How does My HealtheVet pull data out of the respective VistA systems?
The process is as follows: To create a My HealtheVet account, your identity must be validated at a VA Medical Facility with a picture ID. The VA registrar will access the VistA system. You will be asked to enter a username. A password will be generated and given to you. You now have access to the My HealtheVet system. Once you have logged on to the My HealtheVet system, you can request a copy of key portions of your VistA record to be sent to My HealtheVet. The request from My HealtheVet is received by the VistA system. The VistA system retrieves the data and sends it to the My HealtheVet system. The next time you sign into the My HealtheVet system, there is a notification that requested data has been received and is available. If you select to merge this new data, it is merged with the existing information in your eVAult.
