Evidence summaries

Level of evidenceEvidence statement
1++All pressure-relieving support surfaces: No conclusive research evidence to indicate which pressure-relieving support surfaces are most effective in the treatment of pressure ulcers.
1+Air-fluidised therapy: some evidence from meta-analysis of two trials indicate that ulcer healing was improved compared to modified AP and a range of other CLP supports in adults with grade 2–4 pressure ulcers (conventional therapy).
1+Low air loss therapy: no evidence of a difference for complete ulcer healing found when compared to foam mattress overlays in individuals with grade 2–4 pressure ulcers.
1++Alternating pressure therapy: no evidence of a difference in complete ulcer healing found comparing different alternating pressure support surfaces.
No evidence of a difference found compared to static fluid overlay mattresses or cushions in the elderly with grade 2 or greater pressure ulcers.
1+Continuous low pressure therapy: no evidence of a difference in ulcer healing rates for water-filled mattresses compared with foam replacement mattresses in adults with grade 3 pressure ulcers. Limited evidence of difference in ulcer healing for profiling beds compared with standard hospital beds in adults with grade 1 or greater pressure ulcers.
