(Fighting new crown pneumonia) Intelligent prevention and control of remote diagnosis and treatment: Chinese system helps global war "outbreak"

China News Network, Beijing, March 16th (Reporter Sun Zifa) "The Tsinghua team developed a self-assessment evaluation system for new crown virus infections developed for individual residents. Two weeks ago, statistics have been downloaded and used by more than 10 million people in 20 countries." New artificial diagnosis system for new crown pneumonia has been shared to South Korea, the United States and Italy "...

Dispatched by the medical treatment team of the new crown pneumonia epidemic joint prevention and control mechanism of the State Council, Prof. Dong Jiahong, academician of the Chinese Academy of Engineering, dean of the Tsinghua University School of Clinical Medicine, and executive dean of Beijing Tsinghua Chang Gung Hospital led a national telemedicine team composed of Tsinghua University and the Chinese Medical Doctors Association The working group has been supporting Wuhan for almost a month. On the afternoon of the 15th, he accepted a collective media interview remotely through a network video connection, introducing the research and development progress of the prevention and control of information technology services such as artificial intelligence, and the application of related system products at home and abroad.

Artificial intelligence: emergency research and development of a batch of intelligent epidemic prevention and control systems

Dong Jiahong said that in response to the outbreak of the new crown pneumonia epidemic, Tsinghua University urgently set up a scientific and technological task force that combines medical and industrial work. It consisted of 8 medical experts from Beijing Tsinghua Chang Geng Hospital and multi-departmental artificial intelligence and new-generation information technology experts from Tsinghua University. The tackling key group has focused on several important aspects of epidemic prevention and control, and has been working on research and development as soon as possible since the beginning of the first year of the Rat. It has innovatively developed and deployed a number of artificial intelligence technology products.

The new crown virus infection self-assessment evaluation system for residents. The public responds to design questionnaires through smartphones. The system program can intelligently analyze and assess people's infection risks and provide advice on whether to seek medical treatment. This will alleviate the social panic caused by the spread of the epidemic and guide residents' rationality. Medical treatment plays an important role.

The community intelligent epidemic prevention and control system automatically reports to the grid staff and the community center terminal after self-assessment by the community crowd. Using such intelligent means, it can realize the dynamic surveillance of the entire population epidemic situation in the community, thereby overcoming the low efficiency and easy omission of traditional manual methods. Disadvantages greatly improve the accuracy and efficiency of community epidemic prevention and control.

The intelligent outpatient pre-screening and triage system is developed for the influx of large numbers of people into the hospital during an outbreak. This system is developed to avoid crowd gathering and cross-infection. This system can quickly and accurately classify and subdivide the medical population according to the risk of infection, which effectively avoids in-hospitals. Cross-infection also reduces the load of hospital fevers and saves medical protection materials.

During the outbreak, a large number of patients with new coronary pneumonia were diagnosed and suspected cases were checked. As long as the patient's symptoms, epidemiological history, and CT images were imported, the new coronary pneumonia artificial intelligence diagnosis system could make a diagnosis within 10 seconds. 3 The accuracy rate of more than 10,000 cases is 98%, which greatly improves the diagnosis rate of patients with new coronary pneumonia and lays the foundation for rapid and timely treatment. At the same time, the system can also help grass-roots community hospitals and doctors improve their diagnostic capabilities.

Isolation ward mobile physiological indicator monitoring system can monitor patient's body temperature, ECG, heart rate, breathing and oxygen saturation and other physiological indicators, and reduce the contact and exposure of medical staff and patients, reduce the risk of nosocomial infection, and can continuously provide patients with dynamic physiological monitoring, Provide a basis for accurate judgment of the condition and treatment decisions.

After arriving in Wuhan, the medical team quickly deployed a series of innovative new and developed new medical technologies for the diagnosis and treatment of pneumonitis pneumonia in Lei Shenshan Hospital, Wuhan Western Union Hospital, Central South Hospital, and Tianyou Hospital. Through research, we learned the needs of the community, and developed an artificial intelligence monitoring system specifically for the rehabilitation population in the isolation area to achieve efficient and accurate monitoring services for the entire rehabilitation isolation population. So far, it has provided accurate services for more than 11,000 rehabilitation patients in 95 isolation areas.

In addition, research and development of artificial intelligence equipment such as isolation ward robots and throat swab robots for nucleic acid detection have been deployed to first-line hospitals and are undergoing clinical testing.

Remote diagnosis and treatment: break through a number of hard core technologies to achieve "immediate presence"

Dong Jiahong pointed out that the biggest difficulties and pain points of traditional remote diagnosis and treatment methods mainly include problems such as the difficulty of transmitting large amounts of information, delays at the field and remote ends, and poor restoration of medical front-line picture clarity.

"The remote collaborative diagnosis and treatment system platform we developed overcomes these problems. First, it can achieve smooth transmission of high-throughput data; second, there is no delay between the field and the remote; third, field doctors and remote experts can Real-time sharing of patient treatment video screens and all condition information ", so as to achieve the effect of remotely participating experts as if they were" immersive ".

The "immersive presence" of remote diagnosis and treatment is hard to come by. The research and development team has independently innovated at least three key technologies in this regard. The first is data compression technology. The amount of data transmitted from the front to the far end is very large. Compression technology can ensure fast and smooth transmission of data information through the network; second is image enhancement technology to ensure that the remote end image is clearly restored and first-line live images are clearly displayed; third is video image freezing technology, which allows remote experts to freeze at any time during remote diagnosis and treatment as needed Real-time video screen and relevant annotations, fully interact with front-line doctors, guide and guide the operation.

Academician Dong Jiahong, who is also the executive vice-chairman of the Chinese Medical Doctors Association, said that although there were a large number of medical experts in the epidemic on the front line, the infection of pneumonia caused by the new crown virus is very complicated. In addition to the specialties such as breathing, infection, and severe disease, you need to be careful. , Kidney, brain and other specialist experts, so the expert resources are relatively lacking.

Through the remote collaborative diagnosis and treatment system platform, it is possible to mobilize a wide range of rear expert teams across the country to provide remote medical services for the front line. During the outbreak of the epidemic, the Chinese Medical Doctors Association organized nearly 10,000 expert volunteers from more than 40 chapters to participate in remote diagnosis and treatment. The remote collaborative diagnosis and treatment system platform was used to achieve seamless connection across the country and the front line of Wuhan, Hubei, and provide multi-disciplinary and efficient consultation. The treatment of epidemic patients played an important role.

He said that the remote collaborative diagnosis and treatment system platform application has been deployed to a number of designated hospitals in Wuhan, such as Lei Shenshan and Tianyou Hospital, and has organized multiple remote consultations of critically ill cases in the country. "For a critically ill patient being treated, Raytheon Hospital will organize a multi-disciplinary multi-disciplinary expert consultation on the 16th. Experts in Beijing, Shanghai, the United States and Australia will use the remote collaborative diagnosis and treatment system platform for remote consultation."

International Sharing: Chinese System Helps Global War "Outbreak"

In response to the spread and raging trend of the current global epidemic, the academician Dong Jiahong's team will independently innovate and develop epidemic prevention and control artificial intelligence systems and remote diagnosis and treatment systems, all of which will provide shared applications for the international community at no cost, and use high-tech Chinese systems to help the global war "outbreak" action .

Dong Jiahong introduced that the new crown virus infection self-assessment evaluation system is publicly released through the Internet, and anyone in the world can download and use it from the Internet. At present, the system has been translated into five foreign languages: English, Japanese, Korean, Persian, and Italian. In the future, the corresponding language versions will be provided as required. "According to statistics two weeks ago, more than 10 million people in 20 countries around the world have downloaded and used this self-assessment evaluation software."

The new artificial intelligence diagnosis system of New Crown Pneumonia is based on the data of thousands of confirmed patients in China, and it has developed key algorithms such as special algorithms and three-dimensional quantification of lesion range. The system has been shared to South Korea and the United States.

He emphasized that China ’s self-developed high-tech product solutions, such as the epidemic prevention and control artificial intelligence system and remote diagnosis and treatment platform, were actively shared by any country in need in the world. While exporting the Chinese system to the world, the R & D team is also willing to jointly carry out cooperative research and development at the technical level to contribute to the localization of the Chinese system in accordance with the specific national conditions of the host country. These international sharing and cooperation "are free and unpaid volunteers. action".

Dong Jiahong believes that after the epidemic "big test", China ’s national defense control and rescue experience is of great significance for the international community. Although the closure of the city may not be implemented in some countries, the construction of a square cabin hospital and early detection, early reporting, and early isolation are needed. The international community can learn from the "four early" principle of early treatment and the "four concentration" strategy of centralized patients, experts, resources, and centralized treatment.

Future applications: can be replicated and spread to infectious disease prevention and control and chronic disease management

The artificial intelligence system and remote diagnosis and treatment platform technology products developed by Tsinghua University are integrated solutions for the entire process for epidemic prevention and control. They can be divided into three links: pre-hospital, in-hospital and post-hospital. Prevention and control play a role in improving the hospital's diagnosis and treatment efficiency and doctor's diagnosis and treatment performance in the hospital, and after the hospital, it provides accurate whole-process monitoring and return visits for rehabilitation patients.

Dong Jiahong pointed out that the intelligent prevention and control and remote diagnosis and treatment system is universal. "What the R & D team wants to do now is to hope that this system can also be the whole process management for the recovery of other chronic or acute diseases in the future." Crowd, full cycle, and all-round health management, providing information, intelligent and modern service tools.

In view of the reproducibility of future promotion, the personal self-assessment evaluation system can be extended to any disease, and different special self-assessment assessment systems can be designed for high-risk groups of different diseases to serve personal health assessment and improve national health awareness. The artificial intelligence monitoring system for the rehabilitation population in the isolation area can be used for the long-term management of other diseases in the future, and it can solve the shortcomings of post-operative management commonly faced in China. Through this system, it can realize the patient's full-course management, dynamic monitoring, and regular prompt follow-up visits. New problems are dealt with in a timely manner, which greatly improves the treatment effect.

Talking about the topic of prevention and control of infectious diseases in the post-epidemic era, Dong Jiahong put forward the need to attach great importance to the construction of "strong grassroots units", change the very weak status of community medical institutions, and build a "firewall" for community prevention and control. The people still rushed to the big hospitals. "It caused paralysis in the big hospitals. No matter how big the hospitals are, they can't cope with it. It is also easy to cause cross-infection in the hospital and cause the epidemic to spread. Therefore, community hospitals must strengthen ".

At the same time, general hospitals are also seriously inadequate in the prevention and control of infectious diseases. In this regard, they must be prepared. In general, they must establish sufficient space facilities and equipment resources to respond to epidemic outbreaks. Affect emergency response. (Finish)
