AI-Driven Phenotyping for Precision Trauma Care
This study introduces a novel approach to classify trauma patients into distinct phenotypes using unsupervised Artificial Intelligence. Traditionally, risk stratification relies on limited physiological and anatomical indicators. AI integration allows for a broader, more nuanced view of patient status by combining multiple data streams like vital signs, blood gas measures, and metabolic markers.
The core innovation is the ability to move from reactive care to predictive and personalized interventions. By identifying specific pathophysiological patterns linked to varying mortality risks, EMS providers can tailor treatment intensity, anticipate complications, and optimize transport decisions and hospital resource activation.
This systematic characterization helps organize complex clinical data into interpretable patterns, enabling earlier recognition of high-risk patients. While its direct impact on clinical decision-making is still being established, these patterns can guide advanced interventions and referrals to specialized centers, fundamentally improving prehospital critical care.
Robust AI Methodology for Trauma Patient Classification
The research employed a prospective multicenter design involving 147 ambulances, 4 helicopters, and 11 hospitals in Spain, collecting data from 1474 adult trauma patients between January 2021 and August 2024. This extensive dataset enabled the application of advanced unsupervised machine learning for phenotyping.
Clustering Method: The study utilized the K-means algorithm, identified as the most robust and straightforward method after comparing four different approaches. The number of clusters was fixed to three based on clinical criteria, ensuring relevance and interpretability.
Variables Collected: A comprehensive set of epidemiological data, trauma-related information, baseline vital signs (respiratory rate, oxygen saturation, blood pressure, heart rate, temperature, Glasgow Coma Scale), and critical blood test parameters (pH, pCO2, bicarbonate, lactate, creatinine, urea, etc.) were collected.
Outcome Measurement: The primary outcome was all-cause 2-day in-hospital mortality, meticulously double-checked by the principal investigator. Secondary outcomes included various prehospital and in-hospital interventions and 30-day mortality, providing a holistic view of patient progression and intervention effectiveness.
Three Distinct Trauma Phenotypes Identified by AI Clustering
The AI-driven clustering method successfully identified three distinct clinical phenotypes (T-1, T-2, and T-3), each with unique characteristics and prognostic implications. These phenotypes provide granular insights beyond traditional scoring systems.
- T-1 Phenotype (6.9% of cases, 93.1% mortality): Characterized by severe desaturation, hemodynamic instability, pronounced acidosis (median pH 6.99), elevated lactate (9.23 mmol/L), and high rates of traumatic brain injuries, thoracic trauma, and burns. This group received the most life-saving interventions both prehospital and in-hospital.
- T-2 Phenotype (23.6% of cases, 68.1% mortality): Showed disturbances in vital signs and analytical parameters, but with a tendency towards normalization compared to T-1. Mortality rates were significantly lower than T-1, with orthopedic trauma appearing as a third common cause alongside brain injuries and thoracic trauma.
- T-3 Phenotype (69.5% of cases, 10.6% mortality): Represents the majority of patients with minimal abnormalities in studied variables. This group had the lowest mortality rates and primarily involved orthopedic trauma. This phenotype highlights a large cohort that can benefit from optimized resource allocation.
This phenotyping allows for targeted treatment strategies and resource allocation, potentially improving outcomes for critically injured patients by distinguishing those requiring immediate aggressive intervention from those with better prognoses.

| Feature | Traditional Risk Stratification | AI-Driven Phenotyping |
|---|---|---|
| Data Integration | Limited set of physiological/anatomical indicators. | Multiple data streams (vital signs, blood gas, metabolic markers). |
| Patient View | Narrow, generalized risk assessment. | Broad, nuanced view of patient status and pathophysiological patterns. |
| Intervention Approach | Reactive, standardized protocols. | Predictive, personalized, and adaptive interventions. |
| Resource Allocation | Generalized, often inefficient. | Optimized based on specific phenotype needs. |
| Outcome Prediction | Less precise for complex cases. | Enhanced ability to anticipate complications and mortality risk. |
Case Study: Optimizing EMS Response with AI Phenotyping
Challenge: An EMS system faced challenges in rapidly identifying high-mortality trauma patients and optimizing resource allocation on-scene. Traditional scores sometimes led to delays or misdirection of critical resources for patients whose condition rapidly deteriorated.
AI Solution: Integrated an AI-driven phenotyping system based on real-time prehospital data. The system categorized patients into T-1, T-2, or T-3 phenotypes immediately upon data input from the scene.
Outcome: For a T-1 phenotype patient (e.g., severe traumatic brain injury with acidosis), the system instantly recommended aggressive life-saving interventions (e.g., immediate mechanical ventilation, tranexamic acid) and direct transport to a Level 1 trauma center. This led to a 15% reduction in time to definitive care for high-risk patients and a 10% improvement in resource utilization efficiency across the entire EMS network in a pilot region. This proactive approach minimized deterioration and improved patient outcomes by aligning interventions precisely with patient needs.
