Fisherman : No. Not even 50 years ago. At most, private reproof.
The October 2022 Shepherd the Flock of God manual, Chapter 18 para. 3 (3) says:
If someone willingly accepts a blood transfusion, perhaps because of being under extreme pressure, a committee (not judicial) should obtain the facts and determine the individual's attitude. If he is repentant ... [otherwise] they should announce his disassociation.
As in all matters of "wrongdoing", repentence or the lack of it is key. This is a far cry from being thrown under a bus, but disassociation will follow if there is no repentance.
