Objective. The development of PTSD after physical trauma is increasingly recognised as a concerning complication in more than one fifth of patients. Early identification of patients who are at higher risk of developing PTSD is imperative to ensure suitable interventions can be implemented. This is achieved by use of screening tools. The aim of this systematic review is to outline the tools which have been utilised and the efficacy of such screens, focusing on inpatient or EMR (electronic medical record) tools. Methods. The PRISMA outline was used to guide this review. A total of 8,148 articles were identified through database searches. This was narrowed down to a total of 154 for full text review. A total of 20 studies met criteria for inclusion. Results. PTSD prediction and screening in trauma patients was explored with a variety of tools in these studies. Self-report questionnaires showed a range of sensitivities from 50-90%, and EMR based tools showed sensitivities up to 84%. Risk prediction models were also developed such as TIPPS with key patient factors incorporated, and showed sensitivity of 81%. Conclusion.. Use of screening tools for identifying at risk trauma patients is an efficient use of resources. There are a multitude of screens which have been adapted in several trauma populations demonstrating good sensitivity/ specificity. For comprehensive PTSD screening in trauma patients, integrating both efficient EMR tools for initial screening and validated self-report questionnaires with robust follow up protocols offers a thorough approach to identifying and managing PTSD post-injury.
