shake table investigation on the seismic performance of Hospital Equipment supported on wheels casters
Earthquake Engineering & Structural Dynamics, 2017Co-Authors: Farzad Nikfar, Dimitrios KonstantinidisAbstract:Summary This paper presents an experimental investigation on the seismic response of medical Equipment supported on wheels and/or casters. Two pieces of Equipment were tested: a large ultrasound machine and a cart carrying smaller medical Equipment. In the first phase, the resistance of the wheels and casters of the Equipment was characterized through a controlled-displacement procedure on the shake table. In the second phase, an extensive shake table test program was carried out to investigate the seismic response of the Equipment. The input signals for the shake table tests included floor motions of a four-story steel braced-frame Hospital designed to satisfy seismic requirements of a site in the Los Angeles area. The results of 96 shake table tests reported in this study include the seismic performance of the Equipment under both unlocked and locked conditions, located on various floor levels of the building. It was observed that engaging the casters' locking mechanism does not necessarily decrease the relative displacement. The displacement response was sensitive to the excitation intensity and the orientation of the Equipment with respect to the input excitation. Based on the experimental observations, appropriate structural engineering demand parameters associated with the relative displacement and relative velocity demands of the Equipment are proposed and used to develop conditional probability curves. Finally, in an effort to extend the results of this experimental study to similar Equipment on wheels/casters, the performance of a simple numerical model in predicting the peak seismic demands is evaluated.

Funding of Hospital Equipment underfunded by £8m in Scotland
BMJ, 2001Co-Authors: Bryan ChristieAbstract:Hospitals in Scotland are failing to invest adequately in medical Equipment, which could result in putting patients at risk, says a report from the Auditor General for Scotland. It has recommended the establishment of a rolling programme of planned replacement. Underfunding of around £8m ($12m) was identified in 1997-8. Although the report acknowledges that figures for one year need to be treated with caution, it added: “Our survey findings suggest that across Scotland, expenditure on new …

Spending on Hospital Equipment is underfunded by ?8m in Scotland.
BMJ, 2001Co-Authors: Bryan ChristieAbstract:Hospitals in Scotland are failing to invest adequately in medical Equipment, which could result in putting patients at risk, says a report from the auditor general for Scotland. It has recommended the establishment of a rolling programme of planned replacement. Underfunding of around £8m ($12m) was identified in 1997-8. Although the report acknowledges that figures for one year need to be treated with caution, it added: “Our survey findings suggest that across Scotland, expenditure on new and replacement medical Equipment is failing to match depreciation and that trusts are not replacing items of medical Equipment when they come to the end of their useful lives.” The report also found that more than 40% of health trusts had no formal training policies for using medical Equipment. That was a matter of concern because the Medical Devices Agency had produced figures showing that patients were 3-10 times more likely to be at risk from error by users than from faulty Equipment.

French national centre for Hospital Equipment
Journal of Medical Engineering & Technology, 2009Co-Authors: Louis BlancheAbstract:With their usual thoroughness the French have attacked the proliferation of customised Equipment produced by various Research and Development Centres by establishing a National Centre for Hospital Equipment. This has been recently reported in the Revue Europeenne de Biotechnologie Medicale [1].

Hospital Equipment management decision support system based on data mining technology
Chinese Medical Equipment Journal, 2005Co-Authors: Yu Chun-huaAbstract:With the rapid increasing of data traditional Equipment management information system based on relational database has difficulty satisfying the needs for decision-making. Data mining technology can find useful information for decision-making from massive history data thus it has been applied widely. In this paper decision tree method is applied to data mining in Hospital Equipment management information database in order to find the rules among the Equipment consuming, Equipment storage and Equipment supply and to provide an assistant decision-making means for managers.
