Diagnosis and management of venous thromboembolism: Results of a survey on current clinical practice

Background: The implementation of evidence from clinical studies into daily clinical practice is not a straightforward process. We developed a standardized questionnaire to explore clinical practice patterns in the management of VTE, in particular about the use of pre-clinical probability and D-dimer testing and on the home treatment of pulmonary embolism (PE). Methods: The standardized questionnaire was sent to all 394 physician members of the Italian Society of Thrombosis and Haemostasis (SISET) by e-mail. The questionnaire contained three groups of questions: about general information, about the diagnostic process for both deep venous thrombosis (DVT) and PE, and about home-therapy of PE. Results: One hundred and twenty-eight (32.5%) physicians responded the questionnaire. For DVT diagnosis 69 (54.3%) physicians answered that they always use the D-dimer test; 4 (3.1%) do never use it; whereas only 11 (8.7%) take notice of the D-dimer result before visiting the patients; 38 (29.9%) use only clinical judgment to assess pre-clinical probability of disease. For the diagnosis of PE 80 (66.1%) physicians always use the D-dimer test, whereas 3 (2.5%) do never use it; whereas 14 (11.7%) take notice of the D-dimer result before visiting the patients; 50 (41.3%) use only clinical judgment to assess pre-clinical probability. Sixty-six (59.5%) clinicians declared to treat patients with PE at home, when feasible. Conclusion: The diagnostic approach to VTE among expert physicians appears to be heterogeneous; in particular there is no widespread use of clinical prediction rules. The majority of expert physicians appear to consider the possibility of treating at home patients with PE. © 2009 Elsevier Ltd. All rights reserved.
