Yes, it is possible to create a clinical decision support system (CDSS). However, it is a time-consuming process that requires a significant investment of resources and time. A custom decision support software can meet exact needs of the healthcare provider and offer a competitive advantage. However, using an existing CDSS means lower costs and faster implementation.In the end, choosing between the two boils down to the specific needs of the healthcare provider. Custom CDSS makes sense for large healthcare systems with resources and custom workflow, as well as specialized medical centers that focus on specific areas of healthcare, such as genetic disorders or less common types of cancer.
