ObjectiveWe investigated the diagnostic value of shock index, pediatric age-adjusted (SIPA) in predicting Emergency Severity Index level 3 patients' outcomes. Secondary objectives included exploring the impact of fever and participant variables on SIPA's predictive ability.MethodsA retrospective chart review identified children aged 1 to 15 years triaged as a level 3 in the emergency department between January 2018 and December 2021. Shock index, pediatric age-adjusted thresholds based on age, 1 to 6 years (>1.2), 7 to 12 years (>1.0), and 13 to 17 years (>0.9), were used. We assessed elevated SIPA and SIPA corrected for fever to evaluate associations with outcomes and interventions.ResultsOur findings, involving 192 patients, revealed that elevated SIPA demonstrated enhanced discrimination relative to nonelevated SIPA. Patients with elevated SIPA had more average interventions: 1.14 versus 0.74, P < 0.016; average interventions using SIPA corrected for fever: 1.14 versus 0.77, P < 0.006; average interventions controlling for race and sex: 1.15 versus 0.71, P < 0.001; hospital admission: 64.4% versus 42.9%, P = 0.004; hospital length of stay (LOS): 3.06 days (SE, 0.42) versus 1.46 days (SE, 0.23); hospital LOS using SIPA corrected for fever: 2.75 days (SE, 0.44) versus 1.72 days (SE, 0.24); ventilatory support: 16.44% versus 3.36%, P < 0.002; fluid bolus: 28.77% versus 14.29%, P < 0.015; intravenous medications (antibiotics, antiepileptics, immune globulin, albumin): 45.21% versus 30.25%, P < 0.036. There was no difference between other interventions, pediatric intensive care admission, and LOS between the 2 groups. Importantly, SIPA was unaffected by fever, race, or sex.ConclusionsShock index, pediatric age-adjusted identifies level 3 Emergency Severity Index pediatric patients more likely to require hospital admission, longer LOS, and a lifesaving intervention especially ventilatory support, intravenous fluids, or specific intravenous medications. Shock index, pediatric age-adjusted's predictive ability remained unaffected by fever, race, or sex, making it a valuable tool in preventing mistriage and justifying inclusion in the Emergency Severity Index danger zone vitals criteria for up-triage.Copyright © 2024 Wolters Kluwer Health, Inc.
