Wilkins v. Lamoille County Mental Health Services, Inc. and Copley Hospital, 2005 VT 121

Summary

The Supreme Court of Vermont affirmed summary judgment for Lamoille County Mental Health Services in a wrongful-death medical negligence action arising from a patient's suicide. The court held that the plaintiff's expert testimony did not establish that the alleged negligence was a but-for or proximate cause of the death, and declined to adopt a loss-of-chance theory. The court also held that expert testimony was required because the alleged negligence and causation involved complex psychiatric and medical issues.

Holdings

1. The plaintiff failed to establish but-for causation because the expert only testified that the decedent's suicide would have been less probable if the defendant had met the standard of care, not that it would not have occurred.
2. The substantial factor test is not a substitute for but-for causation; it is an alternate description of the cause-in-fact test except in cases of multiple sufficient causes.
3. Expert testimony is required to establish the standard of care and causation in suicide-related negligence claims because the causes, warning signs, and prevention of suicide are not within a lay juror's common knowledge.

Questions Presented

1. Whether the trial court erred in granting summary judgment because the plaintiff's expert testimony failed to establish but-for causation.
2. Whether the substantial factor test is a substitute for but-for causation in medical malpractice cases.
3. Whether expert testimony is required to establish causation in a suicide-related negligence claim.

Disposition
