ACE Clinical Guidances (ACGs)

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.
