"Incompetent"

My 86 yr old dad -in law was taken in last week with urine retention. Two days later we received a call from social services to state he will be discharged the following day with a catheter inserted. Although my husband explained he would have no capacity to change the bag SS disagreed and we received a call at 10pm to tell us to pick him up! 1am my dad in law was on the telephone crying that he was in pain and the bag was full. My husband had no idea what to do so took him back to Queens. It took emergency staff two and a half hours to empty the bag and then sent him home again. I called the ward to ask why the catheter had been placed, what tests had been carried out, what care plan had been put in place and where was the discharge paperwork. No member of staff could answer but said they would call back with the info. We're still waiting 5 days later! Every night since his discharge we have been called to his home because the bag is full and he is in pain and last night the bag had leaked so he woke in tears soaking wet! They have treated my old vulnerable dad in law like a piece of meat and they talk about safeguarding! They have not listened to our concerns regarding his capacity just concerned about the bed status! Disgusted
