never. seriously.
back in the day, I used to discourage people from going to the hospital, but as I look back on my career, when the patient wants to go, my boss wants them to go, my employer wants them to go, it's not worth trying to convince someone not to go. If they want an expensive taxi ride, I will give them one with a smile on my face.
COVID might have changed things a bit, but to me, it's not worth the personal liability. If the patient doesn't want to go, sign a refusal. if I think they really should go, call someone else to try to convince them that it's in their best interest, but at the end of the day, people have the right to make stupid decisions regarding their health care.
Now, if a patient doesn't want to go to the hospital, I will always recommend (and document) that they follow up with their personal doctor at the soonest available appointment.
