ObjectivesTo assess differences between Aboriginal and Torres Strait Islander and non-Indigenous Australian children and young adults in access to and outcomes of kidney transplantation.Study DesignA cohort study based on prospectively collected data; analysis of Australia and New Zealand Dialysis and Transplant Registry (ANZDATA) data.Setting, ParticipantsChildren and young adults aged 0-24 years who commenced kidney replacement therapy in Australia during 1963-2020.Main Outcome MeasuresProportions of children and young adults who received kidney transplants within five years of commencing dialysis; 5- and 10-year death-censored graft survival; and 5- and 10-year survival of children and young adults who received kidney transplants or who remained on dialysis.ResultsDuring 1963-2020, 3736 children and young adults received kidney replacement therapy in Australia: 213 (5.8%) Aboriginal and Torres Strait Islander and 3523 (94.2%) non-Indigenous children and young adults. During follow-up (median, eight years; interquartile range [IQR], 2.6-15 years), 2762 children and young adults received kidney transplants: 93 Aboriginal and Torres Strait Islander (43.7% of those receiving kidney replacement therapy) and 2669 non-Indigenous children and young adults (75.8%). Smaller proportions of Aboriginal and Torres Strait Islander than of non-Indigenous children and young adults received transplants within five years of commencing dialysis (99, 46% v 2924, 83.0%), received living donor transplants (19, 20% v 1170, 43.9%), or underwent pre-emptive transplantation (one, 1.1% v 363, 13.6%). Five-year graft survival for Aboriginal and Torres Strait Islander recipients was similar to non-Indigenous recipients (61% v 75%; adjusted hazard ratio [aHR], 1.43; 95% confidence interval [CI], 0.02-2.05), but 10-year graft survival was lower (35% v 61%; aHR, 1.69; 95% CI, 1.25-2.28). Five- and 10-year survival after kidney transplantation was similar for Aboriginal and Torres Strait Islander and non-Indigenous people. Among those who remained on dialysis, 10-year survival was poorer for Aboriginal and Torres Strait Islander than non-Indigenous children and young adults (aHR, 1.50; 95% CI, 1.08-2.10).ConclusionsFive-year graft and recipient survival were excellent for Aboriginal and Torres Strait Islander children and young adults who received kidney transplants; however, a lower proportion received transplants within five years of dialysis initiation, than non-Indigenous children and young adults. Improving transplant access within five years of dialysis commencement should be a priority.© 2024 The Author(s).
