Evaluation of the use of a Renal Health application by kidney transplant recipients / Avaliação do uso do aplicativo Renal Health por transplantados renais / Evaluación del uso de la Aplicación Renal Health por parte de los receptores de trasplante renal

Abstract Objective: to evaluate the use of a renal health application by kidney transplant recipients. Method: a retrospective, observational study with a sample composed of individuals registered in the kidney transplant section of the application from July of 2018 to April of 2021. Demographic data, data entry, time of use, weight, blood pressure, blood glucose, creatinine, medication schedules, appointments, and tests were the variables collected. Descriptive analysis of the data was performed. Results: eight hundred and twenty-three downloads of the application were identified, and 12.3% of those were registered as kidney transplant recipients, the majority from southeastern Brazil (44.9%), 36±11 years old, and female (59.1%). Of the sample, 35.1% entered information such as creatinine (62%), weight (58.2%), and blood pressure (51.8%). Most used the application for one day (63.3%) and 13.9% for more than one hundred days. Those who used it for more than one day (36.7%) recorded weight (69%), medication intake (65.5%) and creatinine (62%), and scheduled appointments (69%). Conclusion: the kidney transplant recipient section of the Renal Health application generated interest in the young population, but showed low adherence throughout the assessed months. These results offer a relevant perspective on the implementation of mHealth technologies in kidney transplantation.

Interpersonal Connections Are Important for Virtual Kidney Transplant Educational Program Development.

Introduction: The Living Donor Navigator program is designed to mitigate disparities in living donor kidney transplantation, although geographic disparities in program participation were observed in the initial years of implementation. The purpose of this study was to understand participant perspectives regarding the use of a virtual option/alternative to expand program participation. Methods: Previous participants of the in-person navigator program were purposively sampled. Using the nominal group technique, a well-structured formative methodology to elicit participant perspectives, 2 meetings were conducted among transplant recipients and advocates (N = 13) to identify and prioritize responses to the question "What things would concern you about participating in a virtual and remote Living Donor Navigator program?" Findings: Mean participant age was 59.3 (9.3) years, and participants were 54% male and 62% white. Education levels varied from less than high school to master's degrees. Participants generated 70 unique responses, of which 36 (51.4%) received prioritization. The top 5 ranked responses of each nominal group technique meeting received approximately 50 percent (47.6% vs. 66.7%, respectively) of the total votes and described the potentially limited interpersonal connections, time conflicts, and differing content in a virtual navigator program compared to the in-person model. Discussion: These data suggest that previous participants were concerned with upholding the original design of the program, thus, virtual living donor kidney transplantation programs should aim to maintain interpersonal connections and consistency of content to ensure adequate programmatic engagement. Future research will focus on program fidelity independent of delivery modality.

Trasplante renal en la próxima década: estrategias, retos y visión de futuro / Kidney transplant in the next decade: Strategies, challenges and vision of the future

Aunque los resultados del trasplante renal (TR) han mejorado sustancialmente en los últimos años, continúa observándose una pérdida crónica e inexorable de los injertos debido principalmente a la muerte del paciente y a la disfunción crónica del TR. Por tanto, los objetivos para optimizar esta situación en la próxima década se centran fundamentalmente en minimizar la tasa de pérdida de injertos renales, mejorar la supervivencia de los pacientes, incrementar la tasa de obtención de órganos y su distribución, fomentar la investigación y la formación de los profesionales sanitarios y la elaboración de registros científicos que proporcionen una información clínica y fiable que nos permita optimizar nuestra práctica clínica en el campo del TR. Con esta perspectiva, esta revisión profundizará en: 1) estrategias para evitar la disfunción crónica y la pérdida del injerto a medio y largo plazo; 2) prolongar la supervivencia del paciente; 3) estrategias para incrementar la donación, mantenimiento y distribución de órganos; 4) promocionar la investigación clínica y básica y la actividad formativa en TR; y 5) el análisis de los resultados en TR mediante la optimización y fusión de los registros.

Although the results of kidney transplantation (KT) have improved substantially in recent years, a chronic and inexorable loss of grafts mainly due to the death of the patient and chronic dysfunction of the KT, continues to be observed. The objectives, thus, to optimize this situation in the next decade are fundamentally focused on minimizing the rate of kidney graft loss, improving patient survival, increasing the rate of organ procurement and its distribution, promoting research and training in health professionals and the development of scientific registries providing clinical and reliable information that allow us to optimize our clinical practice in the field of KT. With this perspective, this review will deep into: (1) strategies to avoid chronic dysfunction and graft loss in the medium and long term; (2) to prolong patient survival; (3) strategies to increase the donation, maintenance and allocation of organs; (4) promote clinical and basic research and training activity in KT; and (5) the analysis of the results in KT by optimizing and merging scientific registries.

The 3-Step Model of informed consent for living kidney donation: a proposal on behalf of the DESCaRTES Working Group of the European Renal Association.

Living donation challenges the ethical principle of non-maleficence in that it exposes healthy persons to risks for the benefit of someone else. This makes safety, informed consent (IC) and education a priority. Living kidney donation has multiple benefits for the potential donor, but there are also several known short- and long-term risks. Although complete standardization of IC is likely to be unattainable, studies have emphasized the need for a standardized IC process to enable equitable educational and decision-making prospects for the prevention of inequities across transplant centers. Based on the Three-Talk Model of shared decision-making by Elwyn et al., we propose a model, named 3-Step (S) Model, where each step coincides with the three ideal timings of the process leading the living donor to the decision to pursue living donation: prior to the need for kidney replacement therapy (team talk); at the local nephrology unit or transplant center, with transplant clinicians and surgeons prior to evaluations start (option talk); and throughout evaluation, after having learned about the different aspects of donation, especially if there are second thoughts or doubts (decision talk). Based on the 3-S Model, to deliver conceptual and practical guidance to nephrologists and transplant clinicians, we provide recommendations for standardization of the timing, content, modalities for communicating risks and assessment of understanding prior to donation. The 3-S Model successfully allows an integration between standardization and individualization of IC, enabling a person-centered approach to potential donors. Studies will assess the effectiveness of the 3-S Model in kidney transplant clinical practice.

A Home Education Service to Increase Knowledge of Treatment Options and Improve Attitudes to Living Donor Kidney Transplantation.

Introduction: Lack of knowledge about living donor kidney transplant and difficulties in approaching potential donors constitute barriers for many patients and may contribute to inequality of access. Project Aims: Renal Education and Choices at Home was a UK single-centre pilot of home education; an initiative aiming to overcome barriers by increasing knowledge among patients and support networks and by facilitating living donation discussion in the patient's home. Design: This was a pre-post comparison of knowledge, attitude, and ability to communicate about transplant. Pre-visit knowledge about treatment options and attitudes towards transplant were measured using a validated questionnaire, repeated 4-6 weeks post-visit, to assess the session's impact, along with an evaluation survey, to determine how patients perceived the session. Results: From November 2018 to February 2020, a nurse specialist delivered living donor transplant education sessions in the homes of 86 patients, attended by 141 additional invitees. Home visits led to a significant improvement in knowledge about renal therapies, including living donor transplantation. The evaluation of the home visits by patients and invitees was overwhelmingly positive. Of the 86 patients visited, 46 (53%) had at least one potential donor initiating the assessment process following the visit. Overall, 78 potential donors initiated the assessment process. Conclusion: Home education contributed to addressing recognised barriers, in a way that was well received by patients and was novel in our health system. Home education may be particularly beneficial for patients affected by known barriers to living donor transplantation such as socio-economic deprivation.

Receipt and Sharing of Information to Improve Knowledge About Living Donor Kidney Transplant among Transplant Candidates with Advanced Chronic Kidney Disease.

Introduction: Knowledge about living donor kidney transplant (LDKT) is associated with greater access. Yet, little is known about factors associated with high living donor transplant knowledge. Research Questions: Is receipt of LDKT information from health professionals or sharing information with family and friends associated with higher knowledge? Design: We conducted a cross-sectional analysis of data from preemptive LDKT candidates, which assessed knowledge, receipt of information about living donation from health professionals, and history of having shared living donor information with family members or friends. In multivariable logistic regression models adjusting for participants' age, race, and total household income, we quantified the association of high knowledge with receipt of living donation information from health professionals and sharing of this information with family/friends. Results: Among 130 participants, the median (IQR) age was 59.5 (52.0-65.0) years, 60% were female, 47.7% were Black, and 49.2% had a high school education or less. Over half (55.4%) had high LDKT knowledge. Nearly one third reported having received living donor information (33.1%) or sharing the information with family/friends (28.5%). After adjustment, those who received (vs. did not receive information) and shared information with family/friends had 3-fold higher odds of high LDKT knowledge (3.05 [1.24, 8.08]). Individuals who received LDKT information (vs. did not) from health professionals had 4-fold higher odds of high LDKT knowledge (adjusted OR [95% CI]: 4.01 [1.49, 12.18]. Conclusions: Receipt of living donation information from health professionals and sharing this information with family/friends were associated with high LDKT knowledge.

A Mixed Methods Assessment of Home-Based Video Pretransplant Lung Education.

Introduction: Patients awaiting lung transplantation must learn new information to successfully navigate the transplant process. A supplemental video series was piloted to patients at home during the Covid-19 pandemic to improve pre-transplant education. Methods: A mixed methods study was undertaken to assess patient experiences with this method of education, confirm the ideal timing of the education, and identify gaps that require further attention. Semi-structured interviews were conducted with 17 one-on-one or dyadic (patients and caregivers) who viewed the video series at home. A third-party researcher (not involved in creation of the educational materials) conducted the interviews by phone, which were audio recorded and then transcribed verbatim. NVivo 12 Pro for Windows software was used to code the data and identify emerging themes. Results: Participants indicated that home-based videos were applicable, and informative and helpful (4.7 on 5-point Likert scale) and appreciated the advice and experiences of real patients. They were satisfied with their transplant education (4.2/5). While there were few aspects that the participants disliked about the videos, the interviews elicited outstanding questions about the transplant process (eg, logistical aspects of travel) and transplant concerns (eg, medications, expenses, and precautions in daily life). Conclusion: Patients being assessed or listed for lung transplant valued the novel electronic video education, and we will implement the home-based process into standard of care after the patient's initial visit with the transplant respirologist. Pre-transplant education will be tailored to help address the outstanding gaps identified in this program evaluation.

Using Focus Groups to Understand Dialysis Staff Perspectives on Delivering Transplant Education.

INTRODUCTION: Kidney transplant education in dialysis facilities could be optimized with internet resources, like videos, but most qualitative research predates widespread availability of online video education about kidney transplantation. To improve understanding of dialysis staff transplant education practices, as well as the potential value of video, we conducted focus groups of dialysis center staff members in Buffalo, NY. METHODS/APPROACH: Seventeen focus groups (97 participants: 53 nurses, 10 dialysis technicians, 6 social workers, 6 dieticians, 7 administrative personnel, 2 trainees, and 1 insurance coordinator) from 8 dialysis facilities in Buffalo, NY, were conducted, audio-recorded, transcribed, and analyzed. After thematic data analysis, a diverse patient and caregiver community advisory board was invited to comment, and their voices were integrated. Findings: Five key themes were identified that captured barriers to transplant education delivery and how online video could be a facilitator: (1) delivery of transplant education was reliant on one person, (2) other dialysis staff had time to answer transplant questions but felt uninformed, (3) patient lack of interest in existing supplementary transplant education, (4) patient disinterest in transplantation education was due to education timing, feeling overwhelmed, and transplant fear/ambivalence, and (5) video education could be flexible, low effort, and spark transplant interest. Study limitations are potential selection bias and inclusion of English-speaking participants only. DISCUSSION: Dialysis staff barriers of time, insufficient knowledge, and limited resources to provide education to patients and their care partners may be mitigated with online educational videos without increasing staff workload.

Count Me Out: Perceptions of Black Patients Who are on Dialysis but Who are Not on a Transplant Waitlist.

End-stage renal disease (ESRD) is characterized by racial inequity; Blacks are 3 times more likely to develop ESRD than Whites. Transplant is the preferred treatment option since transplanted patients experience better clinical outcomes. Racial inequities persist at each of the steps required for transplantation. Despite the vast literature describing these racial inequities, it does not include dialysis patients' awareness and understanding of treatment options, specifically for transplant. To address this gap, we purposely sampled Blacks in Detroit who were receiving dialysis and who were not active on any transplant waitlist to investigate their understanding and perceptions of transplants. We used uncertainty management theory (UMT) to better understand perceived barriers to getting and remaining on a transplant waitlist. We aimed to address a critical gap in the literature to inform approaches addressing this enduring inequity. For this qualitative study, we conducted individual, semi-structured interviews with 24 Black ESRD patients, aged 34-73 years: 9 male and 15 female. Participants shared their experiences of being on dialysis, perceptions, and understanding of transplants. We describe two key findings: 1) uncertainty for these patients is prevalent and multi-layered and 2) social support can both dissuade an individual from pursuing transplant (i.e., reluctance to ask family members to be donors) and it can result in decreasing uncertainty (e.g., participants wanting to pursue transplant to be with family). We highlight the specific need to improve patient education regarding treatment options and enhancing how relevant health information can be communicated.

Renal recipients' knowledge and self-efficacy during first year after implementing an evidence based educational intervention as routine care at the transplantation clinic.

BACKGROUND: Following an implementation plan based on dynamic dialogue between researchers and clinicians, this study implemented an evidence-based patient education program (tested in an RCT) into routine care at a clinical transplant center. The aim of this study was to investigate renal recipients' knowledge and self-efficacy during first year the after the intervention was provided in an everyday life setting. METHODS: The study has a longitudinal design. The sample consisted of 196 renal recipients. Measurement points were 5 days (baseline), 2 months (T1), 6 months (T2), and one-year post transplantation (T3). Outcome measures were post-transplant knowledge, self-efficacy, and self-perceived general health. RESULTS: No statistically significant changes were found from baseline to T1, T2, and T3. Participants' levels of knowledge and self-efficacy were high prior to the education program and did not change throughout the first year post transplantation. CONCLUSION: Renal recipients self-efficacy and insight in post-transplant aspects seem to be more robust when admitted to the hospital for transplantation compared to baseline observations in the RCT study. This may explain why the implemented educational intervention did not lead to the same positive increase in outcome measures as in the RCT. This study supports that replicating clinical interventions in real-life settings may provide different results compared to results from RCT's. In order to gain a complete picture of the impacts of an implemented intervention, it is vital also to evaluate results after implementing findings from RCT-studies into everyday practice.

Interactive Virtual Reality Renal Models as an Educational and Preoperative Planning Tool for Laparoscopic Donor Nephrectomy.

OBJECTIVE: To evaluate the efficacy of interactive virtual reality (iVR) in providing a three-dimensional (3D) experience with the donor's anatomy for surgeons and patients, we present a retrospective, case-controlled study assessing the impact of iVR renal models prior to LDN on both surgical outcomes and patients' understanding of the procedure. MATERIALS AND METHODS: Twenty patients undergoing LDN were prospectively recruited; their contrast-enhanced CT scans were transformed into iVR models. An iVR platform allowed the surgeons to rotate and deconstruct the renal anatomy; patients could also view their anatomy as the procedure was explained to them. Questionnaires assessed surgeons' understanding of renal anatomy after CT alone and after CT+iVR. Surgeons also commented on whether iVR impacted their preoperative plan. Patients assessed their anatomical understanding and anxiety level before and after iVR. Surgical outcomes for the iVR cohort were compared to a retrospectively matched, non-iVR cohort of LDN patients. RESULTS: Surgeons altered their preoperative plan in 18 of 20 LDNs after viewing iVR models. Patients reported better understanding of their anatomy (5/5) and noted decreased preoperative anxiety (5/5) after viewing iVR. When compared to the non-iVR group, the iVR group had a 25% reduction in median operative time (P < .001). In terms of surgical outcomes, patients in the iVR group had a 40% lower median relative change in postoperative creatinine (P < .001). CONCLUSION: Preoperative viewing of iVR models altered the operative approach, decreased the operative time, and improved donor patient outcomes. iVR models also reduced patients' preoperative anxiety.

Value-Based Care in Nephrology: The Kidney Care Choices Model and Other Reforms.

The Advancing American Kidney Health (AAKH) initiative has reinvigorated the focus on improving the care of patients with advanced CKD. Multiple interventions have been planned, focusing on education campaigns for both clinicians and patients, delaying the progression of kidney disease and improving utilization of home dialysis modalities and kidney transplantation. Value-based care models for patients with advanced kidney disease are being rolled out, with the ESKD treatment choices model starting in January 2021, and the Kidney Care Choices model planned to start in January 2022. There is increasing emphasis on the role of the nephrologist as the "captain of the ship," leading efforts in care coordination as physician leaders. The transplant reforms have focused on changes to organ procurement organizations aiming to increase availability of organs, and transplants performed, both deceased and living donor, and removing financial disincentives from live organ donation. The American Society of Nephrology (ASN) and the National Kidney Foundation (NKF) are partnering with the Department of Health and Human Services to develop educational material for clinicians and patients. In this review, we discuss these reforms, potential challenges that have arisen, and potential solutions, with emphasis on the Kidney Care Choices model.

The Transplant Nephrology Workforce in the United States: Current State and Future Directions.

The population of patients with kidney transplants in the United States is growing. The delivery of transplant care is complex, involves a multidisciplinary transplant team, and care coordination between transplant and community providers. The transplant nephrologist is central to the delivery of this care and assumes a multitude of clinical and nonclinical roles and responsibilities. With a growing population of patients requiring transplant care that spans a continuum from pretransplant referral to long-term posttransplant management, an understanding of the current state of the transplant nephrology workforce in the United States and the future that it faces is important in ensuring that current and future needs of both patients and physicians are met. In this article, we (1) review the scope of practice of the transplant nephrologist, (2) discuss the state of training in the field of transplant nephrology, (3) review the role of the referring primary nephrologist in the care of patients undergoing kidney transplant, and (4) discuss challenges and opportunities facing the transplant nephrology workforce.

Development of video-based educational materials for kidney-transplant patients.

INTRODUCTION: Treatment adherence has been evaluated as a major predictor of long-term outcome, and education has been suggested to improve adherence. Considering the characteristics of adult learners, it is necessary to implement educational programs that meet the needs of transplant patients. Multimedia education may be well-suited for this. This study aims to develop video education materials in accordance with transplant patients' self-care needs. METHODS: This study includes a literature review and patient interviews aimed at developing video education materials for the self-care needs of patients who underwent renal transplant surgery at a university hospital in Seoul. Ten patients were interviewed about the desired educational content, accessibility, and other preferences. After verifying the validity of the data, the video scenarios were produced and satisfaction surveys were conducted. RESULTS: Eleven self-care education items were identified through interviews with 10 kidney transplant patients. The expert validation of video-based educational content result was high (mean CVI = 0.94). The mean score of the patients' satisfaction evaluation of the completed 7-minute video instructional materials was also high (4.55 on a 5-point Likert scale). CONCLUSION: Findings indicate that the video education materials will meet the needs of adult learners and mitigate the limitations of the existing education programs by increasing interest and motivation and may contribute to increased treatment adherence and ultimately, positively effect self-care for new transplant patients.

Learning curve of kidney transplantation in a high-volume center: A Cohort study of 1466 consecutive recipients.

BACKGROUND: The purpose of this study was to evaluate surgical outcomes of kidney transplantation (KTX) based on surgeon volume and surgeon experience, and to develop the learning curve model for KTX using the cumulative sum (CUSUM) analysis. METHODS: A retrospective review of 1466 consecutive recipients who underwent KTX between 2010 and 2017 was conducted. In total, 51 surgeons, including certified transplant surgeons, transplant fellows and surgical residents were involved in these procedures using a standardized protocol. Outcomes were compared based on surgeon volume (low [1-30] versus high [31≥] volume) and surgeon's type (consultant surgeons, fellows or residents). RESULTS: Operative time (129 versus 135 min, P < 0.001) and warm ischemia time (20.9 versus 24.2 min, P < 0.001) were significantly shorter in the high-volume group, however postoperative outcomes were equal in both groups. The CUSUM analysis revealed that approximately 30 procedures were necessary to improve surgical skills. In addition, no effect of surgeon's type including consultant surgeons, fellows and residents on postoperative outcomes was found. CONCLUSIONS: Surgical training in KTX using a standardize protocol can be accomplished with a steep learning curve without compromising perioperative outcomes under the careful selection of surgeons and procedures.

Recommendations for Systematizing Transplant Education Within a Care Delivery System for Patients With Chronic Kidney Disease Stages 3 to 5.

CONTEXT: Early tailored transplant education could help patients make informed transplant choices. OBJECTIVE: We interviewed 40 patients with chronic kidney disease (CKD) stages 3 to 5, 13 support persons, and 10 providers at Kaiser Permanente Southern California to understand: (1) barriers to transplant education and (2) transplant educational preferences and recommendations based on CKD stage and primary language spoken. DESIGN: A grounded theory analysis identified central themes related to transplant education barriers, preferences, and recommendations. RESULTS: Barriers included confusion about diagnosis and when transplant may be necessary, concerns about transplant risks, families' lack of transplant knowledge, financial burdens, transportation and scheduling, and the emotional overload of chronic illness. Hispanic and Spanish-speaking participants reported difficulty in understanding transplant education and medical mistrust. Recommendations included providing general education, earlier introduction to transplant, wait-listing information, transplant education for support persons, living donation education for patients and potential donors, opportunities to meet living donors and kidney recipients, information on the benefits of transplant, recovery, and available financial resources, flexible class scheduling, online and print resources, and more provider follow-up. Spanish-speaking and Hispanic participants recommended using bilingual educators, print, video, and online resources in Spanish, and culturally responsive education. Patients with CKD stages 3 to 4 wanted information on slowing disease progression and avoiding transplant. CONCLUSION: Increasing access to culturally responsive transplant education in multiple languages, pairing appropriate content to the disease stage, and increasing system-wide follow-up as the disease progresses might help patients make more informed choices about transplant.

Cadaveric Models for Renal Transplant Surgery Education: a Comprehensive Review.

PURPOSE OF REVIEW: To evaluate the utility of cadaveric models for kidney transplant (KT) surgery training. RECENT FINDINGS: Medline® and PubMed® databases were searched for English and Spanish language articles published describing different learning models used in KT formation. We evaluated the use of cadavers preserved by Thiel's embalming method (TEM) as KT simulation models. Students were divided in groups of 4 people: four trainees mentored by an expert in KT surgery. Among the trainees were surgical residents and low-experience surgeons. A total of 39 TEM preserved bodies were used, of which 75 viable renal grafts were obtained. In each cadaver, two complete transplantation processes were performed, each consisting of en bloc nephrectomy with the trunk of aorta and inferior vena cava, bench surgery and perfusion with saline of the organ, and KT surgery. As with any surgical procedure, learning KT surgery is a stepwise process that requires years of dedication. The models available for the surgical simulation of KT surgery allow to practice and achieve dexterity in performing the procedure in a safe and reproducible way. Training on TEM-preserved corpses offers a highly realistic model for the surgical simulation of KT surgery.

Experimental Rat Model for Brain Death Induction and Kidney Transplantation.

Background: Experimental animal research has been pivotal in developing clinical kidney transplantation (KTx). One donor-associated risk factor with negative affect of transplantation outcome is brain death (BD). Many rat models for BD and KTx have been developed in the last decade, but no surgical guidelines have been developed for these models. Here, we describe a surgical technique for BD induction and the cuff technique for experimental KTx in rats.Methods: After intubation and mechanically ventilation of sixteen healthy adult male Sprague-Dawley rats were induction of BD performed. Animals were kept hemodynamically stable for eight hours. Then, the kidney was prepared and perfused with standard histidine-tryptophan-ketoglutarate solution. After explantation, grafts were immediately implanted in recipients using the cuff technique and reperfused. After 2 h of observation, animals were sacrificed by intravenous administration of potassium chloride.Results: In the early phase of BD, heart rate increased and mean arterial pressure decreased. Partial variations were observed in O2 partial pressure, O2 saturation, and HCO3. During the 2-h observation phase, all transplanted kidneys were sufficiently perfused macroscopically. There was no hyperacute rejection.Conclusions: It is feasible to observe BD for 8 h with maintained circulation in small experimental settings. The cuff technique for KTx is simple, the complication rate is low, and the warm ischemia time is short, therefore, this could be a suitable technique for KTx in the rat model.

Stakeholder perspectives of the clinical utility of pharmacogenomic testing in solid organ transplantation.

Aims: To assess stakeholder perspectives regarding the clinical utility of pharmacogenomic (PGx) testing following kidney, liver, and heart transplantation. Methods: We conducted individual semi-structured interviews and focus groups with kidney, liver, and heart transplantation patients and providers. We analyzed the qualitative data to identify salient themes. Results: The study enrolled 36 patients and 24 providers. Patients lacked an understanding about PGx, but expressed interest in PGx testing. Providers expressed willingness to use PGx testing, but reported barriers to implementation, such as lack of knowledge, lack of evidence demonstrating clinical utility, and patient healthcare burden. Conclusion: Patient and provider educational efforts, including foundational knowledge, clinical evidence, and applications to patient care beyond just immunosuppression, may be useful to facilitate the use of PGx testing in transplant medicine.
