Induction Slow Oates

Oates: The Oates algorithm is used for the non-urgent induction of patients requiring an INR of between 2.0 and 3.0. It cannot be used for urgent induction or for those patients who have a baseline INR > 1.3 or in those taking amiodarone. Reference: Br.J.Haem 1998; Vol 101: 450-454.

Warfarin Induction protocols have been designed to initiate Warfarin treatment in patients who are not currently taking Warfarin.
Before commencing ensure that 1mg tablets and/or 0.5mg tablets selected.
The patient’s gender also needs to be added as on the 15th day of treatment the dosing is determined by INR and male/female gender.

Induction algorithms can be added one day after patient has started warfarin
