Résumé
The aim of this study is to evaluate the use of thromboprophylaxis in surgical oncology patients in HCUCH in 2011. Method: Retrospective analysis of patients with cancer undergoing surgery in 2011. Was defined as adequate pharmacological thromboprophylaxis the correct dose, mechanical prophylaxis in case of drug contraindications and beginning on day 0 or 1. Results: 131 medical records were reviewed. Main neoplasms were colorectal (21.3 percent), prostate (12.9 percent), gallbladder (8.3 percent) and stomach (6.9 percent). Of the patients requiring pharmacologic thromboprophylaxis (n = 110) were rated as adequate 52 patients (47 percent), 47 inadequate (43 percent) and 11 absent (10 percent). The causes of inappropriate use of pharmacological thromboprophylaxis included 27 late onset (58 percent), 10 lower doses (21 percent), 3 late onset associated with lower dose (6 percent), 6 incomplete thromboprophylaxis (13 percent) and 1 dose increased (2 percent). Factors significantly associated with pharmacological thromboprophylaxis absent were: <40 years of age (p = 0.002), head and neck cancer (p < 0.001), and hospital stay <7 days (p < 0.001). Conclusions: The absence of pharmacological thromboprophylaxis is associated with lower absolute risk factors for VTE: Age less than 40 years old, head and neck cancer, hospital stay less than 7 days...
