Trajectories and Risk Factors for Altered Physical and Psychosocial Health-Related Quality of Life After Pediatric Community-Acquired Septic Shock

Abstract

Objectives: To evaluate the physical and psychosocial domains of health-related quality of life among children during the first year following community-acquired septic shock, and explore factors associated with poor physical and psychosocial health-related quality of life outcomes.

Design: Secondary analysis of the Life After Pediatric Sepsis Evaluation.

Setting: Twelve academic PICUs in the United States.

Patients: Children greater than or equal to 1 month and less than 18 years old who were perceived to be without severe developmental disability by their family caregiver at baseline and who survived hospitalization for community-acquired septic shock.

Interventions: Family caregivers completed the Pediatric Quality of Life Inventory for children 2-18 years old or the Pediatric Quality of Life Inventory Infant Scales for children less than 2 years old at baseline (reflecting preadmission status), day 7, and months 1, 3, 6, and 12 following PICU admission. Higher Pediatric Quality of Life Inventory Physical and Psychosocial Health Summary Scores indicate better health-related quality of life.

Measurements and main results: Of 204 children, 58 (28.2%) had a complex chronic comorbid condition. Children with complex chronic comorbid conditions had lower baseline physical health-related quality of life (62.7 ± 22.6 vs 84.1 ± 19.7; p < 0.001) and psychosocial health-related quality of life (68.4 ± 14.1 vs 81.2 ± 15.3; p < 0.001) than reference norms, whereas children without such conditions had baseline scores similar to reference norms. Children with complex chronic comorbid conditions recovered to their baseline health-related quality of life, whereas children without such conditions did not (physical health-related quality of life 75.3 ± 23.7 vs 83.2 ± 20.1; p = 0.008 and psychosocial health-related quality of life 74.5 ± 18.7 vs 80.5 ± 17.9; p = 0.006). Age less than 2 years was independently associated with higher month 12 physical health-related quality of life, and abnormal neurologic examination and neurologic injury suspected by a healthcare provider during the PICU course were independently associated with lower month 12 physical health-related quality of life. Treatment of increased intracranial pressure and medical device use at month 1 were independently associated with lower month 12 psychosocial health-related quality of life.

Conclusions: Physical and psychosocial health-related quality of life were reduced among children during the first year following community-acquired septic shock compared with reference norms, although many recovered to baseline. Risk factors for poor health-related quality of life included neurologic complications during the hospitalization and dependence on a medical device 1 month postadmission.

Reference group obtained in Varni et al (2003) (21). Chronic comorbid condition assessed according to the Pediatric Medical Complexity Algorithm (PMCA) and determined using ICD 9/10 diagnosis codes up to three years prior the ICU sepsis admission (30).
