Based on the nursing sisters and practitioners I have known...I think staff consciously and reflexively work on these sort of interactions. I think most women and men I have known who work as nurses (and some midwives) are capable of dealing with a havering husband.
The patient is the centre of care, that is the mantra, action is based on clinical need not because Nigel feels his wife needs extra pillows...
But I think that the extra bodies there during the night, when staffing is reduced anyway, could put alot if pressure of the 'can I get a drink of water' kind.
A lot of posters have stated they would like their partner there but not other peoples partners there - myself included. Am wondering why, from a feminist perspective, women are encouraged to reject that first impulse -I would like a person I love to be with me - and defer to the needs of others rather than looking at ways this could be achieved to suit everyone.
Some hospitals are already doing it but fur it to be universal it would require substantial
Investment in 'family rooms' etc and we all know how likely that is unless you are willing to pay fur it
