Transport Risk Index of Physiologic Stability, version II (TRIPS-II): a simple and practical neonatal illness...

Area of Science:

• Neonatal Medicine
• Pediatric Critical Care
• Clinical Assessment Tools

Background:

• Assessing illness severity in neonatal intensive care units (NICUs) is crucial for patient management and benchmarking.
• Existing tools may not adequately capture the dynamic physiological status of critically ill infants upon admission.

Purpose of the Study:

• To derive and validate a practical clinical assessment tool for infant illness severity at NICU admission.
• To establish a reliable method for benchmarking infant illness severity in NICUs.

Main Methods:

• A prospective study of 17,075 infants across 15 NICUs (2006-2008).
• Logistic regression was used to develop the Transport Risk Index of Physiologic Stability, version II (TRIPS-II), based on four key physiological parameters.
• TRIPS-II was validated for predicting 7-day and total NICU mortality.

Main Results:

• TRIPS-II demonstrated strong discrimination for 7-day (ROC area, 0.90) and total NICU mortality (ROC area, 0.87).
• Changes in TRIPS-II scores at 12 and 24 hours correlated with mortality.
• The tool showed good calibration and improved prediction models when combined with gestational age and baseline risk variables.

Conclusions:

• The Transport Risk Index of Physiologic Stability, version II (TRIPS-II) is a validated tool for assessing infant illness severity.
• TRIPS-II can be used for benchmarking infant illness severity at admission and up to 24 hours post-admission.
