As I understand it, the Physicians’ Referral Service (PRS) was the brainchild of R. Lee Clark. It served as a repository for the clinical revenues generated by the clinical faculty and paid for many of the benefits for BOTH clinical and basic science faculty.
The benefits package when I arrived at MD Anderson in 1984 was the best in all of academic medicine. Even as the salaries here were more than competitive, the benefits package was superlative and abetted the recruitment and retention of many stellar faculty members over the years. PRS benefits were the golden handcuffs that kept our best faculty in Houston.
