Patient Triage System
Rules-based medical triage system that prioritizes patients in emergency departments based on vital signs, symptoms, and chief complaints.
Solution
This triage system quickly identifies the appropriate care priority for patients in emergency departments. Using medical best practices, it evaluates vital signs including temperature, heart rate, respiratory rate, blood pressure, and oxygen saturation. The system analyzes reported symptoms, assigning higher scores for severe conditions like chest pain or difficulty breathing, while giving lower scores to mild symptoms like coughs or minor injuries.
Chief complaints are categorized by severity, with life-threatening conditions like stroke or cardiac arrest receiving immediate attention. The system calculates a comprehensive priority score by combining vital signs, symptoms, and complaint assessments. Each patient is then assigned a specific priority level from 1 (Immediate) to 5 (Non-Urgent), with recommended maximum wait times ranging from immediate treatment to 120 minutes based on medical urgency.
How it works
The decision graph evaluates patients through four distinct assessment phases:
Vital Signs Assessment: Analyzes key physiological indicators including temperature, heart rate, respiratory rate, blood pressure, and oxygen saturation, assigning scores and flags based on deviation from normal ranges.
Symptom Evaluation: Reviews reported symptoms, categorizing them into severity levels from severe (red flag) to minor (green flag) with corresponding scores.
Chief Complaint Analysis: Assesses the patient's primary complaint, with life-threatening conditions receiving highest priority scores.
Priority Calculation: Combines all assessment scores and flags to determine final priority level (1-5), establishing maximum wait times and identifying the highest risk factors.
