Thanks for your question. As an old MUMPSter and InterSystems HealthShare trainer, I'll see what I can do to help.
Ensemble and HealthShare Training
InterSystems offers training on Ensemble and HealthShare, both online and in classroom settings. The online training is free. The costs for the classroom training can be found on our web site.
The primary staffing requirement from those who are implementing HealthShare is work on HL7 integration. To learn those skills, you need to understand Caché and Ensemble. The best online approach to those topics can be found in two learning paths: "Building Your First Application WIth Caché" and "Building Your First HL7 Production".
HealthShare online training is restricted to customers with HealthShare licenses, and others, at the discretion of InterSystems. Once you've got the HL7 production skills, I can help you inquire about access to those courses.
VistA is the VA healthcare system. It includes both enabling technology, known as the Kernel, and application modules. InterSystems does not train on VistA, but there are several organizations such as OSHERA and WorldVistA that do.
