IPU?

Hello all,
Sorry if this is a dumb question but what is an IPU?
My educated guess is that it is an 'In Patient Unit' but correct me if i am wrong.
I am looking to work in an LTC which also staffs and IPU, and I am wanting to know what kind of work is involved in that IPU?
Does it have a certain type of patient, ie geriatric /elederly/ortho-neuro etc or is it more along the lines of chronic care or LTAC facilities

thanks in advance for any feedback!
