Medical Expert Witness FAQs
What is a medical expert witness?
A medical expert witness is an appropriately qualified and experienced healthcare professional who provides independent, impartial evidence within their area of expertise to assist a court or tribunal.
Medical expert witnesses may include medical and surgical specialists, nurses, allied health professionals and rehabilitation specialists. Depending on their expertise and the case, they may provide opinions on matters including breach of duty, causation, condition and prognosis, treatment, care and rehabilitation needs.
What qualifications should a medical expert witness have?
A medical expert witness should have professional qualifications, knowledge, training and experience directly relevant to the issues on which they are instructed to give an opinion, together with an appropriate understanding of their duties as an expert witness.
For example, in civil proceedings in England and Wales, experts must comply with CPR Part 35, Practice Direction 35 and relevant Civil Justice Council Guidance for the Instruction of Experts in Civil Claims.
In addition, medical professionals must follow the professional and regulatory standards applicable to them, including relevant GMC guidance on providing witness statements or expert evidence.
Requirements may vary depending on the jurisdiction, court or tribunal in which the expert evidence is to be used.
What does a medical expert witness do?
A medical expert witness reviews the relevant evidence and provides an independent professional opinion on medical, surgical, nursing, healthcare or rehabilitation issues arising in a legal case.
For example, their work may include reviewing medical records, examining a claimant where appropriate, preparing a medico-legal expert report, answering questions, participating in discussions with other experts and giving evidence in court or before a tribunal.
An expert's opinion must remain within their area of expertise and be independent of the party instructing them.
