Ohio Rev. Code § 2317.54
No hospital, home health agency, ambulatory surgical facility, or provider of a hospice care program , pediatric respite care program, or pediatric transition care program shall be held liable for a physician's failure to obtain an informed consent from the physician's patient prior to a surgical or medical procedure or course of procedures, unless the physician is an employee of the hospital, home health agency, ambulatory surgical facility, or provider of a hospice care program , pediatric respite care program, or pediatric transition care program.
Written consent to a surgical or medical procedure or course of procedures shall, to the extent that it fulfills all the requirements in divisions (A), (B), and (C) of this section, be presumed to be valid and effective, in the absence of proof by a preponderance of the evidence that the person who sought such consent was not acting in good faith, or that the execution of the consent was induced by fraudulent misrepresentation of material facts, or that the person executing the consent was not able to communicate effectively in spoken and written English or any other language in which the consent is written. Except as herein provided, no evidence shall be admissible to impeach, modify, or limit the authorization for performance of the procedure or procedures set forth in such written consent.
Any use of a consent form that fulfills the requirements stated in divisions (A), (B), and (C) of this section has no effect on the common law rights and liabilities, including the right of a physician to obtain the oral or implied consent of a patient to a medical procedure, that may exist as between physicians and patients on July 28, 1975.
