Advancements in Triage Systems: How AI Transformations Are Shaping Emergency Medicine Practices

Triage is an essential step in emergency care where clinical staff evaluate patients as they arrive and assign urgency levels. This assessment guides the order of treatment and resource allocation. Traditionally, triage nurses use a scale from one (most critical) to five (least critical), based on symptoms, vital signs, and medical history. However, this process can be subjective and may differ between nurses assessing the same patient. Such differences can cause inconsistencies in care, inefficiencies, and delays for patients needing urgent attention.

Healthcare leaders in the United States aim to address these issues not only to improve patient flow but also to optimize resource use, reduce waiting times, and lower the risk of negative outcomes in busy settings. Because of these needs, AI-driven solutions have become an important part of efforts to enhance triage accuracy and operational performance.

AI-Driven Triage Assistance: The Development of TriageGO

One example of AI applied to triage comes from Johns Hopkins University researchers who created an AI tool named TriageGO. This tool helps emergency nurses assign triage levels more objectively by using data from patients’ digital health records, including medical history and vital signs in real time.

TriageGO uses complex algorithms to analyze this data and predicts the risk of certain acute outcomes. It then recommends an appropriate triage level based on these predictions, capturing details that might be overlooked in manual assessments. Its ability to process large amounts of information quickly allows nurses to make better-informed decisions, especially when time is limited in busy emergency departments.

The tool is currently in use at The Johns Hopkins Hospital, Johns Hopkins Bayview Medical Center, Howard County General Hospital, and has expanded to hospitals in Florida, Connecticut, and Missouri. After being developed by Stocastic, a company co-founded by Scott Levin and Eric Hamrock, TriageGO was acquired by Beckman Coulter, a company specializing in clinical diagnostics, showing recognition of AI’s usefulness in emergency medicine.

Scott Levin, an associate professor of emergency medicine and one of TriageGO’s developers, noted: “What we’ve done is help the nurses confidently identify a larger group of those low-risk patients. When you do that, those people go on more efficient patient care pathways and get out of the ED sooner, creating improved patient flow.”

Improving Emergency Department Operations Through AI

The impact of AI in triage reaches beyond just assigning categories. The use of AI triage tools leads to:

• Enhanced Patient Flow: The AI can better identify low-risk patients, reducing unnecessary evaluations and admissions. This helps free up beds and decreases crowding.
• Standardized Decision-making: By applying consistent criteria, AI reduces differences between nurses’ assessments, resulting in more reliable triage decisions.
• Faster Time to Intervention: Promptly recognizing patients in critical condition ensures they get immediate care while lower-risk patients are directed appropriately.
• Clinical Confidence: AI support gives nurses added confidence in their decisions, aiding morale and reducing mental strain during busy periods.

From an administrative view, these improvements are significant. Quicker patient flow lowers cost per visit and enables hospitals to treat more patients without sacrificing quality. For IT managers, connecting AI tools with existing electronic health records simplifies workflows and supports decisions based on data.

Broader AI Applications in Emergency Medicine

AI’s influence in emergency care extends beyond triage. Sara Murray, MD, MAS, Vice President and Chief Health AI Officer at UCSF Health, points out that AI tools address various operational and clinical challenges. Automated clinical documentation through AI scribes reduces paperwork for clinicians, allowing more focus on patient interaction.

Dr. Murray explained, “AI scribes will revolutionize patient-physician interactions by eliminating the need for doctors to type during visits.” This speeds up data entry and cuts errors, both critical in time-sensitive emergency settings.

Additionally, AI helps improve diagnostic accuracy by providing data-informed differential diagnoses, combining complex patient data, and predicting acute deteriorations. In fast-paced emergency rooms, AI acts as a decision support aid, adding objectivity and lowering diagnostic mistakes.

In alert management, AI systems filter large numbers of patient alerts and prioritize those needing urgent attention. This helps reduce alert fatigue, which can lead to oversight and clinician burnout.

However, Dr. Murray stresses that healthcare providers must carefully review AI outputs to avoid automatic reliance. AI is meant to assist clinical judgment, not replace it.

AI and Workflow Automation: Enhancing Emergency Department Efficiency

AI integration in emergency medicine also includes automating workflows. Emergency departments must manage many tasks simultaneously such as patient intake, data entry, team communication, and paperwork. AI-based automation tools improve these by:

• Automated Call and Appointment Handling: Companies like Simbo AI use AI-powered phone systems to answer calls, schedule appointments, ask basic triage questions, and direct patients without overwhelming front desk staff. This reduces call wait times and improves patient experience.
• Seamless Integration with EHRs: Automated tools connect with electronic health records to ensure patient data collected through phone triage, kiosks, or tablets is promptly and accurately added to records. This lowers transcription mistakes and duplicate entries.
• Task Prioritization and Communication: AI tools flag urgent cases and incomplete documents, sending reminders to nurses and doctors. This ensures timely patient care and that critical steps aren’t missed.
• Operational Analytics: AI analyzes workflow, patient numbers, and resource use to identify slow points. This data helps administrators plan staffing, allocate resources, and set policies to improve efficiency.
• Predictive Staffing Models: Some AI systems forecast patient volumes and staffing needs based on past trends and current conditions. This helps hospitals schedule staff better to avoid shortages or excess.

For hospital IT teams, deploying these AI tools means working closely with clinical, administration, and technical teams to maintain regulatory compliance such as HIPAA, protect against cyber threats, and ensure the systems are user-friendly.

Addressing Ethical and Practical Considerations in AI Deployment

Despite its benefits, AI raises important ethical and practical issues that U.S. healthcare leaders must manage:

• Data Privacy and Security: AI processes sensitive patient information. Strict compliance with HIPAA and data protection laws is required. Strong cybersecurity is necessary to prevent breaches.
• Algorithmic Bias and Transparency: AI must be trained on diverse data to avoid biased recommendations. Regular audits and clear decision processes build trust among providers and patients.
• Clinician Oversight: AI is designed to support, not replace, clinicians. Staff need training on when and how to rely on AI, including understanding its limits, to prevent overdependence and maintain care quality.
• Patient Communication and Consent: Patients should be informed when AI is used in their care to promote transparency and trust, especially regarding automated assessments or decisions.

Urban and rural healthcare settings face different challenges. Urban hospitals, often under heavy patient loads, may focus on AI for managing crowds and speeding triage. Rural emergency departments might use AI more for diagnostic support where specialists are less available.

Implications for Medical Practice Administrators, Owners, and IT Managers in the U.S.

Healthcare leaders overseeing emergency departments can draw clear lessons from early AI triage experiences:

• Invest in AI Integration: Select AI tools that work smoothly with existing electronic health records and workflows to improve staff acceptance. For example, solutions like TriageGO that embed within health records maintain data flow.
• Focus on Staff Training and Engagement: Educate nurses and doctors about how AI functions, its limitations, and how to monitor its use. Gathering feedback from users helps tailor AI tools to practical needs.
• Leverage AI for Operational Analytics: Use AI to analyze patient flow, identify bottlenecks, and stratify risk. This aids resource distribution and planning.
• Plan for Compliance and Security: IT managers should prioritize HIPAA adherence, maintain transparent AI processes, and establish cybersecurity to protect patient information.
• Start with High-Impact Use Cases: Triage is a good starting point because it directly affects patient flow and safety. After success there, AI can expand to documentation help, predictive analytics, and managing resources.
• Collaborate with Vendors and Clinicians: Partnerships with AI developers, such as Simbo AI and Beckman Coulter (with TriageGO), provide ongoing technical support, updates, and customization for specific needs.
