6-way kidney exchange: Al Roth should be proud

The BBC reports:

US doctors have carried out what is believed to be the world’s first simultaneous six-way kidney transplant…
The hospital has been one of the pioneers of this system which matches up several groups of people at one time. It aims to circumvent the problem of altruistic donors ending up in arbitrary allocation systems where only a single patient’s needs are served. The hospital has been carrying out these simultaneous transplants for three years: in 2005, the first triple procedure was performed, a year later, the first five-way.
