Summary

This study compared two pressure-reducing surfaces for orthopaedic patients. Both surfaces provided similar comfort levels, but initial equipment setup was problematic.

Area of Science:

  • Orthopaedic patient care
  • Medical device evaluation
  • Pressure ulcer prevention

Background:

  • Pressure ulcers (bedsores) are a significant concern in orthopaedic patients.
  • Effective pressure-reducing surfaces are crucial for preventing skin breakdown.
  • Evaluating patient comfort and equipment usability is essential for clinical adoption.

Purpose of the Study:

  • To compare the effectiveness of two dry-flotation pressure-reducing surfaces (Roho mattresses and Sofflex mattresses) in orthopaedic patients.
  • To assess pressure sore incidence and patient comfort.
  • To evaluate the appropriate use and initial setup of the equipment.

Main Methods:

  • A randomized controlled trial involving 100 orthopaedic patients.
  • Comparison of Roho mattresses and Sofflex mattresses, supplemented with Roho Quatro cushions.
  • Assessment of pressure sore incidence, patient-reported comfort, and equipment usability.

Main Results:

  • A low incidence of pressure sores was observed in this high-risk group, precluding a definitive comparison of mattress effectiveness.
  • Both Roho and Sofflex mattresses were found to provide similar levels of patient comfort, with most patients reporting satisfaction.
  • The initial setup and adjustment of the pressure-reducing equipment were identified as unsatisfactory.

Conclusions:

  • Both evaluated dry-flotation pressure-reducing surfaces appear equally effective in providing comfort for orthopaedic patients.
  • Further research is needed to determine the comparative effectiveness in preventing pressure sores due to the low incidence in this trial.
  • Improvements in the initial setting and user training for pressure-reducing equipment are recommended.
