Medical Malpractice Cases: How Expert Testimony Can Strengthen Your Argument

Medical malpractice litigation is often won or lost based on expert testimony. For attorneys, having the right medical expert on your side can mean the difference between a dismissed case and a decisive verdict.

Why Medical Malpractice Testimony is Essential

Every medical malpractice case hinges on a key issue: whether the healthcare provider upheld the accepted standard of care in the circumstances. Because these standards involve intricate clinical knowledge, the average juror or judge cannot assess them unaided. Most jurisdictions even require expert testimony to move the case forward.

Expert witnesses, especially clinicians who specialize in medical malpractice, serve as interpreters of clinical complexity. They translate procedures, treatment protocols, diagnostic decisions, and medical outcomes into language that courts can understand. Without that bridge, the gap between legal strategy and medical reality becomes too wide to cross.

How Medical Expert Witnesses Define the Standard of Care

One of the most powerful roles an expert plays is establishing what the standard of care should have been in a particular situation. For example, in a case involving a surgical error, a board-certified surgeon can explain:

• What steps are considered medically appropriate
• How the defendant deviated from accepted norms

By articulating this clearly, the expert gives the jury a benchmark against which to evaluate the provider’s conduct. This is foundational to proving negligence—and to building a persuasive, fact-based case.

The Strategic Advantage of Board-Certified, Trial-Tested Experts

Not all experts are created equal. The impact of testimony from a seasoned, board-certified professional with litigation experience is often decisive. These individuals carry credibility that:

• Resonates with juries
• Withstands cross-examination
• Strengthens your overall case narrative

Their testimony brings clarity and credibility to your case argument, often helping facilitate earlier resolutions when opposing counsel recognizes the strength of your expert’s perspective.

Medical Expert Testimony That Delivered Results

In the 2022 case Reed v. Life Care Centers of America, expert nursing testimony helped drive a powerful verdict for the plaintiff. Johanna Ojeda, RN—an expert with over 30 years of clinical experience—testified that the nursing staff failed to meet the standard of care in treating a patient who developed a severe pressure ulcer.

In the interview provided by Johanna Ojeda, RN, her testimony:

• Cited federal and state regulations that mandate nursing home care standards
• Educated the jury on the staging and treatment of pressure ulcers
• Demonstrated how documentation and care plans were insufficient and poorly executed

She testified that the wound, initially recorded as a minor skin tear, progressed to an unstageable pressure injury—later determined to be Stage Four. Her detailed review of hospital records, nursing notes, and physician orders showed a clear failure to prevent and respond to skin breakdown.

The jury responded with a $12.35 million verdict, assigning 87% of the fault to the defendant. Ojeda’s expert testimony was pivotal in establishing liability and damages.

Best Practices Leveraging Expert Witness Testimony

Winning attorneys engage their expert witnesses early in the litigation process. This allows time for:

• Thorough review of medical records
• Alignment on legal and medical strategy
• Preparation of persuasive, written expert reports

Effective experts are also excellent communicators. They distill complex topics into understandable testimony that:

• Reinforces your argument
• Stays unbiased
• Remains professionally sound

Intentional Expertise Adds Value

What sets the most effective expert witnesses apart is their ability to remain focused, current, and highly relevant to the case at hand. Top-performing experts will:

• Limit their testimony to areas in which they have direct, recent clinical experience
• Hold current board certifications and unrestricted medical licenses
• Demonstrate familiarity with the legal concept of generally accepted standards of care

By intentionally aligning their testimony with their active field of practice, these professionals bring unmatched clarity and authority to court proceedings. Their focused expertise strengthens legal arguments, supports fair and equitable verdicts, and ultimately advances the interests of both the legal system and patient care.
