This is a follow-up to Interoperability: Arrested Progress.
The FDA has recognized voluntary interoperability standards for medical devices: Improving Patient Care by Making Sure Devices Work Well Together.
The FDA and HHS has (my highlight):
published a list of recognized standards for interoperability intended to assist manufacturers who elect to declare conformity with consensus standards to meet certain requirements for medical devices.
The standards are searchable here: Recognized Consensus Standards. The Software/Informatics area currently lists 54 items.
Some consider this a “landmark announcement” (see here) but “voluntary” and “elect to declare” just seem like more of #1 (same old, same old) to me.
