Examining barriers to timely waitlisting for kidney transplantation for Indigenous Australians in Central Australia

Background Indigenous Australians are disproportionately affected by end stage kidney disease. Despite this, they face significant delays being assessed and waitlisted for kidney transplant. Aims This study aimed to examine the kidney transplant waitlisting process in our region, to compare the workup process between Indigenous and non-indigenous patients, and identify major sources of delay. Methods We analysed the records of all patients being treated by our service who were on the kidney transplant waitlist between January 2017 and June 2018. Between-group differences were used to compare the time between commencement of dialysis and completion of each component of assessment. Patients who had more than 1 year between commencement of dialysis and waitlisting were further analysed for major sources of delay. Results Twenty-five patients were included (20 Indigenous and 5 non-indigenous). The median time to waitlisting for transplant after commencing dialysis was significantly longer in the Indigenous group (1215 vs 264 days, P = 0.032). Indigenous patients waited longer before commencing the transplant assessment process and before completing dental assessment, tissue typing and review by the transplant nephrologist and surgeon. Five patients (two Indigenous, three non-indigenous) were waitlisted within 1 year of commencing dialysis. Among the remaining 20 patients, cardiac and systems issues were the two most common major sources of delay. Conclusion Indigenous patients face significant delays accessing the kidney transplant waitlist. Cardiac assessment and systems issues are prominent sources of delay and efforts to address these areas may help to improve equity of access to kidney transplantation.
