity. The rate of decline in mortality rates were lower in rural areas and death rates for liver and pancreas cancers increased, particularly for individuals living in rural America.

Survival of 48866 cancer patients: results from Nantong area, China

Objective

This study aimed to provide a realistic observation of survival by major site for 48,866 cancer patients treated at a tertiary cancer hospital in a rural area of China.

Methods

Patients with cancer registered between 2007 and 2017 in the Nantong rural area were followed up. The starting date for survival calculation was the date of the first diagnosis of cancer at the Nantong Tumor Hospital, and the closing date was December 31, 2020. Observed survival (OS) was analyzed according to ICD-10 site, sex, age, region, and hospitalization period using the life table method and compared using the Wilcoxon (Gehan) statistic.

Results

The overall 5-year OS rate was 40.48% for all 48,866 patients, 30.19% for males, and 51.90% for females. The top five cancer sites, accounting for 60.51% of the total cases, were the esophagus, lung, stomach, liver, and cervix, with 5-year OS rates of 33.72%, 18.64%, 32.10%, 19.04%, and 71.51%, respectively. The highest 5-year OS was observed in the thyroid (87.52%) and the lowest was in the pancreas (6.37%). Survival was significantly higher in younger patients than in older patients, with 5-year OSs of 69.26% and 19.84% in those aged 20-29 and 90-99 years, respectively. Five-year OSs improved significantly from 39.35% in 2007-2011 to 41.26% in 2012-2017.

Conclusion

Overall survival improved over the years, although the improvement at some sites was not significant. The observed survival varies from region to region, reflecting differences in the patterns of major sites, disparities in proportions of hospitalization, and demographic characteristics.

Addressing Cancer Disparities Through Community Engagement: Lessons and Best Practices

Cancer disparities continue to be a significant public health challenge, disproportionately affecting certain communities in terms of incidence, mortality, and access to quality care. Addressing these disparities requires a multifaceted approach that involves not only healthcare professionals and researchers but also the active participation and collaboration of the affected communities themselves. Community engagement has emerged as a promising strategy to reduce cancer disparities and promote health equity. This review article synthesizes the existing literature and examines the role of community engagement in addressing cancer disparities. It explores various approaches and best practices utilized in community engagement initiatives to empower and involve diverse populations in the fight against cancer. The review discusses key lessons learned from successful programs and identifies challenges faced in implementing such initiatives. The article highlights the importance of cultural competence, trust-building, and meaningful collaboration between stakeholders, including community leaders, healthcare providers, researchers, and policymakers. It emphasizes the significance of tailoring interventions to specific community needs, acknowledging cultural differences, and fostering a two-way exchange of knowledge and resources. Moreover, this review investigates the impact of community engagement on cancer prevention, early detection, treatment adherence, and survivorship outcomes. It sheds light on the role of community-based participatory research and other innovative strategies in generating evidence and facilitating the translation of research findings into real-world interventions. In conclusion, this review underlines the potential of community engagement in addressing cancer disparities and promoting health equity. By involving communities as active partners in cancer control efforts, healthcare systems can design more effective and sustainable interventions. This approach not only contributes to reducing cancer disparities but also fosters a sense of ownership and empowerment within the communities affected, paving the way for a more equitable and inclusive healthcare landscape.

Teleoncology: Novel Approaches for Improving Cancer Care in North America

Due to widespread healthcare workforce shortages, many patients living in remote and rural North America currently have reduced access to various medical specialists. These shortages, coupled with the aging North American population, highlight the need to transform contemporary healthcare delivery systems. The exchange of medical information via telecommunication technology, known as telemedicine, offers promising solutions to address the medical needs of an aging population and the increased demand for specialty medical services. This progressive movement has also improved access to quality health care by mitigating the current shortage of trained subspecialists. Minimizing the effects of these shortages is particularly urgent in the care of cancer patients, many of whom require regular follow-up and close monitoring. Cancer patients living in remote areas of North America have reduced access to specialized care and, thus, have unacceptably high mortality and morbidity rates. Teleoncology, or the use of telemedicine to provide oncology services remotely, has the ability to improve access to high-quality care and assist in alleviating the burden of some of the severe adverse events associated with cancer. In this review, the authors describe how recent advances in teleoncology can reduce healthcare disparities and improve future cancer care in North America.

Geographical and spatial variations in bowel cancer screening participation, Australia, 2015-2020

BACKGROUND

Participation in bowel cancer screening programs remains poor in many countries. Knowledge of geographical variation in participation rates may help design targeted interventions to improve uptake. This study describes small-area and broad geographical patterns in bowel screening participation in Australia between 2015-2020.

METHODS

Publicly available population-level participation data for Australia's National Bowel Cancer Screening Program (NBCSP) were modelled using generalized linear models to quantify screening patterns by remoteness and area-level disadvantage. Bayesian spatial models were used to obtain smoothed estimates of participation across 2,247 small areas during 2019-2020 compared to the national average, and during 2015-2016 and 2017-2018 for comparison. Spatial heterogeneity was assessed using the maximized excess events test.

RESULTS

Overall, screening participation rates was around 44% over the three time-periods. Participation was consistently lower in remote or disadvantaged areas, although heterogeneity was evident within these broad categories. There was strong evidence of spatial differences in participation over all three periods, with little change in patterns between time periods. If the spatial variation was reduced (so low participation areas were increased to the 80th centile), an extra 250,000 screens (4% of total) would have been conducted during 2019-2020.

CONCLUSIONS

Despite having a well-structured evidence-based government funded national bowel cancer screening program, the substantial spatial variation in participation rates highlights the importance of accounting for the unique characteristics of specific geographical regions and their inhabitants. Identifying the reasons for geographical disparities could inform interventions to achieve more equitable access and a higher overall bowel screening uptake.

Disentangling Social Determinants of Health and Rurality in Head and Neck Cancer 2-Year Mortality

Social determinants of health (SDoH) and rurality are known factors that may influence outcomes in head and neck squamous cell carcinoma (HNSCC). Patients residing in remote locations or those with multiple SDoH may encounter barriers to initial diagnosis, adherence to multidisciplinary treatments, and posttreatment surveillance, which may impact their overall survival. However, previous studies have shown mixed results associated with rural residence. The aim of this study is to identify the impact of rurality and SDoH on 2-year survival in HNSCC. The study was conducted using a Head and Neck Cancer Registry at a single institution from June 2018 through July 2022. Rurality, defined by US census scores, and individual measures of SDoH were used. Our results indicate that each additional adverse SDoH factor results in 1.5 times the odds of mortality at 2 years. Individualized measures of SDoH, rather than rurality alone, better reflect patient prognosis in HNSCC.

Defining rurality: an evaluation of rural definitions and the impact on survival estimates

BACKGROUND

Patients with cancer living in rural areas have inferior cancer outcomes; however, studies examining this association use varying definitions of "rural," complicating comparisons and limiting the utility of the results for policy makers and future researchers.

METHODS

Surveillance, Epidemiology, and End Results data (2000-2016) were used to assess risk of cancer mortality and mortality from any cause across 4 definitions of rurality: Urban Influence codes (UIC), National Center for Health Statistics (NCHS), Rural-Urban continuum codes (RUCC), and Index of Relative Rurality. Binary (urban vs rural) and ternary (urban, micropolitan, rural) definitions were evaluated. Multivariable parametric survival models estimated hazards of mortality overall and among 3 cancer groupings: screening related, obesity related, and tobacco related. Definition agreement was also assessed.

RESULTS

Overall, 3 788 273 patients with an incident cancer representing 605 counties were identified. There was little discordance between binary definitions of rural vs urban and moderate agreement at the 3 levels. Adjusted models using binary definitions revealed 15% to 17% greater hazard of cancer mortality in rural compared with urban. At the 3 levels when comparing rural with metropolitan, RUCC and NCHS saw similarly increased hazard ratios; however, Index of Relative Rurality did not. Screening-related cancers saw the highest hazards of mortality and the largest divergence between definitions. Obesity-related and tobacco-related cancers saw similarly increased hazards of mortality at the binary and ternary levels.

CONCLUSIONS

Hazard of death is similar across binary definitions; however, this differed when categorized as ternary or continuous, especially among screening-related cancers. Results suggest that study purpose should direct choice of definitions and categorization.

Linking social and built environmental factors to leisure-time physical activity in rural cancer survivors

BACKGROUND

This study explored associations between social and built environmental factors and leisure-time physical activity (LTPA) in rural cancer survivors (RCS) and whether these associations differed by exercise stage of change (SOC).

METHOD

RCS (n = 219) completed questionnaires assessing LTPA, SOC, and social (social status, connectedness, support) and environmental (home environment, neighborhood environment) factors. Linear regression models examined associations between social and built environmental factors and LTPA and tested for moderation by SOC.

RESULTS

Half (50.7%) of RCS were physically active, and 49.3% were not active. Social factors positively associated with LTPA included subjective social status in the community (B = 89.0, P = .014) and in the United States (B = 181.3, P < .001), social connectedness (B = 122.3, P = .024), and social support for physical activity from family (B = 41.9, P < .001) and friends (B = 44.3, P < .001). Environmental factors positively associated with LTPA included the home environment (B = 111.2, P < .001), perceived environmental support for PA (B = 355.4, P = .004), and neighborhood attributes, including bicycling infrastructure (B = 191.3, P = .003), proximity to recreation facilities (B = 140.1, P = .021), traffic safety (B = 184.5, P = .025), and aesthetics (B = 342.6, P < .001). SOC statistically significantly moderated the association between social status in the United States and LTPA (B = 160.3, P = .031).

CONCLUSIONS

Social and built environmental factors were consistently linked with LTPA and provide context for multilevel interventions promoting LTPA in RCS.

Eliciting Opinions on Health Messaging During the COVID-19 Pandemic: Qualitative Survey Study

BACKGROUND

Effective public health messaging has been necessary throughout the COVID-19 pandemic, but stakeholders have struggled to communicate critical information to the public, especially in different types of locations such as urban and rural areas.

OBJECTIVE

This study aimed to identify opportunities to improve COVID-19 messages for community distribution in rural and urban settings and to summarize the findings to inform future messaging.

METHODS

We purposively sampled by region (urban or rural) and participant type (general public or health care professional) to survey participants about their opinions on 4 COVID-19 health messages. We designed open-ended survey questions and analyzed the data using pragmatic health equity implementation science approaches. Following the qualitative analysis of the survey responses, we designed refined COVID-19 messages incorporating participant feedback and redistributed them via a short survey.

RESULTS

In total, 67 participants consented and enrolled: 31 (46%) community participants from the rural Southeast Missouri Bootheel, 27 (40%) community participants from urban St Louis, and 9 (13%) health care professionals from St Louis. Overall, we found no qualitative differences between the responses of our urban and rural samples to the open-ended questions. Participants across groups wanted familiar COVID-19 protocols, personal choice in COVID-19 preventive behaviors, and clear source information. Health care professionals contextualized their suggestions within the specific needs of their patients. All groups suggested practices consistent with health-literate communications. We reached 83% (54/65) of the participants for message redistribution, and most had overwhelmingly positive responses to the refined messages.

CONCLUSIONS

We suggest convenient methods for community involvement in the creation of health messages by using a brief web-based survey. We identified areas of improvement for future health messaging, such as reaffirming the preventive practices advertised early in a crisis, framing messages such that they allow for personal choice of preventive behavior, highlighting well-known source information, using plain language, and crafting messages that are applicable to the readers' circumstances.

Changes in Dietary Inflammatory Index Score over Time and Cancer Development in Rural Post-Menopausal Women

Inflammation plays a key role in cancer development. As an important modulator of inflammation, the role of diet should be explored. The purpose of this study was to determine the association between diets with a higher inflammatory potential, as measured by the Dietary Inflammatory Index (DII^®), and cancer development in a cohort of rural post-menopausal women. Dietary intake from a randomized controlled trial cohort of rural, post-menopausal women in Nebraska was used to compute energy-adjusted DII (E-DII^TM) scores at baseline and four years later (visit 9). A linear mixed model analysis and multivariate logistic regression evaluated the association between E-DII scores (baseline, visit 9, change score) and cancer status. Of 1977 eligible participants, those who developed cancer (n = 91, 4.6%) had a significantly larger, pro-inflammatory change in E-DII scores (Non-cancer: Δ 0.19 ± 1.43 vs. Cancer: Δ 0.55 ± 1.43, p = 0.02). After adjustment, odds of cancer development were over 20% higher in those with a larger change (more pro-inflammatory) in E-DII scores than those with smaller E-DII changes (OR = 1.21, 95% CI [1.02, 1.42], p = 0.02). Shifting to a more pro-inflammatory diet pattern over four years was associated with increased odds of cancer development, but not with E-DII at baseline or visit 9 alone.

Geographical and spatial disparities in the incidence and survival of rare cancers in Australia

Rare cancers collectively account for around a quarter of cancer diagnoses and deaths. However, epidemiological studies are sparse. We describe spatial and geographical patterns in incidence and survival of rare cancers across Australia using a population-based cancer registry cohort of rare cancer cases diagnosed among Australians aged at least 15 years, 2007 to 2016. Rare cancers were defined using site- and histology-based categories from the European RARECARE study, as individual cancer types having crude annual incidence rates of less than 6/100 000. Incidence and survival patterns were modelled with generalised linear and Bayesian spatial Leroux models. Spatial heterogeneity was tested using the maximised excess events test. Rare cancers (n = 268 070) collectively comprised 22% of all invasive cancer diagnoses and accounted for 27% of all cancer-related deaths in Australia, 2007 to 2016 with an overall 5-year relative survival of around 53%. Males and those living in more remote or more disadvantaged areas had higher incidence but lower survival. There was substantial evidence for spatial variation in both incidence and survival for rare cancers between small geographical areas across Australia, with similar patterns so that those areas with higher incidence tended to have lower survival. Rare cancers are a substantial health burden in Australia. Our study has highlighted the need to better understand the higher burden of these cancers in rural and disadvantaged regions where the logistical challenges in their diagnosis, treatment and support are magnified.

Disparities in cancer incidence by rurality in California

BACKGROUND

Cancer rates in rural areas across the United States have different patterns than in urban areas. This study examines associations between rurality and incidence for the top 5 cancers in California and evaluates whether these associations vary jointly by sex, race, and ethnicity.

METHODS

We used 2015-2019 California Cancer Registry data to compare incidence rate ratios (IRRs) and trends for breast, prostate, lung, colorectal, and skin (melanoma) cancers. We leveraged census tract aggregation zones and 7 levels of percentage rural population (0%, >0% to <10%, 10% to <20%, 20% to <30%, 30% to <40%, 40% to <50%, and 50+%).

RESULTS

Zones with higher proportions of rural population were significantly associated with lower incidence of female breast cancer and prostate cancer, though the trends were not statistically significant overall. Zones with higher proportions of rural population were significantly associated with higher incidence of lung cancer and melanoma. There were no statistically significant trends for colorectal cancer overall. Comparing areas with 50% and over rural population with areas with 0% rural population, the IRR for lung cancer in Hispanic females was higher (IRR = 1.43, 95% confidence interval [CI] = 1.17 to 1.74) than in Hispanic males (IRR = 0.90, 95% CI = 0.72 to 1.11). Also, in areas with 50% or more rural population, the IRR for melanoma was higher in Hispanic females (IRR = 1.75, 95% CI = 1.23 to 2.45) than non-Hispanic White females (IRR = 0.87, 95% CI = 0.80 to 0.95).

CONCLUSIONS

Our findings show that rurality is associated with cancer incidence and underscore the importance of jointly examining rural disparities with sex, race, and ethnicity by cancer site.

Similarities and differences across the underlying dimensions of social functioning in rural and nonrural cancer survivors: A mixed-methods study

PURPOSE

For cancer survivors, social functioning greatly influences other quality of life dimensions. While there is potential for differences in social functioning to vary as a function of geographic residence, few studies examine the social functioning of rural cancer survivors specifically. This study aims to help fill this gap.

METHODS

This was an embedded mixed-methods study where all participants completed a questionnaire, and some were purposively selected to complete an interview to gather more information about social functioning (ie, social roles, activities, network, support, and constraint). Participants (n = 93; 63% rural) were recruited through a state cancer registry and cancer care facility. Participants were predominately White, non-Hispanic (92.47%), roughly half female (54.84%), and on average, diagnosed in the past two years (SD = 1.68), and 61.45 (SD = 10.87) years old.

FINDINGS

Few differences in the social functioning of rural and nonrural participants were found on questionnaires, though rural participants reported larger networks and more overall support. Across groups, common themes in the interview data were the experience of both social support (eg, instrumental support) and social constraint (eg, others minimizing participants' problems or sharing their own negative experiences).

CONCLUSIONS

This was the first cancer survivorship study to thoroughly examine social functioning by geographic residence. Rural cancer survivors described some unique strengths, but major group differences were not apparent. All participants highlighted situations when others, even with good intentions, were unhelpful to them. Future interventions to improve social functioning could work to dispel the belief that cancer survivors should handle their cancer on their own.

A Rapid Systematic Review on the Experiences of Cancer Survivors Residing in Rural Areas during the COVID-19 Pandemic

The COVID-19 pandemic has caused considerable disruption to cancer care and may have exacerbated existing challenges already faced by cancer survivors from rural areas. This has created a need for a rapid evidence synthesis to inform the development of tailored interventions that address the specific needs of rural cancer survivors who continue to be affected by the pandemic. The review was conducted following guidance from the Cochrane Rapid Review Methods Group. Database searches were performed via the EBSCOHost interface (includes MEDLINE, CINAHL, PsycINFO) on 25 May 2022 and supplemented with searches on Google Scholar. Peer-reviewed articles published after March 2020 that reported primary data on the experiences of cancer survivors residing in rural and remote settings during the pandemic were included. Findings were tabulated and written up narratively. Fourteen studies were included. The COVID-19 pandemic had a mostly detrimental impact on the experiences of rural cancer survivors. People's individual coping mechanisms were challenging for a range of reasons. Specifically, the pandemic impacted on their ability to access testing, treatment, check-ups and supportive care, their ability to maintain and access social support with close friends and family, as well as negative consequences to their finances and emotional wellbeing with some reporting feelings of psychological distress including depression and anxiety. This review provides important insight into the experiences of rural cancer survivors that may help inform tailored support in line with the needs and challenges faced because of the pandemic.

Access to paediatric oncology centres in Switzerland: Disparities across rural-urban and Swiss-foreigners cohorts

OBJECTIVE

In face of disparities in access to cancer care, it has been proposed to measure accessibility and to explore policy strategies for mitigating inequality of access. We aimed to determine the accessibility of Swiss paediatric oncology centres.

METHODS

We employed spatial accessibility analysis, calculating driving time to nearest facility. Four data types were used: disaggregated population data, administrative data, street network data and addresses of centres. Besides analysing general accessibility, we compared access of urban versus rural areas and of Swiss citizens versus foreign residents and evaluated designating a new centre to improve accessibility.

RESULTS

Overall, 97.4% could reach the nearest centre within 120 min (95.0% < 90 min, 86.5% < 60 min, 48.5% < 30 min). Accessibility could most effectively be improved by a new centre in Sion (city in the southwest of Switzerland). Access in urban areas was better than in rural areas. In urban areas, access of European Union/European Free Trade Association (EU/EFTA) and non-European residents was better than access of Swiss citizens and residents from non-EU European countries.

CONCLUSION

Access is satisfactory. However, our study presents high-resolution insights which could serve as points of leverage for policymakers to mitigate inequalities by designating a new centre and to evaluate potential benefits of centralisation.

Receipt of Out-of-State Telemedicine Visits Among Medicare Beneficiaries During the COVID-19 Pandemic

Question

How was out-of-state telemedicine used during the COVID-19 pandemic?

Findings

In this cross-sectional study of telemedicine visits in the first half of 2021 among patients with Medicare, 422 547 patients had an out-of-state telemedicine visit; these visits were most common among those who lived near a state border and were largely for primary care and mental health treatment. In 62.6% of all out-of-state visits, a prior in-person visit occurred between the same patient and clinician.

Meaning

Limitations on out-of-state telemedicine care may disrupt many existing patient-clinician relationships in primary care and mental health treatment.

Importance

Early in the COVID-19 pandemic, states implemented temporary changes allowing physicians without a license in their state to provide care to their residents. There is an ongoing debate at both the federal and state levels on whether to change licensure rules permanently to facilitate out-of-state telemedicine use.

Objective

To describe out-of-state telemedicine use during the pandemic.

Design, Setting, and Participants

This cross-sectional study of telemedicine visits included all patients with traditional Medicare from January through June 2021.

Main Outcomes and Measures

Telemedicine visits from January through June 2021 where the patient’s home address and the physician’s practice address were in different states.

Results

In describing which patients and specialties were using out-of-state telemedicine, we focused on the period between January to June 2021. We chose this period because it was after the turmoil of the early pandemic, when vaccines became widely available and the health care system had stabilized, but before many of the temporary licensing regulations began to lapse by mid-2021. In the first half of 2021, there were 8 392 092 patients with a telemedicine visit and, of these, 422 547 (5.0%) had 1 or more out-of-state telemedicine visits. Those who lived in a county close to a state border (within 15 miles) accounted for 57.2% of all out-of-state telemedicine visits. Among the out-of-state visits in this time period, 64.3% were with a primary care or mental health clinician. For 62.6% of all out-of-state visits, a prior in-person visit occurred between the same patient and clinician between March 2019 and the visit. The demographics and conditions treated were similar for within-state and out-of-state telemedicine visits, with several notable exceptions. Among those with a telemedicine visit, people in rural communities were more likely to receive out-of-state telemedicine care (33.8% vs 21.0%), and there was high of out-of-state telemedicine use for cancer care (9.8% of all telemedicine visits for cancer care).

Conclusions and Relevance

The findings of this cross-sectional study suggest that licensure restrictions of out-of-state telemedicine would have had the largest effect on patients who lived near a state border, those in rural locales, and those who received primary care or mental health treatment.
