Prevalence of traumatic psychological stress reactions in children and parents following paediatric surgery: a systematic review and meta-analysis

Abstract

Background Children undergoing surgery, and their parents, are at risk of developing post-traumatic stress reactions. We systematically reviewed the literature to understand the prevalence of this issue, as well as potential risk factors. Methods We conducted a systematic review and meta-analysis, using PubMed, PsycInfo, Web of Science and Google Scholar, with searches conducted in February 2021. Papers were included if they measured post-traumatic stress in children and/or parents following paediatric surgery, and were excluded if they did not use a validated measure of post-traumatic stress. Data was extracted from published reports. Findings Our search yielded a total of 1,672 papers, of which 16 of met our inclusion criteria. In meta-analysis, pooled studies of children estimated an overall prevalence of 16% meeting criteria for post-traumatic stress disorder post-surgery (N= 187, 95% CI : 5-31%, I2 = 80%). After pooling studies of parents, overall prevalence was estimated at 23% (N= 1444, 95% CI 16-31%, I2 = 91%). Risk factors reported within studies included length of stay, level of social support and parental mental health. Interpretation There is consistent evidence of traumatic stress following surgery in childhood which warrants further investigation. Those delivering surgical care to children would benefit from a raised awareness of the potential for post-traumatic stress in their patients and their families, including offering screening and support.
