Yeh, the structure is very very very confusing. Largely because you have the Hospital's themselves, then the trusts, then NHS England, or I guess now just the DHSC? And then occasionally even more layers in-between like health boards.
NHSE isn't merged into DHSC yet. Nobody knows what that's going to look like, or when we're going to know. There's every chance the new health secretary will have different ideas.
