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.

Exploring Disparities in Cancer Screening Among Women With Disabilities [ID 2683490

INTRODUCTION: Unequal access to health care for individuals with disabilities is an increasingly relevant disparity. Further, accessibility to cancer screening remains inadequate. Steele et al. (2017) reported a lower prevalence of women with disabilities undergoing screening for cancer versus women overall in the 2013 National Health Interview Study. The purpose of this study is to compare screening rates for breast, cervical, and colon cancer among female patients with and without disabilities within our health network. METHODS: The study is a retrospective review of patient charts between January 1, 2015 and January 1, 2020. Sample size calculations yielded need for 450 charts to achieve adequate power to detect a 10% reduction in each of the three screening rate analyses. Sample was drawn from electonic medical records and identified female patients ages 21–75 receiving gynecologic care at an eastern Pennsylvania health network. ICD-10-CM codes for disabilities identified patients with cognitive, mobility, speech, or hearing impairments. Statistical analyses included chi-squared goodness-of-fit tests. RESULTS: Cancer screening rates were significantly lower in the sample population. For cervical cancer, patients with disabilities had a 43.3% screening rate versus 66.0% in the general population. For breast cancer, the sample screened at 67.6% versus the general population at 75.0%. For colorectal cancer screening, the sample was at 54.8%, whereas the general population had a 66.0% screening rate (P<.001). CONCLUSION: Understanding the mechanisms behind lower preventive care rates can help to improve health outcomes for this patient population. The future goal is to offer solutions to address disparities in cancer screening.

Culturally Competent Education and Human Papillomavirus Self-Sampling Achieves Healthy People 2030 Cervical Screening Target Among Low-Income Non-Hispanic Black and Hispanic Women

PURPOSE Disparities in cervical cancer screening, incidence, and mortality exist in the United States. Cervical cancer incidence and mortality rates in Texas are 20% and 32% higher, respectively, than national averages. Within Texas, these rates are significantly higher among non-Hispanic (NH) Black and Hispanic women. Cervical cancer screening uptake is lower among NH Black and Hispanic women (72.9% and 75.9%, respectively) compared with White women (85.5%) in Texas. METHODS During March-August 2023, we conducted a pilot study that offered culturally competent education and human papillomavirus (HPV) self-sampling kits to women in two public housing projects in Houston, TX, that have predominantly NH Black or Hispanic residents. Among those eligible for cervical cancer screening, 35% (n = 24) of the NH Black and 34% (n = 16) of the Hispanic women were found to be underscreened per the US Preventive Services Task Force Guideline. We recruited 40 (24 NH Black and 16 Hispanic) eligible women for our study. The study was approved by the MD Anderson institutional review board and registered with ClinicalTrials.gov ( NCT04614155 —March 11, 2020). RESULTS Seventy-five percent of the NH Black and 87% of the Hispanic participants completed the HPV self-sampling procedures per protocol. Samples of 17% NH Black and 12% Hispanic participants showed a performance error. Overall, cervical cancer screening uptake improved from 65% to 91% among NH Black and from 66% to 96% among Hispanic participants. CONCLUSION Culturally competent education and HPV self-sampling resulted in remarkable improvement in cervical cancer screening uptake among underscreened NH Black and Hispanic women residents of Houston public housing projects. Implementing this strategy could significantly reduce cervical cancer incidence and mortality among similar populations in the United States and globally.

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.

Racial and ethnic disparities in prostate cancer screening following the 2018 US Preventive Services Task Force recommendation statement.

In 2018, the United States Preventive Services Task Force promoted shared decision making between healthcare provider and patient for men aged 55 to 69. This study aimed to analyze rates of prostate-specific antigen (PSA) testing across racial and ethnic groups following this new recommendation. A secondary analysis was conducted of the 2020-2021 Behavioral Risk Factor Surveillance System database to assess men aged 55 or older without a history of prostate cancer. We defined four race-ethnicity groups: non-Hispanic Whites (NHWs), non-Hispanic Blacks (NHBs), Hispanics, and Other. The primary outcome was the most recent PSA test (MRT), defined as the respondent's most recent PSA test occurring pre-2018 or post-2018 guidelines. Logistic regression adjusted for covariates including age, socioeconomic status factors, marital status, smoking history, and healthcare access factors. In the age 55 to 69 study sample, NHW men had the greatest proportion of MRT post-2018 guidelines (n = 15,864, 72.5%). NHB men had the lowest percentage of MRT post-2018 guidelines (n = 965, 66.6%). With NHW as referent, the crude odds of the MRT post-2018 guidelines was 0.68 (95% confidence interval (CI) = 0.53-0.90) for NHB. The maximally adjusted odds ratio was 0.78 (0.59-1.02). We found that NHB aged 55 to 69 reported decreased rates of PSA testing after 2018 when compared to NHW. This was demonstrated on crude analysis but not after adjustment. Such findings suggest the influence of social determinants of health on preventative screening for at-risk populations.

Barriers and Facilitators Impacting Lung Cancer Screening Uptake Among Black Veterans: A Qualitative Study.

Racial disparities in lung cancer screening (LCS) are well established. Black Veterans are among those at the highest risk for developing lung cancer but are less likely to complete LCS. We sought to identify barriers and facilitators to LCS uptake among Black Veterans. A qualitative study using semistructured interviews was conducted with 32 Black Veterans to assess for barriers, facilitators, and contextual factors for LCS and strategies to improve screening. Veterans were purposively sampled by age, sex, and LCS participation status (ie, patients who received a low-dose CT [LDCT], patients who contacted the screening program but did not receive an LDCT, and patients who did not connect with the screening program nor receive an LDCT). Interview guides were developed using the Theoretical Domains Framework and Health Belief Model. Data were analyzed using rapid qualitative analysis. Barriers of LCS uptake among Black Veterans include self-reported low LCS knowledge and poor memory, attention, and decision processes associated with the centralized LCS process. Facilitators of LCS uptake among Black Veterans include social/professional role; identity and social influences; perceived susceptibility, threat, and consequences due to smoking status and military or occupational exposures; emotion, behavioral regulation, and intentions; and high trust in providers. Environmental context and resources (eg, transportation) and race and racism serve as contextual factors that did not emerge as having a major impact on LCS uptake. Strategies to improve LCS uptake included increased social messaging surrounding LCS, various forms of information dissemination, LCS reminders, balanced and repeated shared decision-making discussions, and streamlined referrals. We identified addressable barriers and facilitators for LCS uptake among Black Veterans that can help focus efforts to improve disparities in screening. Future studies should explore provider perspectives and test interventions to improve equity in LCS.

Nativity Disparities in Colorectal Cancer Screening Among Hispanics in the United States.

Hispanics in the United States (U.S.) have previously exhibited lower guideline-concordant colorectal cancer (CRC) screening uptake than non-Hispanic (NH) Whites, with disparities accentuated in foreign-born Hispanics, however it is unclear whether nativity-related CRC screening disparities have changed in the last two decades and whether these disparities are attenuated after adjusting for socioeconomic and demographic characteristics. We evaluated CRC screening adherence in foreign- and U.S.-born Hispanics compared to U.S.-born NH Whites. We used 2019 National Health Interview Survey data to compare the prevalence of up-to-date CRC screening per the 2019 U.S. Preventive Services Task Force recommendations among Hispanic nativity subgroups (i.e., foreign- and U.S.-born) and U.S.-born NH Whites using unadjusted and adjusted weighted log-linked binomial regression. Foreign- and U.S.-born Hispanics had a significantly lower unadjusted prevalence of up-to-date screening than U.S.-born NH Whites (47.18% and 64.18% versus 70.70%; p < 0.0001 and p = 0.0109, respectively). After adjusting for socioeconomic and demographic differences, the prevalence of up-to-date screening was lower in foreign-born Hispanics compared to U.S.-born NH Whites [adjusted prevalence ratio 0.80 (95% confidence interval 0.70-0.91)]; however, no statistically significant difference was observed between U.S.-born Hispanics and NH Whites. Our results suggest a low screening uptake in foreign-born Hispanics independent of socioeconomic and demographic differences. Future interventions should target foreign-born Hispanics to address disparities and promote early detection and prevention of CRC regardless of socioeconomic factors.

206 Cervical Cancer Disparities: Knowledge, Screening and Willingness to adopt testing modalities among Hispanic/Latinx Women in Lake County, Indiana

OBJECTIVES/GOALS: There are notable disparities in cervical cancer screening. Theobjective of this study was to examine knowledge, screening practices, attitudes towards cervical cancer screening, and willingness to adopt screening innovations such as self-sampling and HPV rapid testing for cervical cancer among Hispanic women in Lake County, Indiana. METHODS/STUDY POPULATION: This mixed-methods study encompassed an online cross-sectional survey (n=231) and in-depth interviews (n=9) of individuals with a cervix aged 21-65 residing in Lake County, Indiana. Outcome variables focused on cervical cancer knowledge, willingness to adopt self-sampling, and willingness to adopt HPV rapid testing. Descriptive statistics included frequencies and percentages. A cervical cancer knowledge score was computed from 7 questions. Scores below the mean 3.62 were labeled ‘low’ while higher scores were ‘high’. We also examined associations between demographic and outcome variables. Quantitative analysis was conducted using SPSS software. Qualitative analysis was conducted using NVIVO software to thematically analyze interviews using deductive and inductive coding techniques. RESULTS/ANTICIPATED RESULTS: Majority of participants identified as Hispanic (58%), aged 31 or older (58%). While 80.5% reported being screened for cervical cancer, only 44.6% demonstrated ‘high' cervical cancer knowledge. 89.6% felt screening is important as emphasized in qualitative findings for its preventive value. Over half were willing to take their vaginal swab in clinic (55.8%) and at home (51.9%). However, among the Hispanic/Latinx groups reluctance to adopt self-sampling was notable (56.7% in clinic and 62.7% at home). Qualitative analysis revealed concerns about test accuracy. Willingness to use a hypothetical HPV rapid had higher acceptance (69.7%), with 52.2% in the Hispanic/Latinx group. Qualitative findings highlight benefits like increased screening access, comfort, and convenience offered by an HPV rapid test. DISCUSSION/SIGNIFICANCE: Hispanic/Latinx women in the sample were less willing to adopt cervical cancer screening methods such as self-sampling and rapid testing compared to non-Hispanic whites. Despite being considered beneficial for testing among vulnerable populations, our study found limited acceptance from these populations for various reasons.

Relationships Among Determinants of Health, Cancer Screening Participation, and Sexual Minority Identity: A Systematic Review.

Purpose: To address cancer screening disparities and reduce cancer risk among sexual minority (SM) groups, this review identifies individual, interpersonal, and community/societal determinants of cancer screening (non)participation among differing SM identities. Methods: Seven scientific databases were searched. Inclusion criteria were as follows: (1) used quantitative methods; (2) English language; (3) cancer screening focus; and (4) at least one SM group identified. Articles were excluded if: (1) analysis was not disaggregated by SM identity (n = 29) and (2) quantitative analysis excluded determinants of cancer screening (n = 19). The Sexual and Gender Minority Health Disparities Research Framework guided literature synthesis. Results: Twelve studies addressed cervical (n = 4), breast (n = 3), breast/cervical (n = 3), or multiple cancers (n = 2). Other cancers were excluded due to inclusion/exclusion criteria. The total sample was 20,622 (mean 1525), including lesbian (n = 13,409), bisexual (n = 4442), gay (n = 1386), mostly heterosexual (n = 1302), and queer (n = 83) identities. Studies analyzing individual-level determinants (n = 8) found that socioeconomic status affected cervical, but not breast, cancer screening among lesbian and bisexual participants (n = 2). At the interpersonal level (n = 7), provider-patient relationship was a determinant of cervical cancer screening among lesbian participants (n = 4); a relationship not studied for other groups. Studies analyzing community/societal determinants (n = 5) found that rurality potentially affected cervical cancer screening among lesbian, but not bisexual people (n = 3). Conclusions: This review identified socioeconomic status, provider-patient relationship, and rurality as determinants affecting cancer screening among SM people. While literature addresses diverse SM groups, inclusion/exclusion criteria identified studies addressing cisgender women. Addressing disparities in the identified determinants of cervical cancer screening may improve participation among SM women. Further research is needed to understand determinants of cancer screening unique to other SM groups.

Examining cancer screening disparities by race/ethnicity and insurance groups: A comparison of 2008 and 2018 National Health Interview Survey (NHIS) data in the United States.

Pervasive differences in cancer screening among race/ethnicity and insurance groups presents a challenge to achieving equitable healthcare access and health outcomes. However, the change in the magnitude of cancer screening disparities over time has not been thoroughly examined using recent public health survey data. A retrospective cross-sectional analysis of the 2008 and 2018 National Health Interview Survey (NHIS) database focused on breast, cervical, and colorectal cancer screening rates among race/ethnicity and insurance groups. Multivariable logistic regression models were used to assess the relationship between cancer screening rates, race/ethnicity, and insurance coverage, and to quantify the changes in disparities in 2008 and 2018, adjusting for potential confounders. Colorectal cancer screening rates increased for all groups, but cervical and mammogram rates remained stagnant for specific groups. Non-Hispanic Asians continued to report consistently lower odds of receiving cervical tests (OR: 0.42, 95% CI: 0.32-0.55, p<0.001) and colorectal cancer screening (OR: 0.55, 95% CI: 0.42-0.72, p<0.001) compared to non-Hispanic Whites in 2018, despite significant improvements since 2008. Non-Hispanic Blacks continued to report higher odds of recent cervical cancer screening (OR: 1.98, 95% CI: 1.47-2.68, p<0.001) and mammograms (OR: 1.32, 95% CI: 1.02-1.71, p<0.05) than non-Hispanic Whites in 2018, consistent with higher odds observed in 2008. Hispanic individuals reported improved colorectal cancer screening over time, with no significant difference compared to non-Hispanics Whites in 2018, despite reporting lower odds in 2008. The uninsured status was associated with significantly lower odds of cancer screening than private insurance for all three cancers in 2008 and 2018. Despite an overall increase in breast and colorectal cancer screening rates between 2008 and 2018, persistent racial/ethnic and insurance disparities exist among race/ethnicity and insurance groups. These findings highlight the importance of addressing underlying factors contributing to disparities among underserved populations and developing corresponding interventions.

Disparities across the continuum of lung cancer care: a review of recent literature.

Lung cancer remains the leading cause of cancer mortality worldwide. Health disparities have long been noted in lung cancer incidence and survival and persist across the continuum of care. Understanding the gaps in care that arise from disparities in lung cancer risk, screening, treatment, and survivorship are essential to guiding efforts to achieve equitable care. Recent literature continues to show that Black people, women, and people who experience socioeconomic disadvantage or live in rural areas experience disparities throughout the spectrum of lung cancer care. Contributing factors include structural racism, lower education level and health literacy, insurance type, healthcare facility accessibility, inhaled carcinogen exposure, and unmet social needs. Promising strategies to improve lung cancer care equity include policy to reduce exposure to tobacco smoke and harmful pollutants, more inclusive lung cancer screening eligibility criteria, improved access and patient navigation in lung cancer screening, diagnosis and treatment, more deliberate offering of appropriate surgical and medical treatments, and improved availability of survivorship and palliative care. Given ongoing disparities in lung cancer care, research to determine best practices for narrowing these gaps and to guide policy change are an essential focus of future lung cancer research.

Multilevel approaches to address disparities in lung cancer screening: a study protocol

BackgroundLow-dose computed tomography (lung cancer screening) can reduce lung cancer-specific mortality by 20–24%. Based on this evidence, the United States Preventive Services Task Force recommends annual lung cancer screening for asymptomatic high-risk individuals. Despite this recommendation, utilization is low (3–20%). Lung cancer screening may be particularly beneficial for African American patients because they are more likely to have advanced disease, lower survival, and lower screening rates compared to White individuals. Evidence points to multilevel approaches that simultaneously address multiple determinants to increase screening rates and decrease lung cancer burden in minoritized populations. This study will test the effects of provider- and patient-level strategies for promoting equitable lung cancer screening utilization.MethodsGuided by the Health Disparities Research Framework and the Practical, Robust Implementation and Sustainability Model, we will conduct a quasi-experimental study with four primary care clinics within a large health system (MedStar Health). Individuals eligible for lung cancer screening, defined as 50–80 years old, ≥ 20 pack-years, currently smoking, or quit < 15 years, no history of lung cancer, who have an appointment scheduled with their provider, and who are non-adherent to screening will be identified via the EHR, contacted, and enrolled (N = 184 for implementation clinics, N = 184 for comparison clinics; total N = 368). Provider participants will include those practicing at the partner clinics (N = 26). To increase provider-prompted discussions about lung screening, an electronic health record (EHR) clinician reminder will be sent to providers prior to scheduled visits with the screening-eligible participants. To increase patient-level knowledge and patient activation about screening, an inreach specialist will conduct a pre-visit phone-based educational session with participants. Patient participants will be assessed at baseline and 1-week post-visit to measure provider-patient discussion, screening intentions, and knowledge. Screening referrals and screening completion rates will be assessed via the EHR at 6 months. We will use mixed methods and multilevel assessments of patients and providers to evaluate the implementation outcomes (adoption, feasibility, acceptability, and fidelity).DiscussionThe study will inform future work designed to measure the independent and overlapping contributions of the multilevel implementation strategies to advance equity in lung screening rates.Trial registrationClinicalTrials.gov, NCT04675476.

Racial and ethnic differences in the receipt of metabolic syndrome risk factor screening and treatment among individuals with prostate cancer treated with androgen deprivation therapy.

29 Background: Racial and ethnic health disparities in prostate cancer screening, and treatment constitute the largest of all cancer disparities. Androgen deprivation therapy (ADT) is widely used in the treatment of localized or metastatic prostate cancer. However, ADT is associated with toxic cardiovascular and metabolic adverse events that may occur as early as 6 months of therapy initiation. This study aimed to assess racial/ethnic differences and longitudinal changes in metabolic syndrome risk factor (MSRF) screening/treatment among patients with prostate cancer treated with ADT at a university-affiliated comprehensive cancer center in the southwestern U.S. between 2010-2021. We also aimed to identify patient and healthcare provider factors that influence MSRF screening among study sample. Methods: A retrospective observational cohort study of 803 patients treated with ADT for at least six months at the cancer center was conducted. Patients were followed three months pre- to 12 months post-ADT initiation to evaluate MSRF screening/treatment. Determination of MSRF screening was based on primary care provider referral for MSRF screening/treatment or receipt of blood glucose, lipid profile, and blood pressure screening within six months post-treatment with ADT. Patients were considered treated for MSRF if they were started or continued therapy (within six months of ADT initiation) with science advisory guideline recommended treatments. Results: Guideline-concordant MSRF screening rate approached 23.5%; MSRF treatment rate was 76.9%. A higher treatment rate in MSRF treatment was found for NHW compared to Hispanic men ( p=0.02). We found a significant difference in the proportion of patients receiving MSRF screening across all racial/ethnic groups ( p=0.03). MSRF screening rates from 13.9% to 35.6% were observed over the 10-year data collection period. Patients with dyslipidemia at baseline had higher odds of having MSRF screening than patients without dyslipidemia ( p&lt;0.0001). Oncologists with &gt;20 years of experience had higher odds of providing MSRF screening compared with &lt;10 years of experience ( p=0.006). Conclusions: Minority populations had significantly lower odds of having MSRF screening than NHW patients after adjusting for clinical and socio-economic variables. Closer clinical attention and education, as well as the development and implementation of innovative practice tools and interventions to optimize MSRF screening and treatment are warranted to mitigate the harmful adverse effects of ADT in patients with prostate cancer.

Biomarkers as a tool to reduce disparities in lung cancer screening and detection.

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.

Colon cancer screening disparities among limited English proficient patients during implementation of patient navigation services.

17 Background: Age-appropriate colon cancer screening has long demonstrated effectiveness in reducing colon cancer incidence and mortality. However, despite a gradual rise in compliance with colon cancer screening, significant disparities remain, particularly among patients with limited English proficiency (LEP). Multitarget stool DNA (MT-sDNA) testing (Exact Sciences, Madison, WI) has been available over the past decade in the United States as a lower-cost and non-invasive option for screening. In 2019, Exact Sciences began to offer patient navigation services comprising outbound phone, text, and e-mail reminders, and inbound phone support (&gt;200 languages) with all MT-sDNA orders. In this study, we aimed to evaluate the disparity in successful MT-sDNA testing between LEP and EP patients in a time frame when patient navigation services were active. Methods: We performed a retrospective cohort study of patients 45-75 years old enrolled in the primary care setting of our institution who received an order for MT-sDNA screening during a period in which patient navigation services began to be offered. A multi-state Cox model was constructed with time to MT-sDNA or other CRC screening predicted by English proficiency accounting for age and gender. Wald tests were used to test the association of CRC screening completion and English proficiency. Rates of completion of MT-sDNA screening and other CRC screening following MT-sDNA test ordering were calculated using the Kaplan-Meier method. Results: Of the 5016 patients evaluated and referred for multitarget stool DNA testing from May 1st, 2021, and May 1st, 2022, 154 patients were of LEP, and 4862 were English proficient (EP). At 180 days following a MT-sDNA test order the rate of completion for the LEP patients was 50.2% (95% CI: 42.8-58.7%) versus 70.3% (95% 69.1-71.6%) for EP individuals (p=0.001). A small portion of individuals also completed another type of CRC screen, 3.3% for LEP and 2.5% for EP (p=0.99). Conclusions: This study is consistent with the existing research demonstrating LEP as a significant demographic group linked with decreased participation in cancer screening. Our findings indicated that despite the availability of patient navigation services, individuals with LEP were still less likely to complete an MT-sDNA test successfully when compared to those with EP.

Rural-Urban Disparities in Colorectal Cancer Screening, Diagnosis, Treatment, and Survivorship Care: A Systematic Review and Meta-Analysis.

Rural residents have a higher prevalence of colorectal cancer (CRC) mortality compared to urban individuals. Policies have been aimed at improving access to CRC screening to reduce these outcomes. However, little attention has been paid to other determinants of CRC-related outcomes, such as stage at diagnosis, treatment, or survivorship care. The main objective of this analysis was to evaluate literature describing differences in CRC screening, stage at diagnosis, treatment, and survivorship care between rural and urban individuals. We conducted a systematic review of electronic databases using a combination of MeSH and free-text search terms related to CRC screening, stage at diagnosis, treatment, survivorship care, and rurality. We identified 921 studies, of which 39 were included. We assessed methodological quality using the ROBINS-E tool and summarized findings descriptively. A meta-analysis was performed of studies evaluating CRC screening using a random-effects model. Seventeen studies reported disparities between urban and rural populations in CRC screening, 12 on treatment disparities, and 8 on staging disparities. We found that rural individuals were significantly less likely to report any type of screening at any time period (pooled odds ratio = 0.81, 95% CI, 0.76-0.86). Results were inconclusive for disparities in staging at diagnosis and treatment. One study reported a lower likelihood of use of CRC survivorship care for rural individuals compared to urban individuals. There remains an urgent need to evaluate and address CRC disparities in rural areas. Investigators should focus future work on assessing the quality of staging at diagnosis, treatment, and survivorship care in rural areas.

Integrating HPV self-collect into primary care to address cervical cancer screening disparities

Human papillomavirus (HPV) self-collect shows promise to increase cervical cancer screening rates in underscreened populations, such as Somali patients, but little is known about how to integrate such an approach in primary care. In this study, primary care providers and staff who provide primary care services to Somali women were asked for their views on integrating HPV self-collect into routine care to address cervical cancer screening disparities. Thirty primary care providers and staff participated in semi-structured interviews exploring their views on HPV self-collect and their anticipated needs or barriers to implementing this approach into the clinic generally and with specific patient populations, such as Somali women. A thematic analysis using the constructivist version of grounded theory was undertaken. Providers and staff anticipate positive patient reaction to the option of HPV self-collect, and were interested in using this approach both for Somali patients and for all patients in general. HPV self-collect was viewed as straightforward to integrate into existing clinic workflows. Providers largely lacked awareness of the evidence supporting primary HPV testing and HPV self-collect specifically, sharing concerns about effectiveness of self-collect and the lack of a physical exam. Providers felt clinic-wide staff education and patient education, along with strategies to address disparities, such as cultural and linguistic tailoring would be needed for successful implementation. Integrating HPV self-collect as an option in the cervical cancer screening process in a primary care clinical encounter offers considerable opportunity to address health disparities and may benefit all patients.

Characteristics and Barriers of Emergency Department Patients Overdue for Cancer Screening.

People without reliable access to healthcare are more likely to be diagnosed with late-stage cancer that could have been treated more effectively if diagnosed earlier. Emergency departments (ED) may be a novel place for cancer screening education for underserved patients. In this study we sought to determine patient characteristics and barriers to cancer screening for those patients who presented to a large, academic safety-net ED and were overdue for breast, cervical, and colorectal cancer screening since the coronavirus 2019 (COVID-19) pandemic. Adult ED patients eligible for at least one cancer screening based on US Preventive Serivces Task Force guidelines completed a web-based survey. We examined the association of demographic characteristics and having a personal physician with being overdue on screening using chi-square or the Fisher exact test for categorical variables and t-tests for continuous variables. Of 221 participants, 144 were eligible for colorectal, 96 for cervical, and 55 for breast cancer screening. Of eligible patients, 46% (25/55) were overdue for breast cancer screening, 43% (62/144) for colorectal, and 40% (38/96) for cervical cancer screening. There were no significant characteristics associated with breast cancer screening. Being overdue for cervical cancer screening was significantly more likely for patients who were of Asian race (P = 0.02), had less than a high school diploma (P = 0.01), and were without a routine checkup within the prior five years (P = 0.01). Overdue for colorectal cancer screening was associated with patients not having insurance (P = 0.04), being in their 40s (P = 0.03), being Hispanic (P = 0.01), and not having a primary care physician (P=0.01). Of 97 patients overdue for at least one screening, the most common barriers were cost (37%), lack of time (37%), and lack of knowledge of screening recommendations (34%). Only 8.3% reported that the COVID-19 pandemic delayed their screening. The ED may be a novel setting to target patients for cancer screening education. Future work that refers patients to free screening programs and primary care physicians may help improve disparities in cancer screening and cancer mortality rates for underserved populations.
