With the development of information and communication technology and the popularization of mobile phones, electronic healthcare (E-Health) has received high attention and rapid development. By using information and communication technology to improve the quality of medical services, it has become an effective method to improve the medical and health conditions of the public, especially vulnerable groups. The current healthcare reform in the United States includes a health informatization program, which involves investing $75 billion over five years to thoroughly reform the US healthcare system through standardized and electronic health information systems for all.

1、 The necessity of building an "electronic healthcare" system.

The promotion of electronic healthcare is of great significance in effectively addressing the increasing costs of healthcare, the relative scarcity of medical resources, and the problem of expensive and difficult access to medical care for vulnerable groups. It is an effective way to promote the equalization of public medical services. Firstly, it is conducive to alleviating the pressure of medical resource scarcity. The most scarce medical resource among developing countries and vulnerable groups is doctors. China only has 14 doctors per 10000 people, which is less than half of developed countries. In 2009, the total number of medical institutions (including village clinics) in China reached 5.2 billion. In addition, the aging of the domestic population continues to intensify (the number of elderly people aged 60 and above in China has reached 300 million), and the prevention and treatment of epidemics and chronic diseases have become a focus, highlighting the need for medical care. Establishing an electronic healthcare system and implementing remote and self-service healthcare through information technology can help alleviate the pressure of scarce medical resources.

2、 It is conducive to improving the modernization level of medical services.

The rapid development of medical information technology and the construction of an "electronic healthcare" system are conducive to the modernization of medical services in China. By utilizing M2M technology and existing communication networks, remote patient data can be transmitted to various medical institutions, doctors, or other medical service personnel, making it convenient to access specific websites at any time to understand the patient's physical indicators or other data. By utilizing wireless sensor technology, various data such as heart rate, blood pressure, respiration, blood oxygen, electrocardiogram, and movement patterns of patients can be collected and transmitted to wireless gateways anytime, anywhere. There are even digestible sensors to monitor medication administration. Cloud computing technology provides a foundation for patient pattern recognition, which can greatly reduce the workload of doctors and enable a small number of top doctors to share their medical experience with a large number of patients. Intelligent terminal technology provides doctors with specially designed mobile terminals that are convenient to use, allowing them to handle emergency situations at any time during consultations or other work and life situations. With diagnosis and treatment support based on m-Health, patients can receive high-quality treatment locally without the need to spend time and effort seeking treatment at hospitals with better medical conditions.

3、 It is beneficial for reducing public healthcare costs.

In 2009, the total national health expenditure is expected to reach 1611.88 billion yuan, with a per capita health expenditure of 1192.2 yuan. The total health expenditure accounts for 4.96% of GDP. At the same time, China has entered the age of aging. Common chronic diseases (malignant tumor, cerebrovascular disease, ischemic heart disease, hypertension and diabetes) are hospitalized once, which generally costs more than half of the per capita annual income of urban residents and 1.5 times of the per capita annual income of rural residents. By promoting electronic healthcare, existing medical monitoring devices can be wirelessly connected at a very affordable price, greatly reducing medical costs. Fourthly, it is conducive to the full sharing of medical information. The information-based medical model promotes the sharing of information resources among hospitals at different levels, medical management departments, and patients, achieving cross organizational and efficient network communication and coordination. The sharing and interoperability of information among various participating entities in the medical and health field also makes it possible to track medical and health services throughout the entire process.

4、 Specific suggestions for building an "electronic healthcare" system.

At present, the key applications in the field of electronic healthcare mainly include six aspects: education and notification, remote data collection, remote monitoring, communication and training for medical workers, disease and epidemic transmission tracking, diagnosis and treatment support. Based on the actual situation in our country, the following suggestions are proposed for three levels: medical units, individual patients, and management departments.

一. Informationization of medical institutions

1、 It's telemedicine. Remote medical care includes remote monitoring, and hospitals use wireless sensor technology to keep medical staff informed of relevant situations at any time, enabling timely and effective monitoring and early warning of patient conditions without the need for long-term hospitalization. At the same time, it improves treatment effectiveness and reduces the occupation of scarce medical resources. Remote diagnosis, through the electronic medical record system, image transmission and storage system, and remote consultation system, can build a unified remote medical service platform to achieve remote consultation of difficult and complicated diseases, and achieve resource integration and sharing. Remote training enables healthcare workers to access various information resources through mobile communication technology, enhancing communication between different medical institutions.

2、 It's mobile healthcare. It is recommended to establish community medical service centers in large urban communities and mobile medical service centers in remote and rural areas. Doctors can provide timely mobile diagnosis and treatment for patients through handheld devices such as PDAs. Enable them to handle emergency situations at any time during mobile medical centers or consultations, greatly improving the efficiency of medical staff and saving necessary rescue time.

3、 It's information medicine. Build a medical electronic management system that utilizes computers, mobile phones, PDAs, intelligent terminals, and other methods to achieve electronic and one-stop management of registration, medical treatment, payment, medication collection, and treatment. Simplify the patient's medical treatment process and achieve informationization of the diagnosis and treatment process.

二. Personal health informatization

1、 It is to establish a personal medical advisory mechanism. By using SMS and other means, real-time medical messages (mobile search for disease dynamics, treatment methods, medical and health knowledge, etc.) are provided to provide information on testing and treatment methods, medical services, and disease management. Introducing healthcare services, medical extension services, and health education into households to achieve self-help healthcare for both families and individuals.

2、 It is to establish a personal diagnosis and treatment center. Using Internet of Things technology, develop and promote real-time data collection equipment (such as digital thermometer, digital scanner, intelligent toilet, etc.), so that patients can "self-help" common colds, chronic diseases such as diabetes, etc.

三. Government health management informatization

1、 It is the integration of national medical information and medical insurance services. Firstly, establish an "electronic medical record" and provide a "one card" service for medical records and health records. The government takes the lead in building a national "smart healthcare" information system to achieve information sharing among hospitals, hospitals and communities, medical insurance, health administrative departments, etc. No matter which hospital you visit, you can upload medical records to a unified management system and download them when needed, laying the foundation for medical services including referrals. Secondly, establish a nationwide linkage mechanism for medical insurance informatization, allowing for the transfer of medical insurance relationships across regions. For example, medical insurance cards can be used across provinces, medical expenses can be reimbursed on behalf of other regions, and enterprise retirees can enjoy long-distance pension insurance, achieving the "free migration" of public medical services. Combining with the process of urbanization, we will include migrant workers who have been working in cities for a long time and farmers who have been newly transferred to urban areas into the scope of medical insurance, and achieve the goal of fully covering urban and rural residents with the basic medical security system by 2011.

2、 It is to establish an information-based epidemic prevention and treatment system. The popularization of mobile devices is crucial for preventing and controlling the spread of infectious diseases. Currently, many Chinese countries have established disease reporting mechanisms based on mobile communication technology. After the tests of SARS and H1N1, some regions in China have accumulated and established mechanisms for prevention, publicity, and notification of major infectious diseases, achieving good results. It is recommended to make full use of mobile platforms, integrate the customer resources of the three major communication operators, establish a national epidemic prevention and treatment system, and improve the ability of the whole population to prevent and resist diseases.

3、 It is to establish an electronic medical standard and regulatory system. Firstly, it is recommended that the government accelerate the review cycle for new medical monitoring devices such as IoT wireless medical sensors and transmission products, and establish special approval channels to adapt to the objective situation of rapid electronic product updates. Secondly, it is recommended to establish technical standards for domestic mobile medical products as soon as possible, and the government should establish a special fund to support and encourage domestic enterprises in related industries to start businesses and develop, promote market maturity, and ensure that China's IoT based electronic medical industry maintains synchronous development with the world level (according to a report by McKinsey&Company, the global market for patient testing services using IoT technology will reach up to 50 billion US dollars in 2010). Thirdly, it is recommended that the government instruct the medical regulatory authorities to develop clear mobile medical service standards and accident handling methods, so that the risk management of remote monitoring has a legal basis. The fourth is to instruct the medical regulatory authorities to establish clear regulations on the management and use of patient records, and effectively protect the privacy of personal health information.
