Background: Patients with end-stage kidney disease have multiple treatment options including renal transplantation which offers superior survival and quality of life compared to dialysis with less financial burden. A recent analysis has identified only 12.1% of patients in Australia being actively listed for renal transplantation within 12 months of commencing dialysis with significant variations between state jurisdictions. We present a pilot study assessing, at a single centre level, clinician identified factors associated with delayed active listing for kidney transplantation in Australia.
Methods: Data from National Organ Matching System and Australia and New Zealand Dialysis and Transplantation Registry were used to identify patients between the ages of 18-75 with an estimated 5-year post-transplant survival of greater than 90% receiving dialysis for more than 12 months. Individual surveys were forwarded to patient’s treating clinician requesting identification of reasons for prolonged time to wait-listing. 
Results: 92 patients were identified with 62 surveys completed. The average age was 45 years, 50% female patients, 83% of Caucasian ethnicity and an average of 4.09 years on dialysis. 54% of patients were current or previous cigarette smokers. 26 patients (31%) had been referred for transplant assessment and 37 patients (59%) had not been referred.
Of the patients who had been referred for transplantation assessment the primary barrier for listing was secondary medical factors in 13 patients (52%). Of these medical factors, obesity was the barrier in 6 patients (24%) and cardiovascular disease was a barrier for 4 (16%) patients. Social factors accounted for barriers for 10 patients (40%). 3 patients (12%) were undergoing workup for live donor transplantation and 5 patients (20%) were noted to have geographical barriers accessing listing for transplantation. 1 patient (4%) declined workup for transplantation.
For patients who had not been referred for deceased donor transplantation assessment the primary reason for not being referred was secondary medical factors which were identified as a reason in 24 patients (65%). Obesity was the leading cause for non-referral which was identified in 10 patients (27%) and uncontrolled infection was identified in 9 patients (24%). Social factors were also identified as a barrier to referral in 12 patients (49%).  8 patients (22%) did not want to proceed with renal transplantation.
Conclusions: A number of barriers face patients accessing timely wait listing for deceased donor renal transplantation. We demonstrate in a pilot single centre study secondary medical factors are the leading driver of delays for timely wait listing, or non-referral, for deceased donor transplantation. Further analysis is required to determine centre-based trends within Australia particularly assessing the burden of obesity in the end-stage renal failure population looking to proceed with deceased donor renal transplantation.
