Pathologists work in an environment in which, to the extent possible, diagnostic decisions are based on scientific principles. It can therefore be a rather shocking experience when a pathologist finds one of his or her diagnostic decisions being evaluated by a legal system developed and controlled by lawyers and judges rather than by scientists or pathologists. This experience can be even more troubling when a key participant in the proceedings is a fellow pathologist guiding a jury toward an unfamiliar interpretation of the pathology standard of care.
To provide the interested pathologist with the background information necessary to (1) understand the role of expert testimony in malpractice litigation and (2) understand why there can be a gap between expert opinions expressed in court and expert opinions expressed in a medical care context.
Medical literature review supplemented by review of subspecialty position papers, selected articles from newspapers and magazines, and legal decisions. The medical literature review was limited to articles published in English and was based largely on articles retrieved using the MeSH terms expert testimony/legislation & jurisprudence, and pathology/legislation & jurisprudence.
Medical error has become an increasingly important topic for pathologists, and although errors or allegations of error are evaluated in many ways, the evaluation with the most impact on the individual pathologist is a malpractice case. During the last decade physicians have increasingly become aware of the critical role played by expert testimony in malpractice litigation. Some physicians have asserted that providing expert testimony is the practice of medicine, and that it is unacceptable for juries to be presented with expert testimony that incorrectly describes medical practice standards. However, this opinion has been vigorously opposed by attorneys who feel that juries are best able to come to a correct conclusion if they base their deliberations on a broad spectrum of opinion. Gaining an increased role in the oversight of expert testimony would allow physicians to establish a closer alignment between opinions expressed in court testimony and opinions expressed in clinical practice. However, despite some physician success in inserting themselves into the oversight process, both physicians and physician organizations attempting to take action against misleading expert testimony continue to be vulnerable to legal attack.
