Why Expert Witness Matter So Much in Medical Malpractice Cases


Medical malpractice lawsuits typically stem from medical treatment that was inadequate or leaves a patient with additional and unnecessary injuries. In either situation, the victim is often left with an understandable distrust of the medical establishment. However, the success or failure of almost every medical malpractice case hinges on evidence presented by medical experts. At its most basic, medical malpractice lawsuits are seeking to prove that a doctor acted outside the scope of standard and appropriate treatment, and other medical experts are realistically the only individuals with the ability to evaluate this issue. In fact, the use of experts is so important in lawsuits generally that specific rules govern who can testify as an expert and the extent of what they are permitted to say. The Florida Supreme Court recently rejected rules passed by the state legislature on the use of experts in civil lawsuits, including a provision that directly regulates which experts can be used in medical malpractice cases. Understanding the legal standard doctors are bound to uphold for all their patients, as well as the specific role of medical experts in malpractice cases, is important information for individuals considering whether to sue.

Standard of Care

While doctors take an oath to “do no harm,” being injured as a consequence of medical treatment is not enough on its own to establish legal liability. As mentioned above, plaintiffs are trying to prove that a doctor’s course of treatment was inappropriate for the situation, which legally means he/she did not comply with the “prevailing professional standard of care.” This standard is measured against what other physicians with similar experience and skill would consider acceptable and appropriate treatment in like circumstances. If the injury occurred from direct action taken by the doctor, such as surgery, as opposed to not providing any or enough treatment, the plaintiff must specifically show that the injury was unnecessary or not a reasonable foreseeable result of the medical intervention.

Role of Experts

Experts are needed from the very beginning stages of a medical malpractice claim. An injured party cannot even file a lawsuit without an affidavit from a medical expert stating the applicable standard of care was breached. This requirement was put in place to reduce the number of unsupported lawsuits, but it also negatively serves to make it more difficult and expensive to sue a health provider. Beyond this preliminary opinion, experts provide the crucial link for judges and juries on how the treatment the defendant offered was out of line with the treatment that should have been offered. Some of the issues an expert may testify on include:

  • the method generally used to perform a particular procedure;
  • whether another doctor would have ordered same tests in a similar situation;
  • whether the lack of a diagnosis was reasonable based on the patient’s symptoms;
  • if the time between diagnosis and beginning of treatment was reasonable; or
  • whether the use of a specific medication was appropriate for a patient based on medical history and symptoms presented.
