I did read the post on midwife labour wards.
I delivered in American hospitals in a private labour and delivery room each time. The rooms were 'homey'. You could have food brought to you and to your labour partner. You could watch tv or listen to music. Each room had a private shower and loo, both pristine. There were two birthing suites with pools and birthing balls - first come first served unfortunately.
I had an epidural the first time, none for the subsequent four deliveries.
Afterwards I had a private room 3/5 times and double room 2/5 times.
For me the private room afterwards made a huge difference.
In all cases it was the standard of nursing care that contributed hugely to my recovery. The post natal nurses were superb. Ante-natal/labour nurses were also superb, with one exception. During each labour I had the same nurse with me until the end of her shift on each occasion, and despite a lot of monitoring the personal touch was there.
I see posts here all the time on the horror of sharing spaces with other women's husbands or partners or extended family after childbirth, and I have to say this would be my own personal worst nightmare.
On the two occasions when I had a double room I found it a bit awkward despite the curtains around each bed. First time around, the woman's mother had a quick fag in the ensuite loo/shower, so nasty around two little newborns, and the second time I think I must have been the roommate from hell as the woman was recovering from a CS and my dear little baby cried a lot and really loudly.
I overheard my roommate the second time relating the story of her delivery to a friend - calling her OB to say she was in labour, doctor advising castor oil and walking, eventually realising she needed to go to the hospital pronto, her hair-raising midnight trip to the hospital in an early summer thunderstorm, her husband parking in the multi storey car park, the pair of them making their way to the pedestrian bridge from the carpark to the hospital, she unable to walk any more, he having to leave her alone and run to find an emergency phone (it was 1998) and summon a wheelchair, a desperate run to the maternity unit with a pair of porters, one to wheel the chair and one to push open doors, immediate admission, baby found to be breach and no option but CS, her own OB arriving a couple of hours later...
The hospital pediatrician who was on duty that morning was the professor of pediatrics (it was a university hospital). He was my family's pediatrician, hence his visit to see little DD, and was assigned to her baby too as she had been admitted when he was on duty. Along with him came two residents (doctors learning their specialty of pediatrics). They chatted (as best she could with all the pain relief) and she mentioned their wild night and that the baby was about three weeks early. He said 'On no, he is full term' and showed her and the residents the crease pattern on the soles of the baby's feet that can indicate gestational age. She was adamant about it, and he let it drop.
I noted several details about her story.
First, the hospital did valet parking at no charge for anyone being admitted in an emergency and also obstetrical admissions. You could drive up to the emergency entrance, hand over your keys, and they would park your car and then leave your keys in an office where they could be picked up and given the location. My OB's office (all male OBs) gave all patients this information at 32 weeks. Little details can make a difference.
Second, castor oil.
Third of course was the miscalculated due date and the fact that the baby was breach.
Her doctor was a woman who had got a lot of things wrong. They were very lucky everything turned out ok.
There are no community MWs or HVs in the US afaik. You could phone the maternity unit any time if there were any post natal concerns, or call your doctor's or MW's office. The one time I had to return was to have a thrombosed hemorrhoid lanced and it was done expertly and to my great relief in a (male) gen surgeon's office exam room with local anesthesia.
My thinking on male v female HCPs is that they have all surely seen bodies before, and that patients are six of one and half a dozen of the other. I would prefer a male HCP any day over somebody's husband a few feet from me visiting his partner and baby, with me having to walk past all sorts of hangers on to get to a loo.
I suspect the same effect you ascribe to the midwife labour unit could be accomplished by providing private rooms, with or without all female staff. I freely admit I have no figures to back this up with, just the horror stories from women here.
