Pediatric Transport–Specific Illness Severity Scores Predict Clinical Deterioration of Transported Patients

Abstract

Objective 

The Transport Risk Assessment in Pediatrics (TRAP) and Transport Pediatric Early Warning Scores (T-PEWS) are transport-specific pediatric illness severity scores that are adjunct assessment tools for determining disposition of transported patients. We hypothesized that these scores would predict the risk of clinical deterioration in transported patients admitted to general pediatric wards.

Methods 

Activation of a rapid response team (RRT) in the first 24 hours of admission was used as a marker of deterioration. All pediatric transports between March 2017 and February 2020 admitted via critical care transport were included. Transports to the emergency department (ED) were excluded. This retrospective chart review evaluated TRAP and T-PEWS scores at 3 points: (1) arrival of transport team at referring hospital, (2) admission to the children’s hospital, and (3) RRT activation, if occurring within 24 hours of admission.

Results 

There were 1137 team transports during this period. Three hundred ninety-nine patients transported to the ED were excluded, leaving 738 included patients; 405 (55%) admitted to the general wards and 333 (45%) admitted to the pediatric intensive care unit. Twenty-five patients admitted to the wards (6%) had an RRT activation within 24 hours of admission. Statistical analysis used 2-sample t tests. There was a statistically significant difference in scores for ward admissions between those who had RRT activation and those who did not.

Conclusions 

Both TRAP and T-PEWS can be used to predict the risk of clinical deterioration in transported patients admitted to general wards. These scores may assist in assessing which patients admitted to the wards need closer observation.
