Authors' conclusion

Increased surgeon-anesthesiologist familiarity was associated with lower operative mortality and improved outcomes in cardiac surgery, highlighting the importance of consistent team collaboration.

Study context

Population
Cardiac surgery cases at a large academic medical center, July 2011 to January 2024481 unique dyads
Participants
16,811 cases
Exposure
Lowest- vs highest-familiarity surgeon–anesthesiologist dyads
Outcome
Operative mortality (death before discharge or within 30 days post-procedure)
Methodological detailssingle-centre, logistic mixed-effects model

As reported in the abstract

Higher dyad familiarity associated with significantly lower operative mortality, entire cohort
P < 0.001

Observational data: associations, not effects.

Secondary outcomes

Reduced rates of several adverse outcomes with higher-familiarity dyads
Deep sternal wound infection showed no association with dyad familiarity
