Receipt of cancer screening services: surprising results for some rural minorities

Urban relatives ameliorate survival disparities for genitourinary cancer in rural patients

INTRODUCTION

Patients living in rural areas have worse cancer-specific outcomes. This study examines the effect of family-based social capital on genitourinary cancer survival. We hypothesized that rural patients with urban relatives have improved survival relative to rural patients without urban family.

METHODS

We examined rural and urban based Utah individuals diagnosed with genitourinary cancers between 1968 and 2018. Familial networks were determined using the Utah Population Database. Patients and relatives were classified as rural or urban based on 2010 rural-urban commuting area codes. Overall survival was analyzed using Cox proportional hazards models.

RESULTS

We identified 24,746 patients with genitourinary cancer with a median follow-up of 8.72 years. Rural cancer patients without an urban relative had the worst outcomes with cancer-specific survival hazard ratios (HRs) at 5 and 10 years of 1.33 (95% CI 1.10-1.62) and 1.46 (95% CI 1.24-1.73), respectively relative to urban patients. Rural patients with urban first-degree relatives had improved survival with 5- and 10-year survival HRs of 1.21 (95% CI 1.06-1.40) and 1.16 (95% CI 1.03-1.31), respectively.

CONCLUSIONS

Our findings suggest rural patients who have been diagnosed with a genitourinary cancer have improved survival when having relatives in urban centers relative to rural patients without urban relatives. Further research is needed to better understand the mechanisms through which having an urban family member contributes to improved cancer outcomes for rural patients. Better characterization of this affect may help inform policies to reduce urban-rural cancer disparities.

Determining the association of rurality and cardiovascular disease among prostate cancer survivors

PURPOSE

Rural disparities in prostate cancer survivorship and cardiovascular disease remain. Prostate cancer treatment also contributes to worse cardiovascular disease outcomes. Our objective was to determine whether rural-urban differences in cardiovascular outcomes contribute to disparities in prostate cancer survivorship.

MATERIALS AND METHODS

Data were collected from the Utah Population Database. Rural and urban prostate cancer survivors were matched by diagnosis year and age. Cox proportional hazards models were used to estimate hazard ratios for cardiovascular disease (levels 1-3) based on rural-urban classification, while controlling for demographic and socioeconomic characteristics. We identified 3,379 rural and 16,253 urban prostate cancer survivors with a median follow-up of 9.3 years.

RESULTS

Results revealed that rural survivors had a lower risk of hypertension (HR 0.90), diseases of arteries (HR 0.92), and veins (HR 0.92) but a higher risk of congestive heart failure (HR 1.17). Interactions between level 2 cardiovascular diseases and rural/urban status, showed that diseases of the heart had a distinct between-group relationship for all-cause (P = 0.005) and cancer-specific mortality (P = 0.008).

CONCLUSIONS

This study revealed complex relationships between rural-urban status, cardiovascular disease, and prostate cancer. Rural survivors were less likely to be diagnosed with screen-detected cardiovascular disease but more likely to have heart failure. Further, the relationship between cardiovascular disease and survival was different between rural and urban survivors. It may be that our findings underscore differences in healthcare access where rural patients are less likely to be screened for preventable cardiovascular disease and have worse outcomes when they have a major cardiovascular event.

Small-Area Geographic and Socioeconomic Inequalities in Colorectal Cancer in Cyprus

Colorectal cancer (CRC) is one of the leading causes of death and morbidity worldwide. To date, the relationship between regional deprivation and CRC incidence or mortality has not been studied in the population of Cyprus. The objective of this study was to analyse the geographical variation of CRC incidence and mortality and its possible association with socioeconomic inequalities in Cyprus for the time period of 2000-2015. This is a small-area ecological study in Cyprus, with census tracts as units of spatial analysis. The incidence date, sex, age, postcode, primary site, death date in case of death, or last contact date of all alive CRC cases from 2000-2015 were obtained from the Cyprus Ministry of Health's Health Monitoring Unit. Indirect standardisation was used to calculate the sex and age Standardise Incidence Ratios (SIRs) and Standardised Mortality Ratios (SMRs) of CRC while the smoothed values of SIRs, SMRs, and Mortality to Incidence ratio (M/I ratio) were estimated using the univariate Bayesian Poisson log-linear spatial model. To evaluate the association of CRC incidence and mortality rate with socioeconomic deprivation, we included the national socioeconomic deprivation index as a covariate variable entering in the model either as a continuous variable or as a categorical variable representing quartiles of areas with increasing levels of socioeconomic deprivation. The results showed that there are geographical areas having 15% higher SIR and SMR, with most of those areas located on the east coast of the island. We found higher M/I ratio values in the rural, remote, and less dense areas of the island, while lower rates were observed in the metropolitan areas. We also discovered an inverted U-shape pattern in CRC incidence and mortality with higher rates in the areas classified in the second quartile (Q2-areas) of the socioeconomic deprivation index and lower rates in rural, remote, and less dense areas (Q4-areas). These findings provide useful information at local and national levels and inform decisions about resource allocation to geographically targeted prevention and control plans to increase CRC screening and management.

HPV self-collection: what are we waiting for? Exploration of attitudes from frontline healthcare providers

OBJECTIVE

Polymerase chain reaction based human papilloma virus (HPV) self-collection for cervical cancer screening is well established. It is utilized worldwide, accepted by patients, is cost-effective, has comparable sensitivity to provider-collected samples, and increases screening rates, however clinical practice in the United States has not shifted to include HPV self-collection. This study sought to examine provider knowledge and attitudes to better understand why HPV self-collection is not being utilized.

METHODS

An observational, qualitative study was conducted. Data were collected with semi-structured focus groups and individual interviews with Oregon healthcare providers. Focus groups and interviews were continued until data saturation was achieved. A grounded theory method was used for analysis, a cyclical process of coding data, memo-writing, and theoretical sampling to the point of saturation.

RESULTS

Eighteen healthcare providers participated in the focus group and interviews. They represented 14 of 36 counties across Oregon and 50% were physicians, 33% were nurse practitioners, and 94% worked within family medicine. All providers performed cervical cancer screening according to current American Society for Colposcopy and Cervical Pathology guidelines. Five overarching themes emerged: provider concerns, clinical and provider barriers, patient perspective and barriers, process-based themes, and barriers to cervical cancer screening. Nearly all providers stated they will offer HPV self-collection to most of their patients once available.

CONCLUSION

While providers identified concerns and barriers for initiating HPV self-collection, there was a strong desire to implement HPV self-collection and acceptance within patient populations was assumed. Providers indicated the need for HPV self-collection to be incorporated into national screening guidelines along with best practices on how to successfully implement this modality to further increase cervical cancer screening rates.

Preventive Health Screening in Veterans Undergoing Bariatric Surgery

INTRODUCTION

Individuals with obesity are vulnerable to low rates of preventive health screening. Veterans with obesity seeking bariatric surgery are also hypothesized to have gaps in preventive health screening. Evaluation in a multidisciplinary bariatric surgery clinic is a point of interaction with the healthcare system that could facilitate improvements in screening.

METHODS

This is a retrospective cohort study of 381 consecutive patients undergoing bariatric surgery at a Veterans Affairs Hospital from January 2010 to October 2021. Age- and sex-appropriate health screening rates were determined at initial referral to a multidisciplinary bariatric surgery clinic and at the time of surgery. Rates of guideline concordance at both time points were compared using McNemar's test. Univariate and multivariate analyses were performed to identify the risk factors for nonconcordance.

RESULTS

Concordance with all recommended screening was low at initial referral and significantly improved by time of surgery (39.1%‒63.8%; p<0.001). Screening rates significantly improved for HIV (p<0.001), cervical cancer (p=0.03), and colon cancer (p<0.001). Increases in BMI (p=0.005) and the number of indicated screening tests (p=0.029) were associated with reduced odds of concordance at initial referral. Smoking history (p=0.012) and increasing distance to the nearest Veterans Affairs Medical Center (p=0.039) were associated with reduced odds of change from nonconcordance at initial referral to concordance at the time of surgery.

CONCLUSIONS

Rates of preventive health screening in Veterans with obesity are low. A multidisciplinary bariatric surgery clinic is an opportunity to improve preventive health screening in Veterans referred for bariatric surgery.

Help wanted: low provider density is associated with advanced stage cervical cancer

BACKGROUND

Patients in rural areas have a higher incidence of cervical cancer with increased rates of metastatic disease than their urban counterparts.

OBJECTIVE

To evaluate whether medical provider density, acting as a surrogate for screening availability, is associated with the incidence of cervical cancer or proportion diagnosed with advanced stage disease.

METHODS

Cervical cancer cases by county from 2015 were retrieved from the SEER database. The numbers of primary obstetric-gynecologists (OB-GYN), family practice, and internal medicine providers were obtained from the Area Health Resource File, and population estimates for each county were used to calculate provider to resident ratios. Spearman rank correlations were used to compare the number of providers per 100 000 residents with the overall incidence of cervical cancer as well as the proportion diagnosed at an advanced stage. Multivariable logistic regression was performed to assess factors independently associated with advanced stage disease, accounting for county of residence. Mortality was compared across different OB-GYN provider density categories.

RESULTS

A total of 3505 cases of cervical cancer from 405 counties were included. Spearman correlation demonstrated a significant inverse association between the number of OB-GYN providers per 100 000 residents and the incidence of cervical cancer (p<0.0001) as well as the proportion diagnosed at an advanced stage (p=0.003). Compared with those living in counties with ≤5 OB-GYN providers per 100 000 residents, those living in counties with >10 providers had a 29% reduction in the odds of presenting with advanced stage disease (OR=0.71; 95% CI 0.55 to 0.91). An inverse association between cervical cancer-related mortality and OB-GYN provider density was also noted.

CONCLUSION

A significant inverse correlation between provider density and incidence of cervical cancer, proportion with advanced stage disease, and cervical cancer-related mortality was observed. Increasing provider density in these underserved, high-risk areas may improve timely cancer detection.

Cancer disparities in the context of rurality: risk factors and screening across various U.S. rural classification codes

PURPOSE

Prior cancer research is limited by inconsistencies in defining rurality. The purpose of this study was to describe the prevalence of cancer risk factors and cancer screening behaviors across various county-based rural classification codes, including measures reflecting a continuum, to inform our understanding of cancer disparities according to the extent of rurality.

METHODS

Using an ecological cross-sectional design, we examined differences in cancer risk factors and cancer screening behaviors from the Behavioral Risk Factor Surveillance System and National Health Interview Survey (2008-2013) across rural counties and between rural and urban counties using four rural-urban classification codes for counties and county-equivalents in 2013: U.S. Office of Management and Budget, National Center for Health Statistics, USDA Economic Research Service's rural-urban continuum codes, and Urban Influence Codes.

RESULTS

Although a rural-to-urban gradient was not consistently evident across all classification codes, the prevalence of smoking, obesity, physical inactivity, and binge alcohol use increased (all p_trend < 0.03), while colorectal, cervical and breast cancer screening decreased (all p_trend < 0.001) with increasing rurality. Differences in the prevalence of risk factors and screening behaviors across rural areas were greater than differences between rural and urban counties for obesity (2.4% vs. 1.5%), physical activity (2.9% vs. 2.5%), binge alcohol use (3.4% vs. 0.4%), cervical cancer screening (6.8% vs. 4.0%), and colorectal cancer screening (4.4% vs. 3.8%).

CONCLUSIONS

Rural cancer disparities persist across multiple rural-urban classification codes, with marked variation in cancer risk factors and screening evident within rural regions. Focusing only on a rural-urban dichotomy may not sufficiently capture subpopulations of rural residents at greater risk for cancer and cancer-related mortality.

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

Cancer care disparities among rural populations are increasingly documented and may be worsening, likely because of the impact of rurality on access to state-of-the-art cancer prevention, diagnosis, and treatment services, as well as higher rates of risk factors such as smoking and obesity. In 2018, the American Society of Clinical Oncology undertook an initiative to understand and address factors contributing to rural cancer care disparities. A key pillar of this initiative was to identify knowledge gaps and promote the research needed to understand the magnitude of difference in outcomes in rural vs nonrural settings, the drivers of those differences, and interventions to address them. The purpose of this review is to describe continued knowledge gaps and areas of priority research to address them. We conducted a comprehensive literature review by searching the PubMed (Medline), Embase, Web of Science, and Cochrane Library databases for studies published in English between 1971 and 2021 and restricted to primary reports from populations in the United States and abstracted data to synthesize current evidence and identify continued gaps in knowledge. Our review identified continuing gaps in the literature regarding the underlying causes of rural-urban disparities in cancer outcomes. Rapid advances in cancer care will worsen existing disparities in outcomes for rural patients without directed effort to understand and address barriers to high-quality care in these areas. Research should be prioritized to address ongoing knowledge gaps about the drivers of rurality-based disparities and preventative and corrective interventions.

Rural Latino health and the built environment: a systematic review

Objective: This study systematically reviewed literature examining the influence of the rural built environment on Latinos' health outcomes and behaviour in the United States. A secondary aim of the study was to identify strategies developed to address challenges in the rural built environment affecting Latinos' health.Design: This study followed the reporting guidelines set forth by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Articles included in the final analysis clearly linked Latino health outcomes to characteristics of the rural built environment.Results: Of the nearly 2,500 articles identified in the initial search, the final review included approximately 146 full-text sources. The majority of the articles focused on aspects of Latinos' physical (n = 68), behavioural (n = 43), and mental health (n = 23).Conclusions: Rural Latino neighbourhoods in the United States possess limited access to health care, internet, transportation, and recreation infrastructure, which negatively impacts health outcomes and behaviours. Strategies developed to mitigate these issues include but are not limited to: the use of telecommunications to distribute health information; the use of community health workers and mobile clinics to increase awareness and availability of select health services; the use of worksite trainings and adaptations to the workplace; and the promotion of safety net programmes, such as the Supplemental Nutrition Programme for Women, Infants and Children (WIC). This review supports the need for a more robust research agenda documenting the health experiences of rural Latinos of various nationalities, age groups, and genders.

Urbanicity, Health, and Access to Services for People With Intellectual Disability and Developmental Disabilities

Previous research suggests that residence in non-metropolitan areas is associated with lower access to preventive care and poorer health. However, this research has been largely restricted to the general population, despite data demonstrating disparities in health status and access to healthcare services for people with intellectual and developmental disabilities (IDD). The current study examined several hypotheses involving the effects of rurality on access to preventive healthcare and services and health status: (1) individuals in non-metropolitan areas will have lower preventive healthcare utilization, (2) individuals in non-metropolitan areas will have poorer health outcomes, and (3) individuals in non-metropolitan areas will have poorer access to services. The current study uses data from the National Core Indicators (NCI) Adult Consumer Survey 2015-2016: Final Report which included Rural-Urban Commuting Area (RUCA) Codes for the first time. Results of logistic regression suggest that, despite connection to disability services, the health status and access to preventive healthcare services of people with IDD generally follow patterns similar to those observed in the general population. Namely, people with IDD in non-metropolitan areas have decreased access to healthcare services, preventive healthcare utilization, and health status. Despite some exceptions, it appears effects of rurality are not completely mitigated by current state and federal efforts.

Differences in Breast and Colorectal Cancer Screening Adherence Among Women Residing in Urban and Rural Communities in the United States

Importance

Screening for breast and colorectal cancer has resulted in reductions in mortality; however, questions remain regarding how these interventions are being diffused to all segments of the population. If an intervention is less amenable to diffusion, it could be associated with disparities in mortality rates, especially in rural vs urban areas.

Objectives

To compare the prevalence of breast and colorectal cancer screening adherence and to identify factors associated with screening adherence among women residing in rural vs urban areas in the United States.

Design, Setting, and Participants

This population-based cross-sectional study of women aged 50 to 75 years in 11 states was conducted from 2017 to 2020.

Main Outcomes and Measures

Adherence to cancer screening based on the US Preventative Services Task Force guidelines. For breast cancer screening, women who had mammograms in the past 2 years were considered adherent. For colorectal cancer screening, women who had (1) a stool test in the past year, (2) a colonoscopy in the past 10 years, or (3) a sigmoidoscopy in the past 5 years were considered adherent. Rural status was coded using Rural Urban Continuum Codes, and other variables were assessed to identify factors associated with screening.

Results

The overall sample of 2897 women included 1090 (38.4%) rural residents; 2393 (83.5%) non-Hispanic White women; 263 (9.2%) non-Hispanic Black women; 68 (2.4%) Hispanic women; 1629 women (56.2%) aged 50 to 64 years; and 712 women (24.8%) with a high school education or less. Women residing in urban areas were significantly more likely to be adherent to colorectal cancer screening compared with women residing in rural areas (1429 [82%] vs 848 [78%]; P = .01), whereas the groups were equally likely to be adherent to breast cancer screening (1347 [81%] vs 830 [81%]; P = .78). Multivariable mixed-effects logistic regression analyses confirmed that rural residence was associated with lower odds of being adherent to colorectal cancer screening (odds ratio [OR], 0.81; 95% CI, 0.66-0.99, P = .047). Non-Hispanic Black race was associated with adherence to breast cancer screening guidelines (OR, 2.85; 95% CI, 1.78-4.56; P < .001) but not colorectal cancer screening guidelines.

Conclusions and Relevance

In this cross-sectional study, women residing in rural areas were less likely to be adherent to colorectal cancer screening guidelines but were similarly adherent to breast cancer screening. This suggests that colorectal cancer screening, a more recent intervention, may not be as available in rural areas as breast cancer screening, ie, colorectal screening has lower amenability.

Value-Based Pay-for-Performance Gaps in the Care Delivery Framework for a Large-Scale Health System

Many health systems are engaging in pay-for-performance agreements with payers that focus primarily on improving ambulatory preventive screenings. These also are referred to as gaps in care. Gaps in care are typically measured by the Healthcare Effectiveness Data and Information Set measures of health care quality. To address gaps in care effectively, the physician-led Gaps in Care program at Northwell Health works to improve processes related to measurement, data attribution, patient outreach, and patient engagement. Following a structured framework to address patient gaps in care is a successful strategy for accomplishing complex value-based care delivery.

Cervical cancer risk and screening among women seeking assistance with basic needs

BACKGROUND

In the United States, more than half of cervical cancers occur in women who are inadequately screened. Interventions to improve access to cervical cancer preventive care is critical to reduce health inequities.

OBJECTIVE

This study aimed to evaluate the need for cervical cancer screening among women seeking assistance with basic needs and to assess best approaches to facilitate Papanicolaou test referral.

STUDY DESIGN

This study is a secondary analysis of a randomized controlled trial of low-income female callers to 2-1-1 Missouri, a helpline for local health and social services. The need for cervical cancer screening was assessed. Callers were randomized to 1 of 3 arms, each providing a Papanicolaou test referral: verbal referral only, verbal referral and tailored print reminder, or verbal referral and navigator. The primary outcome was contacting a Papanicolaou test referral 1 month following intervention. Student t tests or Mann-Whitney U tests were used to analyze significant differences in continuous variables, whereas Fisher exact or χ² tests were used for categorical variables. We stratified by number of unmet basic needs (0-1 vs ≥2) and compared success of contacting a Papanicolaou test referral among study groups (verbal referral vs tailored reminder vs navigator) using the Fisher exact test and χ² test, respectively. Multivariate logistic regression was used to assess risk factors for nonadherence for Papanicolaou test at baseline and at 1 month follow-up, adjusting for race and ethnicity, age, insurance status, self-rated health, smoking, and study group.

RESULTS

Among 932 female callers, 250 (26.8%) needed cervical cancer screening. The frequency of unmet basic needs was high, the most common being lack of money for unexpected expenses (91.2%) and necessities, such as food, shelter, and clothing (73.2%). Among those needing a Papanicolaou test, 211 women received screening referrals. Women in the navigator group (21 of 71, 29.6%) reported higher rates of contacting a Papanicolaou test referral than those exposed to verbal referral only (11/73, 15.1%) or verbal referral and tailored print reminder (9/67, 13.4%) (P=.03). Among 176 women with ≥2 unmet needs who received a Papanicolaou test referral, the provision of a navigator remained associated with contacting the referral (navigator [33.9%] vs verbal referral [17.2%] vs tailored reminder [10.2%]; P=.005). Assignment to the navigator group (adjusted odds ratio, 3.4; 95% confidence interval, 1.4-8.5) and nonwhite race (adjusted odds ratio, 2.0; 95% confidence interval, 1.5-2.8) were independent predictors of contacting a Papanicolaou test referral.

CONCLUSION

Low-income women seeking assistance with basic needs often lack cervical cancer screening. Health navigators triple the likelihood that women will make contact with Papanicolaou test services, but most 2-1-1 callers still fail to schedule Papanicolaou testing despite assistance from navigators. Interventions beyond health navigators are needed to reduce cervical cancer disparities.

The Intersection of Rural Residence and Minority Race/Ethnicity in Cancer Disparities in the United States

One in every twenty-five persons in America is a racial/ethnic minority who lives in a rural area. Our objective was to summarize how racism and, subsequently, the social determinants of health disproportionately affect rural racial/ethnic minority populations, provide a review of the cancer disparities experienced by rural racial/ethnic minority groups, and recommend policy, research, and intervention approaches to reduce these disparities. We found that rural Black and American Indian/Alaska Native populations experience greater poverty and lack of access to care, which expose them to greater risk of developing cancer and experiencing poorer cancer outcomes in treatment and ultimately survival. There is a critical need for additional research to understand the disparities experienced by all rural racial/ethnic minority populations. We propose that policies aim to increase access to care and healthcare resources for these communities. Further, that observational and interventional research should more effectively address the intersections of rurality and race/ethnicity through reduced structural and interpersonal biases in cancer care, increased data access, more research on newer cancer screening and treatment modalities, and continued intervention and implementation research to understand how evidence-based practices can most effectively reduce disparities among these populations.

Given a choice between self-sampling at home for HPV testing and standard of care screening at the clinic, what do African American women choose? Findings from a group randomized controlled trial

The goals of this study were to: (1) evaluate adherence to cervical cancer screening using a patient-centered approach that provided a choice of self-sampling at home for human papillomavirus (HPV) testing or standard of care screening at the local health department ('Choice') versus only standard of care screening at the local health department ('SCS') among un/under-screened African-American women; and (2) examine whether women given a choice were more likely to choose and adhere to self-sampling for HPV testing. We conducted a group randomized trial among un/under-screened African-American women in the Mississippi Delta, with "town" as the unit of randomization (12 towns). Both interventions (i.e., 'Choice' versus 'SCS') were delivered by Community Health Workers (CHWs) through a door-to-door approach. A total of 335 women were enrolled in the study from 2016 to 2019. The 'Choice' arm had a significantly (p = 0.005) higher adherence to screening compared to the 'SCS' arm after adjusting for the cluster effect and other relevant behavioral variables. Participants in the 'Choice' arm were 5.62 (95% CI 1.71-18.44) times more likely to adhere to cervical cancer screening compared to participants in the 'SCS' arm. Women in the 'Choice' arm were significantly more likely to choose (76%) and adhere to self-sampling at home for HPV testing (48% adherence) compared to standard of care screening at the local health department (7.5% adherence). A theory-driven, CHW-led intervention can effectively promote cervical cancer screening among un/under-screened African-American women in a rural setting when women are provided with a choice between two screening modalities. Clinical Trials Registration: NCT03713710.

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

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

Risk Behaviors Correlate with Higher Prevalence of Papanicolaou, Human Papillomavirus, and Human Immunodeficiency Virus Screening Among Women in the United States

Introduction: This study assesses whether women with human immunodeficiency virus (HIV) risk behavior have higher Papanicolaou (Pap), human papillomavirus (HPV), and HIV testing, and whether the level of selected variables associated with HIV risk behavior correlate with greater testing. Association between HIV risk situations and HPV vaccination is also evaluated. Methods: A cross-sectional assessment was performed in women at age 18 years and older completing the 2018 Behavioral Risk Factor Surveillance System (BRFSS) survey. Independent variables considered and adjusted for, included age, race/ethnicity, marital status, education, annual household income, smoking status, and health care status. Results: Prevalence of a Pap test in the past 3 years was 66.2%, of HPV test in the past 5 years was 40.2%, and of HIV test ever was 41.9%. HIV risk situations applied to 4.9% women (15.2% in ages 18-24, 7.2% in 25-44, 1.9% in 45-64, and 0.6% in 65 years and older). Adjusted odds (95% confidence interval) of a Pap, HPV, or HIV test according to HIV risk behavior status were 1.5 (1.3-1.8), 1.6 (1.4-1.8), and 2.6 (2.3-2.9), respectively. The positive association between HIV risk behavior and Pap testing depends on marital status. HIV risk behavior significantly correlates with several variables, which, in turn, correlate with testing. There was no association between HIV risk behavior and HPV vaccination. Conclusions: Women with HIV risk behavior are more likely to pursue Pap, HPV, and HIV testing. The significant positive associations are largest for HIV testing and smallest for Pap testing, after adjustment for the selected variables. HIV risk behavior is not associated with HPV vaccination.

Improving Colorectal Cancer Screening in a Rural Setting: A Randomized Study

INTRODUCTION

Colorectal cancer screening has been shown to prevent or detect early colorectal cancer and reduce mortality; yet, adherence to screening recommendations remains low, particularly in rural settings.

STUDY DESIGN

RCT.

SETTING/PARTICIPANTS

Adults (n=7,812) aged 50-75 years and due for colorectal cancer screening in a largely rural health system were randomly assigned to either the intervention (n=3,906) or the control (n=3,906) group in September 2016, with analysis following through 2018.

INTERVENTION

A mailed motivational messaging screening reminder letter with an option to call and request a free at-home fecal immunochemical screening test (intervention) or the standard invitation letter detailing that the individual was due for screening (control). Multifaceted motivational messaging emphasized colorectal cancer preventability and the ease and affordability of screening, and communicated a limited supply of test kits.

MAIN OUTCOME MEASURES

Colorectal cancer screening participation within 6 months after mailed invitation was ascertained from the electronic medical record.

RESULTS

Colorectal cancer screening participation was significantly improved in the intervention (30.1%) vs the usual care control group (22.5%; p<0.001). Individuals randomized to the intervention group had 49% higher odds of being screened over follow-up than those randomized to the control group (OR=1.49, 95% CI=1.34, 1.65). A total of 13.2 screening invitations were needed to accomplish 1 additional screening over the usual care. Of the 233 fecal immunochemical test kits mailed to participants, 154 (66.1%) were returned, and 18 (11.7%) tested positive.

CONCLUSIONS

A mailed motivational messaging letter with a low-cost screening alternative increased colorectal cancer screening in this largely rural community with generally poor adherence to screening recommendations. Mailed colorectal cancer screening reminders using motivational messaging may be an effective method for increasing screening and reducing rural colorectal cancer disparities.

Do mobile units contribute to spatial accessibility to mammography for uninsured women?

Limited spatial accessibility to mammography, and socioeconomic barriers (e.g., being uninsured), may contribute to rural disparities in breast cancer screening. Although mobile mammography may contribute to population-level access, few studies have investigated this relationship. We measured mammography access for uninsured women using the variable two-step floating catchment area (V2SFCA) method, which estimates access at the local level using estimated potential supply and demand. Specifically, we measured supply with mammography machine certifications in 2014 from FDA and brick-and-mortar and mobile facility data from the community-based Breast Screening and Patient Navigation (BSPAN) program. We measured potential demand using Census tract-level estimates of female residents aged 45-74 from 5-year 2012-2016 American Community Survey data. Using the sign test, we compared mammography access estimates based on 3 facility groupings: FDA-certified, program brick-and-mortar only, and brick-and-mortar plus mobile. Using all mammography facilities, accessibility was high in urban Dallas-Ft. Worth, low for the ring of adjacent counties, and high for rural counties outlying this ring. Brick-and-mortar-based estimates were lower for the outlying ring, and mobile-unit contribution to access was observed more in urban tracts. Weak mobile-unit contribution across the study area may indicate suboptimal dispatch of mobile units to locations. Geospatial methods could identify the optimal locations for mobile units, given existing brick-and-mortar facilities, to increase access for underserved areas.

National organization of uterine cervical cancer screening and social inequality in France

Some of the inequality in uterine cervical cancer (UCC) screening uptake are due to the socioeconomic deprivation of women. A national organized screening programme has proven to be effective in increasing the uptake, but may increase socioeconomic inequality. Therefore, we compared inequality in uptake of UCC screening between two French departments, one of which is experimenting an organized screening programme. We used reimbursement data from the main French health insurance scheme to compare screening rates in the municipalities of the two departments over a three-year period. The experimental department had higher screening rates, but the increase in deprivation in municipalities had a greater effect on the decrease in participation in this department. Moreover, while screening rates were higher in urban areas, the negative effect of deprivation on participation was greater in rural areas. Although these departments were compared at the same time under different conditions, socioeconomic inequality between them may have been greater before the experimentation started. However, screening may have led to an increase in socioeconomic inequality between women screened. Special attention must be paid to changes in socioeconomic and geographic inequality in the uptake of UCC screening when the programme is rolled out nationally.

Challenges of using nationally representative, population-based surveys to assess rural cancer disparities

Population-based surveys provide important information about cancer-related health behaviors across the cancer care continuum, from prevention to survivorship, to inform cancer control efforts. These surveys can illuminate cancer disparities among specific populations, including rural communities. However, due to small rural sample sizes, varying sampling methods, and/or other study design or analytical concerns, there are challenges in using population-based surveys for rural cancer control research and practice. Our objective is three-fold. First, we examined the characterization of "rural" in four, population-based surveys commonly referenced in the literature: 1) Health Information National Trends Survey (HINTS); 2) National Health Interview Survey (NHIS); 3) Behavioral Risk Factor Surveillance System (BRFSS); and 4) Medical Expenditures Panel Survey (MEPS). Second, we identified and described the challenges of using these surveys in rural cancer studies. Third, we proposed solutions to address these challenges. We found that these surveys varied in use of rural-urban classifications, sampling methodology, and available cancer-related variables. Further, we found that accessibility of these data to non-federal researchers has changed over time. Survey data have become restricted based on small numbers (i.e., BRFSS) and have made rural-urban measures only available for analysis at Research Data Centers (i.e., NHIS and MEPS). Additionally, studies that used these surveys reported varying proportions of rural participants with noted limitations in sufficient representation of rural minorities and/or cancer survivors. In order to mitigate these challenges, we propose two solutions: 1) make rural-urban measures more accessible to non-federal researchers and 2) implement sampling approaches to oversample rural populations.

Factors Determining Patients' Choice Between Mobile Health and Telemedicine: Predictive Analytics Assessment

BACKGROUND

The solution to the growing problem of rural residents lacking health care access may be found in the use of telemedicine and mobile health (mHealth). Using mHealth or telemedicine allows patients from rural or remote areas to have better access to health care.

OBJECTIVE

The objective of this study was to understand factors influencing the choice of communication medium for receiving care, through the analysis of mHealth versus telemedicine encounters with a virtual urgent clinic.

METHODS

We conducted a postdeployment evaluation of a new virtual health care service, Virtual Urgent Clinic, which uses mHealth and telemedicine modalities to provide patient care. We used a multinomial logistic model to test the significance and predictive power of a set of features in determining patients' preferred method of telecare encounters-a nominal outcome variable of two levels (mHealth and telemedicine).

RESULTS

Postdeployment, 1403 encounters were recorded, of which 1228 (87.53%) were completed with mHealth and 175 (12.47%) were telemedicine encounters. Patients' sex (P=.004) and setting (P<.001) were the most predictive determinants of their preferred method of telecare delivery, with significantly small P values of less than .01. Pearson chi-square test returned a strong indication of dependency between chief concern and encounter mediums, with an extremely small P<.001. Of the 169 mHealth patients who responded to the survey, 154 (91.1%) were satisfied by their encounter, compared with 31 of 35 (89%) telemedicine patients.

CONCLUSIONS

We studied factors influencing patients' choice of communication medium, either mHealth or telemedicine, for a virtual care clinic. Sex and geographic location, as well as their chief concern, were strong predictors of patients' choice of communication medium for their urgent care needs. This study suggests providing the option of mHealth or telemedicine to patients, and suggesting which medium would be a better fit for the patient based on their characteristics.

A Rural-Urban Comparison of Knowledge, Risk- Factors and Preventive Practices for Colorectal Cancer among Adults in Lagos State

Objective:

To assess and compare the knowledge, risk-factors and preventive practices for colorectal cancer among adults in Lagos State.

Material and methods:

This was a cross-sectional comparative study conducted among 607 respondents selected from one rural (Ikorodu) and one urban (Surulere) LGA using a multistage sampling technique. Data were collected using a pre-tested questionnaire administered by trained research assistants between April and September 2017.Data was analyzed using Epi-info statistical software version 3.5.1. Univariate and bivariate analysis was carried out and -p values of ≤0.05 were considered statistically significant.

Results:

Respondents’ knowledge of colorectal cancer was generally low, (rural-78.2%, urban- 62.2%, p<0.001). Urban respondents were significantly more knowledgeable than their rural counterparts (rural- 21.8%, urban- 37.8%, p<0.001). The presence of CRC risk-factors were higher among urban respondents (urban-49.3%, rural-42.6%, p= 0.09), however this difference was not statistically significant. Preventive practices were generally poor in both groups, although more (18.1%) urban respondents significantly took preventive actions against CRC compared with rural (6.9%) respondents, (p<0.001).Increasing levels of education were significantly associated with higher knowledge level in both groups (p≤0.05).

Conclusion:

The level of knowledge of colorectal cancer was generally poor in both groups but significantly poorer among rural respondents. The presence of known risk- factor was higher among urban respondents while preventive practices were poor in both groups.

Colorectal cancer screening: Understanding the health literacy needs of hispanic rural residents

Purpose

Hispanics residing in rural areas are among those who are least likely to be screened for colorectal cancer (CRC) and more likely to present with late stage CRC than other racial or ethnic groups. We conducted a pilot study utilizing a mixed-method approach to explore perceptions of CRC and CRC screening among Hispanic adults residing in South Texas rural communities and to identify health literacy needs associated with CRC screening uptake.

Methods

A convenience sample of 58 participants, aged 35–65, were recruited to complete questionnaires and participate in focus groups, ranging in size from 4 to 13 participants. Six focus groups were conducted across 3 adjacent rural counties. A semi-structured moderator's guide was designed to elicit discussion about participants' experiences, knowledge, and perceptions of CRC and CRC screening.

Findings

Lack of knowledge of CRC and CRC screening as cancer prevention was a common theme across focus groups. A majority, 59%, reported never been screened. Thirty-nine percent reported they had been screened for colon cancer and 5% reported they did not know if they had been screened. Participants with lower educational levels perceived themselves at high risk for developing CRC polyps, would not want to know if they had CRC, and if they did have CRC, would not want to know until the very end. Limited information about CRC and CRC screening, a lack of specialized providers, limited transportation assistance, and compromised personal privacy in small-town medical facilities were perceived to be barriers to CRC screening.

Conclusions

Low screening rates persist among rural Hispanics. Improving CRC screening literacy and addressing factors unique to rural Hispanics may be a beneficial strategy for reducing screening disparities in this at-risk population.

The impact of travel time on colorectal cancer stage at diagnosis in a privately insured population

BACKGROUND

Rural residents are less likely to receive screening for colorectal cancer (CRC) than urban residents. However, the mechanisms underlying this disparity, especially among people aged 50-64 years old with private health insurance, are not well understood. We examined the impact of travel time on stage at CRC diagnosis.

METHODS

This retrospective cohort study used data from the Blue Cross and Blue Shield of Nebraska. Members of this private insurance company aged 50-64 years, diagnosed with CRC during the period 2012-2016, and continuously enrolled in the insurance plan for at least 6 months prior to CRC diagnosis, were selected for this study. Using Google Maps, we estimated patients' travel time from their home ZIP code to the ZIP code of their colonoscopy provider. Using logistic regression, we analyzed the association between stage at CRC diagnosis, travel time, use of preventive services (i.e., check-ups or counseling to prevent or detect illness at an early stage) and patient characteristics.

RESULTS

A total of 307 subjects met the inclusion criteria. People who had not used preventive services 6 months prior to CRC diagnosis had 2.80 (95% CI, 1.00-7.90) times the odds of metastatic CRC compared to those who had used these services. No statistically significant association was found between travel time and metastatic CRC diagnosis (P = 0.99; 95% CI, 0.98-1.01).

CONCLUSIONS

The fact that 13% of the study population presented with metastatic CRC suggests some noncompliance with preventive services such as screening guidelines. To increase screening uptake and reduce metastatic cases, employers should offer incentives for their employees to make use of preventive services such as CRC screening.

Should Measures of Health Care Availability Be Based on the Providers or the Procedures? A Case Study with Implications for Rural Colorectal Cancer Disparities

PURPOSE

Patients with colorectal cancer (CRC) living in rural areas have lower survival rates than those in urban areas, potentially because of lack of access to quality CRC screening and treatment. The purpose of this study was to compare traditional physician density (ie, colonoscopy provider availability per capita) against a new physician density measure using an example case of colonoscopy volume and quality. The latter is particularly relevant for rural providers, who may have fewer patients and are more frequently nongastroenterologists.

METHODS

We conducted a secondary data analysis of the 2014 Medicare Provider Utilization and Payment Database and the National Cancer Institute State Cancer Profile Database. Volume-weighted physician density scores at the state and county levels were created, accounting for (1) the physician's annual colonoscopy volume and (2) whether the physician performs ≥100 procedures per year. We compared volume-weighted versus traditional density, overall and by rurality, and examined their correlation with CRC screening, incidence, and mortality rates.

FINDINGS

The difference between volume-weighted and traditional density scores was particularly large in rural parts of the West and Midwest, and it was most similar in the Northeast. Although weak, correlations with CRC outcomes were stronger for volume-weighted density, and they did not differ by rurality.

CONCLUSIONS

Our new method is an improvement over traditional methods because it considers the variation of physician procedure volume, and it has a stronger correlation with population health outcomes. Weighted density scores portray a more realistic picture of physician supply, particularly in rural areas.

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

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

Rural-Urban Disparities in Stage of Diagnosis Among Cancers With Preventive Opportunities

INTRODUCTION

Despite having lower overall incidence rates, rural populations tend to have higher cancer mortality rates. Rural populations often have higher rates of cancers with primary and secondary prevention modalities. However, there is limited research on rural-urban differences in incidence by stage. Therefore, the objective was to assess rural-urban differences in cancer rates by stage.

METHODS

The North American Association of Central Cancer Registries public use data set (2009-2013) was used to calculate age-adjusted incidence rates and rate ratios (rural versus urban) for all stageable cancers, tobacco-associated cancers, human papillomavirus-associated cancers, and individual cancers with screening modalities. Analyses were performed in summer 2017 for all populations and stratified by race/ethnicity and region for localized and distant stages.

RESULTS

For all cancers, rural populations had lower rates of localized stage cancers (rate ratio=0.95, 95% CI=0.95, 0.95) and higher rates of distant stage cancer (rate ratio=1.05, 95% CI=1.05, 1.06). Higher rates of distant stage human papillomavirus-associated, tobacco-associated, colorectal, oropharyngeal, lung, cervical cancers, and melanoma were identified in rural populations. Racial/ethnic stratifications identified higher rates of distant stage cancers in rural non-Hispanic whites, but not non-Hispanic blacks and Hispanics. Distant stage lung cancer rates were higher in all rural groups, whereas rural whites had higher distant rates of tobacco-associated, colorectal, and cervical cancers, and rural blacks had higher distant rates for human papillomavirus-associated and oral cancers. Regional stratifications showed the greatest disparity in stage at diagnosis in the South.

CONCLUSIONS

These findings might help explain the higher rural cancer mortality rates and provide additional evidence to support targeted interventions.

Histologic Lung Cancer Incidence Rates and Trends Vary by Race/Ethnicity and Residential County

INTRODUCTION

Lung cancer incidence is higher among non-Hispanic (NH) blacks than among the NH white and Hispanic populations in the United States. However, national cancer estimates may not always reflect the cancer burden in terms of disparities and incidence in small geographic areas, especially urban-rural disparities. Moreover, there is a gap in the literature regarding rural-urban disparities in terms of cancer histologic type.

METHODS

Using population-based cancer registry data-Surveillance, Epidemiology and End Results and National Program of Cancer Registries data-we present age-adjusted histologic rates and trends by race/ethnicity and residential county location at the time of first cancer diagnosis. Rate ratios were calculated to examine racial/ethnic differences in rates. Annual percent change was calculated to measure changes in rates over time.

RESULTS

We found that declines in squamous cell carcinoma are occurring fastest in metropolitan counties, whereas rates of adenocarcinoma increased fastest in counties nonadjacent to metropolitan areas. Further, although NH black men have increased lung cancer incidence compared with NH white and Hispanic men in all geographic locations, we found that the degree of the disparity increases with increasing rurality of residence. Finally, we discovered that among women whose lung cancer was diagnosed when they were younger than 55 years, the incidence of squamous cell carcinoma and adenocarcinoma was higher for NH blacks than for NH whites.

CONCLUSIONS

Our results highlight disparities among NH blacks in nonadjacent rural areas. These findings may have significant impact for the implementation of smoking cessation and lung cancer screening programs.

Racial/Ethnic Health Disparities Among Rural Adults - United States, 2012-2015

PROBLEM/CONDITION

Rural communities often have worse health outcomes, have less access to care, and are less diverse than urban communities. Much of the research on rural health disparities examines disparities between rural and urban communities, with fewer studies on disparities within rural communities. This report provides an overview of racial/ethnic health disparities for selected indicators in rural areas of the United States.

REPORTING PERIOD

2012-2015.

DESCRIPTION OF SYSTEM

Self-reported data from the 2012-2015 Behavioral Risk Factor Surveillance System were pooled to evaluate racial/ethnic disparities in health, access to care, and health-related behaviors among rural residents in all 50 states and the District of Columbia. Using the National Center for Health Statistics 2013 Urban-Rural Classification Scheme for Counties to assess rurality, this analysis focused on adults living in noncore (rural) counties.

RESULTS

Racial/ethnic minorities who lived in rural areas were younger (more often in the youngest age group) than non-Hispanic whites. Except for Asians and Native Hawaiians and other Pacific Islanders (combined in the analysis), more racial/ethnic minorities (compared with non-Hispanic whites) reported their health as fair or poor, that they had obesity, and that they were unable to see a physician in the past 12 months because of cost. All racial/ethnic minority populations were less likely than non-Hispanic whites to report having a personal health care provider. Non-Hispanic whites had the highest estimated prevalence of binge drinking in the past 30 days.

INTERPRETATION

Although persons in rural communities often have worse health outcomes and less access to health care than those in urban communities, rural racial/ethnic minority populations have substantial health, access to care, and lifestyle challenges that can be overlooked when considering aggregated population data. This study revealed difficulties among non-Hispanic whites as well, primarily related to health-related risk behaviors. Across each population, the challenges vary.

PUBLIC HEALTH ACTION

Stratifying data by different demographics, using community health needs assessments, and adopting and implementing the National Culturally and Linguistically Appropriate Services Standards can help rural communities identify disparities and develop effective initiatives to eliminate them, which aligns with a Healthy People 2020 overarching goal: achieving health equity.

Barriers and Facilitators to Colorectal Cancer Screening Among Rural Women in Community Clinics by Heath Literacy

BACKGROUND

Rural women lag rural men and urban women in colon cancer (CRC) screening completion.

OBJECTIVE

To identify rural female patients' knowledge, beliefs barriers, self-efficacy, prior recommendation and completion of CRC screening using an FOBT and to compare these factors by health literacy (HL) level.

METHODS

This descriptive study was conducted between 2015 and 2016 in 4 rural community clinics in south Louisiana. Patients overdue for screening were given a structured interview by a research assistant.

RESULTS

339 women were enrolled, mean age 58.5, 32% had limited HL, 66% were African American. Most (91.7%) had heard of CRC, yet only 71% knew of any CRC screening tests. Women with adequate HL had greater knowledge of specific tests than those with limited HL (78.4% vs 56.6%, p<0.001). Only 25.7% had been given information on CRC testing; those with adequate HL were more likely to have received information (30.1% vs 16.8%; p=0.017). Most women (93.2%) indicated they would want to know if they had CRC, while 72.2% reported a provider had recommended CRC screening. Only 24.9% said a healthcare provider had ever given them an FOBT or that they had ever completed an FOBT (22.7%). There were no differences in women's report of recommendation or completion by HL level.Self-efficacy for completing an FOBT was high; over 90% indicated they could get an FOBT, complete it and mail results to the lab. Level of confidence did not vary by literacy. Three of the four barrier items varied by HL with women with low HL being more likely to fear doing an FOBT because they thought FOBT instructions would be confusing (p=0.002), doing the test would be embarrassing (p=0.025) or messy (p=0.057).

CONCLUSIONS

Rural women are receptive to CRC screening and view FOBTs as effective. Rural community clinics need to provide low cost FOBTs with literacy, gender and culturally appropriate information.

Rural-Urban Differences in Cancer Incidence and Trends in the United States

Background: Cancer incidence and mortality rates in the United States are declining, but this decrease may not be observed in rural areas where residents are more likely to live in poverty, smoke, and forego cancer screening. However, there is limited research exploring national rural-urban differences in cancer incidence and trends.Methods: We analyzed data from the North American Association of Central Cancer Registries' public use dataset, which includes population-based cancer incidence data from 46 states. We calculated age-adjusted incidence rates, rate ratios, and annual percentage change (APC) for: all cancers combined, selected individual cancers, and cancers associated with tobacco use and human papillomavirus (HPV). Rural-urban comparisons were made by demographic, geographic, and socioeconomic characteristics for 2009 to 2013. Trends were analyzed for 1995 to 2013.Results: Combined cancers incidence rates were generally higher in urban populations, except for the South, although the urban decline in incidence rate was greater than in rural populations (10.2% vs. 4.8%, respectively). Rural cancer disparities included higher rates of tobacco-associated, HPV-associated, lung and bronchus, cervical, and colorectal cancers across most population groups. Furthermore, HPV-associated cancer incidence rates increased in rural areas (APC = 0.724, P < 0.05), while temporal trends remained stable in urban areas.Conclusions: Cancer rates associated with modifiable risks-tobacco, HPV, and some preventive screening modalities (e.g., colorectal and cervical cancers)-were higher in rural compared with urban populations.Impact: Population-based, clinical, and/or policy strategies and interventions that address these modifiable risk factors could help reduce cancer disparities experienced in rural populations.

Making the Case for Investment in Rural Cancer Control: An Analysis of Rural Cancer Incidence, Mortality, and Funding Trends

Estimates of those living in rural counties vary from 46.2 to 59 million, or 14% to 19% of the U.S.

POPULATION

Rural communities face disadvantages compared with urban areas, including higher poverty, lower educational attainment, and lack of access to health services. We aimed to demonstrate rural-urban disparities in cancer and to examine NCI-funded cancer control grants focused on rural populations. Estimates of 5-year cancer incidence and mortality from 2009 to 2013 were generated for counties at each level of the rural-urban continuum and for metropolitan versus nonmetropolitan counties, for all cancers combined and several individual cancer types. We also examined the number and foci of rural cancer control grants funded by NCI from 2011 to 2016. Cancer incidence was 447 cases per 100,000 in metropolitan counties and 460 per 100,000 in nonmetropolitan counties (P < 0.001). Cancer mortality rates were 166 per 100,000 in metropolitan counties and 182 per 100,000 in nonmetropolitan counties (P < 0.001). Higher incidence and mortality in rural areas were observed for cervical, colorectal, kidney, lung, melanoma, and oropharyngeal cancers. There were 48 R- and 3 P-mechanism rural-focused grants funded from 2011 to 2016 (3% of 1,655). Further investment is needed to disentangle the effects of individual-level SES and area-level factors to understand observed effects of rurality on cancer.

Racial and ethnic residential segregation and access to health care in rural areas

This study examined the relationship between racial/ethnic residential segregation and access to health care in rural areas. Data from the Medical Expenditure Panel Survey were merged with the American Community Survey and the Area Health Resources Files. Segregation was operationalized using the isolation index separately for African Americans and Hispanics. Multi-level logistic regression with random intercepts estimated four outcomes. In rural areas, segregation contributed to worse access to a usual source of health care but higher reports of health care needs being met among African Americans (Adjusted Odds Ratio [AOR]: 1.42, CI: 0.96-2.10) and Hispanics (AOR: 1.25, CI: 1.05-1.49). By broadening the spatial scale of segregation beyond urban areas, findings showed the complex interaction between social and spatial factors in rural areas.

Rural-Urban Differences in Colorectal Cancer Screening Barriers in Nebraska

Nebraska ranks 36th nationally in colorectal cancer screening. Despite recent increases in CRC screening rates, rural areas in Nebraska have consistently shown lower rates of CRC screening uptake, compared to urban areas. The objective of this study was to investigate reasons for lower CRC screening rates among Nebraska residents, especially among rural residents. We developed a questionnaire based on Health Belief Model (HBM) constructs to identify factors associated with the use of CRC screening. The questionnaire was mailed in 2014 to adults aged 50-75 years in an urban community in the east and a rural community in the west regions of the state. Multiple logistic regression models were created to assess the effects of HBM constructs, rural residence, and demographic factors on CRC screening use. Of the 1200 surveys mailed, 393 were returned (rural n = 200, urban n = 193). Rural respondents were more likely to perceive screening cost as a barrier. Rural residents were also more likely to report that CRC cannot be prevented and it would change their whole life. In multiple regression models, rural residence, perceived embarrassment, and perceived unpleasantness about screening were significantly associated with reduced odds of receiving colonoscopy. Older age (62 years and older), having a personal doctor, and perceived risk of getting CRC were significantly associated with increased odds of receiving colonoscopy. Interventions to increase uptake of colorectal cancer screening in rural residents should be tailored to acknowledge unique perceptions of screening methods and barriers to screening.

Intersection of Living in a Rural Versus Urban Area and Race/Ethnicity in Explaining Access to Health Care in the United States

OBJECTIVES

To examine whether living in a rural versus urban area differentially exposes populations to social conditions associated with disparities in access to health care.

METHODS

We linked Medical Expenditure Panel Survey (2005-2010) data to geographic data from the American Community Survey (2005-2009) and Area Health Resource File (2010). We categorized census tracts as rural and urban by using the Rural-Urban Commuting Area Codes. Respondent sample sizes ranged from 49 839 to 105 306. Outcomes were access to a usual source of health care, cholesterol screening, cervical screening, dental visit within recommended intervals, and health care needs met.

RESULTS

African Americans in rural areas had lower odds of cholesterol screening (odds ratio[OR] = 0.37; 95% confidence interval[CI] = 0.25, 0.57) and cervical screening (OR = 0.48; 95% CI = 0.29, 0.80) than African Americans in urban areas. Whites had fewer screenings and dental visits in rural versus urban areas. There were mixed results for which racial/ethnic group had better access.

CONCLUSIONS

Rural status confers additional disadvantage for most of the health care use measures, independently of poverty and health care supply.

Racial and Ethnic Disparities in the Quality of Health Care

The annual National Healthcare Quality and Disparities Reports document widespread and persistent racial and ethnic disparities. These disparities result from complex interactions between patient factors related to social disadvantage, clinicians, and organizational and health care system factors. Separate and unequal systems of health care between states, between health care systems, and between clinicians constrain the resources that are available to meet the needs of disadvantaged groups, contribute to unequal outcomes, and reinforce implicit bias. Recent data suggest slow progress in many areas but have documented a few notable successes in eliminating these disparities. To eliminate these disparities, continued progress will require a collective national will to ensure health care equity through expanded health insurance coverage, support for primary care, and public accountability based on progress toward defined, time-limited objectives using evidence-based, sufficiently resourced, multilevel quality improvement strategies that engage patients, clinicians, health care organizations, and communities.

Determinants of variations in self-reported barriers to colonoscopy among uninsured patients in a primary care setting

Colorectal cancer (CRC) is the third most common type of cancer among both males and females in the United States and the second leading cause of cancer-related deaths. Although largely preventable through screening, early detection and removal of polyps, screening rates are considered sub-optimal. Perceived barriers to screening have been reported to influence screening rates. This paper examines variations in the extent to which uninsured patients identified barriers to CRC screening using colonoscopy based on race/ethnicity, educational attainment, age, gender, marital status and prior colonoscopy. Multivariate analyses showed that compared to Caucasians, African Americans had an increased likelihood of identifying lack of transportation as a barrier [odds ratio (OR) 2.68; 95 % confidence interval (CI) 1.35-5.32] while Hispanics were more likely to identify fear of finding cancer as a barrier (OR 2.09; 95 % CI 1.19-3.66). Compared to those with more than a high school education, there was increased likelihood of identifying lack of knowledge as a barrier among individuals with high school education (OR 3.51; 95 % CI 1.94-6.36) or less than a high school education (OR 2.16; 95 % CI 1.04-4.50). Our findings suggest that strategies aimed at increasing colonoscopy screening rates among underserved populations should take into consideration race/ethnicity, educational attainment, age, and prior colonoscopy experience when developing education and outreach plans to reduce barriers to colonoscopy.

Is Travel Time to Colonoscopy Associated With Late-Stage Colorectal Cancer Among Medicare Beneficiaries in Iowa?

BACKGROUND

Colorectal cancer (CRC) screening has been shown to decrease the incidence of late-stage colorectal cancer, yet a substantial proportion of Americans do not receive screening. Those in rural areas may face barriers to colonoscopy services based on travel time, and previous studies have demonstrated lower screening among rural residents. Our purpose was to assess factors associated with late-stage CRC, and specifically to determine if longer travel time to colonoscopy was associated with late-stage CRC among an insured population in Iowa.

METHODS

SEER-Medicare data were used to identify individuals ages 65 to 84 years old diagnosed with CRC in Iowa from 2002 to 2009. The distance between the centroid of the ZIP code of residence and the ZIP code of colonoscopy was computed for each individual who had continuous Medicare fee-for-service coverage for a 3- to 4-month period prior to diagnosis, and a professional claim for colonoscopy within that time frame. Demographic characteristics and travel times were compared between those diagnosed with early- versus late-stage CRC. Also, demographic differences between those who had colonoscopy claims identified within 3-4 months prior to diagnosis (81%) were compared to patients with no colonoscopy claims identified (19%).

RESULTS

A total of 5,792 subjects met inclusion criteria; 31% were diagnosed with early-stage versus 69% with late-stage CRC. Those divorced or widowed (vs married) were more likely to be diagnosed with late-stage CRC (OR: 1.20, 95% CI: 1.06-1.37). Travel time was not associated with diagnosis of late-stage CRC.

DISCUSSION

Among a Medicare-insured population, there was no relationship between travel time to colonoscopy and disease stage at diagnosis. It is likely that factors other than distance to colonoscopy present more pertinent barriers to screening in this insured population. Additional research should be done to determine reasons for nonadherence to screening among those with access to CRC screening services, given that over two-thirds of these insured individuals were diagnosed with late-stage CRC.

The Urban/Rural Dichotomy in the Distribution of Breast Cancer across Pennsylvania

Breast cancer rates clearly differ across the United States. This is due to a variety of factors, but at least one determinant is the population density. Breast cancer detection rates and treatment paradigms may differ in rural areas when compared with more urban ones. As the population becomes more mobile and diffuse, this may or may not be a worsening problem. The current analysis was undertaken to examine the breast cancer incidence and outcomes in a single state in an attempt to plan for resource allocation in the future. A retrospective analysis was performed using data available from the Pennsylvania Department of Health regarding breast cancer rates by county, the distribution of cases with regard to degree of rurality, death rates by county as a function of rurality, and the age distribution of all presenting cases. Data from 1999 were compared with those of 2009. The United States Census Bureau definition of rurality was used, which specifies that a county be classified as rural if the population density is less than 284 persons/square mile. Between 1999 and 2009, the population of Pennsylvania increased by approximately 3.4 per cent (421,325 people). The urban population increased by 3.9 per cent, whereas the rural population increased by only 2.2 per cent. During that same period, the number of cancer cases/100,000 population remained about the same: 391.41 in 1999; 390.7 in 2009. However, the distribution of cases shifted during that time toward more rural areas of the state: in 1999, there were 372.3 breast cancer cases/100,000 population compared with 2009 when the rate was 384.4/100,000 population. The number of cancer deaths/100,000 population actually dropped overall during the decade: 98.5 in 1999 versus 82.3 in 2009. Though this was true in both urban and rural counties, the decrease was much less pronounced in the rural areas. In urban counties, the death rate dropped from 100.5 to 81.5/100,000 population, whereas in rural counties, the drop was only from 93.3 to 84.3. The greater increase in cases diagnosed in rural areas of Pennsylvania is only partially explained by the relatively greater increase in rural population. There are undoubtedly other issues at work in rural areas: environmental factors, diffusion of resources, less access to surveillance programs. In addition, though the death rate has dropped in both rural and urban areas, this is much less pronounced in rural counties. Coupled with the increase in prevalence in those areas, this suggests that breast cancer care may be lagging in rural areas. There is a need to examine allocation of resources and surveillance programs.

Race/ethnicity and the socioeconomic status gradient in women's cancer screening utilization: a case of diminishing returns?

Using three years (2006, 2008, 2010) of nationally representative data from the Behavioral Risk Factor Surveillance System, I assessed the socioeconomic status (SES) gradient for odds of receiving a mammogram in the past two years and a Pap test in the past three years among White, Black, Hispanic, and Asian women living in the U.S. Mammogram and Pap test utilization were less likely among low-SES women. However, women of color experience less benefit than Whites from increasing SES for both screenings; as income and education increased, White women experienced more pronounced increases in the likelihood of being screened than did women of color. In what might be referred to as paradoxical returns, Asian women actually experienced a decline in the likelihood of obtaining a recent Pap test at higher levels of education. My findings suggest that women of color differ from Whites in the extent to which increasing socioeconomic resources is associated with increasing cancer screening utilization.

Predictors of Colorectal Cancer Screening: Does Rurality Play a Role?

PURPOSE

The purpose of this study was to explore the associations between sociodemographic factors such as residence, health care access, and colorectal cancer (CRC) screening among residents of Texas.

METHODS

Using the 2012 Behavioral Risk Factor Surveillance Survey, we performed logistic regression analyses to determine predictors of CRC screening among Texas residents, including rural versus urban differences. Our outcomes of interest were previous (1) CRC screening using any CRC test, (2) fecal occult blood test (FOBT), or (3) endoscopy, as well as up-to-date screening using (4) any CRC test, (5) FOBT, or (6) endoscopy. The independent variable of interest was rural versus urban residence; we controlled for other sociodemographic and health care access variables such as lack of health insurance.

RESULTS

Multivariate analysis showed that individuals who were residents of a rural/non-Metropolitan Statistical Area (MSA) location (OR = 0.70, 95% CI = 0.51-0.97) or a suburban county (OR = 0.61, 95% CI = 0.39-0.95) were less likely to report ever having any CRC screening compared to residents of a center city of an MSA. Residents of a rural/non-MSA location were less likely (OR = 0.49, 95% CI = 0.28-0.87) than residents of a center city of an MSA to be up-to-date using FOBT. There was decreased likelihood of ever being screened for CRC among the uninsured (OR = 0.43, 95% CI = 0.31-0.59).

CONCLUSIONS

Effective development and implementation of strategies to improve screening rates should aim at improving access to health care, taking into account demographic characteristics such as rural versus urban residence.

Predictors of never being screened for cervical cancer by metropolitan area

Previous studies have shown an association between cervical cancer screening and racial/ethnic minority status, no usual source of care, and lower socioeconomic status. This study describes the demographics and health beliefs of women who report never being screened for cervical cancer by area of residence. Data from the 2010 Behavioral Risk Factor Surveillance System were used to study women aged 21-65 years who reported never being screened for cervical cancer. Multivariate logistic regression modeling was used to calculate predicted marginals to examine associations between never being screened and demographic characteristics and health belief model (HBM) constructs by metropolitan statistical area (MSA). After adjusting for all demographics and HBM constructs, prevalence of never being screened was higher for the following women: non-Hispanic Asians/Native Hawaiians/Pacific Islanders (16.5 %, 95 % CI = 13.7 %, 19.8 %) who live in MSAs; those with only a high school diploma who live in MSAs (5.5 %, 95 % CI = 4.7 %, 6.5 %); those living in non-MSAs who reported "fair or poor" general health (4.1 %, 95 % CI = 3.1 %, 5.4 %); and those living in either MSAs and non-MSAs unable to see a doctor within the past 12 months because of cost (MSA: 4.4 %, 95 % CI = 4.0 %, 4.8 %; non-MSA: 3.4 %, 95 % CI = 2.9 %, 3.9 %). The Affordable Care Act will expand access to insurance coverage for cervical cancer screening, without cost sharing for millions of women, essentially eliminating insurance costs as a barrier. Future interventions for women who have never been screened should focus on promoting the importance of screening and reaching non-Hispanic Asians/Native Hawaiians/Pacific Islanders who live in MSAs.

Geographic access to breast imaging for US women

PURPOSE

The breast imaging modalities of mammography, ultrasound, and MRI are widely used for screening, diagnosis, treatment, and surveillance of breast cancer. Geographic access to breast imaging services in various modalities is not known at a national level overall or for population subgroups.

METHODS

A retrospective study of 2004-2008 Medicare claims data was conducted to identify ZIP codes in which breast imaging occurred, and data were mapped. Estimated travel times were made for each modality for 215,798 census block groups in the contiguous United States. Using Census 2010 data, travel times were characterized by sociodemographic factors for 92,788,909 women aged ≥30 years, overall, and by subgroups of age, race/ethnicity, rurality, education, and median income.

RESULTS

Overall, 85% of women had travel times of ≤20 minutes to nearest mammography or ultrasound services, and 70% had travel times of ≤20 minutes for MRI with little variation by age. Native American women had median travel times 2-3 times longer for all 3 modalities, compared to women of other racial/ethnic groups. For rural women, median travel times to breast imaging services were 4-8-fold longer than they were for urban women. Black and Asian women had the shortest median travel times to services for all 3 modalities.

CONCLUSIONS

Travel times to mammography and ultrasound breast imaging facilities are short for most women, but for breast MRI, travel times are notably longer. Native American and rural women are disadvantaged in geographic access based on travel times to breast imaging services. This work informs potential interventions to reduce inequities in access and utilization.

Impact of state-specific Medicaid reimbursement and eligibility policies on receipt of cancer screening

BACKGROUND

Although state Medicaid programs cover cancer screening, Medicaid beneficiaries are less likely to be screened for cancer and are more likely to present with tumors of an advanced stage than are those with other insurance. The current study was performed to determine whether state Medicaid eligibility and reimbursement policies affect the receipt of breast, cervical, and colon cancer screening among Medicaid beneficiaries.

METHODS

Cross-sectional regression analyses of 2007 Medicaid data from 46 states and the District of Columbia were performed to examine associations between state-specific Medicaid reimbursement/eligibility policies and receipt of cancer screening. The study sample included individuals aged 21 years to 64 years who were enrolled in fee-for-service Medicaid for at least 4 months. Subsamples eligible for each screening test were: Papanicolaou test among 2,136,511 patients, mammography among 792,470 patients, colonoscopy among 769,729 patients, and fecal occult blood test among 753,868 patients. State-specific Medicaid variables included median screening test reimbursement, income/financial asset eligibility requirements, physician copayments, and frequency of eligibility renewal.

RESULTS

Increases in screening test reimbursement demonstrated mixed associations (positive and negative) with the likelihood of receiving screening tests among Medicaid beneficiaries. In contrast, increased reimbursements for office visits were found to be positively associated with the odds of receiving all screening tests examined, including colonoscopy (odds ratio [OR], 1.07; 95% confidence interval [95% CI], 1.06-1.08), fecal occult blood test (OR, 1.09; 95% CI, 1.08-1.10), Papanicolaou test (OR, 1.02; 95% CI, 1.02-1.03), and mammography (OR, 1.02; 95% CI, 1.02-1.03). Effects of other state-specific Medicaid policies varied across the screening tests examined.

CONCLUSIONS

Increased reimbursement for office visits was consistently associated with an increased likelihood of being screened for cancer, and may be an important policy tool for increasing screening among this vulnerable population.

United States colorectal cancer screening practices among American Indians/Alaska Natives, blacks, and non-Hispanic whites in the new millennium (2001 to 2010)

BACKGROUND

The objectives of this study were to describe, examine, and compare prevalence estimates of colorectal cancer (CRC) screening practices and to determine whether disparities exist for American Indians/Alaska Natives (AIANs) and blacks compared with whites.

METHODS

Behavioral Risk Factor Surveillance System (2001-2010) data from respondents aged ≥ 50 years (n = 356,073) were used. The primary outcome was self-reported CRC screening according to US Preventive Services Task Force guidelines for endoscopy (colonoscopy or sigmoidoscopy), fecal occult blood test (FOBT), or mixed screening (endoscopy or FOBT).

RESULTS

From 2001 to 2010, endoscopy screening increased in the AIAN population by 44.8% (P < .001) compared with black respondents (51.7%) and white respondents (26.5%). AIANs were less likely to report endoscopy screening (45%) compared with both blacks (56%) and whites (55%). For mixed CRC screenings, AIAN rates increased by 34.5%, compared with 29.7% for blacks and 15% for whites. In 2010, AIANs (51%) had the lowest prevalence of mixed CRC screening compared with blacks (61%) and whites (60%; P < .001). Factors that enabled health care attenuated the lowered likelihood of CRC screenings, but disparities remained for AIAN CRC screening. In contrast, once enabling factors were controlled, the odds ratios of CRC screening among blacks were higher compared with whites.

CONCLUSIONS

Between 2001 and 2010, AIANs had the lowest CRC screening rates in the United States compared with blacks and whites, presenting a CRC disparity, as rigorously defined. The current findings indicate that, although considerable progress has been made to increase CRC screening for blacks and whites, progress for AIANs continues to lag behind in the first decade of 21st century.
