Digging deeper (as the comment above alone isn't worthy of HN, IMO): "People believe what they want to believe because of small sample sizes. When there isn't a black & white answer people go back to their personal experience, which is limited. They will not be right in the way you want to be right if you're practicing medicine." The family members are certainly exhibiting this. Are any of us, in this discussion?
Additional question: "Who is the patient? Is it the anxious family members who are being treated, or the person with fluid in the lungs?" The person with fluid in the lungs is the patient and the doc needs to be spending time on that person (the one who will die if not treated correctly). The family members are important but not in need of medical care. They can be handed off to an AI in the short term.
From my own vantage point, I've observed that the context switching between "caring for patient" and "dealing with family" can put a substantial drag on cognitive function for physicians. They do need to suck it up and deal with it since family members are the primary way in which patients receive post-release care in the US due to the non-existent safety net, and family member presence can really improve outcomes, but I'm not surprised that ChatGPT helps in producing the sort of bland prose that is well-received by family members.
