How this service works
Dakik 2019 AUB-HAS2 for 30-day death/MI/stroke after noncardiac surgery: six 1-point elements (history of heart disease, angina or dyspnea, age ≥75, hemoglobin <12 g/dL, vascular surgery, emergency surgery). Low 0-1, intermediate 2-3, high >3 (max 6). Derivation rates 0%, 0.5%, 2.0%, 5.6%, 15.7% by score 0/1/2/3/>3. Not a medical device, not RCRI, not ACS treatment, and not operative clearance.
Output
Returns the computed AUB-HAS2 total score (0–6), the corresponding risk category (low: 0–1, intermediate: 2–3, high: >3), and the derivation-cohort event rates associated with each score level (0%/0.5%/2.0%/5.6%/15.7% for scores 0/1/2/3/>3).
Example use cases
Preoperative risk stratification for vascular surgery
“I have a 78-year-old patient with a history of heart disease, no angina or dyspnea, hemoglobin of 13.2 g/dL, scheduled for elective vascular surgery — can you compute their AUB-HAS2 score and tell me whether they're low, intermediate, or high risk?”
Emergency surgery cardiac risk assessment
“A 68-year-old patient with no history of heart disease and no angina is going into emergency abdominal surgery tonight — hemoglobin is 11.8 g/dL, not a vascular case. What's their AUB-HAS2 score and risk category?”
Low-risk preop screening for young patient
“My patient is 62, no cardiac history, no angina or dyspnea, hemoglobin 14.5 g/dL, elective non-vascular surgery, not an emergency. Can you run the Dakik 2019 AUB-HAS2 calculation and confirm they're in the low-risk group?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/aub_has2When to prefer
Use this endpoint when you need to apply the specific Dakik 2019 AUB-HAS2 six-element scoring algorithm for 30-day MACE risk after noncardiac surgery; prefer it over RCRI-based tools when the clinical context matches the Dakik 2019 derivation cohort or when you need AUB-HAS2 specifically rather than a generic perioperative risk score.
Side effects
- Missing required boolean flags (history_of_heart_disease, angina_or_dyspnea, vascular_surgery, emergency_surgery) returns a validation error
- Age outside range 18–120 rejected with parameter error
- Providing both hemoglobin_g_dl and hemoglobin_g_l simultaneously causes a conflict error
- Hemoglobin value outside valid range (3–22 g/dL or 30–220 g/L) rejected
- Non-integer age value rejected
