Using Daubert to Defeat Causation in the Delayed Diagnosis Claim

The old maxim, "the earlier the treatment, the better the outcome" has been a longtime staple in plaintiffs' collection of so-called "expert medical opinions." Let's face it -- the notion that earlier treatment is preferable, while imprecise, seems like a logical conclusion for most of us. However, the Eleventh Circuit's recent decision in <i>McDowell v. Brown</i>, 392 F.3d 1283 (11th Cir. 2004), establishes that such general medical principles, which are typically based on no more than the expert physician's common-sense and anecdotal experience, are far too speculative to overcome an evidentiary challenge pursuant to <i>Daubert v. Merrell Dow Pharmeceuticals, Inc.</i>, 509 U.S. 579 (1993) and therefore fail to establish causation in a medical negligence case. This is particularly so in those cases where the defendant medical provider maintains that the plaintiff's unavoidable and unpredictable underlying condition -- and not an alleged delay in treatment -- caused the plaintiff's injury, such that the plaintiff would have experienced the same level of injury despite any alleged delay.
