Kentucky Requires Explicit Specialty Standard-of-Care Proof and Limits Res Ipsa to Defendants with Control Over Retained-Object Causation

1. Introduction

This consolidated appeal arose from a total knee replacement surgery performed on Deborah Lloyd at Norton’s Women’s and Children’s Hospital. During closure, a suturing needle became dislodged from its holder and could not be located. The surgeon ordered an intra-operative x-ray; radiologist Dr. Darren Cain reported no unexpected radiopaque foreign body. A post-operative recovery-room x-ray was later read by radiologist Dr. Christopher Henley, who also did not identify a needle. Weeks later, imaging revealed a metallic foreign body consistent with a suture needle, and Lloyd underwent additional procedures and alleged complications.

After the surgeon (Dr. Sean Griffin) settled, Lloyd pursued claims against (i) surgical assistant Sheila Slone and (ii) the radiologists and their group, Diagnostic X-Ray Physicians, PSC. The central legal issues became:

• Expert-proof issue (radiologists): whether Lloyd’s orthopedic-surgeon expert could satisfy Kentucky’s requirement of expert testimony establishing the radiologists’ applicable standard of care, breach, and injury.
• Res ipsa issue (surgical assistant): whether res ipsa loquitur could substitute for expert testimony against a surgical assistant when evidence showed (a) the dislodgement could occur without negligence and (b) the surgeon controlled the decision to stop searching and close.

2. Summary of the Opinion

The Supreme Court of Kentucky reinstated summary judgment for both sets of defendants.

The Court of Appeals had reversed, reasoning (1) that cross-specialty expert testimony could go to weight rather than admissibility, and (2) that res ipsa applied because laypersons understand foreign objects should not be left in a patient. The Supreme Court characterized both as misframing the dispositive requirements: proof of the standard of care (radiologists) and exclusive control tied to the injury-causing event (assistant).

3. Analysis

3.1 Precedents Cited

A. Summary judgment framework

• Steelvest, Inc. v. Scansteel Serv. Ctr., Inc. — reiterates summary judgment’s function to terminate litigation where it would be “impossible” for the nonmovant to prevail, and emphasizes viewing the record favorably to the opponent.
• Paintsville Hosp. Co. v. Rose — cited within Steelvest for the “impossible to produce evidence” formulation.
• 3D Enters. Contracting Corp. v. Louisville & Jefferson Cnty. Metro. Sewer Dist. — confirms de novo appellate review of summary judgments.
• Pearson ex rel. Trent v. Nat'l Feeding Sys., Inc. — reiterates the appellate test: no material fact issue and movant entitled to judgment as a matter of law.
• Welch v. Am. Publ'g Co. of Ky. — underscores that the summary judgment inquiry is what is in the record, not what might later be developed.

These cases set the procedural lens: once expert deadlines have passed and the record lacks essential proof, CR 56’s purpose is to avoid a futile trial.

B. Expert testimony as an element in medical negligence

• Blankenship v. Collier — the Court’s anchor authority that in a “typical medical malpractice case” the plaintiff must present expert testimony establishing the applicable standard of care, breach, and resulting injury; also recognizes summary judgment is proper when the plaintiff fails to introduce evidence sufficient to establish the applicable standard.
• Perkins v. Hausladen — supplies the general rule requiring expert testimony, plus the two res ipsa-related exceptions in medical negligence (common-knowledge cases and expert-assisted res ipsa for complex matters).
• Neal v. Welker — quoted in Blankenship for the principle that litigation cannot proceed indefinitely on the hope “something will turn up.”
• Green v. Owensboro Medical Health System, Inc. — cited in Blankenship for the proposition that failure to identify experts and thereby prove standard of care warrants summary judgment.
• Mitchell v. Hadl and Blair v. Eblen — articulate that the duty is measured by the “reasonably competent practitioner” in the same class/specialty acting in similar circumstances.
• Baptist Healthcare Sys., Inc. v. Miller — emphasizes that where standards are not within lay jurors’ common experience, expert testimony on the applicable standard is properly required.

The Opinion uses this line of authority to separate two questions often conflated: (i) whether an expert can testify at all (qualification/admissibility), and (ii) whether the plaintiff’s proof contains the content the law requires (a stated standard of care).

C. Cross-specialty expert qualification versus sufficiency of standard-of-care proof

• Washington v. Goodman — used by the Court of Appeals to argue that qualifications go to weight once the expert is qualified.
• Owensboro Mercy Health Sys. v. Payne — quoted for the idea that physicians have been held qualified to opine outside their area; also for the notion that such differences may affect weight, not admissibility.
• Tapp v. Owensboro Med. Health Sys., Inc. — clarifies that a provider is not automatically disqualified from testifying against a different discipline.
• KRE 702 — invoked to acknowledge that experts outside the specialty can sometimes “assist the trier of fact.”

The Supreme Court did not reject these principles. Instead, it held they do not answer the dispositive question: even a qualified cross-specialty expert must still articulate the defendant-specialty’s standard of care. Here, Lloyd’s expert expressly disclaimed knowledge of the radiology standard of care, creating a fatal evidentiary gap under Blankenship.

D. Res ipsa loquitur in Kentucky and “exclusive control”

• Schechter v. Hann — provides the classic Kentucky articulation of res ipsa: the instrumentality is under the defendant’s exclusive control, and the injury is of a kind that ordinarily does not occur with proper care; presumption arises and the defendant must rebut.
• Jos. N. Rice Co. v. Grayson — cited for the inference that an accident would not occur absent a defendant’s wrongful act.
• Lewis v. Wolk (quoting Scott v. The London & St. Katherine Docks Co.) — reinforces that res ipsa depends on the defendant’s management/control and that the accident is one that ordinarily does not happen with proper care.
• Ashland Coca-Cola Bottling Co. v. Byrne — emphasizes res ipsa is grounded in the negligence of the person with “management or control” of the injury-causing agency.
• Saint Elizabeth Med. Ctr., Inc. v. Arnsperger — clarifies modern application, including that res ipsa allows an inference of negligence (not causation), and that expert evidence may be required when causative probabilities lie within expert knowledge.
• Savage v. Three Rivers Med. Ctr. — cited both for the proposition that res ipsa can permit inference of negligence from a retained item and, critically, that applying res ipsa to a particular defendant requires showing that defendant had “full control” of the instrumentality causing the injury; also underscores the need for expert testimony to identify standard of care and breach where required.
• Nazar v. Branham — recognized that retained-object cases can involve multiple actors and relationships in modern hospitals and that duties may be fact-specific; the majority used Nazar to highlight complexity rather than to expand res ipsa against every participant.

3.2 Legal Reasoning

A. Radiologists: qualification is not enough; the standard must be stated

The Opinion’s central move is to decouple admissibility/qualification from elemental sufficiency. The Court conceded that an orthopedic surgeon could, in principle, be qualified under KRE 702 to testify about certain radiology-related matters. But Kentucky malpractice law, as reiterated in Blankenship v. Collier, requires expert proof of:

• the applicable standard of care,
• breach of that standard, and
• resulting injury.

The Court treated “breach-sounding” language (e.g., a “stunning miss”) as inadequate because it leaves the jury to reconstruct a radiology standard through inference rather than testimony. The expert’s sworn admission—he did not know the radiology standard of care—meant the plaintiff could not prove a required element. That, in turn, made summary judgment appropriate under CR 56.

The Court’s rule is practical and formal: one cannot prove that a standard was “not met” unless the standard is first defined for the jury, and the standard must be the defendant’s specialty standard (Mitchell/Blair).

B. Surgical assistant: “exclusive control” must align with the injury-causing timeframe

The Court reframed the case from “a needle ended up retained” (a classic res ipsa motif) to a more granular causation story: the needle’s dislodgement itself did not injure Lloyd; the injury flowed from retention—the decision to stop searching and close despite uncertainty.

On this record, the Court found two facts dispositive:

• No negligence in loss: Plaintiff’s own expert conceded a needle can dislodge absent negligence and said of Slone, “She’s fine.”
• No control over retention: Kentucky’s statutory scheme (KRS 311.864(6) and KRS 311.864(4)) limits surgical assistants to aiding under direct supervision. The assistant could not order/read imaging, decide to reopen/continue exploration, or dictate the treatment plan—those decisions were attributed to the surgeon, i.e., the actor with constructive control once the needle was lost.

Thus, even if retained-object cases often trigger res ipsa, the Court held that doctrine cannot be used to pin negligence on an actor who neither (i) negligently caused the loss nor (ii) controlled the subsequent injury-producing retention decisions. The “exclusive control” element must match the period in which the alleged negligence produced the injury.

3.3 Impact

A. Litigation and expert strategy in Kentucky medical negligence cases

• Standard-of-care testimony must be explicit and specialty-tethered: Plaintiffs must ensure at least one expert will affirmatively articulate the standard of care for each defendant’s discipline (radiology, nursing, surgical assisting, etc.). It is no longer safe to assume that vivid criticism (“missed it,” “obvious,” “stunning”) will carry the “standard” element by implication.
• Qualification fights may be less important than content: Even when an expert survives KRE 702 qualification, summary judgment can still be granted if the testimony does not provide the legally required elements—especially the standard of care.

B. Res ipsa loquitur becomes more defendant-specific in retained-object cases

• Control is not merely “last hands on the object”: The Court emphasizes control relevant to the injury—here, “retention”—rather than the moment of loss.
• Team-based surgery does not automatically spread res ipsa: While cases like Nazar v. Branham recognize complex multi-actor settings, this Opinion signals that res ipsa cannot be used as a shortcut to keep every participant in the case absent evidence tying that defendant’s control and decision-making to the injury-causing event.

C. Settlement dynamics

Because the surgeon settled, the remaining defendants faced an effort to reallocate responsibility through res ipsa and generalized expert criticism. The Court’s approach limits that reallocation where the record shows the remaining defendants lacked the relevant control or the plaintiff lacks specialty-standard evidence. This may increase pressure on plaintiffs to secure comprehensive expert coverage early, before settlement or dismissal of central actors narrows the case.

4. Complex Concepts Simplified

• Standard of care: the professional benchmark—what a reasonably competent practitioner in the defendant’s specialty would do under similar circumstances (Mitchell v. Hadl; Blair v. Eblen).
• Expert testimony requirement: in most malpractice cases, jurors need expert help to understand the standard, whether it was breached, and whether that breach caused injury (Blankenship v. Collier).
• Res ipsa loquitur: a rule allowing a jury to infer negligence from the nature of the event when (among other things) the injury-causing instrumentality was under the defendant’s exclusive control and the event ordinarily doesn’t happen with proper care (Schechter v. Hann).
• Exclusive control / constructive control: “exclusive control” focuses on who had management authority over the thing or process that produced the injury; “constructive” control can exist even without physical possession when one has the authority to decide what happens next (here, the surgeon’s authority after the needle was lost).
• Summary judgment (CR 56.03): a pretrial ruling ending a case when there is no genuine dispute of material fact and the movant is entitled to judgment as a matter of law—often used when required expert proof is missing.

5. Conclusion

This Opinion tightens two recurring pressure points in Kentucky medical negligence litigation.

• First, it reinforces that expert testimony must do more than criticize outcomes: it must state the defendant-specialty standard of care. A qualified physician who admits he does not know that standard cannot fill the gap, and “breach-like” rhetoric cannot substitute for the missing element.
• Second, it clarifies that res ipsa in retained-foreign-object cases is not a universal net: the inference of negligence must be tethered to the defendant’s control over the injury-producing phase. Where the record shows the defendant neither negligently caused the loss nor controlled the retention decision, res ipsa will not eliminate the need for expert proof.

The broader significance is doctrinal discipline: Kentucky courts will continue to treat (i) standard of care, (ii) breach, and (iii) causation as distinct proof obligations, and will apply res ipsa as a targeted inference mechanism—not a substitute for element-by-element proof against defendants whose role and authority do not match the injury-causing conduct.
