NHS Grampian had the highest number of patients who died waiting to be discharged from hospital in Scotland last year.
Delayed discharges happen when a patient is fit to leave hospital but cannot, usually because a care home bed is not available or adjustments to their own home or care package have not been made.
Health Minister Shona Robsion pledged to eradicate delayed discharge by the end of 2015 and hoped new Integrated Joint Boards (IJB) – partnerships between councils and health boards – would help fix the problem.
But NHS Grampian recorded 73 deaths in 2016 – about a quarter of all 291 deaths linked to delayed discharge in Scotland.
Scottish Labour health spokesman Anas Sarwar said: “This shows delayed discharges are not just detrimental to patient flow and the running of our hospitals, but they can be seriously dangerous for the patients involved.”
An NHS Grampian spokeswoman said delayed discharge was “frustrating” for everyone involved.
She added: “The IJB, bringing health and local authority teams even closer together, aim to provide a seamless response to the health and social care needs of people in Grampian.
“All areas have action plans which deal with short, medium and long-term approaches to delayed discharge.
“It must be stressed there is no quick fix for this issue and we continue to work closely with the three local partnerships.”
Aberdeenshire Health and Social Care Partnership chief officer Adam Coldwells said delayed discharge was a top priority and had reduced by 34%.
