Implication

Anaesthetist variation contributes negligibly to cardiac surgery mortality; leaves open effects on morbidity and very low caseloads.

Structured PICO

Does the individual anaesthetist affect risk-adjusted mortality after cardiac surgery?

P
Population
110,769 cardiac surgical procedures for which the EuroSCORE model is appropriate, conducted between April 2002 and March 2012 across ten UK centres, involving 127 consultant surgeons and 190 consultant anaesthetists.
I
Intervention
Individual anaesthetist care during cardiac surgery
O
Outcome
In-hospital death up to three months postoperativelyhard clinical

Mortality after cardiac surgery is overwhelmingly determined by patient baseline risk and moderately by the surgeon, with the individual anaesthetist having a negligible impact on survival.

Limitations

  • Does not establish potential effects of very low anaesthetic caseloads
  • Does not assess the effect of cardiac anaesthetists on patient morbidity
