Organizational characteristics of intensive care units related to outcomes of abdominal aortic surgery.
Context Morbidity and mortality rates in intensive care units (ICUs) vary widely among institutions, but whether ICU structure and care processes affect these outcomes is unknown.
Objective To determine whether organizational characteristics of ICUs are related to clinical and economic outcomes for abdominal aortic surgery patients who typically receive care in an ICU.
Design Observational study, with patient data collected retrospectively and ICU data collected prospectively.
Setting All Maryland hospitals that performed abdominal aortic surgery from 1994 to 1996.
Patients and Participants We analyzed hospital discharge data for patients in non-federal acute care hospitals in Maryland who had a principal procedure code for abdominal aortic surgery from January 1994 through December 1996 (n=2987).
We obtained information about ICU organizational characteristics by surveying ICU medical directors at the 46 Maryland hospitals that performed abdominal aortic surgery.
Thirty-nine (85%) of the ICU directors completed this survey.
Main Outcome Measures In-hospital mortality and hospital and ICU length of stay.
Results For patients undergoing abdominal aortic surgery, in-hospital mortality varied among hospitals from 0% to 66%. (...)
