B.C.'s health minister says Vivian Fitzpatrick was escorted to a taxi by a nurse and her caregiver was notified before being discharged from Delta Hospital at 2:30 a.m. PT, contradicting claims made by the legally blind 90-year-old's daughter.

"The patient had a 24-hour care provider who was alerted... it's a five-minute taxi ride, and a nurse was with the person for the entire time, and was assessed by a doctor," said Terry Lake.

"I'm telling you what the nurses, the doctors at the facility said."

Fitzpatrick's daughter Paddy Munro was incensed, saying she couldn't believe the health minister would defend the hospital without speaking to the family. 

"Instead of listening to the people who are under the gun, he's listening to [the Fraser health unit], not to the people," she said.

"[Lake] said, 'Oh, he had heard that my mother was not left by herself, that a nurse had helped her out to the taxi, and that is was OK with the caregiver, which was not. It was not," Munro said.

"Why would he not come and ask us?"

Munro said her mother has been having nightmares and hasn't had a good night's sleep for two nights.

Meanwhile, B.C. NDP leader Adrian Dix says it is disrespectful for the Fraser Health Authority to insist it did nothing wrong.

"What you need is someone who has some independence on these matters," Dix said. "To look at things with an open mind, and to draw some conclusions that can give comfort to the family in this case and allow the health authority to move past the issue in a credible way, which means learning lessons and making changes."
