In 2015, the overall market size of the medical Internet of Things was 41 billion yuan. IDC expects to grow to nearly 200 billion yuan by 2020 and a compound growth rate of 36.1% from 2015 to 2020. From smart medical care to mobile medical care, from telemedicine intervention to medical Internet of Things, as an emerging industry with high hopes, the medical Internet of Things is quietly affecting people's lives. As the most widely used application system affecting the public, the medical information system, intelligent mobile clinical, surgical teaching, medical device tracking, intelligent security system, patient accident alarm and rescue system, wireless positioning system, wireless temperature monitoring, The types of industries such as intelligent wards have shown a trend of gathering and development.
With the overall advancement of China's new medical reform, the medical Internet of Things has also received continuous support from the state and local governments. At present, the support for the development of China's medical IoT industry is focused on supporting the development of Internet of Things systems in the fields of family and community telemedicine, real-time monitoring of inpatient health, medical device circulation and management.
The data shows that there are about 300,000 medical institutions in China today, including more than 190,000 hospitals; among them, there are 150,000 private medical institutions, accounting for 51% of the total number of medical institutions, and about 9,000 private hospitals, accounting for 3% of the total number of hospitals. For hospitals, hospital management has long been the focus of attention of the government, the health department, and the public, in order to ensure the quality of medical care due to the management of instruments, equipment, materials, medicines, and a large number of personnel and patients.
Especially in recent years, the failure of the last Chinese medical reform has made people fully realize that whether the hospital's management control is scientific will directly affect the future development of the hospital. Without scientific medical quality management, the overall development of the hospital becomes passive. Water, no wood. At the same time, the reform of the personnel system and the reform of the medical system that are currently being promoted have also put forward clear requirements for the hospital. Under this circumstance, how to break through the three difficult points of hospital logistics management, medical safety management, and medical equipment management becomes a strategic choice to ensure that the hospital can get rid of the cumbersome management work.
Problem 1: Hospital Logistics Management
Hospital logistics covers the daily operations and management activities of all business units in the hospital. These include:
(1) Transmission of hospital documents, including medical records, doctor's prescriptions, inspection reports, medical bills and accounts, etc.; (2) medical materials transmission, including medicines, medical equipment, sterile medical materials, surgical instruments, etc.; Medical specimens are delivered, laboratory specimens, pathological specimens, etc.; (4) Hospital logistics, including procurement, loading and unloading, storage and storage, and supply of various auxiliary materials.
Because the logistics system of the hospital involves the entry and exit of large-scale drugs, equipment, equipment and reagents, if the logistics management of the hospital is wrong, it will greatly affect the stability of medical quality. For example, in 2013, the Peking University People's Hospital reached 3 billion yuan, and the 44 hospitals managed by the Health Planning Commission totaled more than 100 billion yuan. In general, domestic hospital logistics still basically stay in the functional logistics management stage, such as pure material procurement, warehousing, transportation and supply. These logistics functions lack organic links to each other. The hospital logistics network is poorly designed. For example, most hospitals in China use a large-scale full-time delivery team. The trolleys and dedicated elevators make the flow of people and logistics mixed. Item delivery efficiency is low.
Medical IoT is an information sensing device such as radio frequency identification, infrared sensor, global positioning system laser scanner, etc., which connects drugs, instruments, equipment, reagents, etc. with the Internet according to the agreed protocol, and exchanges information and communication. Enable intelligent identification, location tracking, monitoring and management.
Drugs in pharmacy drug stores or hospital pharmacies can be managed using RFID technology. By deploying a wireless sensor network and attaching RFID tags to valuable drugs or dangerous drugs, you can get real-time drug batches, warehousing time, and inventory rack positions. Information such as time of departure, whereabouts, patients who use drugs, and doctors to classify, store, distribute, audit, and track drugs. In this way, through the medical Internet of Things, the traceability of the drug in the whole process can be realized, and the management of high-value consumables can be automatically tracked. It can be said that the medical IoT application in the hospital logistics transportation system not only can effectively connect the logistics transfer room and the front-line department departments' item transmission channels, reduce various uncertainties in the manual transmission process, and greatly promote various items in the logistics link. Work has changed to standardization. For example, the medical Internet of Things can monitor the temperature of cold chain products. By setting it on the temperature sensing electronic tag, in the process of cold chain transportation of vaccines and other items, the temperature sensor will change the temperature change every fixed time. For electronic signals, the RFID chip senses and records the signal. When the destination is reached, the staff can scan the electronic tag with the card reader to find out the temperature change of the vaccine in the refrigerator during the whole transportation.
Problem 2: Medical Safety Management
The complexity of medical safety management is manifested in: the division of professional division of labor and interpersonal relationship is extremely complicated; the relationship between medical care, doctors and patients, medical technology is complex; the composition of personnel is the most intensive group of technology and knowledge; the management procedures, skills and methods are complex and diverse, and coordination The cost is high; at the same time, the quality assurance is managed by doctors' self-discipline and system mandatory. In the traditional medical safety management method, management and control can only be managed by manual placement and fixed editing. Due to the mobility of the post, the variety of drugs, and the excessive number of medical services, medical safety cannot be guaranteed, thus aggravating functions, management, and personnel. The chaos of division of labor.
So, how does the medical Internet of Things solve the problem of medical safety management?
The medical Internet of Things can play a role in the doctor's clinical operation, patient waiting time, key departments, key medical management, ventilator and device-related infections, perioperative management, etc., and enhance the hospital's medical safety management.
For example, during the operation, the surgical procedure can be standardized, and the perioperative medical safety can be increased to prevent surgical errors. For patients with critically ill patients, blood products can be traced throughout the process to improve blood safety. The application of intelligent drug management can ensure the safety of medication and prevent drug errors.
In addition, in the traditional mode of work, doctors or nurses need to carry a large number of medical records with them, and record medical records by handwriting. This is not conducive to the improvement of the efficiency of the rounds, and it is easy to produce errors due to the entry and identification. Through the medical Internet of Things, doctors can more accurately, timely and comprehensively understand the patient's detailed information through the portable wireless Internet-enabled handheld computer, so that patients can receive timely and accurate diagnosis and treatment.
Doctors and nurses can also use the medical IoT monitoring system to effectively monitor the ward and patients in real time, so that the doctor or the patient's family can always grasp the patient's treatment. For example, doctors and nurses can track and master the physiological condition of patients with RFID wristbands through wireless sensor networks. The hospital can also track the patient's position, drugs and medical waste to determine the patient's position, which can ensure that the patient can receive timely rescue treatment in case of sudden illness. The medical Internet of Things can even locate medical waste, clarify the responsibilities of hospitals and transportation companies, prevent illegal dumping of medical waste, and cause environmental pollution in hospitals.
Problem 3: Medical Device Management
There are thousands of medical instruments and equipment in hospitals, and the current fixed assets of medical equipment account for a large proportion of the total fixed assets of hospitals. As the scale of hospitals continues to expand and the variety of hospital equipment continues to evolve and the number of devices increases, the equipment management process for equipment is becoming more complex. For example, some mobile device locations cannot be tracked in real time. It is time-consuming and labor-intensive to find equipment. It is not possible to accurately count equipment usage, usage time, and usage status, which is not conducive to management. The management of users is not sufficient, including borrower departments, positions, names, Contact information, etc.; some idle devices can not be discovered and reclaimed or loaned in time, and the equipment utilization rate is low.
So, how does the medical Internet of Things solve the problem of medical device management?
As with the management of medical related items, the ultimate goal of medical device management is to keep medical equipment in good operating condition and to ensure that the social, technical and economic benefits of the hospital are maximized.
Through radio frequency identification technology, the hospital can record the situation of medical device users, including borrower departments, positions, names, contact information, etc.; also can register the equipment inventory status, the status of the equipment, including the quantity, whether to be repaired, Whether to maintain, use years, equipment prices, manufacturer information, after-sales service, instructions for use, etc.; at the same time, the medical Internet of Things and the equipment information security system connection, allowing managers to know their history, time of use, users, Use location, fault record, etc., and implement regular maintenance and maintenance of the equipment based on these data, realize electronic equipment files, improve work efficiency, and implement equipment usage supervision to ensure equipment utilization.
It can be said that the equipment management system of Baoli Hospital based on Internet of Things technology has the characteristics of good practicability, high stability, strong expansibility, and ease of use. The system can effectively manage the basic medical equipment of the hospital. Improve the efficiency of medical staff, reduce hospital operating costs and improve hospital operational efficiency. In addition, with the medical Internet of Things as the medium, through the connection of things and things, and the connection of things and people, the hospital can control the physical assets to the greatest extent. Through RFID tags, barcodes, two-dimensional code reading and sensing technology, and 3G communication, intelligent terminals, it can realize the intelligent storage and delivery of medical items, asset inventory, repair and report loss, department management anti-theft and alarm.
According to the â€œKey Tasks for Deepening Health System Reform 2014â€ and the â€œMeasures for the Supervision and Administration of Internet Food and Drug Administrationâ€, the â€œTwelfth Five-Year Development Plan for the Internet of Thingsâ€ and the â€œMedical Device Technology Industryâ€ issued by the General Office of the State Council in early 2014 In the future, China will try to establish a unified medical information sharing platform, and develop a large-scale and clustered intelligent medical industry chain, and strengthen the construction of intelligent medical infrastructure such as medical sensor equipment.
At the same time, various localities have recently issued documents to support the development of the medical IoT industry. For example, in the "Opinions of the Chongqing Municipal People's Government on Accelerating the Development of the Internet of Things", telemedicine has become one of the key application areas for the creation of the Internet of Things in the city. At present, more and more regions have begun to adopt sensing technology to strengthen the management of medical devices, drugs and medical processes, and at the same time develop new intelligent medical and health services and applications based on communities and families to realize a low-cost intelligent medical system.
The author believes that the total market size of medical services should have a large increase, but the growth rate may lag behind the total size of the Internet of Things market. The reason for this inference is that the entire IoT industry is still in its infancy, and the industry chain and business model are not mature enough. The current development of the Internet of Things market relies mainly on government support.
