Facts
A patient suffering from peripheral vascular disease experienced severe pain and symptoms of impending gangrene in his right foot. Despite requesting a referral to a vascular surgeon, his primary care physician delayed the referral for 13 days. The vascular surgeon also delayed performing necessary diagnostic tests and treatments. Ultimately, the patient’s right leg was amputated below the knee. The plaintiffs alleged that the delays and negligence of both physicians reduced the chance of saving the leg (paras 2-5).
Procedural History
- Trial Court: Granted partial summary judgment in favor of the defendants, finding that the plaintiffs failed to establish causation to a reasonable degree of medical probability. However, the court allowed claims for pain and suffering to proceed and certified the issue of "loss of chance" for interlocutory appeal (paras 8-9).
- Court of Appeals: Certified the case to the Supreme Court of New Mexico, citing substantial public interest in the issues raised (para 8).
Parties' Submissions
- Plaintiffs-Appellants: Argued that the physicians’ negligence, including delays in referral and treatment, significantly reduced the chance of saving the patient’s leg. They relied on expert testimony to support their claim under the "loss of chance" theory (paras 5-7, 36).
- Defendants-Appellees: Contended that the plaintiffs failed to prove causation to a reasonable degree of medical probability, asserting that the evidence was speculative and insufficient to establish that earlier intervention would have saved the leg (paras 8, 36-37).
Legal Issues
- Should New Mexico recognize a cause of action for the "loss of chance" resulting from a physician’s negligence? (para 1)
- If recognized, do the facts of this case support a claim under the "loss of chance" theory? (para 1)
Disposition
- Majority: The Supreme Court of New Mexico recognized the "loss of chance" theory as a valid claim but held that the plaintiffs failed to prove causation to a reasonable degree of medical probability in this case (paras 40-41).
- Dissent: Justice Maes dissented, arguing that the plaintiffs presented sufficient evidence to raise a genuine issue of material fact regarding causation and that the case should proceed to trial (paras 42-49).
Reasons
Majority Opinion (Per Franchini CJ, with Baca and Serna JJ. concurring):
The Court recognized the "loss of chance" theory as a legitimate claim in New Mexico, aligning with the Court of Appeals' reasoning in a related case, Baer v. Regents of the Univ. of Cal.. The Court outlined the elements of the claim: duty, breach, loss or damage, and causation. It emphasized that causation must be proven to a reasonable degree of medical probability, not based on speculation (paras 9-30).
Applying the theory to the case, the Court found that the plaintiffs failed to establish causation. The expert testimony relied on incomplete medical records and speculative assumptions about the patient’s condition and the likelihood of success of earlier interventions. Without evidence showing that timely treatment would have likely saved the leg, the plaintiffs could not meet the required standard of proof (paras 34-39).
Dissenting Opinion (Maes J.):
Justice Maes agreed with the adoption of the "loss of chance" theory but dissented on the application to this case. She argued that the plaintiffs’ expert testimony raised a genuine issue of material fact regarding causation. The expert provided a reasonable basis for concluding that earlier intervention had a high probability of success, and the evidence should be evaluated by a jury. Justice Maes criticized the majority for improperly weighing the evidence on appeal and failing to view it in the light most favorable to the plaintiffs (paras 42-49).
