Insights
Tracking Pediatric Logistic Organ Dysfunction (PELOD) scores daily in critically ill children helps predict mortality. Specific measurement days offer optimal insights into disease progression.
Area of Science:
- Pediatric critical care medicine
- Clinical scoring systems
- Multiorgan dysfunction syndrome (MODS)
Background:
- Daily assessment of MODS is standard in adult critical care.
- The Pediatric Logistic Organ Dysfunction (PELOD) score evaluates critically ill children.
- This study aimed to assess PELOD score changes over time and identify optimal measurement days.
Purpose of the Study:
- To evaluate the clinical course of MODS in critically ill children using the PELOD score.
- To determine the optimal days for measuring PELOD scores to predict mortality.
- To analyze the relationship between PELOD score changes and PICU mortality.
Main Methods:
- Prospective study of 1806 children in seven PICUs.
- Daily PELOD scores were recorded and changes over time analyzed.
- Cox survival analyses were used to identify optimal measurement days.
Main Results:
- Overall PICU mortality was 6.4%.
- High initial PELOD scores (≥20) on day 1 significantly increased mortality risk (OR 40.7).
- A specific set of seven days (1, 2, 5, 8, 12, 16, 18) was identified as optimal for PELOD score measurement.
Conclusions:
- Worsening or static PELOD scores indicate poor prognosis in critically ill children.
- Using a seven-day measurement schedule for PELOD scores provides optimal information on MODS progression.
- This approach aids in predicting outcomes for critically ill children.
Background:
Daily evaluation of multiple organ dysfunction syndrome has been performed in critically ill adults. We evaluated the clinical course of multiple organ dysfunction over time in critically ill children using the Pediatric Logistic Organ Dysfunction (PELOD) score and determined the optimal days for measuring scores.
Methods:
We prospectively measured daily PELOD scores and calculated the change in scores over time for 1806 consecutive patients admitted to seven pediatric intensive care units (PICUs) between September 1998 and February 2000. To study the relationship between daily scores and mortality in the PICU, we evaluated changes in daily scores during the first four days; the mean rate of change in scores during the entire PICU stay between survivors and nonsurvivors; and Cox survival analyses using a change in PELOD score as a time-dependent covariate to determine the optimal days for measuring daily scores.
Results:
The overall mortality among the 1806 patients was 6.4%. A high PELOD score (>or=20 points) on day 1 was associated with an odds ratio (OR) for death of 40.7 (95% confidence interval [CI] 20.3-81.4); a medium score (10-19 points) on day 1 was associated with an OR for death of 4.2 (95% CI 2.0-8.7). Mortality was 50% when a high score on day 1 increased on day 2. The course of daily PELOD scores differed between survivors and nonsurvivors. A set of seven days (days 1, 2, 5, 8, 12, 16 and 18) was identified as the optimal period for measurement of daily PELOD scores.
Interpretation:
PELOD scores indicating a worsening condition or no improvement over time were indicators of a poor prognosis in the PICU. A set of seven days for measurement of the PELOD score during the PICU stay provided optimal information on the progression of multiple-organ dysfunction syndrome in critically ill children.
