    The Apgar score, a newborn evaluation method, is primarily used statistically. This study introduces a new index combining 1-minute and 5-minute Apgar scores for better outcome prediction.

    Area of Science:

    • Neonatal medicine
    • Pediatric assessment

    Background:

    • The Apgar score, developed 27 years ago, is a widely accepted method for newborn infant evaluation.
    • Initially a guide for resuscitation and statistical tool, its primary use is now statistical.
    • Current practice involves both 1-minute and 5-minute Apgar scoring, but consensus on which best indicates outcome is lacking.

    Purpose of the Study:

    • To address the cumbersomeness of using separate 1-minute and 5-minute Apgar scores.
    • To introduce a novel index that provides a single numerical value reflecting both scores and their relative change.
    • To analyze selected variables using this new index.

    Main Methods:

    • Development of a new index that integrates 1-minute and 5-minute Apgar scores.
    • Incorporation of the relative change between the two scores into the index.

  • Analysis of selected variables using the proposed index.

    • Main Results:

    • A new method is described for evaluating newborn infants using a single index.
    • This index accounts for both the 1-minute and 5-minute Apgar scores.
    • Analysis of selected variables using this index is presented.

    Conclusions:

    • The proposed index offers a more streamlined approach to newborn assessment compared to separate Apgar scores.
    • This single numerical value may provide a better indicator of infant outcome by considering both time points and change.
    • Further analysis using this index can aid in understanding neonatal well-being.
