Clinician Accuracy in Identifying and Predicting Organ Dysfunction in Critically Ill Children

Area of Science:

• Pediatric critical care medicine
• Clinical diagnostics
• Patient outcomes

Background:

• Multiple organ dysfunction syndrome (MODS) is a significant cause of morbidity and mortality in critically ill children.
• Accurate identification and prediction of MODS are crucial for timely intervention and improved patient outcomes.
• Clinician accuracy in assessing organ dysfunction in the Pediatric Intensive Care Unit (PICU) requires further investigation.

Purpose of the Study:

• To evaluate the accuracy of PICU clinicians in identifying existing MODS.
• To assess the ability of clinicians to predict new or progressive MODS.
• To compare clinician accuracy across different provider types and explore factors influencing prediction accuracy.

Main Methods:

• Prospective cohort study conducted at a children's hospital PICU.
• Clinician assessments of organ dysfunction were compared against the Proulx criteria for MODS.
• Survey data collected from attending physicians, fellows, and residents/nurse practitioners on patient organ dysfunction and prediction confidence.

Main Results:

• Clinicians demonstrated approximately 80% accuracy in identifying existing MODS and predicting new/progressive MODS.
• The positive predictive value for new or progressive MODS was low at 22.1%, with weak likelihood ratios (3.0 positive, 0.7 negative).
• Accuracy did not significantly differ by clinician type (attending, fellow, resident/NP), and confidence showed a weak correlation with accuracy.

Conclusions:

• While PICU clinicians exhibit high overall accuracy in MODS identification, their predictive accuracy for new or progressive MODS is limited, primarily driven by correct negative predictions.
• The low positive predictive value suggests that clinician predictions of new or worsening MODS should be interpreted with caution.
• Further research may be needed to develop more robust tools for predicting MODS progression in critically ill children.
