OBJECTIVE: This study examined anticoagulant use during and after a hospital encounter for venous thromboembolism (VTE), a transition of care largely uncharacterized in the literature.

METHODS: Adults with a VTE diagnosis code during a hospital encounter (emergency department [ED], observation area [OBS], or inpatient hospital [IP]) from January 2012 to August 2017 were identified in an electronic health records database. The first such hospital encounter was defined as the index VTE encounter. Patients were linked to a claims database and required to be continuously enrolled for six months before the index admission date through six months after the index discharge date. Anticoagulants administered during the index VTE encounter and filled on or within 30 days of discharge were summarized descriptively overall, and by the type of index VTE encounter (IP, No IP) and anticoagulants administered during the index VTE encounter.

RESULTS: Among 2,968 eligible patients, mean (SD) age was 64 (16) years, 51% were female, 67% had an IP index VTE encounter, and 77% received anticoagulation therapy during the index VTE encounter. In total, 60% filled a prescription order for anticoagulant within 30 days post-discharge. Of those who received a direct oral anticoagulant (DOAC), warfarin, or parenteral anticoagulant only during the index VTE encounter, 74%, 69%, and 34%, respectively, filled a prescription for the same anticoagulant post-discharge. Patients treated with a DOAC or warfarin during an ED or OBS VTE encounter without a subsequent inpatient hospitalization were more likely to remain on the same anticoagulation therapy post-discharge than those with an inpatient hospitalization (81% vs 69% for DOAC and 75% vs 68% for warfarin).

CONCLUSIONS: Many patients treated with anticoagulation therapy during a VTE hospital encounter did not fill a prescription for an anticoagulant within 30 days post-discharge, highlighting an opportunity for improved management of care transitions in this patient population.
