Increasing Organ Donation and Transplantation: The Challenge of Evaluation. 3. Request Rate


The third step of the retrieval process is the request made by hospital or OPO staff of the potential donor’s family. The request rate is the number of potential donors whose families are asked to donate divided either by total potential donors (determined by MRR) or by total identified or referred potential donors (determined from OPO or hospital data).

  • The request rate can also be used to evaluate how well doctors and OPO staff respond to new Required Request legislation. While there are few intervening factors to make consent and donation themselves the primary measure of interest in an evaluation, the request rate, cross-referenced with these behaviors, is a useful tool for use in hospital and OPO-level quality review and intervention.
