Assessment process helps hospitals determine what's wrong and what's to be done about it

When costs overwhelm revenues in a particular service or program, it's time to stop and get a handle on what's gone wrong. Maybe the program idea is still good but needs a course correction or two. Maybe it was a bad idea all along, or it's become a loser because of new market forces. Getting at the problem requires a systematic approach, according to Sally Berger and Sandra Wisener of Ernst and Young.     

积极推进药品集中招标采购切实减轻群众药品费用负担

为提高医院药品采购透明度,纪正药品购销中的不正之风,保证药品质量,降低药品采购价格,减轻群众不合理负担,我省自1999年12月起,开展了药品集中招标采购改革,一年来, 完成了三次药品集中招标采购。由第一次招标采购时仅为省人民医院1家,扩大到现在的12家医院,三次招标,共采购药品319种,采购金额共计5300万元,目前正在开展第四次药品集中招标采购,参加招标的医疗机构扩大到县及县以上公立综合性医院,专科医院,中医院和妇幼保健院（所、站）,招标药品700多种,采购金额约8000万元。     

A risk-benefit analysis approach to seafood intake to determine optimal consumption

Seafood provides n-3 long-chain PUFA (n-3 LC-PUFA), vitamins and minerals, which are essential to maintain good health. Moreover, seafood is a source of contaminants such as methylmercury, arsenic and persistent organic pollutants that may affect health. The aim of the present study was to determine in what quantities seafood consumption would provide nutritional benefits, while minimising the risks linked to food contaminants. Seafood was grouped into clusters using a hierarchical cluster analysis. Those nutrients and contaminants were selected for which it is known that seafood is a major source. The risk-benefit analysis consisted in using an optimisation model with constraints to calculate optimum seafood cluster consumption levels. The goal was to optimise nutrient intakes as well as to limit contaminant exposure with the condition being to attain recommended nutritional intakes without exceeding tolerable upper intakes for contaminants and nutrients, while taking into account background intakes. An optimum consumption level was calculated for adults that minimises inorganic arsenic exposure and increases vitamin D intake in the general population. This consumption level guarantees that the consumer reaches the recommended intake for n-3 LC-PUFA, Se and I, while remaining below the tolerable upper intakes for methylmercury, Cd, dioxins, polychlorobiphenyls, Zn, Ca and Cu. This consumption level, which is approximately 200 g/week of certain fatty fish species and approximately 50 g/week of lean fish, molluscs and crustaceans, has to be considered in order to determine food consumption recommendations in a public health perspective.     

药品招标采购“闵行”模式推广的可行性和策略分析

介绍上海市闵行区医疗机构药品招标采购模式的基本情况,分析"闵行模式"下的利益格局调整。并按照政策可行性评估的基本框架,探索"闵行模式"推广的可行性以及可能引发的问题。结果表明,在行政层面,推广"闵行模式"所面临的问题主要源自于政府的决策意志和执政能力;在经济层面,主要是当地物流和信息产业发展程度等影响该模式的实施。在进一步分析按不同行政区域推行该模式可能遇到的问题的基础上,本研究得出"闵行模式"在实践上具有推广的价值基础,在政治、经济、行政、技术、伦理等理论层面具有推广的可行性,尤其在地市行政区域内推广应用可行性较高的结论。

Trace analysis to determine heavy metal load in lung tissue

Summary A routine method to determine the presence of partly environmentally relevant trace elements Al, Be, Cd, Co, Cr, Cu, Fe, Mn, Ni and Pb in lung tissue is described. The stages of process are preparation of samples conforming to the analysis material, decomposition, and subsequent trace determination by atomic absorption spectrometry. The results obtained from 125 samples show that chemical analysis is an effective aid in identifying and substantiating occupational risks.
