Summary

This study found that while both pressure-relieving systems showed no significant difference for non-heel ulcers, one system significantly improved heel ulcer healing. Extra equipment reduced pressure ulcer incidence in hospitals.

Area of Science:

  • Medical Technology
  • Clinical Nursing
  • Wound Care

Background:

  • Pressure ulcers pose a significant challenge in acute hospital settings, particularly for elderly patients.
  • Effective pressure-relieving systems are crucial for preventing and managing these debilitating conditions.

Purpose of the Study:

  • To compare the efficacy of two distinct pressure-relieving systems in high-risk patients.
  • To evaluate the impact of additional pressure-relieving equipment on reducing pressure ulcer incidence.

Main Methods:

  • A randomized controlled trial involving 141 high-risk patients (Waterlow score) in a care-of-the-elderly unit.
  • Group A: Huntleigh Nimbus 3 with Aura cushion; Group B: Pegasus Cairwave Therapy System with Proactive 2 Seating cushion.
  • Outcomes assessed via visual inspection and photographic records.

Main Results:

  • No statistically significant difference between systems for non-heel ulcers or overall improvement.
  • Significant improvement in heel ulcer healing observed in Group A (P = 0.019).
  • Hospital-acquired pressure ulcer incidence decreased from 0.2% to 0.13% during the trial.

Conclusions:

  • Different pressure-relieving mattress products demonstrate varying efficacy, particularly for heel ulcers.
  • Availability of extra pressure-relieving equipment can effectively reduce hospital-acquired pressure ulcer incidence.
  • The tested systems did not significantly influence patient length of stay.
