Posttraumatic stress symptoms and interpersonal processes in burn survivors and their partners

The prevalence of posttraumatic stress disorder symptomatology and diagnosis in burn survivors: a systematic review and meta-analysis

Great disparity is observed among studies investigating the prevalence of PTSD after burns. This systematic review and meta-analysis aimed to explore the pooled prevalence of PTSD in adult burn survivors over the first two years post-burn. Five electronic databases were searched for observational studies assessing the prevalence of PTSD symptoms after burns. Meta-analysis was performed using an auto-correlation and hierarchical effects model to estimate the course of PTSD prevalence rates over time and to establish point-prevalences. The effect of different moderators over time was tested with meta-regression. Thirty-two studies were included in the meta-analysis. The overall pooled prevalence of PTSD was 20.5% (95% CI 16.4-24.6) and the prevalence significantly decreased by about 0.37% per month post-burn over time. Questionnaire-based studies, and studies published from 2000 onwards, were more likely to show a decrease in PTSD prevalence over time compared to diagnostic studies and studies before 2000. A qualitative comparison revealed that inter-continental differences are likely to be complex and multi-factorial. PTSD affects about one in five burn survivors, with moderately decreasing rates from six months post-burn onwards. Early screening and identification of burn survivors who require specialist psychological care are vital for burns services.
