Disparities in Patient Portal Use Among Adults With Chronic Conditions.

Importance: Disparities in patient access and use of health care portals have been documented. Limited research has evaluated disparities in portal use during and after the COVID-19 pandemic. Objective: To assess prevalence of health care portal use before, during, and after the most restrictive phase of the pandemic (2019-2022) among the COVID-19 & Chronic Conditions (C3) cohort and to investigate any disparities in use by sociodemographic factors. Design, Setting, and Participants: This cohort study uses data from the C3 study, an ongoing, longitudinal, telephone-based survey of participants with multiple chronic conditions. Participants were middle aged and older-adult primary care patients who had an active portal account, recruited from a single academic medical center in Chicago, Illinois, between 2019 and 2022. Data were analyzed between March and June 2022. Main Outcomes and Measures: Outcomes of portal use (ie, number of days of portal login by year) were recorded for all study participants by the electronic data warehouse. All parent studies had uniform sociodemographic data and measures of social support, self-efficacy, health literacy, and health activation. Results: Of 536 participants (mean [SD] age, 66.7 [12.0] years; 336 [62.7%] female), 44 (8.2%) were Hispanic or Latinx, 142 (26.5%) were non-Hispanic Black, 322 (60.1%) were non-Hispanic White, and 20 individuals (3.7%) identified as other race, including Asian, Native American or Alaskan Native, and self-reported other race. In multivariable analyses, portal login activity was higher during the 3 years of the COVID-19 pandemic compared with the 2019 baseline. Higher portal login activity was associated with adequate health literacy (incidence rate ratio [IRR], 1.51; 95% CI, 1.18-1.94) and multimorbidity (IRR, 1.38; 95% CI, 1.17-1.64). Lower portal activity was associated with older age (≥70 years: IRR, 0.69; 95% CI, 0.55-0.85) and female sex (IRR, 0.77; 95% CI, 0.66-0.91). Compared with non-Hispanic White patients, lower portal activity was observed among Hispanic or Latinx patients (IRR, 0.66; 95% CI, 0.49-0.89), non-Hispanic Black patients (IRR, 0.68; 95% CI, 0.56-0.83), and patients who identified as other race (IRR, 0.42; 95% CI, 0.28-0.64). Conclusions and Relevance: This cohort study using data from the C3 study identified changes in portal use over time and highlighted populations that had lower access to health information. The COVID-19 pandemic was associated with an increase in portal use. Sociodemographic disparities by sex and age were reduced, although disparities by health literacy widened. A brief validated health literacy measure may serve as a useful digital literacy screening tool to identify patients who need further support.

Rural-urban differences in personality traits and well-being in adulthood.

OBJECTIVE: One large focus of personality psychology is to understand the biopsychosocial factors responsible for adult personality development and well-being change. However, little is known about how macro-level contextual factors, such as rurality-urbanicity, are related to personality development and well-being change. METHOD: The present study uses data from two large longitudinal studies of U.S. Americans (MIDUS, HRS) to examine whether there are rural-urban differences in levels and changes in the Big Five personality traits and well-being (i.e., psychological well-being, and life satisfaction) in adulthood. RESULTS: Multilevel models showed that Americans who lived in more rural areas tended to have lower levels of openness, conscientiousness, and psychological well-being, and higher levels of neuroticism. With the exception of psychological well-being (which replicated across MIDUS and HRS), rural-urban differences in personality traits were only evident in the HRS sample. The effect of neuroticism was fully robust to the inclusion of socio-demographic and social network covariates, but other effects were partially robust (i.e., conscientiousness and openness) or were not robust at all (i.e., psychological well-being). In both samples, there were no rural-urban differences in Big Five or well-being change. CONCLUSIONS: We discuss the implications of these findings for personality and rural health research.

The impact of marital status on tumor aggressiveness, treatment, and screening among black and white men diagnosed with prostate cancer.

PURPOSE: To examine the association of marital status with prostate cancer outcomes in a racially-diverse cohort. METHODS: The study population consisted of men (1010 Black; 1070 White) with incident prostate cancer from the baseline North Carolina-Louisiana Prostate Cancer (PCaP) cohort. Marital status at time of diagnosis and screening history were determined by self-report. The binary measure of marital status was defined as married (including living as married) vs. not married (never married, divorced/separated, or widowed). High-aggressive tumors were defined using a composite measure of PSA, Gleason Score, and stage. Definitive treatment was defined as receipt of radical prostatectomy or radiation. Multivariable logistic regression was used to examine the association of marital status with (1) high-aggressive tumors, (2) receipt of definitive treatment, and (3) screening history among Black and White men with prostate cancer. RESULTS: Black men were less likely to be married than White men (68.1% vs. 83.6%). Not being married (vs. married) was associated with increased odds of high-aggressive tumors in the overall study population (adjusted Odds Ratio (aOR): 1.56; 95% Confidence Interval (CI): 1.20-2.02) and both Black and White men in race-stratified analyses. Unmarried men were less likely to receive definitive treatment in the overall study population (aOR: 0.68; 95% CI: 0.54-0.85). In race-stratified analyses, unmarried Black men were less likely to receive definitive treatment. Both unmarried Black and White men were less likely to have a history of prostate cancer screening than married men. CONCLUSION: Lower rates of marriage among Black men might signal decreased support for treatment decision-making, symptom management, and caregiver support which could potentially contribute to prostate cancer disparities.

Opportunities, challenges, and future directions for simulation modeling the effects of structural racism on cancer mortality in the United States: a scoping review.

PURPOSE: Structural racism could contribute to racial and ethnic disparities in cancer mortality via its broad effects on housing, economic opportunities, and health care. However, there has been limited focus on incorporating structural racism into simulation models designed to identify practice and policy strategies to support health equity. We reviewed studies evaluating structural racism and cancer mortality disparities to highlight opportunities, challenges, and future directions to capture this broad concept in simulation modeling research. METHODS: We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Scoping Review Extension guidelines. Articles published between 2018 and 2023 were searched including terms related to race, ethnicity, cancer-specific and all-cause mortality, and structural racism. We included studies evaluating the effects of structural racism on racial and ethnic disparities in cancer mortality in the United States. RESULTS: A total of 8345 articles were identified, and 183 articles were included. Studies used different measures, data sources, and methods. For example, in 20 studies, racial residential segregation, one component of structural racism, was measured by indices of dissimilarity, concentration at the extremes, redlining, or isolation. Data sources included cancer registries, claims, or institutional data linked to area-level metrics from the US census or historical mortgage data. Segregation was associated with worse survival. Nine studies were location specific, and the segregation measures were developed for Black, Hispanic, and White residents. CONCLUSIONS: A range of measures and data sources are available to capture the effects of structural racism. We provide a set of recommendations for best practices for modelers to consider when incorporating the effects of structural racism into simulation models.

The Role of BMI in Allostatic Load and Risk of Cancer Death.

INTRODUCTION: Obesity and proinflammatory conditions are associated with increased risks of cancer. The associations of baseline allostatic load with cancer mortality and whether this association is modified by body mass index (BMI) were examined. METHODS: A retrospective analysis was performed in March-September 2022 using National Health and Nutrition Examination Survey years 1988 through 2010 linked with the National Death Index through December 31, 2019. Fine and Gray Cox proportional hazard models were stratified by BMI status to estimate subdistribution hazard ratios of cancer death between high and low allostatic load status (adjusted for age, sociodemographics, and health factors). RESULTS: In fully adjusted models, high allostatic load was associated with a 23% increased risk of cancer death (adjusted subdistribution hazard ratio=1.23; 95% CI=1.06, 1.43) among all participants, a 3% increased risk of cancer death (adjusted subdistribution hazard ratio=1.03; 95% CI=0.78, 1.34) among underweight/healthy weight adults, a 31% increased risk of cancer death (adjusted subdistribution hazard ratio=1.31; 95% CI=1.02, 1.67) among overweight adults, and a 39% increased risk of death (adjusted subdistribution hazard ratio=1.39; 95% CI=1.04, 1.88) among obese adults, when compared to those with low allostatic load. CONCLUSIONS: The risk of cancer death is highest among those with high allostatic load and obese BMI, but this effect was attenuated among those with high allostatic load and underweight/healthy or overweight BMI.

Adapting a Research and Community Capacity-Building Program to Address Rural Cancer Burden and Facilitate Partnership Development Between Rural Community Stakeholders and an Urban Comprehensive Cancer Center.

While rural-urban cancer disparities persist, the research building capacity between rural communities and high-quality cancer centers remains limited. Thus, we describe how a National Cancer Institute-designated cancer center partnered with rural community stakeholders to adapt a cancer prevention-focused research and community capacity-building workshop. The workshop's goal was to strengthen community-academic partnerships and facilitate the development of sustainable well-resourced rural cancer-focused research. Researchers from the Siteman Cancer Center partnered with community leaders from rural counties in southern Illinois. We adapted the workshop from an existing evidence-based program. We analyzed changes in knowledge and research capacity and relevance to their community work. From February to May 2019, community partners guided all elements of the workshop development. Workshop participants were mostly White race (93%), had a college degree or beyond (75%), reported living in a rural community (93%), and represented an academic, faith-based, or healthcare institution (78%). Participants' mean knowledge scores of the presented content increased significantly after each session, from 9.3 to 9.9 for session 1 (p = 0.05) and 6.8 to 9.7 (p < 0.001) for session two. Through the workshop, participant scores also increased in research capacity skills, confidence, and their understanding of conducting research in the community. The workshop, co-curated and led by rural community leaders and researchers from Siteman Cancer Center, successfully increased knowledge of and interest in building cancer research capacity. Lessons from our work can inform the implementation of similar programs that address rural cancer health through research and community capacity building between rural community partners and urban cancer centers.

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 ptrend < 0.03), while colorectal, cervical and breast cancer screening decreased (all ptrend < 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.

Racial and Ethnic Differences in Rural-Urban Trends in 5-Year Survival of Patients With Lung, Prostate, Breast, and Colorectal Cancers: 1975-2011 Surveillance, Epidemiology, and End Results (SEER).

Importance: Considering reported rural-urban cancer incidence and mortality trends, rural-urban cancer survival trends are important for providing a comprehensive description of cancer burden. Furthermore, little is known about rural-urban differences in survival trends by racial and ethnic groups. Objective: To examine national rural-urban trends in 5-year cancer-specific survival probabilities for lung, prostate, breast, and colorectal cancers in a diverse sample of racial and ethnic groups. Design, Setting, and Participants: This cross-sectional study used an epidemiologic assessment with 1975 to 2016 Surveillance, Epidemiology, and End Results (SEER) data to analyze patients diagnosed no later than 2011. Patients were classified as living in rural and urban counties based on the 2013 Rural-Urban Continuum Codes. Main Outcomes and Measures: The 5-year cancer-specific survival probability of urban and rural patients for each cancer type was estimated by fitting Cox proportional hazard regression models accounting for race, ethnicity, tumor characteristics, and other sociodemographic characteristics. A generalized linear regression model was used to estimate the mean estimated probability of survival for each stratum. Joinpoint regression analysis estimated periods of significant change in survival. Results: In this study, data from 3 659 417 patients with cancer (median [IQR] age, 67 [58-76]; 1 918 609 [52.4%] male; 237 815 [6.5%] Hispanic patients; 396 790 [10.8%] Black patients; 2 825 037 [77.2%] White patients) were analyzed, including 888 338 patients with lung cancer (24.3%), 750 704 patients with colorectal cancer (20.5%), 987 826 patients with breast cancer (27.0%) breast, and 1 023 549 patients with prostate cancer (28.0%). There were 430 353 rural patients (11.8%). Overall, there was an equal representation of rural and urban men. Rural patients were likely to be non-Hispanic White individuals, have more cases of distant tumors, and be older. Rural and non-Hispanic Black patients for all cancer types often had shorter survival. From 1975 to 2016, the 5-year lung cancer survival rate was shorter for non-Hispanic Black rural patients in 1975 at 48%, while increasing to 57% for both non-Hispanic Black urban and rural patients in 2011, but still the shortest among all cancer types. In 1975, the longest survival rate was observed in urban Asian and Pacific Islander patients with breast cancer at 86%, and in 2011, the longest survival rate was observed in urban non-Hispanic White patients with XX cancer at 92%. Conclusions and Relevance: Even after accounting for sociodemographic and tumor characteristics, these findings suggest that non-Hispanic Black patients with cancer are particularly vulnerable to cancer burden, and resources are urgently needed to reverse decades-old survival trends.

Consequences of Structural Urbanism: Urban-Rural Differences in Cancer Patients' Use and Perceived Importance of Supportive Care Services from a 2017-2018 Midwestern Survey.

BACKGROUND: Structural inequities, in part, undergird urban-rural differences in cancer care. The current study aims to understand the potential consequences of structural inequities on rural and urban cancer patients' access to and perceived importance of supportive cancer care resources. METHODS: We used data collected from November 2017 to May 2018 from a larger cross-sectional needs assessment about patients' support needs, use of services, and perceptions at a Midwestern United States cancer center. Oncology patients received a study packet during their outpatient clinic visit, and interested patients consented and completed the questionnaires. RESULTS: Among the sample of 326 patients, 27% of the sample was rural. In adjusted logistic regression models, rural patients were less likely to report using any secondary support services (15% vs. 27%; OR = 0.43, 95%CI [0.22, 0.85], p = 0.02) and less likely than urban counterparts to perceive secondary support services as very important (51% vs. 64%; OR = 0.57, 95%CI [0.33, 0.94], p = 0.03). CONCLUSION: Structural inequities likely have implications on the reduced access to and importance of supportive care services observed for rural cancer patients. To eliminate persistent urban-rural disparities in cancer care, rural residents must have programs and policies that address cancer care and structural inequities.

An examination of the implementation of a patient navigation program to improve breast and cervical cancer screening rates of Chinese immigrant women: a qualitative study.

BACKGROUND: Chinese Americans have lower breast and cervical cancer screening rates than the national average and experience multiple barriers to cancer care. Patient navigators have improved screening and follow-up rates for medically underserved populations, yet investigations of cancer navigation programs and their implementation among Chinese Americans are limited. To address this gap, we used the Consolidated Framework for Implementation Research (CFIR) to examine facilitators and barriers to implementing the Chicago-based Chinatown Patient Navigation Program (CPNP) for breast and cervical cancer screening, follow-up, and treatment. METHODS: Stakeholders from clinical care, supportive care services, and community organizations were invited to participate in qualitative interviews to illuminate implementation processes and stakeholder perspectives of facilitators and barriers to implementing the CPNP. Interviews were audio-recorded, transcribed, and deductively coded according to CFIR domains, including (1) intervention characteristics; (2) outer setting; (3) inner setting; and (4) the implementation process. RESULTS: We interviewed a convenience sample of 16 stakeholders representing a range of roles in cancer care, including nurses, clinical team members, administrators, physicians, a community-based organization leader, and a CPNP navigator. Findings detail several facilitators to implementing the CPNP, including patient navigators that prepared Chinese-speaking patients for their clinic visits, interpretation services, highly accessible patient navigators, and high-quality flexible services. Barriers to program implementation included limited regular feedback provided to stakeholders regarding their program involvement. Also, early in the program's implementation there was limited awareness of the CPNP navigators' roles and responsibilities, insufficient office space for the navigators, and few Chinese language patient resource materials. CONCLUSIONS: These findings provide valuable information on implementation of future patient navigation programs serving Chinese American and other limited-English speaking immigrant populations.

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

PURPOSE: Rural residents have a higher cancer burden than urban residents, which is likely related to multiple socioecological factors. This study sought to investigate the perspectives of a diverse set of rural stakeholders regarding access to cancer prevention and control resources in rural southern Illinois. METHODS: Stakeholders were recruited from counties in southern Illinois and included residents (cancer survivors or caregivers), leaders of community-based organizations with health-related missions, and health care providers. Individual interviews and focus groups assessed recommended cancer prevention, control, and treatment resources; helpfulness of regional resources; and needed resources. The research team used an iterative approach to thematic analysis wherein codes were derived inductively and refined repeatedly to reveal overarching themes. FINDINGS: Forty-four stakeholders reported challenges to health care access (eg, travel distance, financial burdens, and poor quality of care) and limited access to supportive care services (lack of caregiver support and "spotty" area resources). To mitigate these barriers, local residents used a combination of individual (self-reliance and adaptive measures) and organizational (patient navigation and financial services) approaches. Finally, stakeholders reported multiple forms of cancer control and prevention communication, including formal discussions with health care providers and various types of informal social support (eg, friends and family). CONCLUSIONS: Stakeholders experienced barriers to cancer prevention and control often mitigated by a reliance on personal adaptations, nonclinical organizational supports, and informal support systems. While resources remain minimal in southern Illinois, researchers and practitioners must make efforts to leverage existing community organizations and social networks to improve cancer outcomes in this region.

Racial Residential Segregation and Colorectal Cancer Mortality in the Mississippi Delta Region.

INTRODUCTION: Few studies have examined the effects of racial segregation on colorectal cancer (CRC) outcomes, and none has determined whether rurality moderates the effect of racial segregation on CRC mortality. We examined whether the effect of segregation on CRC mortality varied by rurality in the Mississippi Delta Region, an economically distressed and historically segregated region of the United States. METHODS: We used data from the US Census Bureau and the 1999-2018 Surveillance, Epidemiology, and End Results (SEER) program to estimate mixed linear regression models in which CRC mortality rates among Black and White residents in Delta Region counties (N = 252) were stratified by rurality and regressed on White-Black residential segregation indices and 4 socioeconomic control variables. RESULTS: Among Black residents, CRC mortality rates in urban counties were a function of a squared segregation term (b = 162.78, P = .01), indicating that the relationship between segregation and CRC mortality was U-shaped. Among White residents, main effects of annual household income (b = 29.01, P = .04) and educational attainment (b = 34.58, P = .03) were associated with CRC mortality rates in urban counties, whereas only annual household income (b = 19.44, P = .04) was associated with CRC mortality rates in rural counties. Racial segregation was not associated with CRC mortality rates among White residents. CONCLUSION: Our county-level analysis suggests that health outcomes related to racial segregation vary by racial, contextual, and community factors. Segregated rural Black communities may feature stronger social bonds among residents than urban communities, thus increasing interpersonal support for cancer prevention and control. Future research should explore the effect of individual-level factors on colorectal cancer mortality.

Breast Cancer Mortality Hot Spots Among Black Women With de Novo Metastatic Breast Cancer.

Background: Black women living in southern states have the highest breast cancer mortality rate in the United States. The prognosis of de novo metastatic breast cancer is poor. Given these mortality rates, we are the first to link nationally representative data on breast cancer mortality hot spots (counties with high breast cancer mortality rates) with cancer mortality data in the United States and investigate the association of geographic breast cancer mortality hot spots with de novo metastatic breast cancer mortality among Black women. Methods: We identified 7292 Black women diagnosed with de novo metastatic breast cancer in Surveillance, Epidemiology, and End Results (SEER). The county-level characteristics were obtained from 2014 County Health Rankings and linked to SEER. We used Cox proportional hazards models to calculate adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs) for mortality between hot spot and non-hot spot counties. Results: Among 7292 patients, 393 (5.4%) resided in breast cancer mortality hot spots. Women residing in hot spots had similar risks of breast cancer-specific mortality (aHR = 0.99, 95% CI = 0.85 to 1.15) and all-cause mortality (aHR = 0.97, 95% CI = 0.84 to 1.11) as women in non-hot spots after adjusting for individual and tumor-level factors and treatments. Additional adjustment for county-level characteristics did not impact mortality. Conclusion: Living in a breast cancer mortality hot spot was not associated with de novo metastatic breast cancer mortality among Black women. Future research should begin to examine variation in both individual and population-level determinants, as well as in molecular and genetic determinants that underlie the aggressive nature of de novo metastatic breast cancer.

Predictors of annual prostate-specific antigen (PSA) screening among black men: results from an urban community-based prostate cancer screening program.

BACKGROUND AND OBJECTIVE: Black men have an increased risk of prostate cancer mortality compared with any racial or ethnic group. Further, research on prostate cancer prevention and control messaging focusing on Black men is limited. Community screening events are successful in attracting members from high-risk groups, like Black men, and are a valuable source to collect cancer screening and health promotion data. Therefore, the authors examined data of Black men attending a community-based PCa screening event to evaluate predictors of annual PCa screening, and identify sub-populations of Black men needing targeted cancer prevention messaging. METHODS: Black men attending PCa screening events in St. Louis, MO 2007-2017 were eligible. Participants completed either a mail-in or on-site survey at the time of their screening to collect information on annual screening history. We analyzed sociodemographic factors, having a first-degree relative with a history of PCa, healthcare utilization characteristics, and predictors of annual PSA screening. Logistic regression analysis was used to assess the association between predictors and annual PSA screening. RESULTS: Data was analyzed from 447 respondents. One-third of the residents did not know their cancer family history status. Older age and having a primary healthcare provider predicted an annual prostate cancer after attending the PCa community screening event. In the fully adjusted model, all ages older than 45 years were 2-4 times more likely to have an annual PCa screening. Having a healthcare provider also predicted an annual PCa screening (OR: 4.59, 95% CI: 2.30-9.14). CONCLUSION: Regardless of sociodemographic and family history factors, older Black men and those with a primary physician are more likely to have an annual PSA screening. Cancer prevention promotion efforts for Black men should target mechanisms that facilitate family cancer history conversations to engage younger Black men. Also, additional health promotions efforts are needed to educate Black men without a primary healthcare provider.

Assessing the relationship between patient-provider communication quality and quality of life among rural cancer survivors.

PURPOSE: We explored relationships between patient-provider communication quality (PPCQ) and three quality of life (QOL) domains among self-identified rural cancer survivors: social well-being, functional well-being, and physical well-being. We hypothesized that high PPCQ would be associated with greater social and functional well-being, but be less associated with physical well-being, due to different theoretical mechanisms. METHODS: All data were derived from the 2017-2018 Illinois Rural Cancer Assessment (IRCA). To measure PPCQ and QOL domains, we respectively used a dichotomous measure from the Medical Expenditure Panel Survey's Experience Cancer care tool (high, low/medium) and continuous measures from the Functional Assessment of Cancer Therapy-General (FACT-G). RESULTS: Our sample of 139 participants was largely female, non-Hispanic White, married, and economically advantaged. After adjusting for demographic and clinical variables, patients who reported high PPCQ exhibited greater social well-being (Std. ß = 0.20, 95% CI: 0.03, 0.35, p = 0.02) and functional well-being (Std. ß = 0.20, 95% CI: 0.05, 0.35, p = 0.03) than patients with low/medium PPCQ. No association was observed between PPCQ and physical well-being (Std. ß = 0.06, 95% CI: - 2.51, 0.21, p = 0.41). Sensitivity analyses found similar, albeit attenuated, patterns. CONCLUSION: Our findings aligned with our hypotheses. Future researchers should explore potential mechanisms underlying these differential associations. Specifically, PPCQ may be associated with social and functional well-being through interpersonal mechanisms, but may not be as associated with physical well-being due to multiple contextual factor rural survivors disproportionately face (e.g., limited healthcare access, economic hardship) and stronger associations with clinical factors.

Urban-Rural Disparities in Access to Low-Dose Computed Tomography Lung Cancer Screening in Missouri and Illinois.

INTRODUCTION: Low-dose computed tomography (LDCT) lung cancer screening is recommended for current and former smokers who meet eligibility criteria. Few studies have quantitatively examined disparities in access to LDCT screening. The objective of this study was to examine relationships between 1) rurality, sociodemographic characteristics, and access to LDCT lung cancer screening and 2) screening access and lung cancer mortality. METHODS: We used census block group and county-level data from Missouri and Illinois. We defined access to screening as presence of an accredited screening center within 30 miles of residence as of May 2019. We used mixed-effects logistic models for screening access and county-level multiple linear regression models for lung cancer mortality. RESULTS: Approximately 97.6% of metropolitan residents had access to screening, compared with 41.0% of nonmetropolitan residents. After controlling for sociodemographic characteristics, the odds of having access to screening in rural areas were 17% of the odds in metropolitan areas (95% CI, 12%-26%). We observed no association between screening access and lung cancer mortality. Southeastern Missouri, a rural and impoverished area, had low levels of screening access, high smoking prevalence, and high lung cancer mortality. CONCLUSION: Although access to LDCT is lower in rural areas than in urban areas, lung cancer mortality in rural residents is multifactorial and cannot be explained by access alone. Targeted efforts to implement rural LDCT screening could reduce geographic disparities in access, although further research is needed to understand how increased access to screening could affect uptake and rural disparities in lung cancer mortality.

A Comparative Analysis of Online Medical Record Utilization and Perception by Cancer Survivorship.

BACKGROUND: Cancer survivors face many challenges including coordinating care across multiple providers and maintaining medical records from multiple institutions. Access and utilization of online medical records could help cancer survivors manage this complexity. Here, we examined how cancer survivors differ from those without a history of cancer with regards to utilization and perception of medical records. METHODS: We conducted a cross-sectional study of 3491 respondents, from the Health Information National Trends survey 5, cycle 2. The association of medical record utilization and perceptions with cancer survivorship was assessed using survey-weighted logistic regression. RESULTS: Cancer survivors (n=593) were more likely to report that a provider maintains a computerized medical record [adjusted odds ratio (AOR)=2.05; 95% confidence (CI), 1.24-3.41] and were more likely to report confidence in medical record safeguards (AOR=1.44; 95% CI, 1.03-2.03). However, cancer survivors were no more likely to access online medical records than those without a history of cancer (AOR=1.13; 95% CI, 0.69-1.86). Cancer survivors were no more likely to report privacy concerns as a reason for not accessing online medical records, however, survivors were more likely to report a preference for speaking directly with a provider as a reason for not accessing online medical records (AOR=2.24; 95% CI, 0.99-5.05). CONCLUSIONS: Although cancer survivors are more likely to trust medical record safe guards and do not express increased concerns about online medical record privacy, a preference to speak directly with provider is a barrier of use.

The use of survivorship care plans by female racial and ethnic minority breast cancer survivors: a systematic review.

PURPOSE: Racial/ethnic breast cancer survivorship disparities persist as minority breast cancer survivors (MBCSs) report fragmentation in survivorship care, namely in the access and delivery of survivorship care plans (SCPs). To better understand care coordination of MCBS, this review elucidated concerns of female MBCS about their preparation for post-treatment survivorship care, the preferred practices for the delivery of a SCP, and the associated content to improve post-treatment survivorship care understanding. METHODS: A systematic search of articles from PubMed, Ovid-Medline, CINAHL databases, and bibliographic reviews included manuscripts using keywords for racial/ethnic minority groups and breast cancer survivorship care coordination terms. Salient themes and article quality were analyzed from the extracted data. RESULTS: Fourteen included studies represented 5,854 participants and over 12 racial/ethnic groups. The following themes of post-treatment MBCS were identified from the review: (1) uncertainty about post-treatment survivorship care management is a consequence of sub-optimal patient-provider communication; (2) access to SCPs and related materials are desired, but sporadic; and (3) advancements to the delivery and presentation of SCPs and related materials are desired. CONCLUSIONS: Representation of only 14 studies indicates that the MBCSs' perspective post-treatment survivorship care is underrepresented in the literature. Themes from this review support access to, and implementation of, culturally tailored SCP for MBCS. There was multi-ethnic acceptance of SCPs as a tool to help improve care coordination. IMPLICATIONS FOR CANCER SURVIVORS: These findings highlight the importance of general education about post-treatment survivorship, post-treatment survivorship needs identification, and the elucidation of gaps in effective SCP delivery among MBCS.

Physical health composite and risk of cancer mortality in the REasons for Geographic and Racial Differences in Stroke Study.

It is unclear how resting myocardial workload, as indexed by baseline measures of rate-pressure product (RPP) and physical activity (PA), is associated with the overall risk of cancer mortality. We performed prospective analyses among 28,810 men and women from the REasons for Geographic and Racial Differences in Stroke (REGARDS) cohort. We used a novel physical health (PH) composite index and categorized participants into one of four groups based on combinations from self-reported PA and RPP: 1) No PA and High RPP; 2) No PA and Low RPP; 3) Yes PA and High RPP; and 4) Yes PA and Low RPP. We examined the association between baseline PH composite and cancer mortality adjusted for potential confounders using Cox regression. A total of 1191 cancer deaths were observed over the 10-year observation period, with the majority being lung (26.87%) and gastrointestinal (21.49%) cancers. Even after controlling for sociodemographics, health behaviors, baseline comorbidity score, and medications, participants with No PA and High RPP had 71% greater risk of cancer mortality when compared to participants with PA and Low RPP (adjusted HR: 1.71, 95% CI: 1.42-2.06). These associations persisted after examining BMI, smoking, income, and gender as effect modifiers and all-cause mortality as a competing risk. Poorer physical health composite, including the novel RPP metric, was associated with a nearly 2-fold long-term risk of cancer mortality. The physical health composite has important public health implications as it provides a measure of risk beyond traditional measure of obesity and physical activity.
