Healthcare interoperability enabled data exchange across institutions. What it never solved is patient sovereignty. Systems can retrieve records, but patients cannot determine who accessed what, when consent is still valid, or whether their data is being used as authorized.
Every research enrollment, clinical trial participation, and longitudinal outcomes study hits the same wall. Patients consent once but have no ongoing control. Data flows without transparency. The result is healthcare that operates episodically when it should operate continuously -- with the patient at the center.
