Obtaining Consent for Organ Donation in Nine NSW Metropolitan Hospitals

Abstract

Organ donation rates vary markedly around the world. In an attempt to analyse why some patients’ families are not asked about organ donation, the case notes of 6080 patients who died over a twelve-month period from April 1991 to March 1992 in nine hospitals in Sydney, NSW, were studied. Irreversible coma occurred in 515 patients. Of these, 177 were considered to be potentially brain dead donors, 126 of whom had a formal diagnosis of brain death. The clinicians caring for the patients at the time of death were asked at follow-up about the reasons for not considering donation, or the reasons for family refusal. Consent to proceed to organ donation was requested in 112 cases (49 donated and 63 refused) and not requested in 65. Analysis of the proportions asked and consenting in each hospital revealed no correlation. Half of the families refusing gave no reason (24/50) while eleven gave religious or cultural reasons, and six expressed a desire to prevent mutilation of the body as their primary reason for not consenting. There was universal failure to gain consent from families when the patient was not in an Intensive Care Unit. Analysis of those patients of whom consent was not sought showed that they died more quickly after admission, were older and died from causes other than trauma or intracranial haemorrhage. The odds of the family being asked dropped by about half as the age increased from one group to the next. Increases in organ donation may be achieved by ensuring that potential donors reach intensive care units; that criteria for medical suitability for donation are unambiguous and widely known; and that changes occur in public attitudes to consent for donation.
