Hello Tezzy08, it's very easy to complain, I've just done it myself in respect of my husband and his death which was aggravated by his time in hospital.  So it really depends on what you want from complaining, acknowledgement of how she was treated, lack of care, medical negligence, there are numerous ways of achieving this.  Firstly I saw a solicitor, who did not charge me anything and gave me excellent advice on how to proceed.  I really just want an apology and someone to acknowledge that the care was way below what they should have offered.  Look up the chairman of the Trust, also look for other names of those in charge, all this is on the website of that Trust.  If you kept a note of Mum's tiine and treatment whilst in hospital, then write that down and ask questions for each point you raise.  You can email and send copies of your complaint to all of them. They then have up to 40 days to reply after investigation of your complaint.  They may ask to meet with you, if they do take someone with you, the meeting will be recorded and you will receive a disc of this for yourself.  I hope this helps a little in clearing your mind and achieving your aims.  Good luck, Carol x
