Purpose: Venous thromboembolism (VTE), including deep venous thrombosis (DVT) and pulmonary embolism, is a common cause of morbidity and mortality after radical cystectomy. The purpose of our study was to evaluate the utility of extended outpatient chemoprophylaxis against VTE after radical cystectomy—with a focus on any reduction in the incidence of VTE, including DVT and pulmonary embolism. Materials and methods: Beginning in April 2013, we prospectively instituted a policy of extending inpatient VTE prophylaxis with subcutaneous heparin/enoxaparin for 30 days postoperatively. For this study, we reviewed the electronic medical records of all patients who underwent radical cystectomy at our institution from January 2012 through December 2015. The experimental group (n = 79) received extended outpatient chemoprophylaxis against VTE; the control group (n = 51) received no chemoprophylaxis after discharge. The primary outcome was the 90-day incidence of VTE. The secondary outcomes included the overall complication rate, the hemorrhagic complication rate, as well as the rate of readmission within 30 days of hospital discharge. Results: The experimental group experienced a significantly lower rate of DVT (5.06%), assessed as of 90 days postoperatively, than the control group (17.6%): a relative risk reduction of 71.3% (P = 0.021). We found no significant differences in secondary outcomes between the 2 groups, including the overall complication rate (54.4% vs. 68.6%), the hemorrhagic complication rate (3.7% vs. 2.0%), and the readmission rate (21.5% vs. 29.4%). Conclusion: Extended outpatient chemoprophylaxis significantly reduced the incidence of VTE.
