Radio Frequency Identification (RFID) is a non-contact automatic identification technology that mainly identifies target items and obtains relevant data by identifying radio frequency signals attached to items. RFID technology has gradually played an important role in many industries. Nowadays, medical reform is deepening day by day, and Hospital management models with high technical level are gradually taking shape. Therefore, applying RFID technology to the field of medical record management has become an inevitable trend, bringing about the era of digital management of medical records.

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 digitization of medical records. The introduction of RFID technology into the whole-process tracer management of medical records can not only achieve a scientific and efficient management model, but also Can save labor and material costs. The whole process tracing of medical records 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 track 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, encoding, 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 rate, long reading and writing distance, strong penetration, long service life, and good environmental adaptability. The RFID system should have three basic components, RFID tags, several RFID Readers and a backend computer. The RFID tag adheres to the object and emits a radio frequency signal. The RFID reader collects the tag information and transmits the data back. The read information is transmitted to the background computer. The background computer analyzes the transmitted information and manages the normal operation of the entire tag system. Applying RFID technology to the medical record tracking system mainly involves attaching electronic tags to each medical record, installing readers at the locations used by various departments in clinical departments and medical record rooms, and connecting the backend 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. Full-process tracking application of medical records based on RFID technology

2.1 Medical record recycling

After each medical record discharged from the department on the same day has passed the department's first-level quality control, the general nurse attaches an RFID electronic tag and then the property management department sends it to the medical record room. The medical records are sent to the medical record recovery room equipped with an RFID reader. The medical record administrator registers the recovered medical records and compares them with the information of discharged patients on the day to obtain a list of unFiled medical records and the location of the department where the medical records are located. 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 coding

After the medical records are recovered, the staff of the coding team will perform disease coding. Install an RFID reader in the coding team's office or next to the office computer. When the coder files the medical records within the workplace, the RFID reader can not only trace that the medical records have entered the disease cataloging stage, but can even trace them to the specific location. The coder uses ID identification to determine whether the medical records to be cataloged that day have been filed in the medical records room, so as to effectively supervise the department's timely filing of medical records. After the coder completes the cataloging, he can uniformly mark the medical record status as coded with one click.

2.3 Medical record quality control

The coder hands over the coded medical records to the quality controller, and the medical records pass through the quality control office equipped with a reader. The quality controller can first check whether the transferred medical records match the number of discharged medical records on the day. If they do not match, the medical records can be queried through the tracer system. location and working status, and then perform quality control on the medical records and mark the status information of the medical records.

2.4 Medical record feedback

After the medical records are organized and bound, some medical records need to be put into the feedback cabinet in the medical record reading room due to missing signatures, missing items, etc. The medical record administrator can form a circulation record of the feedback medical records through the RFID reader installed in the reading room. Since feedback medical records require correction by clinical medical staff and are easily taken to the reading room or even places outside the medical record room, medical record management personnel can use background data to monitor when the feedback medical records are taken out of the reading room in order to find the whereabouts of the medical records.

2.5 Circulation of medical records

When medical staff in clinical departments and other medical technology departments borrow and return medical records, through unified identification of RFID on medical records, the borrowing department, borrowing personnel, and relevant borrowing reasons are entered, and the system automatically generates records of borrowing and returning medical records.

2.6 Reminder of overdue medical records

The discharged medical records on the same day are not archived in the medical records room. Three days for inpatients and seven days for deceased patients. Set the unfiled prompt on the medical record tracking system connected to the RFID backend computer port. If the medical records have not been archived in the medical records room after the specified period, the clinical department doctor logs in. After the doctor's Library-borrowing-machine-touch-query-intelligent-terminal-all-in-one-machine.html target='_blank'>workstation, the system will pop up a reminder message that the medical record is not archived. When the medical record administrator logs in to the tracer system, a reminder message will also pop up. To borrow a medical record, set a reminder to return it within one week. If the medical record is not returned to the medical record room after the set date, the loan When the manager of a medical record logs in to the medical record tracking system, the system will pop up a reminder message for unreturned medical records to facilitate the medical record administrator to read out the returned medical records of the borrower in a timely manner.

3. Advantages of enabling full-process tracer management of medical records based on RFID technology

3.1 Improve work efficiency

Before the emergence of QR code and RFID technology, medical record administrators needed to perform complicated manual registration when collecting, archiving, borrowing, and returning medical records. They also needed to read complicated medical record borrowing records during verification. After the emergence of QR code scanning technology, although Manual operations are no longer required, but the barcode on the home page of the medical record needs to be scanned one by one. Now the RFID reader can read all the medical record identification information at one time, and as long as the medical record exists in the space where the reader is installed, the administrator can accurately query the specific information of the medical record no matter what stage it is in circulation. location, shortening the time of manual inquiry, "liberating" staff from tedious labor, and improving work efficiency.

3.2 Expand storage capacity

After using RFID electronic label technology, the label can Store several megabytes of information. The storage capacity is significantly larger than that of manually entered information and QR code technology. It 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 limited information storage in QR code scanning technology. The patient administrator arranges the positions of RFID readers in each workflow office to achieve non-contact and large-scale collection of file information.

3.3 Increase security

RFID electronic tags use RFID tag readers and writers to repeatedly erase and write information that has been encrypted in a variety of ways. Reading information requires a key to decrypt it. Therefore, this kind of electronic tag information is highly secure and difficult to copy. Moreover, its identification work does not require manual intervention and can work in various harsh environments, which also greatly improves its safety of use. The security of medical records is a key issue in medical record management. The encryption function of RFID technology can well prevent the risk of tampering with tracer information of medical records.

3.4 Realize digital management

When RFID tags are attached to medical records, information such as the location and status of the medical records (whether they have been loaned out) can be displayed in the system in real time, making it easy to accurately determine which stage of recovery, coding, quality control, archiving, feedback, and borrowing the medical records are. process, and can directly determine the medical record recovery time, whether it is overdue recovery, archiving time and whether it is overdue archiving records, etc., so that medical records can be circulated within a certain controllable range, ensuring the precise positioning of medical record circulation and maintaining the availability of medical records. With the introduction of high-tech technology, the management model of traditional paper file records has been changed, the work efficiency of traditional medical record management has been improved, and the work loopholes that may have been caused by the traditional model have been avoided to a large extent, and the management of medical records has been realized. Digital management.

5. Summary
