How this service works
Aggarwal 2023 DOAC Score (Circulation Table 2) for AF on DOACs: age 65-69 2 / 70-74 3 / 75-79 4 / >=80 5 (<65 0); CrCl/eGFR 30-60 inclusive 1, <30 2; underweight caller BMI <18.5 flag 1; stroke/TIA/embolism 1; diabetes 1; hypertension 1; antiplatelet none 0, aspirin 2, dual 3; NSAID 1; bleeding history 3; liver disease 2. Score min(raw, 10). Bands 0-3 very_low, 4-5 low, 6-7 moderate, 8-9 high, 10 very_high. Not HAS-BLED. Not DOAC dosing. Not warfarin.
Output
Returns the integer DOAC raw score, the capped score (capped at 10), and a risk band string: very_low (0–3), low (4–5), moderate (6–7), high (8–9), or very_high (10). This is a pure computation result based on caller-supplied clinical flags; the API does not perform lab assays, BMI computation, or dosing recommendations.
Example use cases
Pre-prescription bleeding risk check
“Before starting apixaban for my 78-year-old AF patient with a CrCl of 35 mL/min, hypertension, diabetes, and a prior GI bleed, can you run the Aggarwal 2023 DOAC score? No liver disease, not underweight, no stroke history, no NSAIDs, and on aspirin only.”
Elderly patient with dual antiplatelet use
“My 82-year-old AF patient is on dual antiplatelet therapy (aspirin plus clopidogrel), has hypertension, CrCl of 28 mL/min, and no bleeding history, liver disease, diabetes, stroke history, NSAIDs, or underweight status — calculate the DOAC bleeding score and tell me the risk level.”
Low-risk younger AF patient screening
“Can you compute the Aggarwal DOAC bleeding score for a 66-year-old with no comorbidities — CrCl 85 mL/min, not underweight, no antiplatelet use, no NSAIDs, no bleeding history, no liver disease, no stroke, no diabetes, no hypertension — just want to confirm they're very low risk before starting a DOAC.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/doac_scoreWhen to prefer
Use this endpoint when you need to compute the Aggarwal 2023 DOAC bleeding risk score specifically for AF patients on DOACs — not HAS-BLED, not warfarin, and not a dosing calculator. Prefer this over HAS-BLED when the clinical context is specifically DOAC-based anticoagulation in AF per the 2023 Circulation publication. All clinical flag assignments (underweight, liver disease, bleeding history) must be made by the calling clinician; the API performs only arithmetic.
Side effects
- Missing required query parameters (age, crcl_or_egfr_ml_min, antiplatelet, and boolean flags) returns a 400 or validation error
- Age outside 18–120 range may be rejected
- CrCl/eGFR outside 5–200 mL/min range may be rejected
- Invalid antiplatelet enum value (not none/aspirin/dual) causes a 422 or error
- Payment failure (402 Payment Required) if x402 USDC micropayment not completed
- Network or server errors return 5xx
