Patient survival following renal transplantation in Indigenous populations: A systematic review

Kidney transplantation access and outcomes for Aboriginal and Torres Strait Islander children and young adults, 1963-2020: an ANZDATA registry study

OBJECTIVES

To 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 DESIGN

A cohort study based on prospectively collected data; analysis of Australia and New Zealand Dialysis and Transplant Registry (ANZDATA) data.

SETTING, PARTICIPANTS

Children and young adults aged 0-24 years who commenced kidney replacement therapy in Australia during 1963-2020.

MAIN OUTCOME MEASURES

Proportions 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.

RESULTS

During 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).

CONCLUSIONS

Five-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.

Challenges facing Indigenous transplant patients living in Canada: exploring equity and utility in organ transplantation decision-making

Indigenous peoples in Canada and in the Circumpolar North face a higher disease burden leading to end-stage organ failure and face geographic and systemic barriers to accessing health-care services, including those for end-stage organ failure and organ donation and transplantation (ODT). To address these issues, I present a think tank model used in Saskatchewan, Canada, which focused on ODT and recommended research and policy changes that address inequitable Indigenous access to ODT, most specifically in northern and remote regions. Over the past three years, think tank members, comprised of Indigenous cultural leaders, elders, and persons with lived experience in ODT, and complemented by medical and advocacy exports, have highlighted equity and utility issues as key concerns, and discussed ways in which these issues can be addressed. Recommendations include culturally-safe methods for documenting and tracking Indigenous identity, development of training to address culturally specific needs, and additional funding to support Indigenous transplant donors and recipients.
