Emergency departments (EDs) in the United States have a hard job giving timely and proper care to patients with urgent medical problems. One important step that affects patient outcomes and how well the department runs is the triage process. Triage means sorting and deciding which patients need care first based on how serious their symptoms are. In many emergency departments, differences in how triage is done can change how fast patients get the right care. This affects patient safety and their satisfaction.
This article talks about why standardizing triage practices in US emergency services is important to reduce differences and improve patient care. It looks at recent studies and actions from countries like Canada, Singapore, and Japan. These countries showed clear benefits from making triage systems uniform and using electronic and AI-based tools to help decide. These examples matter to hospital managers, owners, and IT staff in the US who want to improve emergency department work.
Emergency departments often have many patients and need to quickly decide who to treat first. Triage is the gatekeeper—it decides who needs care right away and who can wait without harm. But triage is often based on opinions. It depends on how experienced the nurse or doctor is, how busy they are, and what resources are available.
Research shows this leads to varied results in triage. Sometimes patients are given higher urgency than needed (over-triage), or lower urgency than needed (under-triage), which can delay care. Both cases cause problems. Over-triage can crowd the hospital and waste resources. Under-triage can delay life-saving care.
For example, a study in seven emergency departments in Ontario, Canada checked what happened when they used the electronic Canadian Triage and Acuity Scale (eCTAS). This is a computer system that helps standardize triage decisions in real time. Before eCTAS, triage nurses and an audit team agreed exactly 75.4% of the time. After eCTAS, they agreed 92.7% of the time. This showed better consistency and trust in triage scores.
The study also found big drops in over-triage (from 12.0% to 5.1%) and under-triage (from 12.6% to 2.2%). This means the system helped give more accurate triage levels based on patient needs. The median triage time increased by only 35 seconds, which was seen as an okay tradeoff for better safety.
Standardizing triage like this helps use resources better and makes patient movement through the emergency department smoother, which is very important for busy US hospitals with many patients.
Singapore General Hospital also worked to lower triage wait time in their busy emergency department. They serve more than 125,000 patients each year. Before making changes, the average wait to triage was about 18 minutes for 315 walk-in patients daily.
They used a Plan-Do-Study-Act (PDSA) method and made several changes. These included improving triage rules, having senior nurses quickly check for the most seriously ill patients with a fast “eyeball” triage, and creating a triage nurse clinician role to support and coach less experienced nurses. These changes cut average wait time by 28%, from 18 minutes to 13 minutes. They also reduced variation in wait times by 25%. Staff said the clearer rules and extra support helped.
For US hospital managers, this shows how important it is to keep checking the triage process and develop staff skills. Reducing differences in triage shortens patient wait time and improves how accurately and safely triage decisions are made, helping patients get better care.
New technology like artificial intelligence (AI) and workflow automation offers ways to reduce differences and inefficiency in triage. Some recent studies tested AI models to help emergency workers make better triage decisions with good results.
One study used OpenAI’s GPT language models with Retrieval Augmented Generation (RAG) to assign triage levels in emergency practice examples. GPT-3.5 with RAG got the correct triage level 70% of the time. This was much better than emergency medical technicians (EMTs), who got 35-38%, and emergency doctors, with 47-50%. The AI also cut under-triage rates to 8%, compared to 33% and 39% without AI help.
These results show AI can act as a fair helper in triage. It can reduce human errors caused by different experience or judgment. US emergency departments could use AI to support decisions, prioritize resources better, and lower care delays.
On top of AI, phone automation like Simbo AI helps with patient calls and questions. It can schedule appointments automatically, answer common questions, and collect patient info before they come in. This lowers phone workload for hospital staff and makes patient communication faster. This helps patient flow and experience.
Using AI tools with automated phone systems can make the patient journey from arrival or call to clinical check smoother and more consistent. IT managers and hospital leaders should think about adopting these tools to improve efficiency and safety in busy emergency departments.
Programs like the electronic Canadian Triage and Acuity Scale (eCTAS) show how decision support software used during triage can help. This is important in the US where many patients come in and nurses and doctors have different levels of experience.
eCTAS uses a set list of 170 patient complaints plus triage templates that guide users through vital signs and other clinical details. It helped improve agreement on triage scoring between different hospitals, including rural and teaching hospitals.
US hospital leaders who put in similar electronic systems might see these results:
Training and support for triage nurses is key. The Ontario eCTAS study showed improvements worked in various emergency departments and that staff accepted the electronic system well.
US hospital systems should plan carefully for rollout with strong training and ways to get user feedback. Also, they could look for state or federal funds that help improve health IT.
The Singapore study also found that nurse staffing levels mattered a lot for triage wait times. When there were not enough nurses during the busiest times, waits grew longer and patient flow was blocked.
They created a triage nurse clinician role to supervise and help nurses during busy times. This helped lower differences in triage and sped up the process.
US emergency departments could try similar staffing models. Having more experienced staff support triage teams during busy times can:
Matching staff schedules to patient arrival patterns reduces differences and cuts wait times.
Hospital managers, owners, and IT staff in the US should think about these steps to improve triage and patient outcomes:
Triage is an important step that affects patient safety, care quality, and how well emergency departments run. Studies from other countries show that differences in triage are a common problem that can be fixed with standard rules, electronic tools, and AI technology.
Hospital leaders and IT managers in the US can learn from these examples to improve their triage systems. Using proven electronic triage tools, AI help, better staffing, and automation can improve patient results, cut wait times, and support nurses and doctors.
It is important for leaders to put effort and money into these technologies and processes. That way emergency care can be safe, timely, and right for all patients who need help fast.
The primary goal is to enhance the overall efficiency of patient flow, reducing congestion and wait times, which ultimately leads to improved patient care and experience in emergency departments.
A series of Plan-Do-Study-Act (PDSA) cycles were implemented to identify and address key issues affecting wait times, allowing for targeted interventions.
The baseline average wait time to triage was 18 minutes, which was reduced to 13 minutes post-implementation, reflecting a 28% improvement.
Staffing was identified as a critical factor; inconsistent triage nurse availability aligned with patient arrival trends often led to prolonged wait times.
‘Eyeball’ triage involves quick assessments by senior nurses to identify patients needing immediate care, facilitating faster patient transfers to care areas.
The triage nurse clinician role served to guide less experienced nurses and ensure adequate staffing, which improved triage efficiency.
Key upstream processes included patient registration and triaging, both of which occur before patient consultation by doctors.
Systemic issues included limited physical space in the triage area and insufficient ancillary staff to assist with non-triage-related tasks during peak periods.
Standardized triage criteria were implemented to reduce variability in outcomes, ensuring faster and more consistent triage decisions.
Reducing non-urgent point of care tests and exploring the implementation of AI-infused triage assistants were recommended to enhance efficiency further.
