Venous Thromboembolic Disease [VTED: 
Algorithms to aid in Diagnosis and Risk Stratification

Introduction

The diagnosis of VTED can be challenging and various clinical prediction rules have been developed in order to improve diagnosis and decision making.

The commonly used algorithms are summarised below with links to the specific algorithms.  For additional information of other algorithms - see References.



The Wells DVT Score


The Wells DVT score is used to evaluate a patient with a suspected DVT to establish the probability that this is is likely or unlikely.  The Wells DVT score is frequently then combined with D-dimer testing to guide further investigation/management.

The Wells PE Score


The Wells PE score is used to evaluate a patient with a suspected PE to establish the probability that this is is likely or unlikely.  The results of the Wells score will guide additional investigations and management.

The Revised GENEVA PE Score


The Revised GENEVA score is a clinical prediction rule used to determine the pre-test probability of Pulmonary Embolism [PE] based on a patient's risk factors and clinical findings.

Other RISK Prediction Scores


A number of other prediction scores have been developed to investigate a patient with a suspected VTED.  These include:

  The Hamilton Score
   The Oudega Score
   The Kahn Score
   The Constans Score
   The St Andre Score
   The Gagne Score

and in pregnancy The LEFT Score.
