I would say so, Signalbox. And their definition of Dignity is a collection of characteristics which does not replicate the wording in the EA (which may not be mandatory, I suppose), and omits both sex and gender reassignment - which suggests to me a conflation, especially given their policy on accommodating tg patients according to presentation and pronouns.
To treat someone with dignity is to treat them as being of worth, in a way that is respectful of them as valued individuals, being of equal value and worth irrespective of differences such as age, race, culture, gender, sexual orientation, social background, health or marital status, disability, religion or political conviction.
