RESUMEN
INTRODUCTION: The French Agency for Health Safety of Products published recommendations of good practices (RGP) for the treatment of venous thromboembolic disease in 2009. Four of these recommendations apply to the initial management of the disease, with the objective of this study is to determine whether the development and diffusion of the four RGP has had an impact on the practice. METHODS: A retrospective before/after study comparing 132 patients treated in emergency department of the Civil Hospices of Lyon for pulmonary embolism (PE) and/or deep venous thrombosis (DVT) in 2008-2009 ("before") and 153 patients in 2010-2011 ("after"). RESULTS: In the "before" period, 70 patients were treated for DVT and 62 patients for PE. In the "after" period, 50 patients were treated for DVT and 103 patients for PE. The compliance rate was not significantly different for the two periods for each RGP except for the indication of low molecular weight Heparin (LMWH) or fondaparinux in the absence of severe renal failure (21% "before" vs. 45% "after"; P=0.02) for patients with PE. Management for the four recommendations was conform for 5.6% of eligible patients in the "before" period and for 3.7% for the "after" period. CONCLUSION: Our study shows that globally there is no impact of RGP. The reasons appear multiple with first, the mere dissemination and the absence of implementation of these guidelines.
