Prevalence of Posttraumatic Stress Disorder among Road Traffic Accident Survivors: A PRISMA-Compliant Meta-Analysis

This article reports on a meta-analysis undertaken to determine the prevalence of posttraumatic stress disorder (PTSD) among survivors of crashes. The authors searched electronic databases of PubMed, Embase, Web of Science, PsycARTICLES, PsycINFO, and CINAHL to identify appropriate studies. Each study and data extraction was analyzed independently by two investigators. Heterogeneity among studies was evaluated using the Cochran Q test and quantified using the I2 statistic. The possibility of publication bias was assessed using Egger linear test. The authors identified 15 studies that included 6,804 road traffic crash survivors. Of those survivors, 1,489 were diagnosed with PTSD. Thus, the pooled prevalence of PTSD among RTA survivors was 22.25% (95% confidence interval: 16.71%–28.33%). The authors note that there was a high degree of heterogeneity across studies, with reported PTSD prevalence ranging from 6.3% to 58.3%. This heterogeneity was attributed to the instrument used to assess PTSD, country, race, gender, and education level.
