“…Likewise, researchers are advised to take into account the methodological trends regarding process improvement in emergency departments. For example, over the recent years, there has been a growing tendency to undertake multi-objective interventions as cited in Easter et al [25] and Ajmi et al [83]. Furthermore, there has been a downward trend in recent years concerning the use of CQI-based approaches which may be explained by the adoption of more robust approaches like LM.…”

“…OR methods were also applied in a single form for dealing with the extended LOS within EDs. For example, Ajmi et al [83] developed an agent-based dynamic optimization model for improving several performance indicators (LOS, remaining patient care load, and cumulative waiting time) in EDs. OR-based studies addressing long LOS are evidenced in Chan et al [91], Derni et al [87], Liu et al [95], and Oueida et al [86,96].…”

“…Similar objectives were pursued by Bordoloi and Beach [151] who, unlike the previous work, used optimization models encompassing the entire patient journey within the ED. Single OR-based approaches are also extensively used in Ajmi et al [83], Derni et al [87], Leo et al [153], Meng et al [152], Nezamoddini and Khasawneh [154], and Oueida et al [96]. Other non-hybrid methods that have been employed for tackling this ED deficiency are as follows: REACT [91], pivot nursing [92], process redesign [94,156], regression [157,158], nurse navigator [160], Iowa model of evidence-based practice [161], CQI [81,155], and ED dashboard/reporting [98].…”

“…Other contributing studies utilizing regression are available at Hu et al [192] and Van der Veen et al [74]. Less explored single approaches include: agent-based dynamic optimization [83], process redesign [94], Fulbrook et al [160], integer programming [154], SCLP [193], and Iowa model of evidence-base practice [161].

“…Other single techniques were used for tackling lengthy patient journey times within EDs; however, their application has been poorly explored as further evidenced throughout the literature. These include optimization models [83,151], petri nets [87,96], process redesign [94,156], mixed integer programming [208], nurse navigator [160], acute care model [209], critical pathways [210], fast track protocols [211], Iowa model of evidence-based practice [161], and regression analysis [75]. Table 6 depicts the articles focusing on diminishing the number of patients who leave the ED without being seen.…”

The most commonly used techniques for addressing each Emergency Department (ED) problem (overcrowding, prolonged waiting time, extended length of stay, excessive patient flow time, and high left-without-being-seen (LWBS) rates) were specified to provide healthcare managers and researchers with a useful framework for effectively solving these operational deficiencies. Finally, we identified the existing research tendencies and highlighted opportunities for future work. We implemented the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology to undertake a review including scholarly articles published between April 1993 and October 2019. The selected papers were categorized considering the leading ED problems and publication year. Two hundred and three (203) papers distributed in 120 journals were found to meet the inclusion criteria. Furthermore, computer simulation and lean manufacturing were concluded to be the most prominent approaches for addressing the leading operational problems in EDs. In future interventions, ED administrators and researchers are widely advised to combine Operations Research (OR) methods, quality-based techniques, and data-driven approaches for upgrading the performance of EDs. On a different tack, more interventions are required for tackling overcrowding and high left-without-being-seen rates.

The Emergency Department (ED) represents the first stage of the path for some patients in a hospital. The JUNEAU project aims to propose a Digital Twin (DT) for the ED to both visualise the service behaviour in quasi real-time, forecast and anticipate its behaviour to control the "Emergency throughput time" indicator. This DT will be centred on the "patient pathway" view, which needs to first precise necessary data and information and decision support. The project will tackle this issue with a particular attention on exploring the DT architecture (with the help or holonic architecture), on coupling centralised and decentralised approaches to obtain a model as close as possible to the system dynamics and on managing DT evolution in a complex environment.

Operating Room Performance Optimization Metrics: a Systematic Review

et al. 2023

View full text Add to dashboard Cite

Literature proposes numerous initiatives for optimization of the Operating Room (OR). Despite multiple suggested strategies for the optimization of workflow on the OR, its patients and (medical) staff, no uniform description of ‘optimization’ has been adopted. This makes it difficult to evaluate the proposed optimization strategies. In particular, the metrics used to quantify OR performance are diverse so that assessing the impact of suggested approaches is complex or even impossible. To secure a higher implementation success rate of optimisation strategies in practice we believe OR optimisation and its quantification should be further investigated. We aim to provide an inventory of the metrics and methods used to optimise the OR by the means of a structured literature study. We observe that several aspects of OR performance are unaddressed in literature, and no studies account for possible interactions between metrics of quality and efficiency. We conclude that a systems approach is needed to align metrics across different elements of OR performance, and that the wellbeing of healthcare professionals is underrepresented in current optimisation approaches.
