PURPOSE: Tailoring perioperative management to minimize the postoperative complication rates depends on reliable prognostication of patients most at risk. The Surgical Apgar Score is an objective measure of the operative course validated to predict major complications and death after general/vascular surgery. We assessed the ability of the Surgical Apgar Score to identify patients most at risk for postoperative morbidity and mortality after renal mass excision. MATERIALS AND METHODS: Data for 886 patients undergoing renal mass excision via radical or partial nephrectomy from 2010 to 2013 were extracted from a prospectively collected database. The Surgical Apgar Score was calculated using electronic anesthesia records. Major postoperative complications, readmission and reoperation within 30 days of surgery as well as 90-day mortality were examined. RESULTS: Overall 13.2% of patients experienced major postoperative complications at 30 days. Clavien grade I, II, III, IV and V complications were experienced by 1.7%, 2.9%, 5.8%, 1.9% and 0.9%, respectively. The 90-day all cause mortality rate was 1.4%. The Surgical Apgar Score was significantly lower in patients experiencing major complications (mean 7.3 vs 7.8, p=0.004) and death (6.3 vs 7.7, p=0.03). Patients with a Surgical Apgar Score of 4 or less were 3.7 times more likely to experience a major complication (p=0.01) and 24 times more likely to die within 90 days of surgery (p=0.0007) compared to patients with a Surgical Apgar Score greater than 8. CONCLUSIONS: The Surgical Apgar Score is an easily collected metric that can identify patients at higher risk for major complications and death after renal mass excision. A prospective trial to help further delineate the optimal use of this tool in an adjusted perioperative management approach with patients undergoing renal mass excision is warranted.
