Factors associated with the inappropriate dosing of direct oral anticoagulants in multivariate analysis

Predictor variables	Odds ratio	95% confidence interval	P value
Outpatients (vs. inpatients)	2.87	1.53–5.62	< 0.001
HAS-BLED score*	1.87	1.42–2.51	< 0.001

*Odds ratio per point increase

Type of hospital visit (outpatients or inpatients), history of bleeding, myocardial infarction, cerebrovascular disease, polypharmacy, single antiplatelet therapy, CHADS₂ score, CHA₂DS₂-VASc score, and HAS-BLED score, which were factors associated (p < 0.1) with inappropriate direct oral anticoagulant prescription in univariate analysis, were included in multivariate logistic regression analysis with a stepwise procedure
