This is obviously a situation which has to be resolved immediately, or your mum's recovery will be affected. You say about the district nurse - have they been asked? I know in my local area that the nurses would call in 4 times a day for this exact reason, because it is a short-term need. Have you asked the hospital for advice? A phone call to the ward consultant's secretary might be useful, they will have had this situation before and may have some advice or support to offer. No-one will want her recovery affected as, apart from the personal factor, this would be a complete waste of resources. Good luck.
