Emergency Departments see many patients every day and deal with complex cases. There are not enough beds for all patients who need to stay. Research from Missouri Baptist Medical Center shows that more patients coming in, slower treatment times, and delays in admitting or discharging patients all cause crowding. Crowding makes patients stay longer, lowers care quality, and makes staff tired.
For example, median wait times in U.S. Emergency Departments went up from 157 minutes in 2021 to 161 minutes in 2022. Some states reported waits as long as 330 minutes. At places like Missouri Baptist Medical Center, which admits about 36% of its 35,000 yearly patients, delays in finding and preparing beds make problems worse.
A key step in improving patient flow is the time between when a bed is ready and when nurses take over. This step causes about 39% of the delay in admitting patients. Poor communication between ED staff, inpatient units, and departments like Environmental Services can slow this process. This shows hospitals need better communication, faster problem-solving, and set time goals for each step in admitting patients.
AI technologies, like large language models and machine learning, can help make triage and patient flow better in Emergency Departments.
By using AI in triage and admission, Emergency Departments can better prioritize patients, lower delays, and make moving patients between units smoother. This is helpful since many nursing jobs are hard to fill. AI lets staff spend more time directly caring for patients.
One big cause of delay in Emergency Departments is not knowing when a bed is free and ready for new patients. A 9-month study at Missouri Baptist Medical Center showed that setting clear time goals helped reduce waiting times between steps:
These gains happened because teams like environmental services, nursing, and admissions worked closely together and quickly flagged delays. Using technology to watch over bed use and readiness helped teams get alerts instantly and act faster.
AI bed management systems gather data from different hospital parts. They use predictions to tell when beds will be free and how many patients will need admission. This helps hospitals plan better and cuts wait times in the Emergency Department.
AI-driven workflow automation helps Emergency Departments run more smoothly. It uses AI to analyze data, predict results, and do routine tasks automatically while improving communication. This helps both staff and administrators.
Automation with AI reduces communication problems, errors, and speeds important handoffs. Hospital leaders get more steady patient flow, less crowding, and better use of resources.
Conditions like heart failure, COPD, asthma, and muscle or bone problems often cause avoidable Emergency Department visits. Managing these patients outside the ED can ease crowding and cut costs.
Companies such as Hinge Health use large language models to send personalized messages and keep patients involved with their care plans. This improves health results and lowers unneeded ED visits by managing health before it gets worse.
AI connects patient history, recent visits, and care guidelines to create custom care steps. This helps stop emergencies before they start, keeping patients out of the hospital.
Digital tools to engage patients work well but not all groups use them equally. A study of over 1.28 million Emergency Department visits found that only 17.4% of patients used online patient portals during their visit. Men, Black patients, and those without commercial insurance used portals less.
Hospitals in diverse areas need to work on digital fairness. This means helping all patients get access to mobile devices, offering support in many languages, and training staff to promote digital tools. This will help more people benefit from AI-based communication.
To use AI triage and resource management well, hospital leaders must train doctors, nurses, and other staff. AI tools need to fit well into current workflows. Protecting patient data and making AI choices clear are important to earn trust and keep patients safe.
Working together, technology makers, clinicians, and administrators can improve AI tools for emergency care and solve real problems hospitals face.
Emergency Departments, especially in community hospitals, need efficient systems to handle more patients and fewer staff. AI-powered triage and bed management tools can help reduce patient wait times, sort patients by need better, and use resources smartly.
Using AI with clear time goals and automating key tasks like intake, notes, and alerts can lower patient stay times, reduce crowding, and keep care safer and more organized.
Successful AI use needs planning based on data, staff training, and making sure all patients can access digital tools. With careful use, AI can make emergency care faster and better for patients and care teams across the country.
Pre-ED triage helps reduce unnecessary emergency department (ED) visits by guiding patients to the appropriate level of care using AI chatbots and 911-integrated triage services. It enhances patient decision-making and system efficiency by diverting low-acuity cases to virtual or home-based care, thus lowering healthcare costs and avoiding ED overcrowding.
911-integrated triage services like MD Ally and RightSite assess the severity of conditions during emergency calls and redirect low-acuity cases to virtual care options. They provide additional support like prescription assistance or transportation, helping to reduce avoidable ED visits and EMS usage, while aligning incentives between payers and emergency services.
LLMs enable personalized messaging and communication that improve patient engagement and clinical outcomes for ambulatory-sensitive conditions (ASCs) such as heart failure or COPD. Startups like Hinge Health use LLMs to tailor interactions and reduce unnecessary ED visits by managing chronic illnesses effectively outside hospital settings.
AI tools like Stochastic and Mednition support clinical decision-making by accurately classifying patient acuity and identifying high-risk patients early, improving resource allocation. AI-driven command centers optimize throughput, predict crowding, and balance staffing, easing bottlenecks to maintain efficient patient flow and timely care delivery.
LLMs can track patient progress against clinical guidelines in real time, flag delays (e.g., missing tests), and prioritize care. This granular patient-level monitoring can accelerate appropriate discharges and optimize bed management beyond operational metrics, improving adherence to care standards and reducing crowding.
Apps like Fabric engage patients before and during ED visits by enabling pre-registration, providing visit progress updates, and offering digital discharge processes. These tools reduce documentation burden on staff, improve patient navigation, and decrease the rate of patients leaving before being seen, thereby improving care continuity and satisfaction.
Conversational AI agents can collect patient history, triage severity, pre-populate clinical notes, screen for social determinants of health, and guide patients through their ED stay in understandable terms. This reduces nurse workload, shortens wait times, and enhances communication, supporting better patient engagement and streamlined workflows.
Viz.ai uses deep learning to analyze imaging (CT, ECG) for rapid stroke and vascular care decisions, reducing treatment time. Heartflow assesses cardiac blood flow noninvasively via AI-driven CT analysis to avoid invasive procedures and expedite chest pain patient discharge, enhancing safety and efficiency in ED triage.
Unlike 911 triage solutions where ED diversions are clearly measurable, digital front door tools face complex attribution challenges as they need to demonstrate impact on patient behavior and healthcare utilization earlier in the care journey, requiring alignment of incentives across stakeholders and longitudinal outcome tracking.
Studies show low patient portal usage during ED visits, especially among males, Black patients, and uninsured populations, which limits the benefits of digital tools. Promoting equitable access to digital engagement before and during ED visits enhances participation, improves communication, and supports better health outcomes across diverse patient groups.
