Medical Malpractice Expert Witness Guide for Attorneys
How medical malpractice expert witnesses support standard-of-care, breach, causation and damages analysis in litigation.
What a medical malpractice expert does
A medical malpractice expert may evaluate the applicable standard of care, whether the care departed from that standard, whether an alleged departure caused injury and how the injury affected the patient. Different elements often require different specialties.
Standard-of-care analysis
The expert should understand the clinical setting and the type of provider whose conduct is being evaluated. Emergency medicine, surgery, nursing, radiology, obstetrics, anesthesia and other fields have different workflows and professional expectations.
Causation analysis
Even when a departure is alleged, causation may require a separate medical analysis. The expert should distinguish between the underlying disease process, preexisting conditions, expected complications and injuries allegedly caused by the disputed care.
Records and chronology
Complete records matter. Useful materials may include hospital records, imaging, operative reports, medication records, nursing documentation, laboratory data, pathology, prior treatment records and a reliable chronology.
Selecting multiple experts
Complex cases may involve more than one medical discipline. A single case can require experts in surgery, radiology, nursing, infectious disease, rehabilitation, life care planning or other specialties depending on the claims and damages.
Prepare for admissibility and cross-examination
Counsel should understand the basis for each opinion, confirm the expert is working within an appropriate field of expertise and anticipate challenges based on qualifications, methodology, prior testimony or potential bias.
