In a medical malpractice lawsuit, expert testimony is often crucial for plaintiffs. Typically, the experts giving testimony are fellow medical professionals with substantial experience in the same field as the doctor being accused of negligence. Through their testimony, they attempt to show that the defendant failed to meet the standard of care which the patient was supposed to receive.
Establishing and meeting standards of care are obviously important in health care, which is why such standards are increasingly being tied to doctor pay. Government insurance programs like Medicare and Medicaid as well as provisions in the Affordable Care Act have set clear goals of paying doctors based on quality and value rather than just the number of services provided.
