"A total lack of communication on the unit"

Have not been able to fault the care my mum has received from the Royal Infirmary in Edinburgh over the past 5 years - until our last visit. She has had excellent care from all departments - Cardiology, Gastroenterology, A&E and many others. Mum had an out of hrs appointment for vomiting and severe abdominal pain. As a precaution the GP wanted mum to get a surgical consult to check nothing happening with her hernia or anything else.   We got checked into the unit in the evening with bloods taken. After that not one person spoke to us or came anywhere near us. I had to ask outside the ward for an update at over an hour later where I was told the blood work was back, they were waiting for doctor handover and for them to look at results. Again no-one came to check on mum at all. Mum chased again outside the ward and eventually a doctor came to see us, mum got x-rays and was released very late in the evening. We have no objections to having to wait for that long and totally appreciate how busy the doctors are (especially out of hours), however there was a total lack of communication on the unit about was happening and a lack of care to not even check on mum or offer her a drink of water (again appreciate she may have needed surgery and that fasting may be required - this information was only provided when we pushed about eating and drinking).
