Demographics of deceased donor renal transplants in Ireland: A 10 year review showing the worrying increase of suicide as a source for organ donation

Introduction

Kidney transplantation is the treatment of choice for patients with end stage renal disease. The primary aim of this study was to assess the demographics of deceased kidney donors over the last ten years and to assess for gender variations in deceased donor demographics over an extended period.

Methods

A retrospective data analysis was carried out using data from the national renal transplant database. All deceased donors who donated a kidney between 1st January 2012 and 31st December 2021 were included. Data points extracted included gender, age, cause of death and month of death. Descriptive analyses were carried out using Excel v16.67.

Results

A total of 1219 kidneys from 650 donors were donated over the ten-year period. The mean donor age was 44.01 years (range 1–74 years). The most common cause of death overall was subarachnoid haemorrhage (SAH), which was the cause of death in 27.8 % of donors (n = 180). Male donors accounted for 57.8 % of donors overall (n = 376). Variation in causes of death was observed between male and female donors, and between younger and older donors. 9 % of male deaths were from suicide compared with 5 % of female deaths. 6 % of male deaths were due to a traumatic head injury, with this accounting for 2 % of female deaths. Deaths due to assault made up 2 % of male donor deaths, but were not a cause of death for any female donors.

Conclusion

SAH and intracranial bleeds were the most common cause of death in both groups for deceased donor renal transplantation. Incidence of suicide as cause of death in deceased donors is rising in males.
