§ 2743.43.
(A) No person shall be deemed competent to give expert testimony on the liability issues
in a medical claim, as defined in section 2305.113 of the Revised Code , unless: (1) Such person is licensed to practice medicine and surgery, osteopathic medicine and
surgery, or podiatric medicine and surgery by the state medical board or by the licensing
authority of any state; (2) Such person devotes three-fourths of the person's professional time to the active
clinical practice of medicine or surgery, osteopathic medicine and surgery, or podiatric
medicine and surgery, or to its instruction in an accredited university; (3) The person practices in the same or a substantially similar specialty as the defendant. The court shall not permit an expert in one medical specialty to testify against
a health care provider in another medical specialty unless the expert shows both that
the standards of care and practice in the two specialties are similar and that the
expert has substantial familiarity between the specialties. (4) If the person is certified in a specialty, the person must be certified by a board
recognized by the American board of medical specialties or the American board of osteopathic
specialties in a specialty having acknowledged expertise and training directly related
to the particular health care matter at issue. (B) Nothing in division (A) of this section shall be construed to limit the power of
the trial court to adjudge the testimony of any expert witness incompetent on any
other ground. (C) Nothing in division (A) of this section shall be construed to limit the power of
the trial court to allow the testimony of any other witness, on a matter unrelated
to the liability issues in the medical claim, when that testimony is relevant to the
medical claim involved.
