The research and analysis of big data storage under the Hadoop platform needs to complete the loading of virtual machines, the installation of Hadoop and platform construction, the application of some file management instructions of HDFS and the problems of Hadoop storage. The first thing to solve is the installation of Linux. I have consulted a lot of materials and articles. I have experienced many failures, and I have slowly understood many problems that I have not succeeded in. Finally, I have an idea of installing a virtual machine system. CentOS7.0 was successfully installed and its basic configuration and installation of some basic tools were completed. The high efficiency of Hadoop-based secure medical big data ecosystem is determined by its own characteristics—fast information transmission, transparent information and information. Because information reduces transaction costs, coordinated costs, and execution transaction costs, it increases transaction efficiency and increases patient value. Improving the efficiency of medical business is one of the important goals of medical digitalization. With the help of electronic information mobilization means and information mode, such as automatic medicine dispensing machines and logistics lines created by modern information technology, medical services such as automatic medicine dispensing machines and logistics lines can be used. Rapidly improve medical efficiency and make labor-intensive business transition to high efficiency and precision. The increase in transaction efficiency leads to a reduction in costs and thus more value. At the same time, more information or improved information reduces the cost of seeking medical consultations for patients. Through the remote video clinic of the upper hospital and the logistics distribution of the medical platform, third-party payment and other background management, patients can find superiors in the nearest community hospital. Hospital doctors have simplified medical procedures, effectively reduced health care costs, saved time and reduced medical costs. Figure 9 shows the Test result between Hadoop and traditional method.
China has not formed an effective technology construction mode and business operation mode in the construction of information platform services. In terms of technology, standardization management of information has high requirements for information transmission standards and exchange standards, and the state has no system. Advance standards, comprehensive evaluation of system platform construction, including supervision and evaluation of institutions, stay in the line and framework stage; in the service operation, there is a lack of completed and mature standardized management system, and no effective service model is formed. . The Safety Medical Big Data Ecosystem is an information platform for all medical and health departments in the society. It involves the special group of the elderly, the health administrative department, the medical service organization, the disease prevention, and control centre, the social medical security and other related departments. Multi-sectoral integration and the management of the elderly in China is still multi-sectoral management, the government functions are not clear, resulting in uneven pension services, unbalanced demand for old-age care, and low resource utilization, which seriously affects the development of services for the elderly. The government is required to form a complete and mature standardized management mechanism and manage it in an integrated manner to integrate health care resources.Figure 10 shows the test results of packet loss rate errors in secure medical big data transmission.
Medical expenses are the largest expenditure in addition to basic living. China's medical insurance is limited to a single business operation, and residents' medical insurance has not yet involved regional collaborative services. The medical care system has not yet established, and the medical insurance costs for inter-patient diagnosis cannot have settled. Many local telemedicine services are not included in the scope of medical insurance reimbursement. Therefore, the elderly are more willing to go to the first-level hospital or the secondary hospital to set up a medical insurance hospital for treatment.
The development of informatization in China has only begun in recent years. There is a serious information bias. In the city and large hospitals, there is still an initial construction of informatization, and the level of informatization of grassroots health institutions is not widely applied, resulting in the inversion of the hierarchical structure. It is because the awareness of informatization construction of grassroots health institutions is weak, and the lack of introduction of information zed talents is lacking. Secondly, the level of informatization application is low. The health Informaionization construction of primary medical institutions has not yet covered comprehensively. The treatment of basic diseases has not involved informatization. Informatization applications are still at a lower level, lacking the collection and accuracy of data, leading to the informatization construction in the community.Figure 11 shows the comparison result of safe medical big data data transmission performance.
In the development of the safety medical big data ecosystem, the role of government departments is the most critical, and it is the main bearer of medical services. Therefore, the government must scientifically develop the old-age service system, conscientiously implement the multi-level and diversified service needs of the elderly, and adhere to the development of China's elderly services in the direction of intelligence and information. The health management department should avoid the information system project in the construction process, because the standards are inconsistent, which are leading to the original intention of leaving the design, meaningless waste of the sword. At the same time, the government should give full play to the guiding role and break the Informa ionization of medical resources. In addition to the horizontal management of health services, it pays attention to the vertical management of health services, coordinates the interests of various departments, and cooperates regionally to form a scientific system. Integrate more old-age resources, strengthen overall coordination, study and formulate a unified, specific and standardized elderly care service process, give full play to the government's binding role, and establish a benign interaction mechanism between government, society and market. The design and grassroots advancement have combined at the same time, and the government should form a unified payment system and provide financial support for the aged care service.
Because of the weakening of physical function, the elderly have a high incidence of illness in the elderly, frequent frequency of medical treatment, medical expenses have characterized by “rigid” rise, and the burden of medical expenses is heavy. The government should adjust the medical insurance policy and increase the expenditure on medical insurance for the elderly . The government should also encourage the development of medical commercial insurance, guide residents to make more scientific and rational medical financial planning, broaden the source of medical insurance funds for the whole society, and mobilize social resources.
Whether it is a traditional nursing home that has already started operating in the early days, or a large capital force that is planning to build an industrial platform, they are in urgent need of a comprehensive and efficient information system. Primary medical institutions are the health institutions closest to the elderly. The informationization of grassroots medical institutions directly affects the amount of medical data provided by the health care big data ecosystem. Therefore, it is recommended to increase capital investment in grassroots medical institutions, strengthen information construction, and introduce informationization.
The advantages of the medical information health platform should have popularized for the elderly, and the elderly can experience the convenient service brought by the medical information platform. The elderly can understand their physiological parameters at home and operate easily. Through platform remote consultation, the space distance is greatly shortened, online consultation and diagnosis services for elderly people and doctors have provided, and the self-health management of the elderly, especially elderly patients with chronic diseases, and the transition from public management to personal management are guaranteed to a certain extent. The efficient service quality of the elderly and the improvement of the satisfaction and participation of the elderly in medical treatment can stimulate the enthusiasm of the elderly to use the platform.
