Increasing Organ Donation and Transplantation: The Challenge of Evaluation. 2. Referral Rate


The second step of the retrieval process is the referral of a potential donor to an OPO. The referral rate is the number of potential donors referred to an OPO divided by either total potential donors (determined by MRR) or by total identified donors (determined from hospital data).

  • The referral rate can be used to evaluate the effectiveness of Required Referral and Required Request legislation. Although the intent of such legislation is to increase donation by involving expert OPO staff more frequently and earlier in the donation process, it is referral rate, rather than donation rate, that best indicates the impact of the legislation.
