Alternating pressure mattress replacements and overlays show no significant difference in preventing new pressure ulcers. However, mattress replacements are more cost-effective, reducing overall healthcare expenses and delaying ulcer development.

Area of Science:

  • Medical Devices
  • Wound Care
  • Health Economics

Background:

  • Pressure ulcers pose a significant challenge in healthcare settings, impacting patient well-being and increasing costs.
  • Alternating pressure surfaces are commonly used to prevent and manage pressure ulcers.
  • Comparative effectiveness and cost-effectiveness of different alternating pressure surfaces require rigorous investigation.

Purpose of the Study:

  • To compare alternating pressure overlays and replacement mattresses regarding new pressure ulcer development, healing, patient acceptability, and cost-effectiveness.
  • To assess the impact of pressure ulcers on patients' overall well-being.

Main Methods:

  • A multicenter, randomized, controlled trial involving 1972 patients aged 55 years and older.
  • Patients were randomized to alternating pressure overlays or replacement mattresses.

  • Qualitative study and focus groups explored patient well-being and clinical experiences.

    • Main Results:

    • No statistically significant difference in new pressure ulcer development (10.7% overlay vs. 10.3% replacement).
    • Alternating pressure mattress replacements were associated with lower overall costs and delayed ulceration.
    • Higher patient dissatisfaction and difficulties with movement reported with overlays.

    Conclusions:

    • Alternating pressure mattress replacements are recommended for procurement due to cost-effectiveness, with no increased risk of pressure ulcer development.
    • Patient preferences for overlays can be accommodated if replacements are unavailable or if patients request them.
    • Further research should compare mattress replacements with high-specification foam mattresses and investigate costs in higher-risk groups.
