An issue of fact exists as to whether plaintiff's decedent reasonably believed that the physician who treated him at defendant hospital was provided by defendant or was otherwise acting on its behalf. If so, defendant can be held vicariously liable for the physician's malpractice even if defendant did not have any "control in fact" over him (see Hill v. St. Clare's Hosp., 67 N.Y.2d 72, 79, 81). This issue of "apparent or ostensible agency" (id. at 79) is raised by plaintiff's evidence that her decedent's two visits to defendant's emergency room were at the direction of his HIP HMO's emergency line, not his HMO's primary care physician, and that neither she nor he ever sought treatment from a particular physician while he was at the hospital (see Shafran v. St. Vincent's Hosp. Med. Ctr., 264 A.D.2d 553, 558, citing Mduba v. Benedictine Hosp., 52 A.D.2d 450, 453; Noble v. Porter, 188 A.D.2d 1066, 1066-1067, also citing Mduba). Defendant's evidence that the treating physician was a HIP attending physician with privileges at its hospital does not suffice to show its entitlement to judgment as a matter of law. There is no evidence that plaintiff or her decedent were acquainted with the treating physician before the decedent's admission to defendant hospital, were ever advised of his purported affiliation with the decedent's primary care physician, or were told to notify him if problems persisted after the decedent's first discharge. The foregoing should not be understood as a finding that defendant exercised no control in fact over the treating physician (cf. Mduba, 52 A.D.2d at 452).
