ACE Clinical Guidances (ACGs)

ACGs* provide concise, evidence-based recommendations to inform specific areas of clinical practice and serve as a common starting point nationally for clinical decision-making. ACGs are underpinned by a wide array of considerations contextualised to Singapore, based on best available evidence at the time of development. Each ACG is developed in collaboration with a multidisciplinary group of local experts representing relevant specialties and practice settings. ACGs are not exhaustive of the subject matter and do not replace clinical judgement. 

Registered doctors, pharmacists and nurses may claim 1 Continuing Medical Education (CME)/Continuing Professional Education (CPE) point under category 3A/ Category V-B for reading each ACG.

This ACE Clinical Guidance (ACG) provides evidence-based recommendations on selecting an appropriate anticoagulant and treatment duration for different patient groups with venous thromboembolism (VTE), such as patients from the general population (including those with severe renal impairment or liver disease) and those with active cancer. Guidance on when to extend therapy is also provided.

A supplementary guide on switching between anticoagulants is included.

First published in 2018, the ACG on VTE treatment has been updated to incorporate the latest evidence where relevant.

ACG recommendations
1.Start anticoagulation as soon as possible for patients with confirmed proximal DVT or PE, unless contraindicated. 
2.For patients from the general population, use a DOAC for at least 3 months as the preferred anticoagulant for VTE treatment; consider warfarin as an alternative if DOACs are not suitable.
3.For patients with cancer needing VTE treatment, use apixaban, edoxaban, rivaroxaban, or LMWH for the initial and treatment phases for at least 6 months; LMWH is preferred if the patient has gastrointestinal cancer.
