This may lead to frequent deviations from target international normalized ratio (INR) due to inter\u2010 and intra\u2010patient variability and may potentially result in adverse events including recurrent thromboembolism and life\u2010threatening hemorrhage.<\/jats:p><\/jats:sec><jats:sec><jats:title>Objectives<\/jats:title><jats:p>We aim to employ CURATE.AI, a small\u2010data, artificial intelligence\u2010derived platform that has been clinically validated in a range of indications, to optimize and guide warfarin dosing.<\/jats:p><\/jats:sec><jats:sec><jats:title>Patients\/methods<\/jats:title><jats:p>A personalized CURATE.AI response profile was generated using warfarin dose (inputs) and corresponding change in INR between two consecutive days (phenotypic outputs) and used to identify and recommend an optimal dose to achieve target treatment outcomes. CURATE.AI's predictive performance was then evaluated with a set of metrics that assessed both technical performance and clinical relevance.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results and conclusions<\/jats:title><jats:p>In this retrospective study of 127 patients, CURATE.AI fared better in terms of Percentage Absolute Prediction Error and Percentage Prediction Error of 20% compared to other models in the literature. It also had negligible underprediction bias, potentially translating into lower bleeding risk. Modeled potential time in therapeutic range with CURATE.AI was not significantly different from physician\u2010guided dosing, so it is on\u2010par yet provides a systematic approach to warfarin dosing, easing the mental\u2010burden on guesswork by physicians.<\/jats:p><jats:p>This study lays the groundwork for the prospective study of CURATE.AI as a clinical decision support system. CURATE.AI may facilitate the effective use of affordable warfarin with a well\u2010established safety profile, without the need for costly, new oral anticoagulants. This can have significant impact both on the individual and public health.<\/jats:p><\/jats:sec>","DOI":"10.1002\/btm2.10757","type":"journal-article","created":{"date-parts":[[2025,2,4]],"date-time":"2025-02-04T02:04:16Z","timestamp":1738634656000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["AI\u2010assisted warfarin dose optimisation with <scp>CURATE<\/scp>.<scp>AI<\/scp> for clinical impact: Retrospective data analysis"],"prefix":"10.1002","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6323-5275","authenticated-orcid":false,"given":"Tiffany Rui Xuan","family":"Gan","sequence":"first","affiliation":[{"name":"Division of Surgery Ng Teng Fong General Hospital  Singapore Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lester W.
