Summary
On December 23, 2019, the US Centers for Medicare and Medicaid Services proposed 2 new standards that organ procurement organizations (OPOs) must meet for recertification.
We examined how OPOs would have fared under the proposed performance standards in 2016-2017.
We conclude that the proposed new standards may result in over half of OPOs facing decertification, and risk adjustment suggests that underlying characteristics of deaths vary regionally such that decertification decisions may be affected.
Therefore, the overall 75th quantile will be too low for small OPOs and too high for large OPOs.

Summary
Objective is to evaluate OPO performance metrics using combined mortality and donation data and quantify the associations of population demographics with donation metrics.
We demonstrate significant variability in OPO performance rankings, depending on which donation metric is used.
The performance of OPOs should be evaluated using a range of donation metrics.

Summary
Historically, deceased organ donation was lower among Black compared with White populations, motivating efforts to reduce racial disparities.
The study objective is to examine changes in deceased organ donation over time.
The findings of this cohort study suggest that differences in deceased organ donation between White and some racial minority populations have attenuated over time.
Despite improvements, substantial differences remain, suggesting that novel approaches are needed to understand and address relatively lower rates of deceased organ donation among all racial minorities.
