Improving pre-emptive access to the kidney transplant waiting list between 2017 and 2021: Assessment of a regional program in Aquitaine

Introduction

Pre-emptive access to the kidney transplant (KT) waiting list remains limited in France, with only 3.9% of patients on pre-emptive KT and 5.6% of patients registered at the time of initiation of dialysis. A similar trend was observed in Aquitaine. The aim of this study was to assess the impact of a regional program in terms of access to the waiting list for patients initiating a kidney replacement therapy (KRT).

Methods

We included all patients assessed for registration on the list between 2017 and 2020, 2017 being the reference year and 2018 the beginning of the program. Using the CRISTAL and REIN registries, we assessed changes in the number of patients on the list at the time of initiation of dialysis or transplantation.

Results

The number of new assessed candidates increased gradually each year from 255 in 2017 to 352 in 2020 (+38%). The number of patients on the list sharply increased in 2018 from 229 in 2017 to 319 in 2018 (+39.3%) and then remained stable. At the initiation of KRT, the proportion of patients registered on the waiting list increased gradually from 7.1% in 2017 to 18.2% in 2020. The proportion of pre-emptive KT remained stable between 2017 and 2021 (around 7%) with a decrease in 2020 (4.6%). Approximately 60% of patients had a contraindication to transplantation throughout the study.

Conclusion

This study showed that a regional program aimed at providing better information to healthcare professionals and patients and encouraging rapid assessment of transplant candidates could increase the rate of pre-emptive registration on the KT waiting list for eligible patients over 4 years.

Health economics aspects of kidney transplantation in Sicily: a benchmark analysis on activity and estimated savings

Background

International and national registries consistently report substantial differences in kidney transplant (KT) activity despite demonstrable clinical and financial benefits. The study aims to estimate the financial resources gained by KT and produce a benchmark analysis that would inform adequate strategies for the growth of the service.

Methods

We analyzed the KT activity in our region between 2017 and 2019. The benchmark analysis was conducted with programs identified from national and international registries. The estimate of financial resources was obtained by applying the kidney transplant coefficient of value; subsequently, we compared the different activity levels and savings generated by the three KT programs.

Findings

The KT activity in the region progressively declined in the study years, producing a parallel reduction of the estimated savings. Such savings were substantially inferior when compared to those generated by benchmark programs (range €18-22 million less).

Interpretation

The factors influencing the reduced KT activity in the study period with the related "foregone savings" are multiple, as well as interdependent. Organ donation, access to the transplant waiting list, and KT from living donors appear to be the most prominent determinants of the observed different levels of activities. International experience suggests that a comprehensive strategy in the form of a "task force" may successfully address the critical areas of the service reversing the observed trend. The financial impact of a progressively reduced KT activity may be as critical as its clinical implications, jeopardizing the actual sustainability of services for patients with end-stage kidney disease.

Outcomes of Frail Patients While Waiting for Kidney Transplantation: Differences between Physical Frailty Phenotype and FRAIL Scale

Frailty is associated with poorer outcomes among patients waiting for kidney transplantation (KT). Several different tools to measure frailty have been used; however, their predictive value is unknown. This is a prospective longitudinal study of 449 KT candidates evaluated for frailty by the Physical Frailty Phenotype (PFP) and the FRAIL scale. During the study period, 296 patients received a KT, while 153 remained listed. Patients who did not get receive a transplant were more frequently frail according to PFP (16.3 vs. 7.4%, p = 0.013). Robust patients had fewer hospital admissions during the 1st year after listing (20.8% if PFP = 0 vs. 43.4% if ≥1, and 27.1% if FRAIL = 0 vs. 48.9% if ≥1) and fewer cardiovascular events (than FRAIL ≥ 1) or major infectious events (than PFP ≥ 1). According to PFP, scoring 1 point had an impact on patient survival and chance of transplantation in the univariate analysis. The multivariable analysis corroborated the result, as candidates with PFP ≥ 3 had less likelihood of transplantation (HR 0.45 [0.26–0.77]). The FRAIL scale did not associate with any of these outcomes. In KT candidates, pre-frailty and frailty according to both the PFP and the FRAIL scale were associated with poorer results while listed. The PFP detected that frail patients were less likely to receive a KT, while the FRAIL scale did not.

Racial disparities in pediatric access to kidney transplantation: does socioeconomic status play a role?

Racial disparities persist in access to renal transplantation in the United States, but the degree to which patient and neighborhood socioeconomic status (SES) impacts racial disparities in deceased donor renal transplantation access has not been examined in the pediatric and adolescent end-stage renal disease (ESRD) population. We examined the interplay of race and SES in a population-based cohort of all incident pediatric ESRD patients <21 years from the United States Renal Data System from 2000 to 2008, followed through September 2009. Of 8452 patients included, 30.8% were black, 27.6% white-Hispanic, 44.3% female and 28.0% lived in poor neighborhoods. A total of 63.4% of the study population was placed on the waiting list and 32.5% received a deceased donor transplant. Racial disparities persisted in transplant even after adjustment for SES, where minorities were less likely to receive a transplant compared to whites, and this disparity was more pronounced among patients 18-20 years. Disparities in access to the waiting list were mitigated in Hispanic patients with private health insurance. Our study suggests that racial disparities in transplant access worsen as pediatric patients transition into young adulthood, and that SES does not explain all of the racial differences in access to kidney transplantation.
