Outpatient infusion work is busy, trivial, and the work repeatability is strong and lacks new ideas. Infusion patients are numerous and miscellaneous, and the types of drugs used are numerous and new. Nurses do not understand new drugs and increase the insecurity of outpatient infusion. The competition in the medical market and the increased self-maintaining awareness of patients require that the outpatient infusion work be safer and more efficient. How to eliminate hidden dangers of outpatient transfusion and provide patients with safe and quality services is a new topic faced by medical administrators.
The system is committed to ensuring the safety of patient infusion, improving the noisy environment of the infusion room, maintaining the order of infusion sites, reducing the work pressure of nurses, and reducing the conflicts between doctors and patients, and creating a new standard of high-standard, high-quality new infusion care services.
The mobile outpatient transfusion management system infusion patient first arrives at the infusion center's help desk. The drug, infusion bag (with bar code label or RFID tag) is handed to the nurse. Before the nurse prints the infusion label, the PDA scans the medicine bag and the infusion seat card. Barcode, confirm the patient's identity and infusion seat information, print the infusion label, (patient name, medication, infusion seat number, etc.). The patient receives the infusion seat card from the nurse with an invoice, etc., goes to the prescribed infusion seat, and waits for the nurse's service.
The nurse configures the liquid according to regulations (completed in the relatively clean room) and places it in an infusion nurse. The nurse first uses the PDA to scan the medicine bag, seat number information, and the infusion seat card on the patient's body. The nurse started infusing the patient. At the same time, information such as the time of infusion operation service and the operator was recorded.
When the patient needs help, they can press the wireless button (located on the side of the chair of the infusion chair or other misadjustable position), and there is a warning light. Request service information through the wireless network, the PDA busy on the work of the nurse's wrist will send a prompt tone and display a certain seat number, patient information, infusion information and other requests for help, the nurse rushed to solve the infusion patient's request, Or transfer to other nurses for help. After the infusion is over, the system can automatically disassociate the patient from the seat number and facilitate the reception of the next patient.
The use of the system process and the hospital's original main line of the process, including the patient's drug, nurse dispensing, nurse infusion to the patient, the patient calls the nurse needs help and other links. However, the use of the system in most aspects of the use of clinical medical assistants handheld terminals and bar code technology to change and improve the original operation of the hospital process links.
include:
When pharmacists give drugs and prescriptions to patients, they use bar code printers to print two-dimensional bar codes and bar codes to digitize infusion information.
When the patient reaches the nurse workstation with the drug and the prescription (with 2D barcode attached), the nurse at the nurse workstation uses a 2D barcode scanner to extract the 2D barcode on the patient's prescription and extract information to generate the source data of the system.
The bar code printer at the nurse workstation prints three types of barcodes, one on the infusion sheet for easy post-mortem verification; one on the infusion bag for easy checking during the infusion process; and the other one is attached to the patient using a sticker. Record the patient's name, date of birth, location, and other information, to facilitate the digital verification of the patient's identity, avoiding the mixed with the patient of the same name.
When the nurse injects the patient, the hand-held terminal is used to scan the barcode of the infusion bag and the bar code on the patient, and the two information are matched. Use information matching as a prerequisite for infusion operations.
When the patient is unresponsive and needs help, he uses the help button of the wireless call unit to call the nurse. At this time, the nurse's hand-held terminal displays information such as seat number, bearing, and patient's name that need to help the patient so that the nurse can promptly reach the patient. Give help around.
When the patient needs to take a bottle or pull a needle, the nurse is called by using the button of the RFID wireless call unit. At this time, the nurse's handheld terminal displays the seat number, position, patient's name, and drug name of the patient currently undergoing infusion service. The information on the name of the next infusion drug, etc., nurses can first take drugs at the nurse's station, and then go to the patient to check the receiving bottle. It is not necessary to first go to the patient to understand the patient information, and then take the drug H process, which saves a lot of time for the nurse and reduces the work intensity of the nurse.
When the nurse carries out the bottle-receiving operation, it is necessary to use a hand-held terminal to scan the barcode of the infusion bag and the bar code on the patient, and then the bottle-receiving operation can be performed under the condition that the two information are matched, which can greatly reduce the work pressure of the nurse.
After the infusion is over, the system automatically prints the infusion results and saves the file for easy reference.
Wireless mobile clinic infusion system advanced
Comparing the two processes, the wireless mobile outpatient infusion system embodies the following advances:
The use of barcodes instead of manual verification to achieve the electronic information of infusion information with bar code information to ensure the correct matching of drug information and patient information, reduce medical errors, and ensure the safety of patients.
The patient's identity and infusion seat number are identified on the patient's 2D barcode. It not only ensures the hospital's infusion position and plan order, but also helps nurses find the timeliness and accuracy of the patient when they are serving.
Combining mobile computing technology and mobile identification technology to give patients a humanized service not only enhances hospital informationization, but also enhances the hospital's social reputation.
The handheld terminal carried by the nurse can receive the patient's call information anytime and anywhere to ensure the high quality of services and the quiet environment.
Managers can assess the workload and quality of nurses through system-generated reports, including the number of patients to perform, scans for secondary errors, and error records.
System Feasibility Analysis and Demonstration
1, compared with other management systems There are some outpatient management systems on the market today, such as queuing allocation of seat systems, call systems and so on. However, systems are often isolated, information and services cannot be shared, and the infusion safety link cannot be guaranteed. Moreover, products are generally not well-known and have poor reliability. The use of bar code, RFID, wireless network and PDA development technologies to organically integrate various subsystems or links in hospital outpatient management to achieve a reliable, advanced, and innovative system that truly brings convenience and practicality to hospital outpatient transfusion management. , will inevitably become a bright spot in hospital information construction.
2. Technical feasibility The system uses WLAN, RFID, and LAN technologies as the transmission platform of the entire system and is responsible for data stream transmission between front-end application devices such as PDAs, call units, nurse workstations, and back-end databases, realizing real-time communication between the application and background. Complete input, call, performance and other links.
The HIS system opens the interface and uses standard protocol interfaces to customize nurse workstations, database servers, and PDA software.
3, the cost of the number of equipment can be based on the hospital's actual environment and demand for scientific configuration, such a large-scale capital investment will not bring a great burden on the hospital.
4. System Benefits Through the construction of this outpatient infusion system, the following benefits will be directly brought to the hospital:
The use of barcodes instead of manual verification to achieve the electronic information of infusion information with bar code information to ensure the correct matching of drug information and patient information, reduce medical errors, and ensure the safety of patients.
The patient's identity and infusion seat number are identified on the patient's 2D barcode. It not only ensures the hospital's infusion position and plan order, but also helps the nurse to find the timeliness and accuracy of the patient while serving.
Combining mobile computing technology and mobile identification technology to give patients a humanized service not only enhances hospital informationization, but also enhances the hospital's social reputation.
The handheld terminal carried by the nurse can receive the patient's call information anytime and anywhere to ensure the high quality of services and the quiet environment.
Managers can assess the workload and quality of nurses through system-generated reports, including the number of patients to perform, scans for secondary errors, and error records.
The contribution of the outpatient infusion system to the hospital cannot be defined and expressed simply by numbers, but it virtually creates value for the hospital. The hospital's outpatient management efficiency and social reputation have been directly improved, which has improved the economic benefits of the hospital.
