Interhospital variability in health care-associated infections and payments after durable ventricular assist device implant among Medicare beneficiaries.
The purpose of this study was to examine differences in durable ventricular assist device implantation infection rates and associated costs across hospitals. The researchers utilized clinical data for 8,688 patients who received primary durable ventricular assist devices from the Society of Thoracic Surgeons Interagency Registry for Mechanically Assisted Circulatory Support (Intermacs) hospitals (n = 120) and merged that data with post-implantation 90-day Medicare claims. The primary outcome included infections within 90 days of implantation and Medicare payments. The study found that 27.8% of patients developed 3982 identified infections. The median adjusted incidence of infections (per 100 patient-months) across hospitals was 14.3 and differed according to hospital. Total Medicare payments from implantation to 90 days were 9.0% more in high versus low infection tercile hospitals. The researchers concluded that health-care-associated infection rates post durable ventricular assist device implantation varied according to hospital and were associated with increased 90-day Medicare expenditures.

Determinants of hospital variability in perioperative red blood cell transfusions during coronary artery bypass graft surgery.
This observational cohort study’s objective was to identify to what extent distinguishing patient and procedural characteristics can explain center-level transfusion variation during coronary artery bypass grafting (CABG) surgery. The study used patients from the Perfusion Measures and Outcomes Registry from 43 adult cardiac surgical programs from July 2011 through June 2017. Of the 22,272 adult patients undergoing isolate CABG surgery using cardiopulmonary bypass, 7241 (32.5%) received at least 1 U allogeneic red blood cells. Patients who received transfusions were older (68 vs 64 years), were women (41.5% vs 15.9%), and had a lower body surface area, respectively. The majority of center-level transfusion variations could not be explained through models containing both patient and intraoperative factors.
