A vulnerable woman with a brain tumour and intravenous tube attached to her was allowed to leave hospital without staff noticing, her husband has said.
Julia Dutton, 63, who has a pituitary gland tumour, was being treated at Wrexham Maelor Hospital.
Husband Alan Dutton, 60, found her in the hospital car park with the cannula after she asked him to collect her.
“I spoke to the nurses and I said, ‘you can’t just let a vulnerable patient walk out, she’s in your care. This is not good enough’,” he said.
Alan Dutton later discharged his wife because he was “too fearful” to leave her there unattended.
Betsi Cadwaladr health board said ensuring patients felt “well cared for “was its “primary concern”.
The failing health board, which covers all of north Wales, has been under special measures for the past nine years.
Julia Dutton, from Burton near Wrexham, was being treated for dehydration at the hospital.
The tumour, diagnosed last month, effects her ability to recognise when she needs to eat and drink, leading to several emergency admissions. She also suffers from anxiety.
Alan Dutton said: “She rang me to say, ‘I’ve had the drip, I am coming home’.
“I literally jumped in the car, drove to the hospital and I found her standing outside A&E with her bag ready to come home,” he said.
But then he saw the cannula and realised his wife had not been discharged.
She was returned to a treatment room and put back on fluids before being moved to an observation unit.
Alan Dutton stayed with his wife through the night and following day because he was concerned she was not being properly monitored.
He said there were long periods when staff did not check on her.
“There weren’t enough nurses, there weren’t enough healthcare assistants and there weren’t enough beds,” he said, adding management issues were to blame, saying they seemed to be in a “vicious circle”.
Alan Dutton decided to “get her out” of hospital after his wife had eaten.
