Venous Thromboembolism (VTE)

When a blood clot breaks loose and travels in the blood, this is called a venous thromboembolism (VTE). The abbreviation DVT/PE refers to a VTE where a deep vein thrombosis (DVT) has moved to the lungs (PE or pulmonary embolism).

In VTE risk assessment, there are three options for recording this information on the drop down menu: Yes / No / N/A. If the patient has a documented risk assessment for VTE then select, ‘Yes’ if not, select ‘No’. Alternatively, if the question is not appropriate for the patient or setting select ‘N/A’.

This data enables the calculation of the following indicator:

  • V1:
    • The proportion of patients with a documented VTE risk assessment.

 

VTE prophylaxis

The Safety Thermometer asks you to record whether or not an ‘at risk’ patient has started appropriate VTE prophylaxis. This information is required for all surveyed patients. There are three options for recording this information on the drop down menu: ‘Yes’, ‘No’ and ‘N/A’.

If the patient has started appropriate VTE prophylaxis then select, ‘Yes’, if not, select ‘No’. If the question is not appropriate for the patient or setting, for example they are not ‘at risk’ or are contraindicated for prophylactic treatment then select ‘N/A’. This data enables the calculation of the

following indicator:

  • V2:
    • The proportion of ‘at risk’ patients receiving appropriate prophylaxis (in accordance with local guidance).

 

New VTE

The NHS Safety Thermometer asks you to record whether or not a patient is being clinically treated for VTE of any type. A patient may be defined as having a new VTE if they are being treated for a deep vein thrombosis (DVT), pulmonary embolism (PE) or any other recognised type of VTE with appropriate therapy such as anticoagulants. Old VTEs are not counted in this measure. To collect the data, you may wish to assess or ask the patient about any VTE symptoms or treatment as well as consulting their notes or handover documents. If treatment for a VTE was started after the patient was admitted to your organisation, select one of the ‘new’ categories from the drop down menu; this will be one of ‘new DVT’, ‘new PE’ or ‘new other’.

If treatment for the VTE started before the patient was admitted to your organisation, use the ‘old’ categories from the drop down menu; this will be one of ‘old DVT’, ‘old PE’ or ‘old other’. If the patient is not being treated for a VTE, select ‘No VTE’. This data enables the calculation of the following indicator:

  • V3:
    • The proportion of patients receiving anticoagulation treatment (heparin, warfarin or equivalent) for treatment of a NEW clinically documented VTE event. This measure can be viewed by category (DVT/PE/Other). The measure can also be viewed by OLD and NEW VTE.
