If we talk about seniority, microbes must be the oldest species on earth, and the scary virus is a kind of microbe that was born almost at the same time as the earth and has existed for four billion years.
The emergence of viruses will never let us know how close humans are to a major biological disaster, just like this "Wuhan Epidemic" came silently.
When people face public health emergencies, how to effectively control the disease prevention and epidemic prevention system, emergency system, logistics system, etc. is very crucial.
Disease prevention and control is a systematic project of the whole society, and the monitoring and prevention of information technology cannot be ignored. So what inspiration can the ascending blockchain technology bring to virus prevention and control?
Blockchain helps improve disease prevention and control
Quick response
At present, the blockchain has many application scenarios in the field of medical and health applications, including patient identity authentication, electronic cases, clinical research and development, drug traceability, medical insurance claims, disease prevention and control, etc.
Among them, the disease prevention and control technology based on blockchain involves administrative supervision and other issues. The industry has certain specificities, and there are few cases and studies in China.
However, internationally, the research and application of blockchain in the field of disease prevention and control is very active. On the US medical online library website, searching with "blockchain" as a keyword, you will find a total of 376 high-quality medical blocks Chain papers.
In 2018, agencies such as the US Centers for Disease Control (CDC) and the Global Health and Safety Association (GHSA) also proposed verifiable blockchains to respond to public crises.
Infectious disease surveillance is a continuous, complex and inefficient process because it involves a large number of independent agencies that must report to local and national government information systems.
With the help of blockchain technology, the new coronavirus prevention and control, with the help of blockchain, has the advantages of trust, sharing, transparency, traceability and privacy protection. It may be able to shorten the response time in a timely and comprehensive manner.
Blockchain can improve the response to crisis events by sharing data among all participants, selective privacy and ensuring data security, and can realize the automation of safe data sharing and storage in different levels of health organizations.
At the same time, the traceability of the blockchain, through the module based on geographic location, can quickly locate the active location of the infected person.
By reducing mortality, morbidity and economic costs, blockchain technology can simplify the early warning and monitoring of epidemics, the immediate verification of blockchain and the advantages of data availability, can speed up the response speed of health systems in emergencies, which It makes real-time disease surveillance nationwide and even global possible.
Regarding the epidemic in Wuhan, we have also seen that many medical institutions and scientific research institutes are actively using blockchain technology to improve their response to epidemic prevention and control.
For example, the epidemic prevention and control cooperative system in Nansha District of Guangzhou, this system based on the "Nansha City Brain", has a total of five major functional modules, namely the epidemic prevention and control command center, epidemic situation management, epidemic prevention material management, enterprise resumption management, and epidemic prevention Information reporting etc. The epidemic focus on personnel, the latest outbreak data, scheduling of resources, are aggregated together by block chain technology. As a result, data from multiple departments such as the Bureau of Political Affairs and Statistics, the Political and Legal Affairs Commission, the Lai Sui Bureau, and the Health and Health Bureau have been broken through.
It is worth mentioning that the Nansha district epidemic prevention and control collaborative system also incorporates data visualization technology, using various data analysis methods such as trend statistics and heat maps. As a result, information on the epidemic development trend, hospital beds, epidemic prevention and control materials, high-speed expressway entrances and exits, etc. became clear at a glance.
The medical artificial intelligence team of the School of Mathematics and Statistics of Xi'an Jiaotong University has developed an online consultation and risk screening system for the new crown virus for the Second Affiliated Hospital of Xi'an Jiaotong University. The system background supports blockchain technology for patient medical record management.
When the epidemic has passed, from the government, regulatory authorities to medical institutions, there may be more people to rethink the value of blockchain and use blockchain to upgrade the governance model. Block-based chain
Ebola virus tracking system SERIS
As early as 2018, the Brazilian research institute FGV Foundation began to study the role of blockchain technology in the prevention and control of infectious diseases.
Researcher Flavio Codeco Coelho of the agency pointed out in a paper published that year that using blockchain technology, people can create powerful, open, and low-cost disease surveillance solutions. In the same year, Jia Bainga Kangbai, a scholar of tropical infectious diseases at the University of Munich in Germany, proposed a blockchain system for tracking Ebola outbreak-SERIS.
Ebola virus is a virulent infectious disease virus that can produce hemorrhagic fever in humans and primates (its biological safety level is 4 and AIDS is 3), and the mortality rate is between 50% and 90%.
SERIS is an intelligent Ebola monitoring platform built on the basis of blockchain and Internet of Things technology. You can upload data obtained by Internet of Things devices on the blockchain platform. These devices monitor CDRs, censuses, and national transportation of mobile phone companies. The system and the Ebola vaccine production database for real-time Ebola contact tracking, transmission mode monitoring and vaccine delivery. After modification, the platform can also be used for monitoring such as influenza, cholera, malaria, measles, dengue fever, polio, etc. .
SERIS will serve as the main server for the National Ebola Surveillance Unit (NESU) database of the host country. The system consists of a radio frequency identification system called SmartIRFID. The function of SERIS is to create an intelligent database marking Ebola confirmed cases, suspected cases and suspected cases, and to spread these marked cases to intelligent central devices through the Internet.
American Centers for Disease Control and Global Health Association
Blockchain application
At the end of 2018, the US Centers for Disease Control and Prevention (CDC) announced a partnership with (IBM) to develop a blockchain application, dedicated to automatically collecting health data through blockchain technology, keeping the data safe, and recording visitor information. Its goal is to help alleviate American epidemic, antibiotic prescription and opioid crisis.
Relevant materials show that the US CDC expects that blockchain technology can be optimized in many processes of disease prevention, including: event detection, situational awareness, event reporting, monitoring / life statistics, sample tracking, result reporting, and epidemic management.
The International Health Organization-Global Health and Safety Organization (GHSA) advocates the use of blockchain technology on the basis of feasibility studies in the medical field. GHSA proposed a public safety monitoring model based on blockchain.
Under the three major disease control categories (ie prevention, detection and response), the model has a large real-time monitoring range for the GHSA action plan and the detection of non-communicable diseases, which can detect threats in time and report them to the relevant health departments , You can avoid many disease outbreaks by preventing threats early and responding effectively to them in a powerful way.
Today, real-time monitoring systems based on blockchain have been implemented in countries such as the United Kingdom, the United States and Canada. In the UK, they have implemented a blockchain in the emergency department symptom monitoring system. Canada has also implemented emergency department symptom monitoring at the regional level.
Another excellent example of blockchain application is the European Antimicrobial Resistance Surveillance Network. Therefore, the blockchain application can maintain the main functions of traditional disease surveillance, and it can be more effective and timely than traditional surveillance in terms of coverage, durability, consensus, selective privacy, uniqueness, and shortened response time. .
On the other hand, in China, we are still far away from the international leader in the application of public safety and disease prevention and control blockchain. If the epidemic can fully stimulate the potential of the blockchain-based shared monitoring system and medical big data, and apply it to the tracking of infected people, suspected patients, and contacts, this is undoubtedly a major cause for China's medical and health care. Great progress.
