A nurse has vowed never to allow another family member to be treated at Croydon University Hospital after witnessing a catalogue of errors when her grandmother was admitted to the hospital.

Leila Grebovich has condemned the nursing and medical care at the hospital and said she fears elderly patients and their health are being unnecessarily put at risk.

The 22-year-old who works at King's College Hospital said the care her 83-year-old grandmother Linda Coulson received after being admitted to the hospital left her “angry and disappointed”.

Her complaint follows a shock survey published last year that found nearly a third of staff at Croydon Health Services Trust, considered standards so poor they would not want friends or family to be treated there.

Just 30 percent of doctors, nurses and clinical workers said they would trust Croydon's health services, making it the worst ranked in the country in the 2011 survey.

Results of the 2012 staff survey published last week, revealed 41 percent of staff would be happy to have a relative or friend treated at the hospital.

Mrs Coulson, who lives in Arkell Grove, Upper Norwood, was admitted to Wandle ward 1 on February 6, following an eight-hour wait in the accident and emergency department.

When Ms Grebovich visited her grandmother the following day she found her distressed and tearful.

She said: “She told me she had been woken at 4am by two nurses who asked her to get out of the bed and into a wheelchair.

“She complied and was then taken to another ward and left in a side room. She tried to ask where they were taking her, but did not get an answer.

“My grandmother was so upset and tearful at being moved the nurses eventually brought her back to the previous bed.

“It is disgusting staff felt it was acceptable to wake an 83-year-old in the early hours of the morning and attempt to move her with no explanation.”

Ms Grebovich said she noticed a series of failings on subsequent visits to the hospital, including her grandmother’s drug chart stating she had no allergies – when she is allergic to Penicillin – and finding unidentified medication next to her gran’s bed that had to be thrown away.

She said: “I found another patient’s notes in my grandmother’s folder and her bowel chart had not been filled in for two days, even though she was admitted to hospital with a colorectal problem.

“If the patient is not going to be correctly monitored, what is the point of her being in hospital?”

Ms Grebovich said: “I was just horrified, I will never again allow her or any of my family members to be treated at Croydon University Hospital.

“I am not slagging off my fellow nurses, but they [the hospital] need to be aware what is happening on the wards.”

A spokesman for Croydon NHS Trust said: “We are aware Mrs Coulson’s family were not happy with aspects of her care while she was a patient.

“Staff on the ward acknowledged and apologised for some of the shortcomings of care at the time, but the matron and the associate director of nursing are looking into all aspects of Mrs Coulson’s stay and will be responding to the family as soon as possible.”
