George McNamara, head of policy and public affairs at the Alzheimer's Society, said:
These findings point to a worrying lack of awareness and understanding of the use of DoLS.
It is unacceptable that the majority of care providers are not following correct procedure when using this measure.
Over half the applications were for someone with dementia and much more needs to be done across health and social care to ensure DoLS are better understood and implemented consistently, ensuring the best possible quality of care and support.
It is essential that the CQC continue to monitor its use to protect those most vulnerable in society.
