There is no verb.

Hi Maki,

Could we add something in the beginning like: (This is...) in order to make it acceptable?

Yes, we could:
"Ovo je udruženje specijalizovanih zdravstvenih ustanova za prevenciju invalidnosti i rehabilitaciju."

Thanks

You're welcome, dear.

That is correct. It is an institution.
