Geriatrics expert witnesses

Older patients present clinical profiles that differ in fundamental ways from the general adult population. The physiologic changes associated with aging — reduced renal clearance, altered drug distribution, diminished thermoregulatory capacity, sarcopenia, and compromised immune response — affect how disease presents, how treatment is tolerated, and how quickly a patient can decline when care falls short. Jurors and even treating clinicians outside geriatrics may not appreciate these distinctions without expert guidance.

A geriatrics expert bridges that gap. When a case turns on whether a nursing facility should have placed a resident on a falls prevention protocol, whether a prescribing physician exercised appropriate caution with an anticholinergic medication, or whether a hospital's delirium screening was adequate, the opinion needs to come from someone trained specifically in the medicine of aging. General internal medicine or nursing expertise alone rarely provides the clinical granularity that a contested elder care case demands. Retaining a geriatrics expert early — before expert disclosure deadlines — allows counsel to build a theory of the case on a clinically accurate foundation.

Nursing home neglect and abuse claims constitute the largest category of matters in which geriatrics experts are retained. These cases frequently involve pressure ulcers that progressed through preventable stages, unwitnessed falls resulting in hip fracture or head injury, dehydration and malnutrition, elopement incidents, and improper use of physical or pharmacologic restraints. The standard-of-care analysis in each of these scenarios draws directly on geriatric medicine principles.

Beyond long-term care, geriatrics experts appear in hospital-based cases involving inadequate delirium recognition and management, inappropriate discharge planning for cognitively impaired patients, and failure to conduct a comprehensive geriatric assessment before high-risk procedures. Misdiagnosis claims involving dementia — particularly the failure to distinguish reversible causes of cognitive impairment from irreversible ones — represent a growing share of the case mix. Polypharmacy-related adverse events, including falls attributed to inappropriate sedative or antihypertensive regimens, generate both plaintiff and defense engagements. Wrongful death cases involving older patients in any inpatient or residential care setting may also benefit from geriatric medicine testimony to contextualize the patient's baseline functional status and the clinical trajectory preceding death.

Profile verification begins with confirmation of medical licensure in the expert's primary practice state through the relevant state medical board database. Certification status in geriatric medicine — whether through the American Board of Internal Medicine or the American Board of Family Medicine — is confirmed against publicly available certification records. Profiles are also reviewed for publicly accessible disciplinary actions, board sanctions, malpractice judgments of record, and exclusions from Medicare or Medicaid participation.

Each expert is asked to provide a current curriculum vitae that documents clinical appointments, academic affiliations, teaching positions, publications, and prior expert witness engagements. Prior testimony history, including cases in which the expert has been deposed or testified at trial, is noted where disclosed. Experts who have not maintained active clinical practice within a period relevant to the case facts are identified so that retaining counsel can make an informed decision about potential vulnerability on cross-examination.

A geriatrics expert engagement typically begins with a records review phase. The expert reviews medical records, nursing notes, medication administration records, care plans, incident reports, and any relevant facility policies. For nursing home cases, survey and inspection records from the relevant state agency may also be part of the review. The initial review phase produces either a verbal summary of the expert's preliminary impressions or a written report, depending on the engagement structure and applicable discovery rules.

Report preparation follows for retained experts in jurisdictions requiring written disclosures. A well-prepared geriatrics report will identify the applicable standard of care by reference to clinical practice guidelines, specialty society position statements, or peer-reviewed literature; describe how the care at issue deviated from or met that standard; and address the causal link between any identified departure and the patient's documented outcome. Deposition preparation typically involves a focused review of the report, the opposing expert's disclosures if available, and anticipated cross-examination lines. Trial testimony in geriatrics cases often requires the expert to explain aging physiology and clinical decision-making in terms accessible to a lay jury without oversimplifying the clinical complexity that underlies the opinion.

Geriatric medicine is a recognized medical specialty with an established peer-reviewed literature, and opinions grounded in that literature generally satisfy the methodological requirements articulated under federal and analogous state evidentiary standards for expert testimony. The most durable geriatrics opinions connect each standard-of-care assertion to a specific, identifiable source — a clinical practice guideline from a recognized specialty organization, a peer-reviewed systematic review, or documented institutional policy — rather than relying exclusively on the expert's personal clinical experience.

Common Daubert vulnerabilities in geriatrics cases include opinions that conflate what a particular institution did with what the standard of care requires, testimony that assumes a single clinical pathway without acknowledging documented variation in practice, and causation opinions that do not adequately account for the patient's underlying disease burden. Counsel should probe these areas during expert vetting. An expert who can articulate the basis for each opinion in terms of published, reproducible methodology — and who has been tested on those opinions in prior depositions — presents a more defensible disclosure than one whose opinion rests primarily on experiential authority alone.
