Rule of Law:
In a medical malpractice action, expert testimony must establish both a breach of the standard of care and causation beyond mere speculation or conjecture. Testimony suggesting that an alternative course of treatment might have led to a better outcome is insufficient to create a material fact issue if it does not definitively state that the defendant's conduct fell below the standard of care and was the proximate cause of the injury.
Facts:
- On April 16, 1995, Archie Moreno presented to the Columbia Medical Center-East emergency room with abdominal pain, nausea, and vomiting.
- Moreno had a history of kidney stones, and his symptoms were consistent with that condition.
- Dr. Ascención Mena, the emergency room physician, conducted a thorough examination and ordered an extensive workup.
- Dr. Mena admitted Moreno to the hospital under the care of Dr. Murray Vann, a urologist specializing in kidney stones.
- Dr. Vann examined Moreno and did not find any symptoms inconsistent with a kidney stone or clearly indicating appendicitis.
- On the afternoon of April 18, 1995, Moreno’s symptoms changed significantly, and Dr. Vann immediately consulted a general surgeon.
- The surgeon performed an exploratory laparotomy within an hour, discovering a ruptured appendix.
- Following the surgery, Moreno developed complications, including sepsis and a wound infection.
Procedural Posture:
- Archie Moreno filed suit against Columbia Medical Center-East, Dr. Ascención Mena, and Dr. Murray Vann for medical malpractice in a Texas state trial court.
- The case proceeded to a jury trial.
- After the plaintiff, Moreno, presented his case-in-chief, all defendants moved for a directed verdict.
- The trial court granted the motions for directed verdict and entered a judgment in favor of all defendants.
- Moreno, as Appellant, appealed the judgment to the Texas Court of Appeals, but only as it applied to the physician defendants, Dr. Mena and Dr. Vann, who are the Appellees.

Issue:
Does a plaintiff in a medical malpractice case present sufficient evidence of breach and causation to overcome a motion for a directed verdict by offering expert testimony that speculates a different diagnostic approach 'most likely' would have prevented post-operative complications, especially when the same expert concedes the defendants' actions were thorough and that reasonable medical minds could differ?
Opinions:
Majority - Barajas, C.J.
No. A directed verdict is proper because the plaintiff failed to present legally sufficient evidence on the essential elements of breach of the standard of care and causation. The plaintiff's expert, Dr. Simpson, acknowledged that the defendants’ examinations were thorough, that the patient’s symptoms were atypical for appendicitis, and that reasonable medical minds can differ on a diagnosis without it constituting negligence. This undermines the claim of breach. Furthermore, Dr. Simpson's testimony that earlier surgery 'most likely would not have' resulted in complications amounted to speculation and conjecture, which is insufficient to establish a causal link beyond a mere possibility. Proof of mere possibilities will not support the submission of a case to the jury.
Analysis:
This case reinforces the high evidentiary burden on plaintiffs in medical malpractice claims, particularly concerning the quality of expert testimony. The court's decision emphasizes that a difference in medical judgment is not, by itself, evidence of negligence. It solidifies the principle that an expert's testimony on causation must be based on reasonable medical probability, not speculation or hindsight analysis. This precedent makes it more difficult for plaintiffs to survive a directed verdict if their expert's opinion is equivocal or framed in terms of possibilities rather than certainties.
