The independent inquiry into failures at Mid Staffordshire Foundation Trust has highlighted weaknesses in hygiene practice among staff.
It said it had received evidence that included complaints of staff using a razor on more than one patient and the use of a shared bowl for washing.
The inquiry also heard several accounts of poor mouth care, where mouthwash was not provided for patients with mouth ulcers and teeth cleaning and rinsing of dried mouths was neglected.
The report said: “Failure to ensure a proper level of personal cleanliness and hygiene degrades patients, aggravating the feelings of illness, disability and separation from home and familiar surroundings.
“A wholly unacceptable standard was tolerated on some of the trust’s wards for a significant number of patients.”
