Higher specification foam mattresses can reduce pressure ulcer incidence in at-risk individuals. While some pressure-relieving overlays show promise, evidence for other devices remains unclear, necessitating further research.

Area of Science:

  • Wound Care
  • Medical Device Efficacy
  • Preventive Healthcare

Background:

  • Pressure ulcers (bedsores) are localized tissue damage from pressure, shear, or friction, common in the elderly and immobile.
  • These ulcers incur significant financial and human costs.
  • Pressure-relieving support surfaces are standard preventive aids in healthcare settings.

Purpose of the Study:

  • To evaluate the effectiveness of pressure-relieving cushions, beds, mattress overlays, and replacements in preventing pressure ulcers compared to standard surfaces.
  • To compare the efficacy of different pressure-relieving surfaces against each other for pressure ulcer prevention.

Main Methods:

  • A systematic review of randomized controlled trials (RCTs) published or unpublished, assessing pressure ulcer prevention devices.

Related Experiment Videos

  • Included studies reported objective clinical outcomes like pressure ulcer incidence and severity.
  • Data from 41 RCTs were extracted, and results were synthesized, with meta-analysis where appropriate.

    • Main Results:

    • Higher specification foam mattresses reduced pressure ulcer incidence in at-risk individuals.
    • Pressure-relieving overlays on operating tables decreased postoperative pressure ulcer incidence.
    • Evidence for alternating pressure devices, seat cushions, and some specialized overlays remains inconclusive or suggests potential harm.

    Conclusions:

    • Higher specification foam mattresses are recommended for individuals at high risk of pressure ulcers.
    • Pressure relief in the operating theatre may reduce postoperative pressure ulcer incidence.
    • The effectiveness of advanced pressure-relieving technologies and devices for specific settings (e.g., A&E) requires further rigorous evaluation.
