It's kind of a shame about VistA, the VA system. It's the most widely used well liked hospital system

>The VistA system is highly rated by physicians, receiving the highest overall score in Medscape surveys of over 15,000 physicians in 2014 and again in 2016, receiving particularly high marks for connectivity and utility as a clinical tool. https://en.wikipedia.org/wiki/VistA

and available free open source http://worldvista.org/AboutVistA/copy2_of_index_html

but hospitals instead spend hundreds of millions on Epic and Cerner who I presume have fancy sales teams to push those to hospital managers.

OpenMRS-based systems are widely used in the developing world in hospitals, not sure what the barriers are to first-world adoption.

It's also written in an obsolete, obscure programming language https://en.wikipedia.org/wiki/MUMPS .

Mumps is also used by Epic, the market leader and various banks. It or a variant is being developed by InterSystems who claim their system is the world’s fastest object database. So it struggles on. It actually sounds quite interesting tech.

I wouldn't call it obsolete (since it's still actively being used/developed in) or obscure (since there's a large and active user base). But it is a unique programming language.
