Reliability and Validity of the Emergency Severity Index for Pediatric Triage

Objectives:  The Emergency Severity Index (ESI) triage algorithm is a five‐level triage acuity tool used by emergency department (ED) triage nurses to rate patients from Level 1 (most acute) to Level 5 (least acute). ESI has established reliability and validity in an all‐age population, but has not...

Zusammenfassung:Objectives:  The Emergency Severity Index (ESI) triage algorithm is a five‐level triage acuity tool used by emergency department (ED) triage nurses to rate patients from Level 1 (most acute) to Level 5 (least acute). ESI has established reliability and validity in an all‐age population, but has not been well studied for pediatric triage. This study assessed the reliability and validity of the ESI for pediatric triage at five sites. Methods:  Interrater reliability was measured with weighted kappa for 40 written pediatric case scenarios and 100 actual patient triages at each of five research sites (independently rated by both a triage nurse and a research nurse). Validity was evaluated with a sample of 200 patients per site. The ESI ratings were compared with outcomes, including hospital admission, resource consumption, and ED length of stay. Results:  Interrater reliability was 0.77 (95% confidence interval [CI] = 0.76 to 0.78) for the scenarios (n = 155 nurses) and 0.57 (95% CI = 0.52 to 0.62) for actual patients (n = 498 patients). Inconsistencies in triage were noted for the most acute and least acute patients, as well as those less than 1 year of age and those with medical (rather than trauma) chief complaints. For the validity cohort (n = 1,173 patients), outcomes differed by ESI level, including hospital admission, which went from 83% for Level 1 patients to 0% for Level 5 (chi‐square, p
