(3) A cause of action may not be asserted against an individual or entity other than the licensee, the licensee's management or consulting company, the licensee's managing employees, and any direct caregivers, whether employees or contractors, unless, after a motion for leave to amend hearing, the court or an arbitration panel determines that there is sufficient evidence in the record or proffered by the claimant to establish a reasonable showing that:
(a) The individual or entity owed a duty of reasonable care to the resident and that the individual or entity breached that duty; and
(b) The breach of that duty is a legal cause of loss, injury, death, or damage to the resident.
For purposes of this subsection, if, in a proposed amended pleading, it is asserted that such cause of action arose out of the conduct, transaction, or occurrence set forth or attempted to be set forth in the original pleading, the proposed amendment relates back to the original pleading.
