Summary: Increasing flexibility in assigning emergency department patients to inpatient wards can shorten boarding time, but high levels of flexibility can damage quality of care, staff satisfaction, and implementation complexity. We propose a partially flexible routing strategy that balances the trade-offs by using a bipartite graph algorithm, offering comparable boarding times, high quality of care, simplicity, and staff satisfaction. Simulation results show that our proposed policy performs similarly to a fully flexible design in reducing boarding time under various system settings.

Summary: Long boarding times have been identified as a major cause of emergency department crowding. This paper proposes a method to estimate hospital admission probabilities using logistic regression techniques and develops two mathematical decision models to determine when to request a bed early. The simulation model using real hospital data shows that both policies can bring substantial benefits, especially in high-demand situations.

Summary: Emergency department overcrowding is a serious problem, and accurate patient arrival forecasting can help better allocate ED personnel and medical resources. This study combined calendar and meteorological information and used ten machine learning methods to forecast patient arrivals, with results showing better performance compared to traditional models.

Summary: This study focuses on estimating the probability distribution of individual patient waiting times in an emergency department using a machine learning approach. The proposed method provides more accurate probabilistic forecasts compared to existing methods that only focus on point forecasts. This can improve overall patient satisfaction and prevent patient abandonment.

Summary: This study examines the impact of intervention policies on patient flow in emergency departments during the COVID-19 pandemic. The results show that adding extra treatment rooms improves overall patient flow parameters, while adding a waiting zone only benefits contaminated patient flow. However, the potential disadvantages for ordinary patients should be considered when implementing such interventions.

Summary: In the emergency department, the order in which patients are served does not strictly follow the first-come, first-served principle. Discharged patients are prioritized over admitted patients, even among patients of the same triage level. Decision makers in the emergency department apply urgency-specific delay-dependent prioritization when choosing the next patient for treatment. The level of emergency department blocking also plays a role in patient prioritization.

Summary: The study showed that the implementation of sepsis surveillance with decision support did not lead to improved sepsis care compliance or patient outcomes. While there was an increase in care bundle compliance during the study period, the intervention did not show any significant association with improved outcomes.

Summary: The study evaluated the impact of Rapid Medical Evaluation (RME) on patient flow in the Emergency Department (ED) and found that implementing RME helped reduce the time patients spend in the ED Treatment Room, improved patient throughput, and decreased Door-to-Provider time during busy periods in the ED.

Summary: The study found that patient satisfaction and service perceptions are significantly influenced by the behavior and communication networks of healthcare providers. Patients value physical proximity and continuous monitoring of their health conditions by doctors and providers, as well as desire to actively participate in the communication network. Additionally, patients perceive positively when doctors lead the communication network within teams for more effective conversations.
