Conservative health spokeswoman Mary Scanlon has called for the Scottish government to review the funding for care provision for older people.
Ms Scanlon was debating the differences in care home costs amid warnings over the impact on the sector of an ageing population on 18 November 2010.
She expressed concern about the wide disparities which existed between different service providers with regard to fees and costs.
The average local council cost per place per week for non-nursing care is £800 and the equivalent cost for a place under the National Care Home Contract in the independent sector is £480, according to the Scottish Care Manifesto.
Public Health Minister Shona Robison said she would ensure "contributions to the debate fed into Reshaping Care For Older People", the Scottish government's public engagement process on care for the elderly.
Ms Scanlon's amended motion was unanimously passed at decision time.
