Why the study?
Do hospital- and surgeon-specific factors affect in-hospital mortality rates in patients undergoing CABG surgery?
Do hospital- and surgeon-specific factors affect in-hospital mortality rates in patients undergoing CABG surgery?
Significant variations exist in surgeon- and hospital-specific in-hospital mortality rates for CABG that are not fully explained by patient illness severity or procedural volume.
No takes yet. Share an insight, caveat, or question.
Surgeon- and hospital-level CABG mortality variations merit monitoring; leaves open identification of modifiable factors in prospective studies.
Sankey V. Williams (1991) studied this question.
