The party's health spokeswoman Alison McInnes said: "The public will be shocked that people are still dying from bed sores in the 21st century. They cause huge amounts of pain and discomfort but are easily preventable.
"Bed sores can arise because a patient has been left alone by staff for hours at a time. It is inexcusable and cannot be allowed to continue.
"The Scottish Government must tackle this and treat bedsores as seriously as hospital infections."
A Scottish Government spokeswoman said: "The Scottish Government is working with nurse directors across Scotland to ensure there are no avoidable hospital-acquired pressure ulcers by December 2015.
"In addition, we have developed a package of measures to minimise the risk of pressure ulcers, a Clinical Quality Indicator (CQI) for Pressure Area Care, a Practice Development toolkit and other educational resources, which are being used by NHS Boards, resulting in standards of care being driven up across the country."
