罗切斯特的经济学教授Steven E. Landsburg写道：如果你不能改变一个人的消费，你就不可能对这个人收税，即便你把他银行里的钱都拿走也不行。郭凯：steven不过是说税收负担最终未必落在那个交税的人头上。我想起这大概就是所谓的"富人税（奢侈品税啊，房屋买卖课税啊~~~list~）"为什么总是伤害穷人的理论。
In this stupid country, we have enough physician, sufficient pharmacuticals and devices, but we don't have ownership, so the health system is a mess. It is growing, but it can not be evolving, re-organizing, or even moving. The system is learning, yet without development. All of these resulted from the idea that no one knows who owns it. 租值消散（dissipation of rent）或租值耗散理论(The Theory of Rent Dissipation)在国内译作"租值耗散"，又称"租耗"。 -- 公地的悲剧，产权的经济学。

US physicians urge end to unnecessary stent operations, 冠心病支架手术的滥用已经将许多本来病情稳定的患者置于并发症风险之下，2008年有个美国Maryland州的医生Mark Midei因为一天做了30例支架手术被吊销医师执照，医生跟制售垃圾食品的supplier真是没啥区别。

[zt] Aid.vs.Trade
美欧的aid不能转变非洲社会，但是中非的贸易trade却能塑造shape一个新的非洲。en ~~ maybe a new idea
But aid from the outside cannot transform whole societies, whole countries. That can only come about through producing things and trading them or doing something someone else wants to pay for. Ironically, it is the capitalist West that still sees Africa as a continent that needs aid, while Communist and former Socialist governments like China and India see it as a business opportunity.

一个HRH和health outcome的RCT--perfect！
从Prof Grepin推荐的best 10中发现一个Pakistan做的聚簇RC Trial试验，看好研究真是过瘾。在给这篇文章的correspondence里，Davis引用UNICEF的数据"In the developing world, 440 of 100,000 births result in maternal death, as compared with 12 of 100,000 in the developed world."，可见这里面还有很多工作可以做。但是话说回来，本文的RCT结果显示的是纳入传统的接生员只对Prenatal mortality有作用，对maternal mortality没有显著效果。

hospitalist II
--------DMH Hospitalist program 说明--------
Hospitalists are fully trained Internal Medicine physicians who devote all their clinical time to the care of hospitalized patients. They serve as attending physicians for patients who are directed to inpatient care by their primary care physician.
A model for hospital care in Europe for half a century, Hospitalists are also represented some of the United States leading hospitals
Hospitalist focus on patient care, comfort
A full-time hospital-based physician has distinct benefits. For example, a Hospitalist has the ability to rapidly coordinate inpatient care and react in real-time throughout the day to clinical data and changes in a patient's medical status.
At each step, whether ordering treatments, test, or consult with specialists when appropriate, communication between the Hospitalist and your primary care physician is seamless.
Hospitalists are also available consistently throughout a patient's stay to answer questions, discuss test results and provide reassurance. The Hospitalists also are familiar with hospital staff and the latest technologies available at hospital.
