In the new medical reform plan released in China last year, the policy basically revolves around electronic medical records, which also indicates that electronic medical records play an important role in the future development of the medical industry. How to use electronic medical records is more effective and has become Questions we have to think about.
At present, the hospital information system with electronic medical records as the core has attracted much attention. According to the requirements of the "Basic Standards for Electronic Medical Records (Trial)" issued by the Ministry of Health, the popularization and application of electronic medical records will certainly place higher demands on traditional storage systems.
Electronic medical records are personal medical and health records for life, requiring hospitals to establish corresponding electronic medical records systems and to be able to access the system anytime, anywhere. This means: Suppose someone has had hepatitis 10 years ago and has seen a doctor in the hospital, then when he comes to the hospital today to see liver disease, the doctor can immediately read the patient ’s medical record 10 years ago without waiting for half Hours or an hour or even longer.
Five challenges of hospital storage
Overall, the application dominated by electronic medical records is bringing five major challenges to hospital storage systems.
One is "saving". That is, the electronic medical record objectively requires a large increase in storage system capacity. Especially for large hospitals with overcrowded patients, the long-term preservation of the electronic medical records of all patients requires a considerable amount of information storage capacity.
The second is to "get out". That is to say, all kinds of information stored in the hospital must be able to be retrieved completely anytime, anywhere. And to ensure that all information is intact, it requires high reliability of the storage system. The problem of data loss or incompleteness cannot occur due to the long storage period.
The third is fast access. The electronic medical record system is a business system that supports the daily service operation of the hospital. The users are mainly doctors and nurses. Usually the business process of medical personnel is very tight, which requires that the data storage process related to the electronic medical record system must be fast and efficient. For example, when a doctor reads images on a computer, it is best to control the waiting time within a few seconds. If it takes a few minutes to adjust a film, the doctor will definitely be intolerable, and the application effect of the electronic medical record system will be greatly reduced. .
Fourth, the price is low. Due to the advancement of technology and the popularization of applications, the cost of various storage media is still decreasing. However, the pressure of electronic medical records on the rapid expansion of storage systems will inevitably lead to a rapid increase in the investment of hospital storage systems. The hospital's investment in storage is definitely to be controlled within its own tolerable range, and to highlight the cost advantage of storing medical records over paper media in the past.
Fifth, the cycle is long. According to the relevant administrative regulations of the health industry, the retention period of patient information should be long enough, at least for decades. According to the requirements of the residents' health records throughout the life cycle, some basic data are required to be kept for a longer period of time.
In recent years, storage technology has developed rapidly. With the development of technology, the information storage system of electronic medical records is also changing. For example, five years ago, storage methods were classified into emergency online, near-line, and offline. The storage system has three or four levels. At that time, offline storage also had to consider tape library and optical disk library; now, the storage system is basically one or two levels, and the storage method is usually online and near-line, and will not consider offline such as magnetic tape library or optical disk library. The way. Advances in technology have made online storage of disks possible.
The basic idea of ​​layered coping
According to the actual application situation of the hospital, we can divide the storage system into three levels: the bottom layer is the storage physical layer, that is, the disk array, such as: SAN array, NAS array, DAS array, etc.
The middle layer is the storage management layer, including storage management systems such as backup, migration, and virtualization. It is responsible for managing storage physical devices and building a storage system that is transparent to the application system.
The uppermost layer is the storage application layer, where the storage system is configured and used by the application system. For example: data backup can be implemented at the application layer, relying on the application layer software to back up the data.
The reason why the storage system is divided into three layers is to solve the challenges faced by hospital information storage from different levels. In other words, for the same type of challenge, we can consider comprehensive solutions from different levels. For example, the problem of data backup can be solved from the data management layer or the application layer. The capacity challenge can be solved by expanding the disks of the same array or by expanding different arrays. , And then start with the application layer configuration to solve, can also be solved in the management layer through cloud computing.
Now, the development trend of storage management is to gradually migrate some management functions from the upper layer to the bottom layer, so that various applications do not have to perceive the corresponding information storage details, such as how and where they are stored. In short, the above challenges can actually be solved from different levels.
