Workers at a Saskatchewan seniors home at the centre of a debate around care standards say they haven't noticed any changes since the death of a resident.

The three care aides, brought to the legislature by the Opposition NDP, say the Santa Maria Senior Citizens Home is understaffed and residents don't receive proper care.

Last week, the New Democrats brought to light the death of 74-year-old Margaret Warholm, who lived at Santa Maria until October 2013.

Medical records show that Warholm reported losing 30 pounds in a year and had compression fractures in her vertebrae.

She also had a large bedsore on her back that her family believes could have been prevented.

Health Minister Dustin Duncan asked that the ombudsman look into the death and to examine whether provincial guidelines were followed.
