Definition of Hospital Information System (HIS)
Hospital Information System (HIS) has been recognized as an important branch of the emerging Medical Informatics (Medical Informatics) in the international academic community. (Medical Informatics) is an important branch. The United States in the field of the famous professor Morris Collen in 1988 wrote an article for the hospital information system under the following definition: the use of electronic computers and communications equipment for the hospital departments to provide patients with diagnostic information and administrative information collection, storage, processing, extraction and data exchange capabilities, and to meet the functional needs of all authorized users.
What is PACS
PACS (picture archiving and munication systems) is known as medical image archiving and communication systems. In recent years, with the progress of digital imaging technology, computer technology and network technology and the rapid development of a comprehensive solution to the acquisition of medical images, display, storage, transmission and management of the integrated system. PACS has been rapidly popularized in hospital imaging departments. Just as computers and the Internet are increasingly affecting our daily lives, PACS is also changing the way imaging departments operate, and a highly efficient, film-free imaging system is quietly emerging. In these changes, the main roles of PACS are: connecting different imaging devices (CT, MR, XRAY, ultrasound, nuclear medicine, etc.); storing and managing images; and recalling and post-processing images. Different PACS can vary greatly in organization and structure, but all must be able to perform these three types of functions. For PACS implementation, each department may have its own implementation approach and scope of implementation depending on its location and economic situation. Regardless of whether it is a large, medium or small PACS, its establishment is no more than by the acquisition of medical images, high-capacity data storage and database management, image display and processing, as well as for the transmission of the image of the network and other components to ensure that the PACS to become a fully open system of the important network standards and protocols DICOM3.0.
What is lis
LIS( laborary information system) is a laboratory automation, now, the inevitable requirements of formalized management, the requirements to be able to provide the functions are:
Test order entry (patient information, results data)
Quality control (indoor quality control, inter-room quality control)
test data tools (data merging, modification, Historical data query)
Authorization of different users
Specialized software for microbial drug sensitivity
What is ris
RIS (Radioiogy information system), i.e., Radiology Information Management System. RIS is a software system that optimizes the management of workflow of the radiology department of a hospital, a typical process includes registration, booking, consultation and management. RIS is a software system to optimize the workflow management of hospital radiology department, and a typical workflow includes registration and appointment, consultation, image generation, film production, reporting, auditing, film issuance, etc. The RIS system contains PACS system, which is in conjunction with the peripheral modules of medical classification and retrieval, radiological material management, imaging equipment management and departmental information report, realizing the quality control of the patient in the whole process and field tracking, error statistics, and providing a basis for the reversal of the evidence for the disputes between the patients and the doctors, which makes the management of the radiology department enter into a clear-cut and clear-cut system. Radiology department management into a clear digital management stage.
The RIS process consists of detachable process links. Each link, in addition to accomplishing specific tasks, handles unexpected scenarios, including error handling and quality control.
