Provider care team segregation and operative mortality following coronary artery bypass grafting.
The purpose of this study was to examine whether provider care team segregation within hospitals contributes to the higher mortality rate of Black patients following coronary artery bypass grafting compared to their White counterparts. Using national Medicare data, findings showed that Black patients who undergo coronary artery bypass grafting at a hospital with a higher level of provider care team segregation die more frequently after surgery than Black patients treated at a hospital with a lower level.

Assessment of mortality among durable left ventricular assist device recipients ineligible for clinical trials.
This study compared the mortality of heart patients undergoing durable left ventricular assist device (LVAD) implantation who were enrolled in a clinical trial called Multicenter Study of MagLev Technology in Patients Undergoing Mechanical Circulatory Therapy With HeartMate 3 (MOMENTUM 3) to general population LVAD recipients from 181 North American centers from January 1, 2012, to June 30, 2017, identified in the Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS). Among 14,679 recipients, a total of 6429 recipients (43.8%) would have been ineligible for enrollment in the MOMENTUM 3 study. Estimated mortality for recipients who were trial-ineligible was higher than for recipients who were trial-eligible (25.3% versus 16.2% for 1-year mortality, 42.8% versus 36.4% for 3-year mortality). The authors concluded that a better representation of the patient population would reflect real-world experience better than the trial eligibility criteria that was used.
