Life After Pediatric Sepsis Evaluation

Overview

Sepsis represents the leading cause of childhood mortality worldwide. However, as distinct from adult medicine, there exists a large knowledge gap regarding long term health related quality of life (HRQL) and functional status (FS) following pediatric sepsis. This lack of sepsis outcomes data is critical because failure to identify children at risk for sepsis associated HRQL/FS deterioration may delay delivery of crucial rehabilitation medicine efforts to facilitate recovery. Moreover, failure to identify mechanisms of sepsis associated HRQL/FS deterioration may impede development of novel, effective interventions for these children. For the first time the LAPSE investigation will quantify deterioration of HRQL/FS among children surviving sepsis. We will measure the incidence, magnitude and duration of HRQL/FS alterations associated with pediatric septic shock, and examine clinical, sociodemographic, and parent/family factors potentially associated with such adverse outcomes. Because sepsis affects a heterogeneous group of children, long term morbidity associated with sepsis likely depends on premorbid health status and parent, family and home characteristics, as well as children's clinical course during sepsis critical illness. Mechanisms underlying adverse sepsis outcomes among children are poorly understood at this time. Clinically multiple organ dysfunction syndrome (MODS) has been clearly linked to sepsis mortality. To begin to understand pathophysiology underlying pediatric sepsis morbidity, this investigation will seek to identify evidence for association of HRQL/FS alterations following sepsis with intensity and duration of sepsis mediated organ dysfunction as well as with pre-existing comorbidities and parent, family, and home characteristics. The long-term goal of this research program is to timely identify children at high risk of sepsis mediated HRQL/FS deterioration and ultimately to design effective interventions to minimize such risk. The primary objectives of this investigation are to comprehensively characterize HRQL/FS trajectory and to critically examine the potential role of sepsis mediated organ dysfunction as well as pre-existing comorbidities and parent, family, and home characteristics as risk factors for the adverse outcomes. The central hypothesis is that intensity of sepsis organ dysfunction will predict magnitude of HRQL/FS deterioration. We also hypothesize that the trajectory towards baseline HRQL/FS following the sepsis event will also depend on pre-existing co-morbidities and parent, family, and home, and characteristics. Knowledge of these potential mechanisms will ultimately facilitate development of targeted interventions to maximize HRQL/FS among children surviving sepsis.

In-hospital pediatric sepsis mortality has decreased substantially, but long-term mortality and morbidity among children initially surviving sepsis, is unknown. Accordingly, the Life After Pediatric Sepsis Evaluation investigation was conducted to describe the trajectory of mortality and health-related quality of life morbidity and critical illness factors associated with these outcomes for children encountering community-acquired septic shock. Design: Prospective, cohort-outcome study, conducted 2013-2017. Setting: Twelve academic pediatric intensive care units (PICUs) in the United States. Patients: Critically ill children, 1 month to 18 years, with community-acquired septic shock requiring vasoactive-inotropic support. Interventions: Demographic, infection, and illness severity data were collected at PICU admission. Organ dysfunction and resource utilization data were collected during PICU stay. Serial parent proxy-report health-related quality of life assessments were obtained at baseline, 7 days, and 1, 3, 6, and 12 months following PICU admission utilizing the Pediatric Quality of Life Inventory or Stein-Jessop Functional Status Scale.
