I work for a division of a health tech company and I can say that we hear you and value this kind of feedback. There are folks I work with who have dedicated themselves (including myself) to seek solutions to problems like these, and as a former integrations engineer, some companies are better at interoperability than others, despite the efforts of the HITECH Act in the US. My frustration is time and getting the attention of those who greenlight projects to work on things like these. On one hand, I feel OSS could help solve these problems sooner, but on the other hand, healthcare has some very opinionated people and things could get messy.
