• Abstract summary: The underlying factors leading to ED crowding are numerous, varied, and complex. Lack of in-hospital beds is frequently attributed as the primary reason for crowding. ED's dependencies on other ancillary resources, including imaging, consults, and labs, also contribute to crowding.

• Abstract: Emergency Department (ED) overcrowding continues to be a public health issue as well as a patient safety issue. The underlying factors leading to ED crowding are numerous, varied, and complex. Although lack of in-hospital beds is frequently attributed as the primary reason for crowding, ED's dependencies on other ancillary resources, including imaging, consults, and labs, also contribute to crowding. Using retrospective data associated with imaging, including delays, processing time, and the number of image orders, from a large tier 1 trauma center, we developed a discrete event simulation model to identify the impact of the imaging delays and bundling image orders on patient time in the ED. Results from sensitivity analysis show that reducing the delays associated with imaging and bundling as few as 10% of imaging orders for certain patients can significantly (p-value < 0.05) reduce the time a patient spends in the ED.

  We leverage a state-of-the-art noninvasive computer vision system based on depth imaging to characterize ICU visitations and patients' mobility. We found an association between deteriorating patient acuity and the incidence of delirium with increased visitations. Our findings highlight the feasibility and potential of using noninvasive autonomous systems to monitor ICU patients.

  A hospital readmission is when a patient who was discharged from the hospital is admitted again for the same or related care within a certain period. We use state-of-the-art machine learning approaches in time-series analysis and natural language processing to predict Unplanned Readmissions in ICUs.

  Emergency Departments (EDs) are a fundamental element of the Portuguese National Health Service. Forecasting the number of patients using the services is particularly challenging. This paper describes a novel deep learning architecture, the Temporal Fusion Transformer. We have concluded that patient volume can be forecasted with a Mean Absolute Percentage Error (MAPE) of 5.90% for Portugal's Health Regional Areas (HRA) and a Root Mean Squared Error (RMSE) of 84.4102 people/day.

• Effect of different patient peak arrivals on an Emergency Department via discrete event simulation [0.0]
  We propose a model to study the patient flows through a medium-size ED located in a region of Central Italy recently hit by a severe earthquake. In particular, our aim is to simulate unusual ED conditions, corresponding to critical events (like a natural disaster) that cause a sudden spike in the number of patient arrivals. The model provides a valid decision support system for the ED managers also in defining specific emergency plans to be activated in case of mass casualty disasters.
