In the new medical reform program released last year in China, the policies basically revolved around the electronic medical record. This also marks that the electronic medical record plays an important role in the future development of the medical industry. How to apply the electronic medical record is more effective. The question we have to think about.
At present, hospital information systems with electronic medical records as the core have attracted much attention. According to the requirements of the "Basic Standards for Electronic Medical Records (Trial)" issued by the Ministry of Health, the promotion and application of electronic medical records will inevitably put forward higher demand for traditional storage systems.
An electronic medical record is a personal medical and health record for a lifetime, requiring the hospital to establish an electronic medical record system that is appropriate and accessible to the system anytime, anywhere. This means: Suppose a person has had hepatitis 10 years ago and has seen a disease in a hospital. When he comes to the hospital today to see a liver disease, the doctor can immediately access the patient's medical record 10 years ago without waiting for half. Hours or an hour or even longer.
Five major challenges in hospital storageIn general, applications dominated by electronic medical records are bringing five major challenges to hospital storage systems.
The first is "save it." That is, the electronic medical record objectively requires a significant increase in the capacity of the storage system. Especially for large hospitals where patients are overcrowded, the electronic medical records of all patients have to be preserved for a long time, and the demand for information storage capacity is very considerable.
The second is "getting out." That is, all kinds of information stored in the hospital can be completely taken out at any time and anywhere. To ensure that all information is intact, the storage system is required to have high reliability. It cannot be caused by data loss or incompleteness due to the long storage period.
Third, the access speed is fast. The electronic medical record system is a business system that supports the daily service operations of the hospital. The users are mainly doctors and nurses. Often the medical staff's business processes are very tight, which requires that the data storage process associated with the electronic medical record system must be fast and efficient. For example, when a doctor views an image on a computer, it is best to keep the waiting time within a few seconds. If a film is to be waited for a few minutes, the doctor will certainly 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 popularity of applications, the cost of various storage media is still decreasing. However, the rapid increase of pressure on the storage system by electronic medical records will inevitably lead to a rapid increase in investment in hospital storage systems. The hospital's investment in storage must be controlled within its own affordable range, and it must highlight the cost advantage of storing medical records compared to previous paper media.
Fifth, the cycle is long. According to the relevant administrative regulations of the health industry, the period of retention of patient information and information should be long enough for at least several decades. According to the requirements of the residents' health records throughout the life cycle, some basic data requirements are kept for a longer period of time.
In recent years, the development of storage technology has changed rapidly. The development of technology has also changed the information storage system of electronic medical records. For example, five years ago, the storage method was divided into emergency online, near-line, offline, etc. The storage system has three or four levels. At that time, offline storage also considered the way of 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 tape library or CD-ROM library. The way. Advances in technology have made disk online storage possible.
According to the actual application 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, and so on.
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 top layer is the storage application layer, which is configured and used by the application system. For example, data backup can be implemented at the application layer, relying on software at the application layer to back up 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 integrated solutions at different levels. For example, for the problem of data backup, it can be solved from the data management layer or from the application layer; for the capacity challenge, it can be solved by expanding the disk of the same array, or by expanding different arrays. Then, it can be solved from the application layer configuration, and it can also be solved by the management through cloud computing.
Nowadays, the trend of storage management development is to gradually transfer some management functions from the upper layer to the bottom layer, so that various applications do not need to perceive the corresponding information storage details, such as how to store and where to store them. In short, the above challenges can be solved at different levels.
