Title: Methods for Pressure Ulcer Prevention


1
Methods for PressureUlcer Prevention
  • Jeremy Doody
  • Biomedical Engineering 2018
  • 10/6/15

2
What is an Ulcer?
  • Also known as pressure sores or bed sores
  • Occurs on bony area of body (ex hip)
  • Damage to skin and tissue
  • Elderly/bedridden people are more succeptable
  • 4 stages of Ulcers

3
Solutions
  • Detect and treat as early as possible
  • Dressings (bandages)
  • Topical Agents
  • Turning to elleviate pressure spots
  • Cleanliness

4
Comparing Topical Agents with Placebo
  • Houwing study
  • 4 week study split patients into 3 groups
  • Intervention group- 29 patients given DMSO-cream
    every 6 hours
  • Placebo group- 32 patients given a fake cream
    every 6 hours
  • Control group- 18 patients given no cream
  • All groups changed their lying position by 30
    degrees every 6 hours

5
Results of Study
  • 62.1 got ulcers in the intervention group
  • 31.3 got ulcers in the placebo group
  • 38.9 got ulcers in the control group
  • Effectiveness based on risk ratio (RR)
  • There was no statistically significant
    difference in pressure ulcer incidence between
    the intervention and the control group (RR 1.60,
    95 CI 0.84 to 3.04).
  • There was no statistically significant
    difference in pressure ulcer incidence between
    the placebo and control group (RR0.80, 95 CI
    0.37 to 1.74).
  • There was a statistically significant difference
    in pressure ulcer incidence between the
    intervention and the placebo group (RR 1.99,
    95 CI 1.10 to 3.57).

6
Dressing vs. No Dressing
  • Kalowes study
  • This study followed up participants while in the
    intensive care unit
  • average length of stay was 6.5 days (range was 0
    to 120 days)
  • Intervention group- 169 patients had a dressing
    applied to the skin covering the tailbone area
  • Control group- 166 patients had no dressing
    applied.

7
Results of Study
  • Intervention group- 0.4 got ulcers
  • Control group- 4 got ulcers
  • Effectiveness based on risk ratio (RR)

8
Conclusion
  • Topical agents actually increased ulcers in
    Houwing study
  • Topical agents vs. placebo was inconclusive
  • Dressings decreased ulcer occurance in Kalowes
    study
  • Dressings were effective in general
  • Studies were inconsistent with each other (ex
    follow up times)

9
The future
  • Trials should be bigger to show more meaningful
    results
  • More variables should be kept constant
  • Better technology could create more effective
    topical agents, dressings, or a combo of both.
