Statechart Models for Neonatal Adaptation

Formal statechart modeling of neonatal adaptation guidelines for medical education, clinical representation and simulation.

Overview

This project focuses on the formal representation of immediate neonatal adaptation guidelines using statechart models.

The work was motivated by the need to improve the clarity, structure and pedagogical usability of complex clinical protocols related to neonatal transition and physiologically based umbilical cord clamping.

The project transforms clinical guidelines into a formal discrete-event representation that can be understood by medical professionals, engineers and students.

Scientific Context

Immediate neonatal adaptation involves a sequence of clinical decisions based on the physiological condition of the newborn.

Traditional clinical flowcharts are useful for communication, but they may become limited when protocols include multiple patient states, transitions, clinical indicators and nested decision structures.

Statecharts provide a formal graphical language capable of representing:

  • States
  • Events
  • Transitions
  • Superstates
  • Decision logic
  • Clinical evolution

This makes them suitable for representing complex medical guidelines in a structured and reusable way.

Main Objectives

The project pursues the following objectives:

  • Represent neonatal adaptation guidelines using statecharts.
  • Improve the clarity of clinical decision pathways.
  • Formalize physiological criteria for neonatal transition.
  • Support simulation-based medical education.
  • Facilitate interdisciplinary communication between engineers and clinicians.
  • Explore the use of discrete-event systems in medical protocol representation.

Methodology

The methodology consists of transforming clinical guidelines into a formal statechart model through progressive refinement and interdisciplinary validation.

Formal statechart representation of immediate neonatal adaptation guidelines, including patient states, clinical events and decision transitions.

Axis 1 – Clinical Guideline Analysis

The first step consists of analyzing the medical guideline and identifying:

  • Patient states
  • Clinical indicators
  • Decision criteria
  • Intervention sequences
  • Transition conditions

Axis 2 – Statechart Modeling

The clinical procedure is then represented using statecharts.

The model includes:

  • States
  • Events
  • Transitions
  • Superstates
  • Clinical decision logic
  • Physiological evolution conditions

Axis 3 – Interdisciplinary Evaluation

The model is evaluated by an interdisciplinary panel including engineers and health professionals.

The evaluation focuses on:

  • Usability
  • Visual clarity
  • Scalability
  • Interpretability
  • Educational potential

Main Contributions

The project contributes to:

  • Formal representation of medical guidelines.
  • Application of discrete-event systems to neonatology.
  • Improved visualization of neonatal adaptation protocols.
  • Human-centered representation of clinical procedures.
  • Support for medical education and training.

Scientific Impact

This project demonstrates that statechart models can be used as a formal and pedagogical tool for representing complex medical guidelines.

The approach opens new perspectives for the integration of systems engineering, knowledge representation and clinical education.
