Ouke cloud Chain Research Institute: application of blockchain in the medical industry

Time : 12/05/2022 Author : yolk9c Click : + -
        In recent years, blockchain, as a disruptive cutting-edge technology, has collided with many traditional industries under the popularity of the market, creating application cases of blockchain empowerment. Blockchain technology has the characteristics of distributed storage, non tampering, transparent and traceable data. It can naturally solve the pain points of many industries, such as information asymmetry, trust problems, information islands, etc., so it is widely used in finance, supply chain, intellectual property, insurance, medical and other fields. The medical industry can be described as a social rigid demand, and with the aging of the population and the improvement of people's health awareness, the demand for medical treatment continues to expand. At the same time, the difficulty of seeing a doctor has troubled many people, so the rational allocation and effective utilization of medical resources has become the primary problem.
 
        Specifically, from the perspective of demand, population size and population structure are the direct factors affecting demand. According to the National Bureau of statistics, China's total population has reached 1.4 billion by the end of 2019. At the same time, the population over 65 years old accounts for 12.57%, accounting for 180million people, and this number will increase year by year. In the past three years, the annual compound growth rate of the population over 65 years old has reached 5.45%. The ability and willingness to seek medical treatment are also factors affecting demand. In recent years, people's living standards have improved, and their health awareness has been continuously enhanced. China's urbanization rate has steadily increased, reaching 60.60%, and has increased by an average of 1.04% per year in recent three years.
 
        In terms of supply, the absolute scale of the medical industry is increasing year by year, but the per capita resources are still insufficient. As of June 2020, the number of tertiary hospitals, secondary hospitals and primary hospitals in China is 2831, 9901 and 11400 respectively. The cumulative number of diagnosis and treatment in the first half of 2020 is 13.6, and the number of diagnosis and treatment per capita is less than 1. In addition, the allocation and utilization of medical resources need to be improved. The segmentation fields such as pharmaceutical marketing and product circulation are relatively traditional, and new technologies such as blockchain, big data and artificial intelligence are urgently needed. Recently, the National Health Commission and other official institutions have recognized the importance of blockchain and advocated the integrated application of blockchain and the medical and health industry. Sichuan Province has established a working group on the preparation of blockchain medical and health application specifications, and has successfully held its first working meeting.
 
        It is proposed to "explore and study the application scenarios of blockchain in the medical and health field, accelerate the research and formulation of blockchain information service standards in the medical and health field, and strengthen the standardization and guidance of the integrated application of blockchain technology and the medical and health industry". propose "Relying on the national integrated online government service platform, the National Medical Insurance Bureau will actively communicate with relevant departments, establish an inter departmental information exchange mechanism to realize the sharing and collaboration of medical, pharmaceutical and medical insurance data, and actively explore the application of blockchain technology in medical insurance related fields. It is proposed to strengthen data sharing and explore the construction of a patient led medical data sharing mechanism, which should Use blockchain and other technologies to achieve secure flow and authorized access.
 
        In terms of health, it said that it would explore and create blockchain technology application scenarios around the construction needs of medical and health management system with data security, reliable process and regulatory compliance; Based on the characteristics of blockchain technology, such as data sharing, information transparency, intelligence and credibility, explore its application in medical supervision, vaccine management, medical waste management and other business scenarios. Blockchain technology can help solve the pain points of the medical industry. The following combs out the main pain points of the medical industry and the key points of blockchain technology enabling the medical industry:. L medical information disclosure: personal medical data is very private and important. According to Tencent smart security, medical information on the black market of the Internet in the United States is 10 times that of credit card information.
 
        However, the valuable data of the medical industry has internal and external problems: bad people covet it internally and hackers covet it externally. According to the 2017-2018 China Hospital Informatization survey report released by the information management professional committee of China Hospital Association (Chima), the 484 independent hospitals interviewed are facing the risk of information disclosure to varying degrees. There have been many medical information leaks across the country. In September 2017, the Legal Daily reported that the service information system of a hospital was hacked, resulting in the information leakage of 700million citizens. In September 2018, the Economic Daily reported that among the top three hospitals in China, 247 hospitals had detected extortion viruses.
 
        The encryption algorithm in the blockchain can effectively protect patients' privacy. Even if it is leaked, bad people or hackers get encrypted anonymous information, which will not pose a threat to patients' privacy;.

L data island: the medical system is complex and the degree of information sharing between different systems or institutions is low. In addition, the degree of information sharing between the medical industry and downstream insurance industry is not enough. Blockchain can electronize and store relevant data on the chain, realize distributed data sharing, and break the barriers between different systems or institutions;.
 
        L fake drugs and inferior drugs: fake or inferior drugs and equipment will do great harm to patients, and will also undermine people's confidence in medical institutions. The most famous case is the forgery of 2018 Changsheng biological vaccine, and blockchain technology can support anti-counterfeiting and traceability, and the data of drugs or equipment from R & D to production and circulation are fully transparent. Even if human factors are found to be fake, it is also convenient to hold accountable, and to a certain extent, curb the manufacturing of fake behavior. According to the links of medical services, the medical field is divided into the research and development, pricing and sales of products, and the treatment and insurance of users. The problems existing in each link and the solutions of blockchain are described respectively. (1) In terms of research and development, blockchain is conducive to data sharing, preventing the falsification of clinical trial data, and the sharing of valuable scientific research data can promote the common progress of the industry;.
 
        (2) Some drugs, especially innovative drugs, are very expensive and expensive. By linking the cost data of all links, it is conducive to open and transparent price details and curb the behavior of asking for prices;. (3) The medical industry system is complex, the industry concentration is low, and there are many scattered small enterprises, resulting in low data transparency. At the same time, many fake and shoddy products have been bred. The data transparency and anti-counterfeiting traceability functions of blockchain can be applied to the case;. (4) The information sharing between traditional Chinese medicine hospitals and hospitals in the traditional medical system is low, and patients often face the dilemma of duplicate examination items during Cross hospital treatment. Using blockchain shared data can realize the seamless connection of information during Cross hospital treatment.
 
        In addition, patients' feedback information is often not used effectively. The existing medical system does not fully collect patients' rehabilitation after treatment. Drug research and development only focuses on clinical data and early use. A large number of patients' use information has not been collected or used. The combination of blockchain and big data can achieve high touch and effective feedback of patient information, and pay more attention to patient-centered; In terms of anti-corruption, there are mainly bad behaviors such as medical insurance premiums, rebates, bribery, etc. by prohibiting offline money transactions and the complete uplink of medical information, the above bad behaviors can be technically suppressed;. (5) The downstream of the medical industry is insurance and other fields, which have complex processes and lack of trust.
 
        When applying for medical insurance, many documents are required and there is insurance fraud. The information of medical and related insurance is linked through blockchain, supplemented by smart contracts to realize automatic claim settlement, which can effectively solve the trust crisis and avoid complex processes. A major application of blockchain medicine is data sharing, but the benefit balancing and game of stakeholders may hinder the implementation process of the application. For example, the experimental data in the research and development stage may leak the research and development progress, and may be used by others to make achievements first. Therefore, it is suggested that the research and development data should be delayed. For example, the data should be linked after the success of research and development, which not only realizes the openness and transparency of clinical trial data, but also protects intellectual property rights.
 
        Data sharing across hospitals, hospitals and downstream medical insurance involves multiple institutions, which may require blockchain projects from top to bottom or multi-party cooperation. It can be found that practical applications cannot be achieved without the organic combination of blockchain, smart contracts, big data and other technologies, and can not be achieved by blockchain alone. At the same time, blockchain technology is not omnipotent, such as anti-corruption, anti-counterfeiting, etc. in addition to the reform of blockchain technology, it also requires offline human efforts, electronic processes, ensuring the integrity of information on the chain, and eliminating offline private handover. Take the lead in realizing the opening of the electronic Department of medical institutions to social retail pharmacies, realizing the mutual sharing and exchange of medical dispensing information throughout the process, and the whole network payment, and building a diversified drug purchase supervision platform among patients, doctors, pharmacists and supervisors.
 
        We are committed to relying on technology to break the current chronic diseases of the medical beauty industry, deeply integrate medical beauty and derivative industry resources, build a medical beauty industry application system in the value Internet era, and open up a value Internet niche belonging to the medical beauty industry. Pulcher ecosystem includes a basic public chain designed for the medical beauty industry, a set of distributed application systems and a series of support structures, which can provide functional support and pass economic ties for various participants in the medical beauty industry and related industries, and serve the comprehensive upgrading and transformation of the medical beauty industry. Through the up chain of practitioner qualification, patient history, postoperative effect, dispute arbitration and other links, provide tamper proof record information, so that the industry can develop more healthily.
 
        Promote data standardization, semantic standardization and clinical process standardization. Here, the basic idea of open source, openness and sharing is very important, which is the underlying logic of data interconnection. It aims to create a blockchain tool to manage the drug supply chain, so that pharmaceutical manufacturers, wholesalers, hospitals and other relevant institutions can use blockchain to register all drug-related information and ensure its traceability to the greatest extent. It aims to cooperate with the pharmaceutical industry, small and medium-sized enterprises, universities, clinical laboratories, hospitals, patient representatives, etc. to use blockchain technology to improve medical services and explore the wide application of blockchain in the fields of fake drug detection, supply chain, patient data and clinical trials.
 
        The pharmaceutical management service platform jointly built by Suzhou mobile and Kunshan Health Commission has been successfully launched, and it is a top-down project representative. Blockchain technology encrypts patients' diagnosis and treatment information to protect patients' privacy. At the same time, data security and credibility enable hospitals to seamlessly share information without worrying about data security. Mediledger is a typical project jointly developed by multiple institutions. The participants include Pfizer, chronicled, mckessoncorp, etc. the project is still under development, mainly to solve the problem of data sharing, and uses a smart contract to automatically perform reconciliation, refund and other processes.
 
        From the current blockchain medical projects, we can find that most of the projects focus on data sharing and anti-counterfeiting traceability, and data sharing is the application aspect mentioned most in the official documents. More top-down or multi agency cooperation methods are used. As mentioned above, cross agency data sharing involves multi-party interest games. The top-down method is conducive to the rapid and stable advancement of the project, and the multi-party strategic cooperation of large institutions is convenient to reach a consensus. With the aging of the population, the urbanization rate, and the improvement of people's ability and willingness to see a doctor, the demand for medical treatment is increasing, but the per capita supply resources of medical treatment are limited. In this context, the effective allocation and full utilization of medical resources is particularly critical.
 
        Blockchain can solve the problems in research and development, pricing, sales, patient treatment, insurance and other links, and help achieve data sharing, transparency and credibility, anti-counterfeit traceability and other functions. Whether it is official documents or application status, breaking down inter agency barriers and realizing data sharing are major issues, and the main methods are top-down and multi-party cooperation. Blockchain should also play a role in combination with smart contracts, big data, etc. at the same time, it is also noted that blockchain is not omnipotent. In addition to the technical level, the solution of some pain points needs to rely on the efforts of other aspects, such as artificially ensuring the integrity of data on the chain, ensuring that there is no offline private connection, etc.
