A survey of physicians' opinions about the treatment of subsegmental pulmonary embolism.

INTRODUCTION

The aim of this study was to survey the attitudes of internists, cardiologists, and pulmonologists regarding treatment or no treatment of isolated subsegmental pulmonary embolism (ISSPE) with anticoagulant drugs.

METHODS

Qualified physicians were asked to select their management options from a questionnaire that included a patient scenario with subsegmental pulmonary embolism (SSPE) and negative past medical history of thromboembolism.

RESULTS

A total of 113 physicians responded to the survey. Of these, 8.8% preferred not to treat patients without further evaluation; 15% decided not to treat, but follow-up the patient with a serial lower-limb colour Doppler ultrasonography; 1.7% preferred anticoagulant treatment only during hospitalization and follow-up without medication; 5% preferred anticoagulant treatment for less than 3 months; and 34.5% chose a 3-6-month treatment with anticoagulation. Furthermore, 24% of physicians opted for anticoagulant treatment for more than 6 months, and 9.7% left the decision up to the patient. Opting not to treat was an option selected by more board-certified faculty members specialized in cardiology, internal medicine, and pulmonology compared with residents ( = 0.038). Willingness to provide anticoagulant therapy in the internal medicine, cardiology and pulmonology groups was 56.6%, 37.3% and 6%, respectively ( = 0.007).

CONCLUSION

The majority of physicians surveyed prefer anticoagulant therapy in patients with SSPE.
