AI Outperforms Nurses in Predicting Hospital Admissions, Promising to Reduce ER Overcrowding

AI Revolutionizes Emergency Department Admissions Prediction

A groundbreaking study conducted by the Mount Sinai Health System has demonstrated that artificial intelligence (AI) can significantly improve the prediction of hospital admissions in emergency departments (EDs). The research, published in the July 9 online issue of Mayo Clinic Proceedings: Digital Health, showcases AI's potential to enhance patient care, reduce overcrowding, and optimize resource allocation in hospitals .

Study Design and Findings

The study, one of the largest prospective evaluations of AI in emergency settings to date, involved collaboration with over 500 ED nurses across Mount Sinai's seven-hospital system. Researchers evaluated a machine learning model trained on data from more than 1.8 million past patient visits 2

Key findings include:

1. The AI model achieved 85% accuracy in predicting hospital admissions, slightly outperforming the 81% accuracy of experienced nurses 4

   .
2. The AI system performed consistently across diverse hospital settings, including urban and suburban locations.
3. Surprisingly, combining human and machine predictions did not significantly boost accuracy, indicating the AI system's strong predictive capabilities .

Implications for Emergency Care

The AI-driven approach could:

1. Enhance patient care and experience
2. Reduce overcrowding and "boarding" (when admitted patients remain in the ED due to unavailable beds)
3. Enable more efficient resource allocation

AI as a Supportive Tool

Dr. Eyal Klang, Chief of Generative AI in the Windreich Department of Artificial Intelligence and Human Health at the Icahn School of Medicine at Mount Sinai, emphasized that the AI model is designed to support, not replace, clinical decision-making: "The strength of this approach is its ability to turn complex data into timely, actionable insights for clinical teams—freeing them up to focus less on logistics and more on delivering the personal, compassionate care that only humans can provide" .

Future Directions

While the study was limited to one health system over a two-month period, the team is optimistic about its potential. The next phase involves implementing the AI model into real-time workflows and measuring outcomes such as reduced boarding times, improved patient flow, and operational efficiency 2

Robbie Freeman, DNP, RN, NE-BC3, Chief Digital Transformation Officer at Mount Sinai Health System, concluded: "It's inspiring to see AI emerge not as a futuristic idea, but as a practical, real-world solution shaped by the people delivering care every day" 3
