目的探讨医院中药库药品管理现状并分析质控管理对策。方法通过改革前(2011年1月~2013年1月)和改革后(2013年2月~2015年2月)的对比研究,提出科学、有效的管理措施。结果改革管理前后药品不良事件比较,改革管理后,库存不足、药品丢失、药品过期与调配差错发生率显著低于改革管理前(均P0.05),质量评分显著提高(P0.05)。结论改革后管理措施有助于提高中药质量管理效果,减少药品不良事件,降低差错率,提高质量评分,值得应用。 相似文献

目的:通过病历中发生的不良事件及其风险度来评价病历质量,目的为加强病历环节和细节的质控,减少或杜绝病历中不良事件的发生,提高病历书写质量,保证医疗安全,减少医疗纠纷。方法:随机抽查2007-2010年某二级医院住院病历4837份,对其进行不良事件风险评估,对病历的终末质量和环节质量进行综合评价分析,找出影响医疗质量的相关联因素。结果:通过对某二级医院2007-2010年随机抽查的终末病历和病房中运行病历的不良事件风险评估,数据经过统计学处理后P值<0.01,说明总的病历中不良事件发生率年度间逐年减少,有极为显著的差别,证明此种病历评价方法切实可行。结论:病历中不良事件风险评估,是减少病历中不良事件发生的有效办法,可以消除病历书写中存在的医患矛盾和医疗纠纷隐患。 相似文献

In experiments on Black Sea skates (Raja clavata), the potential of the receptor epithelium of the ampullae of Lorenzini and spike activity of single nerve fibers connected to them were investigated during electrical and temperature stimulation. Usually the potential within the canal was between 0 and –2 mV, and the input resistance of the ampulla 250–400 k. Heating of the region of the receptor epithelium was accompanied by a negative wave of potential, an increase in input resistance, and inhibition of spike activity. With worsening of the animal's condition the transepithelial potential became positive (up to +10 mV) but the input resistance of the ampulla during stimulation with a positive current was nonlinear in some cases: a regenerative spike of positive polarity appeared in the channel. During heating, the spike response was sometimes reversed in sign. It is suggested that fluctuations of the transepithelial potential and spike responses to temperature stimulation reflect changes in the potential difference on the basal membrane of the receptor cells, which is described by a relationship of the Nernst's or Goldman's equation type.I.

Evolution of living organisms is closely connected with evolution of structure of the system of regulations and its mechanisms.
The functional ground of regulations is chemical signalization. As early as in unicellular organisms there is a set of signal
mechanisms providing their life activity and orientation in space and time. Subsequent evolution of ways of chemical signalization
followed the way of development of delivery pathways of chemical signal and development of mechanisms of its regulation. The
mechanism of chemical regulation of the signal interaction is discussed by the example of the specialized system of transduction
of signal from neuron to neuron, of effect of hormone on the epithelial cell and modulation of this effect. These mechanisms
are considered as the most important ways of the fine and precise adaptation of chemical signalization underlying functioning
of physiological systems and organs of the living organism 相似文献
