Improving emergency department patient flow
Paul Richard Edwin Jarvis 대한응급의학회 2016 Clinical and Experimental Emergency Medicine Vol.3 No.2
Emergency departments (ED) face significant challenges in delivering high quality and timely patient care on an ever-present background of increasing patient numbers and limited hospital resources. A mismatch between patient demand and the ED’s capacity to deliver care often leads to poor patient flow and departmental crowding. These are associated with reduction in the quality of the care delivered and poor patient outcomes. A literature review was performed to identify evidence-based strategies to reduce the amount of time patients spend in the ED in order to improve patient flow and reduce crowding in the ED. The use of doctor triage, rapid assessment, streaming and the co-location of a primary care clinician in the ED have all been shown to improve patient flow. In addition, when used effectively point of care testing has been shown to reduce patient time in the ED. Patient flow and departmental crowding can be improved by implementing new patterns of working and introducing new technologies such as point of care testing in the ED.

An integrated waste management approach for irradiated graphite was developed during the European Commission project 'Treatment and Disposal of Irradiated Graphite and other Carbonaceous Waste'. This included the identification of potential options for the management of irradiated graphite, taking account of storage, retrieval, treatment and disposal methods. This paper describes how these options can be assessed using multi-criteria decision analysis (MCDA) for a case study relating to a generic power reactor. Criteria have been defined to account for safety, environmental, economic and socio-political factors, including radiological impact, resource usage, economic costs and risks. The impact of each option against each criterion has been assessed using data from the project and the wider literature. A linear additive approach has been used to convert the calculated impacts to scores. To account for the relative importance of the criteria, example weightings were allocated. This application has shown that MCDA approaches can be used to support complex decisions regarding irradiated graphite management, accounting for a wide range of criteria. Use of this approach by individual countries or organisations will need to account for the specific options, scores, weightings and constraints that apply, based on their national strategies, regulatory requirements and public acceptability.

Development of integrated waste management options for irradiated graphite
Alan Wareing,Liam Abrahamsen-Mills,Linda Fowler,Michael Grave,Richard Jarvis,Martin Metcalfe,Simon Norris,Anthony William Banford 한국원자력학회 2017 Nuclear Engineering and Technology Vol.49 No.5
The European Treatment and Disposal of Irradiated Graphite and other Carbonaceous Waste projectsought to develop best practices in the retrieval, treatment, and disposal of irradiated graphite includingother irradiated carbonaceous waste such as structural material made of graphite, nongraphitized carbonbricks, and fuel coatings. Emphasis was given on legacy irradiated graphite, as this represents a significantinventory in respective national waste management programs. This paper provides an overview ofthe characteristics of graphite irradiated during its use, primarily as a moderator material, within nuclearreactors. It describes the potential techniques applicable to the retrieval, treatment, recycling/reuse, anddisposal of these graphite wastes. Considering the lifecycle of nuclear graphite, from manufacture to finaldisposal, a number of waste management options have been developed. These options consider thetechniques and technologies required to address each stage of the lifecycle, such as segregation, treatment,recycle, and ultimate disposal in a radioactive waste repository, providing a toolbox to aid operatorsand regulators to determine the most appropriate management strategy. It is noted that nationalwaste management programs currently have, or are in the process of developing, respective approachesto irradiated graphite management. The output of the Treatment and Disposal of Irradiated Graphite andother Carbonaceous Waste project is intended to aid these considerations, rather than dictate them.
