edit: to clarify, by "this" I mean "stability". One path to build a medical software company has been to start by targeting individual practices, clinics, and small hospitals. That is still possible, and there are plenty of companies doing it. But that path is getting harder to take in the US because of medical industry consolidation. Even "independent" practices now usually have referring affiliations, and more often than not this means that they use the hospital network's existing software infrastructure.
