好医院是由医生领导?

在欧美的趋势是医院公司化,领导职业经理人化(没有医学相关学位的人领导)。国内离这一步还差远吧,医生联盟统治的医院几乎是滴水不漏的。现在有文章检验欧美的趋势,但是结论离因果效应还差得远吧。

Top-performing hospitals are typically ones headed by a medical doctor rather than a manager. That is the finding from a new study of what makes a good hospital.
Its conclusions run counter to a modern trend across the western world to put generally trained managers — not those with a medical degree — at the helm of hospitals. This trend has been questioned, particularly by the Darzi Report, which was commissioned by the U.K. National Health Service, but until now there has been no clear evidence.
Amanda Goodall PhD, at the Institute for the Study of Labor (IZA) in Bonn, Germany, constructed a detailed database on 300 of the most prominent hospitals in the United States. She then traced the professional background and personal history of each leader. The research focused particularly on hospital performance in the fields of cancer, digestive disorders and heart surgery.
The study shows that hospital quality scores are approximately 25% higher in physician-run hospitals than in the average hospital.
Goodall stressed that more research would be needed before cause-and-effect could be truly understood. The study, a cross-sectional one, uses data from 2009. "This is an intriguing pattern but these snap-shot results for a single point in time do not prove that doctors make the best heads of hospitals, although they are consistent with that claim. More research following a range of hospitals through time is urgently needed," she said.

"Physician-Leaders and Hospital Performance: Is There an Association?", by Amanda H. Goodall, is in press at Social Science and Medicine. It can be downloaded free of charge as from the IZA website (www.iza.org) as IZA Discussion Paper No. 5830:http://ftp.iza.org/dp5830.pdf

Barack Obama


I
n 2008, Barack Obama wins a smashing electoral victory, largely because the public believes he's a calm, cool adult who can lead the country out of an economic crisis. But for some crazy reason, he decides to focus much of his attention on passing a universal health care plan that has been the long-term dream of his party. This, despite polls that indicate nearly 80% of the public are satisfied with the health care they already have. The plan passes, but it's so complicated, the public isn't sure what's in it (and is wondering why the President hasn't focused similar attention on the economy), and Obama's party is clobbered in the 2010 elections.

Small-Area Analysis(小地域分析)

Small-Area Analysis:

A method of analyzing the variation in utilization of health care in small geographic or demographic areas. It often studies, for example, the usage rates for a given service or procedure in several small areas, documenting the variation among the areas. By comparing high- and low-use areas, the analysis attempts to determine whether there is a pattern to such use and to identify variables that are associated with and contribute to the variation.

Synonym: small-area variation analysis, small-area variations, small-area variation, small-area study.

范畴经济 VS. 规模经济

economies of scope --范畴经济 or 范围经济,又可叫做"外部规模经济"(External Economy of Scale

见:互动百科 wiki-MBA

定义:因同时生产(经营)几种相关的产品或服务而引起的经济效益提高。 透过营运范畴的扩大,两个以上的事业单位共同分担研发、营销、生产等成本,而享有的经济效益,使总成本下降。

 

单一厂商同时生产两项以上物品和服务的成本比分别由专业厂商生产的成本更低廉导致厂商生产出现范畴经济的原因,可能是来自多元化的经营策略、营运范畴的扩大、资源的分享、投入要素的共同、统一管理的效率、财务会计的优势,导致生产成本降低的效果规模经济是相对于专业化而言,范畴经济则是相对于多元化而言,两者并没有直接的关联

范畴经济也就是多样化经济,即企业在生产不同的产品时,若出现成本递减的现象,则就可称之为范畴经济。

 

(1)    q1q2代表同产C(q1+ q2) < C(q1) + C(q2)表示联合生产的总成本小于分别生产的成本总和,亦即存在「规模经济」。

(2)    q1q2代表同产品,C(q1+ q2) < C(q1) + C(q2)表示不同产品"一起"生产的总成本低于分别生产的成本总和,亦即存在「范畴经济」。
