Solution 1:

Avoid ambiguity and use the full name if possible.

@waiwai933: This is what I've always done, I just wondered if there was any clever punctuation you could use to avoid this kind of rephrasing. I'm guessing from your immediate reply that the answer is probably no, but I'll see if anyone else comes up with something interesting.

That's correct. There's no real way around it, unless you've referred to it already, in which case you could step around mentioning the name altogether:

Its new surgical ward has just opened.
