Kidney transplant candidates' perspectives on the implementation of a Canadian Willingness to Cross program: A strategy to increase access to kidney transplantation for highly sensitized patients.

BACKGROUND: Kidney transplantation is the optimal treatment for end-stage renal disease. However, highly sensitized patients (HSPs) have reduced access to transplantation, leading to increased morbidity and mortality on the waiting list. The Canadian Willingness to Cross (WTC) program proposes allowing transplantation across preformed donor specific antibodies (DSA) determined to be at a low risk of rejection under the adaptive design framework. This study collected patients' perspectives on the development of this program. METHODS: Forty-one individual interviews were conducted with kidney transplant candidates from three Canadian transplant centers in 2022. The interviews were digitally recorded and transcribed for subsequent analyses. RESULTS: Despite limited familiarity with the adaptive design, participants demonstrated trust in the researchers. They perceived the WTC program as a pathway for HSPs to access transplantation while mitigating transplant-related risks. HSPs saw the WTC program as a source of hope and an opportunity to leave dialysis, despite acknowledging inherent uncertainties. Some non-HSPs expressed concerns about fairness, anticipating increased waiting times and potential compromise in kidney graft longevity due to higher rejection risks. Participants recommended essential strategies for implementing the WTC program, including organizing informational meetings and highlighting the necessity for psychosocial support. CONCLUSION: The WTC program emerges as a promising strategy to enhance HSPs' access to kidney transplantation. While HSPs perceived this program as a source of hope, non-HSPs voiced concerns about distributive justice issues. These results will help develop a WTC program that is ethically sound for transplant candidates.

Living ethics: a stance and its implications in health ethics.

Moral or ethical questions are vital because they affect our daily lives: what is the best choice we can make, the best action to take in a given situation, and ultimately, the best way to live our lives? Health ethics has contributed to moving ethics toward a more experience-based and user-oriented theoretical and methodological stance but remains in our practice an incomplete lever for human development and flourishing. This context led us to envision and develop the stance of a "living ethics", described in this inaugural collective and programmatic paper as an effort to consolidate creative collaboration between a wide array of stakeholders. We engaged in a participatory discussion and collective writing process known as instrumentalist concept analysis. This process included initial local consultations, an exploratory literature review, the constitution of a working group of 21 co-authors, and 8 workshops supporting a collaborative thinking and writing process. First, a living ethics designates a stance attentive to human experience and the role played by morality in human existence. Second, a living ethics represents an ongoing effort to interrogate and scrutinize our moral experiences to facilitate adaptation of people and contexts. It promotes the active and inclusive engagement of both individuals and communities in envisioning and enacting scenarios which correspond to their flourishing as authentic ethical agents. Living ethics encourages meaningful participation of stakeholders because moral questions touch deeply upon who we are and who we want to be. We explain various aspects of a living ethics stance, including its theoretical, methodological, and practical implications as well as some barriers to its enactment based on the reflections resulting from the collaborative thinking and writing process.

Kidney transplant candidates' and recipients' perspectives on the decision-making process to accept or refuse a deceased donor kidney offer: Trust and graft survival matter.

BACKGROUND: The decision to accept a kidney from a deceased donor can be a difficult one. This study aims to capture the perspectives of transplant candidates (TCs) and kidney transplant recipients (KTRs) on the decision-making process when a deceased kidney is offered. METHODS: We conducted six focus groups with KTRs and TCs. The content of the focus groups was analyzed using the qualitative thematic method. RESULTS: KTRs reported that the experience of being offered a kidney could be difficult because of the circumstances of the offer and unpreparedness to participate in the discussion. Both KTRs and TCs trusted the medical expertise. Age and having experience with dialysis could influence the decision to accept an offer. In order to engage in the discussion, patients wanted to obtain estimates of expected graft survival. Patients did not express interest for a web-based calculator for patient use, but expected transplant physicians to summarize and explain the information that would impact graft survival time. CONCLUSION: TCs and KTRs wanted to be involved in the decision to accept a deceased donor kidney. Tools that can help physicians communicate the risks and benefits of accepting an offer could improve patient participation in the decision-making process.

Québec health care professionals' perspectives on organ donation after medical assistance in dying.

BACKGROUND: Medical assistance in dying (MAID) has been legal in Québec since December 2015 and in the rest of Canada since July 2016. Since then, more than 60 people have donated their organs after MAID. Such donations raise ethical issues about respect of patients' autonomy, potential pressure to choose MAID, the information given to potential donors, the acceptability of directed donations in such a context and the possibility of death by donation. The objective of this study was to explore Québec professionals' perspectives on the ethical issues related to organ donation after MAID. METHODS: We conducted semi-directed interviews with 21 health care professionals involved in organ donation such as intensivists and intensive care nurses, operating room nurses, organ donation nurses and coordinators. RESULTS: The participants were all favourable to organ donation after MAID in order to respect patients' autonomy. They also favoured informing all potential donors of the possibility of donating organs. They highlighted the importance of assessing donors' reasons for requesting MAID during the assessment. They were divided on directed donation, living donation before MAID and death by donation. CONCLUSION: Organ donation after MAID was widely accepted among the participants, based on the principle of respect for the donor's autonomy. The findings of this study only provide the perspectives of Québec health care professionals involved in organ donation. Future studies are needed to gather other stakeholders' perspectives on this issue as well as patients' and families' experiences of organ donation after MAID.

The COVID-19 pandemic and organ donation and transplantation: ethical issues.

BACKGROUND: The COVID-19 pandemic has had a significant impact on the health system worldwide. The organ and tissue donation and transplantation (OTDT) system is no exception and has had to face ethical challenges related to the pandemic, such as risks of infection and resource allocation. In this setting, many Canadian transplant programs halted their activities during the first wave of the pandemic. METHOD: To inform future ethical guidelines related to the COVID-19 pandemic or other public health emergencies of international concern, we conducted a literature review to summarize the ethical issues. RESULTS: This literature review identified three categories of ethical challenges. The first one describes the general ethical issues and challenges reported by OTDT organizations and transplantation programs, such as risks of COVID-19 transmission and infection to transplant recipients and healthcare professionals during the transplant process, risk of patient waitlist mortality or further resource strain where transplant procedures have been delayed or halted, and resource allocation. The second category describes ethical challenges related to informed consent in the context of uncertainty and virtual consent. Finally, the third category describes ethical issues related to organ allocation, such as social considerations in selecting transplant candidates. CONCLUSION: This literature review highlights the salient ethical issues related to OTDT during the current COVID-19 pandemic. As medical and scientific knowledge about COVID-19 increases, the uncertainties related to this disease will decrease and the associated ethical issues will continue to evolve.

Canadian transplant nephrologists' perspectives on the decision-making process for accepting or refusing a kidney from a deceased organ donor.

BACKGROUND: Kidney transplantation is the best treatment for patients with end-stage renal disease. The decision to accept a kidney from a deceased donor can be a difficult one, especially when organs from high KDPI (>85%) donors are offered. This study aims to capture the perspectives of transplant nephrologists (TNs) on the decision-making process when an organ is offered. METHODS: Fifteen Canadian TNs took part in semi-structured interviews between December 2017 and April 2018. The interviews were digitally recorded, transcribed, and analyzed using the thematic analysis method. RESULTS: The decision to accept a deceased-donor kidney offer is a medical one for the participants. However, transplant candidates could be involved when the offered kidney is from a donor with a KDPI >85% or increased infectious risk donor. The TNs' past experience, comprehensive data on the donor, and education of the transplant candidate could facilitate the decision-making process. A decision aid could also facilitate the decision-making process, but different concerns should be addressed. CONCLUSION: Although accepting a deceased-donor organ offer is often viewed as an opportunity for shared decision-making, participants in this study viewed the decision to accept or refuse an offer as a medical decision with little room for patient participation.

Engaging family partners in deceased organ donation research-a reflection on one team's experience.

PURPOSE: Clinical researchers are now encouraged to include patient partners in all research projects. Nevertheless, published accounts of patient engagement in complex research projects, such as those involving critically ill and dying patients, are lacking. Whether this absence is due to the relatively new emergence of patient engagement research methods or fundamental challenges regarding family engagement in challenging research contexts is unclear. We describe our experiences with forming a researcher-family partnership in a deceased organ donation research project involving the prospective observation of potential and actual deceased organ donors dying in the intensive care unit. METHODS: We used the Guidance for Reporting Involvement of Patients and the Public evidence-based, consensus-informed reporting guidelines to organize our narrative. RESULTS: We were able to initiate and sustain a research consultant relationship with the mother of a deceased organ donor for over two years. Challenges faced included: constraints on money and time, communication preferences, and the emotional stress of participating in difficult conversations. Positive outcomes included: improvement of data collection tools, new opportunities for access to research populations, and motivation to include family partnership in future grant proposals. CONCLUSIONS: Family engagement in deceased organ donation research is feasible and contributes positively to study progress and outcomes. Patient and family engagement in challenging research contexts may require special attention to the emotional challenges of participation. We hope that our experience will encourage clinical researchers working in deceased organ donation and similarly complex domains to consider including patient partners in their projects.

RéSUMé: OBJECTIF: Les cliniciens sont maintenant encouragés à inclure les partenaires des patients dans tous leurs projets de recherche. Néanmoins, on ne dispose d'aucune publication sur la participation des patients et de leur famille dans des projets de recherche complexes tels que ceux impliquant des patients dans un état critique ou mourants. Savoir si cette absence est liée à l'émergence relativement récente des méthodes de recherche sur la participation des patients ou aux défis fondamentaux concernant la participation des familles dans un contexte de recherche difficile reste une question débattue. Nous décrivons nos expériences de la formation d'un partenariat chercheur-famille dans un projet de recherche sur le don d'organe impliquant l'observation prospective de donneurs d'organes potentiels ou décédés, décédant dans une unité de soins intensifs. MéTHODES: Nous utilisons le document intitulé Guidance for Reporting Involvement of Patients (conseils pour rendre compte de l'implication des patients) et les lignes directrices publiques basées sur des données probantes pour la publication fondées sur un consensus, pour organiser notre compte rendu. RéSULTATS: Nous avons pu instaurer et maintenir pendant plus de deux ans une relation de consultant en recherche avec la mère d'un donneur d'organe décédé. Les défis rencontrés étaient notamment les contraintes financières et de temps, les préférences en matière de communications et le stress émotionnel créé par la participation à des conversations sur des sujets difficiles. Les résultats positifs ont été, notamment l'amélioration des outils de collecte de données, les nouvelles possibilités d'accès à des populations de recherche et la motivation à inclure un partenariat avec la famille dans les futures propositions de subventions. CONCLUSIONS: La participation de la famille dans la recherche sur le don d'organe d'une personne décédée est faisable et contribue positivement à l'avancement et à l'aboutissement des études. La participation du patient et de sa famille dans un contexte de recherche difficile peut demander de porter une attention particulière aux défis émotionnels de cette participation. Nous espérons que notre expérience encouragera les cliniciens chercheurs qui travaillent sur le don d'organes de personnes décédées et d'autres domaines aussi complexes à envisager d'inclure les partenaires des patients dans leurs projets.

Web-Based Tailored Nursing Intervention to Support Medication Self-management: A Qualitative Study of the Experience of Kidney Transplant Recipients.

Optimal adherence to immunosuppressive medication is essential to kidney graft success. A Web-based tailored virtual nursing intervention was developed to promote medication adherence and support self-management among kidney transplant recipients. A qualitative study was undertaken in a hospital setting in Montreal (Canada) to document how users experience the intervention and to explore medication intake self-management behaviors. To participate, transplant recipients had to be at least 18 years old and had to have completed at least one computer session of the intervention. Semistructured interviews were conducted with 10 participants (two women, eight men) with a mean age of 47.8 years. They reported receiving their latest renal transplant on average 10.6 years prior. Content analysis of the interview transcripts yielded five major themes: (1) kidney transplant is a gift from life; (2) routinization of medication intake; (3) intervention is a new and positive experience; (4) using the intervention offers many benefits; and (5) individual relevance of the intervention. Patient experience shows the intervention is acceptable and can help better manage medication intake. Results also underscore the importance of offering the intervention early in the care trajectory of transplant recipients. Web-based tailored virtual nursing interventions could constitute an easily available adjunct to existing specialized services.

Stabilization of renal function after the first year of follow-up in kidney transplant recipients treated for significant BK polyomavirus infection or BK polyomavirus-associated nephropathy.

BACKGROUND: BK polyomavirus virus (BKPyV) screening and immunosuppression reduction effectively prevent graft loss due to BKPyV-associated nephropathy (BKPVAN) during the first year after transplantation. The aim of our study was to evaluate the impact of this infection during longer follow-up periods. METHODS: We reviewed the outcome of our screening and immunosuppression reduction protocol in 305 patients who received a kidney transplant between March 2008 and January 2013. Quantitative BKPyV DNA surveillance in plasma was performed at 1, 2, 3, 6, 9, and 12 months after transplantation. Patients with significant viremia and/or biopsy-proven BKPVAN were treated with immunosuppression reduction and leflunomide. RESULTS: During the first post-transplant year, 24 patients (7.9%) developed significant viremia at a median time of 95 days, and 18 patients had BKPVAN; 23 of the 24 (7.5%) were treated according to our protocol (group BKV+); 225 patients (73.8%) did not develop any BK viremia (group BKV-). Allograft function was similar in both groups at 1 month post transplantation (P=.87), but significantly worse at 1 year in the BKV+ group (P=.002). Thereafter, kidney function stabilized in the BKV+ group and no differences in patient and graft survival were seen between the groups after a median follow-up of 4 years. CONCLUSIONS: We confirm the early occurrence of BKPyV replication after transplantation and the short-term decline in renal function. However, early detection of BKPyV replication, prompt diagnosis, and reduction in immunosuppression may offer long-term benefits for graft function.

Organ donation after medical assistance in dying or cessation of life-sustaining treatment requested by conscious patients: the Canadian context.

In June 2016, following the decision of the Supreme Court of Canada to decriminalise assistance in dying, the Canadian government enacted Bill C-14, legalising medical assistance in dying (MAID). In 2014, the province of Quebec had passed end-of-life care legislation making MAID available as of December 2015. The availability of MAID has many implications, including the possibility of combining this practice with organ donation through the controlled donation after cardiac death (cDCD) protocol. cDCD most often occurs in cases where the patient has a severe neurological injury but does not meet all the criteria for brain death. The donation is subsequent to the decision to withdraw life-sustaining treatment (LST). Cases where patients are conscious prior to the withdrawal of LST are unusual, and have raised doubts as to the acceptability of removing organs from individuals who are not neurologically impaired and who have voluntarily chosen to die. These cases can be compared with likely scenarios in which patients will request both MAID and organ donation. In both instances, patients will be conscious and competent. Organ donation in such contexts raises ethical issues regarding respect for autonomy, societal pressure, conscientious objections and the dead-donor rule. In this article, we look at relevant policies in other countries and examine the ethical issues associated with cDCD in conscious patients who choose to die.

Should we perform kidney transplants on foreign nationals?

In Canada, there are currently no guidelines at either the federal or provincial level regarding the provision of kidney transplantation services to foreign nationals (FN). Renal transplant centres have, in the past, agreed to put refugee claimants and other FNs on the renal transplant waiting list, in part, because these patients (refugee claimants) had health insurance through the Interim Federal Health Programme to cover the costs of medication and hospital care. However, severe cuts recently made to this programme have forced clinicians to question whether they should continue with transplants for FNs, for financial and ethical reasons. This paper first examines different national policies (eg, in Canada, USA, France and the UK) to map the diversity of approaches regarding transplantation for FNs, and then works through different considerations commonly used to support or oppose the provision of organs to these patients: (1) the organ shortage; (2) the free-rider problem; (3) the risk of becoming a transplant destination; (4) the impact on organ donation rates; (5) physicians' duties; (6) economic concerns; (7) vulnerability. Using a Canadian case as a focus, and generalising through a review of various national policies, we analyse the arguments for and against transplantation for FNs with a view to bringing clarity to what is a sensitive political and clinical management issue. Our aim is to help transplant centres, clinicians and ethicists reflect on the merits of possible options, and the rationales behind them.

Canadian Kidney Transplant Professionals' Perspectives on Precision Medicine and Molecular Matching in Kidney Allocation.

Background: Antibody-mediated rejection is an important cause of kidney transplant loss. A new strategy requiring application of precision medicine tools in transplantation considers molecular compatibility between donors and recipients and holds the promise of improved immunologic risk, preventing rejection and premature graft loss. The objective of this study was to gather Canadian transplant professionals' perspectives on molecular compatibility in kidney transplantation. Methods: Seventeen Canadian transplant professionals (14 nephrologists, 2 nurses, and 1 surgeon) participated in semistructured interviews in 2021. The interviews were digitally recorded, transcribed, and analyzed using the qualitative description approach. Results: Participants identified fair access to transplantation as the most important principle in kidney allocation. Molecular compatibility was viewed as a promising innovation. However, participants were concerned about increased waiting times, negative impact on some patients, and potential problems related to the adequacy of information explaining this new technology. To mitigate the challenges associated with molecular matching, participants suggested integrating a maximum waiting time for molecular-matched kidneys and expanding the program nationally/internationally. Conclusions: Molecular matching in kidney transplantation is viewed as a promising technology for decreasing the incidence of antibody-mediated rejection and improving graft survival. Further studies are needed to determine how to ethically integrate this technology into the kidney allocation algorithm.

KEeP ACTIVe Club Study: Kidney Transplant Recipients' Experiences of a Physical Activity and Social Interaction Virtual Group.

Background: It can be difficult for kidney transplant recipients (KTRs) to be physically active after their transplantation. Physical inactivity is a risk factor for cardiovascular disease, one of the leading cause of death among KTRs. To help KTRs start and maintain a physical activity routine, we developed the KEeP ACTIVe Club, a 6-month online intervention with access to a kinesiologist, a patient partner, and a private support group with an online platform (Facebook). Objective: The objective of this study was to capture the participants' experiences of the KEeP ACTIVe Club. Design: Individual interviews. Setting: The Center hospitalier de l'Université de Montréal (CHUM) and the McGill University Health Center (MUHC) kidney transplant programs. Participants: Kidney transplant recipients who participated in the KEeP ACTIVe Club. Methods: Between October and December 2021, we conducted 11 individual semi-directed interviews with KTRs from 2 urban kidney transplant programs who participated in the KEeP ACTIVe Club. The interviews were digitally recorded and transcribed. Thematic analysis was conducted. Results: Participants' principal motivation to participate in the KEeP ACTIVe Club was to improve their physical fitness following their transplant in a pandemic period. One of the main benefits of the KEeP ACTIVe Club was the improvement of participant's self-confidence and the knowledge gained regarding exercises adapted to their reality as KTRs. However, the small number of participants and the schedules of classes offered were viewed as a pitfall of the current intervention. Finally, the peer mentoring and support gained by other participants were important and viewed as highly impactful aspects of the KEeP ACTIVe Club. Limitations: Only 11 of the 18 patients who participated in the KEeP ACTIVe Club took part in the interviews. Conclusion: Participants reported a positive experience with the KEeP ACTIVe Club. Peer mentoring and support gained from other participants seem to be essential aspects of the experience within the KEeP ACTIVe Club. This program is a good avenue to offer in post-transplant care to help KTRs to be more active and to connect with other patients.

Contexte: Il peut être difficile pour les receveurs d'une greffe de rein d'être actifs physiquement après la transplantation. L'inactivité est un facteur de risque de maladie cardiovasculaire, une des principales causes de décès chez les greffés du rein. Afin d'aider ces patients à entreprendre une routine d'activité physique et à la maintenir, nous avons développé le KEeP ACTIVe Club, une intervention en ligne d'une durée de six mois qui donne accès à un kinésiologue, à un patient partenaire et à un groupe privé de soutien par le biais d'une plateforme en ligne (Facebook). Objectifs: Connaître l'expérience des participants au KEeP ACTIVe Club. Conception: Entretiens individuels. Cadre: Les programme de transplantation rénale du Center hospitalier de l'Université de Montréal (CHUM) et du Centre universitaire de santé McGill (CUSM). Participants: Des receveurs d'une greffe de rein ayant participé au KEeP ACTIVe Club. Méthodologie: Entre octobre et décembre 2021, nous avons mené 11 entretiens individuels semi-dirigés avec des receveurs d'une greffe rénale qui ont participé au KEeP ACTIVe Club dans deux programmes de transplantation en center urbain. Les entretiens ont été enregistrés en mode numérique, transcrits, puis une analyze thématique a été réalisée. Résultats: La principale motivation des receveurs à participer au KEeP ACTIVe Club était d'améliorer leur condition physique après la greffe, en période pandémique. Les principaux avantages d'avoir participé au KEeP ACTIVe Club ont été l'augmentation de la confiance en soi et l'acquisition de connaissances sur des exercices adaptés à leur réalité de greffés du rein. Le faible nombre de participants et l'horaire des cours proposés ont été perçus comme des faiblesses de l'intervention. Enfin, le mentorat par les pairs et le soutien reçu des autres participants ont été jugés importants et perçus comme des aspects très positifs du KEeP ACTIVe Club. Limites: Sur les dix-huit patients inscrits au KEeP ACTIVe Club, seuls onze ont participé aux entrevues. Conclusion: Les participants ont déclaré avoir eu une expérience positive avec le KEeP ACTIVe Club. Le mentorat par les pairs et le soutien reçu des autres participants semblent être des aspects essentiels de l'expérience positive vécue au sein du KEeP ACTIVe Club. Ce programme est une bonne avenue à proposer dans les soins post-transplantation pour aider les greffés du rein à être plus actifs physiquement et à échanger avec d'autres patients.

Is it ethical to invite compatible pairs to participate in exchange programmes?

Living kidney transplantation offers the best results for patients with end-stage renal disease (ESRD). This form of transplantation is no longer restricted to genetically or emotionally related donors, as shown by the acceptance of non-directed living anonymous donors, and the development of exchange programmes (EPs). EPs make it possible to perform living kidney transplantation among incompatible pairs, but while such programmes can help increase living organ donation, they can also create a degree of unfairness. Kidney transplant recipients in the O blood group are at a disadvantage when it comes to EPs because they can only receive organs from O donors, whereas O donors are universal donors. This poses a major challenge in terms of distributive justice and equity. A way to remedy this situation is through altruistic unbalanced paired kidney exchange (AUPKE), in which a compatible pair consisting of an O blood group donor and a non-O recipient is invited to participate in an EP. Although the AUPKE approach appears fairer for O recipients, it still raises ethical questions. How does this type of exchange affect the donor/recipient gift relationship? Should recipients in compatible pairs receive a 'better organ' than the one they would otherwise have received from their intended donor? Finally, what is the role of transplant teams in AUPKE? This article will examine the organisational and ethical challenges associated with EPs and AUPKE, and compare different EP policies in countries where such programmes exist.

How is organ transplantation depicted in internal medicine and transplantation journals.

BACKGROUND: In their book Spare Parts, published in 1992, Fox and Swazey criticized various aspects of organ transplantation, including the routinization of the procedure, ignorance regarding its inherent uncertainties, and the ethos of transplant professionals. Using this work as a frame of reference, we analyzed articles on organ transplantation published in internal medicine and transplantation journals between 1995 and 2008 to see whether Fox and Swazey's critiques of organ transplantation were still relevant. METHODS: Using the PubMed database, we retrieved 1,120 articles from the top ten internal medicine journals and 4,644 articles from the two main transplantation journals (Transplantation and American Journal of Transplantation). Out of the internal medicine journal articles, we analyzed those in which organ transplantation was the main topic (349 articles). A total of 349 articles were randomly selected from the transplantation journals for content analysis. RESULTS: In our sample, organ transplantation was described in positive terms and was presented as a routine treatment. Few articles addressed ethical issues, patients' experiences and uncertainties related to organ transplantation. The internal medicine journals reported on more ethical issues than the transplantation journals. The most important ethical issues discussed were related to the justice principle: organ allocation, differential access to transplantation, and the organ shortage. CONCLUSION: Our study provides insight into representations of organ transplantation in the transplant and general medical communities, as reflected in medical journals. The various portrayals of organ transplantation in our sample of articles suggest that Fox and Swazey's critiques of the procedure are still relevant.

Automated screening of potential organ donors using a temporal machine learning model.

Organ donation is not meeting demand, and yet 30-60% of potential donors are potentially not identified. Current systems rely on manual identification and referral to an Organ Donation Organization (ODO). We hypothesized that developing an automated screening system based on machine learning could reduce the proportion of missed potentially eligible organ donors. Using routine clinical data and laboratory time-series, we retrospectively developed and tested a neural network model to automatically identify potential organ donors. We first trained a convolutive autoencoder that learned from the longitudinal changes of over 100 types of laboratory results. We then added a deep neural network classifier. This model was compared to a simpler logistic regression model. We observed an AUROC of 0.966 (CI 0.949-0.981) for the neural network and 0.940 (0.908-0.969) for the logistic regression model. At a prespecified cutoff, sensitivity and specificity were similar between both models at 84% and 93%. Accuracy of the neural network model was robust across donor subgroups and remained stable in a prospective simulation, while the logistic regression model performance declined when applied to rarer subgroups and in the prospective simulation. Our findings support using machine learning models to help with the identification of potential organ donors using routinely collected clinical and laboratory data.

Living Donor Kidney Transplantation in Quebec: A Qualitative Case Study of Health System Barriers and Facilitators.

Background: Patients with kidney failure represent a major public health burden, and living donor kidney transplantation (LDKT) is the best treatment option for these patients. Current work to optimize LDKT delivery to patients has focused on microlevel interventions and has not addressed interdependencies with meso and macro levels of practice. Objective: We aimed to learn from a health system with historically low LDKT performance to identify facilitators and barriers to LDKT. Our specific aims were to understand how LDKT delivery is organized through interacting macro, meso, and micro levels of practice and identify what attributes and processes of this health system facilitate the delivery of LDKT to patients with kidney failure and what creates barriers. Design: We conducted a qualitative case study, applying a complex adaptive systems approach to LDKT delivery, that recognizes health systems as being made up of dynamic, nested, and interconnected levels, with the patient at its core. Setting: The setting for this case study was the province of Quebec, Canada. Participants: Thirty-two key stakeholders from all levels of the health system. This included health care professionals, leaders in LDKT governance, living kidney donors, and kidney recipients. Methods: Semi-structured interviews with 32 key stakeholders and a document review were undertaken between February 2021 and December 2021. Inductive thematic analysis was used to generate themes. Results: Overall, we identified strong links between system attributes and processes and LDKT delivery, and more barriers than facilitators were discerned. Barriers that undermined access to LDKT included fragmented LDKT governance and expertise, disconnected care practices, limited resources, and regional inequities. Some were mitigated to an extent by the intervention of a program launched in 2018 to increase LDKT. Facilitators driven by the program included advocacy for LDKT from individual member(s) of the care team, dedicated resources, increased collaboration, and training opportunities that targeted LDKT delivery at multiple levels of practice. Limitations: Delineating the borders of a "case" is a challenge in case study research, and it is possible that some perspectives may have been missed. Participants may have produced socially desirable answers. Conclusions: Our study systematically investigated real-world practices as they operate throughout a health system. This novel approach has cross-disciplinary methodological relevance, and our findings have policy implications that can help inform multilevel interventions to improve LDKT.

Contexte: Les patients atteints d'insuffisance rénale représentent un lourd fardeau pour la santé publique, et la transplantation rénale provenant d'un donneur vivant (TRDV) est la meilleure option de traitement pour ces patients. Les travaux actuels visant à optimiser la TRDV chez les patients ont été limités à des interventions de niveau micro et n'ont pas abordé les interdépendances avec les niveaux méso et macro de la pratique. Objectifs: Notre objectif était d'apprendre d'un système de santé présentant un taux historiquement bas de TRDV pour arriver à déterminer les facteurs qui constituent un facilitateur ou un frein à la TRDV. Plus précisément, nous souhaitions, par le biais d'interactions entre les niveaux macro, méso et micro de la pratique, comprendre la façon dont la TRDV est organisée. Nous souhaitions également déterminer quels attributs et processus du système de santé constituent des facilitateurs ou des freins à la TRDV pour les patients atteints d'insuffisance rénale. Conception: Nous avons appliqué une approche de systèmes adaptatifs complexes à la TRDV pour mener une étude de cas qualitative qui reconnaît que les systèmes de santé sont constitués de niveaux dynamiques, imbriqués et interconnectés, où le patient est au cœur des interventions. Cadre: Cette étude de cas avait pour cadre la province de Québec (Canada). Participants: 32 intervenants clés de tous les niveaux du système de santé, notamment des professionnels de la santé, des leaders impliqués dans la gestion de la TRDV, des donneurs vivants d'un rein et des receveurs de rein. Méthodologie: Des entrevues semi-structurées avec 32 intervenants clés et un examen des documents ont été entrepris entre février 2021 et décembre 2021. L'analyse thématique inductive a servi à générer les thèmes. Résultats: De façon générale, nous avons constaté qu'il existait des liens solides entre la TRDV et les attributs et processus du système, et que les obstacles étaient plus nombreux que les facilitateurs. Les obstacles freinant l'accès à la TRDV comprenaient la gouvernance et l'expertise fragmentées en lien avec la TRDV, les pratiques de soins déconnectées, les ressources limitées et les inégalités régionales. Certains de ces obstacles ont été atténués dans une certaine mesure par l'intervention d'un programme lancé en 2018 pour accroître la TRDV. Les facilitateurs soutenus par le programme comprenaient la promotion de la TRDV par des membres individuels de l'équipe de soins, la disponibilité de ressources dédiées, une collaboration accrue et les possibilités de formation ciblant la TRDV à plusieurs niveaux de pratique. Limites: La délimitation des frontières de ce que constitue un « cas ¼ est un défi dans la recherche d'études de cas; il est ainsi possible que certaines perspectives aient été manquées. Les participants pourraient avoir donné des réponses socialement souhaitables. Conclusion: Notre étude a examiné systématiquement les pratiques en contexte réel, tel qu'elles fonctionnent dans l'ensemble d'un système de santé. Cette nouvelle approche présente une pertinence méthodologique interdisciplinaire et nos conclusions ont des implications politiques qui pourraient aider à orienter des interventions à plusieurs niveaux pour améliorer la TRDV.
