OBJECTIVES: To estimate re-hospitalization and bleeding during the 30 days after a venous thromboembolism (VTE) event in patients following hip fracture surgery and to compare the outcomes with patients without VTE. METHODS: Based on 2005-2007 national Medicare claims, all patients who underwent hip fracture surgery were identified. The 30 days follow-up event rates for patients who had a VTE event during their initial hospitalization were calculated. Events were compared between patients who suffered a VTE event and those who did not. Risk adjustment was done using propensity score matching controlling for baseline demographic and clinical characteristics between patients with and without VTE. RESULTS: In patients who underwent hip fracture surgery (n=50,245), 1.5% had post-operative VTE during their initial hospitalization.  Almost 77% (n=573) of these patients had deep vein thrombosis (DVT), 20% (n=141) had a pulmonary embolism (PE), and 3% (n=34) had both DVT and PE.  Patients with VTE during their initial hospitalization were more likely to be hospitalized in 30 days (compared to patients without an event during the same hospital stay (32% vs. 6.82%).  In 30 days after the event, patients with VTE were more likely to have bleeding (10.65% vs. 0.68%). CONCLUSIONS: VTE events during initial hospitalization for hip fracture surgery patients increased the adverse events compared with no VTE events.
