Introduction: Exsanguination is the most preventable cause of death. Paradigms such as STOP THE BLEED recognize increased responsibility among the less experienced with Wound Packing (WP) being a critical skill. As even trained providers may perform poorly, we compared Video-modelling (VM), a form of behavioural modelling involving video demonstration prior to intervention against remote telementoring (RTM) involving remote real-time expert-guidance.
Methods: Search and Rescue (SAR-Techs), trained in WP were asked to pack a wound on a standardized simulator randomized to RMT, VM, or control.
Results: 24 SAR-Techs (median age 37, median 16.5 years experience) participated. Controls were consistently faster than RTM (p = 0.005) and VM (p = 0.000), with no difference between RTM and VM. However, 50% (n = 4) Controls failed to pack properly, compared to 100% success in both VM and RTM, despite all SAR-Techs feeling the task was "easy".
Discussion: Performance of a life-saving technique was improved through either VM or RTM, suggesting that both techniques are beneficial and complementary to each other. Further work should be extended to law enforcement/lay public to examine logistical challenges.
