In the intensive care unit of the hospital where I work (the University Medical Center Utrecht), we rely on a Patient Data Management System (PDMS) called MetaVision. This system stands out for its exceptional configurability, making it an invaluable tool. With MetaVision, we have the ability to define and fine-tune various aspects, allowing for a truly customized system. The fundamental building block of this system is a parameter, which can be displayed and utilized across menus, graphs, tables, forms, and more. These parameters can store various data types, including text, numbers, dates, and more. Additionally, VB.NET scripts can be employed to further enhance and extend the functionality of these parameters.
