Overview

Observational volume-mortality associations should not yet change referrals; leaves open need for prospective confirmation of causality.

Structured PICO

Does higher hospital and physician procedure volume reduce in-hospital mortality rates for surgical procedures in New York State Hospitals?

P
Population
Patients undergoing surgical procedures (total cholecystectomies, coronary artery bypass surgeries, resection of abdominal aortic aneurysms, partial gastrectomies, and colectomies) in New York State Hospitals
I
Intervention
High hospital and physician procedure volume
C
Comparator
Low hospital and physician procedure volume
O
Outcome
In-hospital mortality rateshard clinical

Higher physician and hospital procedure volumes are significantly associated with lower in-hospital mortality for several major surgeries, with physician volume being particularly important for procedures like CABG and AAA resections.
