Organ donation in suicides.

INTRODUCTION

There are few reports in the literature analyzing brain death epidemiology in suicides, or the rate of donation and family authorization in such situations.

OBJECTIVE

The objectives of this study were to analyze the frequency of suicide as a cause of brain death and to compare the donation rates among this population with other causes of brain death.

PATIENTS AND

METHODS

We reviewed records from 2627 potential donors between 1988 and 2004.

RESULTS

Within that period, 101 (3.8%) cases of brain death were recorded as suicides. The mean age was significantly lower (P < .05) in cases of suicide than for other causes (26.2 + 11.1 vs 34.4 + 16.5 years); there was a male prevalence (76.2% vs 60.8%). As to suicides, the donation rate was significantly higher than in other situations (62.3% vs 43.8%). This was due to a lower rate of negative family responses (17.8% vs 32.1%).

CONCLUSIONS

Suicide is a frequent cause of brain death (3.8%), mainly among young men. The donation rate in this group is higher than that due to other causes of death because of a lower negative response rate by the family. The explanation remains to be clarified for such a low refusal rate for organ donation by the relatives of potential donors due to suicide.
