Substantive Sub-Areas

IV. Substantive Sub-Areas

A. Surgical and Anesthesia Errors

Surgical and anesthesia errors are paradigmatic medical-malpractice claims and frequently the most evidentiarily challenging. Liability theories include wrong-site or wrong-patient surgery, retained foreign objects, anesthesia overdose or hypoxic injury, nerve injury from improper positioning, and failure to obtain informed consent. The doctrine of res ipsa loquitur, recognized in California medical-malpractice cases since Ybarra v. Spangard (1944) 25 Cal.2d 486, can shift the burden of producing evidence to multiple defendants where the plaintiff was unconscious during the negligent event and the injury is of the type that ordinarily does not occur absent negligence. Ybarra itself involved a shoulder injury sustained during an appendectomy while the patient was anesthetized; the Supreme Court permitted the inference of negligence to be drawn against all defendants who had control over the plaintiff's body, even though the plaintiff could not identify which defendant caused the injury.

California also requires hospitals to report serious "adverse events" — including surgical retention of foreign objects, wrong-site surgeries, and patient deaths from medication error — to the Department of Public Health under Cal. Health & Safety Code § 1279.1. These reports are an underutilized investigative tool for plaintiffs' counsel and can establish pattern evidence that supports both standard-of-care expert opinions and EADACPA reckless-neglect theories.

B. Misdiagnosis and Delayed Diagnosis

Misdiagnosis and delayed-diagnosis cases — particularly cancer, cardiac event, stroke, and infection cases — present distinctive causation challenges. The plaintiff must establish not only that the standard of care required earlier or different diagnosis but also that the delayed diagnosis caused a worse outcome.

California rejects the loss-of-chance doctrine. In Bromme v. Pavitt (1992) 5 Cal.App.4th 1487, the Court of Appeal squarely held that, in a wrongful-death action, the plaintiff must prove that earlier diagnosis would have, more likely than not, prevented the death. A showing that earlier diagnosis would have given the patient a "better chance" — for example, a 30% rather than 15% chance of survival — is insufficient as a matter of law. Bromme makes California one of the more restrictive jurisdictions on this issue; many other states recognize the loss-of-chance doctrine as an independent theory or as a damages-allocation rule.

Plaintiff's counsel must therefore obtain expert testimony establishing that earlier diagnosis would have produced a probability of better outcome exceeding 50%. Where the underlying disease has a poor prognosis even with timely diagnosis, Bromme may be fatal to the wrongful-death theory and may push counsel toward a survival action focused on conscious pain and suffering during the period of delay.

C. Birth Injuries and Obstetric Negligence

Obstetric negligence presents a constellation of distinctive doctrinal and evidentiary issues. Causation in hypoxic-ischemic encephalopathy (HIE) and cerebral-palsy cases requires sophisticated expert review of fetal heart-rate tracings, umbilical-cord blood gases, neonatal MRI imaging, and Apgar scores. The standard of care in shoulder-dystocia cases turns on the application of standardized maneuvers (HELPERR, McRoberts) and the documentation of the timeline.

The minor-injury limitations rules in § 340.5 are particularly consequential here. A child injured at birth has, at most, until the eighth birthday to bring suit (where the injury occurred before the sixth birthday), and the limitations period is not tolled by minority. Counsel handling birth-injury claims should therefore commence record review and expert evaluation immediately upon retention, regardless of the child's age, because expert availability and record completeness deteriorate over time.

D. Hospital and Nursing-Home Negligence (and the EADACPA Distinction)

California's Elder Abuse and Dependent Adult Civil Protection Act (EADACPA), Cal. Welf. & Inst. Code § 15600 et seq., provides an independent and substantially more powerful cause of action against custodial healthcare facilities — typically nursing homes, residential care facilities, and skilled-nursing units — that engage in neglect, abuse, or fiduciary abuse of elders (65 and older) or dependent adults. EADACPA is not merely a relabeled negligence claim: it is a separate statutory scheme, the application of which has been the subject of a substantial body of California Supreme Court authority.

In Delaney v. Baker (1999) 20 Cal.4th 23, the Supreme Court held that EADACPA's enhanced remedies, codified in Cal. Welf. & Inst. Code § 15657, are available where the plaintiff establishes by clear and convincing evidence that the defendant engaged in recklessness, oppression, fraud, or malice in the commission of neglect. Delaney held that "neglect" under EADACPA refers to the failure of those responsible for attending to the basic needs and comforts of an elderly or dependent adult, not the negligent provision of medical services as such. The statute thus targets the custodial relationship rather than the professional-medical relationship.

In Covenant Care, Inc. v. Superior Court (2004) 32 Cal.4th 771, the Supreme Court reinforced the Delaney line, holding that the heightened pleading requirements of Cal. Code Civ. Proc. § 425.13 — which requires court permission to plead punitive damages against a healthcare provider — do not apply to EADACPA claims because such claims sound in elder-abuse rather than in professional negligence.

The practical significance is enormous. A successful EADACPA claim entitles the plaintiff to:

• Reasonable attorney's fees and costs under § 15657(a) — a fee-shifting provision that fundamentally changes the economics of nursing-home litigation;
• Pre-death pain and suffering under § 15657(b) — overriding the general California rule that survival actions cannot recover the decedent's pre-death non-economic losses;
• No MICRA cap — because EADACPA recklessness damages are not "professional negligence" damages within the meaning of § 3333.2.

The doctrinal line is not always crisp. A nursing-home pressure-ulcer case may sound in EADACPA where the gravamen is the systematic failure to reposition, hydrate, and feed a vulnerable resident; the same case framed as a deviation from a written wound-care protocol may sound in professional negligence. Delaney and its progeny require heightened pleading specificity: the plaintiff must allege facts establishing recklessness, not merely negligence, and must identify the conduct of identifiable defendants — typically through a combination of medical records, staffing logs, and citation history from the Department of Public Health.

The doctrine of res ipsa loquitur recognized in Ybarra v. Spangard (1944) 25 Cal.2d 486 retains particular force in nursing-home cases involving unwitnessed falls, pressure ulcers, and medication errors, because the resident is often unable to testify and the facility controls the only contemporaneous documentation. Landeros v. Flood (1976) 17 Cal.3d 399, while arising in the pediatric battered-child context, established a parallel principle that healthcare providers can be liable for failure to recognize and respond to a recognizable pattern of injury — a principle increasingly applied in elder-abuse cases involving recurrent falls or unexplained bruising.

V. Standard of Care and Causation

A. Flowers v. Torrance and Expert Testimony Requirements

The standard of care applicable to a healthcare provider in California is "that level of skill, knowledge, and care in diagnosis and treatment ordinarily possessed and exercised by other reasonably careful and prudent physicians in the same or similar locality and under similar circumstances." In Flowers v. Torrance Memorial Hospital Medical Center (1994) 8 Cal.4th 992, the California Supreme Court clarified that the standard of care in a medical-malpractice action is a single, unitary standard — there is no separate, lower "ordinary care" standard for ministerial or non-clinical acts performed by healthcare professionals. The standard of care is what a reasonably prudent professional would do under like circumstances, and that standard must, except in narrow circumstances, be established through expert testimony.

The narrow exceptions are situations where the alleged negligence is so obvious that a layperson can recognize it without specialized training — the surgical-sponge case, the wrong-leg amputation, the patient who falls from an untended gurney. Outside those narrow circumstances, the absence of qualified expert testimony will defeat the plaintiff's case at summary judgment. Counsel must therefore retain qualified standard-of-care and causation experts at the earliest possible stage and must scrutinize defense expert qualifications under Cal. Evid. Code § 720 and the Sargon line of cases.

B. The Substantial-Factor Causation Test

California applies the "substantial factor" causation test in negligence cases, including medical malpractice. Causation is established where the defendant's conduct was a substantial factor in bringing about the plaintiff's harm. The substantial-factor test is broader than but-for causation in some respects (it accommodates concurrent causes) and narrower in others (a trivial or theoretical contribution is insufficient).

In medical-malpractice cases, the causation inquiry is frequently the most contested element. As discussed above, Bromme v. Pavitt (1992) 5 Cal.App.4th 1487 forecloses the loss-of-chance theory in wrongful-death cases: the plaintiff must show that the negligent act, more likely than not, caused the death. In non-fatal cases, the substantial-factor test permits recovery where the negligence materially worsened the patient's condition, even if some injury would have occurred regardless. Causation must, like standard of care, be established through expert testimony in nearly all cases.

C. Informed Consent Under Cobbs v. Grant

The doctrine of informed consent in California rests on the foundational decision in Cobbs v. Grant (1972) 8 Cal.3d 229. Cobbs established that a physician has a duty to disclose to the patient all information material to a reasonable person's decision whether to undergo the proposed treatment, including the nature of the procedure, the material risks of the procedure, and the available alternatives.

Cobbs adopted a patient-centered (objective) standard for materiality: the question is what a reasonable patient in the plaintiff's position would have considered material, not what other physicians customarily disclose. This stands in contrast to the physician-centered standard adopted in some jurisdictions. Cobbs also requires the plaintiff to establish a causal nexus between the non-disclosure and the injury — that is, that a reasonable patient, properly informed, would have declined the treatment.

Informed-consent claims are theoretically distinct from negligent-treatment claims, but in practice they are frequently pled together. Counsel should be aware that the informed-consent claim may survive even where the underlying treatment was performed within the standard of care, because the gravamen of the informed-consent claim is the lack of authorization, not the quality of the care.
