The hospital business is uninterrupted for 7*24 hours. In today's rapid development of hospital technology, leaving the support of information systems and medical equipment, the hospital business will be rampant. Therefore, it is a necessary condition to ensure the continuous and stable operation of the hospital business - to ensure the hospital's power supply. Recently, Fang Qiang, deputy dean of the Logistics Management Research Institute of Fudan Hospital, Yves Renaud, Global Marketing Director of Schneider Electric, and Qu Yujuan, Marketing Director of Schneider Electric China's digital energy efficiency business, accepted HC3i interviews on the outstanding problems of current hospital energy management.

According to Yves Renaud, Schneider Electric's global medical industry marketing director, “As the population grows, hospital energy consumption begins to surge and needs to control electricity spending.†He said that distributed power supply strategies can better manage and control hospital power. In the data age, real-time supervision of hospital power consumption based on data interaction is more helpful to ensure the safety and stability of hospital electricity.
JCI standard: electricity safety is an important part of hospital safety
"From the complexity of the building, the hospital is the most complicated, with the highest level of safety, second only to nuclear engineering." Fang Qiang, deputy director of the Logistics Management Research Institute of Fudan Hospital, told reporters that the safety of buildings is mainly reflected in three aspects, namely : Electricity safety, environmental safety, and information security.
Hospitals are very dangerous. They need to ensure safety from the physical, spatial and biological dimensions. This is the most basic guarantee for hospital environmental safety. At the same time, the hospital is the most complex public building, with a large number of medical-specific power facilities and other building-wide power facilities. “The larger the hospital, the higher the complexity.†Fang Qiang said that the North Campus of Huashan Hospital affiliated to Fudan University, as an explorer of hospital smart buildings, actively explored the construction and development of green smart hospitals, and introduced them from smart logistics management. Schneider Electric's integrated power and weak integrated solutions and digital services help hospitals save about 18% of energy and improve the efficiency of manual operation and maintenance by about 20%, which ultimately improves the hospital's logistics power operation and maintenance capabilities and provides stable and reliable power for hospital operation and maintenance. support.
As the key project of the “5+3+1†project of the Shanghai Municipal Government, the North Campus of Huashan Hospital affiliated to Fudan University opened in 2012 with a beautiful environment and perfect medical facilities. It is a three-level medical, teaching and research institute. A general hospital is also one of the pilot reforms for public hospitals in the new tertiary hospitals in the suburbs of Shanghai. The management of Huashan North Hospital strictly follows JCI international standards and implements the same medical homogenization service as Huashan Maternal Hospital. The quality of medical care has been widely recognized by patients.
In the evaluation system of JCI, the safety of hospital electricity has been fully considered. This concept has a reference for the pursuit of quality and safety in hospitals at all levels across the country. Fang Qiang said that the greater the complexity of the hospital, the more complicated the problem of electricity safety. At present, domestic logistics management is subdivided into electricity consumption standards, security standards, and hospitality control standards, but integrated integration standards are still lacking in the field of logistics management.
Power outage risk warning: surgery is interrupted, CT is damaged, information system is shut down!
As the digitalization of hospitals deepens, more and more businesses in the hospital rely on IT, equipment and various facilities to operate. Once there is a problem with the power supply, the impact is very large.
The hospital relies on the power supply system from the front-end registration, charging, digital operating room, to the back-end hospital information system and data center computer room. In the event of a power outage, all hospital departments will be affected. For example, in the event of a power interruption during surgery, transient pulses can pose a threat to patient health. Therefore, the operating room needs to use an uninterruptible power supply to ensure the stability of the power supply.
Many medical equipments in domestic hospitals are imported. For example, imaging equipment such as CT and MRI are mostly imported equipment. The requirements for power supply stability are relatively high. Once the power failure occurs, the medical equipment is worn out. Therefore, the quality of the power supply directly affects the life of the equipment. With the help of front-end services and back-end technical power to improve the reliability of the power supply, the service life of the equipment can be further improved.
Based on the particularity of the power supply requirements in different scenarios of the hospital, Schneider Electric upgraded its power supply and distribution and energy efficiency management solutions for each department this year. Schneider Electric China's digital energy efficiency business market director Qu Yujuan said that Schneider Electric's Power Advisor power consultants, Energy Advisor cloud energy efficiency consultants and other digital consultant products and systems, can make the ward, operating room, video room, Multiple key application scenarios such as back office, power distribution room, data room, and terminal power distribution are safer and more efficient.
Focus on the present: two contradictions in the development of hospital electricity
The intelligent development of hospital logistics management is very rapid, but there are some contradictions when the ideal of wisdom is taken into reality. On the one hand, the momentum of rapid development, on the other hand, the traditional hospital system, the two sides meet these new challenges.
The highly integrated VS. service in charge of big data era trend is the height of each hospital system integration, logistics ground in front of the system should be open, integrated. The advancement of logistics and logistics can bring added value, so that the supply of hospital service system can keep up with the front-end business.
For example, logistics monitoring can predict the time when a patient enters the ward in advance, and can set the cooling time. While ensuring the patient experience, it greatly saves hospital energy consumption. Fang Qiang said that, however, in reality, it is implemented in the operation of the department. A general package of strong electricity and a general package of weak electricity is integrated in the process of infrastructure construction and is bound by traditional processes. It is difficult to achieve high integration. In addition, HIS does not open the interface, which makes it difficult for the device to communicate with other information systems, which further restricts the intelligent development of the logistics equipment.
Rapid development VS. Operation and maintenance shelved In recent years, hospital information technology has developed rapidly, and the information system of the logistics management department is also very advanced. Relying on these systems, the hospital logistics department can track the operating conditions, energy consumption, and voltage fluctuations of large hospital equipment. In contrast, the foreign logistics software interface is very old, it does not seem to be highly intelligent, but they are very full of operation and maintenance software. According to the analysis of the operation and maintenance log data, the operation status of the equipment can be accurately and timely analyzed and intervened in time. “We have visited Japanese automation products. Although the control system is very old, it is very good for daily use. Domestic hospitals are paying more attention to the construction and operation while paying more attention to the construction.†Fang Qiang said that although the hospital On the BA building automation system, the system is advanced and powerful, but many hospitals are not in use, and the logistics staff are very distressed. In a few years, the system is slowly out of date, and it has been difficult to develop without being idle.
Operation and maintenance data is an important starting point for hospital management decisions. For example, the General Manager needs data to convince the Dean to make long-term plans. "Like evidence-based medicine, management also needs to make decisions based on data and evidence." Fang Qiang said that a certain device can still be used for several years, and can not just read the instructions. Through the record analysis of the data, it can be judged whether the equipment function is aging, the past failures and repairs, etc., which is a reliable proof of equipment replacement.
Looking to the future: hospital energy supply security is more comprehensive
Many of the energy of foreign hospitals are provided by localization, and there are many green energy sources, which are not so common in China. Fang Qiang said that the self-supply capacity of hospitals in France and Germany is more than 50%, and the heat generated by power generation can be reused in the heating system. At present, Sanlian Power has been promoted in some hospitals.
No one can guarantee that the city's power supply will not be interrupted. Once the city's power supply is interrupted, how can it be solved? Can the domestic hospitals pass the interruption test of the city's power supply? It depends on the hospital's self-generation system. Fang Qiang told reporters that the hospital's specifications have requirements for self-generation. Once the city's power supply is interrupted, there is a ten-second interval between the city's power supply and self-generation. UPS as a supplement can guarantee the operation of the hospital's core system.
“The switching efficiency of the three power supply systems is too low, and the modern smart hospital solution can realize the automatic switching of the power supply system, thus ensuring the continuity of the hospital business.†Fang Qiang said that Schneider Electric has been deeply rooted in the medical industry for many years and continues to be committed to medical care. The industry provides a complete energy efficiency management solution that integrates strong and weak electricity, which can effectively help medical institutions overcome the current energy efficiency and power security.
