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.

Association between postoperative pneumonia and 90-day episode payments and outcomes among Medicare beneficiaries undergoing cardiac surgery.
Postoperative pneumonia is the most common healthcare-associated infection in cardiac surgical patients, yet their impact across a 90-day episode of care remains unknown. The objective of this study was to examine the relationship between pneumonia and 90-day episode payments and outcomes among Medicare beneficiaries undergoing cardiac surgery. The investigators concluded that postoperative pneumonia was associated with significantly higher 90-day episode payments and inferior outcomes at the patient and hospital level.
