How to Lock Expert Testimony to Survive Cross-Examination
Defense cross-examination in nursing home cases targets three vulnerabilities:
1. Over-generalization — the expert states what should have been done in general terms, without connecting it to the specific documentation in this case. Defense exploits this by introducing alternative scenarios and hypotheticals.
Lock it: Prepare the expert to anchor every standard-of-care opinion to a specific document, date, and entry in the record. "The standard required X, and the nursing note from March 14 at 0214 shows Y" is far more defensible than "nurses should always do X."
2. Causation ambiguity — the expert states that the breach was a contributing factor without specifying the mechanism. Defense argues that the outcome would have occurred regardless.
Lock it: Work with the expert to establish a precise causation pathway — breach, mechanism, injury progression, timeline — that forecloses the "wouldn’t have mattered" argument.
3. Standard-of-care scope — defense challenges whether the expert’s standard applies to this specific care setting, patient population, or clinical context.
Lock it: Use the regulatory overlay to anchor the standard to federal requirements that apply to every CMS-certified facility — eliminating the "it depends on the setting" objection.
