'No criminality' in Perth aged care deaths

West Australian police have found no evidence of criminality in the deaths of two residents at an aged care home in Perth.

Major crime detectives reviewed the deaths while probing allegations of abuse at the Regis Aged Care facility in Nedlands.

WA Police on Friday said it had finalised its investigation into the deaths and recent assault complaints, and had found no evidence of criminal behaviour.

The residents' families have been advised and police will prepare reports for the coroner.

Regis wrote to families last week advising them it had received allegations of rough handling of residents, failing to support and promote their privacy, dignity and independence, and inappropriate communication between staff and residents.

The allegations were made by students who were at the site from January 11 to 14.

The Aged Care Quality and Safety Commission conducted a surprise visit to the facility on January 20 and found that it was not providing care consistent with national standards.

It imposed sanctions on the centre removing federal government funding for new admissions for the next six months and requiring Regis to provide staff training and appoint an adviser to oversee the compliance with requirements.

Among the concerns identified were allegations of sexual assaults, rough handling and deficiencies in areas including pain management, wounds, falls and challenging behaviours.

Regis said it had received allegations about the care of two residents on January 13 and had stood down a staff member pending an investigation.

It received further allegations about the care and treatment of residents on January 15, with 17 mandatory reports involving 14 residents lodged with WA Police.

The families of the residents were contacted and Regis arranged for registered nurses and general practitioners to assess all residents.

Regis has commissioned its own investigation and promised to share the findings with families when available.

"Although the allegations aren't yet substantiated, we take them very seriously and apologise for any distress caused," the aged care provider told families.

"The management and team members at Regis Nedlands are deeply saddened that any resident may have received anything less than the professional, compassionate care we seek to deliver to every resident, every day."
