Overview
VTE Prevention in Non Surgical Patients
Hospitalized Acutely Ill Medical Patients
Shown below is the indications and choices of VTE prophylaxis among acutely ill patients. If VTE prophylaxis is recommended, it should be administered for the period of immobilization or hospital stay. Do not extend the duration of the prophylaxis after the period of immobilization or hospital stay.[1]
| What is the risk of thrombosis in the acutely ill patient? | |||||||||||||||||||||||
| High | Low | ||||||||||||||||||||||
| Is the patient bleeding or at high risk of bleeding? | No VTE prophylaxis | ||||||||||||||||||||||
| Yes | No | ||||||||||||||||||||||
| Mechanical VTE prophylaxis For the period of immobilization or hospital stay only Graduated compression stocking Intermittent pneumatic compression | Pharmacological VTE prophylaxis For the period of immobilization or hospital stay only LMWH Low dose UFH, BID Low dose UFH, TID Fondaparinux | ||||||||||||||||||||||
| Did the bleeding or bleeding risk subside AND the patient is still at increased risk of thrombosis? | |||||||||||||||||||||||
| Yes | No | ||||||||||||||||||||||
| Substitute mechanical prophylaxis by pharmacological prophylaxis | Continue mechanical prophylaxis | ||||||||||||||||||||||
Assessment of Risk of VTE in Hospitalized Patients
Critically Ill Hospitalized Patients
Shown below is an algorithm depicting the choices for VTE prophylaxis among critically ill patients. Note that routine ultrasound screening for DVT is not recommended among critically ill patients. Do not extend the duration of the prophylaxis after the period of immobilization or hospital stay.[1]
| Is the critically ill patient bleeding or at risk for major bleeding? | |||||||||||||||||
| Yes | No | ||||||||||||||||
| Mechanical VTE prophylaxis Graduated compression stocking Intermittent pneumatic compression | Pharmacological VTE prophylaxis LMWH Low dose UFH | ||||||||||||||||
| Did the bleeding or bleeding risk subside? | |||||||||||||||||
| Yes | No | ||||||||||||||||
| Substitute mechanical prophylaxis by pharmacological prophylaxis | Continue mechanical prophylaxis | ||||||||||||||||
Cancer in Outpatient
Shown below is an algorithm depicting VTE prophylaxis among cancer patients. Note that, cancer patients with indwelling central venous catheters do not require VTE prophylaxis with neither LMWH, low dose unfractionated heparin or vitamin K antagonists.[1]
| ❑ Does the patient have a solid tumor AND ❑ Additional risk factors for VTE?
| |||||||||||||||
| Yes | No | ||||||||||||||
| Pharmacological VTE prophylaxis LMWH Low dose UFH | No VTE prophylaxis | ||||||||||||||
Chronically Immobilized Patients
No VTE prophylaxis is recommended in subjects who are chronically immobilized either at home or at a nursing home.[1]
Long Travel
| Does the patient has any of the following that increase the risk of VTE? Prior VTE episode Recent trauma Recent surgery Active cancer Advanced age Immobility Severe obesity Estrogen intake Thrombophilia | |||||||||||||||||
| Yes | No | ||||||||||||||||
| Frequent ambulation Calf muscle exercise To sit in an aisle seat Graduated compression stockings below the knee (pressure: 15-30 mmHg) No pharmacological VTE prophylaxis | No preventive measures are required | ||||||||||||||||
Asymptomatic Thrombophilia
VTE prophylaxis is not recommended for subjects with asymptomatic thrombophilia. [1]
