PS58 Changes in and Factors Affecting Failure to Rescue Mortality After Elective Abdominal Aortic Aneurysm Repair: 1995-2011

1.3; 1.1-1.6; P 1⁄4 .01) and diabetes (odds ratio, 1.2; 1.11.5; P < .05). Admission urgency and surgery class (aortic, peripheral vascular, carotid or endovascular) did not predict AKI. AKI patients had higher mortality (inpatient: 20% vs 1%, 1-year: 34% vs 14%; P < .01 both). Among AKI patients, mortality was increased even for mild renal dysfunction (1-year mortality: risk 33% vs injury/failure 36%; P 1⁄4 .79). With AKI, lengths of stay were longer (SICU: 8 6 8 vs 4 6 2 days; hospital: 20 6 15 vs 11 6 8 days; P < .001) and discharge Cr was higher (1.47 6 1.15 vs 0.92 6 0.49 mg/dL; P < .001). Conclusions: AKI is common among vascular surgery patients requiring SICU admission, regardless of admission status or surgery class. All severities of renal dysfunction are associated with significantly worse outcomes. Further study with identification of early, modifiable risk factors, particularly in elective surgery patients, may prevent AKI and improve outcomes.
