Infinite radio frequency identification technology (Radio Frequency Identification, RFID) is a non-contact automatic identification technology, mainly by identifying the radio frequency signal attached to the article to identify the target article and obtain relevant data. RFID technology has gradually played an important role in many industries. Nowadays, medical reform is deepening day by day, and high-tech hospital management models are gradually formed. Therefore, the application of RFID technology in the field of medical records management has become an inevitable trend, which has brought the era of digital medical records management.
The whole process of medical records tracking management is an inevitable trend in the development of medical records management in the information age and an important stage of digitization of medical records. The introduction of RFID technology for the whole process of medical records tracking management can not only achieve a scientific and efficient management mode, Can save manpower and material costs. Tracking the entire process of medical records based on RFID technology is to introduce computer technology, network technology and RFID technology into the flow control process of medical records, identify the uniqueness of each medical record, and use RFID technology to connect all aspects of medical record management, not only to achieve The purpose of each medical record can be accurately traced, and the real-time status information of the medical records can be quickly queried.
1 RFID technology background
RFID technology is a comprehensive self-identification technology based on carrier, coding, identification, communication and other technologies. RFID technology is mainly a non-contact information transfer using the spatial coupling of radio frequency signals. Different items can transfer different information to achieve automatic identification. Compared with other similar technologies, RFID technology has the characteristics of large storage capacity, fast read rate, long read and write distance, strong penetration, long service life, and good environmental adaptability. An RFID system should have three basic components, an RFID tag, several RFID readers, and a back-end computer. The RFID tag is attached to the object and sends out a radio frequency signal. The RFID reader realizes the collection and return of the tag information. The read information is transmitted to the background computer. The background computer analyzes the transmitted information and manages the normal operation of the entire label system. The RFID technology is applied to the medical record tracking system, mainly by attaching electronic tags to each medical record, installing readers in the clinical department and the various departments of the medical record room, and connecting the back-end computer to the medical record tracking system port. Managers can accurately check the status and location of the medical record process through the tracer system to confirm the filing time.
2 Tracking application of medical records based on RFID technology
2.1 Medical Record Recovery
After each medical record of the department passed the first-level quality control of the department, the general affairs nurse attached the RFID electronic tag and sent it to the medical record room from the property. The medical records are sent to a medical records recovery room equipped with an RFID reader. The medical records manager registers the recovered medical records and compares them with the patient information of the hospital on the same day to obtain the list of undocumented medical records and the location of the department where the medical records are located. After the recovery is completed, the administrator can uniformly identify the medical record information in the medical record tracking system as an archived state.
2.2 Disease coding
After the medical records are recovered, the staff of the coding team will carry out disease coding. Install an RFID reader near the office or office computer of the coding team. When the coder files the medical records to the scope of the work site, the RFID reader can not only trace the medical records into the disease catalogue link, but even the specific location. The coder recognizes by ID and judges whether the medical records that need to be cataloged that day have been filed in the medical record room, so as to effectively supervise the medical records in a timely manner. After the coder’s cataloging is completed, the medical record status can be identified as a coded status in one click.
2.3 Medical Record Quality Control
The coder transfers the coded medical records to the quality control personnel. The medical records pass through the quality control office with a reader. The quality control personnel can first check whether the transferred medical records match the number of medical records in the hospital on the same day. Location and work status, then perform quality control work on the medical record, and identify the medical record status information.
2.4 Medical Record Feedback
After finishing and binding the medical records, some medical records need to be placed in the feedback cabinet of the medical record reading room due to missing signatures, missing items, etc. The medical records manager can form a circulation record of the feedback medical records through the RFID reader installed in the reading room. Since the feedback of medical records requires rectification by clinical medical personnel, it is easy to be taken to the reading room or even outside the medical record room. The medical records management staff can monitor the feedback of the medical records when they are taken out of the reading room through the background data in order to find out the whereabouts of the medical records.
2.5 Medical Record Circulation
Medical personnel of clinical departments and other medical technology departments borrow and return medical records. Through the unified identification of RFID on medical records, they are entered into the borrowing department, borrowers, and related reasons for borrowing, and the system automatically generates records of borrowing and returning medical records.
2.6 Reminder of medical records overdue
When the medical records of the hospital were not filed in the medical record room, three days for inpatients and seven days for dead patients, the medical record tracking system connected to the RFID back-end computer port was set to be filed without reminding. After the doctor’s workstation, the system will pop up the reminder message of undocumented medical records. The reminder will also pop up when the administrator logs on the tracking system. Borrow the medical records and set a reminder for the week. If the medical records are not returned to the medical records room after the set date, borrow When a medical record manager 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 a timely manner.
3. Enabling Advantages of RFID-based Whole-process Trace Management
3.1 Improve work efficiency
Before the emergence of QR code and RFID technology, medical records administrators had to perform tedious manual registration when recovering, archiving, borrowing, and returning medical records. They also needed to read the tedious records of borrowing medical records during verification. After the emergence of QR code scanning technology, although No manual operation is needed, but you also need to scan the barcode on the first page of the medical record one by one. Now RFID readers can read all the medical record identification information at once, and as long as the medical records exist in the space where the readers are installed, no matter whether this medical record now belongs to any stage in circulation, the administrator can accurately query the specifics of the medical records. Location, which shortens the time of manual inquiry, and “frees up” staff from tedious labor, improving work efficiency.
3.2 Expansion of storage
After the use of RFID electronic tag technology, the tag can store megabytes of information, and the storage capacity has increased significantly compared to manual entry of information and two-dimensional code technology. Cost; at the same time solved the problem of limited information storage by two-dimensional code scanning technology. The position of the RFID reader is arranged by the disease manager in each workflow office, which can realize non-contact and large-scale collection of archive information.
3.3 increase security
RFID electronic tags use RFID tag readers to repeatedly erase and encrypt information that has been encrypted in a variety of ways. Reading information also requires a key to decrypt it. Therefore, this type of electronic tag information is highly secure and difficult to copy. And its identification work does not require manual intervention and can work in various harsh environments, which also greatly improves its use safety. Medical record security is an important part of medical record management. The encryption function of RFID technology prevents the danger that the medical record tracking information may be tampered with.
3.4 Digital Management
When an RFID tag is attached to a medical record, information such as the position and status of the medical record (whether it is loaned out) can be displayed in the system in real time, making it easy to accurately determine which of the medical records is in recovery, coding, quality control, filing, feedback, and lending. Process, and can directly determine the recovery time of medical records, whether it is overdue, archiving time, and whether the archival records are overdue, so that the medical records can be circulated within a certain controllable range to ensure the accurate positioning of the medical records circulation and maintain the availability of medical records. With the introduction of high-tech technology, the management mode of traditional paper records has been changed, the work efficiency of traditional medical records management has been improved, and the work loopholes that traditional models may bring have been largely avoided, and the Digital management.
4 Problems in RFID Technology Application
4.1 High cost
Currently widely used barcodes, each costing between 0.04-0.4 yuan, and most hospitals can print the barcode directly on the first page of the medical record, so the cost is not high. However, the cost of each RFID tag ranges from 2-4 yuan, and a large number of RFID readers and back-end computers or connection port software need to be purchased. Therefore, if RFID technology is to be widely used in medical record management in the future, it will need to rely on large-scale usage to reduce costs; and in addition to solving hardware costs, RFID technology also includes corresponding software system costs. These funds are difficult for individual medical records to implement.
4.2 Standards are not uniform
At present, the global standard of RFID technology has not been unified, and it is also one of the important reasons that it is difficult to use it uniformly in hospitals across the country, which has affected its development to a certain extent.
RFID technology has many advantages, but in actual use, there are still implementation obstacles such as high cost and non-uniform standards to be resolved, but it has incomparable advantages in other ways, which is an inevitable trend of intelligent development. RFID technology enables the whole process of medical record tracking system not only to achieve the management and monitoring of various circulation links of the medical records, but also to accurately locate the medical records in the circulation process, through statistical calculation to calculate key data that can directly reflect the efficiency of work, and promoted The effective use of human resources has greatly improved the management level and efficiency of the hospital. The whole process of medical record tracking management based on RFID technology not only optimizes the work flow, reduces the intermediate links, improves the work efficiency, promotes the scientific, standardized and refined medical record management, but also plays a positive role in promoting the construction of digital hospitals.
