Transition of young adult kidney transplant recipients

Inequalities in emergency care use across transition from paediatric to adult care: a retrospective cohort study of young people with chronic kidney disease in England

Transition of young people with chronic kidney disease (CKD) from paediatric to adult healthcare has been associated with poor outcomes, but few population-level studies examine trends in subgroups. We aimed to assess sociodemographic inequalities in changes in unplanned secondary care utilisation occurring across transfer to adult care for people with CKD in England. A cohort was constructed from routine healthcare administrative data in England of young people with childhood-diagnosed CKD who transitioned to adult care. The primary outcome was the number of emergency inpatient admissions and accident and emergency department (A&E) attendances per person year, compared before and after transfer. Injury-related and maternity admissions were excluded. Outcomes were compared via sociodemographic data using negative binomial regression with random effects. The cohort included 4505 individuals. Controlling for age, birth year, age at transfer, region and sociodemographic factors, transfer was associated with a significant decrease in emergency admissions (IRR 0.75, 95% CI 0.64-0.88) and no significant change in A&E attendances (IRR 1.10, 95% CI 0.95-1.27). Female sex was associated with static admissions and increased A&E attendances with transfer, with higher admissions and A&E attendances compared to males pre-transfer. Non-white ethnicities and higher deprivation were associated with higher unplanned secondary care use.

CONCLUSION

 Sociodemographic inequalities in emergency secondary care usage were evident in this cohort across the transition period, independent of age, with some variation between admissions and A&E use, and evidence of effect modification by transfer. Such inequalities likely have multifactorial origin, but importantly, could represent differential meetings of care needs.

WHAT IS KNOWN

• In chronic kidney disease (CKD), transfer from paediatric to adult healthcare is associated with declining health outcomes. • Known differences in CKD outcomes by sociodemographic factors have limited prior exploration in the context of transfer.

WHAT IS NEW

• Population-level data was used to examine the impacts of transfer and sociodemographic factors on unplanned secondary care utilisation in CKD. • Healthcare utilisation trends may not reflect known CKD pathophysiology and there may be unexplored sociodemographic inequalities in the experiences of young people across transfer.

The EKFC equation outperforms the CKD-EPI and CKiD equations for GFR estimation in adolescent and young adult kidney transplant patients

AIM

This study evaluated the bias and accuracy of the CKD-EPI/CKiD and EKFC equations compared with the reference exogenous tracer-based assessment of glomerular filtration rate (GFR) in adult and pediatric patients according to their renal transplant status.

METHODS

We assessed the bias and P30 accuracy of the CKD-EPI/CKiD and EKFC equations compared with iohexol-based GFR measurement.

RESULTS

In the overall population (n = 59), the median age was 29 years (IQR, 16.0-46.0) and the median measured GFR was 73.9 mL/min/1.73m2 (IQR, 57.3-84.6). Among non-kidney transplant patients, the median was 77.7 mL/min/1.73m2 (IQR, 59.3-86.5), while among kidney transplant patients, it was 60.5 mL/min/1.73m2 (IQR, 54.2-66.8). The bias associated with the EKFC and CKD-EPI/CKiD equations was significantly higher among kidney transplant patients than among non-kidney transplant patients, with a difference between medians (Hodges-Lehmann) of +10.4 mL/min/1.73m2 (95% CI, 2.2-18.9; p = .02) for the EKFC and +12.1 mL/min/1.73m2 (95% CI, 4.2-21.4; p = .006) for the CKD-EPI/CKiD equations. In multivariable analysis, kidney transplant status emerged as an independent factor associated with a bias of >3.4 mL/min/1.73m2 (odds ratio, 7.7; 95% CI, 1.4-43.3; p = .02) for the EKFC equation and a bias of >13.4 mL/min/1.73m2 (odds ratio, 15.0; 95% CI, 2.6-85.7; p = .002) for the CKD-EPI/CKiD equations.

CONCLUSION

In our study, which included adolescent and young adult kidney transplant patients, both the CKD-EPI/CKiD and EKFC equations tended to overestimate the measured glomerular filtration rate, with the EKFC equation exhibiting less bias. Renal transplant status significantly influenced the degree of estimation bias.

Socioeconomic Position and Health Among Children and Adolescents With CKD Across the Life-Course

Children and adolescents in families of lower socioeconomic position (SEP) experience an inequitable burden of reduced access to healthcare and poorer health. For children living with chronic kidney disease (CKD), disadvantaged SEP may exacerbate their considerable disease burden. Across the life-course, CKD may also compromise the SEP of families and young people, leading to accumulating health and socioeconomic disadvantage. This narrative review summarizes the current evidence on relationships of SEP with kidney care and health among children and adolescents with CKD from a life-course approach, including impacts of family SEP on kidney care and health, and bidirectional impacts of CKD on SEP. It highlights relevant conceptual models from social epidemiology, current evidence, clinical and policy implications, and provides directions for future research. Reflecting the balance of available evidence, we focus primarily on high-income countries (HICs), with an overview of key issues in low- and middle-income countries (LMICs). Overall, a growing body of evidence indicates sobering socioeconomic inequities in health and kidney care among children and adolescents with CKD, and adverse socioeconomic impacts of CKD. Dedicated efforts to tackle inequities are critical to ensuring that all young people with CKD have the opportunity to live long and flourishing lives. To prevent accumulating disadvantage, the global nephrology community must advocate for local government action on upstream social determinants of health; and adopt a life-course approach to kidney care that proactively identifies and addresses unmet social needs, targets intervening factors between SEP and health, and minimizes adverse socioeconomic outcomes across financial, educational and vocational domains.

Role of primary care in enhancing continuity of care for adolescents and young adults with chronic kidney disease undergoing transition to adult health services

The transition from pediatric to adult health care is a vulnerable period for adolescents and young adults (AYA) with chronic conditions as it involves a multitude of changes and challenges while they enter adulthood. The transition to adult care can be particularly challenging for AYA living with chronic kidney disease (CKD) due to the complex care needed for treatment. Continuity of care is crucial for a successful transition to adult health care. The aim of this educational review is to discuss the potential role of primary care providers in the transition from pediatric to adult health services for AYA with CKD and kidney failure treated with dialysis and/or transplant. We address the significance of the medical home model and how it can provide continuity of care for AYA with CKD. Primary care providers can enhance care for AYA with chronic conditions by providing continuity of care, reducing exacerbation of chronic health conditions, providing holistic care, and fostering collaboration with specialists. Despite their vital role, primary care providers face barriers in maintaining this continuity, necessitating further attention and support in this area. By addressing these barriers and encouraging primary care providers to work alongside pediatric and adult nephrologists during the transition to adult health care, there are significant opportunities to improve the care and health outcomes of AYA with CKD.

Time-Varying Determinants of Graft Failure in Pediatric Kidney Transplantation in Europe

BACKGROUND

Little is known about the time-varying determinants of kidney graft failure in children.

METHODS

We performed a retrospective study of primary pediatric kidney transplant recipients (younger than 18 years) from the Eurotransplant registry (1990-2020). Piece-wise exponential additive mixed models were applied to analyze time-varying recipient, donor, and transplant risk factors. Primary outcome was death-censored graft failure.

RESULTS

We report on 4528 kidney transplantations, of which 68% with deceased and 32% with living donor. One thousand six hundred and thirty-eight recipients experienced graft failure, and 168 died with a functioning graft. Between 2011 and 2020, the 5-year graft failure risk was 10% for deceased donor and 4% for living donor kidney transplant recipients. Risk of graft failure decreased five-fold from 1990 to 2020. The association between living donor transplantation and the lower risk of graft failure was strongest in the first month post-transplant (adjusted hazard ratio, 0.58; 95% confidence interval, 0.46 to 0.73) and remained statistically significant until 12 years post-transplant. Risk factors for graft failure in the first 2 years were deceased donor younger than 12 years or older than 46 years, potentially recurrent kidney disease, and panel-reactive antibody >0%. Other determinants of graft failure included dialysis before transplantation (until 5 years post-transplant), human leukocyte antigen mismatch 2-4 (0-15 years post-transplant), human leukocyte antigen mismatch 5-6 (2-12 years post-transplant), and hemodialysis (8-14 years post-transplant). Recipients older than 11 years at transplantation had a higher risk of graft failure 1-8 years post-transplant compared with other age groups, whereas young recipients had a lower risk throughout follow-up. Analysis of the combined effect of post-transplant time and recipient age showed a higher rate of graft failure during the first 5 years post-transplant in adolescents compared with young transplant recipients. In contrast to deceased donor younger than 12 years, deceased donor older than 46 years was consistently associated with a higher graft failure risk.

CONCLUSIONS

We report a long-term inverse association between living donor kidney transplantation and the risk of graft failure. The determinants of graft failure varied with time. There was a significant cumulative effect of adolescence and time post-transplant. The ideal donor age window was dependent on time post-transplant.

Resource use and costs of transitioning from pediatric to adult care for patients with chronic kidney disease

BACKGROUND

The structured transition of adolescents and young adults with chronic kidney disease (CKD) from pediatric to adult care is important, but data on the time and resources required for the necessary components of the transition process and the associated costs are lacking.

METHODS

In a prospective single-center cohort study of 52 patients with pre-transplant CKD (CKD stage 1, n = 10; stage 2, n = 6; stage 3, n = 5; stage 4 and 5, 1 patient each) or kidney transplant recipients (KTR), resource use and costs were evaluated for the key elements of a structured transition pathway, including (i) assessment of patients' disease-related knowledge and needs, (ii) required education and counseling sessions, and (iii) compiling an epicrisis and a transfer appointment of the patient with the current pediatric and the future adult nephrologist.

RESULTS

Forty-four of 52 enrolled patients (84.6%) completed the transition pathway and were transferred to adult care. The mean time from the decision to start the transition process until the final transfer consultation was 514 ± 204 days. The process was significantly longer for KTR (624 ± 150 [range, 307-819] days) than for patients with pre-transplant CKD (365 ± 172 [range, 1-693] days; P < 0.0001). The cumulative costs of all counseling and education sessions performed including the transfer appointment were 763 ± 473 Euro; it was significantly higher in KTR (966 ± 457 Euro) than in patients with pre-transplant CKD (470 ± 320 Euro; P < 0.0001).

CONCLUSIONS

A structured transition pathway for patients with CKD is resource and time-consuming due to the complexity of the disease and should be sufficiently funded. A higher-resolution version of the Graphical abstract is available as Supplementary information.

Transition of Care in Children with Chronic Kidney Disease, Dialysis, and Transplantation

Improvement in management of pediatric renal disorders has led to patient survival rates of 85-90%, increasing the number of adolescent and young adult (AYA) patients with childhood onset chronic kidney disease (CKD) transitioning to adult care settings. Pediatric CKD patients differ from adults with CKD in view of early onset of disease (sometimes with fetal onset), different disease spectrum, the potential effect of CKD on neurodevelopment, and substantial involvement of parents in medical decision making. In addition to the usual challenges of emerging adulthood (graduation from school to work, independent living, peak in impulsivity and risk-taking behaviors), young adults with pediatric CKD need to learn to manage a serious medical condition independently. In kidney transplant patients, regardless of the age at transplantation, graft failure rates are higher during adolescence and young adulthood than at any other age. All pediatric CKD patients must move from a pediatric to adult-focused settings and this transition is a longitudinal process requiring collaboration and interactions of AYA patients, their families, providers, health care environment and agencies. Consensus guidelines have provided recommendations to pediatric and adult renal teams to enable successful transition. Suboptimal transition is a risk factor for poor adherence to treatment and unfavorable health outcomes. The authors discuss the process of transition as it applies to pediatric CKD patients and review challenges faced by patients/families, pediatric and adult nephrology teams. They provide some suggestions and available tools to optimize the transition of pediatric CKD patients to adult-oriented care.

Interventions to support adolescents and young adults with the healthcare transition from paediatric to adult nephrology health services: A scoping review protocol

Background

Due to technological advancements and improved medical management of adolescents and young adults (AYAs) living with renal disease, there has been an exponential increase noted in the number of patients advancing from the paediatric to the adult nephrology healthcare setting. Subsequently, more AYAs are required to undergo the process of healthcare transition from paediatric to adult healthcare services. This process can be a challenging period for young people and families and is often associated with a decline in physical and psychosocial health outcomes of AYAs with renal disorders. To ensure a successful transition, AYAs must develop the ability to manage their renal condition, including the medical and psychosocial aspects of their condition, independently. Despite significant research into the transition from paediatric to adult healthcare for this unique patient cohort, the transition period remains a challenge at times. This scoping review aims to map, explore, and understand the interventions that are currently available to offer positive perceptions and experiences of transition for both AYAs living with renal disorders and their families.

Methods

A systematic literature search will be conducted of PubMed, PsycInfo, CINAHL, ASSIA, EMBASE and Web of Science databases from the year 2000 to present. Two independent reviewers will screen the peer-reviewed literature obtained and assess them against the inclusion criteria to determine their inclusion eligibility. Data will be extracted and synthesised using a template refined by the authors. The scoping review will be undertaken in accordance with PRISMA-ScR guidelines. Data will undergo a formal critical appraisal using recognised appraisal tools.

Conclusions

Through mapping this knowledge, the scoping review will aim to identify interventions that are currently available and identify gaps within the literature. This evidence may support the development of transitional care interventions in the future, promote patient satisfaction, and improve patient outcome measures and experiences.

Transition From Pediatric to Adult Nephrology Care: Program Report of a Single-Center Experience

Purpose of program

Adolescents and young adults with chronic disease face many personal and systemic barriers that may impede their successful transition from pediatric to adult care, putting them at risk for treatment nonadherence, loss to follow-up, and poor health outcomes. Such barriers include impaired socioemotional functioning, overreliance on adult caregivers, lack of disease-specific knowledge, and poor coordination between pediatric and adult health care services. In 2007, we established a specialized youth to adult nephrology transition clinic at a tertiary care center to address these barriers and provide adolescents and young adults with renal disease followed at the affiliated children's hospital with a seamless transition to adult care.

Sources of information

The attending clinic nephrologist collected data prospectively for this quality improvement report.

Methods

The features of this specialized clinic included (1) single point of entry and single triage adult nephrologist, (2) ongoing follow-up with a single adult nephrologist who communicated with the pediatric nephrologists, and (3) a single specialized clinic nurse who provided disease-specific education and helped to ensure ongoing patient engagement and follow-up. Importantly, the transition patients were booked into regular appointment slots in the adult nephrologist's general clinic, which facilitated regular follow-up without additional resources. The salary of the transition clinic nurse was covered by an unrestricted grant. Patient visits were in-person, except between 2020 and 2021 when visits were by telephone due to the pandemic.

Key findings

A total of 213 patients were referred and assessed in the transition clinic from February 2007 until October 2022. Most referrals were from pediatric nephrologists. Among the patients, 29% had a hereditary kidney disease; in 71%, the disease was acquired. The most common disease was glomerulonephritis and ~30% of the patients suffered from a "rare" disease. Of the 213 patients, 123 (58%) continue to be followed up (mean follow-up: 4.8 years), 27 (13%) were transferred to other physicians, in part to accommodate treatment closer to patients' homes, and 29 (14%) without ongoing care needs were discharged. Only 33 (15%) were lost to follow-up. There were several advantages to the clinic, including the maintenance of accurate records, a process to minimize loss to follow-up, and a "critical mass" of patients with rare diseases, which facilitated development of special expertise in rare disease pathogenesis, diagnosis, treatment, and management of complications. Patients with glomerulonephritis demonstrated a stable serum creatinine over 3 to 15 years, and morbidity (as reflected by emergency room visits and hospitalizations) was low.

Limitations

Due to the relatively small numbers of patients in the disease categories, it was not possible to determine conclusively whether attendance of patients in the transition clinic reduced the rate of progression of kidney disease or morbidity.

Implications

A dedicated referral, triage, and follow-up process post-transition with only modest financial resources and personnel can result in accurate tracking of clinic data, as well as consistent and reliable follow-up and expert patient care.

Children Are Not Small Adults: Similarities and Differences in Renal Transplantation Between Adults and Pediatrics

Kidney transplantation is the treatment of choice for all patients with end-stage kidney disease, including pediatric patients. Graft survival in pediatrics was lagging behind adults, but now is comparable with the adult cohort. Although many of the protocols have been adopted from adults, there are issues unique to pediatrics that one should be aware of to take care of this population. These issues include recipient size consideration, increased incidence of viral infections, problems related to growth, common occurrence of underlying urological issues, and psychosocial issues. This article addresses the similarities and differences in renal transplantation, from preparing a patient for transplant, the transplant process, to post-transplant complications.

Incidence and Causes of Early Hospital Readmissions After Living-Donor Renal Transplant at King Abdulaziz Medical City, Riyadh

BACKGROUND

 Living-donor organ transplant has a higher long-term survival rate compared to deceased-donor organ transplant, with kidney transplantation being the optimal treatment for most kidney failure patients. However, early hospital readmission within 30 days of discharge can occur due to various factors and can negatively affect long-term outcomes. Effective communication with patients pre-and post-transplant is crucial for a better quality of life and for reducing readmissions. Chronic kidney disease and co-morbid conditions must also be addressed for better long-term outcomes. The incidence and causes of early hospital readmission vary depending on local characteristics and other factors.

METHODS

 A retrospective cohort study of outcomes in patients who underwent living-donor renal transplantation at King Abdulaziz Medical City (KAMC) between 2015 and 2022. Data were collected by chart review using the BestCare system. The data collected included patients' demographics, comorbidities, surgery-related data, and the outcome of transplantation. The categorical data were presented using percentages and frequencies, while the numerical data were presented as mean and standard deviation. The Chi-square test was used for inferential statistics to find the association between categorical variables.

RESULTS

 Regarding sociodemographic characteristics, the majority of patients were male, aged 19-50 years, and either overweight or had obesity class 1. The incidence of complications, graft failure, and mortality after renal transplant was low, with only a small percentage of patients experiencing these outcomes within one year of transplant. There is no significant association between gender, age, BMI, and the likelihood of readmission after renal transplantation. Patients with comorbidities such as hypertension, diabetes, and coronary artery disease had a higher likelihood of readmission after renal transplantation. The study provides an association between readmission after renal transplantation and various factors such as surgical complications, previous transplant, age at transplant, graft failure, and mortality. Out of the 107 readmitted patients, 2.8% had surgical complications, and 5.6% had a previous transplant, but the association was not statistically significant.

CONCLUSION

 Early hospital readmission within 30 days of discharge can be a concern for patients undergoing renal transplants. While the incidence of complications, graft failure, and mortality after renal transplant was low, patients with comorbidities such as hypertension, diabetes, and coronary artery disease had a higher likelihood of readmission after renal transplantation. Although the association between surgical complications and readmission was not statistically significant, it is important to continue monitoring this factor in future studies. Effective communication with patients pre-and post-transplant can play a crucial role in reducing readmissions and improving long-term outcomes.
