Method · Limits of application

Westley 1978: 5 factors, 0–17; croup

The Westley 1978 publication assessed 20 children aged 4 months to 5 years, hospitalized for acute croup with persistent stridor at rest, in an intervention trial. That range describes the original cohort and does not by itself determine universal limits for use of the score. The adopted scoring table and severity classification require specific checking.

Conditions of use

Check the population, units, inclusion and exclusion criteria, and version in the original source. A result alone does not establish a diagnosis, discharge decision or prescription.
