Factors Associated With the Choice of Oral Anticoagulant Class in the Older Patients: An Observational Study.

Direct oral anticoagulants are the drugs of choice for anticoagulant treatment, including in older adults. The female gender and the initiation during hospital stay increased the chances of being prescribed a direct oral anticoagulant in older adults. Stage 4 and 5 chronic kidney disease increased the likelihood of having a vitamin K antagonist prescribed. Our study also revealed a persistence of potentially inappropriate oral anticoagulant prescriptions in older patients.
