There are several challenges in aggregating health records from multiple sources, including merging data, preserving proper attribution, and allowing corrections. unfortunately, standards for exchanging medical records data, such as CCR and CCD, tend to focus on representing particular clinical data as some subset of a patient’s complete record. This provides a snapshot of a patient record, but there is very little to describe how a sequence of changes to the record should be interpreted as a coherent whole.there is something available that gives us the data aggregation, conflict resolution, and audit trail that what we want: the Wave federation protocol.
