Model Scope/Population: Primary minimally invasive bariatric procedures (Sleeve, RYGB, DS/SADI) in adults ≥18 years. Not validated for open procedures, revisions, or non-bariatric surgery.
Outcome Definition: Primary endpoint is post-discharge PE diagnosed through day 30 (MBSAQIP definition). Secondary VTE estimate is PE or DVT requiring therapy.
Temporal: Model trained on 2020-2024 data. Performance may degrade over time.
Modeling/Statistical: Logistic regression with categorical bins. Individual predictions have uncertainty; population-level calibration expected.
Input Handling: Age bins (<40, 40-49*, 50-59, 60-69, ≥70); BMI bins (<35, 35-44.9*, 45-54.9, 55-64.9, ≥65); OR Time (<60, 60-90*, 90-120, 120-150, ≥150 min); LOS (0-1*, 2, 3-4, ≥5 days). *Reference categories.
Clinical Action: Risk estimates should be integrated with patient preferences, contraindications, and bleeding risk. Not prescriptive.
Bleeding Risk Not Modeled: Extended thromboprophylaxis carries bleeding risk not captured here. Individualized assessment required.
Comparative/Baseline: PE and VTE estimates are displayed separately because their absolute risks are not interchangeable. Individual risk varies widely.
Regulatory/Legal: For research and decision support only. Not FDA-cleared. Clinicians retain full responsibility.

Model Scope/Population: Post-discharge patients after minimally invasive bariatric surgery presenting to ED or requiring IV hydration within 30 days.
Clinical Action: Reassess PE risk immediately. Consider extended thromboprophylaxis based on high-risk modifiers.
Bleeding Risk: Extended prophylaxis carries bleeding risk—individualized assessment required.
Regulatory: For decision support only. Clinicians retain full responsibility.

Step 1: Event Recognition
Patient has experienced:
- Post-discharge ED visit within 30 days, OR
- Outpatient IV hydration within 30 days
Interpretation: Patient has transitioned into a higher-risk postoperative state, independent of discharge-level risk.
Action: Reassess PE risk immediately.
Step 2: High-Risk Modifier Assessment

Model Scope/Population: Post-discharge patients experiencing severe complications (readmission, reoperation, sepsis, organ-space infection).
Clinical Action: Extended thromboprophylaxis strongly recommended at discharge due to sustained physiologic stress.
