Sure enough, at the annual meeting of the World Economic Forum in 2018, the blockchain played a strong voice.
The “decentralization†model of the blockchain fits well with the theme of this year’s Davos Forum “Building a Community of Destiny in a Differentiated Worldâ€. In the view of Schwab, founder and executive chairman of the World Economic Forum, the blockchain will It is the key technology of the fourth industrial revolution.
Health has been recognized as the fifth-largest need for human beings after the "clothing, food, housing and transportation". How will technological innovation, including blockchain technology, change the traditional medical model that has lasted for many years? Do people really want to see themselves in the future?
On February 5th, "China Economic Weekly" reporter interviewed the blockchain expert who just returned from the Davos Forum, the world's first AI medical chain (AIDOC) Asia Pacific consultant, former Baidu big data business leader Wu Shizhan .
How can artificial intelligence improve the efficiency of doctors?
In Wu Shizhan's view, with the aging of the global population and the increase in the prevalence of chronic diseases, under the current situation of severely asymmetric information such as medical records and diagnostic data, the new model of blockchain implants will definitely benefit the people, smart medical care. The popularity of hardware will also make people's vital signs data more accurate.
First of all, the advancement of science and technology will be reflected in the leap-forward improvement in the rate of diagnosis and treatment.
“Currently, a patient visit requires medical data analysis, including structured data and unstructured data. For example, patient medical records, patient information, including imaging data, laboratory results, test results, surgical records, and various data for real-time monitoring, etc. By analyzing these data, providing patients with a variety of treatment options, and sorting the programs to give a medical basis, doctors select a treatment plan that is truly suitable for patients." Wu Shizhan said, "The current distribution of medical resources is not The average status quo determines that the treatment process is very complicated and lengthy."
Wu Shizhan believes that there is a large amount of space available for artificial intelligence technology to improve efficiency in the current diagnosis and treatment process. For example, intelligent image-assisted diagnosis technology greatly facilitates the doctor to quickly judge the patient's condition. "With this technology, the reading time of each chest piece is only 10ms, which effectively improves the reading speed of doctors by 30 times, reduces the amount of manual reading by 90%, and reduces the rate of missed diagnosis by more than 40%, greatly improving the imaging doctor. Work efficiency."
In addition to intelligent image-assisted diagnosis, doctors also need to analyze the medical records to achieve medical record data, which involves natural language understanding technology. According to Wu Shizhan, the intelligent document identification platform that has been commercially used in the industry is an OCR (optical character recognition) text recognition product that incorporates deep learning, covering all top three hospitals in China and most mainstream county and municipal hospitals in China. More than 3,000 assay forms support the identification of test indicators and the intelligent understanding of medical language. The recognition accuracy rate is over 97%. “This technology solves the problem of standardized collection and collation of medical data and realizes the first step in electronic medical records.â€
Manual reading has been an indispensable part of the diagnosis and treatment process.
Personalized vital signs are fully digitized
Currently, medical data is exploding. According to IDC, the global medical data volume will reach 40 trillion GB by 2020, about 30 times that of 2010.
Although medical data is vast, there are serious data island problems. “The physical examination is a physical examination, the hospital is a hospital, the data of the initial investigation and the review are separated, and the medical institutions do not communicate with each other. The big data is centralized, and there is no way to trace it, nor can it ensure that the data is not Tampering or ruining." Wu Shizhan said.
At this stage, the blockchain has a natural advantage in the medical industry . Wu Shizhan said that the blockchain is essentially a distributed accounting technology, which can be regarded as a database of decentralized nodes from the perspective of data. “Because all parties' behaviors are traceable, ensuring that data is not falsified or destroyed, the technical characteristics of the blockchain are more applicable to medical scenarios. This is the key to breaking the medical reform of the blockchain, and it is also the technology to help ordinary people. The most worthwhile expectation of managing health."
What are the current pain points in the medical industry that can be solved by the blockchain with natural technology advantages? Specifically, the blockchain distributed structure can be applied to medical data sharing; the non-tamperable timestamp feature can solve data and device traceability and information anti-counterfeiting problems; its high redundancy and the advantages of complex privilege of multiple private keys It can solve the defects of safety certification of medical information technology. “This allows us to establish a mechanism of mutual trust and sharing and standardize medical behavior through blockchain technology, thus providing an innovative way to establish a transparent and credible new relationship between hospitals, medical insurance and medicine.†Wu Shizhan Say.
Can you earn money when you see a doctor?
How does the abstract concept turn into a realistic scene? Wu Shizhan introduced the concept of “bit digital people†combined with artificial intelligence and blockchain.
First, the bit-digit person is a comprehensive digitization of personal vital signs. "People use human wearable devices, intelligent hardware, sensors, etc. to continuously upload human vital signs data, health data and disease data to the Tianyi chain, forming a digital mapping object of the user ontology in the network, making quantitative health management become may."
Secondly, the Tianyi Chain Network will analyze the real-time physical signs data, and can detect abnormal physical data in time to prevent unknown disease risks. "Our various vital signs will be digitized in real time or in near real time by various types of intelligent medical devices in or out of the body. The whole person is digitized. When the body is slightly abnormal, the data fluctuates. These devices precede us. Get the perception and inform us to seek medical treatment. Some diseases can also directly transmit relevant body data to the artificial intelligence doctor through the network, which can assist diagnosis, predict and analyze the disease data, and finally be diagnosed and treated by human doctors. The robot performs surgery," Wu Shizhan said.
This "scenario" that sounds very advanced has actually appeared in film and television works. In the popular Hollywood movie "Space Traveler" in 2017, the heroine used the artificial intelligence medical robot in the capsule to treat the male protagonist. The medical robot comprehensively analyzed the male subject's vital signs and gave a series of The treatment plan was finally implemented.
The scenes on the screen may not be far from reality. Wu Shizhan said, "In the near future, we can use our wearable devices, health management apps, smart hardware and even smart homes, sensors and other devices to upload our physical signs in real time and get health management advice and medical advice from artificial intelligence doctors. It is very convenient to get the services provided by doctors, hospitals, technical service providers, insurance companies, genetic companies and health management agencies."
Perhaps the most incredible thing is that the future medical treatment may change from "spending money" to "making money." Wu Shizhan said, “We can not only afford high cost, but also get a thoughtful and intelligent AI doctor to protect your health, and the vital signs uploaded by patients, after the digital identity, can also pass the form of “mining†Get token rewards and create huge economic benefits."
