Regionalizing high-risk surgery by restricting care to high-volume centers of excellence is a quality-improvement strategy with intuitive appeal. Decades of research have shown that the highest-volume hospitals have better outcomes for major surgery.1 Accordingly, 3 prominent medical centers—Dartmouth-Hitchcock Medical Center, Johns Hopkins Medicine, and the University of Michigan—recently announced a “volume pledge” to restrict their own facilities and surgeons from performing any of 10 selected procedures unless they meet volume criteria.2,3 Apart from a voluntary pledge, other policy approaches to regionalization have included the refusal to reimburse low-volume facilities (as Medicare currently does for solid-organ transplants) and tiered insurance benefits (ie, reducing out-of-pocket payments at high-volume hospitals).
