What is Clinical Decision Support Software?

In practice, clinical decision support software is used to process patient data and generate outputs that clinicians can consider alongside their own judgment. It may flag drug interactions, suggest diagnoses, recommend care pathways, or prioritize cases, and compliance teams need to understand exactly how the tool influences clinical decisions, what data it uses, and whether clinicians can independently review and override its output.

The compliance significance depends on the jurisdiction and the software’s intended use. In the EU, CDS software may fall within the Medical Device Regulation or In Vitro Diagnostic Regulation if it has a medical purpose and meets the relevant device criteria, and AI-enabled versions may also raise obligations under the EU AI Act if they are classified as high-risk or otherwise in scope. In the US, the FDA’s approach to software as a medical device and clinical decision support functions is central, while privacy and security controls may also be required under HIPAA, ISO 27001, and ISO/IEC 42001 depending on the organization’s role and operating model.
