Notes:
- All patients commenced DOAC should have medications reviewed:
- Antiplatelets: consider stopping, unless clear indication to continue antiplatelet in combination with DOAC. Consider discussing with Cardiology, where appropriate.

DOAC contra-indicated or unsuitable at present:
Low Molecular Weight Heparin (LMWH):
Enoxaparin
- CrCl ≥30mL/min AND low risk of recurrence:
1.5mg/kg once daily by subcutaneous injection - CrCl ≥30mL/min AND additional risk factors (eg, obesity, cancer, recurrent VTE, symptomatic PE):
1mg/kg twice daily (12 hourly) by subcutaneous injection - CrCl <30mL/min:
1mg/kg once daily by subcutaneous injection
Maximum initiation dose of enoxaparin is 120mg. In patients who weigh >120kg, use 120mg twice daily (provided CrCl >30mL/min), and seek specialist haematology advice +/- monitoring of Xa levels.
Treatment Duration
Provoked PEs (transient/reversible risk factor)
- Discontinue anticoagulation after 3 months (6 months in active cancer)
Unprovoked or recurrent PEs:
- Continue anticoagulation for at least 6 months and refer to PE clinic
Follow-up
Patients who should be referred to the PE service for follow-up include:
- All patients under the age of 50 with PE
- All unprovoked PE
- Recurrent PE
- All intermediate-high and high risk PE, as determined by the Risk Stratification above
Treatment duration >6 months may be appropriate for high risk / recurrent PE patients. Final decision will be made at PE clinic.
