Financial burden among metastatic breast cancer patients: a qualitative inquiry of costs, financial assistance, health insurance, and financial coping behaviors.

PURPOSE: Metastatic breast cancer (MBC) patients often face substantial financial burden due to prolonged and expensive therapy. However, in-depth experiences of financial burden among MBC patients are not well understood. METHODS: Qualitative interviews were conducted to describe the experiences of financial burden for MBC patients, focusing on the drivers of financial burden, their experience using their health insurance, accessing financial assistance, and any resulting cost-coping behaviors. Interviews were transcribed and qualitatively analyzed using a descriptive phenomenological approach to thematic analysis. RESULTS: A total of n = 11 MBC patients or caregiver representatives participated in the study. MBC patients were on average 50.2 years of age (range: 28-65) and 72.7% non-Hispanic White. MBC patients were diagnosed as metastatic an average of 3.1 years (range: 1-9) before participating in the study. Qualitative analysis resulted in four themes including (1) causes of financial burden, (2) financial assistance mechanisms, (3) health insurance and financial burden, and (4) cost-coping behaviors. Both medical and non-medical costs drove financial burden among participants. All participants reported challenges navigating their health insurance and applying for financial assistance. Regardless of gaining access to assistance, financial burden persisted for nearly all patients and resulted in cost-coping behaviors. CONCLUSION: Our findings suggest that current systems for health insurance and financial assistance are complex and difficult to meet patient needs. Even when MBC patients accessed assistance, excess financial burden persisted necessitating use of financial coping-behaviors such as altering medication use, maintaining employment, and taking on debt.

Inclusion of marginalized populations in HPV vaccine modeling: A systematic review.

OBJECTIVE: Models simulating the potential impacts of Human Papillomavirus (HPV) vaccine have been used globally to guide vaccination policies and programs. We sought to understand how and why marginalized populations have been incorporated into HPV vaccine simulation models. METHODS: We conducted a systematic search of PubMed, CINAHL, Scopus, and Embase to identify studies using simulation models of HPV vaccination incorporating one or more marginalized population through stratification or subgroup analysis. We extracted data on study characteristics and described these overall and by included marginalized groups. RESULTS: We identified 36 studies that met inclusion criteria, which modeled vaccination in 21 countries. Models included men who have sex with men (MSM; k = 16), stratification by HIV status (k = 9), race/ethnicity (k = 6), poverty (k = 5), rurality (k = 4), and female sex workers (k = 1). When evaluating for a marginalized group (k = 10), HPV vaccination was generally found to be cost-effective, including for MSM, individuals living with HIV, and rural populations. In studies evaluating equity in cancer prevention (k = 9), HPV vaccination generally advanced equity, but this was sensitive to differences in HPV vaccine uptake and use of absolute or relative measures of inequities. Only one study assessed the impact of an intervention promoting HPV vaccine uptake. DISCUSSION: Incorporating marginalized populations into decision models can provide valuable insights to guide decision making and improve equity in cancer prevention. More research is needed to understand the equity impact of HPV vaccination on cancer outcomes among marginalized groups. Research should emphasize implementation - including identifying and evaluating specific interventions to increase HPV vaccine uptake.

Barriers to Cervical Cancer Screening by Sexual Orientation Among Low-Income Women in North Carolina.

We sought to examine cervical cancer screening barriers by sexual orientation among low-income women in North Carolina. The MyBodyMyTest-3 Trial recruited low-income women (< 250% of federal poverty level) aged 25-64 years who were 1+ year overdue for cervical cancer screening. We compared perceptions of cervical cancer screening among those who self-identified as lesbian, gay, bisexual, or queer (LGBQ; n = 70) to straight/heterosexual women (n = 683). For both LGBQ and straight respondents, the greatest barriers to screening were lack of health insurance (63% and 66%) and cost (49% and 50%). LGBQ respondents were more likely than straight respondents to report forgetting to screen (16% vs. 8%, p = .05), transportation barriers (10% vs. 2%, p = .001), and competing mental or physical health problems (39% vs. 27%, p = .10). Addressing access remains important for improving cervical cancer screening among those under-screened. For LGBQ women, additional attention may be needed for reminders, co-occurring health needs, and transportation barriers.

Costs and Projected Effect of a Federally Qualified Health Center-Based Mailed Colorectal Cancer Screening Program in Texas.

Introduction: Mailed stool testing for colorectal cancer (CRC) may improve screening uptake and reduce the incidence and mortality of CRC, especially among patients at federally qualified health centers (FQHCs). To expand screening programs it is important to identify cost-effective approaches. Methods: We developed a decision-analytic model to estimate the cost, effects on screening and patient outcomes (CRCs detected, CRCs prevented, CRC deaths prevented), and cost-effectiveness of implementing a state-wide mailed stool testing program over 5 years among unscreened, age-eligible (aged 50-75 y) patients at FQHCs in Texas. We compared various outreach strategies and organizational structures (centralized, regional, or a hybrid). We used data from our existing regional mailed stool testing program and recent systematic reviews to set parameters for the model. Costs included start-up and ongoing activities and were estimated in 2022 US dollars from the perspective of a hypothetical third-party payer. Cost-effectiveness was assessed by using both incremental and average cost-effectiveness ratios. Results: Using either a statewide centralized or hybrid organizational configuration to mail stool tests to newly eligible FQHC patients and patients who have responded at least once since program inception is likely to result in the best use of resources over 5 years, enabling more than 110,000 additional screens, detecting an incremental 181 to 194 CRCs, preventing 91 to 98 CRCs, and averting 46 to 50 CRC deaths, at a cost of $10 million to $11 million compared with no program. Conclusions: A statewide mailed stool testing program for FQHC patients can be implemented at reasonable cost with considerable effects on CRC screening outcomes, especially when its structure maximizes program efficiency while maintaining effectiveness.

Understanding the role of access in Hispanic cancer screening disparities.

BACKGROUND: Hispanic populations in the United States experience numerous barriers to care access. It is unclear how cancer screening disparities between Hispanic and non-Hispanic White individuals are explained by access to care, including having a usual source of care and health insurance coverage. METHODS: A secondary analysis of the 2019 National Health Interview Survey was conducted and included respondents who were sex- and age-eligible for cervical (n = 8316), breast (n = 6025), or colorectal cancer screening (n = 11,313). The proportion of ever screened and up to date for each screening type was compared.  Regression models evaluated whether controlling for reporting a usual source of care and type of health insurance (public, private, none) attenuated disparities between Hispanics and non-Hispanic White individuals. RESULTS: Hispanic individuals were less likely than non-Hispanic White individuals to be up to date with cervical cancer screening (71.6% vs. 74.6%) and colorectal cancer screening (52.9% vs. 70.3%), but up-to-date screening was similar for breast cancer (78.8% vs. 76.3%). Hispanic individuals (vs. non-Hispanic White) were less likely to have a usual source of care (77.9% vs. 86.0%) and more likely to be uninsured (23.6% vs. 7.1%). In regressions, insurance fully attenuated cervical cancer disparities. Controlling for both usual source of care and insurance type explained approximately half of the colorectal cancer screening disparities (adjusted risk difference: -8.3 [-11.2 to -4.8]). CONCLUSION: Addressing the high rate of uninsurance among Hispanic individuals could mitigate cancer screening disparities. Future research should build on the relative successes of breast cancer screening and investigate additional barriers for colorectal cancer screening. PLAIN LANGUAGE SUMMARY: This study uses data from a national survey to compare cancer screening use those who identify as Hispanic with those who identify as non-Hispanic White. Those who identify as Hispanic are much less likely to be up to date with colorectal cancer screening than those who identify as non-Hispanic White, slightly less likely to be up to date on cervical cancer screening, and similarly likely to receive breast cancer screening. Improving insurance coverage is important for health equity, as is further exploring what drives higher use of breast cancer screening and lower use of colorectal cancer screening.

Potential effectiveness of a therapeutic HPV intervention campaign in Uganda.

Cervical cancer is a major source of morbidity and mortality in Uganda. In addition to prophylactic HPV vaccination, secondary prevention strategies are needed to reduce cancer burden. We evaluated the potential cancer reductions associated with a hypothetical single-contact therapeutic HPV intervention-with 70% coverage and variable efficacy [30%-100%]-using a three-stage HPV modeling framework reflecting HPV and cervical cancer burden in Uganda. In the reference case, we assumed prophylactic preadolescent HPV vaccination starting in 2020 with 70% coverage. A one-time therapeutic intervention targeting 35-year-old women in 2025 (not age-eligible for prophylactic vaccination) averted 1801 cervical cancers per 100 000 women over their lifetime (100% efficacy) or 533 cancers per 100 000 (30% efficacy). Benefits were considerably smaller in birth cohorts eligible for prophylactic HPV vaccination (768 cases averted per 100 000 at 100% efficacy). Evaluating the population-level impact over 40 years, we found introduction of a therapeutic intervention in 2025 with 100% efficacy targeted annually to 30-year-old women averted 139 000 incident cervical cancers in Uganda. This benefit was greatly reduced if efficacy was lower (30% efficacy; 41 000 cases averted), introduction was delayed (2040 introduction; 72 000 cases averted) or both (22 000 cases averted). We demonstrate the potential benefits of a single-contact HPV therapeutic intervention in a low-income setting, but show the importance of high therapeutic efficacy and early introduction timing relative to existing prophylactic programs. Reduced benefits from a less efficacious intervention may be somewhat offset if available within a shorter time frame.

Racial differences in employment and cost-management behaviors in patients with metastatic breast cancer.

PURPOSE: Little is known about racial variations in the financial impact of cancer care. Using data from a national survey of racially diverse patients with metastatic breast cancer, we examined racial/ethnic patterns in employment and cost-management (i.e., financial coping) behaviors. METHODS: We conducted an online survey of patients with metastatic breast cancer. Participants reported on socio-demographic characteristics, employment, and financial coping behaviors. We employed adjusted modified Poisson regressions to evaluate racial/ethnic differences in changes in work for pay and financial coping. RESULTS: Our analysis included 1052 respondents from 41 states, including Non-Hispanic Blacks (NHB, 9%), Hispanics (7%), Asians/Pacific Islanders/Native Hawaiians (API/NH, 10%), American Indians/Alaskan Natives (AI/AN, 8%), and Non-Hispanic Whites (NHW, 66%). In adjusted analyses comparing NHWs with patients of color, patients of color were more likely to take unpaid leave (NHB Adjusted Risk Ratio [ARR] = 2.27; 95% CI 1.54, 3.34), take paid leave (Hispanic ARR = 2.27; 95% CI 1.54, 1.29), stop work (AI/AN ARR = 1.22; 95% CI 1.05, 1.41), and reduce work hours (AI/AN ARR = 1.33; 95% CI 1.14, 1.57). Patients of color were more likely than NHWs to stop treatment (NHB ARR = 1.22; 95% CI 1.08, 1.39), borrow money from friends/family (Hispanic ARR = 1.75; 95% CI 1.25, 2.44), skip other medical bills (API/NH ARR = 2.02; 95% CI 1.54, 2.63), and skip non-medical bills (AI/AN ARR = 1.67 95% CI 1.06, 2.63). Non-Hispanic Whites more commonly reported using savings or skipping a vacation to help manage costs. CONCLUSIONS: Racial/ethnic differences exist in employment changes and financial coping among metastatic breast cancer patients, with patients of color experiencing worse consequences. Equity must be a guiding principle in strategies addressing financial burden during cancer care.

Factors Associated with Endocrine Therapy Non-Adherence in Breast Cancer Survivors.

BACKGROUND: For women with hormone receptor positive breast cancer, long-term endocrine therapy (ET) can greatly reduce the risk of recurrence, yet adherence is low- particularly among traditionally underserved populations. METHODS: The Carolina Breast Cancer Study oversampled Black and young women (<50 years of age). Participants answered an ET-specific medication adherence questionnaire assessing reasons for non-adherence. We used principal factor analysis to identify latent factors describing ET non-adherence. We then performed multivariable regression to determine clinical and demographic characteristics associated with each ET non-adherence factor. RESULTS: 1,231 women were included in analysis, 59% reported at least one barrier to ET adherence. We identified three latent factors which we defined as: habit - challenges developing medication-taking behavior; tradeoffs - high perceived side effect burden and medication safety concerns; and resource barriers - challenges related to cost or accessibility. Older age (50+) was associated with less reporting of habit (Adjusted Risk Ratio (aRR) 0.54[95% CI: 0.43-0.69] and resource barriers (aRR 0.66[0.43-0.997]), but was not associated with tradeoff barriers. Medicaid-insured women were more likely than privately-insured to report tradeoff (aRR:1.53 [1.10-2.13]) or resource barriers (aRR:4.43[2.49-6.57]). Black race was associated with increased reporting of all factors (habit: aRR 1.29[1.09-1.53]; tradeoffs: 1.32[1.09-1.60], resources: 1.65[1.18-2.30]). CONCLUSION: Barriers to ET adherence were described by three distinct factors, and strongly associated with sociodemographic characteristics. Barriers to ET adherence appear inadequately addressed for younger, Black, and publicly-insured breast cancer survivors. These findings underscore the importance of developing multi-faceted, patient-centered interventions that address a diverse range of barriers to ET adherence.

Cost-effectiveness of endoscopic ultrasound-directed transgastric ERCP compared with device-assisted and laparoscopic-assisted ERCP in patients with Roux-en-Y anatomy.

BACKGROUND: Roux-en-Y gastric bypass (RYGB) surgery is the second most common weight loss surgery in the United States. Treatment of pancreaticobiliary disease in this patient population is challenging due to the altered anatomy, which limits the use of standard instruments and techniques. Both nonoperative and operative modalities are available to overcome these limitations, including device-assisted (DAE) endoscopic retrograde cholangiopancreatography (ERCP), laparoscopic-assisted (LA) ERCP, and endoscopic ultrasound-directed transgastric ERCP (EDGE). The aim of this study was to compare the cost-effectiveness of ERCP-based modalities for treatment of pancreaticobiliary diseases in post-RYGB patients. METHODS: A decision tree model with a 1-year time horizon was used to analyze the cost-effectiveness of EDGE, DAE-ERCP, and LA-ERCP in post-RYGB patients. Monte Carlo simulation was used to assess a plausible range of incremental cost-effectiveness ratios, net monetary benefit calculations, and a cost-effectiveness acceptability curve. One-way sensitivity analyses and probabilistic sensitivity analyses were also performed to assess how changes in key parameters affected model conclusions. RESULTS: EDGE resulted in the lowest total costs and highest total quality-adjusted life-years (QALY) for a total of $5188/QALY, making it the dominant alternative compared with DAE-ERCP and LA-ERCP. In probabilistic analyses, EDGE was the most cost-effective modality compared with LA-ERCP and DAE-ERCP in 94.4 % and 97.1 % of simulations, respectively. CONCLUSION: EDGE was the most cost-effective modality in post-RYGB anatomy for treatment of pancreaticobiliary diseases compared with DAE-ERCP and LA-ERCP. Sensitivity analysis demonstrated that this conclusion was robust to changes in important model parameters.

Disparities and reverse disparities in HPV vaccination: A systematic review and meta-analysis.

Studies disagree about whether racial and ethnic groups have lower or higher human papillomavirus (HPV) vaccination uptake, an important issue given large disparities in some HPV cancers. We sought to characterize and explain racial and ethnic differences in HPV vaccination. We systematically searched PubMed, CINAHL, Embase, and Web of Science to identify US studies through mid-2017 reporting associations of race and ethnicity with HPV vaccination. We identified 118 studies (n = 3,095,486) published in English that reported HPV vaccine initiation or follow-through in the US from which we could calculate effect sizes. We used random effects meta-analysis to synthesize effect sizes for comparisons of Whites or non-Hispanics to Blacks, Hispanics, Asians, or all minority groups combined. Studies showed no racial or ethnic differences in HPV vaccine initiation overall. However, when restricting to studies using provider-verified vaccination data, minorities were 6.1% [3.3%-8.8%] more likely than Whites to initiate HPV vaccination. Advantages were larger for Hispanics, males, and younger samples (age < 18). In contrast, minorities were 8.6% [5.6%, 11.7%], less likely than Whites to follow-through with the full HPV vaccine series, a disparity present across all participant and study characteristics. More recent studies found larger advantages for racial and ethnic minorities in HPV vaccine initiation and smaller disparities in follow-through. In summary, high-quality studies found racial and ethnic minorities are more likely to initiate but less likely to follow-through with HPV vaccination, a clear finding that self-report studies obscure. Higher HPV vaccine initiation among minorities suggests potential reductions in HPV cancer disparities.

Health Status and Access to Care for the North Carolina Medicaid Gap Population.

BACKGROUND North Carolina remains one of several states that has not expanded Medicaid eligibility criteria to cover all low-income adults, leading to the so-called Medicaid gap, a population ineligible for Medicaid and too poor for premium subsidies through the federal Health Insurance Marketplace. Our objective was to characterize the health care access and health status of the Medicaid gap population in North Carolina.METHODS We combined annual data from the Behavioral Risk Factor Surveillance Survey (2013-2016). Respondents who were uninsured and earning below 100% of the federal poverty guidelines (FPG) were classified as falling within the Medicaid gap and were compared to insured populations below FPG, representing the traditional Medicaid population, and to individuals above the FPG, regardless of insurance status. We reported health care access, receipt of preventive care, and current health status in unadjusted and demographically adjusted models.RESULTS Compared to either traditional Medicaid or above FPG groups, those in the Medicaid gap were 3 times as likely to have no regular source of care and twice as likely to report delaying needed care due to cost. Individuals in the Medicaid gap were more likely than individuals above FPG to report multiple chronic conditions (22% versus 16%) or a functional disability (35% versus 15%), but less likely than the traditional Medicaid population to do so.CONCLUSION While less likely than the traditional Medicaid population to have complex health needs, we found that individuals in the North Carolina Medicaid gap report numerous health care access barriers and lower use of preventive care.

Predictors of Human Papillomavirus Vaccine Follow-Through Among Privately Insured US Patients.

OBJECTIVES: To assess predictors of timely human papillomavirus (HPV) vaccine follow-through among privately insured individuals initiating the 3-dose series. METHODS: Using MarketScan Commercial claims data, we identified 1 332 217 privately insured US individuals aged 9 to 26 years who initiated the bivalent or quadrivalent HPV vaccine series from 2006 to 2014, with follow-up data extending through 2015. The study outcome was receipt of third HPV dose within 12 months of the first, compared by year of initiation. Control variables were age, region, insurance plan type, provider type, and seasonal influenza vaccination. RESULTS: Timely HPV vaccine follow-through fell over time. The trend was especially pronounced for females (from 67% in 2006 to 38% in 2014), but was also present for males (from 36% in 2011 to 33% in 2014). Similar patterns were present when we controlled for patient and provider characteristics or used alternative definitions of follow-through. Other positive predictors of timely follow-through included receipt of flu vaccine in the prior year and receipt of first HPV vaccine dose from an obstetrician/gynecologist. CONCLUSIONS: HPV vaccine follow-through is low and has declined over time.

Oncology navigators' perceptions of cancer-related financial burden and financial assistance resources.

INTRODUCTION: As the cost of cancer treatment continues to rise, many patients are faced with significant emotional and financial burden. Oncology navigators guide patients through many aspects of care and therefore may be especially aware of patients' financial distress. Our objective was to explore navigators' perception of their patients' financial burden and their role in addressing financial needs. MATERIALS AND METHODS: We conducted a real-time online survey of attendees at an oncology navigators' association conference. Participants included lay navigators, oncology nurse navigators, community health workers, and social workers. Questions assessed perceived burden in their patient population and their role in helping navigate patients through financial resources. Answers to open-ended questions are reported using identified themes. RESULTS: Seventy-eight respondents participated in the survey, reporting that on average 75% of their patients experienced some degree of financial toxicity related to their cancer. Only 45% of navigators felt the majority of these patients were able to get some financial assistance, most often through assistance with medical costs (73%), subsidized insurance (36%), or non-medical expenses (31%). Commonly identified barriers for patients obtaining assistance included lack of resources (50%), lack of knowledge about resources (46%), and complex/duplicative paperwork (20%). CONCLUSION: Oncology navigators reported a high burden of financial toxicity among their patients but insufficient knowledge or resources to address this need. This study underscores the importance of improved training and coordination for addressing financial burden, and the need to address community and system-level barriers.

Cost-effectiveness of treatments for heavy menstrual bleeding.

BACKGROUND: Heavy menstrual bleeding affects up to one third of women in the United States, resulting in a reduced quality of life and significant cost to the health care system. Multiple treatment options exist, offering different potential for symptom control at highly variable initial costs, but the relative value of these treatment options is unknown. OBJECTIVE: The objective of the study was to evaluate the relative cost-effectiveness of 4 treatment options for heavy menstrual bleeding: hysterectomy, resectoscopic endometrial ablation, nonresectoscopic endometrial ablation, and the levonorgestrel-releasing intrauterine system. STUDY DESIGN: We formulated a decision tree evaluating private payer costs and quality-adjusted life years over a 5 year time horizon for premenopausal women with heavy menstrual bleeding and no suspected malignancy. For each treatment option, we used probabilities derived from literature review to estimate frequencies of minor complications, major complications, and treatment failure resulting in the need for additional treatments. Treatments were compared in terms of total average costs, quality-adjusted life years, and incremental cost-effectiveness ratios. Probabilistic sensitivity analysis was conducted to understand the range of possible outcomes if model inputs were varied. RESULTS: The levonorgestrel-releasing intrauterine system had superior quality-of-life outcomes to hysterectomy with lower costs. In a probabilistic sensitivity analysis, levonorgestrel-releasing intrauterine system was cost-effective compared with hysterectomy in the majority of scenarios (90%). Both resectoscopic and nonresectoscopic endometrial ablation were associated with reduced costs compared with hysterectomy but resulted in a lower average quality of life. According to standard willingness-to-pay thresholds, resectoscopic endometrial ablation was considered cost effective compared with hysterectomy in 44% of scenarios, and nonresectoscopic endometrial ablation was considered cost effective compared with hysterectomy in 53% of scenarios. CONCLUSION: Comparing all trade-offs associated with 4 possible treatments of heavy menstrual bleeding, the levonorgestrel-releasing intrauterine system was superior to both hysterectomy and endometrial ablation in terms of cost and quality of life. Hysterectomy is associated with a superior quality of life and fewer complications than either type of ablation but at a higher cost. For women who are unwilling or unable to choose the levonorgestrel-releasing intrauterine system as a first-course treatment for heavy menstrual bleeding, consideration of cost, procedure-specific complications, and patient preferences can guide the decision between hysterectomy and ablation.

Promise and Perils of Primary HPV Testing.

Cervical cancer screening has reduced morbidity and mortality in many countries, but efforts to optimize screening modalities and schedules are ongoing. Using data from a randomized trial conducted in British Columbia, Canada, in conjunction with a provincial screening registry, Gottschlich and colleagues demonstrated that the estimated risk for precancerous disease (cervical intraepithelial neoplasia grades 2 or worse) at 8 years following a negative human papillomavirus (HPV) test was similar to the current standard of care (Pap testing after 3 years). The study supports extending screening intervals for those with a negative HPV test beyond currently recommended 5-year intervals. In an ideal world, the resources saved through less frequent routine cervical screening could be redirected to increasing screening uptake and follow-up of abnormalities to improve equity in cervical cancer prevention. However, implementation of extending screening intervals remains less than straightforward in settings with fragmented healthcare systems that lack information systems to support patient call/recall, such as the United States. To achieve the full promise of primary HPV testing, stakeholders at every level must commit to identifying and addressing the diverse spectrum of barriers that undergird existing inequities in care access, appropriately resource implementation strategies, and improve health information systems. See related article by Gottschlich et al., p. 904.

Identifying measures for understanding and addressing county-level disparities in adolescent HPV vaccination coverage in North Carolina.

BACKGROUND: HPV vaccination coverage is characterized by geographic disparities in the US, with national studies finding lower coverage in rural versus nonrural areas. To direct quality improvement efforts in North Carolina, we sought to understand how different rurality measures characterize these disparities. METHODS: We used separate negative binomial regression models to test associations between 5 dichotomized county-level rurality measures and HPV vaccination coverage (≥1 dose) among North Carolina adolescents, ages 11-12 (n=326,345). Rurality measures were derived from: Office of Management and Budget's Metropolitan Statistical Areas, Rural-Urban Continuum Codes, Index of Relative Rurality, US Census Bureau classifications, and North Carolina Rural Center classifications. Models controlled for Social Vulnerability Index (SVI) percentile and rate of pediatricians per county. Vaccination data came from the North Carolina Immunization Registry. RESULTS: HPV vaccination coverage was 29% across North Carolina's 100 counties (range: 13%, 46%). Agreement between rurality measures ranged from 54% to 93% of counties. In adjusted analyses, none of the 5 rurality measures correlated with HPV vaccination coverage, but higher SVI and higher rate of pediatricians were positively associated with coverage (p< 0.01). Exploratory moderation analyses suggested regional variation in the relationship between rurality and coverage, with a positive association in one region, a negative association in one region, and no association in four regions. CONCLUSIONS: County-level rurality measures did not identify disparities in HPV vaccination coverage in North Carolina. IMPACT: Measures related to social vulnerability and access to pediatricians may be better suited for understanding and addressing the state's substantial county-level vaccination disparities.

Adherence to Adjuvant Endocrine Therapy and Survival Among Older Women with Early-Stage Hormone Receptor-Positive Breast Cancer.

BACKGROUND AND OBJECTIVE: Although improving adherence to adjuvant endocrine therapies (AETs) is critical to ensure better patient outcomes, the evidence is still lacking on differences in 5-year AET adherence trajectories. This study aimed to estimate the time trend of adherence by the type of individual AET and the association of adherence to AETs with overall survival among older women with hormone receptor-positive breast cancer. METHODS: This study used the Surveillance, Epidemiology, and End Results-Medicare database 2006-2016. We included women aged ≥ 65 years with newly diagnosed hormone receptor-positive breast cancer and who had initiated AET (anastrozole, letrozole, exemestane, or tamoxifen). Adherence to AETs was defined as the proportion of days covered that was calculated for the follow-up period (5 years). The overall survival time was defined as the time from the date of AET initiation to death. The linear mixed models with repeated measures were used to estimate the changes in adherence to AETs. The Cox proportional hazard model was used to assess the relationships (hazard ratio [HR] and 95% confidence interval [CI]) between adherence to AETs and death. RESULTS: A total of 11,617 patients were included. Anastrozole was the most commonly used (n = 6,908), followed by letrozole (n = 2,586), tamoxifen (n = 1,750), and exemestane (n = 373). The mean (standard deviation) of proportion of days covered for 5 years was 57.4 (34.6), indicating the highest proportion of days covered in the anastrozole group [61.1 (34.1)] and the lowest proportion of days covered in the exemestane group [44.0 (35.1)]. Overall, adherence to AET decreased over the 5-year follow-up period in all AET groups, but the decrease in the tamoxifen group was steeper (42.3% decreased) compared with other AETs. Anastrozole, letrozole, and exemestane groups were associated with a lower risk of death compared with the tamoxifen group (HR = 0.80, 95% CI 0.71-0.89 for anastrozole; HR = 0.82, 95% CI 0.72-0.93 for letrozole; HR = 0.82, 95% CI 0.63-1.07 for exemestane). CONCLUSIONS: Patients who initiated with tamoxifen had a steeper decrease in adherence over the 5 years compared with anastrozole, letrozole, and exemestane groups. Furthermore, higher adherence was associated with a decreased risk of mortality. Physicians should be cognizant of decreasing adherence over time and choose effective treatment options with minimal side-effect profiles to better support adherence by patients with breast cancer.

Adapting a model of cervical carcinogenesis to self-identified Black women to evaluate racial disparities in the United States.

BACKGROUND: Self-identified Black women in the United States have higher cervical cancer incidence and mortality than the general population, but these differences have not been clearly attributed across described cancer care inequities. METHODS: A previously established microsimulation model of cervical cancer was adapted to reflect demographic, screening, and survival data for Black US women and compared with a model reflecting data for all US women. Each model input with stratified data (all-cause mortality, hysterectomy rates, screening frequency, screening modality, follow-up, and cancer survival) was sequentially replaced with Black-race specific data to arrive at a fully specified model reflecting Black women. At each step, we estimated the relative contribution of inputs to observed disparities. RESULTS: Estimated (hysterectomy-adjusted) cervical cancer incidence was 8.6 per 100 000 in the all-race model vs 10.8 per 100 000 in the Black-race model (relative risk [RR] = 1.24, range = 1.23-1.27). Estimated all-race cervical cancer mortality was 2.9 per 100 000 vs 5.5 per 100 000 in the Black-race model (RR = 1.92, range = 1.85-2.00). We found the largest contributors of incidence disparities were follow-up from positive screening results (47.3% of the total disparity) and screening frequency (32.7%). For mortality disparities, the largest contributor was cancer survival differences (70.1%) followed by screening follow-up (12.7%). CONCLUSION: To reduce disparities in cervical cancer incidence and mortality, it is important to understand and address differences in care access and quality across the continuum of care. Focusing on the practices and policies that drive differences in treatment and follow-up from cervical abnormalities may have the highest impact.

Knowledge, Attitudes, and Resources of Frontline Oncology Support Personnel Regarding Financial Burden in Patients With Cancer.

PURPOSE: Financial navigation services support patients with cancer and address the direct and indirect financial burden of cancer diagnosis and treatment. These services are commonly delivered through a variety of frontline oncology support personnel (FOSP) including navigators, social workers, supportive care providers, and other clinic staff, but the perspective of FOSPs is largely absent from current literature on financial burden in oncology. We surveyed a national sample of FOSPs to understand their perspectives on patient financial burden, resource availability, and barriers and facilitators to assisting patients with cancer-related financial burden. METHODS: We used Qualtrics online survey software and recruited participants using multiple professional society and interest group mailing lists. Categorical responses were described using frequencies, distributions of numeric survey responses were described using the median and IQR, and two open-ended survey questions were categorized thematically using a priori themes, allowing additional emergent themes. RESULTS: Two hundred fourteen FOSPs completed this national survey. Respondents reported a high awareness of patient financial burden and felt comfortable speaking to patients about financial concerns. Patient assistance resources were commonly available, but only 15% described resources as sufficient for the observed needs. A substantial portion of respondents reported moral distress related to this lack of resources. CONCLUSION: FOSPs, who already have requisite knowledge and comfort in discussing patient financial needs, are a critical resource for mitigating cancer-related financial burden. Interventions should leverage this resource but prioritize transparency and efficiency to reduce the administrative and emotional toll on the FOSP workforce and reduce the risk of burnout.
