Sigh. Colleagues and members of the community already gave good answers and pretty much explained why secondary use of openEHR data (and FHIR for that matter) is bound by constraints that also apply to every other information system. I wish I had better news.
I think there is a bigger issue here: managing expectations. This person is clearly frustrated because … water is wet. What I would like to know is why they think it would not be?
I would appreciate if someone could ask them the following:
What were your expectations from openEHR re secondary use? Do you have a reference approach or solution against which openEHR pales? Do you have an ideal solution that you could describe at any level of detail?
I am asking these questions with no intention of hostility. I would love to know what someone was expecting if they were so unhappy with a solution that, based on what I’m reading sounds more or less the state of the art: not only for openEHR, but for any data analytics solution fed from above-average-complexity data, let alone healthcare data, which is like Cthulhu compared to a Chihuahua in comparison to retail or finance.
The answers, if we could get them, would help those of us who design, implement and offer these solutions improve our communications. There may be a need for it.
