The appropriateness of stroke\u2010prevention therapy at admission and discharge was evaluated using Australian guidelines. Factors associated with correcting inappropriate OAC therapy were identified using multiple logistic regression.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Among 902 patients, 47.1% (<jats:italic>n<\/jats:italic>\u2009=\u2009425) were receiving inappropriate OAC therapy at admission. The most common errors included lack of OAC therapy (58.6%, <jats:italic>n<\/jats:italic>\u2009=\u2009249) and underdosing of direct\u2010acting OACs (15.5%, <jats:italic>n<\/jats:italic>\u2009=\u200966). OAC therapy appropriateness at discharge was assessed for 844 patients; 73.8% were receiving appropriate therapy (versus 53.8% at admission (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001)). Specifically, 49.0% (<jats:italic>n<\/jats:italic>\u2009=\u2009191) of the admission therapy errors were corrected. Correction was more likely in patients admitted to the stroke (adjusted odds ratio [aOR]: 16.93, 95% CI: 1.31\u2013218.48) or cardiology wards (aOR: 4.10, 95% CI: 1.94\u20138.64), and if bleeding occurred during hospitalisation (aOR: 4.01, 95% CI: 1.07\u201314.99). Conversely, receiving rivaroxaban at admission (aOR: .23, 95% CI: .11\u2013.51) and having a medium or high bleeding risk (ORBIT score \u22653) (aOR: .46, 95% CI: .25\u2013.84) decreased the likelihood of correction.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Hospitalisation improved OAC therapy appropriateness; however, 51.0% of patients admitted with inappropriate therapy continued without correction.
