Up to 50% of advanced imaging can be unnecessary for patients. xWave Technologies have developed xWave CDS, a clinical decision support system that aims to tackle the radiology backlog by supporting referrers and radiology teams to access the BEST TEST FIRST for their patients. xWave CDS can be deployed within xWave’s Smart Referring or Smart Vetting systems or can be seamlessly integrated into existing Order Comms/EPR/RIS/PACS via Hl7/FHIR interoperability.
