Risk Factors for Positive Post-Traumatic Stress Disorder Screening and Associated Outcomes in Children Surviving Acute Respiratory Failure: A Secondary Analysis of the Randomized Evaluation of Sedation Titration for Respiratory Failure Clinical Trial.

Objectives: To identify risk factors and outcomes associated with a positive post-traumatic stress disorder (PTSD) screen following pediatric acute respiratory failure treated with invasive mechanical ventilation.
Design: Nonprespecified secondary analysis of a randomized clinical trial.
Setting: Thirty-one U.S. PICUs.
Patients: Children in the Randomized Evaluation of Sedation Titration for Respiratory Failure (RESTORE) trial (NCT00814099, ClinicalTrials.gov ) over 8 years old who completed PTSD screening 6 months after discharge.
Interventions: RESTORE sites were randomized to a targeted, nurse-directed sedation strategy versus usual care.
Measurements and Main Results: PTSD screening was completed by 102 subjects using the Child Post-Traumatic Stress Disorder Symptom Scale; a score of greater than or equal to 11 was considered screening positive for PTSD. Cognitive status was categorized using Pediatric Cerebral Performance Category; health-related quality of life (HRQL) was evaluated using child-reported Pediatric Quality of Life Inventory, Version 4.0. Thirty-one children (30%) screened positive for PTSD. Children with a positive screen endorsed symptoms in all categories: reexperiencing, avoidance, and hyperarousal. Most endorsed that symptoms interfered with schoolwork ( n = 18, 58%) and happiness ( n = 17, 55%). Screening positive was not associated with RESTORE treatment group. In a multivariable logistic model adjusting for age, sex, and treatment group, screening positive was independently associated with lower median income in the family's residential zip code (compared with income ≥ $80,000; income < $40,000 odds ratio [OR], 32.8; 95% CI, 2.3-458.1 and $40,000-$79,999 OR, 15.6; 95% CI, 1.3-182.8), renal dysfunction (OR 5.3, 95% CI 1.7-16.7), and clinically significant pain in the PICU (OR, 8.3; 95% CI, 1.9-35.7). Children with a positive screen experienced decline in cognitive function and impaired HRQL more frequently than children with a negative screen.
Conclusions: Screening positive for PTSD is common among children following acute respiratory failure and is associated with lower HRQL and decline in cognitive function. Routine PTSD screening may be warranted to optimize recovery.
