An unannounced inspection at Guthrie Court Care Home in Edinburgh found previous requirements for improvement in areas including staff supervision had not been met.
The home, run by Four Seasons Health Care, was graded as "weak" and "unsatisfactory" in all areas of the inspection in the report published by the Care Inspectorate - the independent body which scrutinises care services in Scotland.
Inspectors said they did not find any "significant improvement" in the quality of care for residents or the environment when they attended the home in March since their earlier visit in October last year.
After the first visit, ten requirements were made but only three had been fully met at the home, which provides nursing and residential care for older people. Some positive interactions between staff and residents were noted and a new temporary manager had been appointed. But inspectors continued to have "concerns" about the environment, personal plans, privacy and dignity as well as infection control and staff training and supervision at the home in the Liberton area of the city.
