A Northumberland GP practice has been told it will be put into special measures if it does not improve.
Widdrington Medical Practitioners has been given the warning as part of a new inspection regime.
The CQC said the priority was to help practices improve and that surgeries would be closed only if it was “absolutely necessary”.
The service was rated inadequate for being safe and well-led, and good for being caring, responsive and effective.
Out of those inspected, three GP practices have been placed in special measures.
Professor Steve Field, chief inspector of General Practice, said: “So far we have published ratings on 143 practices – of which the vast majority have been Good or Outstanding.
“It is disappointing that we have found any to be Inadequate, but it is important that those practices are offered help at the earliest opportunity to improve.
“In each case, we have found significant areas of concern.
“Patients should be able to expect high quality and consistent care from their GP which is why I have put the three practices into special measures.
“Two practices have already begun to show signs of improvement but we will monitor their progress closely, returning to inspect in the near future.”
