🧮 ACS-NSQIP Surgical Risk Calculator (framework)
The ACS-NSQIP Surgical Risk Calculator estimates 30-day postoperative outcomes from a procedure-specific (per-CPT) logistic model built on millions of operations. This page frames the required inputs and links to the official calculator rather than reproducing the proprietary computation.
The model is calibrated procedure-by-procedure and cannot be accurately reproduced outside the official tool; this page supplies inputs and the link only, never a fabricated risk value. (original synthesis · not guideline verbatim)

When to use
Use during informed consent and perioperative planning to discuss individualized risk of death, serious complications, and specific events. Enter the surgical CPT code plus 21 patient predictors in the official calculator; interpret alongside clinical judgment and institutional protocols.
How it works
Per-CPT proprietary logistic regression with 21 predictors → ~13–19 predicted 30-day outcomes (serious/any complication, pneumonia, cardiac event, SSI, UTI, VTE, renal failure, readmission, reoperation, discharge destination, death, length of stay).
Key points
- The model is calibrated procedure-by-procedure and cannot be accurately reproduced outside the official tool; this page supplies inputs and the link only, never a fabricated risk value. (original synthesis · not guideline verbatim)
- Required inputs include CPT code, age, sex, functional status, emergency status, ASA class, steroid use, ascites, sepsis, ventilator dependence, disseminated cancer, diabetes, hypertension, CHF, dyspnea, smoking, COPD, dialysis, acute renal failure, and BMI.
- Outputs support shared decision-making but do not replace surgical judgment or local guidelines.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.

- Nature：The ACS-NSQIP surgical risk calculator is built on millions of operations using complex per-CPT logistic models (21 predictors); it is proprietary and calibrated by procedure and cannot be accurately reproduced on this platform. This tool only lists the required inputs and the official link; it does not output fabricated risk values
- Required inputs (21)：Surgical CPT code; age group, sex, functional status (independent / partially / totally dependent), emergency case or not, ASA class, steroid use, ascites, preoperative sepsis, ventilator dependence, disseminated cancer, diabetes, hypertension requiring medication, congestive heart failure, dyspnea, smoking, COPD, dialysis, acute renal failure, BMI/height/weight
- Outputs (~13–19 items · 30-day)：Serious complication, any complication, pneumonia, cardiac event (MI/cardiac arrest), surgical site infection, urinary tract infection, venous thromboembolism, renal failure, readmission, reoperation, discharge destination, death, length of stay, etc.
