Description

Realize the electronic medical record system of inter-region medical data sharing
Technical field
The present invention relates to a kind of electronic health record EMR system that realizes the inter-region medical data sharing, belong to the medical information field.
Background technology
Country's electronic health record (and health account) system construction is the project of giving priority to that present developed country advances the health care informatization.Perfect electronic medical record system except that the level that can promote whole medical and health services, standard supervision, balance high-quality medical resource skewness, conveniently seek medical advice etc., also have a very important function, good individual medical data is shared can create very high economic worth.
General electronic medical record system construction scheme at present is difficult to really realize the target of national electronic health record (and health account) system construction.Perfect national electronic medical record system must possess three Core Features: data acquisition, data storage and safety, trans-regional convenient the sharing of data.The realization of electronic medical record system should be made of two parts: first be each independently unit (hospitals at different levels, basic unit, community sanitary mechanism) under the prerequisite of unified national disease (health and fitness information) data pattern and standard, realize data sharing function in the collection, safe storage, unit of medical data; Second portion is the convenient sharing functionality that realizes medical data between trans-regional each unit.It is to determine the national standard of electronic health record exploitation earlier that first realizes not having substantially more technical bottleneck, key; Next is when the overall software development of electronic health record design, the standard of the rationality that emphasis is noted designing, unitarity, distinct device data transformation interface.A lot of hospitals possess HIS, only need increase CIS, PACS, LIS system, at present new electronic medical record system exploitation is based under the standard card cage of U.S. HL7 more to be carried out, electronic medical record system after finishing realizes that data acquisition, the safe storage of separate unit inside do not have too many technical matters, in same separate unit LAN (Local Area Network), adopt 100M or above bandwidth, good system software design scheme, interface scheme, server and database scheme, realize the also not more difficulty of data sharing in the separate unit.There is technical bottleneck in the realization of second portion, and the medical data of electronic medical record system is shared design at present, is substantially to take to carry out the shared scheme that data interaction is transmitted, had access to by the central database of setting up different aspects.Concrete technological difficulties are: 1. the speed problem of data transmission.2. the real-time Transmission of data and regularly transmission problem.3. the management of vast capacity database and operation cost problem.4. the incomplete basic medical unit of population coverage rate maximum but basic hardware facility is realized the data sharing problem.5. data sharing problem when electric power and communication system fault.Be embodied in 1. outpatient services and see a doctor the matter of time of having access to individual medical data.If have access to patient data's time more than 5 minutes, will cause difficulty to outpatient service, produce data sharing and share bottleneck.Individual's medical data is different from other data, mainly is that data type complexity (medical data comprises literal, list, image, image data etc.), data volume are big.It is very normal that individual's medical data surpasses 100M, and the data information of a complete MRI just can surpass 100M usually, and the personal illness data are interrelated and increase progressively gradually in addition.Is 6.6 minutes in 2M private network mode in the theoretical value of transmitting a 100M data instance calculation of measured data transmission time with the city, is subjected to multiple factor affecting will be longer than the theoretical transmission time during actual transmissions; The data of transmission 500M are wanted 33 minutes in theory.2. central database construction and handling cost problem.Suppose that a city can provide the special line of unrestricted bandwidth to be used for the construction of electronic health record regional platform, realize the convenient transmission of medical data in network facilities support, under the prerequisite of sharing, medium-sized city contain have jurisdiction over the county population by 2,000,000 calculating, the construction of city level central database will very hugely (be announced 2008 Chinese hygiene industry statistics according to the Ministry of Public Health, do not contain village's clinic data, the outpatient service in 2008 of whole nation medical institutions is gone to a doctor and is add up to 35.32 hundred million person-times, add up to 11,483 ten thousand person-times in hospital), the mutual transmission workload of real time data also will be surprising, even if all can smooth implementation, the operation management cost also will be high surprising.Transmit alternately if can not realize real time data between hospital and the central database, still can't solve the regional interior convenient sharing problem of medical data, the inter-region medical data are convenient shared than convenient shared more difficult in the zone.3. the medical data sharing problem of basic medical unit.The 5th Chinese population reconnaissance information (2000), China's Mainland population 12.658 hundred million, agricultural population is several 8.739 hundred million, accounts for 63.91% of total population, town's level population 1.66 hundred million, urban population 2.926 hundred million.Statistical data shows: most crowds are distributed in medical treatment and the backward following rural area, county of basic communications service.Most places are difficult to set up good secure data storage, transmission system in long-time.4. the burst thing causes the data sharing obstacle.Power failure, communication operator system fault, network backbone fault, hospital database fault or the like take place as zone, down town database area.The confusion that above-mentioned situation will cause overlay area hospital curative activity appears.
The many countries in the whole world or have actively pushed forward the exploitation and the construction of electronic medical record system.Find that U.S.'s electronic health record (health account) system construction at present meets with mortality bottleneck---the storage security and the data transmission problems of individual medical science (health/disease information) data after the present situation of research U.S. electronic medical record system.The research and development of U.S.'s electronic medical record system start early, the infusion of financial resources amount is big, technology maturity is high, has set up unique " electronic health record " national standard-HL7 in the present whole world.The most successful the earliest state of Indiana of electronic health record exploitation, the whole America, existing 30 years history, the maximum technical barrier that faces at present is data sharing.Permanent (Kaiser Permanente) annual turnover of Kai Ze is 34,000,000,000 dollars, has to surpass 8,000,000 patients and the largest electron medical treatment project of entire United States, and it is more than half that they invest 10 yearly plan times of 4,500,000,000 dollars; At present still can't fine breakthrough data security and the technology barrier of sharing.Twice pair of big power failure of whole web influence of the said firm's encountered is autumn in 2005 for the first time, and occurring in is the eastern bank data center of 4 area services.The power failure that another time occurs in California data center in 2006 has then influenced the area, west bank.Can't visit any computer record in lasting 16 to 30 hours, at medical field, in case such problem occurs as being both a bad dream.The research and development of U.S.'s electronic medical record system mainly are in a kind of in a dilemma difficult situation because of being difficult to break through the convenient share technique difficult problem of individual medical data at present.The construction of China national electronic medical record system has just started but the symptom of a trend of similar U.S. problem occurred, and China should receive U.S.'s successful experience, avoids simultaneously following the track of the overturned cart.
