Synonyms and Keywords: BSS
The bronchiolitis severity score (BSS) is an assessment scale used to evaluate the severity of illness in infants.
Data Source for Derivation and Validation
The BSS was tested for reliability by two of the original investigators. The investigators reported kappa of the individual components of the score:
- General assessment: Kappa was 0.48
- Respiratory rate: Kappa was 0.38
- Wheezing: Kappa was 0.31
- Retractions: Kappa was 0.25
Alternative severity scales include:
- Court's scale: This scale includes respiratory rate and assessments of retractions, adventitial sounds, skin color, and general condition.
- Respiratory distress observation scale (RDOS): This scale includes the scores of four findings on a scale ranging from 0 to 3 so that total scores range from 0 to 12.
- Tal and modified-Tal scoring systems
|Score||Respiratory Rate||Wheezing||Retraction||General Condition|
|1||30–45||Terminal expiration or only with stethoscope||Intercostal|
|2||46–60||Entire expiration or audible on expiration without stethoscope||Tracheosternal|
|3||>60||Inspiration and expiration without stethoscope||Irritability, lethargy, poor feeding|
