On Monday, CBC News shared hidden camera footage showing a male patient pulling 89-year-old Eileen Adamson out of her bed at the home run by CapitalCare, a wholly-owned subsidiary of Alberta Health Services.

Staff at the centre told Adamson’s daughter, Susan Carter, that her mother had fallen out of bed. But Carter learned the truth when she reviewed footage from the camera she had set up last summer, because she was worried the man had a history of wandering around the facility.

After that incident, Carter looked through more video footage and found other incidents that shocked her.

'Gruff' scolding, arm grabbing

On Dec. 7, 2014, the camera captured two workers at the centre trying to get Adamson into her bed using a hoist.

In the video, one worker berates the senior as she is being lifted.

At one point, Adamson appears to be pleading to be allowed to sit down.

"Stand up! Hold!" the worker says as she grabs and shakes Adamson's arm.

"She is very rough, gruff … that is not a way to treat an elderly lady," Carter said after watching the video.

Lights out, camera turned away

"That's disgusting, it's unacceptable ... no one would want their mother spoken to that way and treated that way."

Staff at the Kipnes Centre were told about the video last week.

Since then, some workers have turned out the lights whenever they are working in Adamson's room.

Another video shot later, in the dark, shows a worker turning the camera away from Adamson's bed so it can't record what's happening.

"I immediately thought, 'Well, one of the staff has sabotaged us here,'" said Carter, who has become increasingly worried for her mother's safety.

"I'm not sure she's safe anywhere."

Investigations underway

Deb Gordon, a chief health operations officer with Alberta Health Services, said an investigation is underway into Adamson’s treatment. It is expected to last a couple of weeks.

"We expect our staff to treat everyone with dignity and respect," she said.

The sentiment was echoed by Iris Neumann with CapitalCare, which runs the home.

"The behaviour exhibited in that video is not what we approve of in CapitalCare. It's not what we teach, it's not what the schools teach health-care aides," she said.

Neumann said the two staff members who appeared in the hoist video are not working for CapitalCare while the AHS investigation is underway.

Meanwhile, Protection of Persons in Care, the official government body that investigates alleged abuse in care homes, is also conducting its own investigation into the situation. That investigation is expected to take significantly longer.

"It’s not the way people should be taken care of'

Alberta Health Minister Stephen Mandel spoke out about the video on Tuesday, calling the footage "very distressing."

"It's not the way people should be taken care of."

Mandel said the province is in the midst of setting up new standards and an oversight agency that will "have teeth" in ensuring that quality care standards are met. That announcement is expected in a few weeks, he said.

"We need to make sure we’re more diligent and that people are safe and secure in our hands."

Mandel also said the Kipnes Centre has a good reputation overall, and that the actions of the individuals in the video was "an isolated incident" and does not adequately reflect the thousands of others who work in the care industry.
