The advantages of using intelligent logistics system in hospital lean management
In the context of a market economy, medical and health services are not immune to the market economy. Competition between hospitals exists not only at the level of medical technology and medical research, but also at the level of hospital management. The role of hospital's lean management in the development of hospitals is becoming more and more obvious, which has drawn great attention from hospital managers. In recent years, major hospitals in China have also begun to attach importance to the management of hospital logistics systems. In terms of hospital supplies and supply, service quality and management, they have begun to learn international advanced management concepts, improve the overall image of the hospital, and improve the management of the entire hospital. Efficiency and promote the development of medical and health services.
1. Development history of hospital lean management
Experience management: From 1919 to 1945, managers consciously organized activities. With management and supervision personnel and systems, they initially formed standards, methods, and systems, but there was no complete management organization system and no systematic theoretical analysis methods to guide practice.
Statistical management: From 1950 to 1970, with the rapid development of enterprise management methods, quantitative analysis technology was widely used in hospital management. With sound quality management institutions and organizational systems, quality supervisors, a large number of industrial management models and theories were adopted. .
Quality management: From 1970 to 1990, in 1961, American quality management expert Fiegen Paulo put forward the concept of total quality management-the concept of TQM, which was quickly accepted by the business community. It was applied to hospital management in the 1970s, but the effect of TQM in practical application was not satisfactory.
Lean management: From 1990 to the present, since the 1980s, research on Toyota's production method TPS has been carried out around the world, and the concept of lean production was first proposed.
As an emerging industry, the hospital's intelligent logistics system is increasingly demanding for the accuracy of medical service quality. Supported by high-tech and advanced management concepts, it can reduce operating costs, improve the level of medical services, and ensure service quality. The role of management. The hospital's lean management should adopt an intelligent logistics system. With the help of intelligent logistics transmission equipment, the hospital can accurately and safely transport various types of items in the hospital to be transported between departments. There is no need for workers to push the goods during transportation. Control, real-time monitoring of the entire system operation status, transportation records can be saved, retrieved, and can also provide remote diagnosis.
At present, the status of logistics in most hospitals is: delivery personnel + trolleys + elevators . This logistics method has obvious disadvantages and does not meet the requirements of modern hospitals. With the emergence of various types of logistics transmission systems in recent years, its obvious advantages such as high efficiency, reliability, and non-stop have been recognized and accepted by more and more hospital leaders.
Developed countries and regions have earlier used logistics transmission systems in various fields. Most of the medium-sized hospitals in the United States, Germany, Japan, and Singapore are equipped with logistics transmission systems. China introduced the pneumatic pipeline logistics transmission system at the end of the 1980s. Due to many problems such as technology, capital, and personnel, it has not been promoted. In the past ten years, the number of hospitals used has gradually increased, but the relative proportion is still low, and the variety of applications is relatively single, mainly using pneumatic logistics or rail cars.
In recent years, intelligent logistics transmission systems have been valued and adopted by more and more hospitals for their advantages such as high efficiency, convenience, accuracy, reduction of human resource costs, and improvement of hospital management. Choosing an intelligent logistics transmission system suitable for the actual situation of each hospital has obvious practical value for improving work efficiency, reducing overall costs, improving overall hospital operation and maintenance efficiency, and improving hospital competitiveness.
The logistics system supporting the hospital's lean management should have the following characteristics:
The products are diverse and meet the transportation of different types of goods; the subsystems need to be connected to form a system; the products are highly intelligent and automated, and the operation efficiency is high; the operation is convenient, the maintenance is convenient, and the operation cost is saved.
In view of the requirements of the above-mentioned hospitals for lean management of logistics systems, a highly intelligent logistics system is indispensable in the construction and operation of large-scale comprehensive medical buildings.
Features of modern intelligent logistics system:
High operating efficiency: Compared with manual operation, the transportation time plan has been optimized, and the stability of material delivery has been improved. The time schedule has been implemented and plans for different time periods have been guaranteed.
Low operation and maintenance costs: Intelligent logistics systems can effectively reduce traditional damage to equipment. Repair costs and maintenance costs of building structures have also been significantly reduced.
Traceability of the transportation process: The traceability of the shipment is guaranteed, and the process table between the cargo destination and the replenishment stage is automatically stored, and even the process table between the departure from the production area is realized to achieve full traceability.
Reduce the possibility of noise and pollution during transportation: The transmission process is in the hoistway or ceiling, which reduces the external impact of noise on the environment. At the same time, closed transportation management measures reduce the risk of pollution that may occur during transportation.
Short return on investment cycle: The reduction in daily operating costs and subsequent maintenance costs means that the initial construction investment costs will be recovered soon.
Ensuring safety in the transportation process: The automated transportation process and hidden transportation routes minimize the risks to personnel during the transportation process. In case of emergencies, they do not occupy the escape route.
Improve patient satisfaction: Through automation, medical staff is freed from logistics tasks, focusing on patient needs. During the transportation process, there is no need to enter the ward, so that the privacy of patients and their families is protected.
Improve the intelligence level of the hospital and enhance the brand effect of the hospital: The use of intelligent logistics systems can enhance the level of intelligent management of the hospital and enhance the brand effect of the hospital.
