Miss. Code § 41-63-23
Accreditation and quality assurance materials, as defined in Sections 41-63-21 through 41-63-29, shall be held in confidence and shall not be subject to discovery or introduction into evidence in any civil action against the health-care professional or institution. No person involved in preparation, evaluation or review of accreditation or quality assurance materials shall be permitted or required to testify in any civil action as to any evidence or other matters produced or presented during the course of preparation, evaluation or review of such materials or as to any finding, recommendation, evaluation, opinion, or other action of such accreditation or quality assurance or other person involved therein. Information, documents or records otherwise available from original sources are not to be construed as being unavailable for discovery or for use in any civil action merely because they were presented or used in preparation of accreditation or quality assurance materials, nor should any person involved in preparation, evaluation or review of such materials be prohibited from testifying as to matters within his knowledge, but the witness testifying should not be asked about any opinions or data given by him in preparation, evaluation or review of accreditation or quality assurance materials.
