Liu Haozhe: The construction of health information platform in large data age

After nearly 20 years of development, China http://www.aliyun.com/zixun/aggregation/14059.html "> Medical information has a more obvious development, large and medium-sized hospitals have basically completed the construction of network architecture." However, there is still a large gap between the delivery of information from residents and nurses to the bedside of patients. It technology has been recognized as an important tool to promote medical informatization. On the 2012 Dell Storage Forum, the reporter interviewed the information director of Zhangjiagang Health Bureau, who walked in the front of medical informatization, and discussed the topic of "How to use information technology to build a regional health platform" in the era of Zhang Haojie.

Zhangjiagang is a more famous city, but to ask what the specific provinces and cities, it is estimated to be baffled a group of people, in fact, Zhangjiagang is a county of Suzhou, located in the Yangtze River and coastal two economic interchange. According to director Liu, Zhangjiagang resident population is 900,000, the permanent population is 1.2 million.

At present, Zhangjiagang medical institutions have a total of 8 municipal health units, 7 public hospitals, 27 private hospitals, 8 community health Centers, 231 community health stations, and a total of 5615 open beds, the city's health system staff is 8249 people, the medical staff is more than 6,000 people.

Stark contrast: resource-limited storage demand is exploding

"The data center of the Zhangjiagang Health Bureau and all the medical institutions affiliated to it have been networked, and the number of computers actually connected to more than 4,000 units." "On these computers, we are able to access the health files across the organization and across the department through our special network," said director Liu. Terminal data can be transmitted through the data transmission line to the data center in Zhangjiagang, including the doctor's computer and nurses on the computer generated data, medical diagnosis data, examination data. ”

It is reported that the Zhangjiagang data center stores 1.25 million of the files of the resident population, while returning 1.25 million people to the permanent population have established a health file, Liu said this has far exceeded the national Ministry of Health to establish file requirements. At the same time, the establishment of dynamic resident electronic health files 119, of which the special archives of chronic diseases is 180,000, which also established 380,000 archives of the elderly and 120,000 elderly medical records, 700,000 women's basic files and 160,000 diseases census files.

Such a huge demand for data storage, but director Liu said there are only three people to manage these data, the limited human resources and storage demand for the sharp contrast, then Liu director how to build a regional information platform?

How to build information platform: hardware + Software

These data for hospitals and patients, are particularly important significance, only the management of data, the use of good data to reflect the value, and the first problem of managing the data is how to support such a large amount of data parallel? Director Liu separately from the hardware and software two angles for us to analyze.

* Hardware: Take full advantage of virtualization technology

Director Liu believes that hardware selection must choose their own appropriate, do not blindly pursue the brand and other factors, according to the demand, Zhangjiagang data center to select all of the PC server, the physical server has 22, Liu Director of which 16 have been virtualized. According to its introduction, the virtual server running close to 300, including production environment, test environment and development environment. So far, the main database server in Zhangjiagang has been virtualized, "there are still some concerns, but from the effect of the operation, it is able to support the volume of data such as our operation." Director Liu introduced the road.

It is reported that all the storage structure of Zhangjiagang data center is based on Dell's EqualLogic, there are currently 9 equallogic, there are some original legacy of optical storage. 20 hospitals have deployed data to the front switch, the front switch physical machine is 20 units, each machine is based on the proportion of 1 per cent of the virtualization, that is, 20 hospitals each deployed a physical machine, each physical machine run three virtual servers, respectively, providing video, ECG and diagnosis and treatment of timely transmission of data. Director Liu said that for the data that does not need real-time transmission, the function is divided by the way of virtualization.
