One of my worst experiences was working for some bank that used MUMPS and trying to recover the (accidentally) erased editor string before someone would notice that it was gone. (Yes, the editor is a string, and it behaves just like any other string and globals are auto persisted to disk so if you wipe the editor string then much good luck to you.)
Banks and healthcare share a number of elements one of which is large budgets and those peddling MUMPS and associated (expensive consultancy) services saw an opportunity and ran with it. The fact that it eats up your hardware probably didn't go unnoticed and I'm pretty sure that in that world 'kickback' isn't a dirty word.
Seriously, dont.
