Abstract
Introduction: In the absence of a patient's last direct oral anticoagulant (DOAC) dose time, best practice regarding preoperative DOAC cessation remains unclear. The aim of this study was to investigate, in a real-life patient cohort, if there was an association between subjective patient recall and objective DOAC assay titre.
Methods/materials: A multicentre cohort study of consecutive surgical inpatients was conducted. DOAC assays were 'expected' if they satisfied both time and titre-based guidelines.
Results: Patient-recalled last dose and DOAC assay was available in 285 individuals. DOAC assay titres correlated strongly with the expected levels based on a patient's reported last dose time(rho = 0.70, P value < 0.0001). However, underweight (<50 kg; P = 0.0339) and elderly (>80 years; P = 0.0134) were more likely to have an unexpectedly high assay titre.
Conclusions: A significant portion (∼25%) of patients had unexpected DOAC titres. DOAC levels can be clinically impactful in a significant percentage of patients, particularly in elderly and/or underweight.
期刊介绍：
Blood Coagulation & Fibrinolysis is an international fully refereed journal that features review and original research articles on all clinical, laboratory and experimental aspects of haemostasis and thrombosis. The journal is devoted to publishing significant developments worldwide in the field of blood coagulation, fibrinolysis, thrombosis, platelets and the kininogen-kinin system, as well as dealing with those aspects of blood rheology relevant to haemostasis and the effects of drugs on haemostatic components
