Does the doctrine of the Landlord's Responsibility doctrine apply in the context of medical malpractice?

Plaintiffs have provided no authority that this doctrine, which originated to hold landowners responsible for the negligence of contractors engaged to perform work on their property, has ever been applied in the context of medical malpractice, nor have they made any argument as to why the doctrine should be so applied. In the absence of such authority or argument, we need not address their contention. (People v. Ham (1970) 7 Cal.App.3d 768, 783, overruled on another ground in People v. Compton (1971) 6 Cal.3d 55, 60, fn. 3.)
