Eric Goralnick, M.D., and his colleagues conducted a trail involving 465 laypersons to determine the effectiveness of in-person training methods. Laypeople were separated into 4 different groups to assess correct tourniquet application that included the following groups:
Researchers concluded that the group that took part in a bleeding control course had superior outcomes for laypeople using proper bleeding control techniques and tools such as applying a tourniquet (See Chart Below).
Laypeople Groups: |
TQ Application Success |
Audio Kits |
23% |
Flashcards |
19.6% |
Bleeding Control Course |
88% |
Control |
16% |
Furthermore, follow-up assessments at 3 and 9 months showed that 54.5% of the 303 laypeople were still able to apply a tourniquet correctly.
Other interesting conclusions reached were that age was a factor in successful tourniquet application. Adults aged 18 to 35 years old and 35 to 55 years old were found to be the most effective with tourniquet application. Adults aged >55 had a lower success rate with tourniquet application.
