With the widespread development of RFID technology, the possibility of applying RFID technology to trace management in the whole process of medical records is discussed. Analyzed from the advantages of RFID technology’s composition and positioning accuracy, focusing on the application of RFID technology in medical record recovery, cataloging, quality control, feedback, lending and other processes, and summarized the whole process trace of medical records based on RFID technology Management has the advantages of large storage capacity, fast reading speed, high security, accurate medical record tracking, etc., which can save human resources, improve work enthusiasm, and realize the purpose of refined medical record management. Although there are still problems to be solved in the actual application of RFID technology, RFID technology will eventually become the main content of the medical record management mode in the future, and promote the intelligent and scientific management of medical records.
Infinite Radio Frequency Identification (RFID) is a non-contact automatic identification technology that mainly recognizes the target item and obtains relevant data by identifying the radio frequency signal attached to the item. RFID technology has gradually played an important role in many industries. Nowadays, medical reforms are deepening, and hospital management models with high-tech levels are gradually taking shape. Therefore, the application of RFID technology in the field of medical record management has become an inevitable trend, which brings about the era of digital medical record management.
The whole-process tracer management of medical records is an inevitable trend in the development of medical record management in the information age, and an important stage in the digitalization of medical records. The whole-process tracer management of medical records with the introduction of RFID technology can not only realize a scientific and efficient management model, but also Can save manpower and material costs. The whole process of medical record tracking based on RFID technology is to introduce computer technology, network technology and RFID technology into the medical record circulation control process, identify the uniqueness of each medical record, and use RFID technology to connect all aspects of medical record management, which can not only achieve Accurately trace the purpose of each medical record, and quickly query the real-time status information of the medical record.
1. RFID technology background
RFID technology is a comprehensive self-identification technology based on carrier, coding, identification, communication and other technologies. RFID technology mainly uses the spatial coupling of radio frequency signals to achieve contactless information transmission. Different items can transmit different information to achieve automatic identification technology. Compared with other similar technologies, RFID technology has the characteristics of large storage capacity, fast reading speed, long reading and writing distance, strong penetrating power, long service life, and good environmental adaptability. The RFID system should have three basic components, an RFID tag, a number of RFID readers and a background computer. The RFID tag is attached to the object to send out radio frequency signals, and the RFID reader realizes the collection of tag information and the transmission of data back. The read information is transmitted to the background computer, which analyzes the transmitted information and manages the normal operation of the entire tag system. The application of RFID technology to the medical record tracking system is mainly to attach electronic tags to each medical record, install readers in the use positions of clinical departments and medical record rooms, and connect the back-end computer to the port of the medical record tracking system. Managers can accurately query the medical record process and location through the tracer system, and confirm the filing time.
2. Application of tracer in the whole medical record based on RFID technology
2.1 Medical record recall
After the department’s first-level quality control of each medical record discharged from the hospital, the general nurse affixed an RFID electronic tag and sent it to the medical record room from the property. The medical records are sent to the medical record recovery room equipped with RFID readers. The medical record administrator registers the recovered medical records and compares them with the patient information that was discharged from the hospital to get a list of unfiled medical records and the location of the medical records. After the recovery is completed, the administrator can uniformly mark the medical record information in the medical record tracking system as archived.
2.2 Disease code
After the medical record is retrieved, the staff of the coding team will carry out the disease coding work. Install RFID readers in the coding group office or next to the office computer. When the coder archives the medical records within the scope of the work place, the RFID reader can not only track the medical records that have entered the disease cataloging link, but also track the specific location. Coders use ID identification to determine whether the medical records to be catalogued on the day have been archived to the medical record room, so as to effectively supervise the department to file the medical records in time. After the coder has completed the cataloging, he can uniformly mark the status of the medical record as the coded state with one key.
2.3 Quality control of medical records
The coder transfers the coded medical records to the quality control staff. The medical records pass through the quality control office equipped with a reader. The quality control staff can first check whether the transferred medical records match the number of medical records discharged that day. If they do not match, check the medical records through the tracer system The location and working status, then quality control of the medical record, and identification of the medical record status information.
2.4 Medical record feedback
After the medical records are sorted and bound, some medical records need to be placed in the feedback cabinet of the medical record reading room due to missing signatures and missing items. The medical record administrator can form a circulation record of the feedback medical records through the RFID reader installed in the reading room. Since the medical records need to be rectified by clinical medical staff, they are easy to be taken to the reading room or even outside the medical record room. The medical record management staff can feedback when the medical record was taken out of the reading room through the background data monitoring to find the whereabouts of the medical record.
2.5 Circulation of medical records
Medical staff in clinical departments and other medical technical departments borrow and return medical records. Through the unified identification of RFID on medical records, enter the borrowing department, borrowers, and related borrowing reasons, and the system automatically generates medical record borrowing and return records.
2.6 Reminder of overdue medical records
The medical record is not archived to the medical record room when discharged from the hospital, three days for inpatients, seven days for dead patients, the medical record tracking system connected to the RFID background computer port is set to indicate that the medical record is not archived. If the medical record has not been archived to the medical record room after the specified time limit, the clinical department doctor logs in After the doctor’s workstation, the system will pop up a reminder message that the medical record is not archived, and the medical record administrator will also pop up a reminder message when logging in to the tracking system; to borrow the medical record, set a reminder to return for a week, if the medical record is not returned to the medical record room beyond the set date, borrow When the manager of the medical record logs into the medical record tracking system, the system will pop up a non-return reminder message to facilitate the medical record manager to read out the borrower’s return of the medical record in time.
3. The advantages of enabling RFID technology-based tracer management throughout the entire medical record
3.1 Improve work efficiency
Before the emergence of QR code and RFID technology, medical record administrators needed to perform complicated manual registration for medical record recovery, filing, borrowing, and return. They also needed to read the cumbersome medical record borrowing records during verification. After the emergence of QR code scanning technology, although Manual operation is no longer required, but it is also necessary to scan the barcode on the first page of the medical record one by one. Now the RFID reader can read all medical record identification information at one time, and as long as the medical record exists in the space where the reader is installed, regardless of whether the medical record is currently in any stage of circulation, the administrator can accurately query the specific medical record. Location, shorten the time of manual inquiry, and “liberate” the staff from the cumbersome labor force, and improve the work efficiency.
3.2 Expand storage capacity
After using RFID electronic tag technology, the tag can store several megabytes of information, and the storage capacity is greatly increased compared with manual input information and two-dimensional code technology. This solves the problem of manual registration requiring a large amount of paper resources and greatly saves manpower and material resources. Cost; At the same time, it solves the problem of the limited amount of information stored by the QR code scanning technology. The disease manager arranges the location of the RFID reader in each workflow office, and can realize the non-contact, multi-quantity collection of file information.
3.3 Increase security
RFID electronic tags use RFID tag readers to repeatedly erase and write information that has been encrypted in a variety of ways. The information must also be read with a key to decrypt it. Therefore, this type of electronic tag has a high degree of information security and is difficult to copy. Moreover, its identification work does not require manual intervention and can work in various harsh environments, which also greatly improves its use safety. The security of medical records is the key content in the management of medical records. The encryption function of RFID technology prevents the danger of possible tampering of medical record trace information.
3.4 Realize digital management
When the RFID tag is attached to the medical record, the information such as the location and status of the medical record (whether it has been lent) can be displayed in the system in real time, which is convenient for accurately distinguishing which medical record is in the process of recovery, coding, quality control, filing, feedback, and lending. It can directly determine the time of medical record collection, whether it is overdue, the filing time, and whether it is overdue to archive records, etc., so that the medical record can be circulated within a certain controllable range, to ensure the precise positioning of the medical record circulation, and to maintain the availability of the medical record. With the introduction of high-tech technologies, the traditional management mode of paper archives has been changed, the efficiency of traditional medical record management has been improved, and the work loopholes that may be brought about by the traditional mode have been avoided to a large extent, and the management of medical records has been realized. Digital management.
4. Problems in the application of RFID technology
4.1 High cost
At present, the cost of the widely used barcodes ranges from 0.04 to 0.4 yuan, and most hospitals can print barcodes directly on the front page of medical records, so the cost is not high. However, the cost of each RFID tag ranges from 2-4 yuan, and it is also necessary to purchase a large number of RFID readers and back-end computers or connection port software. Therefore, if RFID technology is popularized in medical record management in the future, it will need to rely on large-scale usage to reduce costs; and RFID technology not only solves the hardware cost, but also includes the corresponding software system cost, which is difficult for a single medical record room to bear.
4.2 Standards are not unified
At present, the global standard of RFID technology has not yet been unified, which is also one of the important reasons why it is difficult to use uniformly in hospitals across the country, which affects its development to a certain extent.
5. Summary
RFID technology has many advantages, but in actual use, there are still implementation obstacles such as high cost and ununified standards that need to be resolved. However, it has superiority that other methods cannot match and is an inevitable trend of intelligent development. RFID technology enables the whole-process tracking system of medical records to not only manage and monitor the circulation of medical records, but also to accurately locate the medical records in the circulation process. Through statistical calculations, key data that can intuitively reflect work efficiency can be calculated, which promotes The effective use of human resources greatly improves the management level and efficiency of the hospital. The whole-process trace management of medical records based on RFID technology not only optimizes the work process, reduces intermediate links, improves work efficiency, and promotes the scientific, standardized, and refined medical record management, but also plays a positive role in promoting the construction of digital hospitals.
