The Care Quality Commission has begun its inspection of the Cumberland Infirmary and the West Cumberland Hospital this morning.
The hospitals are under extra scrutiny after they were placed in special measures last year, because of higher than average death rates.
The inspectors are holding two public events this evening at 6:30pm in Carlisle's Hallmark Hotel and at Whitehaven Golf Club.
A Cumbrian Hospital Trust is urging patients who have concerns about their care to speak to their staff in the first instance so problems can be resolved.
It follows an incident at West Cumberland Hospital where a stroke victim was sent home as there was no specialist bed available.
The incident was revealed along with three other different situations at the monthly board meeting of North Cumbria University Hospitals NHS Trust.
It runs the Whitehaven hospital and the Cumberland Infirmary in Carlisle.
A spokeswoman for the North Cumbria University Hospitals NHS Trust has responded to the findings of a NHS report that a stroke victim was sent home from a Cumbria hospital by a doctor because "no stroke unit was available."
A stroke victim was sent home from a Cumbria hospital by a doctor because "no stroke unit was available", according to an NHS report.
The patient was discharged by a locum doctor from one of the hospitals run by North Cumbria University Hospitals NHS Trust, according to the trust's board papers.
An investigation has been launched by the trust's medical director into the process for appointing agency locum medical staff.
The locum in question no longer works at the trust, according to the document.
There were also three other "serious" patient incidents during June at the trust, which runs Cumberland Infirmary in Carlisle, the West Cumberland Hospital in Whitehaven and a midwifery-led service at Penrith Community Hospital.
One patient was operated on after mistakenly being given a local instead of a general anaesthetic.
Medics missed a "mass" which should have been spotted on a chest X-ray of another patient.
And a consultant coughed during a procedure which resulted in a patient moving - which they claimed "affected the clinical outcome".
The trust is one of 11 that was put put into "special measures" for "fundamental breaches of care" following a review into 14 trusts with higher than expected death rates.
The investigation, led by NHS medical director Professor Sir Bruce Keogh, found that none of the hospitals investigated was providing "consistently high-quality care to patients".
Concerns have been raised over consultant cover on weekends at hospitals in North Cumbria.
According to a new report, North Cumbria University Hospitals NHS Trust has had as few as four consultants on duty on a Saturday and Sunday to cover 485 patients and two accident and emergencies.
Jeremy Rushmer, Interim Medical Director at the trust, said: "Surgery in North Cumbria is run as an on-call service with consultant surgeons available in all sub-specialties 24/7 as opposed to a 'shift system'.
"This allows complete cover over a longer period of time with the limited consultant workforce available.
"This is the standard approach nationally and we comply fully with all Royal College of Surgeons and Association of Surgeons guidelines and recommendations."
A leading cancer nurse at North Cumbria University Hospitals has won a national award in recognition for her outstanding contribution to cancer nursing.
Consultant Cancer Nurse Helen Roe was awarded the 'UK Oncology Nursing Society's President's Award', an award only given out bi-annually.
The prestigious award acknowledges the work Helen has done throughout her nursing career, and in particular, since she became one of the UK's first Consultant Cancer Nurses 11 years ago.
Judges highlighted specific attributes in choosing Helen for the award, including her work on online learning modules, her involvement in the development and publishing of position statements, and her various publications on cancer nursing.
