Structured PICO

Does a statewide quality improvement program based on data collection and dissemination reduce in-hospital mortality for patients undergoing CABG surgery?

P
Population
57,187 patients undergoing isolated CABG surgery discharged from all 30 New York State hospitals between 1989 and 1992.
I
Intervention
Statewide quality improvement program involving collection, analysis, and dissemination of risk-adjusted mortality and complication data for CABG surgery.
C
Comparator
Historical baseline (1989 outcomes compared to 1992 outcomes).
O
Outcome
Actual, expected, and risk-adjusted in-hospital mortality.hard clinical

A statewide quality improvement program collecting and disseminating risk-adjusted CABG mortality data was associated with a 41% reduction in risk-adjusted in-hospital mortality over 4 years.
