Popoola VO, et al. - A retrospective cohort study is performed to ascertain whether non-administration of parenteral venous thromboembolism (VTE) prophylaxis is more frequent than other prophylactic or treatment medications. Subcutaneous VTE prophylaxis is not administered more frequently than oral infectious diseases or cardiac prophylaxis and treatment medications. This information proposes that availability of an oral medication could improve the efficacy of VTE prophylaxis in real-world settings.
