Treatment of submassive and massive pulmonary embolism: a clinical practice survey from the second annual meeting of the Pulmonary Embolism Response Team Consortium.

There is a paucity of robust clinical trial data to guide the treatment of acute pulmonary embolism (PE) thus the clinical guidelines rely heavily on expert opinion. Pulmonary Embolism Response Teams (PERT) have been developed to streamline the care of patients with acute PE. We conducted a survey among 100 experts in the field of PE during the second annual meeting of the PERT Consortium. Respondents were queried with respect to their demographic information, clinical practice questions and clinical vignettes. Clinical practice questions were focused questions about the risk stratification and treatment of patients with acute submassive PE, anticoagulation strategies for patients receiving thrombolysis and the use of inferior vena cava filters. Clinical vignettes were designed to assess participants' preferred choice of treatment for a variety of commonly encountered clinical scenarios. Among physicians affiliated with a PERT, there is overall agreement with regards to the criteria used for risk classification of patients with PE and its application to patients in the provided clinical vignettes. In contrast, there is substantial variability in the treatment strategies of patients presenting with commonly encountered clinical scenarios. The results of this survey highlight the need for more clinical trial data along with accepted algorithms for treatment of acute PE. In the absence of this, PERTs can facilitate multidisciplinary discussions in order to standardize treatment and provide evidence-based therapies to patients with acute PE.
