As the forefront of the hospital, the outpatient infusion room receives a large number of patients and their families every day. It is a place where the population is relatively concentrated and mobile, and it is also an important part of nursing management.
The outpatient infusion work is busy, trivial, repetitive and lack of novelty. However, there are many and complicated infusion patients, the types of drugs used are many and new, and the nurses do not understand the new drugs, etc., which increase the unsafe factors of outpatient infusion. The competition in the medical market has increased patients’ awareness of self-maintenance, which requires safer and more efficient infusion work in outpatient clinics. How to eliminate the unsafe hidden dangers of outpatient infusion and provide patients with safe and high-quality services is a new issue for medical managers.
The wireless infusion system developed based on RFID technology is dedicated to ensuring the safety of patient infusion, improving the noisy environment of the infusion room, maintaining the order of the infusion place, reducing the work pressure of nurses, reducing the contradiction between doctors and patients, and creating a high-standard, high-quality new infusion nursing service New model.
Infusion management system Infusion patients first go to the service desk of the infusion center, and hand the medicine and infusion bag (printed with a barcode label or RFID tag) to the nurse. Before printing the infusion label, the nurse scans the barcode on the medicine bag and the infusion seat plate with a PDA. Confirm the patient’s identity and infusion seat information, and print the infusion label (patient name, medication, infusion seat number, etc.). The patient obtains the infusion seat card from the nursing staff by presenting the invoice, and then goes to the prescribed infusion seat to wait for the nurse’s service.
The nurse configures the liquid according to the regulations (completed in a relatively clean configuration room), puts the label on it and gives it to the infusion nurse. The nurse uses the PDA to scan the medicine bag, seat number information and the patient’s infusion seat card, and confirm that it is correct. The nurse began to infuse the patient. At the same time, the time point of the infusion operation service, the operator and other information are recorded.
When the patient needs help, he can press the wireless button by himself (located on the side of the armrest of the infusion chair or other position that is not easy to be triggered by mistake), and there is a reminder light. The service request information is through the wireless network, and the PDA on the wrist of the nurse who is busy with the work will sound a prompt tone and display a certain seat number, patient information, infusion information, etc., asking for help. The nurse rushed to solve the infusion patient’s request in time. Or refer to other nurses for assistance. After the infusion, the system can automatically unbind the patient and the seat number to facilitate the reception of the next patient.
The process of using this system is the same as the main line of the original process in the hospital, including the steps of patient extracting medicine, nurse dispensing medicine, nurse giving patient infusion, and patient calling nurse for help. However, the use of this system has used clinical medical assistant hand-held terminals and barcode technology in most aspects to change and improve the operation methods in the original process links of the hospital.
include:
· When pharmacists give patients medicines and prescriptions, they use a barcode printer to print a two-dimensional barcode, and realize the electronic infusion information by means of barcode.
· When the patient arrives at the nurse workstation with the medicine and prescription (with a two-dimensional barcode), the nurse at the nurse workstation uses a two-dimensional barcode scanner to extract the information from the two-dimensional barcode on the patient’s prescription to generate the source data of the system.
· The barcode printer of the nurse workstation prints three types of barcodes, one is pasted on the infusion sheet for easy checking afterwards; the other is pasted on the infusion bag for checking during the infusion process; the other is pasted on the patient with self-adhesive , Record the patient’s name, date of birth, location and other information to facilitate the digital verification of the patient’s identity and avoid the confusion of patients with the same name.
· When nurses infusion of patients, they use the handheld terminal to scan the barcode of the infusion bag and the barcode on the patient’s body, and the two information is matched. Use information matching as a prerequisite for infusion operations.
· When the patient has an unsuitable reaction and needs help, he can use the help button of the wireless call unit to call the nurse. At this time, the nurse’s handheld terminal displays the seat number, location, patient name and other information of the patient who needs help, so that the nurse can arrive in time The patient is there to help.
· When the patient needs to receive the bottle or withdraw the needle, use the bottle-receiving button of the RFID wireless call unit to call the nurse. At this time, the nurse’s handheld terminal displays the seat number, location, patient name, and the drug currently infusion of the patient who needs to receive the bottle. For information such as the name and the name of the next bottle of infusion medicine, the nurse can first pick up the medicine at the nurse’s station, and then go to the patient to check the bottle. There is no need to go to the patient’s side to learn about the patient’s information before taking the medicine H, which saves a lot of time for the nurse and reduces the work intensity of the nurse.
· The nurse needs to scan the barcode of the infusion bag and the barcode on the patient with the handheld terminal when receiving the bottle. Only when the two information match, the bottle can be connected, which can greatly reduce the nurse’s work pressure.
· After the infusion, the system automatically prints the infusion result sheet and archives it, which is convenient for the hospital to inquire in the future.
Advancement of wireless mobile outpatient infusion system
Through the comparison of the two processes, the wireless mobile outpatient infusion system embodies the following advanced features:
· Use bar code instead of manual check, realize the electronic infusion information with bar code information, ensure the correct matching of drug information and patient information, reduce medical errors, and ensure the safety of patients.
· Use the two-dimensional bar code on the patient to confirm the patient’s identity and infusion seat number and other information. It not only ensures the orderly arrangement and plan of the hospital’s infusion location, but also helps the nurses to find the patient’s timeliness and accuracy when serving.
· Combining mobile computing technology and mobile recognition technology to provide patients with a humanized service, which not only improves the hospital’s information construction, but also improves the hospital’s social reputation.
· The hand-held terminal carried by the nurse can receive the call information of the patient anytime and anywhere, ensuring the high quality of the service and the quiet environment.
· Managers can evaluate the workload and quality of nurses through the reports generated by the system, including the number of patients executed, the number of scans, and the record of errors.
System feasibility analysis and demonstration
1. Comparison with other management systems
Nowadays, there are some outpatient management systems on the market, such as queue allocation system, call system and so on. However, the systems are often isolated, information and business cannot be shared, the infusion safety link cannot be guaranteed, and the products generally have low reputation and poor reliability. Use bar code, RFID, wireless network and PDA development and other technologies to organically integrate the various subsystems or links of hospital outpatient management to achieve a reliable, advanced and innovative system, which indeed brings convenience and practicality to hospital outpatient infusion management , It will definitely become a bright spot of hospital informatization construction.
2. Technical feasibility
The system uses WLAN, RFID and LAN technology as the transmission platform of the entire system, responsible for the data stream transmission between the front-end application equipment such as PDA, call unit, nurse workstation and the back-end database, realizes the real-time communication between the application and the back-end, and completes the entry and call , Performance and other links.
The HIS system has open interfaces and uses standard protocol interfaces to realize the customization of nurse workstations, database servers, and PDA software.
3. Cost feasibility
The number of equipment can be configured scientifically according to the actual environment and needs of the hospital, and such a scale of capital investment will not bring a great burden to the hospital.
4. System benefits
The construction of this outpatient infusion system directly brings the following benefits to the hospital:
· Use bar code instead of manual check, realize the electronic infusion information with bar code information, ensure the correct matching of drug information and patient information, reduce medical errors, and ensure the safety of patients.
· Use the two-dimensional bar code on the patient to confirm the patient’s identity and infusion seat number and other information. It not only ensures the orderly arrangement and plan of the hospital’s infusion location, but also helps the nurses to find the patient’s timeliness and accuracy when serving.
· Combining mobile computing technology and mobile recognition technology to provide patients with a humanized service, which not only improves the hospital’s information construction, but also improves the hospital’s social reputation.
· The hand-held terminal carried by the nurse can receive the call information of the patient anytime and anywhere, ensuring the high quality of the service and the quiet environment.
· Managers can evaluate the workload and quality of nurses through the reports generated by the system, including the number of patients executed, the number of scans, and the record of errors.
The contribution of the outpatient infusion system to the hospital cannot be simply defined and represented by numbers, but it creates value for the hospital invisibly. Directly improve the hospital outpatient management efficiency and social reputation, thereby improving the economic benefits of the hospital.
