Abstract PO1-08-03: Using Telehealth to Establish a High Risk Cancer Prevention Clinic over a large Geographic Area

Abstract There are health disparities in breast cancer screening based on urban, rural or frontier geographic designations. For instance, in Utah, the percentage of women who had no mammography in the last two years was 33.5% for urban, 33.8% for rural and 40.4% for frontier designations. Rural women are also diagnosed with breast cancer at later stages. Diagnosing breast cancer at earlier stages leads to improved survival, more affordable care, less toxic treatments, better quality of life and less time away from home and work. We are presenting the innovative use of telehealth to establish a High Risk Cancer Prevention Clinic to effectively reach a large geographic area and mitigate obstacles to accessing care. The clinic's mission is to identify and care for individuals with increased cancer risk due to familial, genetic and/or high risk lesions. This initiative provides centralized comprehensive evaluation, counseling and screening planning as well as referral for risk-reducing interventions closer to home. With a collaborative approach involving surgical and medical oncology, genetics, radiology and women's health specialists, the teleclinic has successfully served 280 patients since Spring 2022. Recently our health care system has increased significantly in geographic reach due to mergers with other health systems. We think this teleclinic is nimble enough and easily scalable to accommodate caring for increased numbers of patients needing this service.

Factors influencing breast cancer screening practices among women worldwide: a systematic review of observational and qualitative studies

BackgroundThe variation in breast cancer incidence rates across different regions may reflect disparities in breast cancer screening (BCS) practices. Understanding the factors associated with these screening behaviors is crucial for identifying modifiable elements amenable to intervention. This systematic review aims to identify common factors influencing BCS behaviors among women globally.MethodsRelevant papers were sourced from PubMed, Scopus, Embase, and Google Scholar. The included studies were published in English in peer-reviewed journals from January 2000 to March 2023 and investigated factors associated with BCS behaviors.ResultsFrom an initial pool of 625 articles, 34 studies (comprising 29 observational and 5 qualitative studies) with 36,043 participants were included. Factors influencing BCS behaviors were categorized into nine groups: socio-demographic factors, health status history, knowledge, perceptions, cultural factors, cues to action, motivation, self-efficacy, and social support. The quality appraisal scores of the studies ranged from average to high.ConclusionsThis systematic review highlights factors pivotal for policy-making at various levels of breast cancer prevention and assists health promotion professionals in designing more effective interventions to enhance BCS practices among women.

Appropriate Use of Medical Interpreters in the Breast Imaging Clinic.

More than 25 million Americans have limited English-language proficiency (LEP) according to the U.S. Census Bureau. This population experiences challenges accessing health care and is least likely to receive preventive health care, including screening mammogram. In a setting where the breast radiologist does not speak the language of their patient, using certified medical interpreter services is fundamental. Medical interpreter use is associated with improved clinical care and patient satisfaction and can potentially increase adherence to screening mammograms and follow-up in patients with LEP. Title VI of the Civil Rights Act requires interpreter services for patients with LEP who are receiving federal financial assistance. Failure to provide interpretative services when necessary is considered discriminatory and illegal. The use of untrained medical interpreters, including ad hoc interpreters (eg, family, friends, or untrained staff), is associated with more medical errors, violation of confidentiality, and poor health outcomes. Types of medical interpretation services available to address language barriers include in-person interpretation, telephone and video remote interpretation, and qualified bilingual staff. Proper training and certification of medical interpreters is essential to prevent misinterpretations and ensure patient safety. When using an interpreter service, speak to and maintain eye contact with the patient, address the patient directly and seat the interpreter next to or slightly behind the patient, use visual aids whenever possible, and have the patient repeat the information to verify comprehension. Breast radiologists can address disparities in breast cancer screening and treatment by promoting effective communication.

Abstract C134: Efficacy of mobile mammography and state-funded cancer services in reducing disparities in follow-up adherence: A retrospective analysis

Abstract Objective: Mobile mammography programs, such as the one at Stony Brook Cancer Center (SBCC), play an important role in providing breast cancer screening services to underserved communities. Follow-up to abnormal mammogram screenings is critical for early cancer detection, but patients often encounter barriers that prevent timely diagnostic procedures. We aim to evaluate the role of New York State’s Cancer Services Program (CSP) in facilitating follow-up care among underserved patients who participated in SBCC’s mobile mammography initiative. Methods: We conducted a retrospective analysis of 817 mobile mammography patients who required additional testing following an abnormal mammogram over a five-year period. Of these, 68% were beneficiaries of the CSP, while 32% were insured. Results: Our findings revealed that among CSP beneficiaries, only 3.5% were lost to follow-up, compared to a significant 16.5% of insured patients who did not adhere to recommended follow-up care. This suggests that the CSP’s supportive role is critical in ensuring follow-up care among underserved communities. Conclusions: The CSP’s substantial impact on follow-up care adherence highlights the program's effectiveness in reducing healthcare disparities. However, more work is needed to enhance follow-up care adherence among insured patients. Solutions may include identifying and addressing barriers to care and implementing targeted interventions to improve patient outcomes. Implications for Policy or Practice: Mobile mammography programs, such as SBCC’s initiative, demonstrate a potential strategy for reducing health disparities in breast cancer screening and detection. Securing access to follow-up care is crucial for improving patient outcomes. Addressing barriers to care, strengthening patient education, and enhancing outreach efforts can increase participation in screening initiatives, thus advancing health equity and reducing disparities in breast cancer outcomes.

Exploring Disparities in Breast Cancer Screening: An Ecological Analysis of Australian Data.

The objective of this study is to analyse the socio-spatial patterns of breast cancer screening across Australian regions. The research is an ecological study. Data for breast screening participation and associated social and demographic factors are obtained from the Australian Institute of Health and Welfare and the Australian Bureau of Statistics. The unit of measurement for the analysis is spatially aggregated regions (Statistical Area 3). Geographically weighted regression is used to analyse the relationship between a dependent variable and one or more independent variables while considering the spatial or geographic relationships among the data points. Globally, there was a significant (p<0.05) association between screening participation and income, English ability, education level, Indigenous background, and transport availability. The geographically weighted regression model represented an improved fit with a higher R2 (R2=0.89) and the Akaike information criterion (AIC) has improved, (AIC= 391.92). The Monte-Carlo tests for spatial variability were significant for all independent variables (p<0.05). Visually, there was marked spatial variation in the association between breast cancer screening rates and the significant independent variables from the global model. The identification of significant spatial variability in the association between breast cancer screening participation and important social and demographic factors provides important input into the design of programs aimed at increasing participation in screening regimes.

Abstract C112: Improving breast cancer screening disparities through A3 problem solving: Design of a quality improvement initiative

Abstract Introduction: Extensive research studies on breast cancer disparities have had limited impact on reducing breast cancer disparities. Quality improvement initiatives use data-driven, rigorous approaches to plan, execute, and study the delivery of healthcare services. There have been limited studies using quality improvement methods to address health disparities. The purpose of our study was to describe the design of a quality improvement initiative to address breast cancer disparities using the A3 problem solving method. Methods: A3 problem solving method was used to reduce breast cancer screening disparities. The A3 method is a quality improvement tool used to identify problems, organize and synthesize data, and propose solutions to achieve goals (summarized on one side of a sheet of paper). A3 methods are outlined by the FOCUS-PDCA acronym: F - Find process to improve, O - Organize team of stakeholders, C - Clarify current state, U - Understand sources of variation that contribute to the problem, S - Select change ideas, P - Plan and do the improvement, C - Check the results, A - Act. Quantitative data was derived from the electronic medical record. Qualitative data was derived from divergent thinking exercises asking participants from diverse standing urban stakeholder groups about barriers to cancer screening. Results: Design of the A3 problem solving process was conducted between November 2022 until May 2023 yielding the following FOCUS-PDCA design and initial results. F - Increase the percentage of patients who have undergone mammography screening within the last two years. O - Team includes representative leaders from primary care, community health, ambulatory operations, diversity, equity, and inclusion, radiology, breast center, population health, information services, and federally qualified health centers. C and U - Quantitative data collection revealed that 74% of 37,509 eligible patients (women between 50-74 years old) received a mammogram within the last two years (75% White, 58% Black, 67% Asian, 60% American Indian, 64% Hispanic). Divergent thinking exercises revealed the following root causes for mammography screening disparities: patients don’t know they are due, transportation issues, barriers to scheduling, access to mammography facilities, financial concerns, and fears about returning to clinics during COVID-19. S - Process improvements included multilingual and modality reminders, marketing campaigns, transportation vouchers, co-location of screening centers with federally qualified health centers, expanded access to mammography screening facilities, educational activities for primary care physicians, participation in community events, equity-focused review of screening guidelines. PDCA - Based on selected improvements, changes in breast cancer screening percentages will be displayed using run charts until December 2024, stratified by race and ethnicity. Conclusion: A3 problem solving tools represent structured, scientifically rigorous approaches that cancer centers can use to reduce screening disparities. Citation Format: Nia Foster, Arissa J.

Disparities in Breast Cancer Screening Rates Among Adults With and Without Intellectual and Developmental Disabilities.

Individuals with intellectual and developmental disabilities may face barriers in accessing healthcare, including cancer screening and detection services. We sought to assess the association of intellectual and developmental disabilities (IDD) with breast cancer screening rates. Data from 2018 to 2020 was used to identify screening-eligible individuals from Medicare Standard Analytic Files. Adults aged 65-79 years who did not have a previous diagnosis of breast cancer were included. Multivariable regression was used to analyze the differences in breast cancer screening rates among individuals with and without IDD. Among 9,383,349 Medicare beneficiaries, 11,265 (0.1%) individuals met the criteria for IDD. Of note, individuals with IDD were more likely to be non-Hispanic White (90.5% vs. 87.3%), have a Charlson Comorbidity Index score ≤ 2 (66.2% vs. 85.5%), and reside in a low social vulnerability index neighborhood (35.7% vs. 34.4%). IDD was associated with reduced odds of undergoing breast cancer screening (odds ratio (OR) 0.77, 95% confidence interval (CI) 0.74-0.80; p < 0.001). Breast cancer screening rates in individuals with IDD were further influenced by social vulnerability and belonging to a racial/ethnicminority. Individuals with IDD may face additional barriers to breast cancer screening. The combination of IDD and social vulnerability placed patients at particularly high risk of not being screened for breast cancer.

Inequities in colorectal and breast cancer screening: At the intersection of race/ethnicity, sexuality, and gender

ObjectiveTo investigate the joint impact of sexual orientation, gender identity, and race/ethnicity on colorectal and breast cancer screening disparities in the United States. MethodsUtilizing sampling weighted data from the 2016 and 2018 Behavioral Risk Factor Surveillance System, we assessed differences in two metrics via chi-square statistics: 1) lifetime uptake, and 2) up-to-date colorectal and breast cancer screening by sexual orientation and gender identity, within and across racial/ethnic classifications. ResultsWithin specific races/ethnicities, lifetime CRC screening was higher among gay/lesbian (within NH-White, Hispanic, and Asian/Pacific Islander) and bisexual individuals (Hispanic) compared to straight individuals, and lowest overall among transgender women and transgender nonconforming populations (p < 0.05). Asian transgender women had the lowest lifetime CRC screening (13.0%; w.n. = 1,428). Lifetime breast cancer screening was lowest among the Hispanic bisexual population (86.6%; w.n. = 26,940) and Hispanic transgender nonconforming population (71.8%; w.n. = 739); within all races, SGM individuals (except NH-White, Hispanic, and Black bisexual populations, and NH-White transgender men) had greater breast cancer screening adherence compared to straight individuals. ConclusionsDue to small, unweighted sample sizes, results should be interpreted with caution. Heterogeneity in screening participation by SGM status within and across racial/ethnic groups were observed, revealing the need to disaggregate data to account for intersecting identities and for studies with larger sample sizes to increase estimate reliability.

Unique Breast Cancer Screening Disparities in a Safety-Net Health System

Breast cancer screening (BCS) disparities leave historically underserved groups more vulnerable to adverse outcomes. This study explores granular associations between BCS and patient sociodemographic factors in a large urban safety-net health system. A retrospective review among female patients ages 50-74 within an urban safety-net health system was conducted in 2019. All patients had a primary care visit in the past 2 years. Multiple patient health and sociodemographic characteristics were reviewed, as well as provider gender and specialty. Bivariate analyses and multivariable logistic regression were performed in 2022. The BCS rate among 11,962 women was 69.7%. Over half of patients were non-White (63.6%) and had public insurance (72.3%). Patients with limited English proficiency made up 44.3% of the cohort. Compared to their sociodemographic counterparts, patients with White race, English proficiency, and Medicare insurance had the lowest rates of BCS. Serious mental illness and substance use disorder were associated with lower odds of BCS. In multivariable analysis, when using White race and English speakers as a reference, most other races (Black, Hispanic, and Other) and languages (Spanish, Portuguese, and Other) had significantly higher odds of screening ranging from 8% to 63% higher, except Asian race and Haitian Creole language. Female (versus male) and internal medicine-trained providers were associated with higher screening odds. Multiple unique variables contribute to BCS disparities, influenced by patient and health system factors. Defining and understanding the interplay of these variables can guide policymaking and identify avenues to improve BCS for vulnerable or traditionally under-resourced populations.

Reducing Racial Disparities in Breast Cancer Treatment

Racial disparities in breast cancer screening, treatment, and outcomes are well established. A recent multi-institutional paper showed a higher mean heart dose (MHD) in Black women and other minorities compared to White women who underwent left-sided breast or chest wall irradiation. We evaluated the MHD of women treated in our institution and investigated whether institution-wide measures can mitigate disparities. We identified 509 consecutively treated female patients from 2012 to 2021 who received left-sided breast or chest wall irradiation (with or without regional nodal irradiation). Medical records were queried to report cardiac dosimetry across various racial groups. Details regarding the use of active breathing control (ABC), breast size, internal mammary nodal irradiation, and whether the patient's treatment plan met the departmental boarding pass requirement and was prospectively presented at departmental peer review were noted. MHD were noted in absolute values and 2-Gy equivalent doses (EQD2). Kruskal-Wallis test was used to analyze differences in MHD between racial groups. Univariate and multivariable Cox regression analyses were performed to determine association of MHD with other factors. MHD was similar across racial groups; 1.38 Gy (1.12, 2.02) in Black women, 1.35 Gy (1.02, 1.97) in White women, and 1.39 Gy (1.07, 2.01) in others with an EQD2 of 0.71, 0.70 and 0.72 (P = 0.6). Rates of the use of hypofractionation, a cavity boost, regional nodal irradiation, internal mammary nodal irradiation, meeting departmental boarding pass requirement, and peer review of treatment plan before starting treatment were similar across all racial groups. The use of ABC was 83% in White women, 75% in Black women and 62% in other races (P = 0.005). The difference in ABC use was attributed to a higher rate of volumetric modulated arc therapy treatment in other races (33%). Median breast size was 1904 cc in Black women, 1504 cc in White women, and 1331 cc in other racial groups (P = 0.001). On univariate and multivariate analysis, MHD differed with IMN treatment, boost and use of ABC but remained similar across racial groups and varying breast size. Despite anatomical differences such as breast size, achieving similar cardiac dose is feasible across racial groups by uniformly utilizing ABC for left sided breast or chest wall irradiation, applying standardized boarding pass constraints and peer review of all cases. Further studies to identify factors that may lead to differences in the rates of cardiac morbidity among racial groups are warranted.

From Awareness to Action: A Review of Efforts to Reduce Disparities in Breast Cancer Screening.

Breast cancer is a significant public health concern, and addressing disparities in breast cancer screening is crucial for improving early detection and reducing mortality rates. This review article examines efforts to bridge the gap between awareness and action in reducing disparities in breast cancer screening. A systematic approach was employed to gather relevant literature using various databases. The selected studies encompassed a range of interventions, including policy changes, community-based programs, culturally competent interventions, technological advancements, and patient navigation. The review highlights the importance of policies and legislation in improving access to screening services and the impact of community-based initiatives in addressing disparities. Culturally competent interventions, tailored messaging, and language support were found to be effective in improving screening rates among diverse populations. Technological advancements, such as telemedicine and mobile health applications, were identified as promising approaches to increase access to screening services. Patient navigation programs effectively addressed barriers to screening and improved screening rates. The review also discusses evaluating efforts, limitations, and the need for continuous improvement. Future directions and recommendations include addressing gaps in the existing literature, proposing research directions, and providing recommendations for policymakers, healthcare providers, and researchers. By implementing these recommendations and working collaboratively, we can strive for equitable access to breast cancer screening for all populations, ultimately leading to improved outcomes and reduced disparities.

Disparities in Breast Cancer Screening

Background. Despite the death rates of breast cancer declining in the last two decades, new breast cancer cases have disproportionately affected some marginalized populations such as African American women. Since mammography screening disparities by sexual orientation and gender identity are inconsistent, it is important to understand the patterns of mammography screening to inform public health interventions.&#x0D; Aims. This secondary data analysis study aimed to examine the disparities in mammography screening by sexual orientation and gender identity among females assigned at birth (FAAB) overall and stratified by race/ethnicity in the U.S.&#x0D; Methods. By using 2014, 2016, and 2018 Behavioral Risk Factor Surveillance Survey (BRFSS) data, we conducted adjusted multivariable logistic regression models to estimate the odds of receiving an up-to-date mammography screening in relation to sexual orientation, gender identity, and other correlates among FAAB aged 50-74 years (unweighted N=228,257).&#x0D; Results. Overall, the lifetime and up-to-date prevalence of mammography screening were 96.3% and 76.0% in U.S. FAAB, respectively. Non-Hispanic Black (NHB) participants reported a higher rate of up-to-date mammography screening (84.13%) whereas those who had an income less than $15,000 per year had the lowest (71.31%). Being insured, overweight/obese, and not a current smoker were positively associated with receiving an up-to-date mammography screening across racial and ethnic groups. Besides, being physically active was significant for an up-to-date mammography screening in non-Hispanic White (NHW) and Hispanic participants. Also, Hispanic transgender participants were more likely to have an up-to-date mammography screening than their same-ethnic cisgender counterparts.&#x0D; Contribution to Evidence-Based Care. The findings reveal that the disparities in receiving an up-to-date mammography screening varied by sexual identity, gender identity, and race/ethnicity in FAAB aged 50-74 years. The lower rate of an up-to-date mammography screening was found particularly in Hispanic, bisexual AFAB. Future tailored mammogram programs should integrate physical activity and cultural components for people with multiple minority identities.

The Landmark Series-Addressing Disparities in Breast Cancer Screening: New Recommendations for Black Women.

Randomized, clinical trials have established the efficacy of screening mammography in improving survival from breast cancer for women through detection of early, asymptomatic disease. However, disparities in survival rates between black women and women from other racial and ethnic groups following breast cancer diagnosis persist. Various professional groups have different, somewhat conflicting, guidelines with regards to recommended age for commencing screening as well as recommended frequency of screening exams, but the trials upon which these recommendations are based were not specifically designed to examine benefit among black women. Furthermore, these recommendations do not appear to incorporate the unique epidemiological circumstances of breast cancer among black women, including higher rates of diagnosis before age 40 years and greater likelihood of advanced stage at diagnosis, into their formulation. In this review, we examined the epidemiologic and socioeconomic factors that are associated with breast cancer among black women and assess the implications of these factors for screening in this population. Specifically, we recommend that by no later than age 25 years, all black women should undergo baseline assessment for future risk of breast cancer utilizing a model that incorporates race (e.g., Breast Cancer Risk Assessment Tool [BCRAT], formerly the Gail model) and that this assessment should be conducted by a breast specialist or a healthcare provider (e.g., primary care physician or gynecologist) who is trained to assess breast cancer risk and is aware of the increased risks of early (i.e., premenopausal) and biologically aggressive (e.g., late-stage, triple-negative) breast cancer among black women.

Breast cancer screening during the COVID-19 pandemic: moving from disparities to health equity.

The COVID-19 pandemic created unprecedented disruptions to routine health care in the United States. Screening mammography, a cornerstone of breast cancer control and prevention, was completely halted in the spring of 2020, and screening programs have continued to face challenges with subsequent COVID-19 waves. Although screening mammography rates dropped for all women during the pandemic, a number of studies have now clearly documented that reductions in screening have been greater for some populations than others. Specifically, minoritized women have been screened at lower rates than White women across studies, although the specific patterns of disparity vary depending on the populations and communities studied. We posit that these disparities are likely due to a variety of structural and contextual factors, including the differential impact of COVID-19 on communities. We also outline key considerations for closing gaps in screening mammography. First, practices, health systems, and communities must measure screening mammography use to identify whether gaps exist, and which populations are most affected. Second, we propose that strategies to close disparities in breast cancer screening must be multifaceted, targeting the health system/practice, but also structural factors at the policy level. Health disparities arise from a complex set of conditions, and multimodal solutions that address the complex, multifactorial conditions that lead to disparities may be more likely to succeed and are necessary for promoting health equity.

Disparities in Breast Cancer Screening Between Caucasian and Asian American Women.

Asian American women have lower breast cancer incidence and mortality than their non-Hispanic White (NHW) counterparts. We sought to determine whether differences in screening practices could explain, in part, the variation in breast cancer detection rate. The 2015 National Health Interview Survey, an annual survey that is representative of the civilian, noninstitutionalized American population, was used to determine whether mammography usage was different between Asian and NHW women. Women ≥40y of age who identified as either Asian or NHW were included. A total of 7990 women ≥40y of age (6.12% Asian, 93.88% NHW), representing 53,275,420 women in the population, were included in our cohort of interest; 71.49% of Asian and 74.46% of NHW women reported having had a mammogram within the past 2 y (P=0.324). Controlling for education, insurance, family income, marital status, and whether they were born in the United States, Asians were less likely to have had a mammogram within the past 2 y than their NHW counterparts (odds ratio=0.68; 95% confidence interval: 0.46-0.99, P=0.047). Of patients who had an abnormal mammogram, there was no difference in the biopsy rate (20.35% versus 25.97%, P=0.4935) nor in the rate of cancer diagnosis among those who had a biopsy (7.70% versus 12.86%, P=0.211) between Asian and NHW women, respectively. Our findings suggest that the lower breast cancer incidence among the Asian population may, in part, be explained by a lower screening mammography rate in this population.

Patient-Reported Experiences of Breast Cancer Screening, Diagnosis, and Treatment Delay, and Telemedicine Adoption during COVID-19.

Purpose: To evaluate and quantify potential sociodemographic disparities in breast cancer screening, diagnosis, and treatment due to the COVID-19 pandemic, and the use of telemedicine. Methods: We fielded a 52-item web-based questionnaire from 14 May 2020 to 1 July 2020 in partnership with several U.S.-based breast cancer advocacy groups. Individuals aged 18 or older were eligible for this study if they: (1) received routine breast cancer screening; OR (2) were undergoing diagnostic evaluation for breast cancer; OR (3) had ever been diagnosed with breast cancer. We used descriptive statistics to understand the extent of cancer care delay and telemedicine adoption and used multivariable logistic regression models to estimate the association of sociodemographic factors with odds of COVID-19-related delays in care and telemedicine use. Results: Of 554 eligible survey participants, 493 provided complete data on demographic and socioeconomic factors and were included in the analysis. Approximately half (n = 248, 50.3%) had a personal history of breast cancer. Overall, 188 (38.1%) participants had experienced any COVID-19-related delay in care including screening, diagnosis, or treatment, and 339 (68.8) reported having at least one virtual appointment during the study period. Compared to other insurance types, participants with Medicaid insurance were 2.58 times more likely to report a COVID-19-related delay in care (OR 2.58, 95% Cl: 1.05, 6.32; p = 0.039). Compared to participants with a household income of less than USD 50,000, those with a household income of USD 150,000 or more were 2.38 (OR 2.38, 95% Cl: 1.09, 5.17; p = 0.029) times more likely to adopt virtual appointments. Self-insured participants were 70% less likely to use virtual appointment compared to those in other insurance categories (OR 0.28, 95% Cl: 0.11, 0.73; p = 0.009). Conclusions: The COVID-19 pandemic has had a significant impact on breast cancer screening, diagnosis, and treatment, and accelerated the delivery of virtual care. Lower-income groups and patients with certain insurance categories such as Medicaid or self-insured could be more likely to experience care delay or less likely to use telemedicine. Careful attention must be paid to vulnerable groups to insure equity in breast cancer-related service utilization and telemedicine access during and beyond the COVID-19 pandemic.
