Government inspectors from the Care Quality Commission made an unannounced inspection at Jasmin Court Nursing Home on Roe Lane in Pitsmoor in October this year.
The home was found to be failing to provide care which was safe, effective, or well led, while three of the five national standards of care were not being met.
Inspectors found three breaches of the Health and Social Care Act.
The report said: “We found the main toilet used for people who required a hoist for moving and handling was not suitable for purpose.
“There was also no call bell in this toilet for people to call for assistance.
“It had failed to identify breaches and concerns identified by the Commission in previous inspections, and this one, including areas where the premises were in a poor condition, medication errors, staff failing to support people in a safe manner and poor infection control arrangements.
“This meant that the provider did not have sufficient systems in place to monitor the quality of the service.”
Staff praised for being caring and responsive and residents told inspectors that they liked living at the home.
Omar Ahmed, administration manager for Sage Care Home Ltd, said changes have already been made.
He said: “We’ve hit a few snags but we’re working hard to address them and we have also submitted our action plan ready for the inspectors to come again.
“Residents at Jasmin Court have served their countries and their care is my paramount concern.
“We’ve got a new manager in place and everything is good to go.”
Debbie Westhead, CQC’s Deputy Chief Inspector for Adult Social Care, said: “People are entitled to services which provide safe, effective, compassionate and high quality care.
“If that is what we find on inspection – we give the service a rating of good, or outstanding.
“If we find that a service requires improvement, we will expect them to provide us with a full plan setting out how they will address the issue.
“We will share our findings with local commissioners, and we will return in due course to check that they have made the required improvements.”
