Insights
No pediatric mass-casualty incident (MCI) triage system is consistently accurate. A new secondary triage system shows promise, but further research is needed for reliable pediatric MCI patient care.
Area of Science:
- Emergency Medicine
- Pediatric Critical Care
- Disaster Management
Background:
- Pediatric mass-casualty incident (MCI) triage lacks a universally accepted system.
- Current systems may exhibit poor reliability and agreement among providers.
- Existing methods risk underestimating or missing critically ill pediatric patients.
Purpose of the Study:
- To conduct a scoping review to identify the most accurate triage system for pediatric patients in mass-casualty incidents (MCIs).
Main Methods:
- Searched multiple databases including MEDLINE, Embase, CINAHL, Cochrane CENTRAL, Scopus, Global Health, Global Health Archive, and Global Index Medicus.
- Included studies focused on the accuracy of single systems, comparisons of primary triage systems, and comparisons of secondary triage systems.
- Grey literature was also searched to ensure comprehensive data collection.
Main Results:
- Out of 996 identified studies, 18 were included in the review.
- Triage systems demonstrated poor inter-rater reliability, low provider agreement, and inadequate external validation.
- While no single primary pediatric MCI triage algorithm was found to be definitively most accurate, one newly developed secondary triage system outperformed its comparison.
- 11 studies compared different pediatric MCI triage algorithms, but a superior primary algorithm was not identified.
Conclusions:
- No primary triage algorithm currently meets the accuracy requirements for the pediatric population in mass-casualty incidents.
- A specific secondary triage algorithm demonstrated superiority, suggesting potential for improved pediatric patient management in MCIs.
- Further research and validation are necessary to establish reliable triage protocols for pediatric mass-casualty events.
Objective:
For the pediatric population, there is no consensus on which triage system to use for mass-casualty incidents (MCI). A scoping review was conducted to identify the most accurate triage system for pediatric patients in MCIs.
Methods:
MEDLINE (NLM, Bethesda, MA, USA), Embase (Elsevier Inc., Amsterdam, Netherlands), CINAHL (EBSCO Information Services, Ipswitch, MA, USA), and The Cochrane CENTRAL Register of Controlled Trials (John Wiley & Sons, Hoboken, NJ, USA), as well as Scopus (Elsevier Inc., Amsterdam, Netherlands), Global Health (Centre for Agriculture and Bioscience International, Wallingford, UK), Global Health Archive (Centre for Agriculture and Bioscience International, Wallingford, UK), and Global Index Medicus (World Health Organization, Geneva, Switzerland) were searched for relevant studies that were divided into 3 categories: accuracy of a single system, comparison of 2 or more primary triage system and comparison of secondary triage systems. Grey literature was also searched.
Results:
996 studies were identified from which 18 studies were included. Systems studied were found to have poor inter-rater reliability, had a low level of agreement between providers, had missed critically ill patients or were not externally validated. 11 studies compared pediatric MCI triage algorithms using different strategies and the most accurate algorithm was not identified. A recently developed secondary triage system, specifically for pediatric patients, was found to perform better than the comparison triage system.
Conclusion:
Although some algorithms performed better than others, no primary triage algorithm was accurate enough for the pediatric population. However, only 1 secondary triage algorithm was found to be superior to the others.
