How is relapse related to PTSD?

Studies suggest there are high rates of relapse within a year of discharge from psychiatric institutions, with most being within the first three months. Sociodemographic and hospitalisation characteristics may influence the risk of relapse. Identifying the predictors of readmission can inform health policies and improve interventions to mitigate the cost and burden to systems, patients, and families.

What is the evidence for relapse in people with PTSD?

Overall, moderate quality evidence found no significant differences in the rates of psychiatric readmission between people with PTSD and people with other mental disorders.

There was an increased risk of readmission in people with a prior psychiatric hospitalisation compared to no hospitalisation history (medium-sized effect), longer versus shorter length of hospital stay (small effect), and being discharged to residential rather than another treatment facility (small effect). There was a trend (but non-significant) effect for reduced rates of readmission when a parent was the primary caregiver compared to another primary caregiver in children and adolescents with PTSD.

There were no significant differences in rates of readmission according to patient age, gender, ethnicity, having a familial history of a psychiatric disorder, or having a history of childhood abuse.
