Does a nursing home resident in Ohio have the right to refuse a mechanical diet if he or she signs a form?

He is mentally competent. I understand that the Nursing Home does not want to be liable if he chokes and aspirates in his lungs. He has Cerebral Palsy and has dysphasia. He had heard that there is something called “Patients Right to Refuse” waiver that he could sign that would release the Nursing Home from liability. He said his only pleasure is food and says that purée the diet tastes bad. He is losing weight because he doesn’t eat very much. The Nursing Home staff lets him order outside food (which he pays for) and I send him food that he asks for. He hasn’t had a problem with outside food. He has been getting Vitalstim Therapy, which I believe is helping swallowing issues. I think I will urge him to request another swallow test reevaluation.
Thank you for your reply.

He has Cerebral Palsy. He has asked me to inquire for him. He had heard that a patient has a right to refuse this diet. He does have some swallowing issues due to dysphasia.
He says he wants to enjoy food and does not like the puréed diet. The Nursing Staff has said he can order outside of facility (and pay for himself) any type of food he would like. I have been sending him whatever food he asks for and bring him food when I visit. He has been tolerating the food he orders (and I send) without any issues. His wish is to sign a “Right to Refuse” waiver, if such a thing exists.

sounds like a good idea, especially if the previous one was done at a time when he was recovering from an acute illness or was very stressed out.
