Nice application of HME. The runtime is pretty long especially if there are faults (which is not talked about). Also it is a big assumption that each institution will have equal sized data. That is never the case in practice, so inevitably there will be a hot spot. The other hurdles they mentioned: * data prep and transfer * harmonization of the data model are still hurdles for many institutions. The second one in particular although standards like FHIR and OMOP are increasing traction. Other data modalities like imaging would be more difficult.
