WeDoctor Cloud Leverages Blockchain and DOA Technologies to Establish a Trusted Foundation for Healthcare Big Data Interoperability

On August 30, the Zhejiang International Health Industry Summit was held in Hangzhou, where tens of thousands of guests from home and abroad, including experts in healthcare, internet, and AI, jointly explored innovation and entrepreneurship in “Internet + Healthcare.” It was learned at the press conference that WeDoctor Cloud, as a representative of Zhejiang’s health and medical big data, has innovatively introduced blockchain and DAO technologies to ensure the security and traceability of health and medical big data. Hu Hongxia, Senior Vice President and Chief Technology Officer of WeDoctor Group, stated that the capabilities in IoT, artificial intelligence, and cloud computing accumulated by WeDoctor Cloud over eight years are now open to the entire industry, promoting data collaboration, workforce coordination, and resource synergy in the health and medical sector.

Since its inception with online appointment registration in 2010, WeDoctor has, over the past eight years, deeply integrated a “full-process” and “comprehensive” medical service ecosystem. It has achieved cloud-based transformation of hospital front-office services, clinical diagnosis and treatment, physician collaboration, primary healthcare and health management, regional medical and health services, and payment systems, thereby weaving an internationally scaled medical cloud—WeDoctor Cloud—and establishing a human-centric cloud platform that integrates software, hardware, and operational services.

In the process of extensively connecting hospitals and serving the government and the industry, WeDoctor Cloud has accumulated substantial health and medical big data resources and service capabilities. It has achieved cloud-based diagnosis and treatment through more than 100 regional medical service bases, including Internet Hospitals, Medical Consortia, and WeDoctor General Practice. By linking 19,000 healthcare service outlets, it has established China’s largest prescription-sharing platform, enabling synergy among “medical services, prescriptions, pharmaceuticals, and insurance.” Through population health information platforms, a provincial-level cloud system connects upward to the national level and downward to city, county, and district levels, realizing regional cloud-based health and medical services. By integrating online medical insurance payments in provinces and cities such as Sichuan, Tongxiang, and Yuhuan, it has achieved cloud-based integration of basic medical insurance, commercial insurance, and out-of-pocket payments. Furthermore, through an intelligent tiered diagnosis and treatment platform, it connects medical institutions across five levels—province, city, county, township, and village—leveraging dynamic live data, such as electronically updated health records, to guide personalized health management for residents.

Recently, the People’s Daily reported that Pingdingshan City in Henan Province has explored an innovative “Internet + Healthcare” model through collaboration with WeDoctor, significantly improving the efficiency of family doctor services and basic public health services. Relying on WeDoctor Group, Jia County in Pingdingshan established an “Intelligent Tiered Diagnosis and Treatment Platform,” connecting the four-tier healthcare system spanning villages, townships, counties, and cities. The county has also innovatively introduced two AI systems from WeDoctor Cloud—Ruiyi Intelligent Doctor and Huatuo Intelligent Doctor—for grassroots physicians. As a result, the county has achieved a health record establishment rate of 95% and a family doctor contract signing rate of 80.88%. Currently, this model has been promoted and implemented across various regions in China, including Hunan, Ningxia, and Shandong, providing big data services to tens of millions of residents.

Eric Schmidt, Chairman of Alphabet (Google’s parent company), has stated that the greatest application opportunity for artificial intelligence lies in healthcare, and China represents the largest application scenario for healthcare AI. In addition to the Ruiyi Intelligent Doctor and Huatuo Intelligent Doctor, WeDoctor Cloud, in collaboration with the Zhejiang University Ruiyi AI Research Center, has developed an auxiliary diagnostic system covering more than 20 medical specialties, thereby digitizing and intelligentizing the expertise of leading specialists. It is reported that WeDoctor Cloud’s fundus disease auxiliary diagnostic system can screen for 12 types of lesions in a single pass, achieving a prediction accuracy rate of 94%; the average sensitivity for pulmonary nodule auxiliary diagnosis is 95%; the average sensitivity for colposcopic detection of malignant lesions reaches 90%; and the average sensitivity of the gastric cancer pathology auxiliary diagnostic system is 96%.

“Connectivity and cloud migration have broken down the walls of hospitals, gradually achieving synergy in data, workforce, and resources, bringing breakthrough capability enhancements to the entire healthcare industry,” said Hu Hongxia. Through years of accumulation, WeDoctor Cloud has built a multi-dimensional intelligent computing system based on big data and a continuously optimized medical service system. Moving forward, it will continue to open up its capabilities in big data, cloud computing, and artificial intelligence to the entire industry, empowering the sector as the infrastructure and computing engine for the health and medical industry.

“Where there is free flow, there is no pain; where there is pain, there is no free flow.” For healthcare big data to develop, true interoperability of data must be achieved. However, due to the unique nature of healthcare, achieving interoperability in a secure and reliable environment has become the key to the development of healthcare big data.

“WeDoctor Cloud has introduced blockchain and DOA technologies to build an industry-leading security system, leveraging the immutability and robust security controls of these new technologies to address trust issues in data interoperability,” explained Hu Hongxia. She highlighted that by fully utilizing the encryption, authorization, and tracking capabilities of blockchain technology, a foundation of trust can be established among individuals, between individuals and institutions, and among healthcare institutions in medical and health applications.

In addition to leveraging blockchain, WeDoctor Chain has also introduced Digital Object Architecture (DOA) technology developed by Robert Kahn, the “Father of the Internet.” As a key infrastructure for data resource management systems, DOA technology provides capabilities such as globally unique identification, information resolution, information management, and security control.

It is understood that Weiyi Chain has been pioneered in the Heilongjiang Population Health Information Platform and the Prescription Sharing Platform. “Based on blockchain-based data notarization and verification, we leverage blockchain to prove the authenticity and immutability of data, providing traceability functions for regulatory authorities and medical institutions, preventing data misuse, enabling end-to-end monitoring of digital assets, and building a foundation of trust for data interoperability,” added Hu Hongxia.
