Sustained clinical improvement is unlikely without appropriate measuring and reporting techniques. Clinical indicators are tools to help assess whether a standard of care is being met. They are used to evaluate the potential to improve the care provided by healthcare organisations(HCOs). The analysis and reporting of these indicators for the Australian Council on Healthcare Standards have used a methodology which estimates, for each of the 338 clinical indicators, the gains in the system that would result from shifting the mean proportion to the 20 th centile. The results are used to provide a relative measure to help prioritise quality improvement activity within clinical areas, rather than simply focus on "poorer performing" HCOs. The method draws attention to clinical areas exhibiting larger between-HCO variation and affecting larger numbers of patients. HCOs report data in six-month periods, resulting in estimated clinical indicator proportions which may be affected by small samples and sampling variation. Failing to address such issues would result in HCOs exhibiting extremely small and large estimated proportions and inflated estimates of the potential gains in the system. This paper describes the 20 th centile method of calculating potential gains for the healthcare system by using Bayesian hierarchical models and shrinkage estimators to correct for the effects of sampling variation, and provides an example case in Emergency Medicine as well as example expert commentary from colleges based upon the reports. The application of these Bayesian methods enables all collated data to be used, irrespective of an HCO's size, and facilitates more realistic estimates of potential system gains.

本文仅就微机在数据采集、编辑、处理中的应用(附带‘主机’)进行了讨论。由野外装有仪器的混凝土板上读出的以温度和电流形式的数值用常用的写入程序输入并储存在‘软盘’上。数据被核对、修正和预处理后由文字处理机提交‘主机’,由‘主机’输出再返回到微机,由微机进行进一步处理。最后一步,将正文和数据格式化并按‘Copy—ready’格式打印出最终报告,并用微机绘制图表。微机的利用使数据处理大大简化,极大地提高了工程中数据处理中的精度和效率。在数据输入主机之前进行预处理,可节省联机时间所造成的浪费约5,000美元。此外,通过利用微机的文字处理和绘图功能也节省了制图和雇用秘书所需要的费用。

World Journal of Experimental Medicine 2015年第2期5卷 50-63页

作者： Dubravka Kojic Benedikt H Siegler Florian Uhle Christoph Lichtenstern peter p Nawroth Markus A Weigand Stefan Hofer Thorsten Brenner Department of Anesthesiology Heidelberg University Hospital Department of Internal Medicine I and Clinical Chemistry Heidelberg University Hospital

Beside many efforts to improve outcome, sepsis is still one of the most frequent causes of death in critically ill patients. It is the most common condition with high mortality in intensive care units. The complexity of the septic syndrome comprises immunological aspects- i.e.,sepsis induced immunosuppression- but is not restricted to this fact in modern concepts. So far, exact mechanisms and variables determining outcome and mortality stay unclear. Since there is no typical risk profile, early diagnosis and risk stratification remain difficult, which hinders rapid and effective treatment initiation. Due to the heterogeneous nature of sepsis, potential therapy options should be adapted to the individual. Biomarkers like C-reactive protein and procalcitonin are routinely used as complementary tools in clinical decision-making. Beyond the acute phase proteins, a wide bunch of promising substances and non-laboratory tools with potential diagnostic and prognostic value is under intensive investigation. So far, clinical decision just based on biomarker assessment is not yet feasible. However, biomarkers should be considered as a complementary approach.

影响覆土和料层含水量的几个因素

食用菌 1984年第4期 47-48页

作者： peter p.Kalberer 蒋平

人工培育的双孢蘑菇(Agaricns bisporus)含有90％以上的水分。因此,水分管理非常重要。蘑菇培养料由包含有机养份的料层及覆土层组成。料层含水量达65～70％,覆土层的含水量为55～65％。

在断奶移进平坦地面猪舍约14日后,5—6周龄的仔猪往往会发生一种出血症,其死亡率可达10—20％。这些仔猪多半饲喂养猪场自己配制的饲料,虽然其中补充有大多数维生素,但实际上并不含有效的维生素k。此外,这些饲料还加有磺胺二甲嘧啶,众所周知这些药物会抑制维生素K的活性。注射维生素k或亚硫酸氢钠甲萘醌可以有效治疗这种病猪。实验表明,喂用加药饲料会导致疾病,而饲用不含磺胺二甲嘧啶的同样饲料却没有病症出现。实验结果可以推断,出血症是由以下三种因素的综合结果造成的,饲料中缺乏维生素k、饲料中含有维生素的拮抗物磺胺二甲嘧啶以及采用平坦地面猪舍饲养从而使仔猪不能从粪便或褥草中获得任何维生素k。
