It's common practice in peer-reviewed cardiology publications. Some titles are clearly constructed around the acronym (I guess the cool kids call that a "backronym"). We even cite the abbreviated studies (like PIOPED) in our medical notes, though I'll admit I don't enjoy doing it.
I specifically avoid speaking "like a doctor" around my kids; it induces a cringe like no other when I see teenagers trying to speak like an experienced MD.
That said, this Gianna girl seems well-composed, poetry and all.
