Gender and racial disparities in the transplant surgery workforce

Utility and bias in psychosocial evaluations for transplant listing

PURPOSE OF REVIEW

Disparities in access to transplantation are persistent and pervasive among minoritized populations, and remain incompletely explained by socioeconomic status, insurance, geography, or medical factors. Although much attention has been paid to factors contributing to disparities in organ allocation, fewer studies have focused on barriers to the transplant waitlist. Given increasing calls for equity in organ transplantation, we examine the role of nonmedical factors used in transplant listing decisions, including psychosocial factors like social support, motivation, and knowledge in improving utility in transplant listing decisions, as well as their potential for reinforcing bias.

RECENT FINDINGS

Minoritized groups are more likely to be declined from transplant listing owing to psychosocial criteria. Lack of consistent definitions, screening tools with differential subgroup validity, and insufficient evidence-base contribute to concerns about reliance on psychosocial factors in transplant listing decisions.

SUMMARY

Improving consistency and evidence-based approaches in patient evaluation and listing decisions will require greater efforts to identify which psychosocial risk factors are predictive of posttransplant outcomes. Social needs screening presents a strengths-based framework for incorporating psychosocial factors in transplant listing decisions.

Is Recognition in Transplant Surgery Equitable? A Two-decade Analysis of Transplant Award Recipients

INTRODUCTION

Awards from medical societies aim to recognize contributions and support academic growth. However, women and individuals from marginalized backgrounds are often underrepresented. This analysis examined the demographics of award recipients and award committee members from the American Society of Transplant Surgeons and American Society of Transplantation over 2 decades.

MATERIALS AND METHODS

Six American Society of Transplant Surgeons (ASTS) awards from 1995 to 2023 and 15 The American Society of Transplantation (AST) awards from 2000 to 2023 were assessed. Publicly available databases provided demographic data for recipients and committee members, categorized by race/ethnicity (non-Hispanic White, Black, Asian, and Hispanic) and sex (male and female). Recipients' highest degrees attained, professions, and institution affiliations were also gathered. The NIH's Research Portfolio Online Reporting Tool was used to examine the amount of NIH funding allocated to the recipients' affiliated institutions.

RESULTS

76.8% of recipients were non-Hispanic White, 14.4% Asian, 6.1% Hispanic, and 2.8% Black. The majority of awardees were surgeons at 37%, while 78% held MD credentials. The proportion of female award recipients was increased by 19% for AST and 33% for ASTS over the examined timeframe. No significant shifts were observed in the racial composition of award recipients for both AST and ASTS. More awards were given to individuals affiliated with institutions ranked in the top quartile for NIH funding for both AST and ASTS awards (P = 0.039; P = 0.018).

CONCLUSIONS

Among the two transplant surgery societies, recognition of female recipients has significantly increased. However, equitable recognition of individuals from underrepresented backgrounds remains insufficient. Further progress is needed to acknowledge the contributions of those from diverse backgrounds and professions.

Organizational change using a novel, structured plan for justice, equity, diversity, and inclusion (JEDI) in an academic surgical department

INTRODUCTION

Ethnic, gender-based, socioeconomic, and racial inequities persist in academic medical centers across the United States. Integration of principles of justice, equity, diversity, and inclusion (JEDI) with policies, procedures and organizational culture remains a challenge for many departments of Surgery.

METHODS

Starting in June of 2021, we implemented a structured justice, equity, diversity, and inclusion plan with the goal of enhancing organizational and cultural change within our department. We defined 3- to 5-year goals and tactics for meeting them, process and outcome measures, anticipated barriers, and strategies for navigating these barriers. We used metrics including an internal database and a faculty wellness survey. The plan was evaluated and validated by an external, independent committee appointed by the school of medicine, which provided a framework in addition to subsequent logistical and financial support.

RESULTS

A surgery vice chair for justice, equity, diversity, and inclusion and a justice, equity, diversity, and inclusion committee were established. We developed a mission statement, and formed 3 subcommittees focusing on Retention/Recruitment, Education, and Research. Key goals outlined in the plan included: formal restructuring of recruitment policies to include justice, equity, diversity, and inclusion language, integration of this language with university-wide policies and procedures, improvements to the family leave policy, increased recruitment and retention of surgical faculty from diverse backgrounds; and addition of evidence-based justice, equity, diversity, and inclusion instruction to conferences and education programs.

CONCLUSION

Development of a structured for justice, equity, diversity, and inclusion, supported by our academic governance, resulted in significant changes to policies and procedures both within and beyond our department of surgery. Formal internal and external outcome measures should be used and refined to objectively monitor goals and organizational change.

The status of diversity in the heart transplant workforce

Cardiac surgery and cardiology consistently have the lowest representation of women and racial minorities among all the specialties. The poor representation of minorities and women in cardiology and cardiac surgery is compounded by the fact that heart failure risk continues to rise in the United States (US) and disproportionately affects non-white patients. Inclusion in academia is imperative in diversifying the workforce and in turn, in improving the care we provide to all of our patients.

Rewriting the Future of Transplant and Vascular Surgery: Survey Suggests Vascular Surgery Workforce Available to Increase Retention and Recruitment in Transplant

OBJECTIVES

The specialties of vascular surgery and transplant surgery have had difficulties in recruitment and retention of professionals.

MATERIALS AND METHODS

We e-mailed a 10-question survey to a distribution list compiled from peerreviewed vascular surgery journals and Professional online profiles associated with the vascular community. Respondents interested in transplant or in a kidney transplant-vascular curricula merger were labeled as "invested" in transplant. The characteristics of respondents invested in transplant versus respondents invested in vascular-only pathway (not invested) were compared with the Fisher exact test and multivariable logistic regression. We used STATA for analyses, with P ≤ .05 as an indication of significance.

RESULTS

Of 113 respondents, 56 (50%) reported a current interest in organ transplantation. Within the interested group, most (66%, 38/58) favored renal only training. The invested group (55% 62/113) had higher interest in fellowship than the group not invested (P = .002) and favored a shorter fellowship for kidneyonly and combined kidney-liver training (P = .001 and P = .04,respectively). An additional 21 were interested in transplant training integrated with residency but not a fellowship, totaling a cumulative 73% (83/113) with interestin transplanttraining. Respondents older than aged 50 years and attending vascular surgeons (0+5) had significantly decreased investment in transplant (P = .027 and P = .033), respectively.

CONCLUSIONS

A robust vascular surgery workforce with an interest in organ transplant training is potentially available. Surgeons trained in vascular transplant would require a vascular transplant pathway to be established, which could diversify skills and may increase diversity, equity, and inclusion.

The Impact of Race and Ethnicity in Microvascular Head and Neck Reconstruction Postoperative Outcomes: A Nationwide Data Analysis

BACKGROUND

Racial and ethnic disparities have been extensively reported across surgical specialties, highlighting existing healthcare inequities. Nevertheless, evidence is lacking regarding their influence on postoperative outcomes after head and neck reconstruction. This study aimed to evaluate the impact of race and ethnicity on postoperative complications in head and neck microvascular reconstruction.

METHODS

The ACS-NSQIP database was used to identify patients who underwent head and neck microvascular reconstruction between 2012 and 2022. Baseline characteristics were compared based on race (White, non-White) and ethnicity (Hispanic, non-Hispanic). Group differences were assessed using t tests and Fisher Exact tests. Multivariable logistic regression models were constructed to evaluate postoperative complications between the groups. A Cochran-Armitage test was conducted to evaluate the significance of trends over time.

RESULTS

A total of 11,373 patients met inclusion criteria. Among them, 9,082 participants reported race, and 9,428 reported ethnicity. Multivariable analysis demonstrated that Hispanic patients were more likely to experience 30-day readmission (OR 6.7; 95% CI, 1.17-38.4; P=0.032) and had an average total length of stay of 5.25 days longer (95% CI, 0.84-9.65; P=0.020) compared with non-Hispanic patients. Additional subgroup analyses revealed higher rates of all readmissions among non-White patients, particularly those indicated by malignancy (OR 1.23; 95% CI, 1.1-1.4; P=0.002). No significant differences were found in mortality, reoperation rates, and operative times between racial and ethnic groups.

CONCLUSIONS

The findings of this study suggest that ethnicity may be a significant risk factor for readmission in head and neck microvascular reconstruction. However, future studies are needed to further clarify the impact of race and ethnicity on longer postoperative outcomes, particularly in head and neck cancer minorities.

Clinical Research in Renal Transplantation: A Bibliometric Perspective on a Half-century of Innovation and Progress

BACKGROUND

Groundbreaking biomedical research has transformed renal transplantation (RT) into a widespread clinical procedure that represents the mainstay of treatment for end-stage kidney failure today. Here, we aimed to provide a comprehensive bibliometric perspective on the last half-century of innovation in clinical RT.

METHODS

The Web of Science Core Collection was used for a comprehensive screening yielding 123 303 research items during a 50-y period (January 1973-October 2022). The final data set of the 200 most-cited articles was selected on the basis of a citation-based strategy aiming to minimize bias.

RESULTS

Studies on clinical and immunological outcomes (n = 63 and 48), registry-based epi research (n = 38), and randomized controlled trials (n = 35) dominated the data set. Lead US authors have signed 110 of 200 articles. The overall level of evidence was high, with 84% of level1 and -2 reports. Highest numbers of these articles were published in New England Journal of Medicine , Transplantation , and American Journal of Transplantation. Increasing trend was observed in the number of female authors in the postmillennial era (26% versus 7%).

CONCLUSIONS

This study highlights important trends in RT research of the past half-century. This bibliometric perspective identifies the most intensively researched areas and shift of research interests over time; however, it also describes important imbalances in distribution of academic prolificacy based on topic, geographical aspects, and gender.

The Evolving Plastic Surgery Applicant: How Far Have We Come in 30 Years?

BACKGROUND

Plastic surgery training has undergone tremendous change and transitioned through many models over the years, including independent, combined, and integrated. This study evaluates how these changes and others have affected plastic surgery applicants' demographics and academic qualifications over the last 30 years.

METHODS

Data on applicant demographics and academic qualifications were extracted from multiple sources including the National Resident Matching Program, the American Association of Medical Colleges, and cross-sectional surveys of plastic surgery applicants for the years 1992, 2005, 2011, and 2022. Data were compared using pairwise χ2 goodness of fit tests.

RESULTS

The sex distribution of plastic surgery applicants changed significantly over the last 30 years: whereas men predominated in 1992 (86% male vs 14% female), by 2011, the distribution was nearly equal (54% male vs 46% female in both 2011 and 2022, P < 0.001).The racial makeup of applicants also changed over time (P < 0.05). White applicants decreased from 73% in 1992 to 55% in 2011, and 53% in 2022. While there was an increase in Asian (7% to > 17% to > 20%) and other (13% to > 14% to > 21%) applicants over time, whereas the proportion of Black applicants remained stagnant (5% to > 6% to > 8%).Applicants with prior general surgery experience declined precipitously over the years: 96% in 1992, 64% in 2005, 37% in 2011, and 26% in 2022 (P < 0.001). When compared with 1992, Alpha Omega Alpha status increased significantly in 2011 (36% vs 12%, P < 0.05) but did not change considerably in 2005 (22%) and 2022 (23%). Research experience increased dramatically over the years, with the proportion of applicants with at least one publication going from 43% in 1992, to 75% in 2005, to 89% in 2011, and to 99% in 2022 (P < 0.001). Applicant interest in academic plastic surgery did not change considerably over the years at roughly ranging from 30% to 50% of applicants (P = ns).

CONCLUSIONS

There has been a shift in the demographics and academic qualifications of plastic surgery applicants over the last 3 decades. Understanding this evolution is critical for reviewing and evaluating the makeup of our specialty, and enacting changes to increase representation where necessary.

Importance of Diversity, Equity, and Inclusion in the Hepatopancreatobiliary Workforce

Diversity is a catalyst for progress that prevents institutional stagnation and, by extension, averts descent to mediocrity. This review focuses on the available data concerning hepatopancreatobiliary (HPB) surgical workforce demographics and identifies evidence-based strategies that may enhance justice, equity, diversity, and inclusion for HPB surgeons and their patients. We report that the current United States HPB surgical workforce does not reflect the population it serves. We review data describing disparity-perpetuating hurdles confronting physicians from minority groups underrepresented in medicine at each stage of training. We further examine evidence showing widespread racial and socioeconomic disparities in HPB surgical care and review the effects of workforce diversity and physician-patient demographic concordance on healthcare outcomes. Evidence-based mitigators of structural racism and segregation are reviewed, including tailored interventions that can address social determinants of health toward the achievement of true excellence in HPB surgical care. Lastly, select evidence-based data driving surgical workforce solutions are reviewed, including intentional compensation plans, mentorship, and sponsorship.

Equity, Diversity and Inclusion (EDI) in Organ Transplantation: An ESOT Survey About EDI Within ESOT as an Organization and its Educational Activities, and Transplantation Research and Science

The European Society of Organ Transplantation (ESOT) strives to promote equity, diversity, and inclusion (EDI) across all its activities. We surveyed the transplant community's experiences and perspectives regarding EDI within ESOT as an organization and its educational activities, and research in general. A total of 299 respondents completed the questionnaire. About half agreed that ESOT's Executive Committee, Council, and Sections/Committees are diverse and inclusive (51%) and that ESOT promotes EDI in its live and digital educational activities (54%). Forty percent of respondents agreed that scientific and clinical trials in the field of transplantation are diverse and inclusive. Despite the wide distribution of the survey, most of the respondents self-identified as White and were either physician or surgeon. However, the results contribute a unique insight into the experiences and perspectives of the transplantation community regarding EDI. Whilst ESOT is committed to the principles of EDI, perceptions and the high number of proposals show the apparent need to prioritize efforts to embed EDI across ESOT and transplantation science. These data should constitute a starting point for change and provide guidance for future efforts to promote EDI within the transplantation community.

Bias in Surgical Residency Evaluations: A Scoping Review

OBJECTIVE

Given widespread disparities in the surgical workforce and the advent of competency-based training models that rely on objective evaluations of resident performance, this review aims to describe the landscape of bias in the evaluation methods of residents in surgical training programs in the United States.

DESIGN

A scoping review was conducted within PubMed, Embase, Web of Science, and ERIC in May 2022, without a date restriction. Studies were screened and reviewed in duplicate by 3 reviewers. Data were described descriptively.

SETTING/PARTICIPANTS

English-language studies conducted in the United States that assessed bias in the evaluation of surgical residents were included.

RESULTS

The search yielded 1641 studies, of which 53 met inclusion criteria. Of the included studies, 26 (49.1%) were retrospective cohort studies, 25 (47.2%) were cross-sectional studies, and 2 (3.8%) were prospective cohort studies. The majority included general surgery residents (n = 30, 56.6%) and nonstandardized examination modalities (n = 38, 71.7%), such as video-based skills evaluations (n = 5, 13.2%). The most common performance metric evaluated was operative skill (n = 22, 41.5%). Overall, the majority of studies demonstrated bias (n = 38, 73.6%) and most investigated gender bias (n = 46, 86.8%). Most studies reported disadvantages for female trainees regarding standardized examinations (80.0%), self-evaluations (73.7%), and program-level evaluations (71.4%). Four studies (7.6%) assessed racial bias, of which all reported disadvantages for trainees underrepresented in surgery.

CONCLUSIONS

Evaluation methods for surgery residents may be prone to bias, particularly with regard to female trainees. Research is warranted regarding other implicit and explicit biases, such as racial bias, as well as for nongeneral surgery subspecialties.

Incidence of attrition among early-career abdominal transplant surgeons

BACKGROUND

The prevalence of burnout and depression among abdominal transplant surgeons has been well described. However, the incidence of early-career transplant surgeons leaving the field is unknown. The objective of this study was to quantify the incidence of attrition among early-career abdominal transplant surgeons.

METHODS

A custom database from the Organ Procurement and Transplantation Network with encrypted surgeon-specific identifiers was queried for transplant surgeons who entered the field between 2008 and 2019. Surgeons who experienced attrition, defined as not completing a subsequent transplant after a minimum of 5, were identified. Surgeon-specific case volumes, case mix, and recipient outcomes were modeled to describe their association with attrition.

RESULTS

Between 2008 and 2018, 496 abdominal transplant surgeons entered the field and performed 76,465 transplant procedures. A total of 24.4% (n = 121) experienced attrition, with a median time to attrition of 2.75 years. Attrition surgeons completed fewer kidney (7 vs 21, P < .01), pancreas (0.52 vs 1.43, P < .01), and liver transplants (1 vs 4, P < .01) in their first year of practice. Attrition surgeons completed a smaller proportion of their transplant center's volume (9% vs 18%, P < .01) and were less likely to participate in pediatric transplants (26.5% vs 52.5%, P < .01) and living donor kidney transplants (64.5% vs 84.5%, P < .01). On multivariable analysis, performing fewer kidney (odds ratio: 0.98, 95% confidence interval: 0.98-0.99) and liver transplants (odds ratio: 0.98, 95% confidence interval: 0.97-0.98) by year 5 and completing a smaller proportion of their centers' volume (odds ratio: 0.96, 95% confidence interval: 0.94-0.98) were associated with attrition. Furthermore, attrition surgeons had worse allograft and patient survival for liver transplant recipients (both log-rank P < .01).

CONCLUSION

This investigation was the first to quantify the high incidence of attrition experienced by early-career abdominal transplant surgeons and its association with surgeon-specific case volumes, case mix, and worse recipient outcomes. These findings suggested the abdominal transplant workforce is struggling to retain their fellowship-trained surgeons.

An Interval Look at the Transplant Surgery Pipeline: Insights from General Surgery Residents' Operative Experience Using ACGME Operative Logs from 2000 to 2021

OBJECTIVE

Given the declining number of US graduates pursuing transplant surgery as well as regulatory changes regarding transplant rotations for surgical residents, this study examined the transplant surgery operative volume of residents over the past 20 years.

DESIGN

Retrospective analysis of the ACGME database of general surgery operative logs from academic year (AY) 1999-2000 to AY 2020-2021; data was categorized into time periods relative to regulatory changes: Period 1 (1999-2010) and Period 2 (2011-2021).

SETTING/PARTICIPANTS

All ACGME-accredited general surgery residency programs in the US.

FINDINGS

On average, the proportion of transplant cases to all total major cases was about 1% and did not change during the study period (p=0.61). Each graduating resident completed an average of 10.0 ± 11.0 cases during Period 1 and 10.8 ± 12.0 cases during Period 2, representing a statistically but unlikely clinically significant increase (p=0.008). Renal transplants comprised more than 50% of each resident's operative experience in transplant surgery. The proportion of resident involvement in all renal and liver transplantations nationally did not change during the study period, ranging from 34.5-42.9% for renal and 13.8-22.4% for liver.

CONCLUSIONS

Resident volume in transplant surgery has largely remained consistent over the past 20 years, suggesting that changes in operative volume are unlikely driving declining interest in transplant surgery fellowship among US trainees.

Impact of racial, ethnic and gender disparities in Cardiology

Literature shows evidence of racial and gender biases in many sub-specialties of medicine including cardiology. Racial, ethnic, and gender disparities exist along the path to cardiology residency, beginning as early as medical school admissions. Approximately 65.62% White, 4.71% Black, 18.06% Asian, and 8.86% Hispanic are cardiologists, while there are a total of 60.1% White, 12.2% Black, 5.6% Asian, and 18.5% Hispanic people in the US in 2019, showing evident underrepresentation. Gender disparities have an inevitable role in the lack of a diverse cardiovascular workforce. According to a recent study, only 13% of practicing cardiologists in the US are women, even though the female population in the US is 50.52% as compared to 49.48%- of men. These disparities led to underrepresented physicians earning less than their similarly qualified counterparts, decreased equity, increased workplace harassment, and also results in patients facing unconscious bias from their physicians leading to deteriorated clinical outcomes. Implications in the field of research include the underrepresentation of minorities and the female population despite the increased burden of cardiovascular disease they face. However, efforts are underway to eradicate the disparities that exist in cardiology. This paper aims to increase awareness regarding the issue and inform future policies with the goal of encouraging underrepresented communities to join the cardiology workforce.

A Conceptual Model for Sources of Differential Selection in Lung Transplant Allocation

Rationale: In the United States, donor lungs are allocated to transplant candidates on the basis of lung allocation scores (LAS). However, additional factors beyond the LAS can impact who is transplanted, including listing and donor-organ acceptance practices. These factors can result in differential selection, undermining the objectivity of lung allocation. Yet their impact on the lung transplant pathway has been underexplored. Objectives: We sought to systematically examine sources of differential selection in lung transplantation via qualitative methods. Methods: We conducted semistructured qualitative interviews with lung transplant surgeons and pulmonologists in the United States between June 2019 and June 2020 to understand clinician perspectives on differential selection in lung transplantation and the LAS. Results: A total of 51 respondents (30 surgeons and 21 pulmonologists) identified many sources of differential selection arising throughout the pathway from referral to transplantation. We synthesized these sources into a conceptual model with five themes: 1) transplant center's degree of risk tolerance and accountability; 2) successfulness and fairness of the LAS; 3) donor-organ availability and regional competition; 4) patient health versus program health; and 5) access to care versus responsible stewardship of organs. Conclusions: Our conceptual model demonstrates how differential selection can arise throughout lung transplantation and facilitates the further study of such selection. As new organ allocation models are developed, differential selection should be considered carefully to ensure that these models are more equitable.

The job market for HPB surgeons: leadership perspectives on surgeon skillsets, training pathways, and hiring

BACKGROUND

Three tracks prepare Hepato-Pancreato-Biliary (HPB) surgeons: HPB, surgical oncology, and transplant fellowships. This study explored how surgical leaders thought about HPB surgery and evaluated potential candidates for HPB positions.

METHODS

This descriptive qualitative study utilized interviews of healthcare leaders whose responsibilities included hiring HPB surgeons. We coded inductively then used thematic network analysis to organize the data. Individual codes formed basic themes, then larger secondary themes, then finally "primary" themes.

RESULTS

Primary themes were: (1) What defines an HPB surgical practice?, (2) How do they assess candidates for HPB positions?, and (3) How will HPB practices continue to evolve? Leaders assessed applicants' training, behaviors and cultural fit, technical excellence, and more. Personal recommendations and professional networks significantly influenced the hiring process. HPB surgery needs were growing due to population changes, treatments advances, and changing market conditions.

DISCUSSION

Surgical societies should focus on facilitating networking, promoting transparency, sharing quality data, providing evidence of technical skills and teamwork, mentorship, and providing guidance to general surgery residency program directors. There is great interest in unification and cooperation across the profession, protocol standardization enhancing quality, continued workforce diversification, and evaluation of the alignment between training and practice.

Four Decades of Clinical Liver Transplantation Research: Results of a Comprehensive Bibliometric Analysis

BACKGROUND

Nearly 40 y have passed since the 1983 National Institutes of Health Consensus-Development-Conference, which has turned liver transplantation (LT) from a clinical experiment into a routine therapeutic modality. Since' clinical LT has changed substantially. We aimed to comprehensively analyze the publication trends in the most-cited top-notch literature in LT science over a 4-decade period.

METHODS

A total of 106 523 items were identified between January 1981 and May 2021 from the Web of Science Core Collection. The top 100 articles published were selected using 2 distinct citation-based strategies to minimize bias. Various bibliometric tools were used for data synthesis and visualization.

RESULTS

The citation count for the final dataset of the top 100 articles ranged from 251 to 4721. Most articles were published by US authors (n = 61). The most prolific institution was the University of Pittsburgh (n = 15). The highest number of articles was published in Annals of Surgery, Hepatology, and Transplantation ; however, Hepatology publications resulted in the highest cumulative citation of 9668. Only 10% of the articles were classified as evidence level 1. Over 90% of first/last authors were male. Our data depict the evolution of research focus over 40 y. In part, a disproportional flow of citations was observed toward already well-cited articles. This might also project a slowed canonical progress, which was described in other fields of science.

CONCLUSIONS

This study highlights key trends based on a large dataset of the most-cited articles over a 4-decade period. The present analysis not only provides an important cross-sectional and forward-looking guidance to clinicians, funding bodies, and researchers but also draws attention to important socio-academic or demographic aspects in LT.

A review of racial, socioeconomic, and geographic disparities in pediatric liver transplantation

Equity is a core principle in both pediatrics and solid organ transplantation. Health inequities, specifically across race, socioeconomic position, or geography, reflect a moral failure. Ethical principles of prudential life span, maximin principle, and fair innings argue for allocation priority to children related to the number of life years gained, equal access to transplant, and equal opportunity for ideal posttransplant outcomes. Iterative policy changes have aimed to narrow these disparities to achieve pediatric transplant equity. These policy changes have focused on modifying pediatric priority for organ allocation to eliminate mortality on the pediatric transplant waiting list. Yet disparities remain in pediatric liver transplantation at all time points: from access to referral for transplantation, likelihood of living donor transplantation, use of exception narratives, waitlist mortality, and inequitable posttransplant outcomes. Black children are less likely to be petitioned for exception scores, have higher waitlist mortality, are less likely to be the recipient of a living donor transplant, and have worse posttransplant outcomes compared with White children. Children living in the most socioeconomically deprived neighborhoods have worse posttransplant outcomes. Children living farther from a transplant center have higher waitlist mortality. Herein we review the current knowledge of these racial and ethnic, socioeconomic, and geographic disparities for these children. To achieve equity, stakeholder engagement is required at all levels from providers and health delivery systems, learning networks, institutions, and society. Future initiatives must be swift, bold, and effective with the tripartite mission to inform policy changes, improve health care delivery, and optimize resource allocation to provide equitable transplant access, waitlist survival, and posttransplant outcomes for all children.

Editorial: Disparities in transplantation access and outcomes: mind the gap!

Organ transplantation still remains a problem of supply and demand and presents multiple ethical challenges to our society. Despite numerous targeted interventions and policy reforms, women, underrepresented minorities and patients with low socioeconomic status (SES) continue to have unequal access to transplant. The purpose of this special edition is to highlight disparities in access to transplantation and posttransplant outcomes. Acknowledging that these disparities exist is the first step toward interventions aimed at mitigating this long-standing inequity. This issue provides 10 articles that give the background and summarize relevant literature describing these disparities and identify potential areas of intervention. Most of the data relates to the United States but may reflect patterns encounter in most societies. Each manuscript was written by leaders of international teams in the field of patient advocacy, public health or outcome research in transplantation.
