Your 90s experience jives with my 2000s experience. Thanks for sharing. I like your metaphor of annealing the data. Wish I'd thought of that. I naively assumed that because NHS issues GUIDs to patients (aka MRN, PID), their problem space would have been more tractable. For contrast, our systems in North America have the addition requirement of linking patient identifiers across heterogenous systems. Not easy. Alas, from the wiki article, it looks like NHS also fell victim to the parasites (aka consultants). https://en.wikipedia.org/wiki/NHS_Connecting_for_Health#Criticisms https://en.wikipedia.org/wiki/NHS_Connecting_for_Health#Crit... All the time since my own misadventures, I still have no clue how to mitigate the outsourcing grift.
