Pulmonary Embolism Probability Scoring

The Wells score is used to determine the probability of a pulmonary embolism based on a person's history and examination. There is additionally a Wells score for deep vein thrombosis.

Criteria	Points	Points (simplified)	Present
Symptoms or signs of deep vein thrombosis	3	1	<html><input class="wells-item" type="checkbox" value="30" onclick="window.wellsScore(this);" /></html>
Autres diagnostics moins probables	3	1	<html><input class="wells-item" type="checkbox" value="30" onclick="window.wellsScore(this);" /></html>
FC > 100/min	1.5	1	<html><input class="wells-item" type="checkbox" value="15" onclick="window.wellsScore(this);" /></html>
Immobilisation (≥ 3 jours) ou chirurgie récente (< 4 semaines)	1.5	1	<html><input class="wells-item" type="checkbox" value="15" onclick="window.wellsScore(this);" /></html>
Antécédents de thrombose veineuse profonde ou d'embolie pulmonaire	1.5	1	<html><input class="wells-item" type="checkbox" value="15" onclick="window.wellsScore(this);" /></html>
Hémoptysies	1	1	<html><input class="wells-item" type="checkbox" value="10" onclick="window.wellsScore(this);" /></html>
Cancer	1	1	<html><input class="wells-item" type="checkbox" value="10" onclick="window.wellsScore(this);" /></html>
Probability	Faible
Probability (simplified)	Peu probable

Original version: low (0-1), intermediate (2-6), high (>6)^{[note 1]}
Simplified: low probability (0-1), higher probability (>1)^{[note 2]}

 $(element).closest("table").find("input[type=checkbox]").filter(":checked").each(function(){
  score += parseInt($(this).attr("value").replace(",", "."));
 });
 
 score /= 10; // parseFloat is not defined in chrome !!!!!????

Notes[edit | edit source]

↑ Pour le risque faible, on estime la probabilité à moins de 19%, pour le risque intermédiaire, il est entre 10% et 79% et pour le risque élevé, il est supérieur à 80%.
↑ 12% des cas d'EP seront décrits comme peu probables.
