Aim: To examine reasons underlying non-retrieval and non-utilisation of donor pancreata for solid pancreas transplantation in Australia and New Zealand (ANZ) and identify potentially useable organs from this cohort.

Background: Deceased donor pancreas non-utilisation has increased in Australia, UK and the USA. Pancreas non-retrieval has increased in Australia and is high in New Zealand. We hypothesised that deceased donor pancreata in ANZ were not being optimally identified, retrieved or utilised.

Methods: Deceased donors from 2007 to 2016 from the Australian and New Zealand Organ Donor (ANZOD) registry were analysed for reasons underlying non-authorisation of pancreas donation, and for pancreas non-retrieval or non-utilisation. These groups were then screened using Transplantation Society of Australia and New Zealand (TSANZ) deceased-donor criteria to identify potentially suitable solid-organ pancreas donors. Their characteristics were then compared to actual donors.

Results: 2998 donors had authorisation requested for pancreas donation during the study period. Donor medical unsuitability (37%) was the commonest reason for non-retrieval followed by donor age (25%) and logistics (14%). Several potential solid-organ pancreas donors (n=222) comprising 18/71 non-authorised (25%), 197/1765 non-retrieved (11%), and 7/131 non-utilised pancreata (5%) were identified. When compared to actual donors, only donor region of origin, history of hypertension and cause of death were significantly different. Increasing donor upper-age limit to 50 years old resulted in an additional 62/1967 (3%) potential solid-organ pancreas donors.

Conclusions: Potential additional solid-organ pancreas donors exist within the non-authorised, non-retrieved and non-utilised pancreas donor groups in ANZ. Further research into increasing solid-organ pancreas donor upper-age limits, and minimising logistical barriers to pancreas retrieval are necessary to minimise non-retrieval and non-utilisation of potentially transplantable donor pancreata.
