Data Obscuration is Imposible
Data Obscuration is impossible. Fields and relationships are subtly linked. The people working on such projects lack experience and formal qualifications. And they don't understand hospital specialists, or even operation timing. Or if a surgeon dies or they are all at some conference, what guesses can me made. In all, people with high intervention rare diseases can be linked back, others less so. In Australia the university researchers were able to poke holes, because they were aware of some relationships . The most significant discovery was which hospitals are best, and which are the worst (infections, follow up corrections needed) which the insurance companies lapped up, but the researcher denied the ability to publish. When the ability to score surgeons against procedures , that too was banned from light of day. In all digital information is not welcome, when it identifies deficiencies.
