Potential for organ donation in Victoria: an audit of hospital deaths.

OBJECTIVE

To determine the potential for organ donation in 12 Victorian hospitals.

DESIGN AND SETTING

Prospective audit of all deaths in 12 major public hospitals in the state of Victoria between January 2002 and October 2004.

MAIN OUTCOME MEASURES

Number of organ donors and potential organ donors (patients with brain death or likely to progress to brain death within 24 hours if supportive treatment continued), requests for organ donation and consents. Unrealised potential donors (organ donation not requested) were categorised by an independent panel of intensivists as category A (brain death formally diagnosed); B (brain death not formally diagnosed but criteria likely to be fulfilled); and C (potential to progress to brain death within 24 hours).

RESULTS

There were 17,230 deaths, 280 potential organ donors and 220 requests for organ donation. The 60 unrealised potential organ donors were classified as category A (3), B (17) and C (40). Consent rate was 53% to 65%, depending on the definition of potential donor (categories A, B and C or category A only). Consent rate was lower when discussions about organ donation were held by trainees or registrars (21%) than when specialists were present (57%) (P = 0.004). A maximum practically achievable organ donation rate for Victoria was estimated to be 15 to 17 donors per million population (current rate, 9 per million population).

CONCLUSIONS

The potential for organ donation in Victoria is limited by a small organ donor pool. There is potential to increase the number of organ donors by increasing the consent rate (lower than expected from public surveys), the identification of potential organ donors (particularly those likely to progress to brain death if supportive treatment is continued), and requests for organ donation.
