Should Transplant Nephrology Pursue Recognition from the Accreditation Council for Graduate Medical Education (ACGME)?

Kidney transplant is not only the best treatment for patients with advanced kidney disease but it also reduces health care expenditure. The management of transplant patients is complex as they require special care by transplant nephrologists who have expertise in assessing transplant candidates, understand immunology and organ rejection, have familiarity with perioperative complications, and have the ability to manage the long-term effects of chronic immunosuppression. This skill set at the intersection of multiple disciplines necessitates additional training in Transplant Nephrology. Currently, there are more than 250,000 patients with a functioning kidney allograft and over 100,000 waitlisted patients awaiting kidney transplant, with a burgeoning number added to the kidney transplant wait list every year. In 2022, more than 40,000 patients were added to the kidney wait list and more than 25,000 received a kidney transplant. The Advancing American Kidney Health Initiative, passed in 2019, is aiming to double the number of kidney transplants by 2030 creating a need for additional transplant nephrologists to help care for them. Over the past decade, there has been a decline in the Nephrology-as well Transplant Nephrology-workforce due to a multitude of reasons. The American Society of Transplantation Kidney Pancreas Community of Practice created a workgroup to discuss the Transplant Nephrology workforce shortage. In this article, we discuss the scope of the problem and how the Accreditation Council for Graduate Medical Education recognition of Transplant Nephrology Fellowship could at least partly mitigate the Transplant Nephrology work force crisis.

Liver transplantation from a SARS-COV-2-positive donor: A road ahead or not.

The COVID-19 pandemic has had a remarkable impact on the field of liver transplantation. Increasing evidence demonstrates a minimal risk of transmission of SARS-CoV-2 from non-lung donors who test positive for SARS-CoV-2; however, the risks of donor-derived SARS-CoV-2 from liver donors are unknown. We present our experience with two cases in which a liver was transplanted successfully from a brain-dead donor with incidental SARS-CoV-2 infection. Both donors were asymptomatic SARS-CoV-2-positive with negative bronchoalveolar lavage polymerase chain reaction (BAL PCR) and mechanism of death unrelated to COVID-19. Both the recipients did well after transplant and went home with a well-functioning liver. One patient did get readmitted and was found to be SARS-CoV-2-positive; however, it was probably related to hospital exposure rather than donor-derived. SARS-CoV-2-positive donors in select cases may be used for organ donation and liver transplant is safe for recipients.

Coronavirus Disease-2019 and Implications on the Liver.

The coronavirus disease-2019 (COVID-19) pandemic has had a large impact on patients with chronic liver disease (CLD) and liver transplantation (LT) recipients. Patients with advanced CLD are at a significantly increased risk of poor outcomes in the setting of severe acute respiratory syndrome coronavirus 2 infection. The pandemic has also considerably altered the management and care that is provided to patients with CLD, pre-LT patients, and LT recipients. Vaccination against COVID-19 protects patients with CLD and LT recipients from adverse outcomes and is safe in these patients; however, vaccine efficacy may be reduced in LT recipients and other immunosuppressed patients.

Palliative care experience and perceived gaps in training among transplant hepatology fellows: A national survey.

Despite the likely benefits of palliative care (PC) for patients with cirrhosis, physician experiences and perspectives about best practices are variable. We aimed to assess PC experience and gaps in training among transplant hepatology fellows. We conducted a national survey of all transplant hepatology fellows enrolled in accredited fellowship programs during the 2020-2021 academic year. We assessed the frequency of PC provision and comfort with physical and psychological symptom management, psychosocial care, communication skills, advance care planning, and end-of-life care. A total of 45 of 56 (79%) of transplant hepatology fellows responded to the survey; 50% (n = 22) were female. Most trained at centers performing over 100 transplants per year (67%, n = 29) distributed evenly across geographic regions. Most fellows (69%, n = 31) had a PC or hospice care rotation during residency, and 42% (n = 19) of fellows received education in PC during transplant hepatology fellowship. Fellows reported feeling moderately to very comfortable with communication skills such as breaking bad news (93%, n = 41) and leading family meetings (75%, n = 33), but nearly one-third (30%, n = 13) reported feeling not very or not at all comfortable assessing and managing anxiety and depression (30%, n = 13) and spiritual distress (34%, n = 15). Nearly one-quarter (22%, n = 10) had never discussed or documented advance care plans during fellowship. Fellows wished to receive future instruction on the assessment and management of physical symptoms (68%, n = 30) and anxiety and depression (64%, n = 28). Conclusion: Our survey highlights gaps in PC experience and education during transplant hepatology fellowship, lack of comfort in managing psychological distress and advance care planning, and desire to improve skills, particularly in symptom management. Future studies should investigate how to enhance transplant hepatology competencies in these PC domains and whether this impacts clinical care, advance care planning, or patient experience.

Artificial intelligence to identify harmful alcohol use after early liver transplant for alcohol-associated hepatitis.

Early liver transplantation (LT) for alcohol-associated hepatitis (AH) is the fastest growing indication for LT, but prediction of harmful alcohol use post-LT remains limited. Among 10 ACCELERATE-AH centers, we examined psychosocial evaluations from consecutive LT recipients for AH from 2006 to 2017. A multidisciplinary panel used content analysis to develop a maximal list of psychosocial variables. We developed an artificial intelligence model to predict post-LT harmful alcohol use. The cohort included training (N = 91 among 8 centers) and external validation (N = 25 among 2 centers) sets, with median follow-up of 4.4 (IQR 3.0-6.0) years post-LT. In the training set, AUC was 0.930 (95%CI 0.862-0.998) with positive predictive value of 0.891 (95%CI 0.620-1.000), internally validated through fivefold cross-validation. In the external validation set, AUC was 0.692 (95%CI 0.666-0.718) with positive predictive value of 0.82 (95%CI 0.625-1.000). The model identified specific variables related to social support and substance use as highly important to predict post-LT harmful alcohol use. We retrospectively developed and validated a model that identified psychosocial profiles at LT predicting harmful alcohol use post-LT for AH. This preliminary model may inform selection and post-LT management for AH and warrants prospective evaluation in larger studies among all alcohol-associated liver disease being considered for early LT.

Patterns of Alcohol Use After Early Liver Transplantation for Alcoholic Hepatitis.

BACKGROUND & AIMS: Early liver transplantation (LT) for alcoholic hepatitis (AH) is lifesaving but concerns regarding return to harmful alcohol use remain. We sought to identify distinct patterns of alcohol use post-LT to inform pre-LT candidate selection and post-LT addiction care. METHODS: Detailed post-LT alcohol use data was gathered retrospectively from consecutive patients with severe AH at 11 ACCELERATE-AH sites from 2006-2018. Latent class analysis identified longitudinal patterns of alcohol use post-LT. Logistic and Cox regression evaluated associations between patterns of alcohol use with pre-LT variables and post-LT survival. A microsimulation model estimated the effect of selection criteria on overall outcomes. RESULTS: Of 153 LT recipients, 1-, 3-, and 5-year survival were 95%, 88% and 82%. Of 146 LT recipients surviving to home discharge, 4 distinct longitudinal patterns of post-LT alcohol use were identified: Pattern 1 [abstinent](n = 103; 71%), pattern 2 [late/non-heavy](n = 9; 6.2%), pattern 3 [early/non-heavy](n = 22; 15%), pattern 4 [early/heavy](n = 12; 8.2%). One-year survival was similar among the 4 patterns (100%), but patients with early post-LT alcohol use had lower 5-year survival (62% and 53%) compared to abstinent and late/non-heavy patterns (95% and 100%). Early alcohol use patterns were associated with younger age, multiple prior rehabilitation attempts, and overt encephalopathy. In simulation models, the pattern of post-LT alcohol use changed the average life-expectancy after early LT for AH. CONCLUSIONS: A significant majority of LT recipients for AH maintain longer-term abstinence, but there are distinct patterns of alcohol use associated with higher risk of 3- and 5-year mortality. Pre-LT characteristics are associated with post-LT alcohol use patterns and may inform candidate selection and post-LT addiction care.

Alcohol-Associated Liver Disease Before and After COVID-19-An Overview and Call for Ongoing Investigation.

The Coronavirus Disease 2019 (COVID-19) pandemic has exacted a heavy toll on patients with alcohol-associated liver disease (ALD) and alcohol use disorder (AUD). The collective burden of ALD and AUD was large and growing, even before the COVID-19 pandemic. There is accumulating evidence that this pandemic has had a large direct effect on these patients and is likely to produce indirect effects through delays in care, psychological strain, and increased alcohol use. Now a year into the pandemic, it is important that clinicians fully understand the effects of the COVID-19 pandemic on patients with ALD and AUD. To fill existing gaps in knowledge, the scientific community must set research priorities for patients with ALD regarding their risk of COVID-19, prevention/treatment of COVID-19, changes in alcohol use during the pandemic, best use of AUD treatments in the COVID-19 era, and downstream effects of this pandemic on ALD. Conclusion: The COVID-19 pandemic has already inflicted disproportionate harms on patients with ALD, and ongoing, focused research efforts will be critical to better understand the direct and collateral effects of this pandemic on ALD.

American Association for the Study of Liver Diseases Expert Panel Consensus Statement: Vaccines to Prevent Coronavirus Disease 2019 Infection in Patients With Liver Disease.

The aim of this document is to provide a concise scientific review of the currently available COVID-19 vaccines and those in development, including mRNA, adenoviral vectors, and recombinant protein approaches. The anticipated use of COVID-19 vaccines in patients with chronic liver disease (CLD) and liver transplant (LT) recipients is reviewed and practical guidance is provided for health care providers involved in the care of patients with liver disease and LT about vaccine prioritization and administration. The Pfizer and Moderna mRNA COVID-19 vaccines are associated with a 94%-95% vaccine efficacy compared to placebo against COVID-19. Local site reactions of pain and tenderness were reported in 70%-90% of clinical trial participants, and systemic reactions of fever and fatigue were reported in 40%-70% of participants, but these reactions were generally mild and self-limited and occurred more frequently in younger persons. Severe hypersensitivity reactions related to the mRNA COVID-19 vaccines are rare and more commonly observed in women and persons with a history of previous drug reactions for unclear reasons. Because patients with advanced liver disease and immunosuppressed patients were excluded from the vaccine licensing trials, additional data regarding the safety and efficacy of COVID-19 vaccines are eagerly awaited in these and other subgroups. Remarkably safe and highly effective mRNA COVID-19 vaccines are now available for widespread use and should be given to all adult patients with CLD and LT recipients. The online companion document located at https://www.aasld.org/about-aasld/covid-19-resources will be updated as additional data become available regarding the safety and efficacy of other COVID-19 vaccines in development.

Modeling the Hepatology Workforce in the United States: A Predicted Critical Shortage.

BACKGROUND AND AIMS: Liver disease is prevalent in the United States, and as the population ages, an increasing number of patients are anticipated to present for care. The state of the current hepatology workforce and future demand for hepatology providers is not known. The aim of this study was to model future projections for hepatology workforce demand. APPROACH AND RESULTS: A workforce study of hepatology providers in the United States was completed using primary and secondary data sources. An integrated workforce framework model was used that combined socioeconomic factors that drive economic demand, epidemiological factors that drive need, and utilization rates of health care services. Supply and demand projections were calculated for adult and pediatric hepatology professionals. Sensitivity analyses were conducted to cover the feasible range of these assumptions. An electronic survey of American Association for the Study of Liver Diseases (AASLD) members whose practice included 50% or more hepatology was conducted. In 2018, the adult and pediatric workforce included 7,296 and 824 hepatology providers, respectively, composed of hepatologists, gastroenterologists, and advanced practice providers whose practice was ≥50% hepatology. The modeling analysis projects that in 2023, 2028, and 2033, there will be shortages of 10%, 23%, and 35% adult hepatology providers, respectively, and 19%, 20%, and 16% pediatric hepatology providers, respectively. In sensitivity analyses, a shortage of hepatology providers is predicted even under optimistic assumptions. Among the respondents to the survey, the median age was higher among gastroenterologists and general hepatologists compared with transplant hepatologists. The most common category treated by transplant hepatologists was general hepatology. CONCLUSIONS: There is an impending critical shortage of adult and pediatric hepatology providers. Strategies are needed to encourage clinicians to pursue hepatology, especially in areas outside of transplant centers.

Clinical Research in Hepatology in the COVID-19 Pandemic and Post-Pandemic Era: Challenges and the Need for Innovation.

The severe acute respiratory syndrome coronavirus 2 pandemic has drastically altered all facets of clinical care and research. Clinical research in hepatology has had a rich tradition in several domains, including the discovery and therapeutic development for diseases such as hepatitis B and C and studying the natural history of many forms of chronic liver disease. National Institutes of Health, foundation, and industry funding have provided important opportunities to advance the academic careers of young investigators while they strived to make contributions to the field. Instantaneously, however, all nonessential research activities were halted when the pandemic started, forcing those involved in clinical research to rethink their research strategy, including a shift to coronavirus disease 2019 research while endeavoring to maintain their preexisting agenda. Strategies to maintain the integrity of ongoing studies, including patient follow-up, safety assessments, and continuation of investigational products, have included a shift to telemedicine, remote safety laboratory monitoring, and shipping of investigational products to study subjects. As a revamp of research is being planned, unique issues that face the research community include maintenance of infrastructure, funding, completion of studies in the predetermined time frame, and the need to reprogram career path timelines. Real-world databases, biomarker and long-term follow up studies, and research involving special groups (children, the homeless, and other marginalized populations) are likely to face unique challenges. The implementation of telemedicine has been dramatically accelerated and will serve as a backbone for the future of clinical research. As we move forward, innovation in clinical trial design will be essential for conducting optimized clinical research.

Clinical Best Practice Advice for Hepatology and Liver Transplant Providers During the COVID-19 Pandemic: AASLD Expert Panel Consensus Statement.

BACKGROUND AND AIMS: Coronavirus disease 2019 (COVID-19), the illness caused by the SARS-CoV-2 virus, is rapidly spreading throughout the world. Hospitals and healthcare providers are preparing for the anticipated surge in critically ill patients, but few are wholly equipped to manage this new disease. The goals of this document are to provide data on what is currently known about COVID-19, and how it may impact hepatologists and liver transplant providers and their patients. Our aim is to provide a template for the development of clinical recommendations and policies to mitigate the impact of the COVID-19 pandemic on liver patients and healthcare providers. APPROACH AND RESULTS: This article discusses what is known about COVID-19 with a focus on its impact on hepatologists, liver transplant providers, patients with liver disease, and liver transplant recipients. We provide clinicians with guidance for how to minimize the impact of the COVID-19 pandemic on their patients' care. CONCLUSIONS: The situation is evolving rapidly, and these recommendations will need to evolve as well. As we learn more about how the COVID-19 pandemic impacts the care of patients with liver disease, we will update the online document available at https://www.aasld.org/about-aasld/covid-19-and-liver.
