    Pediatric Asthma Severity Score (PASS) for Asthma Exacerbation Severity

    Determines pediatric asthma severity based on physical exam findings.


    Applicable to pediatric patients 1-18 years of age.
    When to Use
    Why Use

    Pediatric patients (1-18 years old) with asthma exacerbations.

    • The Pediatric Asthma Severity Score (PASS) provides a method for predicting likelihood of admission or extended ED stay.
    • The PASS uses variables such as work of breathing (commonly used in decision to admit), and thus it may over-estimate score's utility.

    This score can help decide which patients need admission, especially when providers disagree or the patient may be “borderline” for needing admission.

    The PASS score works best when done initially and after treatment to show a trend, but this may be the same as clinician reassessment as well.
