Interesting point made on here earlier regarding the use of the above leading to confusion and ambiguity. When I was in hospital earlier this year the admitting medic wrote NOAC in the key information section on my medication administration chart as I was on Rivaroxaban.
When the registered nurse did a drug round she asked me why I was on no anticoagulants when I had Paroxysmal Atrial Fibrillation! This was her interpretation of NOAC! On reflection this could have been extremely dangerous if I had been admitted incoherent or unconscious. I think DOAC should be universally adopted or maybe don't use abbreviations for critical medications??
