Bosses at Stafford Hospital have apologised after a nurse has been struck off the nursing register for failing to recognise a patient was diabetic.
Ann King failed to check Gillian Astbury's notes or check her blood sugar levels.
The 66-year-old died in April 2007.
King's colleague, Jeannette Coulson, was given a caution order for three years by the Nursing and Midwifery Council.
"Neither of these two nurses works for the Trust - Jeanette Coulson left in August 2010, and Patricia King in August 2012.
"Our thoughts remain with the family and friends of Gillian Astbury and we apologise for the appalling care Ms Astbury received at our hospital in April 2007."
