Interfacility transfer of Medicare beneficiaries with acute type a aortic dissection and regionalization of care in the United States.
Researchers investigated the hypothesis that regionalizing care at high-volume hospitals for acute type A aortic dissections will lower mortality. Operative mortality and long-term survival were compared for Medicare beneficiaries diagnosed with an acute type A aortic dissection who were transferred versus not transferred, underwent surgery at high-volume versus low-volume hospitals, and were rerouted versus not rerouted to a high-volume hospital for treatment. The researchers found that, despite delaying surgery, a regionalization policy that transfers patients to high-volume hospitals was associated with a 7.2% absolute risk reduction in operative mortality. They recommended that policymakers evaluate the feasibility and benefits of regionalizing the surgical treatment of acute type A aortic dissection in the United States.

Sex and race differences in the utilization and outcomes of coronary artery bypass grafting among Medicare beneficiaries, 1999-2014.
The authors sought to evaluate how the use of coronary artery bypass grafting (CABG) and its outcomes have evolved in different sex and racial subgroups. Using Medicare data, they found that women and black patients had persistently higher CABG mortality than men and white patients, respectively, despite greater declines over the time period. The authors conclude that these findings indicate progress, but further progress is needed.
