PG - 3730-3740 LID - 10.1111/bcp.15314 [doi] AB - AIMS: Anticoagulants represent a main source of medication errors (MEs) and complications that have catastrophic implications, posing an obligation on health care providers to assess anticoagulant-related MEs and factors affecting their occurrence. This study investigates the occurrence and severity of prescribing MEs in patients on anticoagulants and explores their potential predictors. METHODS: This study was a prospective cohort study in a tertiary hospital on 116 patients with a total of 2166 anticoagulant doses. RESULTS: Forty-four percent of prescribed anticoagulant doses resulted in MEs with low molecular weight heparin (LMWH) and unfractionated heparin (UFH) causing 61% and 34%, respectively, of the total MEs. More than 50% of all MEs were incorrect doses (high and low) shared between heparin and tinzaparin. The highest severity of error was Category D followed by Category F and Category C. A Poisson regression analysis model revealed that female (incidence rate ratio [IRR] 1.32, 95% confidence interval [CI] 1.13-1.54, P < .001), bridging (IRR 1.52; 95% CI 1.10-2.09; P = .011), venous thromboembolism (VTE) prophylaxis (IRR 7.65; 95% CI 4.88-12.02; P < .001), physician non-adherence (IRR 2.71; 95% CI 2.22-3.29; P < .001), and polypharmacy (IRR 1.68; 95% CI 1.26-2.23; P = .036) were predictors of the higher incidence of MEs. Ordinal logistic regression analysis demonstrated that physician non-adherence (OR 24.67; 95% CI 5.54-207; P < .001) was the main predictor of increased error severity. CONCLUSION: The major predictor in increasing both the incidence and severity of MEs is physician adherence to evidence-based guidelines (EBG). Strict regulations for anticoagulant prescribing through an anticoagulant stewardship program are a necessity. CI - (c) 2022 British Pharmacological Society.
