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

TLDR

Trauma Risk Management is a peer‑support program designed to encourage help‑seeking after traumatic events. The study randomized six of twelve warships to receive Trauma Risk Management after baseline assessment, comparing it to standard care. The trial found no significant improvement in psychological health or stigma, but showed modest gains in organizational functioning, suggesting potential long‑term benefits.

Abstract

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