Lung Cancer Survival Trends in the Veterans Health Administration

INTRODUCTION

Lung cancer survival is improving in the United States. We investigated whether there was a similar trend within the Veterans Health Administration (VHA), the largest integrated healthcare system in the United States.

MATERIALS AND METHODS

Data from the Veterans Affairs Central Cancer Registry were analyzed for temporal survival trends using Kaplan-Meier estimates and linear regression.

RESULTS

A total number of 54,922 Veterans were identified with lung cancer diagnosed from 2010 to 2017. Histologies were classified as non-small-cell lung cancer (NSCLC) (64.2%), small cell lung cancer (SCLC) (12.9%), and 'other' (22.9%). The proportion with stage I increased from 18.1% to 30.4%, while stage IV decreased from 38.9% to 34.6% (both P < .001). The 3-year overall survival (OS) improved for stage I (58.6% to 68.4%, P < .001), stage II (35.5% to 48.4%, P < .001), stage III (18.7% to 29.4%, P < .001), and stage IV (3.4% to 7.8%, P < .001). For NSCLC, the median OS increased from 12 to 21 months (P < .001), and the 3-year OS increased from 24.1% to 38.3% (P < .001). For SCLC, the median OS remained unchanged (8 to 9 months, P = .10), while the 3-year OS increased from 9.1% to 12.3% (P = .014). Compared to White Veterans, Black Veterans with NSCLC had similar OS (P = .81), and those with SCLC had higher OS (P = .003).

CONCLUSION

Lung cancer survival is improving within the VHA. Compared to White Veterans, Black Veterans had similar or higher survival rates. The observed racial equity in outcomes within a geographically and socioeconomically diverse population warrants further investigation to better understand and replicate this achievement in other healthcare systems.

Breast Cancer Screening in the Intermediate-Risk Population: Falling Through the Cracks?

Breast cancer screening guidelines vary for women at intermediate risk (15%-20% lifetime risk) for developing breast cancer across jurisdictions. Currently available risk assessment models have differing strengths and weaknesses, creating difficulty and ambiguity in selecting the most appropriate model to utilize. Clarifying which model to utilize in individual circumstances may help determine the best screening guidelines to use for each individual.

Resident Attitudes and Experiences with a Novel Radiology-based Transgender Curriculum: A Qualitative Study

RATIONALE AND OBJECTIVES

Transgender persons often experience healthcare disparities due to lack of provider knowledge. With increasing gender diversity awareness and prevalence of gender-affirming care, radiologists-in-training need to be aware of the unique health considerations for this patient population. Radiology residents have limited exposure to dedicated teaching on transgender medical care and imaging during training. Development and implementation of a radiology-based transgender curriculum can help close this gap in radiology residency education. The aim of this study was to explore radiology resident attitudes and experiences with a novel radiology-based transgender curriculum, guided by the conceptual framework of reflective practice.

MATERIALS AND METHODS

A qualitative approach was employed using semi-structured interviews to explore resident perspectives of a curriculum covering transgender patient care and imaging over 4 monthly sessions. Ten residents at the University of Cincinnati radiology residency participated in interviews consisting of open-ended questions. Interviews were audiotaped, transcribed, and thematic analysis was conducted across all responses.

RESULTS

Four themes emerged through the existing framework: 1) impactful/memorable aspects; things learned; increased awareness; and suggestions/feedback. Prominent subthemes included patient panel and stories, physician experts sharing knowledge and experiences, link to radiology and imaging, novel concept, gender-affirming surgeries and anatomy, appropriate radiology reporting, and patient interactions.

CONCLUSION

Radiology residents found the curriculum to be an effective novel educational experience that was previously unaddressed during their training. This imaging-based curriculum can be further adapted and implemented in a variety of radiology curricular settings.

Fostering Patient-Centered Equitable Care in Radiology: AJR Expert Panel Narrative Review

Patient-centered care (PCC) and equity are two of the six core domains of quality health care, according to the Institute of Medicine. Exceptional imaging care requires radiology practices to provide patient-centered (i.e., respectful and responsive to individual patient preferences, needs, and values) and equitable (i.e., does not vary in quality on the basis of gender, ethnicity, geographic location, or socioeconomic status) care. Specific barriers that prevent the delivery of patient-centered equitable care include information gaps, breaches of trust, organizational medical culture, and financial incentives. Information gaps limit practitioners in understanding the lived experience of patients. Breaches of trust prevent patients from seeking needed medical care. Organizational medical cultures may not be centered around patient experiences. Financial incentives can impede practitioners' ability to spend the time and resources required to meet patient goals and needs. Intentional approaches that integrate core principles in both PCC and health equity are required to deliver high-quality patient-centered imaging care for diverse patient populations. The purpose of this AJR Expert Panel Narrative Review is to review the origins of the PCC movement in radiology, characterize connections between the PCC and health equity movements, and describe concrete examples of ways to foster patient-centered equitable care in radiology.

The Association of Organizational Readiness With Lung Cancer Screening Utilization

INTRODUCTION

Lung cancer screening is widely underutilized. Organizational factors, such as readiness for change and belief in the value of change (change valence), may contribute to underutilization. The aim of this study was to evaluate the association between healthcare organizations' preparedness and lung cancer screening utilization.

METHODS

Investigators cross-sectionally surveyed clinicians, staff, and leaders at10 Veterans Affairs from November 2018 to February 2021 to assess organizational readiness to implement change. In 2022, investigators used simple and multivariable linear regression to evaluate the associations between facility-level organizational readiness to implement change and change valence with lung cancer screening utilization. Organizational readiness to implement change and change valence were calculated from individual surveys. The primary outcome was the proportion of eligible Veterans screened using low-dose computed tomography. Secondary analyses assessed scores by healthcare role.

RESULTS

The overall response rate was 27.4% (n=1,049), with 956 complete surveys analyzed: median age of 49 years, 70.3% female, 67.6% White, 34.6% clinicians, 61.1% staff, and 4.3% leaders. For each 1-point increase in median organizational readiness to implement change and change valence, there was an associated 8.4-percentage point (95% CI=0.2, 16.6) and a 6.3-percentage point increase in utilization (95% CI= -3.9, 16.5), respectively. Higher clinician and staff median scores were associated with increased utilization, whereas leader scores were associated with decreased utilization after adjusting for other roles.

CONCLUSIONS

Healthcare organizations with higher readiness and change valence utilized more lung cancer screening. These results are hypothesis generating. Future interventions to increase organizations' preparedness, especially among clinicians and staff, may increase lung cancer screening utilization.

Social Determinants of Health in Imaging-based Cancer Screening: A Case-based Primer with Strategies for Care Improvement

Health disparities, preventable differences in the burden of disease and disease outcomes often experienced by socially disadvantaged populations, can be found in nearly all areas of radiology, including emergency radiology, neuroradiology, nuclear medicine, image-guided interventions, and imaging-based cancer screening. Disparities in imaging-based cancer screening are especially noteworthy given the far-reaching population health impact. The social determinants of health (SDoH) play an important role in disparities in cancer screening and outcomes. Through improved understanding of how SDoH can drive differences in health outcomes in radiology, radiologists can effectively provide patient-centered, high-quality, and equitable care. Radiologists and radiology practices can become active partners in efforts to assist patients along their imaging journey and overcome existing barriers to equitable cancer screening care for traditionally marginalized populations. As radiology exists at the intersection of diagnostic imaging, image-guided diagnostic intervention, and image-guided treatment, radiologists are uniquely positioned to design these strategies. Cost-effective and socially conscious strategies that address barriers to equitable care can improve both public health and equitable health outcomes. Potential strategies include championing supportive health policy, reducing out-of-pocket costs, increasing price transparency, improving education and outreach efforts, ensuring that appropriate language translation services are available, providing individualized assistance with appointment scheduling, and offering transportation assistance and childcare. ©RSNA, 2023 Quiz questions for this article are available in the supplemental material.

Beyond the Binary: Moving the Radiology Workforce Toward Gender Inclusion, From the AJR Special Series on DEI

Gender representation in radiology has traditionally been evaluated and reported through binary models, accompanied by advocacy efforts focused on increasing the number of women in radiology. A paucity of data exists to understand the entire gender composition of the radiology workforce, including representation of people who are transgender and gender diverse. Further, little information exists on how to provide a supportive work environment for radiologists and support staff who identify as belonging to an underrepresented gender minority group. Intentional efforts to comprehensively understand the gender representation of the radiology workforce can help to establish a diverse workforce that is more representative of the patient populations that we serve, while promoting high-quality inclusive health care. Moving beyond gender binary thought and practices can help foster a culture of inclusion and belonging in radiology. This article provides practical steps that radiology practices can take to understand and support gender diversity beyond the binary in the radiology workforce, including providing definitions and inclusive language, understanding limitations of historical methods of gender data collection in radiology and relevant published literature, establishing best practices for future data collection, and developing a strategic vision with action items to create a more inclusive work environment.

Prevalence of Diversity Statements and Disability Inclusion Among Radiology Residency Program Websites

INTRODUCTION

Radiology has widely acknowledged the need to improve inclusion of racial, ethnic, gender, and sexual minorities, with recent discourse also underscoring the importance of disability diversity and inclusion efforts. Yet studies have shown a paucity of diversity among radiology residents, despite increasing efforts to foster diversity and inclusion. Thus, the purpose of this study is to assess radiology residency program websites' diversity statements for inclusion of race and ethnicity, gender, sexual orientation, and disability as commonly underrepresented groups.

METHODS

A cross-sectional, observational study of websites of all diagnostic radiology programs in the Electronic Residency Application Service directory was conducted. Program websites that met inclusion criteria were audited for presence of a diversity statement; if the statement was specific to the residency program, radiology department, or institution; and if it was presented or linked on the program or department website. All statements were evaluated for the inclusion of four diversity categories: race or ethnicity, gender, sexual orientation, and disability.

RESULTS

One hundred ninety-two radiology residencies were identified using Electronic Residency Application Service. Programs with missing or malfunctioning hyperlinks (n = 33) or required logins (n = 1) were excluded. One hundred fifty-eight websites met inclusion criteria for analysis. Two-thirds (n = 103; 65.1%) had a diversity statement within their residency, department, or institution, with only 28 (18%) having residency program-specific statements and 22 (14%) having department-specific statements. Of the websites with diversity statements, inclusion of gender diversity was most frequent (43.0%), followed by race or ethnicity (39.9%), sexual orientation (32.9%), and disability (25.3%). Race or ethnicity was most included in institution-level diversity statements.

CONCLUSIONS

Less than 20% of radiology residency websites include a diversity statement, and disability is the least-included category among the diversity statements. As radiology continues to lead diversity and inclusion efforts in health care, a more comprehensive approach with equitable representation of different groups, including those with disabilities, would foster a broader sense of belonging. This comprehensive approach can help to overcome systemic barriers and bridge gaps in disability representation.

Rural barriers and facilitators of lung cancer screening program implementation in the veterans health administration: a qualitative study

Introduction

To assess healthcare professionals' perceptions of rural barriers and facilitators of lung cancer screening program implementation in a Veterans Health Administration (VHA) setting through a series of one-on-one interviews with healthcare team members.

Methods

Based on measures developed using Reach Effectiveness Adoption Implementation Maintenance (RE-AIM), we conducted a cross-sectional qualitative study consisting of one-on-one semi-structured telephone interviews with VHA healthcare team members at 10 Veterans Affairs medical centers (VAMCs) between December 2020 and September 2021. An iterative inductive and deductive approach was used for qualitative analysis of interview data, resulting in the development of a conceptual model to depict rural barriers and facilitators of lung cancer screening program implementation.

Results

A total of 30 interviews were completed among staff, providers, and lung cancer screening program directors and a conceptual model of rural barriers and facilitators of lung cancer screening program implementation was developed. Major themes were categorized within institutional and patient environments. Within the institutional environment, participants identified systems-level (patient communication, resource availability, workload), provider-level (attitudes and beliefs, knowledge, skills and capabilities), and external (regional and national networks, incentives) barriers to and facilitators of lung cancer screening program implementation. Within the patient environment, participants revealed patient-level (modifiable vulnerabilities) barriers and facilitators as well as ecological modifiers (community) that influence screening behavior.

Discussion

Understanding rural barriers to and facilitators of lung cancer screening program implementation as perceived by healthcare team members points to opportunities and approaches for improving lung cancer screening reach, implementation and effectiveness in VHA rural settings.

Canadian radiology workforce demographics: Results from a national survey

Rationale and objective

Demographic data collected about Canadian radiologists and trainees has been limited primarily to binary gender and geographic location. The purpose of this study was to investigate: (1) demographic characteristics of Canadian radiologists and trainees; (2) types of diversity important to radiologists; (3) relationship of radiologist demographics to practice characteristics; and (4) relationship of radiologist demographics to years in practice, (YIP).

Materials and methods

French and English surveys were distributed via email through radiology associations and social media. Frequency counts of demographic variables were calculated, and chi-square and Fisher's Exact tests were performed to explore the relationships between demographic characteristics and role.

Results

611 individuals responded to the survey. 573 respondents were included in the analysis. 454 (78.8%) were practicing radiologists and 119 (20.7%) were residents/fellows. Half identified as women (50.4%). English was the primary language for most respondents. There was an association between role and sexual orientation (p = 0.02), visible minority (χ2 = 4.79, p < 0.05), religion (χ2 = 4.11, p < 0.05), and having children (χ2 = 136.65, p < 0.05). For radiologists, being a visible minority (χ2 = 11.59, p < 0.05) and age (χ2 = 56.3, p < 0.05) were associated with academic rank while gender (χ2 = 3.83, p < 0.05) and age (χ2 = 13.74, p < 0.05) were related to part-/full-time status. Less women, visible minorities, and women with children had been in practice for long.

Discussion

This study represents a comprehensive analysis of Canadian radiology demographics. Results suggest there is increasing diversity among trainees; however, significant demographic underrepresentation compared to the diversity of Canada exists.

APDR Healthcare Disparities Curriculum Pilot: Helping Trainees Meet More Than a Milestone

RATIONALE AND OBJECTIVES

In order to help program directors satisfy the Accreditation Council for Graduate Medical Education common program requirement for health care disparities (HCD) education, a comprehensive web-based curriculum on HCDs in Radiology was developed. The curriculum was designed to educate trainees about existing HCDs, stimulate discussion, and spur research about HCDs in radiology. The curriculum was piloted to assess its educational value and feasibility.

MATERIAL AND METHODS

A comprehensive curriculum comprised of four modules (1) Introduction to HCDs in Radiology, (2) Types of HCDs in Radiology, (3) Actions to Address HCDs in Radiology, and (4) Cultural Competency was created and housed on the Associate of Program Directors in Radiology website. Various educational media including recorded lectures or PowerPoint presentations, small group discussions, and journal clubs were employed. A pilot program was initiated to evaluate the benefits of this curriculum for resident education and consisted of a pre- and post-curriculum test for trainees, an experience survey for trainees, and a pre- and post-administration survey for facilitators.

RESULTS

Forty-seven radiology residency programs participated in the pilot of the HCD curriculum. Of those facilitating the curriculum, 83% indicated lack of standardized curriculum as a perceived barrier to implementing a HCD curriculum at their program on the pre-survey. Trainee knowledge scores increased from 65% (pre) to 67% (post) (p = 0.05). Following curriculum participation, residents indicated an increase in adequate understanding of HCDs in Radiology (81% post vs. 45% pre). Most program directors (75%) found the curriculum easy to implement.

CONCLUSION

This pilot study demonstrated that the APDR Health Care Disparities curriculum increased trainee awareness of HCDs. The curriculum also provided a forum for important discussions about HCDs.

An Upstream Reparative Justice Framework for Improving Diversity in Radiology

Healthcare workforce diversity is vital in combating health disparities. Despite much recent attention to downstream strategies to improve diversity in radiology, such as increased recruitment efforts and holistic application review, workforce diversity has not tangibly improved in recent decades. Yet, little discussion has been devoted to defining the obstacles which might delay, complicate, or altogether prevent persons from groups that have been traditionally marginalized and minoritized from a career in radiology. Refocusing attention to upstream barriers to medical education is vital to develop sustainable workforce diversity efforts in radiology. The purpose of this manuscript is to highlight the varied obstacles students and trainees from historically under-represented communities may face along the radiology career pathway and to provide concrete corollary programmatic solutions. Utilizing a reparative justice framework, which encourages race- and gender-conscious repair of historical injustices, and the socio-ecological model, which recognizes an individual's choices are informed by historical and ongoing systems of power, this manuscript advocates for tailored programs to improve justice, equity, diversity, and inclusion (JEDI) in radiology.

A Framework for Developing Health Equity Initiatives in Radiology

PURPOSE

In recent years, radiology departments have increasingly recognized the extent of health care disparities related to imaging and image-guided interventions. The goal of this article is to provide a framework for developing a health equity initiative in radiology and to articulate key defining factors.

METHODS

This article leverages the experience of three academic radiology departments and explores key principles that emerged when observing the experiences of these departments that have begun to engage in health equity-focused work.

RESULTS

A four-component framework is described for a health equity initiative in radiology consisting of (1) environmental scan and blueprint, (2) design and implementation, (3) initiative evaluation, and (4) community engagement. Key facilitators include a comprehensive environmental scan, early stakeholder engagement and consensus building, implementation science design thinking, and multitiered community engagement.

CONCLUSIONS

All radiology organizations should strive to develop, pilot, and evaluate novel initiatives that promote equitable access to high-quality imaging services. Establishing systems for high-quality data collection is critical to success. An implementation science approach provides a robust framework for developing and testing novel health equity initiatives in radiology. Community engagement is critical at all stages of the health equity initiative time line.

Barriers to Implementation of Breast Cancer Risk Assessment: The Health Care Team Perspective

PURPOSE

To assess health care professionals' perceptions of barriers to the utilization of breast cancer risk assessment tools in the public health setting through a series of one-on-one interviews with health care team members.

METHODS

We conducted a cross-sectional qualitative study consisting of one-on-one semistructured telephone interviews with health care team members in the public health setting in the state of Tennessee between May 2020 and October 2020. An iterative inductive-deductive approach was used for qualitative analysis of interview data, resulting in the development of a conceptual framework to depict influences of provider behavior in the utilization of breast cancer risk assessment.

RESULTS

A total of 24 interviews were completed, and a framework of influences of provider behavior in the utilization of breast cancer risk assessment was developed. Participants identified barriers to the utilization of breast cancer risk assessment (knowledge and understanding of risk assessment tools, workflow challenges, and availability of personnel); patient-level barriers as perceived by health care team members (psychological, economic, educational, and environmental); and strategies to increase the utilization of breast cancer risk assessment at the provider level (leadership buy-in, training, supportive policies, and incentives) and patient level (improved communication and better understanding of patients' perceived cancer risk and severity of cancer).

CONCLUSIONS

Understanding barriers to implementation of breast cancer risk assessment and strategies to overcome these barriers as perceived by health care team members offers an opportunity to improve implementation of risk assessment and to identify a racially, geographically, and socioeconomically diverse population of young women at high risk for breast cancer.

Black Women's Perspectives on Breast Cancer Risk Assessment

PURPOSE

The aim of this study was to gather the perspectives of Black women on breast cancer risk assessment through a series of one-on-one interviews.

METHODS

The authors conducted a cross-sectional qualitative study consisting of one-on-one semistructured telephone interviews with Black women in Tennessee between September 2020 and November 2020. Guided by the Health Belief Model, qualitative analysis of interview data was performed in an iterative inductive and deductive approach and resulted in the development of a conceptual framework to depict influences on a woman's decision to engage with breast cancer risk assessment.

RESULTS

A total of 37 interviews were completed, and a framework of influences on a woman's decision to engage in breast cancer risk assessment was developed. Study participants identified several emerging themes regarding women's perspectives on breast cancer risk assessment and potential influences on women's decisions to engage with risk assessment. Much of women's decision context was based on risk appraisal (perceived severity of cancer and susceptibility of cancer), emotions (fear and trust), and perceived risks and benefits of having risk assessment. The decision was further influenced by modifiers such as communication, the risk assessment protocol, access to health care, knowledge, and health status. Perceived challenges to follow-up if identified as high risk also influenced women's decisions to pursue risk assessment.

CONCLUSIONS

Black women in this study identified several barriers to engagement with breast cancer risk assessment. Efforts to overcome these barriers and increase the use of breast cancer risk assessment can potentially serve as a catalyst to address existing breast cancer disparities. Continued work is needed to develop patient-centric strategies to overcome identified barriers.

Using the Framework for Reporting Adaptations and Modifications-Expanded (FRAME) to study adaptations in lung cancer screening delivery in the Veterans Health Administration: a cohort study

BACKGROUND

Lung cancer screening is a complex clinical process that includes identification of eligible individuals, shared decision-making, tobacco cessation, and management of screening results. Adaptations to the delivery process for lung cancer screening in situ are understudied and underreported, with the potential loss of important considerations for improved implementation. The Framework for Reporting Adaptations and Modifications-Expanded (FRAME) allows for a systematic enumeration of adaptations to implementation of evidence-based practices. We applied FRAME to study adaptations in lung cancer screening delivery processes implemented by lung cancer screening programs in a Veterans Health Administration (VHA) Enterprise-Wide Initiative.

METHODS

We prospectively conducted semi-structured interviews at baseline and 1-year intervals with lung cancer screening program navigators at 10 Veterans Affairs Medical Centers (VAMCs) between 2019 and 2021. Using this data, we developed baseline (1st) process maps for each program. In subsequent years (year 1 and year 2), each program navigator reviewed the process maps. Adaptations in screening processes were identified, documented, and mapped to FRAME categories.

RESULTS

We conducted a total of 16 interviews across 10 VHA lung cancer screening programs (n=6 in year 1, n=10 in year 2) to collect adaptations. In year 1 (2020), six programs were operational and eligible. Of these, three reported adaptations to their screening process that were planned or in response to COVID-19. In year 2 (2021), all 10 programs were operational and eligible. Programs reported 14 adaptations in year 2. These adaptations were planned and unplanned and often triggered by increased workload; 57% of year 2 adaptations were related to the identification and eligibility of Veterans and 43% were related to follow-up with Veterans for screening results. Throughout the 2 years, adaptations related to data management and patient tracking occurred in 60% of programs to improve the data collection and tracking of Veterans in the screening process.

CONCLUSIONS

Using FRAME, we found that adaptations occurred primarily in the areas of patient identification and communication of results due to increased workload. These findings highlight navigator time and resource considerations for sustainability and scalability of existing and future lung cancer screening programs as well as potential areas for future intervention.

Gender Disparity in Surgical Device Patents: A 5-year Trend From Canada and the United States

INTRODUCTION

Despite an increasing number of women pursuing careers in science, engineering, and medicine, gender disparities in patents persist. This study sought to analyze trends in inventor's gender for surgical device patents filed and granted in Canada and the United States from 2015 to 2019.

METHODS

This study analyzed patents filed and granted by the Canadian Intellectual Property Office (CIPO) in the category of "Diagnosis; Surgery; Identification" and the United States Patent and Trademark Office (USPTO) in the category of "Surgery" from 2015 to 2019. The gender of the patent applicants was determined using a gender algorithm that predicts gender based on first names. Gender matches with names having a probability of less than 95% were excluded.

RESULTS

We identified 14,312 inventors on patents filed and 12,737 inventors on patents granted by the CIPO for "Diagnosis; Surgery; Identification". In the USPTO category of "Surgery," we identified 75,890 inventors on patents filed and 44,842 inventors on patents granted. Female inventors accounted for 7%-10% of inventors from 2015 to 2019 for both patents filed and granted. The proportion of female inventors on patents granted was significantly lower than for patents filed for four of the 5 y analyzed for both the USPTO and CIPO.

CONCLUSIONS

Female representation in surgical device patenting has stagnated, between 7 and 10%, from 2015 to 2019 in Canada and the United States. This underrepresentation of female inventors in surgical device patenting represents sizable gender disparity.

Using the Framework for Reporting Adaptations and Modifications-Expanded (FRAME) to study lung cancer screening adaptations in the Veterans Health Administration

Background: Lung cancer screening includes identification of eligible individuals, shared decision-making inclusive of tobacco cessation, and management of screening results. Adaptations to the implemented processes for lung cancer screening in situ are understudied and underreported, with potential loss of important considerations for improved implementation. The Framework for Reporting Adaptations and Modifications-Expanded (FRAME) allows for systematic enumeration of adaptations to implementations of evidence-based practices. We used FRAME to study adaptations in lung cancer screening processes that were implemented as part of a Veterans Health Administration (VHA) Enterprise-Wide Initiative. Methods: We conducted semi-structured interviews at baseline and 1-year intervals with lung cancer screening program navigators at 10 Veterans Affairs Medical Centers (VAMC) between 2019-2021. Using this data, we developed baseline (1st) process maps for each program. In subsequent years (year 1 and year 2), each program navigator reviewed the process maps. Adaptations in screening processes were identified, recorded and mapped to FRAME categories. Results: A total of 14 program navigators across 10 VHA lung cancer screening programs participated in 20 interviews. In year 1 (2019-2020), seven programs were operational and of these, three reported adaptations to their screening process that were either planned and in response to COVID-19. In year 2 (2020-2021), all 10 programs were operational. Programs reported 14 adaptations in year 2. These adaptations were both planned and unplanned and often triggered by increased workload; 57% of year 2 adaptations were related to identification and eligibility of Veterans and 43% were related to follow-up with Veterans for screening results. Throughout the 2 years, adaptations related to data management and patient tracking occurred in 6 of 10 programs to improve the data collection and tracking of Veterans in the screening process. Conclusions: Using FRAME, we found that adaptations occurred throughout the lung cancer screening process but primarily in the areas of patient identification and communication of results. These findings highlight considerations for lung cancer screening implementation and potential areas for future intervention.

Strategies to Improve Racial and Ethnic Diversity in Breast Imaging Training and Beyond

Diversity and inclusion in breast imaging can improve creativity and innovation, enrich the workplace environment, and enhance culturally appropriate care for an increasingly diverse patient population. Current estimates predict the racial and ethnic demographics of the United States population will change markedly by the year 2060, with increases in representation of the Black demographic projected to comprise 15% of the population (currently 13.3%) and the Hispanic/Latinx demographic projected to comprise 27.5% of the population (currently 17.8%). However, matriculation rates for those who are underrepresented in medicine (URM), defined as "racial and ethnic populations that are underrepresented in the medical profession relative to their numbers in the general population," have remained largely stagnant. Black students comprise only 7.1% of medical student matriculants, and Hispanic/Latinx students comprise only 6.2% of medical school matriculants compared to the general population. The matriculation rate of URM students into diagnostic radiology is even lower, with Black trainees comprising 3.1% of radiology residents and Hispanic/Latinx trainees comprising 4.8% of radiology residents. This lack of URM radiology resident representation leads to a lack of URM potential applicants to breast imaging fellowships due to the pipeline effect. Strategies to improve diversity and inclusion in breast imaging include recruiting a diverse breast imaging workforce, establishing robust mentorship and sponsorship programs, fostering an inclusive training and workplace environment, and retaining and promoting a diverse workforce.

An overview of genetic services delivery for hereditary breast cancer

Breast cancer is the most common cancer diagnosed in women worldwide, with approximately 5-10% of cases attributed to high penetrance hereditary breast cancer (HBC) genes. The tremendous advances in precision oncology have broadened indications for germline genetic testing to guide both systemic and surgical treatment, with increasing demand for cancer genetic services. The HBC continuum of care includes (1) identification, access, and uptake of genetic counseling and testing; (2) the delivery of genetic counseling and testing services; and (3) initiation of guideline-adherent follow-up care and family communication of results. Challenges to delivering care on the HBC care continuum include factors such as access to services, cost, discrimination and bias, and lack of education and awareness, which can be mitigated through implementing a multi-level approach. This includes strategies such as increasing awareness and utilization of genetic counseling and testing, developing new methods to meet the growing demand for genetic services, and improving the uptake of follow-up care by increasing patient and provider awareness of the management recommendations.

Health Care Disparities in Radiology-A Review of the Current Literature

INTRODUCTION

Health care disparities exist in all medical specialties, including radiology. Raising awareness of established health care disparities is a critical component of radiology's efforts to mitigate disparities. Our primary objective is to perform a comprehensive review of the last 10 years of literature pertaining to disparities in radiology care. Our secondary objective is to raise awareness of disparities in radiology.

METHODS

We reviewed English-language medicine and health services literature from the past 10 years (2010-2020) for research that described disparities in any aspect of radiologic imaging using radiology search terms and key words for disparities in OVID. Relevant studies were identified with adherence to the guidelines set forth by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement.

RESULTS

The search yielded a total 1,890 articles. We reviewed the citations and abstracts with the initial search yielding 1,890 articles (without duplicates). Of these, 1,776 were excluded based on the criteria set forth in the methods. The remaining unique 114 articles were included for qualitative synthesis.

DISCUSSION

We hope this article increases awareness and inspires action to address disparities and encourages research that further investigates previously identified disparities and explores not-yet-identified disparities.

Association of Rurality With Annual Repeat Lung Cancer Screening in the Veterans Health Administration

PURPOSE

Lung cancer causes the largest number of cancer-related deaths in the United States. Lung cancer incidence rates, mortality rates, and rates of advanced stage disease are higher among those who live in rural areas. Known disparities in lung cancer outcomes between rural and nonrural populations may be in part because of barriers faced by rural populations. The authors tested the hypothesis that among Veterans who receive initial lung cancer screening, rural Veterans would be less likely to complete annual repeat screening than nonrural Veterans.

METHODS

A retrospective cohort study was conducted of 10 Veterans Affairs medical centers from 2015 to 2019. Rural and nonrural Veterans undergoing lung cancer screening were identified. Rural status was defined using the rural-urban commuting area codes. The primary outcome was annual repeat lung cancer screening in the 9- to 15-month window (primary analysis) and 31-day to 18-month window (sensitivity analysis) after the first documented lung cancer screening. To examine rurality as a predictor of annual repeat lung cancer screening, multivariable logistic regression models were used.

RESULTS

In the final analytic sample of 11,402 Veterans, annual repeat lung cancer screening occurred in 27.7% of rural Veterans (641 of 2,316) and 31.8% of nonrural Veterans (2,891 of 9,086) (adjusted odds ratio: 0.86; 95% confidence interval: 0.73-1.03). Similar results were seen in the sensitivity analysis, with 41.6% of rural Veterans (963 of 2,316) versus 45.2% of nonrural Veterans (4,110 of 9,086) (adjusted odds ratio: 0.88; 95% confidence interval: 0.73-1.04) having annual repeat screening in the expanded 31-day to 18-month window.

CONCLUSIONS

Among a national cohort of Veterans, rural residence was associated with numerically lower odds of annual repeat lung cancer screening than nonrural residence. Continued, intentional outreach efforts to increase annual repeat lung cancer screening among rural Veterans may offer an opportunity to decrease deaths from lung cancer.

Image-guided Localization Techniques for Nonpalpable Breast Lesions: An Opportunity for Multidisciplinary Patient-centered Care

Selection of a localization method for nonpalpable breast lesions offers an opportunity for institutions to seek multidisciplinary input to promote value-based, patient-centered care. The diverse range of nonpalpable breast and axillary pathologies identified through increased utilization of screening mammography often necessitates image-guided preoperative localization for accurate lesion identification and excision. Preoperative localization techniques for breast and axillary lesions have evolved to include both wire and nonwire methods, the latter of which include radioactive seeds, radar reflectors, magnetic seeds, and radiofrequency identification tag localizers. There are no statistically significant differences in surgical outcomes when comparing wire and nonwire localization devices. Factors to consider during selection and adoption of image-guided localization systems include physician preference and ease of use, workflow efficiency, and patient satisfaction.

Historically Black Schools of Medicine Radiology Residency Programs: Contributions and Lessons Learned

INTRODUCTION

Black radiologists remain significantly underrepresented in the radiology workforce, despite a 1973 plea by Black radiologists of the National Medical Association to increase training programs for minority radiologists.

OBJECTIVE

The authors provide a qualitative narrative that highlights the radiology residency programs of three historically Black schools of medicine (HBSOM) in the U.S., their contributions, and lessons learned from their closure.

METHODS

Data from public repositories, interviews, and conversations were conflated to chronicle significant events and establish a timeline during these residency programs' existence.

RESULTS

Radiology residencies at Howard University School of Medicine (1945), Meharry Medical College (1949), and Charles R. Drew University of Medicine and Science (1972) were established to train Black doctors to treat communities of color. These programs provided care to underserved and under-resourced areas of the country, where inequitable health care fueled a legacy of poor health outcomes. These radiology residency programs collapsed under the weight of suboptimal funding, strapped capital budgets, attrition of faculty, a declining hospital patient census, and failure to maintain other residency specialty programs.` CONCLUSION: Understanding the history and impact of these programs, and of their closure, can be leveraged to develop strategies to increase the representation of racial and ethnic minorities in radiology. Possible reinstatement, with appropriate allocation of resources and creation of intentional policies to ensure sustained success, merits further investigation and may be a pathway to achieve optimal representation.

A lactation credit model to support breastfeeding in radiology: The new gold standard to support "liquid gold"

Breastfeeding has medical and economic benefits and providing an environment supportive of breastfeeding should be a priority in radiology to promote diversity, equity and inclusion. Most breastfeeding radiologists do not meet their breastfeeding goals and inadequate time for pumping is the most commonly cited barrier. The UCSF lactation credit model sets the standard for breastfeeding support in medicine by providing protected time without productivity penalties and it should be adapted and implemented across radiology practices to more fully support breastfeeding radiologists and radiation oncologists.

Representation of Women in Diagnostic Radiology Residency Programs: Does National Institutes of Health Program Ranking Matter?

PURPOSE

Women are consistently underrepresented in the radiology workforce. The authors examined recent trends in the gender distribution of residents entering diagnostic radiology residency programs.

METHODS

A retrospective review was performed of residents entering US diagnostic radiology residency programs for graduate medical education years 2009 to 2018. Demographic and program data were obtained from the Association of American Medical Colleges GME Track Resident Survey. National Institutes of Health (NIH) ranking was determined according to the Academy for Radiology & Biomedical Imaging Research. Descriptive statistical analyses were performed to evaluate the gender distribution of residents according to residency program ranking.

RESULTS

The final analytic sample included 11,788 residents who entered diagnostic radiology residency programs during the study period, of whom 3,245 (27.5%) were women and 8,543 (72.5%) were men. A higher percentage of female residents entered programs ranked in NIH rank group 1st to 20th (351 of 1,185 [29.6%]) than entered programs that were ranked lower than 20th or were unranked (1,540 of 5,819 [26.5%]; P = .026).

CONCLUSIONS

The present findings confirm repeated reports that women are underrepresented in radiology. The results indicate a need for further study on why a greater proportion of female residents are entering programs with higher NIH rankings. Better understanding of factors and interventions that led to this rise in the percentage of women in higher ranked programs provides an opportunity to expand gender diversity across the field of radiology.

Organizational Readiness for Lung Cancer Screening: A Cross-Sectional Evaluation at a Veterans Affairs Medical Center

OBJECTIVES

Lung cancer has the highest cancer-related mortality in the United States and among Veterans. Screening of high-risk individuals with low-dose CT (LDCT) can improve survival through detection of early-stage lung cancer. Organizational factors that aid or impede implementation of this evidence-based practice in diverse populations are not well described. We evaluated organizational readiness for change and change valence (belief that change is beneficial and valuable) for implementation of LDCT screening.

METHODS

We performed a cross-sectional survey of providers, staff, and administrators in radiology and primary care at a single Veterans Affairs Medical Center. Survey measures included Shea's validated Organizational Readiness for Implementing Change (ORIC) scale and Shea's 10 items to assess change valence. ORIC and change valence were scored on a scale from 1 to 7 (higher scores representing higher readiness for change or valence). Multivariable linear regressions were conducted to determine predictors of ORIC and change valence.

RESULTS

Of 523 employees contacted, 282 completed survey items (53.9% overall response rate). Higher ORIC scores were associated with radiology versus primary care (mean 5.48, SD 1.42 versus 5.07, SD 1.22, β = 0.37, P = .039). Self-identified leaders in lung cancer screening had both higher ORIC (5.56, SD 1.39 versus 5.11, SD 1.26, β = 0.43, P = .050) and change valence scores (5.89, SD 1.21 versus 5.36, SD 1.19, β = 0.51, P = .012).

DISCUSSION

Radiology health professionals have higher levels of readiness for change for implementation of LDCT screening than those in primary care. Understanding health professionals' behavioral determinants for change can inform future lung cancer screening implementation strategies.

Protocol to evaluate an enterprise-wide initiative to increase access to lung cancer screening in the Veterans Health Administration

INTRODUCTION

The Veterans Affairs Partnership to increase Access to Lung Screening (VA-PALS) is an enterprise-wide initiative to implement lung cancer screening programs at VA medical centers (VAMCs). VA-PALS will be using implementation strategies that include program navigators to coordinate screening activities, trainings for navigators and radiologists, an open-source software management system, tools to standardize low-dose computed tomography image quality, and access to a support network. VAMCs can utilize strategies according to their local needs. In this protocol, we describe the planned program evaluation for the initial 10 VAMCs participating in VA-PALS.

MATERIALS AND METHODS

The implementation of programs will be evaluated using the Consolidated Framework for Implementation Research to ensure broad contextual guidance. Program evaluation measures have been developed using the Reach, Effectiveness, Adoption, Implementation and Maintenance framework. Adaptations of screening processes will be assessed using the Framework for Reporting Adaptations and Modifications to Evidence Based Interventions. Measures collected will reflect the inner settings, estimate and describe the population reached, adoption by providers, implementation of the programs, report clinical outcomes and maintenance of programs. Analyses will include descriptive statistics and regression to evaluate predictors and assess implementation over time.

DISCUSSION

This theory-based protocol will evaluate the implementation of lung cancer screening programs across the Veterans Health Administration using scientific frameworks. The findings will inform plans to expand the VA-PALS initiative beyond the original sites and can guide implementation of lung cancer screening programs more broadly.

Educational Strategies to Achieve Equitable Breast Imaging Care

As the population of the United States becomes increasingly diverse, radiologists must learn to both understand and mitigate the impact of health disparities. Significant health disparities persist in radiologic care, including breast imaging. Racial and ethnic minorities, women from lower socioeconomic status, those living in rural areas, and the uninsured bear a disproportionate burden of breast cancer morbidity and mortality. Currently, there is no centralized radiology curriculum focusing on breast health disparities available to residents, breast imaging fellows, or practicing breast radiologists. While patient-, provider-, and system-level initiatives are necessary to overcome disparities, our purpose is to describe educational strategies targeted to breast imaging radiologists at all levels to provide equitable care to a diverse population. These strategies may include, but are not limited to, diversifying the breast imaging workforce, understanding the needs of a diverse population, cultural sensitivity and bias training, and fostering awareness of the existing issues in screening mammography access, follow-up imaging, and clinical care.

Abstract PS7-34: The association of race and socioeconomic status with overall survival in women with breast cancer in the southern community cohort study

Background:Breast cancer outcomes in minority and low socioeconomic status populations are not clearly defined due to underrepresentation of these underserved populations in breast cancer clinical trials and population-based studies. The Southern Community Cohort Study (SCCS), a prospective cohort of underserved, predominantly Black participants, provides a unique opportunity to evaluate disparities in breast cancer outcomes. We sought to examine the association between race and socioeconomic status (SES) and overall survival (OS) in women with localized breast cancer in the SCCS.

Methods:The SCCS enrolled approximately 86,000 participants aged 40-79 from 12 Southeastern states between 2002-2009, 86% of whom were enrolled at Community Health Centers. This analysis includes women diagnosed with incident localized breast cancer (stage I-III) identified through annual cohort linkage with 12 state cancer registries through December 20, 2017. Demographic data including participant age, self-reported history of diagnosed diabetes, body mass index (BMI), race, annual household income, and insurance coverage were obtained from baseline surveys. Tumor grade and stage were obtained from state cancer registries, and survival data were obtained from death registry records. Immunohistochemical (IHC) subtype was determined from tumor estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2) status obtained from cancer registry records and pathology reports. Survival time was defined as the number of months between initial breast cancer diagnosis and death from any cause. Descriptive analyses including mean (standard deviation) and number (%) were used to summarize clinical and sociodemographic characteristics by race. Multivariable Cox survival analysis was used to evaluate OS by race and annual household income, adjusting for age, insurance, stage, IHC subtype, diabetes, and BMI.

Results:Of the 1347 women diagnosed with incident breast cancer, 1016 had localized disease (stage I-III) and comprised our analytic sample. Compared to White women, Black women were more likely to have lower income, higher prevalence of triple negative breast cancer (TNBC), grade III tumors and stage III breast cancer (Table 1). After adjusting for clinical and sociodemographic factors, Black women had similar OS compared to White women (HR 0.67; 95% CI 0.42-1.07). However, after adjusting for race, women with a household income ≥ $25,000 had an improved OS compared to those with annual household income &lt; $25,000 (HR 0.53; 95% CI 0.30-0.93).

Conclusion: In a low-income, medically underserved population, Black women with localized breast cancer had similar OS compared to White women. However, socioeconomic disparities were observed, with worse OS for women with low annual household income. Future studies focused on minority, underserved groups are imperative to better understand the non-biological and biological factors contributing to disparities in survival among women with breast cancer.

Abstract PD11-05: Diabetes decreases overall survival in women with breast cancer in the southern community cohort study

Background:Factors contributing to breast cancer survival disparities in underrepresented racial and ethnic groups and low-income populations are poorly understood as few clinical trials and population based studies have included these underserved populations. The Southern Community Cohort Study (SCCS), a prospective cohort of underserved, low-income adults with high representation of Black participants, provides a unique opportunity to evaluate such disparities in cancer outcomes. A previous study utilizing SCCS data found no evidence of increased breast cancer risk among women with diabetes in this population. The purpose of this study was to evaluate the association of diabetes with overall survival in women with breast cancer in the SCCS.

Methods:The SCCS enrolled approximately 86,000 participants aged 40-79 from 12 southeastern states between 2002-2009, 86% of whom were enrolled at Community Health Centers. This analysis includes women diagnosed with incident localized breast cancers identified through annual cohort linkage with 12 state cancer registries. Demographic data including participant age at breast cancer diagnosis, self-reported history of diabetes (patient answered yes to “has a doctor ever told you that you have diabetes”), body mass index (BMI), race, household income, and insurance coverage were obtained from baseline surveys, cancer type and stage data from state cancer registries, and survival data from death registries. Survival time was defined as the number of months between initial breast cancer diagnosis and death from any cause. Descriptive characteristics including mean (standard deviation) or number (%) were used to summarize demographics. We used Pearson Chi-squared analysis to examine the association between diabetes and overall survival. Multivariable Cox proportional hazards regression was used to evaluate overall survival and diabetes, adjusting for covariates including age (continuous), race, BMI (categorical by WHO classifications), household income (binary – annual income &lt;$25,000, annual income &gt;=$25,000), insurance coverage, cancer subtype, and cancer stage).

Results:We identified a total of 1,347 women diagnosed with breast cancer. Of these, 1,016 were diagnosed with localized disease (stage 1-3) and comprised our analytic sample. Difference in denominators reflects missing data. The women were predominantly Black (667/1,016, 65.6%), low income (719/1,016 annual income less than $25,000, 70.8%), and insured (Private insurance 220/763, 28.8%; Medicare 331/763, 43.4%; Medicaid 178/763, 23.3%). Average age at diagnosis was 60.7 years (SD 9.1, IQR 41-88). Approximately one quarter of the patients (258/994, 26.0%) self-reported diabetes and 59.6% (605/1,016) were obese (BMI &gt;=30). The breast cancer immunohistochemistry subtypes in this cohort of women included HR+HER2- (392/564, 69.5%), HR+,HER2+ (55/564, 9.8%), HR-,HER2+ (31/564, 5.5%), and HR-HER2- (86/564, 15.3%). Women with diabetes had lower overall survival (174/258, 67.4%) than women without diabetes (587/746, 79.8%) (p&lt;0.0001). In the adjusted multivariate Cox regression model, diabetes significantly decreased overall survival in women with breast cancer, hazard ratio 1.87, 95% Confidence Interval [CI] = 1.12-3.09.

Conclusion:

In a low-income, predominantly Black population with incident localized breast cancer, decreased overall survival was observed among women diabetes compared to those without diabetes. Future studies should explore additional biological, societal, and socio-economic factors affecting survival among women with breast cancer in medically underserved minority populations.

Evidence-based smoking cessation treatment: a comparison by healthcare system

BACKGROUND

A systems-level approach to smoking cessation treatment may optimize healthcare provider adherence to guidelines. Institutions such as the Veterans Health Administration (VHA) are unique in their systematic approach, but comparisons of provider behavior in different healthcare systems are limited.

METHODS

We surveyed general medicine providers and specialists in a large academic health center (AHC) and its affiliated VHA in the Mid-South in 2017 to determine the cross-sectional association of healthcare system in which the provider practiced (exposure: AHC versus VHA) with self-reported provision of evidence-based smoking cessation treatment (delivery of counseling plus smoking cessation medication or referral) at least once in the past 12 months (composite outcome). Multivariable logistic regression with adjustment for specialty was performed in 2017-2019.

RESULTS

Of 625 healthcare providers surveyed, 407 (65%) responded, and 366 (59%) were analyzed. Most respondents practiced at the AHC (273[75%] vs VHA 93[25%]) and were general internists (215[59%]); pulmonologists (39[11%]); hematologists/oncologists (69[19%]); and gynecologists (43[12%]). Most respondents (328[90%]) reported the primary outcome. The adjusted odds of evidence-based smoking cessation treatment were higher among VHA vs. AHC healthcare providers (aOR = 4.3; 95% CI 1.3-14.4; p = .02). Health systems differed by provision of individual treatment components, including smoking cessation medication use (98% VHA vs. 90% AHC, p = 0.02) and referral to smoking cessation services (91% VHA vs. 65% AHC p = 0.001).

CONCLUSIONS

VHA healthcare providers were significantly more likely to provide evidence-based smoking cessation treatment compared to AHC healthcare providers. Healthcare systems' prioritization of and investment in smoking cessation treatment is critical to improving providers' adherence to guidelines.

The Status of Diversity in Canadian Radiology-Where We Stand and What Can We Do About It

Radiology has been identified as one of the medical specialties with the least gender, racial, and ethnic diversity. Despite the demonstrated benefits of gender and race diversity in medicine and industry, including innovation, empathy and improved patient outcomes, diversity in radiology in Canada is still lacking. In 2019, women represented around 63% of current medical graduates. However, within Canadian radiology practices, only 31.6% of radiologists are women. Women are also underrepresented in academic positions and the widening gender gap is present at higher academic ranks, indicating that women may not advance through academic hierarchies at the same pace as men. Although data on racial diversity in Canadian radiology practices is currently lacking, the representation of visible minorities in the general Canadian population is not reflected across Canadian radiology practices. Similarly, despite the Canadian Truth and Reconciliation Commission calling for action to increase the number of Indigenous healthcare workers, Indigenous people remain underrepresented in medicine and radiology. The importance of increasing diversity in radiology has gained recognition in recent years. Many solutions and strategies for national associations and radiology departments to improve diversity have been proposed. Leadership commitment is required to implement these programs to increase diversity in radiology in Canada with the ultimate goal of improving patient care. We review the current literature and available data on diversity within radiology in Canada, including the status of gender, race/ethnicity, and Indigenous people. We also present potential solutions to increase diversity.

Challenges faced by women in radiology during the pandemic - A summary of the AAWR Women's Caucus at the ACR 2020 annual meeting

The COVID-19 pandemic has dramatically altered the professional and personal lives of radiologists and radiation oncologists. This article summarizes the 2020 American Association for Women in Radiology (AAWR) Women's Caucus at the American College of Radiology (ACR) Annual Meeting. The caucus focused on the major challenges that women in radiology have faced during the pandemic.

Low Provider Knowledge Is Associated With Less Evidence-Based Lung Cancer Screening

BACKGROUND

Despite widespread recommendation and supportive policies, screening with low-dose CT (LDCT) is incompletely implemented in the US healthcare system. Low provider knowledge of the lung cancer screening (LCS) guidelines represents a potential barrier to implementation. Therefore, we tested the hypothesis that low provider knowledge of guidelines is associated with less provider-reported screening with LDCT.

PATIENTS AND METHODS

A cross-sectional survey was performed in a large academic medical center and affiliated Veterans Health Administration in the Mid-South United States that comprises hospital and community-based practices. Participants included general medicine providers and specialists who treat patients aged >50 years. The primary exposure was LCS guideline knowledge (US Preventive Services Task Force/Centers for Medicare & Medicaid Services). High knowledge was defined as identifying 3 major screening eligibility criteria (55 years as initial age of screening eligibility, smoking status as current or former smoker, and smoking history of ≥30 pack-years), and low knowledge was defined as not identifying these 3 criteria. The primary outcome was self-reported LDCT order/referral within the past year, and the secondary outcome was screening chest radiograph. Multivariable logistic regression evaluated the adjusted odds ratio (aOR) of screening by knowledge.

RESULTS

Of 625 providers recruited, 407 (65%) responded, and 378 (60.5%) were analyzed. Overall, 233 providers (62%) demonstrated low LCS knowledge, and 224 (59%) reported ordering/referring for LDCT. The aOR of ordering/referring LDCT was less among providers with low knowledge (0.41; 95% CI, 0.24-0.71) than among those with high knowledge. More providers with low knowledge reported ordering screening chest radiographs (aOR, 2.7; 95% CI, 1.4-5.0) within the past year.

CONCLUSIONS

Referring provider knowledge of LCS guidelines is low and directly proportional to the ordering rate for LDCT in an at-risk US population. Strategies to advance evidence-based LCS should incorporate provider education and system-level interventions to address gaps in provider knowledge.
