Background
Samuel Hernandez suffered a cervical spine injury from a fall on February 17, 2020. He underwent an anterior cervical discectomy and fusion (ACDF) procedure at C5-6 and C6-7 on March 6, 2020, at Berkeley Medical Center. Post-operatively, he developed paraplegia and weakness in his left arm. The treating surgeon ordered a STAT MRI, which revealed persistent spinal stenosis, and he performed a second ACDF procedure the same evening. Despite these interventions, Mr. Hernandez remained unable to move his lower extremities. BMC discharged him on March 13, 2020, to a rehabilitation facility while quadriplegic and dependent on others for daily activities.
Approximately eleven months later, Mr. Hernandez underwent a third spinal surgery—a decompressive cervical laminectomy performed at a different hospital—which resulted in minor improvements in neurological function. Mr. Hernandez and his wife alleged that BMC nursing staff, therapists, and other non-physician care staff breached the standard of care by failing to escalate his deteriorating post-operative condition through the hospital’s chain of command, seek a second opinion, and advocate for proper physician intervention before discharge.
The Court’s Holding
The Intermediate Court of Appeals reversed the circuit court’s grant of summary judgment and remanded the case for trial. The court held that petitioners’ expert testimony regarding causation is sufficient to create a genuine issue of material fact and proceed to a jury.
The court found that the experts’ opinions were properly grounded in factual predicates: Mr. Hernandez’s documented post-operative condition, BMC’s written chain of command policies, and the applicable standards of care. Spine surgeon Dr. Richard Ozuna and hospitalist Dr. Aaron Leo Gottesman each opined, to a reasonable degree of medical probability, that had BMC care staff escalated Mr. Hernandez’s condition through the chain of command, the hospital would have communicated with a physician who would have ordered an MRI and spinal decompression surgery, resulting in a greater than 25 percent chance of improved recovery. The court distinguished this case from precedent holding expert testimony speculative, finding that the experts did not assume missing facts but rather opined how institutional procedures and applicable standards of care would have functioned.
The court emphasized that under West Virginia law, causation testimony need only warrant a reasonable inference by the jury, not establish absolute certainty. Any alleged gaps or contingencies in the evidentiary record go to the weight of the experts’ testimony, not its sufficiency at summary judgment. The circuit court erred in usurping the jury’s fact-finding role by discounting the experts’ opinions regarding the expected chain reaction of escalation and institutional response.
Key Takeaways
- Expert causation testimony in medical malpractice cases need only express a reasonable probability, not certainty, and is admissible if it warrants a reasonable jury inference of causation.
- When expert testimony is grounded in a health care provider’s own written policies and procedures, it may establish that escalation through the chain of command would have triggered institutional responses without being speculative.
- At summary judgment, courts must view all facts and reasonable inferences in the light most favorable to the nonmoving party; gaps in the record relating to weight of evidence cannot justify dismissal when causation testimony meets the reasonable-probability standard.
- In loss-of-chance cases, plaintiffs must prove to a reasonable degree of medical probability that following the standard of care would have resulted in a greater than 25 percent chance of improved recovery; interconnected expert testimony on both breach and causation can satisfy this burden.
Why It Matters
This decision provides important guidance on the threshold for surviving summary judgment in complex medical malpractice cases involving multiple care providers and institutional policies. The court’s holding clarifies that expert opinions grounded in hospital policies and standards of care do not become speculative merely because they rest on an expected chain of institutional responses. This is particularly significant for cases involving nursing and non-physician staff whose roles include escalating clinical concerns through established procedures.
The ruling reinforces that the admissibility of causation expert testimony—and its sufficiency to survive summary judgment—depends on whether it is grounded in facts and rises to the level of reasonable probability, not on whether every link in a causal chain is independently verified. By distinguishing between the weight of evidence (for jury determination) and its sufficiency (for summary judgment purposes), the court preserves the jury’s traditional role in evaluating complex medical causation where institutional procedures and professional standards require a chain of expected responses.
