Inspectors from the Care Quality Commission carried out an unannounced inspection at Hillcroft Nursing Home in Caton Green Road, near Lancaster.
The watchdog has taken enforcement action against the home over its staffing levels and providing care and support to meet people’s needs.
The home has also been ordered to make improvements in its management, treating people with respect and protecting people from harm.
The home said immediate steps were taken following the inspection to resolve the problems.
It did meet the expected standards in relation to record keeping, safety of the premises, supporting workers and safeguarding users from abuse.
The inspection was carried out in February but a 33-page report from the CQC was only published last week.
The CQC said: “As a result of the inspection, CQC has issued two formal warnings to the provider requiring improvements in relation to care and welfare of people who use services, and staffing.
“The home must also take action to address shortfalls against the additional three standards that are not being met.”
Its report added: “We found that people’s views and experiences were not always taken into account when planning and carrying out care.
“Most care records we looked at had all the necessary information to support people effectively. We had concerns about the cleanliness of The Manor Unit. There were not enough staff on duty, to support people safely and to provide meaningful activities.”
John Ayrton, managing director of Hillcroft Nursing Homes, said: “ Immediate steps were taken to remedy the issues raised during the inspection and we continue to work closely with the appropriate authorities to ensure that the care provided to all our residents at Hillcroft is consistently of the highest possible standard.”
Four care workers from Hillcroft nursing home in Slyne-with-Hest were jailed in January for abusing elderly residents. Residents were mocked, bullied and tormented because they would have no memory of the abuse.
The CQC announced then it was planning “major changes” to the way care homes are inspected.
