Abbreviated risk classifier derived from ACS NSQIP neurosurgery morbidity trends.
Surgical Morbidity Probe
Calculate the 30-day perioperative morbidity risk based on patient physiology and intended neurosurgical footprint.

When to Use
When to Use
Counseling patients on the 30-day risk of death, pneumonia, re-operation, or venous thromboembolism.
Identifying high-frailty patients who should be directed to conservative management rather than high-morbidity deformity correction.
Section 2
Literature
Development
The American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) developed an exhaustive, data-driven logistic regression model derived from millions of surgical cases. This specific abstraction focuses on the highest-weight covariates (ASA, functional status, age) that govern neurosurgical decision making in daily clinic.
Section 3
Pearls/Pitfalls
The Power of Functional Status
Age alone is a weak predictor. NSQIP data heavily demonstrated that a 50-year-old totally dependent patient (nursing home) has a vastly higher 30-day mortality risk for a spine fusion than a robust, functionally independent 80-year-old bridging the concept of frailty into modern risk mapping.
