目的 研究三级医院床位和人员的适宜规模,控制医院过度发展和资源浪费。方法 以北京市三级医院为研究样本,确定投入-产出指标,利用DEAP(2.1)软件,分析1991—2011年北京市三级医院规模报酬状态,找出规模报酬拐点,从而确定三级医院适宜规模。结果 2011年,41所医院中,有39家医院处于DEA有效状态,2家医院处于DEA非有效状态;时间序列纵向分析中,有18家医院出现规模报酬拐点。北京市三级综合医院的适宜规模的严格控制标准为:床位606张,95%CI:(425,786),在职职工1 219人,95%CI:(797,1 641);较宽松的控制标准为:床位1 058张,95%CI:(831,1 284),在职职工2 236人,95%CI:(1 716,2 757)。结论 研究得到了三级公立医院的规模控制标准,要严格控制公立医院的规模和特大型医院的数量,注重提高医院的运行效率,缩短平均住院日。 相似文献

AbstractQuantitative risk assessment (QRA) approaches systematically evaluate the likelihood, impacts, and risk of adverse events. QRA using fault tree analysis (FTA) is based on the assumptions that failure events have crisp probabilities and they are statistically independent. The crisp probabilities of the events are often absent, which leads to data uncertainty. However, the independence assumption leads to model uncertainty. Experts’ knowledge can be utilized to obtain unknown failure data; however, this process itself is subject to different issues such as imprecision, incompleteness, and lack of consensus. For this reason, to minimize the overall uncertainty in QRA, in addition to addressing the uncertainties in the knowledge, it is equally important to combine the opinions of multiple experts and update prior beliefs based on new evidence. In this article, a novel methodology is proposed for QRA by combining fuzzy set theory and evidence theory with Bayesian networks to describe the uncertainties, aggregate experts’ opinions, and update prior probabilities when new evidences become available. Additionally, sensitivity analysis is performed to identify the most critical events in the FTA. The effectiveness of the proposed approach has been demonstrated via application to a practical system. 相似文献

Concerns about terrorist use of biological agents have increased at state and federal levels and in the popular press. Vulnerability of U.S. agricultural assets to bioterrorism has received less attention. A bioterrorist could use the U.S. food supply system to deliver a bioagent to a human target or use a bioagent to destroy it's inputs or infrastructure. Establishing effective agriculture security programs requires condensing generalizations about such bioterrorist threats into specific attack scenarios. This paper suggests a two-stage process to achieve this: problem formulation to define and rank scenarios, then quantitative risk assessment of selected, more highly ranked, scenarios. The quantitative component is illustrated for two specific scenarios: the actual 1984 Rajneeshee incident in Oregon and a hypothetical release of oral anthrax into the food supply system. The fault tree analysis of these scenarios suggests that the food supply system may be a less than optimal bioagent delivery mechanism, particularly if the objective is a mass casualty attack, as a number of events must occur simultaneously with reasonable probability if a bioagent is likely to be deployed effectively. In addition, an environmentally stable bioagent would be required if only the food system were used to deliver it to human consumers, but early detection of an intentional release common bioagent may be difficult absent specific intelligence or “unusual” epidemiological circumstances. 相似文献

In the context of climate change, the effects of prolonged or more severe droughts on pest and pathogen damage are a major concern for forest ecosystems. To date, there is great uncertainty about the direction, magnitude and sources of variation in responses to drought by insects and fungi. We report the outcomes of a meta‐analysis of 100 pairwise comparisons of insect pest or pathogen damage to water‐stressed and control trees from 40 publications. The type of feeding substrate for insects and fungi and the water stress severity emerged as the main factors influencing the level of damage in water‐stressed trees. Overall, primary damaging agents living in wood caused significantly lower damage to the water‐stressed trees compared with the control, whereas primary pests and pathogens living on foliage caused more damage to water‐stressed trees, in all cases irrespective of stress severity. In contrast, damage by secondary agents increased with stress severity, which was best estimated by the ratio between the predawn leaf water potential in stressed trees and the xylem pressure inducing 50% loss in hydraulic conductance due to cavitation, a species‐specific index of drought tolerance. Insect and fungus feeding behaviour, affected tree part, and water stress severity are therefore proposed as three important predictors of forest damage in drought conditions. 相似文献

目的:近年来,医疗纠纷屡见不鲜,其中不乏军队医院。为此,我们对目前部队医院的医疗风险管理情况进行分析,深入总结军队医院管理存在的问题,并提出相应的对策以加强部队医院医疗风险的防范工作。方法:采取调查问卷方法对10所部队医院的一线医护人员就医疗风险相关问题进行调查,并对结果进行分析。结果:工龄低于5年的医务人员发生医疗风险的比率高于工作5年以上的人员;外科和妇产科医疗风险发生率较高;三级甲等医院医疗风险管理体系较三级乙等更完善。医院的管理制度、医务人员的工龄、科室的设置、风险教育及工作量等均与医疗风险的发生有着密切的关系。结论:部队医院应建立健全的风险预警系统与评价体系,提高医院对医疗风险的管理能力。医务人员应加强风险意识和法制意识,重视医患沟通,以促进医患关系和谐,从而减少或避免医疗纠纷的发生。 相似文献
