What it is – How it works

By ME-P Staff ReportersME-P Rack Servers

According to Dr. Richard Mata MS, a client-server system configuration occurs when one or more “repository” computers [ known as “servers”] store large amounts of data but perform limited processing. Communicating with the server(s) are client workstations that perform much of the data processing and often have graphical user interfaces (GUIs) for ease of use.

High Functionality

Both customizability and resource use is high, depending on the desired sophistication. Many clinical medical information systems that process data directly related to patient care use this configuration.

VA Example

For instance, the Veterans Health Administration, which has implemented what is likely the largest integrated healthcare information system in the United States, uses client-server architecture. Known as the Veterans Health Information Systems and Technology Architecture (VistA), this system provides technology infrastructure to about 1,300 care facilities, including hospitals and medical centers, outpatient facilities, and long-term care centers. VistA utilizes a client-server architecture that links together workstations and personal computers using software that is accessed via a graphical user interface.

Assessment

Overall, for hospitals that have the financial and manpower resources for a significant investment in IT, client-server architectures are the fastest-growing and typically the most preferred of the system architectures, due in large part to their local adaptability and flexibility to meet changing hospital and medical center needs.
