Yes & no. During the New Labour era there was far greater enthusiasm for EBM & as ever, the Treasury wanted pretty metrics that showed short-term "value for money", that's how so many people get unsuitably funnelled into 6-week "treatment packages" for complex longterm psych issues. The Tavi, as a psychoanalytic service, was under threat, just like the Royal Homeopathic Hospital, because neither looked good to either Treasury or EBM.
Gender had stacks of papers so to the untrained political eye, it satisfied "has evidence", it had defined, physical "treatments" & looked sciencey. For Tavi management it was an ideal fig leaf with which to protect the Tavi as a whole, both by generating income & by making the Tavi look more "medical" than purely psychoanalytic.
Lansley's 2012 Health & Social Care Act did balkanise the NHS, introduced insane levels of admin, & divorced the Secretary of State for Health from real responsibility for what happened in the NHS, which is a lot of the story of how things got so mad - it gave a whole slew of administrators more power, left them fighting for dwindling resources, & conveniently diffused responsibility.
Many of the same things seem to have played out in NI, particularly with respect to responsibility.
Edited for text I somehow managed to delete first time round.
