Anniversary Longnan Hospital is a comprehensive national third-class first-class hospital integrating medical treatment, teaching, scientific research, prevention and health care, and is the core hospital of Anniversary Oilfield General Hospital Group. For many years, hospitals have always attached great importance to informatization. According to the overall strategic layout of oilfield informatization construction, building a digital hospital is an important measure to realize the scientific management of the hospital. On the basis of fully drawing lessons from advanced management experience at home and abroad, the pace of digital hospital construction was accelerated by high-tech means, and a complete and advanced computer network system was established in medical units in the province, which greatly improved the quality, service and management level of hospitals and achieved initial results.
1, high starting point planning, high standard start, digital hospital construction has begun to take shape.
Building a digital hospital is an important embodiment of China's integration with the international community and improving the core competitiveness of hospitals after China's entry into WTO. Digital hospital is a hospital that uses advanced computer and network technology to effectively collect, store, transmit and integrate patients' diagnosis and treatment information, health economic information and hospital management information, and bring them into the medical care database of the whole society. The construction of digital hospital is based on hospital management information system (HIS), which consists of laboratory system (l is), medical image transmission and storage system (PACS), registration, collection, pharmacy, drug storehouse, material management, hospitalization management, electronic prescription, nurse workstation, dean's hospital inquiry, medical record statistics, logistics management, medical insurance management, electronic medical record, performance evaluation, office automation, local area network management, etc.
2. High-speed and efficient application system is good for hospitals and patients.
Informatization construction is based on the storage and transmission technology of medical information by computer and network, and realizes the overall automatic management of administration, finance, prevention, medical treatment, nursing, medication and logistics in the whole hospital. Its main characteristics are high speed, large capacity and high efficiency, which saves manpower for the hospital, saves time for patients and realizes a win-win situation for doctors and patients.
2. 1 PACS system-convenient storage, simple access and cost saving.
PACS system is a system applied in hospital imaging department. Its main task is to quickly store all kinds of medical images (including images generated by nuclear magnetic resonance, CT, ultrasound, various X-ray machines and other equipment) in a digital way through various interfaces, so that they can be accessed and used in time when clinicians need them, and at the same time, some auxiliary diagnosis management functions are added to facilitate clinicians to diagnose and treat critically ill patients.
The necessity and significance of PACS are mainly manifested in the following aspects:
2. 1. 1 No film management. When film is used as an image carrier to store a large amount of image data, there are at least the following defects: (1) With the increase of time, more and more films are stored in hospitals, and it takes a lot of manpower and material resources to save, manage and search. According to statistics, even well-managed hospitals have gone through many searches, loans and consultations. The loss rate will be around 10%; (2) The film stored for a long time will gradually deteriorate, reducing the image quality; (3) Although the unit price of each film is not high, Longnan Hospital spends more than 2 million yuan on X-rays every year, and the purchase and maintenance of film processors, film potions and other equipment are very expensive; (4) In the process of film use, the hospital needs a lot of space to store unused and finished films, develop films and fixative, and needs a lot of manpower and material resources for film storage, film development and regular maintenance to prevent film deterioration.
2. 1.2 medical research needs. Hospital imaging equipment produces a large number of examination images all the year round, so it is difficult for doctors to make full use of film as a carrier to store, communicate and present image information. How to compare a large number of images while retrieving them? How to help doctors define the image statistical characteristics of various diseases in order to extract the characteristics of diseases? How to do quantitative analysis or comparison of imaging? These are all needed for medical research.
2. 1.3 clinical diagnosis requirements. On the one hand, it is difficult to quickly find and deliver the image film when dealing with critical cases in urgent need of diagnosis and treatment, especially when inviting experts from other hospitals and different places for consultation. On the other hand, the current CT/MRI digital images generally have a gray level of 0-4095, but this is generated when shooting with the window width and window level adjusted, which will inevitably lead to the loss of image information, that is, 0-4095 is transformed into 0-255, and the window width and window level cannot be adjusted and cannot be distinguished. If you don't adjust the window width and window position, it is difficult to find some diseases.
2. 1.4 treatment demand. The emergence of a large number of treatment equipment and navigation equipment based on medical image positioning and guidance also urges the need to transmit image electronic data between imaging equipment and treatment equipment. Current treatment equipment, such as gamma knife, X knife based on accelerator, conformal radiotherapy, external irradiation treatment planning system, neurosurgery image navigation equipment, computer comprehensive diagnosis and treatment system, etc. , using one or more imaging equipment such as CT, MRI, DSA, PET and other accurate image data. As the basis of lesion location, three-dimensional reconstruction, tissue absorption coefficient correction, dose calculation and instrument guidance. Without unified network management and unified data format, there is a waste of redundant construction of scanners, magneto-optical disks and peer-to-peer networks.
2.2 LIS system-bar code is fast, safe and labor-saving.
LIS system is a subsystem of hospital information management system, which takes the process of patient testing samples as the main line, data processing as the center and quality control as the core management, and organizes all kinds of data information related to laboratory daily work. First of all, standardize the behavior of laboratory operators and the rationality and scientificity of data processing from the overall process, so as to reduce the work intensity and improve the work quality for laboratory operators; Secondly, the integration of LIS system and HIS system can realize the information sharing between them to the greatest extent and effectively eliminate information islands.
2.3 Performance appraisal system-reasonable analysis, saving and increasing efficiency
Hospitals pay attention to cost-effectiveness and achieve better medical service results with less investment. While meeting social needs and paying attention to social benefits, we can obtain corresponding economic benefits and improve the survival and development ability of hospitals. At the same time, as a hospital that people are satisfied with, Longnan Hospital also strives to control costs, insists on governing for the people, embodies people-oriented, and effectively alleviates the problems of "difficult to see a doctor" and "expensive to see a doctor".
2.4 rational drug use system-safe and reliable is a good helper for doctors.
The system is embedded in the hospital information management system in the form of controls. In the electronic prescription link, aiming at prescriptions that may cause drug harm to patients, such as overdose, contraindications and compatibility contraindications, a drug safety monitoring system is established to give early warning, prompt and display in real time to avoid drug injury accidents. If any doubt is found, the police will immediately alert the medical staff and record it in the safety log for future summary and analysis.
2.5 outpatient call system-effectively solve the "three long and one short" problem.
In the traditional medical process, people have to queue up to register for medicine, queue up to pay for medical treatment, and carefully identify doctors' prescriptions and medical records. Hospitals are often overcrowded and it won't take long to see a doctor. The process and efficiency of seeking medical treatment are more painful, and patients and their families are deeply disturbed.
Hospital informatization construction has solved this problem well. It is not only convenient for patients, but also liberates doctors to some extent. In the whole process of seeing a doctor, triage call not only makes the process of seeing a doctor clear, but also solves the problem of "three long and one short" of patients. One doctor and one patient not only facilitates patients but also liberates doctors. It not only improves the efficiency, but also enables patients to get the most efficient diagnosis and treatment services.
3. Looking forward to the future, information construction will escort the development of hospitals.
The informatization construction of Daqing Longnan Hospital lasted nearly 10 years, which provided favorable guarantee for the safety and sustainable development of the hospital. The informatization construction of Longnan Hospital has achieved overall planning, step-by-step implementation, rapid and stable. Especially on 20 10, Longnan Hospital adopted the world's most advanced wireless doctor's rounds office and patient safety wristband identification system, which provided a new idea for the life safety of oilfield workers and the safety of diagnosis and treatment in Longnan Hospital. Looking forward to the future, the sustainable development of information technology in Longnan Hospital should be in line with the international modern medical industry and play its due positive role in the rapid development of the hospital.
conclusion
The application of modern information technology is helpful to solve the problem of information asymmetry in the medical and health field, innovate the medical service model, better protect the life and health of oilfield workers and realize the goal of national health protection. At the same time, by going up one flight of stairs has created opportunities for the operation and development of Longnan Hospital.
