Beginning with the January 2012 public release, Table 4 of the OPO-specific reports contained measures of expected donor yield using the models approved by the OPTN/UNOS Board in June 2011. The heart, liver, lung, and pancreas models used the lung pO2 terminal value as one of the modeling covariates. In the January and July 2013 reports, this covariate will be changed to the lung pO2 terminal value divided by the FiO2 value. This change is in response to OPO feedback indicating that the ratio would be more appropriate.

Beginning with the January 2012 public release, Table 4 of the OPO-specific reports will contain measures of expected donor yield using the models approved by the OPTN/UNOS Board in June 2011 and by the OPTN Membership and Professional Standards Committee in October 2011.

The OPO-specific reports privately released on the SRTR secure websites on December 8 will also include measures of observed and expected donor yield and whether the OPO meets the review criteria established by the OPTN’s OPO and Membership and Professional Standards Committees. The SRTR will be releasing a Donor Yield Calculator tool that OPOs can use to track observed and expected donor yield. The tool will be made available for download on the secure websites on December 8, 2011.
