BACKGROUND: Hospitalized medically ill patients are at greater risk for venous thromboembolism (VTE). Although pharmacologic prophylaxis regimens have reduced VTE risk in medically ill patients, associations with early postdischarge adverse clinical outcomes among patients with heart failure are unknown. HYPOTHESIS: We hypothesized that patients receiving pharmacologic VTE prophylaxis during hospitalization for heart failure would have lower rates of postdischarge adverse clinical outcomes than patients not receiving prophylaxis. METHODS: Using data from the Acute Decompensated Heart Failure (ADHERE) registry linked to Medicare claims, we estimated 30-day postdischarge outcome rates for patients who received in-hospital subcutaneous heparin compared with patients who did not receive in-hospital VTE prophylaxis. We excluded patients who received warfarin or intravenous heparin. Outcomes included mortality, thromboembolic events, major adverse cardiovascular events, and all-cause readmission. We used propensity-score methods to estimate associations between VTE prophylaxis and each outcome. In a secondary analysis, we compared outcomes of patients receiving pharmacologic prophylaxis with unfractionated heparin (UFH) vs low-molecular-weight heparin (LMWH). RESULTS: Of 36 799 eligible patients in 265 hospitals, 12 169 (33%) received pharmacologic VTE prophylaxis during the hospitalization. In unadjusted analysis and after weighting by the inverse probability of treatment, VTE prophylaxis was not associated with 30-day postdischarge mortality, thromboembolic events, major adverse cardiovascular events, or all-cause readmission. There were no differences in outcomes between patients receiving UFH and those receiving LMWH. CONCLUSIONS: Pharmacologic VTE prophylaxis is provided to one-third of older patients hospitalized with heart failure. Treatment with LMWH or UFH did not have a statistically significant association with 30-day postdischarge outcomes.
