CHINDAMO, Maria Chiara  and  MARQUES, Marcos Arêas. Role of ambulation to prevent venous thromboembolism in medical patients: where do we stand?. J. vasc. bras. [online]. 2019, vol.18, e20180107.  Epub July 04, 2019. ISSN 1677-5449.

Venous thromboembolism (VTE) encompasses the spectrum of manifestations of deep venous thrombosis and/or pulmonary embolism and is a common, serious, and preventable complication in hospitalized patients. Although immobility plays an important role in determining VTE risk in medical patients, no clear and uniform criteria exist to guide clinicians in assessing immobility. The variation in the descriptions that do exist makes it difficult to interpret and compare the results of randomized clinical trials with respect to the influence of different levels of immobility on the magnitude of VTE risk and the role that early ambulation as an isolated factor plays in prevention of such events. Understanding these limitations is a prerequisite for the proper use and interpretation of VTE risk assessment tools and for indicating the best strategy for preventing venous thrombosis in hospitalized medical patients. The objective of this study was to review the main evidence reported in the literature on the role of ambulation in prevention of VTE.

Keywords : deep venous thrombosis; pulmonary embolism; thromboprophylaxis; patient safety; mobility limitation.
