The modified respiratory index score (RIS) guides resource allocation in acute bronchiolitis

Area of Science:

• Pediatric Pulmonology
• Respiratory Medicine
• Clinical Pediatrics

Background:

• Bronchiolitis is a frequent childhood illness with rising healthcare demands.
• Accurate prediction of hospitalization is crucial for resource management.

Purpose of the Study:

• To evaluate the efficacy of a modified Respiratory Index Score (RIS) in predicting hospital admission for bronchiolitis.
• To assess the modified RIS's performance in identifying infants requiring significant medical intervention.

Main Methods:

• An observational prospective study was conducted in a pediatric emergency department.
• Included were children under 2 years with bronchiolitis, excluding those with specific risk factors.
• A warranted admission was defined by the need for airway intervention, IV hydration, or hospitalization of ≥2 days.

Main Results:

• A modified RIS score greater than 4 significantly predicted warranted admissions (aOR: 3.28).
• This predictive association remained robust even in children experiencing their first wheezing episode.
• The study analyzed 1,818 patients, with 1.0% requiring respiratory support and 5.6% needing IV hydration.

Conclusions:

• The modified RIS is a valuable, simple tool for predicting the need for respiratory support, IV hydration, and extended hospital stays in infants with bronchiolitis.
• This score aids in clinical decision-making for managing pediatric respiratory illnesses.
