"After care"

My husband had excellent care on ward 12 and 11. Ward 11 needed his bed. action taken. My husband was disconnected from his mobile unit. Then put in a family room and left for 2hrs. by this time not feeling very comfortable. He was then moved to ward 10 still disconnected.. he arrived at approx 5.30pm. I visited at 600pm no sign of any nurses. Time moved on and the needle in my husbands arm came out. He rang the buzzer for help. A trainee nurse came and said she was not allowed to do what was required. Shortly after another nurse came and dressed where the needle should of been put back in. time went on and the end of vising bell was rang just after 8. I wanted to speak to a nurse but yet a gain no sign of one. I drove home concerned re the care my husband was not getting. I text my husband had he been seen to. No he replied. Was now after 9 pm. I decided to ring the ward as i was concerned. The hospital telephone rang for 15 mins, before it was answered. The head nurse answered and i told her re the above, she replied ring back in 20 mins its staff change over. I said no my husband needs seeing now as his urine bag was filling too. I said i would be putting an official complaint in. I then was asked my husbands name then in .10 mins later i got a text from my husband he had been seen and was going to sleep. is this due to short staff or communication between each ward.
