This one-page snapshot provides a high-level summary of the guidelines on the types of interventions that should be used to prevent VTE in hospitalized and non-hospitalized medical patients. A snapshot of the full VTE guidelines is also available for download.
For patients with uncomplicated deep vein thrombosis (DVT), the American Society of Hematology (ASH) guideline panel suggests offering home treatment over hospital treatment (conditional recommendation based on low certainty in the evidence of effects ⨁⨁ ).
The most likely source of thrombus in pulmonary arteries is an embolization from deep veins in the legs. This activity reviews the causes of DVT and highlights the role of the interprofessional team in the prophylaxis against DVT. Objectives: Identify the cause of DVT.
In acutely or critically ill medical patients who do not receive pharmacological VTE prophylaxis, the ASH guideline panel suggests using mechanical VTE prophylaxis over no VTE prophylaxis (conditional recommendation, moderate certainty in the evidence of effects ⊕⊕⊕ ).
For major general surgery, the panel suggested pharmacological prophylaxis over no prophylaxis, using LMWH or unfractionated heparin. For major neurosurgery, transurethral resection of the prostate, or radical prostatectomy, the panel suggested against pharmacological prophylaxis.
The ASH guidelines define the treatment period of acute DVT/PE as “initial management” (first 5-21 days), “primary treatment” (first 3-6 months), and “secondary prevention” (beyond the first 3-6 months). The guidelines favor shorter courses of anticoagulation (3-6 months) for acute DVT/PE associated with a transient risk factor.
The American Society of Hematology (ASH) has long recognized the need for a comprehensive set of guidelines for hematologists and other clinicians on venous thromboembolism (VTE), a common and serious blood clotting condition that includes both deep-vein thrombosis (DVT) and pulmonary embolism (PE).
Most hospital-related VTE events occur out of hospital, in the first month after discharge. VTE risk in medical patients is elevated for 45-60 days post-discharge. Duration of inpatient prophylaxis is shortening as the average hospital length of stay decreases.
The American Society of Hematology has updated recommendations for management of VTE, which includes deep venous thrombosis (DVT) and pulmonary embolism (PE).
The guideline panel rated mortality, PE, deep venous thrombosis (DVT), and major bleeding as critical for decision making and placed a high value on these outcomes and avoiding them with the interventions that were evaluated.
