Assessment of Patient Health-Related Quality of Life and Functional Outcomes in Pediatric Acute Respiratory Distress Syndrome*

OBJECTIVES: To describe health-related quality of life (HRQL) and functional outcomes in pediatric acute respiratory distress syndrome (ARDS) and to determine risk factors associated with poor outcome defined as death or severe reduction in HRQL at 28 days or ICU discharge. DESIGN: Prospective multisite cohort-outcome study conducted between 2019 and 2020. SETTING: Eight academic PICUs in the United States. PATIENTS: Children with ARDS based on standard criteria. INTERVENTIONS: Patient characteristics and illness severity were collected during PICU admission. Parent proxy-report measurements were obtained at baseline, day 28/ICU discharge, month 3, and month 9, utilizing Pediatric Quality of Life Inventory and Functional Status Scale (FSS). A composite outcome evaluated using univariate and multivariate analysis was death or severe reduction in HRQL (>25% reduction in the Pediatric Quality of Life Inventory at day 28/ICU discharge. MEASUREMENTS AND MAIN RESULTS: This study enrolled 122 patients with a median age of 3 years (interquartile range, 1-12 yr). Common etiologies of ARDS included pneumonia (n = 63; 52%) and sepsis (n = 27; 22%). At day 28/ICU discharge, half (50/95; 53%) of surviving patients with follow-up data reported a greater than 10% decrease in HRQL from baseline, and approximately one-third of participants (n = 19/61; 31%) reported a greater than 10% decrease in HRQL at 9 months. Trends in FSS were similar. Of 104 patients with data, 47 patients (45%) died or reported a severe decrease of greater than 25% in HRQL at day 28/ICU discharge. Older age was associated with an increased risk of death or severe reduction in HRQL (odds ratio, 1.08; CI, 1.01-1.16). CONCLUSIONS: Children with ARDS are at risk for deterioration in HRQL and FSS that persists up to 9 months after ARDS. Almost half of children with ARDS experience a poor outcome including death or severe reduction in HRQL at day 28/ICU discharge.

Automated summary

This study explores the health-related quality of life (HRQL) and functional outcomes in pediatric acute respiratory distress syndrome (ARDS). The findings indicate that children with ARDS are at risk for deterioration in HRQL and functional status that persists up to 9 months after ARDS. Approximately half of the children experience a poor outcome, including death or severe reduction in HRQL at day 28/ICU discharge. Older age is associated with an increased risk of poor outcome or severe reduction in HRQL.
