Pressure-reducing surfaces are linked with a significantly lower incidence of heel ulcers than standard hospital mattresses, according to Canadian researchers.
Foam mattresses also significantly reduced the risk of heel ulcers developing, they said after reviewing 14 studies involving 1,457 patients.
The authors said: 'There is evidence to support the use of certain air or foam mattresses/overlays in the prevention of heel pressure ulcers when compared with a standard hospital mattress.
But they added: 'There is insufficient research available at this time to determine if heel-protective devices can prevent heel pressure ulcers.'
