A cluster randomized controlled trial to determine the efficacy of Trauma Risk Management (TRiM) in a military population

Abstract: Trauma Risk Management is a peer-support program that aims to promote help-seeking in the aftermath oftraumatic events. Prior to its implementation, the British military conducted a randomized controlled trialof Trauma Risk Management against standard care in 12 warships; 6 were randomized to use Trauma RiskManagement after collecting baseline measurements. Follow up after 12–18 months found no significant changein psychological health or stigma scores in either group; however, the studied vessels only encountered low numbersof critical incidents. Additionally, measurements of organizational functioning were modestly better in the TraumaRisk Management ships. The authors conclude that within organizations using Trauma Risk Management maybe beneficial and may, in time, lead to a valuable cultural shift.
