In a Louisiana medical malpractice action against a Louisiana physician, a person may qualify as an expert witness on the issue of whether the physician departed from accepted standards of medical care only if the person is a physician who meets all of the following criteria:
(a) He is practicing medicine at the time such testimony is given or was practicing medicine at the time the claim arose. “Practicing medicine” includes but is not limited to training residents or students at an accredited school of medicine or osteopathy or serving as a consulting physician to other physicians who provide direct patient care, upon the request of such other physicians.
(b) He has knowledge of accepted standards of medical care for the diagnosis, care, or treatment of the illness, injury, or condition involved in the claim.
(c) He is qualified on the basis of training or experience to offer an expert opinion regarding those accepted standards of care. In determining whether a witness is qualified on the basis of training or experience, the court shall consider whether, at the time the claim arose or at the time the testimony is given, the witness is board certified or has other substantial training or experience in an area of medical practice relevant to the claim and is actively practicing in that area.
(d) He is licensed to practice medicine by the Louisiana State Board of Medical Examiners under R.S. 37:1261 et seq., is licensed to practice medicine by any other jurisdiction in the United States, or is a graduate of a medical school accredited by the American Medical Association’s Liaison Committee on Medical Education or the American Osteopathic Association.
