Interpreting a living will after stroke

Mr. Duffy is 83 years old and is admitted to rehabilitation 4 weeks after a right thalamic cerebral vascular accident (CVA). He has dysphagia, dysarthria, left hemiplegia, and is moderately-severely confused. He pulls out his nasogastric feeding tube and his physician decides not to reinsert it because of significant nasal tissue necrosis. The team recommends a gastrostomy tube for nutrition because of Mr. Duffy's lack of alertness and high risk for aspiration. Mr. Duffy has a Living Will that states he does not wish to have his life sustained with a feeding tube. He does not have a formal Durable Power of Attorney for Health Care. His wife has dementia and their daughters are making decisions for both parents. They are not sure about his wishes in this particular circumstance, but report that he said of a relative who died of cancer, "things went on too long because of that feeding tube." After 3 days, Mr. Duffy is more alert, and during a discussion about tube feedings he says, "I'll go for the works." His fluctuating alertness level prevents him from responding to this question again. His daughters feel he would not want the tube and suggest waiting to see if his swallowing improves in the next week before making a decision.
