Definition and Clinical Significance

The Wells score is a clinical prediction rule for assessing the risk of pulmonary embolism (PE) in emergency department patients.

The score is calculated based on 11 clinical variables, including clinical signs, heart rate, respiratory rate, and more.

Wells Score Components

1
Clinical Signs — The presence of clinical signs such as pleuritic chest pain, cough, and hemoptysis
2
Heart Rate — An elevated heart rate, typically greater than 100 beats per minute
3
Respiratory Rate — An elevated respiratory rate, typically greater than 20 breaths per minute
4
Oxygen Saturation — A decreased oxygen saturation, typically less than 90%
5
Alternative Diagnosis — The presence of an alternative diagnosis that could explain the patient's symptoms
6
Heart Rate — An elevated heart rate, typically greater than 100 beats per minute
7
Respiratory Rate — An elevated respiratory rate, typically greater than 20 breaths per minute
8
Hemoptysis — The presence of hemoptysis, which is a significant risk factor for PE
