Why the study?

Does the accumulated experience of an academic cardiac surgeon over a 10-year period reduce operative morbidity and mortality?

Structured PICO

Does the accumulated experience of an academic cardiac surgeon over a 10-year period reduce operative morbidity and mortality?

Population

1,347 consecutive and unselected patients undergoing cardiac surgical operations from October 1988 to September 1998

Intervention

Cardiac surgical operations performed by an academic cardiac surgeon over a 10-year period (grouped into five 2-year blocks)

Comparator

Earlier vs. later periods of practice (periods 1 to 5)

Outcome

Operative mortality rate and standardized definitions of perioperative myocardial infarction, intra-aortic balloon pump use, reoperation for bleeding, stroke, sternal wound complications, sepsis, and respiratory insufficiencyhard clinical

Operative mortality and select morbidity rates after cardiac surgery improve linearly over the first 10 years of independent practice, and the CUSUM method is a valuable tool for prospective quality control.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Surgeon experience was associated with lower CABG mortality and MI; hypothesis-generating and leaves generalizability open.
