In an action to recover damages for medical malpractice and lack of informed consent, etc., the defendants Huntington Hospital, Shahnaz Orner, and Marie J. Brignol appeal from so much of an order of the Supreme Court, Suffolk County (Emerson, J.), dated May 19, 2005, as denied those branches of their motion which were for summary judgment dismissing the complaint insofar as asserted against them.
Ordered that the order is reversed insofar as appealed from, on the law, with costs, and those branches of the motion which were for summary judgment dismissing the complaint insofar as asserted against the defendants Huntington Hospital, Shahnaz Orner, and Marie J. Brignol are granted.
“The requisite elements of proof in a medical malpractice action are a deviation or departure from accepted practice and evidence that such departure was a proximate cause of injury or
Here, in support of those branches of their motion which were for summary judgment, the defendants Huntington Hospital, Shahnaz Orner, and Marie J. Brignol (hereinafter the defendants) submitted an expert affidavit and deposition testimony which demonstrated that it was within acceptable standards of medical practice to continue gentamicin treatment even after the receipt of negative test results for sepsis, as the defendants reasonably continued to suspect sepsis and were concerned about the reliability of the tests, and that, even if it were not acceptable, the alleged departure did not cause the injury. The defendants thus satisfied their initial burden (see Williams v Sahay, supra; Reyz v Khelemsky, 10 AD3d 714, 714-715 [2004]; Estate of Mollo v Rothman, 284 AD2d 299 [2001]; Bellino v Spatz, 233 AD2d 355 [1996]). The conclusory expert affidavit submitted in opposition to the motion was insufficient to raise a triable issue of fact, as it did not address the assertions made by the defendants’ expert or otherwise explain why the continuation of gentamicin treatment was a departure (see Furey v Kraft, 27 AD3d 416, 418 [2006]; DiMitri v Monsouri, supra; Holbrook v United Hosp. Med. Ctr., 248 AD2d 358, 359 [1998]; cf. Taylor v Nyack Hosp., 18 AD3d 537, 538 [2005]) or state that such departure was a competent producing cause of the injury (see Jonassen v Staten Is. Univ. Hosp., 22 AD3d 805, 806 [2005]; Sheridan v Bieniewicz, 7 AD3d 508, 510 [2004]; Dellacona v Dorf, 5 AD3d 625 [2004]; Prete v Rafla-Demetrious, 224 AD2d 674, 676 [1996]; cf. Taylor v Nyack Hosp., supra).
In support of that branch of the motion which was for summary judgment dismissing the cause of action sounding in lack of informed consent, the defendants established their entitlement to judgment as a matter of law. In light of their failure to
