Estimate patient-specific odds of death, any complication, surgical site infection, and prolonged length of stay using the ACS NSQIP model, which pairs a CPT procedure code with twenty preoperative variables drawn from over five million operations.
| Outcome | Estimated risk |
|---|---|
| Any complication | 26.6% |
| Serious complication | 19.0% |
| Pneumonia | 4.3% |
| Cardiac complication | 2.9% |
| Surgical site infection | 12.1% |
| Urinary tract infection | 5.3% |
| Venous thromboembolism | 3.2% |
| Renal failure | 2.2% |
| Readmission | 24.2% |
| Return to OR | 13.3% |
| Death | 4.6% |
| Discharge to nursing facility | 19.0% |
| Length of stay (estimated) | 4.0 days |
This tool approximates the structure of the ACS NSQIP Universal Surgical Risk Calculator (Bilimoria KY, et al. J Am Coll Surg 2013;217(5):833-42), which is a set of logistic regression models over 21 preoperative factors. The full NSQIP coefficient tables are proprietary and are not published, so the estimates here are a transparent, documented approximation: a baseline log-odds per outcome adjusted by additive contributions for each risk factor and passed through the logistic function. They are for education only and must not be used for clinical decision-making.
For the official, validated estimates, use the ACS NSQIP Surgical Risk Calculator at riskcalculator.facs.org, which requires the specific CPT procedure code and returns the published model output.
