Description: Carta Cartographer is a data platform that enables users to collect patient data in any source system to map the path of a patient’s stay in a hospital. This technology uses modern artificial intelligence (AI) techniques to read through the clinical notes and extract additional data to create a model of each patient’s journey throughout the hospital.

By default, this technology is hosted on VA’s premise but has the option of being hosted in the vendor’s cloud. The vendor’s cloud is also used to receive registry definition files, which serve as configuration information for the system.

This technology collects data from a facility’s existing Electronic Health Record (EHR) and stores said data within the platform’s infrastructure. This data is exposed to Docker Compose or Kubernetes. Data is sent to the vendor’s system via a query of the user’s database or via the user sending an extract file to the vendor. The data is then ingested into the vendor’s data pipelines and loaded into their neo4j database.

The TRM decisions in this entry only apply to technologies and versions owned, operated, managed, patched, and version-controlled by VA. This includes technologies deployed as software installations on VMs within VA-controlled cloud environments (e.g. VA Enterprise Cloud (VAEC)). Cloud services provided by the VAEC, which are listed in the VAEC Service Catalog, and those controlled and managed by an external Cloud Service Provider (i.e. SaaS) are not in the purview of the TRM. For more information on the use of cloud services and cloud-based products within VA, including VA private clouds, please see the Enterprise Cloud Solutions Office (ECSO) Portal at:
Technology/Standard Usage Requirements: Users must ensure their use of this technology/standard is consistent with VA policies and standards, including, but not limited to, VA Handbooks 6102 and 6500; VA Directives 6004, 6513, and 6517; and National Institute of Standards and Technology (NIST) standards, including Federal Information Processing Standards (FIPS). Users must ensure sensitive data is properly protected in compliance with all VA regulations. Prior to use of this technology, users should check with their supervisor, Information Security Officer (ISO), Facility Chief Information Officer (CIO), or local Office of Information and Technology (OI&T) representative to ensure that all actions are consistent with current VA policies and procedures prior to implementation.
Section 508 Information: This technology has not been assessed by the Section 508 Office. The Implementer of this technology has the responsibility to ensure the version deployed is 508-compliant. Section 508 compliance may be reviewed by the Section 508 Office and appropriate remedial action required if necessary. For additional information or assistance regarding Section 508, please contact the Section 508 Office at
