Alice Cameron says she is suffering sleepless nights and anxiety after her sister Marion, who is from Linwood, went missing from Dyekbar Hospital for the fourth time within a matter of months.

The 32-year-old, who relies on regular medication, had been receiving treatment at the Grahamston Road facility when police launched several appeals after she was reported missing.

Fortunately, on each occasion she was found safe and well. But worried sister Alice — who is Marion’s next of kin — has now raised questions over security measures at the Paisley unit.

Mum-of-three Alice, from Kirklandneuk Road in Renfrew, said: “I’m at my wits end, last week was the fourth time Marion went missing and this time she managed to get to London.

“What I can’t understand though is how this has been overlooked yet again. I’ve phoned Dykebar and sent complaints to the NHS. But I haven’t heard back about what is going on.

“My life has been put on hold because Marion isn’t been looked after properly. I’ve had to give up my job in case the police phone to tell me she has gone missing again.

“I was told by a nurse none of the cameras in Dykebar work. I’m completely shocked with the failings and negligence of Dykebar.

“They have a duty of care and I feel they have failed Marion miserably. I want answers.” The first time hospital patient Marion was reported missing was in December last year and her most recent disappearance was last weekend.

On one occasion, when Marion went missing on February 2 last month, Police Constable Barry Gourley described Marion’s disappearance as “very concerning.” Her sister Alice feels a closer eye should be kept on the patients and that they should be accompanied by another adult or nurse at all times.

She said: “Marion is such a timid, intelligent and beautiful young woman and it’s horrible to have to worry that she might go missing again.

“The worst scenarios always go through your head when something like this happens as Marion is obviously vulnerable.

“I’ve cried myself to sleep so many times but I’m concerned that, if she goes missing again, it will be a ‘the boy who cried wolf’ situation and people will be less likely to try and help look for her.

“I just want a straight answer from Dykebar as I feel they’re giving me no information about my sister’s safety.” In April last year, health chiefs were also ordered to remove plastic bin bags from mental health wards after the death of a woman at Dykebar Hospital.

Safety watchdogs demanded that NHS Greater Glasgow and Clyde ban the bags after a 27-year-old was the second patient to commit suicide using the item.

A spokeswoman for NHS Greater Glasgow and Clyde said Dykebar Hospital has two open Adult Acute Admission Mental Health Wards.

She added: “As part of a patient’s care and treatment time out of the hospital can be agreed with the multi disciplinary care team and individual patients. Unfortunately there are times when patients who have agreed time out fail to return as agreed.

“If the patient’s family have any complaints we would be happy to meet with them to discuss their concerns.”
