CareNexus® connects community-based providers and patients across the continuum of care. The solution gives organizations the patient data needed to enable providers the right information, for the right patient, at the right time -- improving care quality and data management. Connecting to any data source, including health information exchanges (HIEs), CareNexus® shares information with any Electronic Health Record (EHR) or care provider consolidating current systems into one HL7®FHIR® database. Extensible for future requirements through SMART-on-FHIR apps, CareNexus® is continually updated to support rapidly evolving standards. The HL7®FHIR® SMART App Launch Framework connects third-party applications to Electronic Health Record data, allowing apps to launch from inside or outside the user interface of an EHR system. With a secure, cloud-hosted HL7®FHIR® application infrastructure utilizing Microsoft Azure Kubernetes Services, CareNexus® adheres to FHIR Version 4 and United States Core Data for Interoperability (USCDI) standards and is HIPAA compliant. CareNexus® provides a reliable, secure authorization protocol for a variety of app architectures, including apps that run on an end-user’s device as well as apps that run on a secure server. Features include a modular and scalable design; standards and HIPPA compliance; consent, referral and program management; and appointment scheduling, task, and activity management.
