So, when I was having a "medically managed" miscarriage (of a much wanted baby), I was left to bleed out overnight until my haemoglobin dropped several points, then I had to go for an emergency ERCP in the morning.
The nurses were supposed to be measuring the blood lost, I had been really careful to make sure the blood was all collected as far as possible in the bed pans/containers they gave me, but I later found they poured the blood away without thinking to monitor it. I would say this was more down to poor practice rather than them being busy as it would have been such a quick but important thing to do.
The consultant the next morning was shocked that I had been left to bleed like that and that an ERCP hadn't been done overnight, given how much blood I was losing.
You could, I suppose, argue that if the staff were very busy, that might have had a bearing on my less than optimal treatment.
However, in the afternoon following the inappropriately delayed ERCP, I was too wobbly to walk and was not discharged by the doctors because I would not have been able to walk up and down steps to our house. One of the nurses thought it was her business to sneer at me for using the hospital "like a bed and breakfast". This was a middle-aged woman with some air of self-importance, so might have been a relatively senior one. Presumably, she wasn't too busy to be unkind to me, as it took extra time and energy to make an untoward comment?
Did I complain? No. I was bereaved of a much-wanted baby and had too much going on in my life. It didn't seem the best thing to do at that point,
Did I get good care? hell no. Not from the nurses, though the doctors were pretty kind.
(Not sure if these were nurses or had midwifery training, but all midwives start off as nurses.)
