Brief Summary:
Improving Telephone Triage in Emergency Calls with AI The Coordinating Centre for Urgencies and Emergencies in Andalusia (CCUE) handles thousands of calls every day. Each call needs to be assessed based on the information given over the phone to determine how serious the case is. The reasons for calling range from minor health issues to life-threatening emergencies like cardiac arrest (CPA).
This project focuses on improving telephone triage for four key emergency situations that often indicate severe or life-threatening conditions:
Unconsciousness / Cardiac arrest Difficulty breathing Chest pain (non-traumatic, possible heart-related issues) Stroke symptoms Our goal is to make telephone triage more accurate and efficient by using advanced Artificial Intelligence (AI) techniques, including Machine Learning (ML) and Natural Language Processing (NLP). These tools will help CCUE operators make better and faster decisions, ensuring that patients receive the right care as quickly as possible.
How it will be done:
The investigators will analyze anonymized historical call data from the emergency coordination system (CCR) and digital clinical records (HCDM). This includes:
Structured data: Predefined fields, such as answers to standard triage questions.
Unstructured data: Free-text notes and other information recorded during the call.
A hybrid AI approach will be used, combining:
Traditional AI methods (supervised learning and deep learning) to classify cases.
Generative AI techniques (advanced language models) to extract useful insights from free-text data.
Building the Best Prediction Model
To find the most effective AI model, we will test different machine learning techniques, including:
Decision Trees Random Forests Support Vector Machines (SVM) XGBoost Ensemble methods Neural Networks We will also analyze which questions and variables are the most important in predicting the severity of a case. Based on this, we will suggest improvements to the current triage questions to enhance accuracy.
Measuring Success
We will evaluate the AI model using key performance metrics, including:
Accuracy (overall correctness) Sensitivity (ability to detect real emergencies) Specificity (ability to avoid false alarms) False Positive \& False Negative Rates (how often the system makes mistakes) Likelihood Ratios (how well the system distinguishes between urgent and non-urgent cases) F1-Score \& ROC Curve (overall performance indicators) Why This Matters This project will assess how effective the current telephone triage system is and develop a new AI-powered model to improve it. The goal is to help emergency operators quickly identify the most serious cases, reducing response times and improving patient outcomes. In the future, the investigators aim to integrate this improved AI model into the CCUE system to enhance emergency response across Andalusia.

Detailed Description:
The Emergency and Urgent Care Coordination Center in Andalusia (CCUE) receives thousands of calls daily, during which each case must be classified by severity level based on the information provided over the phone. The conditions for which citizens seek help span a wide range-from minor ailments to cardiac arrest. This project addresses the challenge of telephone triage in out-of-hospital emergencies for several frequent reasons for care requests that may indicate emergent and potentially life-threatening medical conditions: unconsciousness/cardiac arrest, respiratory distress, non-traumatic chest pain, and stroke.
The goal is to improve the accuracy and efficiency of telephone triage using advanced Artificial Intelligence (AI) techniques-both symbolic and generative-including machine learning (ML) and natural language processing (NLP). This will enable CCUE CES-061 Andalucía operators to make faster, more informed decisions to provide timely and appropriate care.
The investigators will collect anonymized historical data from calls related to these four care request categories, extracted from the relational database systems of the Networked Coordination Centers (CCR) and the Mobile Digital Health Record (HCDM) of CES-061 Andalucía. The analysis will include both structured data (predefined fields with specific formats, including triage questions asked during the call) and unstructured data (free text and other formats) generated during demand management, encompassing coordination and care delivery aspects.
The investigators will implement a hybrid approach that integrates classical AI techniques (supervised and deep learning for classification) with generative AI (large language models to analyze and extract valuable insights from unstructured data). Various classification algorithms-such as decision trees, random forests, SVM, XGBoost, ensemble methods, and neural networks-will be tested to build the most accurate predictive model.
Through feature importance analysis, we will identify the most predictive questions and variables, proposing modifications to the current triage questions to enhance prediction accuracy.
The model will be evaluated using multiple metrics (including accuracy, sensitivity, specificity, positive and negative likelihood ratios, false positive rate \[alarm failure\], false negative rate \[omission failure\], area under the ROC curve, and F1-score). These metrics will help assess the model's ability to correctly predict final diagnoses-maximizing detection of truly urgent cases (high sensitivity, high positive likelihood ratio, and low false negative rate) while avoiding excessive false positives (high specificity, low false positive rate, and low negative likelihood ratio).
The aim of this project is to assess the effectiveness of the current CCUE telephone triage model and develop a new AI-based model to improve it. We aim to provide a solid foundation for future implementation of the improved model within CCUEs, helping personnel to quickly identify and prioritize the most severe cases, ultimately reducing response times and improving health outcomes.
