MR WILLIAMS' sister welcomed the words of Dr Emma Carlyon, Coroner for Cornwall.
Dr Carlyon said she will be writing to Cornwall Council and others involved with Mr Williams following the inquest into his death.
Mr Williams' sister, Lynn, said the coroner's actions were a positive step but she still believes the standard of care fell below an acceptable level. She is taking legal advice as to her next steps.
Lynn believes her brother was failed because of prejudice and because his alcoholism was not recognised as a mental illness.
Paying tribute to her brother she said he was "a good man," who "did nobody wrong" and he had been a community fireman in St Austell.
In December she said her brother called his doctor to ask for a home visit because he was unable to walk as a result of his cellulitis.
But she claims he was told to attend the surgery and it was not until he rang again two days later that he was visited and admitted into hospital. He returned home with no support, could not manage and was confused by different medications.
He returned to hospital and was told both his feet might need to be amputated, Lynn told the Cornish Guardian.
She added: "He was ashamed but he had nothing to be ashamed of; he was ill."
