Niyimbona's family filed a lawsuit against the hospital over accusations of neglect and medical malpractice.
Preventative and safety measures to help protect and monitor the girl were reportedly removed from her room before her death, including round-the-clock video and a health care worker, or 'sitter,' assigned to her room, Investigate West reported.
There was also an alarm on her door to notify hospital staff if she opened her hospital room door.
According to the lawsuit reviewed by the outlet, the hospital 'failed to properly utilize and monitor alarms in Sarah's room allowing her to escape.'

'I feel like they neglect my daughter and they neglect me. I feel like they were tired [of] seeing Sarah there, so they didn't care about looking after her all the time,' Gertrude told the Spokesman-Review.
The fifteen of the nurses fired from the hospital were let go for 'patient privacy violations,' the hospital said.
'It's heartbreaking that the one place that was supposed to keep her safe failed to do so,' said Niyimbona's sister, Asha Joseph
Nurses at the hospital were accused of improperly accessing the girl's health records after her death for no medical purposes


The nurses were accused of improperly accessing Sarah's health records after her death for no medical purposes, the Spokesman-Review reported.
'Providence takes violations of our code of conduct and federal privacy laws that govern private health information very seriously. We review employee conduct and take appropriate action, including termination of employment, where warranted. Patient privacy is one of our top priorities,' hospital spokesperson Jen York told the outlet.
Bobbi Nodell, a spokesperson for the Washington State Nurse Association union, said that the violations could have been as simple as 'hovering' over the girl's chart from 'concerned nurses who worked with that patient.'
