Description: Parable Post-Acute-Inpatient Software is a platform that consists of a web application (Parable Web App) and a mobile/tablet application (Parable Mobile App). Parable is used for wound documentation and collaborative wound management. The Parable Web App is a HyperText Markup Language (HTML) and JavaScript application loaded from the Parable Web Service and run within a web browser. The Parable Web App functions as an interface to view and analyze collected information including three-dimensional (3D) wound scans/images, measurements, and clinical assessments. It also provides aggregate analytical and reporting capabilities to segment and examine patient wound data.

The Parable Web Service functions as a managed service to provide a backend for Parable Mobile Apps (running on iPads) and Web Apps (running in browsers). The Parable Web Service runs in Amazon Web Services (AWS) GovCloud and is a collection of AWS services and Parable software. The service does not run on VA premises and is not connected to the production VA network. Parable stores basic patient demographics (not including the patient`s social security number or financial information) as well as clinical wound assessment information. Parable stores data collected using the Parable Mobile App and renders data to both the Parable Mobile App and Web App for analysis. It can transmit data to Veterans Health Information Systems and Technology Architecture (VistA) and VistA Imaging via the Parable Integration Appliance. The Parable Integration Application is the only component running on VA network. Data is encrypted both in transit and at rest.

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:

This entry covers the Desktop Edition of this technology and not any mobile versions. Please note that the implementation of mobile technology applications that operate on Mobile Operating Systems must be reviewed and approved by the Mobile Technology and Endpoint Security Engineering Team:
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.
