I would remove the comma, assuming the nursing home actually toppled over. Odd nursing home,however, the patient was very lucky not to have been killed.

Now if it was the patient who toppled over and broke his hip, then

the patient, who toppled over and broke his hip, resides in a nursing home.
Or:

"The patient, who resides in a nursing home, toppled over and broke his hip."
The patient resides in a nursing home, which toppled over giving the patient a broken hip.
Note: we both changed "which" to "who". Which refers to an object (as a building or a toaster), who refers to a person.
PsyDAG, the comma is not necessary between "home" and "which". Otherwise, if the nursing home toppled over, that's a better way to put it. :)
