"Poor care, unacceptable attitudes"

My father was recently admitted to Walsall Manor with chronic stomach pains. He was admitted to ward 11 on Tuesday 15th October 2013, he was briefly diagnosed with gallstones and given pain relief. I visited on Tuesday evening and he was fine just in a lot of pain. I then returned on the Thursday afternoon as he was told he would need to stay in for approx. 1 week and he seemed really confused and very unwell. I asked the nurse what was the matter with him and she replied 'nothing' and seemed bemused by my questions. I explained that I was concerned my father seemed unrested, confused and had seemed to have lost weight. He had no water near him to drink and he had not eaten a meal in two days since being admitted yet his observation notes suggested otherwise.I bought him a prawn salad and some juice from the shop downstairs in the hospital and took it to him to eat, he could only manage half of it and said he felt 'strange' and unwell. He was very tired so I left him to rest and asked for the nurses to keep an eye on him. I knew there was something wrong but the nurses explained that they were unsure what the pain was but assured me that they were giving him plenty of pain relief to make him as comfortable as possible. The following day (Friday 18th) I returned to the hospital at approx 16.30pm, when I got to the ward my father was asleep, I woke him gently to find he was most confused. I thought it was just because he had been sleeping but he did not even know who I was, he was concerned I was taking him somewhere - I tried to explain who I was and what I was doing and he didn't understand, it took me a good hour to get him to realise I was his daughter - this was not only upsetting to me but extremely distressing for my father. After lots of investigating and talking to different members of staff, including demanding to see the doctor I discovered that the nurses had basically given my father an overdose of morphine based pain relief. They had not monitored his condition nor had they observed his well being at all. When I read through his notes it stated by 3 different people that my father was 'alert and communicating well' that he had been given a fat free diet of which he was 'eating and drinking well and taking good amounts daily' this was all complete lies as my father had not eaten for 3 days at all, only drinking very small sips of water and that on the Friday I got there he had been nil by mouth due to a test he had done in the morning which was due to end at 1pm that day and he could eat and drink - however, as they 'forgot' to delete this from his chart, it wasn't until after 6pm he had a drink - throughout his stay on ward 11 he had been given morphine based Tramadol as pain relief and the dosage had been increased to suit his pain but as he had not been eating or drinking he was slowly being overdosed as no one had bothered to check his stats at all. This is unacceptable and a complaint has been raised.
