Medical Expert Witness Services
McCollum Consultants provides independent medical, surgical and nursing expert witnesses for a wide range of legal, regulatory and insurance matters. Our experts prepare independent medico-legal reports and provide specialist opinion within their field of clinical practice.
Expert Medical Evidence Across Complex Legal Matters
The specialist expertise required will depend on the medical issues and the nature of the case. We can assist in identifying an appropriately qualified expert, including where input is required from more than one clinical discipline.

Finding the Right Expert for Your Case
The appropriate expert will depend on the clinical issues requiring specialist opinion, rather than the type of proceedings alone. We can help identify an appropriately qualified medical, surgical or nursing expert. Where a case involves more than one clinical discipline, we can also assist in identifying the combination of expertise required.
Medico-Legal Reports and Expert Evidence
Experts can be instructed at different stages of a matter and for different forms of medico-legal opinion. Depending on the issues and the instructions provided, this may include:
Desktop reports
based on the medical records and other evidence, addressing issues such as breach of duty, causation or both.
Reports following consultation or examination
including opinions on condition and prognosis.
Supplementary and updated reports
where further evidence becomes available or additional questions arise.
Conferences
to discuss the medical evidence and issues within the expert's field.
Comment on pleadings and other case documents
where expert medical input is required before or during proceedings.
Peer review and second opinions
on existing expert reports or other medical evidence where an independent second opinion is required.
Joint expert meetings and statements
to identify areas of agreement and narrow the issues in dispute.
Oral expert evidence
at a hearing or trial where required.
Additional Medico-Legal Services
Screening Clinics
Our case screening clinics provide law firms and insurers with a fast, cost-effective way to assess the merits and viability of clinical negligence and personal injury claims. Experienced medical and surgical experts review the key evidence to identify important clinical issues and help inform early case strategy.
Scoping Calls
Preliminary scoping calls provide early access to specialist medical or surgical expertise before formal instruction. An expert can discuss the key clinical issues, clarify the scope of opinion required and help identify the most appropriate specialist expertise.
Medical Illustration Service
Our medical illustration service provides clear, accurate visuals to support medico-legal reports and expert evidence. Bespoke anatomical and surgical illustrations, medical imagery and clinical photography can help explain complex injuries, pathology, anatomy and treatment. As a result, complex medical evidence can be presented more clearly to solicitors, experts and the courts.
Medical Literature Service
Our medical literature service provides specialist searches to support expert witness reports and medico-legal cases. Relevant clinical research and peer-reviewed publications are identified, with clear references and summaries. This helps experts assess and reference the evidence relevant to their opinion.
Medical Statistics Service
Our medical statistics service provides specialist statistical analysis and actuarial life-expectancy calculations to support medico-legal reports and expert evidence. This analysis can assist medical expert witnesses and solicitors with life expectancy, future care requirements, damages and other complex quantitative issues.
