Validation of the PELOD score for multiple organ dysfunction in children

Area of Science:

• Pediatric critical care medicine
• Clinical scoring systems
• Epidemiology of pediatric critical illness

Background:

• Multiple organ dysfunction syndrome (MODS) is a common and serious complication in critically ill children.
• Early identification and risk stratification are crucial for improving outcomes in pediatric intensive care.
• The Pediatric Index of Mortality (PELOD) score is a tool used to assess the severity of illness in children.

Purpose of the Study:

• To prospectively evaluate the utility of the PELOD score in identifying children with multiple organ dysfunction at admission.
• To assess the impact of the PELOD score on predicting mortality in a pediatric intensive care unit (PICU) in North India.
• To analyze the prevalence of severe sepsis/septic shock as a primary admission diagnosis.

Main Methods:

• Prospective study conducted over 13 months in a tertiary care hospital's PICU in North India.
• Data collection using a predesigned sheet for 209 admitted patients.
• Calculation of the PELOD score for each patient upon admission.

Main Results:

• Ninety-one percent of admitted children presented with multiple organ dysfunction.
• Severe sepsis/septic shock was the primary indication for admission in 37.2% of cases.
• The PELOD score demonstrated a significant predictive value for mortality, with an area under the curve of 0.80.

Conclusions:

• The PELOD score is a valuable tool for identifying multiple organ dysfunction in critically ill children at admission.
• The PELOD score effectively predicts mortality in the PICU setting.
• High prevalence of multiple organ dysfunction and severe sepsis/septic shock underscores the critical nature of PICU admissions.
