Baskin-Bey et al developed a Recipient Renal Score (RSS) for predicting survival following transplantation of a deceased donor kidney. This can help match recipients with donor kidneys prior to transplantation. The authors are from the Mayo Clinic in Rochester.
Parameters:
(1) diabetes mellitus
(2) age in decades with or without diabetes
(3) duration of dialysis in years
(4) history of angina

RRS =
= SUM(points for all 4 parameters)
Interpretation:
• The lower the RRS the healthier the recipient and the better the survival.
• Allocation is based on good donor kidneys going to someone likely to live longer and marginal kidneys to go to someone with a short life expectancy.
