The Court of Appeals addresses causation and substantial factor in making the link from negligence to harm:

ESTATE OF MABEL C. MOLONEY VS. BECKER
OPINION AFFIRMING
VANMETER (PRESIDING JUDGE)
NICKELL (CONCURS) AND TAYLOR (CONCURS)
2011-CA-001773-MR
TO BE PUBLISHED 4/19/2013
BRACKEN

VANMETER, JUDGE: The Estate of Mabel C. Moloney (“Estate”) appeals from the Bracken Circuit Court judgment, as well as its order denying the Estate’s motion for a judgment notwithstanding the verdict (JNOV), resulting in the dismissal of its complaint alleging negligence against John Becker. For the following reasons, we affirm. ***

Causation is a question of fact when “‘the jury may reasonably differ as to whether the conduct of the defendant has been a substantial factor in causing the harm to the plaintiff.’” Pathways, Inc. v. Hammons, 113 S.W.3d 85, 92 (Ky. 2003) (citation omitted). In a negligence case such as this one, “the jury resolves any conflicts in the testimony and also any conflicts in the reasonable inferences to be drawn from the testimony[.]” Horton v. Union Light, Heat & Power Co., 690 S.W.2d 382, 385 (Ky. 1985) (citations omitted).

Kentucky has adopted the “substantial factor” test to establish causation, which was explained in Deutsch v. Shein, 597 S.W.2d 141 (Ky. 1980), as follows:

“In order to be a legal cause of another’s harm, it is not enough that the harm would not have occurred had the actor not been negligent. (T)his is necessary, but it is not of itself sufficient. The negligence must also be a substantial factor in bringing about the plaintiff’s harm.

The word ‘substantial’ is used to denote the fact that the defendant’s conduct has such an effect in producing the harm as to lead reasonable men to regard it as a cause, using that word in the popular sense, in which there always lurks the idea of responsibility, rather than in the so-called ‘philosophic sense,’ which includes every one of the great number of events without which any happening would not have occurred. Each of these events is a cause in the so-called ‘philosophic sense,’ yet the effect of many of them is so insignificant that no ordinary mind would think of them as causes.”

Id. at 144 (quoting Restatement of Torts, Second sec. 431, Comment a.) In determining whether an event is a substantial factor in causing an injury, courts should consider:

(a) the number of other factors which contribute in producing the harm and the extent of the effect which they have in producing it;

(b) whether the actor’s conduct has created a force or series of forces which are in continuous and active operation up to the time of the harm, or has created a situation harmless unless acted upon by other forces for which the actor is not responsible;

(c) lapse of time.
Restatement (Second) of Torts § 433 (1965).
