    Predicting pediatric asthma emergency visits is possible using temperature change. This model, focusing on temperature velocity, explains significant daily and weekly variations, aiding in emergency department planning and potential prevention strategies.

    Area of Science:

    • Environmental Health
    • Pediatric Pulmonology
    • Biostatistics

    Background:

    • Pediatric asthma exacerbations frequently lead to emergency department visits.
    • Predictive models for asthma-related emergency visits are crucial for resource allocation and patient management.

    Purpose of the Study:

    • To develop and validate a predictive model for pediatric asthmatic wheezing emergency department visits.
    • To investigate the role of temperature change, specifically temperature velocity, as a predictor.

    Main Methods:

    • Analysis of 9,425 pediatric asthma emergency visits from 1982-1983.
    • Construction of a statistical model using temperature velocity and seasonal temperature change.
    • Evaluation of other environmental factors like CO, barometric pressure, and humidity.

    Main Results:

    • The model significantly predicted daily (R2=35%) and weekly (R2=49%) variations in asthma emergency visits.
    • Temperature velocity was a highly significant predictor (P<0.0001).
    • Other factors like CO, pressure, and humidity showed statistical significance but limited clinical impact.

    Conclusions:

    • Temperature velocity is a powerful predictor of pediatric asthma emergency visits.
    • Improved predictive models can aid in emergency department staffing and proactive patient care.
    • Utilizing seasonal patterns and temperature changes can enhance asthma management strategies.
