Dillon v. Evanston Hospital

Dillon’s fifth amended complaint alleged not only negligent insertion, but also negligent inspection and removal of the catheter, failure to discover that a fragment remained in her body, and failure to inform her of that fact. Dr. Sener and the hospital did not challenge the sufficiency of the evidence supporting those other theories.

Under Illinois law, a general verdict based on multiple grounds will stand if at least one ground is sufficient. Because the defendants did not request special interrogatories, the court could not determine whether the jury relied on negligent insertion or one of the other negligence theories. The defendants therefore could not obtain reversal based solely on the asserted untimeliness of the insertion allegation.

The verdict forms showed separate findings for Dillon against Dr. Sener on ordinary negligence and on res ipsa loquitur. The evidence supported the negligence verdict, and the Court had already declined to overturn that verdict.

As with the amendment issue, an independently sustainable ground of recovery made reversal unnecessary. The Court therefore did not decide whether the res ipsa loquitur instruction itself was erroneous.

Although the defendants’ briefing inadequately supported this challenge with legal authority, the Court addressed the merits. Dr. David Snydman, an infectious-disease specialist, testified that the animation would help explain endocarditis, a condition for which Dillon faced an increased risk because of the catheter fragment.

Dr. Snydman specifically explained the differences between the infection depicted and the type of infection Dillon might suffer. The defendants also had a full opportunity to cross-examine him. Those safeguards supported the trial court’s conclusion that the video would assist rather than confuse or mislead the jury.

An offer of proof was unnecessary because the court plainly understood that Dr. Raaf would testify that Dr. Sener met the applicable medical standard of care. Defense counsel expressly confirmed that this was the subject of the proposed testimony.

The defense had already presented Dr. Richard Vasquez, who gave the same standard-of-care opinion. The defendants did not explain how Dr. Raaf’s testimony would differ materially from Dr. Vasquez’s or show that the experts called by Dillon and the catheter manufacturer were cumulative. A trial judge may limit repetitive evidence, including repetitive expert testimony.

The Court rejected the traditional all-or-nothing approach under which a plaintiff recovers full damages only if a future consequence is more likely than not, but recovers nothing if the probability is lower. That approach can overcompensate plaintiffs whose predicted harm never occurs while denying compensation to plaintiffs who bear a real, though less-than-even, risk created by negligence.

Illinois follows a single-recovery rule: a plaintiff must seek past and future damages in one action and generally cannot return later for another recovery if the anticipated harm materializes. Fairness therefore favors compensating the present burden of an increased risk rather than forcing the injured person to absorb that loss without a later remedy.

The plaintiff bears the burden of proving, to a reasonable degree of certainty, that the defendant’s negligence caused an increased risk. The future injury itself need not be more likely than not, but the award must be discounted to account for its proven likelihood. The Court concluded that this approach fits traditional damages principles while reducing the arbitrariness of the former rule.

The instruction merely listed “the increased risk of future injuries” as an element of damages. It did not tell the jury that the increased risk must be established by evidence rather than speculation, nor did it explain that the amount awarded must correspond to the probability that the future harm will occur.

Although the defendants did not specifically object to the instruction’s wording or tender an alternative instruction, the Court excused that waiver. Because the decision newly and definitively recognized increased risk as a compensable damages element, a correct instruction was necessary both to achieve a just result and to establish uniform guidance for future cases.

The Court approved the substance, though not necessarily the exact wording, of an instruction requiring the jury to find that the defendant’s breach substantially caused a present injury resulting in an evidence-based increased risk of future harm. It must then compensate the plaintiff only to the extent of the demonstrated probability of that harm. The Court reversed the $500,000 increased-risk award and remanded solely for a new trial on that damages element.
