Summary

A new decision tree algorithm accurately predicts which infants with neonatal brachial plexus palsy (NBPP) may benefit from surgery. This tool uses maternal and neonatal factors to identify early surgical candidates, improving arm function outcomes.

Area of Science:

  • Pediatric Surgery
  • Neurology
  • Medical Informatics

Background:

  • Neonatal brachial plexus palsy (NBPP) significantly impairs arm function and quality of life.
  • Surgical interventions can improve outcomes for selected NBPP patients, but patient selection is challenging.

Purpose of the Study:

  • To develop a predictive decision algorithm for identifying infants with NBPP who would benefit from early surgical intervention.
  • The algorithm aims to reliably predict persistent NBPP requiring surgery at an individual patient level.

Main Methods:

  • A retrospective review of NBPP patients was conducted.
  • Maternal and neonatal factors were analyzed using a C5.0 decision tree model in R.
  • A 60/40 data split was used for training and testing the predictive model.

Main Results:

  • A decision tree algorithm was generated using variables such as Horner's syndrome, pseudomeningocele, Narakas grade, clavicle fracture, birth weight, and labor induction/augmentation.
  • The algorithm demonstrated high specificity (0.96) and positive predictive value (0.94) for identifying surgical candidates.
  • Sensitivity was 0.71, negative predictive value was 0.79, and F1 score was 0.81.

Conclusions:

  • A novel decision tree algorithm, utilizing only maternal and neonatal factors, can predict surgical candidacy in NBPP patients shortly after birth.
  • This algorithm represents a significant advancement in early identification of infants who may benefit from surgical intervention for NBPP.
