Access to robotic assisted kidney transplant for recipients: a systematic review and call for reporting standards.

Robot-assisted kidney transplantation (RAKT) is a relatively novel, minimally invasive option for kidney transplantation. However, clarity on recipient selection in the published literature is lacking thereby significantly limiting interpretation of safety and other outcomes. This systematic review aimed to identify and synthesize the data on selection of RAKT recipients, compare the synthesized data to kidney transplant recipients across the USA, and explore geographical clusters of availability of RAKT. Systematic literature review, in accordance with PRISMA, via OVID MEDLINE, Embase, and Web of science from inception to March 5, 2023. All data entry double blinded and quality via Newcastle Ottawa Scale. 44 full-text articles included, encompassing approximately 2402 kidney transplant recipients at baseline but with considerable suspicion for overlap across publications. There were significant omissions of information across studies on patient selection for RAKT and/or analysis. Overall, the quality of studies was very low. Given suspicion of overlap across studies, it is difficult to determine how many RAKT recipients received living (LD) versus deceased donor (DD) organs, but a rough estimate suggests 89% received LD. While the current RAKT literature provides preliminary evidence on safety, there are significant omissions in reporting on patient selection for RAKT which limits interpretation of findings. Two recommendations: (1) international consensus is needed for reporting guidelines when publishing RAKT data and (2) larger controlled trials consistently reporting recipient characteristics are needed to clearly determine selection, safety, and outcomes across both LD and DD recipients.

Generating strategies for a national comeback in pancreas transplantation: A Delphi survey and US conference report.

In the United States, potential transplant candidates with insulin-dependent diabetes mellitus are inconsistently offered pancreas transplantation (PTx), contributing to a dramatic decline in pancreas allograft utilization over the past 2 decades. The American Society of Transplantation organized a workshop to identify barriers inhibiting PTx and to develop strategies for a national comeback. The 2-day workshop focused on 4 main topics: (1) referral/candidate selection, (2) organ recovery/utilization, (3) program performance/patient outcomes, and (4) enhanced education/research. Topics were explored through expert presentations, patient testimonials, breakout sessions, and strategic planning, including the identification of tasks for immediate focus. Additionally, a modified-Delphi survey was conducted among workshop members to develop and rate the importance of barriers, and the impact and feasibility of workgroup-identified improvement strategies. The panelists identified 16 barriers to progress and 44 strategies for consideration. The steps for a national comeback in PTx involve greater emphasis on efficient referral and candidate selection, better donor pancreas utilization practices, eliminating financial barriers to procurement and transplant, improving collaboration between transplant and diabetes societies and professionals, and increasing focus on PTx training, education, and research. Partnership between national societies, patient advocacy groups, and professionals will be essential to realizing this critical agenda.

Lessons learned: Development of an organ transplant caregiver educational resource.

BACKGROUND: Organ transplant lay caregivers perform an essential and complex role, but there is a paucity of comprehensive, accessible education regarding transplant caregiving. We sought to create a broad, multifaceted educational toolkit for transplant caregivers. Given the complexities of this population, we report on lessons learned by organising diverse stakeholder engagement to develop an educational resource covering the breadth and depth of organ transplantation. APPROACH: Following a call from organ transplant patients and caregivers, the American Society of Transplantation (AST) formed an Organ Transplant Caregiver Initiative with the aim to develop a comprehensive educational toolkit for transplant caregivers. The AST Organ Transplant Caregiver Toolkit was created through a shared, multi-step process involving transplant professionals and caregivers, who formed an education subcommittee to develop and refine content domains. The caregiver toolkit was reviewed with relevant external stakeholders and through an internal organisational review process. EVALUATION: Lessons learned included seeking guidance from others with experience creating similar resources, flexibility in project development, creativity in engaging stakeholders and routine communication between all entities involved. Insights gained contributed to the caregiver toolkit completion despite project challenges. IMPLICATIONS: The AST Organ Transplant Caregiver Toolkit can be utilised by health care professionals to educate and counsel transplant patients and caregivers. Lessons learned from the development of the caregiver toolkit can provide guidance to health care professionals and clinical teachers for the development of future education resources.

Full-thickness resection device for management of lesions involving the appendiceal orifice: Systematic review and meta-analysis.

Background and study aims Endoscopic resection of lesions involving the appendiceal orifice is technically challenging and is commonly referred for surgical resection. However, post-resection appendicitis is a concern. Many studies have varying rates of post-procedure appendicitis. We aim to report the rate of post-resection appendicitis by performing a systematic review and meta-analysis. Methods Studies that involved the use of a full-thickness resection device (FTRD) for management of appendiceal polyps were included. The primary outcome was appendicitis after FTRD and a subgroup analysis was performed on studies that only included FTRD performed at the appendiceal orifice. Results Appendicitis was encountered in 15% (95%CI: [11-21]) of the patients with 61% (95% CI: [44-76]) requiring surgical management. Pooled rates of technical success, histologic FTR, and histologic R0 resection in this sub-group (n=123) were 92% (95% CI: [85-96]), 98% (95% CI: [93-100]), and 72% (95% CI: [64-84%]), respectively. Post-resection histopathological evaluation revealed a mean resected specimen size of 16.8 ± 5.4 mm, with non-neoplastic pathology in 9 (7%), adenomas in 103 (84%), adenomas + high-grade dysplasia (HGD) in nine (7%), and adenocarcinoma in two (2%). The pooled rate for non-appendicitis-related surgical management (technical failure and/or high-risk lesions) was 11 % (CI: 7-17). Conclusions FTRD appears to be an effective method for managing appendiceal lesions. However, appendicitis post-resection occurs in a non-trivial number of patients and the R0 resection rate in appendiceal lesions is only 72%. Therefore, caution should be employed in the use of this technique, considering the relative risks of surgical intervention in each patient.

Measuring disparities in virtual healthcare and outcomes in chronic obstructive pulmonary disease patients during the COVID-19 pandemic.

INTRODUCTION: The use of virtual healthcare increased with the COVID-19 pandemic, even among chronic obstructive pulmonary disease (COPD) patients. We measured disparities in virtual compared to traditional healthcare and outcomes in COPD patients during the pandemic. METHODS: This study retrospectively identified adult patients with virtual or in-person primary care encounters at a large, Midwestern hospital system between March 1, 2020, and June 30, 2020. Data regarding age, sex, race, smoking, area deprivation index (ADI), COPD diagnosis, visit type (office, telephone, video, E-visit, virtual, or hybrid of office and virtual), and time to hospital admission in the following 12 months were collected. Analysis was performed using chi-square, analysis of variance, Kruskal-Wallis rank sum, and Cox proportional modeling. RESULTS: This study identified 86,715 patients. Of those, 4702 had COPD and were more likely to be 65 years or older, White, have higher ADI, use telephone or hybrid visits compared to the rest of the study population and majority had smoking history. Office, telephone, and hybrid visits were used frequently, consistently seen across sex, race, ADI, and smoking categories. Increasing age was associated with increased use of office and telephone visits, and decreased use of video visits. Higher ADI was associated with telephone visits, and lower ADI was associated with video visits. There were no significant differences in overall, COPD, or COVID-19 hospital admission rates across visit types. DISCUSSION: Complex disparities in utilizing traditional healthcare are also reflected in virtual healthcare in COPD patients, and do not significantly affect hospital admissions.

Disparities in Referrals to End-of-Life Care in Eligible Hepatocellular Carcinoma Patients.

BACKGROUND: Hepatocellular Carcinoma (HCC) is a malignancy with increasing incidence and morbidity. For patients with a poor prognosis, engagement with advanced care planning and end-of life (EOL) services (I.e., palliative care, hospice) can address physical, financial, and social complications of a terminal diagnosis. Minimal data exist on the demographics of the patients being referred to and enrolling in EOL services for HCC. AIMS: We aim to report the relationship between demographics and EOL service referral. METHODS: Retrospective review of a prospectively maintained high-volume liver center registry of patients diagnosed with HCC from 2004 to 2022. EOL services eligible patients were defined as BCLC stage C or D, evidence of metastases, and/or transplant ineligible. RESULTS: Black patients were more likely to be referred than white patients (OR 1.47 (1.03, 2.11)). Once referred, patients were significantly more likely to be enrolled if they had insurance coverage, though no other factors in models were significant. There were no significant differences in survival among those referred who did or did not enroll, after controlling for other factors. CONCLUSION: Black patients were more likely to be referred compared to white patients and patients who were insured were more likely to be enrolled. Whether this is indicative of black patients being appropriately referred at a higher rate, being offered EOL care instead of aggressive treatment, or other unknown factors warrants further study.

Advances and innovations in living donor liver transplant techniques, matching and surgical training: Meeting report from the living donor liver transplant consensus conference.

The practice of LDLT currently delivers limited impact in western transplant centers. The American Society of Transplantation organized a virtual consensus conference in October 2021 to identify barriers and gaps to LDLT growth, and to provide evidence-based recommendations to foster safe expansion of LDLT in the United States. This article reports the findings and recommendations regarding innovations and advances in approaches to donor-recipient matching challenges, the technical aspects of the donor and recipient operations, and surgical training. Among these themes, the barriers deemed most influential/detrimental to LDLT expansion in the United States included: (1) prohibitive issues related to donor age, graft size, insufficient donor remnant, and ABO incompatibility; (2) lack of acknowledgment and awareness of the excellent outcomes and benefits of LDLT; (3) ambiguous messaging regarding LDLT to patients and hospital leadership; and (4) a limited number of proficient LDLT surgeons across the United States. Donor-recipient mismatching may be circumvented by way of liver paired exchange. The creation of a national registry to generate granular data on donor-recipient matching will guide the practice of liver paired exchange. The surgical challenges to LDLT are addressed herein and focuses on the development of robust training pathways resulting in proficiency in donor and recipient surgery. Utilizing strong mentorship/collaboration programs with novel training practices under the auspices of established training and certification bodies will add to the breadth and depth of training.

Financial, policy, and ethical barriers to the expansion of living donor liver transplant: Meeting report from a living donor liver transplant consensus conference.

INTRODUCTION: In October 2021, the American Society of Transplantation (AST) hosted a virtual consensus conference aimed at identifying and addressing barriers to the broader, safe expansion of living donor liver transplantation (LDLT) throughout the United States (US). METHODS: A multidisciplinary group of LDLT experts convened to address issues related to financial implications on the donor, transplant center crisis management, regulatory and oversight policies, and ethical considerations by assessing the relative significance of issues in preventing LDLT growth, with proposed strategies to overcome barriers. RESULTS: Living liver donors endure multiple obstacles including financial instability, loss of job security, and potential morbidity. These concerns, along with other center, state, and federal specific policies can be perceived as significant barriers to expanding LDLT. Donor safety is of paramount importance to the transplant community; however, regulatory and oversight policies aimed at ensuring donor safety can be viewed as ambiguous and complicated leading to time-consuming evaluations that may deter donor motivation and program expansion. CONCLUSION: Transplant programs need to establish appropriate crisis management plans to mitigate potential negative donor outcomes and ensure program viability and stability. Finally, ethical aspects, including informed consent for high-risk recipients and use of non-directed donors, can be perceived as additional barriers to expanding LDLT.

A survey of transplant providers regarding attitudes, barriers, and facilitators to living donor liver transplantation in the United States.

INTRODUCTION: A successful living donor liver transplant (LDLT) is the culmination of a multifaceted process coordinated among key stakeholders. METHODS: We conducted an electronic survey of US liver transplant (LT) centers (August 26, 2021-October 10, 2021) regarding attitudes, barriers, and facilitators of LDLT to learn how to expand LDLT safely and effectively in preparation for the American Society of Transplantation Living Donor Liver Transplant Consensus Conference. RESULTS: Responses were received from staff at 58 programs (40.1% of US LT centers). There is interest in broadening LDLT (100% of LDLT centers, 66.7% of non-LDLT centers) with high level of agreement that LDLT mitigates donor shortage (93.3% of respondents) and that it should be offered to all suitable candidates (87.5% of respondents), though LDLT was less often endorsed as the best first option (29.5% of respondents). Key barriers at non-LDLT centers were institutional factors and surgical expertise, whereas those at LDLT centers focused on waitlist candidate and donor factors. Heterogeneity in candidate selection for LDLT, candidate reluctance to pursue LDLT, high donor exclusion rate, and disparities in access were important barriers. CONCLUSION: Findings from this study may help guide current and future expansion of LDLT more efficiently in the US. These efforts require clear and cohesive messaging regarding LDLT benefits, engagement of the public community, and dedicated resources to equitably increase LDLT access.

Living donor liver transplantation: A multi-disciplinary collaboration towards growth, consensus, and a change in culture.

INTRODUCTION: Living donor liver transplantation (LDLT) reduces liver transplant waitlist mortality and provides excellent long-term outcomes for persons with end stage liver disease. Yet, utilization of LDLT has been limited in the United States (US). METHODS: In October 2021, the American Society of Transplantation held a consensus conference to identify important barriers to broader expansion of LDLT in the US, including data gaps, and make recommendations for impactful and feasible mitigation strategies to overcome these barriers. Domains addressed encompassed the entirety of the LDLT process. Representation from international centers and living donor kidney transplantation were included for their perspective/experience in addition to members across disciplines within the US liver transplantation community. A modified Delphi approach was employed as the consensus methodology. RESULTS: The predominant theme permeating discussion and polling results centered on culture; the beliefs and behaviors of a group of people perpetuated over time. CONCLUSIONS: Creating a culture of support for LDLT in the US is key for expansion and includes engagement and education of stakeholders across the spectrum of the process of LDLT. A shift from awareness of LDLT to acknowledgement of benefit of LDLT is the primary goal. Propagation of the maxim "LDLT is the best option" is pivotal.

Living donor liver transplant candidate and donor selection and engagement: Meeting report from the living donor liver transplant consensus conference.

INTRODUCTION: Living donor liver transplantation (LDLT) is a promising option for mitigating the deceased donor organ shortage and reducing waitlist mortality. Despite excellent outcomes and data supporting expanding candidate indications for LDLT, broader uptake throughout the United States has yet to occur. METHODS: In response to this, the American Society of Transplantation hosted a virtual consensus conference (October 18-19, 2021), bringing together relevant experts with the aim of identifying barriers to broader implementation and making recommendations regarding strategies to address these barriers. In this report, we summarize the findings relevant to the selection and engagement of both the LDLT candidate and living donor. Utilizing a modified Delphi approach, barrier and strategy statements were developed, refined, and voted on for overall barrier importance and potential impact and feasibility of the strategy to address said barrier. RESULTS: Barriers identified fell into three general categories: 1) awareness, acceptance, and engagement across patients (potential candidates and donors), providers, and institutions, 2) data gaps and lack of standardization in candidate and donor selection, and 3) data gaps regarding post-living liver donation outcomes and resource needs. CONCLUSIONS: Strategies to address barriers included efforts toward education and engagement across populations, rigorous and collaborative research, and institutional commitment and resources.

Disparities in Use of Virtual Primary Care During the Early COVID-19 Pandemic.

Background: The COVID-19 pandemic increased the use of virtual health care. However, certain factors may disparately affect some patients' utilization of virtual care. Associations between age, racial categories (White or Black), and socioeconomic disadvantage were evaluated during the early COVID-19 pandemic. Methods: This cross-sectional retrospective study included adult patients with virtual or in-person primary care encounters at a large, midwestern hospital system with widespread urban and suburban offices between March 1, 2020, and June 30, 2020. Virtual visits included synchronous video and telephone visits and asynchronous patient portal E-visits. Chi-squared tests and multivariable logistic analysis assessed the associations between ages and racial categories, and area deprivation index with the use of virtual versus in-person primary care. Results: Of 72,153 patient encounters, 43.0% were virtual visits, 54.6% were White patients, and 45.4% were Black. Across equivalent age ranges, black patients were slightly less likely to utilize virtual care than similarly aged White patients, but not consistently across virtual modalities. Women were more likely to use virtual care across all modalities, and individuals >65 years were more likely to use telephone visits and less likely to use video and E-visits, regardless of race. Patients residing in areas with the greatest socioeconomic advantage were more likely to utilize video and E-visits. Conclusions: Differential patterns of utilization emerged across racial categories and age ranges, suggesting that racial disparities are exacerbated depending upon patient age and mode of utilization.

A viewpoint describing the American Society of Transplantation rationale to conduct a comprehensive patient survey assessing unmet immunosuppressive therapy needs.

This viewpoint aims to "set the stage" and provide the rationale for the proposed development of a large-scale, comprehensive survey assessing transplant patients' perceived unmet immunosuppressive therapy needs. Research in organ transplantation has historically focused on reducing the incidence and impact of rejection on allograft survival and minimizing or eliminating the need for chronic immunosuppressive therapies. There has been less emphasis and investment in therapies to improve patient-reported outcomes including health-related quality of life and side-effects. Patient-focused drug development (PFDD) is a new and important emphasis of the Food and Drug Administration (FDA) that provides a guiding philosophy for incorporating the patient experience into drug development and evaluation. The American Society of Transplantation (AST) Board of Directors commissioned this working group to prepare for the conduct of a comprehensive patient survey assessing unmet immunosuppressive therapy needs. This paper aims to describe the basis for why it is important to conduct this survey and briefly outline the plan for broad stakeholder engagement to ensure the information gained is diverse, inclusive, and relevant for advancing PFDD in organ transplant recipients.

Current recommendations regarding evaluation of cognitive functioning in organ transplant candidates.

PURPOSE OF REVIEW: Cognitive impairment is associated with negative effects on solid organ transplant candidates, recipients, and their care partners. However, because of the heterogeneity of mechanisms, presentations, and assessment measures, research suggests a wide array of impairments, patterns of impairments, and unclear trajectories posttransplant. This review provides an abbreviated synthesis of recent research on cognitive impairments observed in organ-eligible candidates and potential trajectories through posttransplant, current clinical recommendations regarding integration of assessment into routine clinical transplant practice, as well as recommendations for future research. RECENT FINDINGS: Transplantation may resolve certain disease-contributing factors to cognitive impairments but also introduces new potential neurocognitive assaults. Recent studies in kidney and lung recipients document continued impairments in subsets of patients, particularly those identified as frail. For liver candidates, new assessment measures of hepatic encephalopathy have been developed and preliminarily tested with potential for translation into routine clinical care. Clinical implications, as well as ethical considerations are discussed. SUMMARY: Although guidelines agree that cognitive assessment is an important part of the organ transplantation process, many questions remain of how to best assess cognition and intervene when cognitive impairment is identified in transplant populations. Further research should focus on prospective, longitudinal assessments in transplant-eligible populations through posttransplant.

Heterogeneity in Center Practices in Liver Transplantation for Alcohol-Associated Liver Disease in the United States.

INTRODUCTION: Alcohol-related liver disease (ALD) is now the leading indication for liver transplantation (LT) in the United States (US). It remains unclear how centers are managing the medical and psychosocial issues associated with these patients. METHODS: We conducted a web-based survey of LT centers in the United States to identify center-level details on peri-LT management of ALD and related issues. RESULTS: Of the 117 adult LT centers, 100 responses (85.5%) were collected, representing all Organ Procurement and Transplantation Network regions. For alcohol-associated cirrhosis, 70.0% of the centers reported no minimum sobriety requirement while 21.0% required 6 months of sobriety. LT for severe alcohol-associated hepatitis was performed at 85.0% of the centers. Monitoring protocols for pre-LT and post-LT alcohol use varied among centers. DISCUSSION: Our findings highlight a change in center attitudes toward LT for ALD, particularly for severe alcohol-associated hepatitis.

Substance use screening in transplant populations: Recommendations from a consensus workgroup.

Transplant patients are frequently treated with substances that have dependence potential and/or they may have a history of substance use disorders. The Psychosocial and Ethics Community of Practice of the American Society of Transplantation formed a Drug Testing Workgroup with participation from members of the Pharmacy Community of Practice and members of the Academy of Consultation-Liaison Psychiatry. The workgroup reviewed the literature regarding the following issues: the role of drug testing in patients with substance use disorders, for patients prescribed controlled substances, legal, ethical and prescription drug monitoring issues, financial and insurance issues, and which patients should be tested. We also reviewed current laboratory testing for substances. Group discussions to develop a consensus occurred, and summaries of each topic were reviewed. The workgroup recommends that transplant patients be informed of drug testing and be screened for substances prior to transplant to ensure optimal care and implement ongoing testing if warranted by clinical history. While use of certain substances may not result in the exclusion for transplantation, an awareness of the patient's practices and possible risk from substances is necessary, allowing transplant teams to screen for substance use disorders and ensure the patient is able to manage and minimize risks post-transplant.

Non-pharmacological interventions engaging organ transplant caregivers: A systematic review.

INTRODUCTION: Lay-caregivers in organ transplantation (to candidates, recipients, and donors) are essential to pre- and postoperative care, but report significant caregiving-related stressors. This review aims to summarize studies testing nonpharmacological interventions aimed at improving organ transplant caregiver-reported outcomes. METHODS: In accordance with PRISMA, we conducted a systematic review (searched PubMed, Embase, Cochrane Central, PsycInfo, and CINAHL, no start-date restriction through 7/1/2021). Quality of comparative studies assessed by ROBS-2 or ROBINS. RESULTS: Twelve studies met inclusion. Study designs, interventions, and outcomes varied. Sample sizes were small across caregivers to adults (nine studies, five with caregiver samples ns≤50) and pediatric patients (three studies, caregiver samples ns≤16). Study designs included seven single-arm interventions, two prepost with comparison cohorts, and three randomized-controlled trials. Eight studies included transplant-specific education as the intervention, an interventional component, or as the comparison group. Outcomes included transplant specific knowledge, mental health, and intervention acceptability. Of the nine prepost caregiver assessments and/or comparison groups, four studies demonstrated no statistically significant intervention effects. CONCLUSION: Few interventions addressing the needs of organ transplant caregivers have been empirically evaluated. Existing interventions were well-received by caregivers. Given complexities of care in transplantation, research is needed evaluating interventions using rigorous trial methodology with adequate samples.

Prerenal Transplant Education and Evaluation Positively Impacts Outcomes.

Introduction: An outstanding question in kidney transplantation is how to prepare candidates and their social supports for optimal posttransplant outcomes. Project Aims: This program evaluation assessed whether a pretransplant quality improvement clinic improved clinical outcomes in the year posttransplant compared to recipients receiving standard of care. Design: The Countdown to Transplant Clinic was implemented with kidney transplant candidates expected to receive a transplant within the next few months. The clinic included an enhanced education session on posttransplant lifestyle management, confirmation of support (≥2 adults), and evaluations by transplant social work, psychology, and nephrology. Results: Seventy-five patients participated in the clinic and underwent a transplant. A retrospective chart review of posttransplant laboratory values, rehospitalizations (within 3-months posttransplant), biopsy-confirmed graft failure, and mortality (within 1-year posttransplant) were collected from both groups. Univariate and multivariate propensity score-weighted linear or logistic regression models were used to evaluate the association between clinic participation and outcomes. In models adjusting for relevant covariates, participation in The Countdown to Transplant Clinic (vs standard care) was associated with a lower coefficient of variation of serum tacrolimus (all values collected 3-12 months posttransplant), 30-day posttransplant white blood cell counts (but not 90-day), 90-day posttransplant potassium, and 30 and 31 to 90 days rehospitalizations. Clinic participation did not predict serum glucose levels at 30- or 90-days posttransplant. Due to low rates of rejection and mortality, meaningful comparisons were not possible. Conclusion: Participation in a pretransplant, multicomponent clinic may improve certain outcomes of interest posttransplantation. Pilot testing for feasibility for randomized controlled trials is a necessary next step.
