How this service works
Douketis 2022 ACCP elective perioperative DOAC interruption (PAUSE-style, recommendations 22-25). Returns hold_days_before and resume_days_after from INN (apixaban, rivaroxaban, edoxaban, dabigatran) and bleed_risk. dabigatran also needs caller-assigned CrCl. heparin_bridge is always false (recommendation 26). Not warfarin, not urgent surgery, not a prescription. magent does not assay CrCl.
Output
Returns hold_days_before (number of days to stop the DOAC prior to surgery) and resume_days_after (number of days post-procedure before restarting), plus heparin_bridge (always false per recommendation 26). Specific to the given DOAC and bleed risk tier, with dabigatran values further stratified by caller-supplied CrCl.
Example use cases
Elective knee replacement DOAC hold
“My patient takes rivaroxaban and is scheduled for an elective knee replacement, which is high bleed risk — per Douketis 2022, how many days before the operation should they stop rivaroxaban and when can they resume?”
Dabigatran hold with impaired renal function
“I need the perioperative DOAC interruption schedule for a patient on dabigatran with a CrCl of 40 mL/min going in for a low-to-moderate bleed-risk elective procedure — give me the hold and restart days from the ACCP PAUSE guidelines.”
Heparin bridge decision for edoxaban patient
“Do I need to bridge with heparin when holding edoxaban for an elective low-to-moderate bleed-risk surgery, and what are the recommended hold and resume days per Douketis 2022?”

Endpoint
GEThttps://api.magentlab.com/api/calc/periop_doacWhen to prefer
Use this endpoint when you need guideline-concordant PAUSE-style hold and restart day counts for elective procedures involving a DOAC (apixaban, rivaroxaban, edoxaban, or dabigatran) and you already know the procedure bleed risk category and, for dabigatran, the patient's CrCl. Prefer this over general anticoagulation references when you need a structured, machine-readable output aligned to Douketis 2022 ACCP recommendations 22-25. Do not use for warfarin, urgent surgery, or when CrCl needs to be computed.
Side effects
- Missing required bleed_risk parameter returns validation error
- crcl_ml_min provided for apixaban/rivaroxaban/edoxaban returns error (must be absent)
- crcl_ml_min absent for dabigatran returns error (required for that drug)
- crcl_ml_min outside 15-120 range may return validation error
- Invalid/unrecognized DOAC name returns error
- Warfarin or VKA submitted — endpoint does not support these agents
- Urgent or emergent surgery context not supported
