Lower rate of family refusal for organ donation in non-heart-beating versus brain-dead donors.

Introduction: Family refusal is an important factor that limits the number of organ donors. Cultural and religious factors as well as perception of brain death are the principal reasons for these refusals. We examined whether the type of potential donor, that is brain-dead or non-heart-beating, had an influence on family refusal. In July 2005, we initiated a program of non-heart-beating donors who had died in the street or at home.

Materials And Methods: We compared family refusals among these potential donors with those among potential brain-dead donors from July 2005 to October 2008.

Results: The mean time of stay in the hospital was significantly greater for brain-dead donors than those who were non-heart-beating: 4 +/- 2 versus 0.23 +/- 0.01 days (P < .01). The rate of family refusals was significantly greater among the families of potential brain-dead donors, that is 24% (24/99) than non-heart-beating donors, that is, 4% (2/47; P < .01). Donor age was similar in both groups.

Conclusion: The rate of family refusals among potential non-heart-beating donors was significantly lower than that among families of brain-dead individuals. Greater understanding of death because the heart is not beating, less time of uncertainty about death, and shorter hospital stay could explain this difference.
