What Does a Nurse Expert Witness Do?

When legal cases involve questions about the standard of patient care, the role of the nurse expert witness becomes crucial.

Nurses are often the healthcare professionals closest to patients, managing their day-to-day care and monitoring their wellbeing. Because of this, they are uniquely placed to provide impartial insight into what went right, what went wrong, and whether accepted standards of nursing practice were met.

At Apex Experts, we work with a wide panel of nursing expert witnesses, their expertise is vital not only for claimants and defendants, but also for the court itself, which relies on their independent evidence to reach fair and balanced decisions.

What Is a Nurse Expert Witness?

A nurse expert witness is a registered nurse with significant clinical experience who provides independent, expert opinion in legal cases.

They may specialise in areas such as acute care, tissue viability, mental health, paediatrics, or community nursing.

Importantly, their duty is not to the party instructing them but to the court.

When asked “What does a nurse expert witness do?” the answer is multi-layered. They investigate records, assess whether nursing care met professional standards, explain technical issues in accessible terms, and provide written or oral testimony that can guide the outcome of a case.

Key Responsibilities of a Nursing Expert Witness

A nursing expert witness carries out a number of critical tasks, including:

1. Reviewing Clinical Records

Nursing documentation is central to most clinical negligence and personal injury cases. A nurse expert witness will examine patient notes, observation charts, care plans, medication records, and hospital policies to reconstruct what actually occurred.

2. Providing an Independent and Impartial Opinion

The credibility of an expert witness rests on their independence. A nursing expert witness does not act as an advocate for claimant or defendant. Their role is to offer a balanced, evidence-based view on whether the care provided was consistent with accepted nursing standards.

3. Explaining Nursing Standards and Practice

Nurses follow guidance set by the Nursing and Midwifery Council (NMC), national guidelines such as NICE, and local policies. An expert witness explains these frameworks to the court, showing whether the care delivered matched what a reasonably competent nurse would have done in the same situation.

4. Considering Breach and Causation

• Breach of duty: Was the nursing care below a reasonable standard?

• Causation: Did that shortfall cause or materially contribute to the patient’s harm?

These are often the central questions in clinical negligence cases, and the nurse expert witness provides the professional analysis needed to answer them.

5. Preparing CPR Part 35 Reports

The expert witness report is a formal document that sets out the expert’s opinion. It must comply with CPR Part 35, the Civil Procedure Rules governing expert evidence in England and Wales. This includes a declaration of independence and a statement of truth.

6. Giving Evidence in Court

Not all cases proceed to trial, but when they do, the nurse expert witness may be called to give oral evidence. They must be able to defend their opinion under cross-examination, demonstrating confidence, impartiality, and a thorough understanding of the issues.

Common Areas Where Nurse Expert Witnesses Are Instructed

Nurse expert witnesses are essential in a wide range of cases, including:

• Pressure ulcer and tissue viability claims

• Falls in hospitals or care homes

• Medication administration errors

• Infection control breaches

• Failure to monitor or escalate deteriorating patients

• Safeguarding, mental health, and psychiatric nursing

• Paediatric and neonatal nursing care

These are situations where nursing practice is at the heart of the alleged failing, and expert testimony is critical in determining liability.

Why Nurse Expert Witnesses Matter

For solicitors, a nursing expert witness can provide early screening reports that clarify whether a case has merit, saving time and resources. Their full reports can form the backbone of a legal strategy, setting out where standards were met or breached.

For the courts, nurse expert witnesses provide clarity. They translate complex nursing practice into clear, structured explanations that judges and juries can understand. Their independence ensures that the focus remains on facts and standards, not on advocacy.

For patients and families, the involvement of a nursing expert witness offers reassurance that their concerns are being taken seriously and investigated by someone with direct professional knowledge of the realities of care.

Final Thoughts

The role of the nurse expert witness goes far beyond simply giving evidence in court.

They act as investigators, analysts, educators, and interpreters - helping solicitors, judges, and clients understand whether care was reasonable, safe, and professional.
