SECOND APPELLATE DISTRICT

DIVISION SIX

KELLI WEIDEMIER, 2d Civ. No. B336569 (Super. Ct. No. 56-2018- Plaintiff and Appellant, 00513868-CU-MM-VTA) (Ventura County) v.

THOUSAND OAKS SURGERY CENTER, LLC, et al.,

Defendants and Respondents.

Kelli Weidemier brought a medical malpractice action against respondents Dr. Kapil Moza, Thousand Oaks Surgery Center, LLC (Surgery Center), and Virtuoso Medical Management, Inc. (Virtuoso). She appeals from the judgment entered in favor of respondents after a jury returned a special verdict finding that they had not negligently treated her. Appellant advances nine grounds for reversing the judgment. She contends: (1) the evidence is insufficient to support the finding that Dr. Moza was not negligent, and (2) the application of the doctrine of res ipsa loquitur should have resulted in a verdict in her favor. In addition, appellant claims the trial court erroneously: (3) admitted evidence of a $500,000 payment she had received in settlement of her action against a codefendant, (4) admitted hearsay evidence in support of the opinion of respondents’ expert, (5) restricted her cross- examination of the expert, (6) instructed the jury on the law of causation, (7) refused to instruct the jury on the law of agency, (8) quashed her subpoena duces tecum, and (9) denied her motion for a new trial and for judgment notwithstanding the verdict (JNOV). Appellant has moved for permission to file a second reply brief. We deny the motion and affirm. Factual Background In October 2017 appellant underwent posterior cervical spine surgery (surgery through the back of the neck) at Surgery Center. Dr. Moza was the surgeon. The anesthesiologist was Dr. Bradley Spiegel. Before beginning the surgery, Dr. Moza applied ChloraPrep, an antiseptic solution, to appellant’s skin at the surgical site. ChloraPrep contains chlorhexidine. Dr. Moza made two applications of ChloraPrep, each in the amount of 26 milliliters, “in order to super sterilize the area.” Dr. Moza testified: “I was trained in my residency and my fellowship to do two [applications] for infection prophylaxis.” “The reason we use chlorhexidine is because of its superior properties in terms of fighting infection or preventing infection compared to the alternative, which is Betadine . . . .” After applying the ChloraPrep, Dr. Moza watched it dry. But without Dr. Moza’s knowledge, chlorhexidine “trickled” into

2 appellant’s left eye, severely damaging it. Despite 10 eye surgeries, appellant claimed to be “almost a hundred percent blind” in the left eye. According to Dr. Moza, it was the responsibility of the anesthesiologist, Dr. Spiegel, to check appellant’s eyes during the surgery. Dr. Moza explained that he could not see her eyes because she was “face down in a frame” and was covered by a blue drape. Dr. Spiegel, on the other hand, “literally ha[d] access to the patient’s head, and face, eyes.” He was supposed to be “watching and monitoring the [patient’s] eyes continuously through the surgery.” Claim that Substantial Evidence Does Not Support No Negligence Finding as to Dr. Moza Appellant claims, “[T]he record as a whole does not demonstrate substantial evidence in support of the appealed judgment finding no negligence on Dr. Moza’s part, and the judgment should be reversed.” The claim is forfeited because in her “opening brief, [appellant] ignore[s] evidence supporting the judgment.” (Chicago Title Ins. Co. v. AMZ Ins. Services, Inc. (2010) 188 Cal.App.4th 401, 415.) Appellant sets forth only the evidence favorable to her. “An appellant asserting lack of substantial evidence must fairly state all the evidence, not just the evidence favorable to the appellant. [Citation.] . . . [¶] If the appellant fails to fairly state all material evidence, we may deem waived any challenge based on insufficiency of the evidence.” (Id., at pp. 415-416.) “An appellant cannot salvage a forfeited argument by belatedly addressing the argument in its reply brief.” (SCI California Funeral Services, Inc. v. Five Bridges Foundation (2012) 203 Cal.App.4th 549, 573, fn. 18.)

3 Even if the claim were not forfeited, we would conclude that substantial evidence supports the jury’s finding that Dr. Moza was not negligent. “In reviewing a claim of insufficiency of evidence, the appellate court must consider the whole record, view the evidence in the light most favorable to the judgment, presume every fact the trier of fact could reasonably deduce from the evidence, and defer to the trier of fact’s determination of the weight and credibility of the evidence.” (Rufo v. Simpson (2001) 86 Cal.App.4th 573, 614.) “‘[T]he power of the appellate court begins and ends with a determination as to whether there is any substantial evidence, contradicted or uncontradicted, which will support the conclusion reached by the jury.’” (Shade Foods, Inc. v. Innovative Products Sales & Marketing, Inc. (2000) 78 Cal.App.4th 847, 889.) “‘If this “substantial” evidence is present, no matter how slight it may appear in comparison with the contradictory evidence, the judgment must be upheld. . . .’” (People v. Overstock.Com., Inc. (2017) 12 Cal.App.5th 1064, 1079.) “[I]n ‘“any medical malpractice action, the plaintiff must establish: ‘(1) the duty of the professional to use such skill, prudence, and diligence as other members of his profession commonly possess and exercise; (2) a breach of that duty; (3) a proximate causal connection between the negligent conduct and the resulting injury; and (4) actual loss or damage resulting from the professional's negligence.’ . . .”’” (Powell v. Kleinman (2007) 151 Cal.App.4th 112, 122.) “Because the standard of care in a medical malpractice case is a matter ‘peculiarly within the knowledge of experts’ [citation], expert testimony is required to ‘prove or disprove that the defendant performed in accordance with the standard of care’ unless the negligence is obvious to a

4 layperson.” (Johnson v. Superior Court (2006) 143 Cal.App.4th 297, 305.) The testimony of Dr. Moza and his expert witness, Dr. Duncan McBride, constitutes substantial evidence that Dr. Moza complied with the applicable standard of care. Dr. Moza explained that, before he applied the ChloraPrep, he had isolated the surgical area by placing “boundary drapes” around the area: “the drapes have an adhesive boundary on them. So we sort of make a sequestered area, which is all you see is the incision, and then you have these drapes. [¶] The purpose and reason to use those drapes is just to prevent pooling, or inadvertent trickling, or traveling of these fluids anywhere outside the field. So those [drapes] were applied.” “[T]here are actually four separate drapes. You peel off the adhesive tape. . . . And then you put one side. Then you peel off another piece of paper, the second side, and then the third and the fourth, because you have a rectangle that has four sides.” “Once we know that the drapes are adhesed and they’re not moving around, then you proceed to the second step, which is chlorhexidine, which is the ChloraPrep.” Dr. Moza made two applications of ChloraPrep to the surgical site. The standard of care is to allow at least three minutes for each application to dry. Appellant acknowledges that “[t]he drying time of chlorhexidine is about three minutes.” Dr. Moza assumed the responsibility for assuring that the ChloraPrep had dried. He testified: “I applied the chlorhexidine. I watched it dry.
