Dunnington v. Virginia Mason Med. Ctr. (Majority)Annotate this Case
This case involved a medical malpractice action for a lost chance of a better outcome. The parties jointly sought direct discretionary review under RAP 2.3(b)(4), challenging two pretrial rulings: (1) whether a court should use a "but for" or "substantial factor" standard of causation in loss of chance cases; and (2) whether evidence relating to a contributory negligence defense should be excluded based on the plaintiffs failure to follow his doctor's instructions. The trial court decided that the but for standard applies and the contributory negligence defense was not appropriate in this case. "Traditional tort causation principles guide a loss of chance case." Applying those established principles, under the circumstances here, the Supreme Court concluded a but for cause analysis was appropriate, and affirmed the trial court's ruling on that issue. The Court reverse the trial court's partial summary judgment dismissing the contributory negligence defense. The case was remanded for further proceedings.
