Abstract
BACKGROUND: Post-traumatic stress disorder (PTSD) is one of the most commonly reported mental health consequences, followed by disasters and traumatic events, either natural or man-made. At present, there are no unified results for the prevalence rate of PTSD in patients suffering from acute trauma and related influencing factors. Therefore, the purpose of this study is to systematically evaluate the existing literatures, thus obtaining a comprehensive estimation of the combined prevalence rate of PTSD and related factors in trauma patients, so as to provide evidence support for clinical disease prediction models and intervention strategies. METHODS: Published articles will be retrieved from PubMed, Embase, Cochrane Library, Web of Science, China Biology Medicine Database, China National Knowledge Infrastructure, China Science and Technology Journal Database, and Wanfang Database. Research reports will be searched in March 2021. STATA 14.0 software will be applied for data analysis. Mantel-Haenszel fixed effect model or DerSimonian-Laird random effect model will be selected to estimate the pooled prevalence of PTSD in patients with acute trauma and associated factors. RESULTS: We will disseminate the findings of this systematic review and meta-analysis via publications in peer-reviewed journals. CONCLUSIONS: The results of this analysis can be used to establish a risk prediction model of PTSD in patients experiencing acute trauma, so as to provide intervention strategies.
