Abstract
Objective: The purpose of this study was to verify, through an integrative review, how the (Manchester Triage System (MTS) use specificity is described in the pediatric population. Methods: This is an integrative review carried out through searches in the SciELO, LILACS and Pubmed databases. The descriptors available were unrelated to the descriptors of health science (DECS): screening, emergency medical services, nursing, children, pediatrics. Results: After the search and analysis of the data considered eligible, the results were evidenced in the scientific expression in the regional bases (LILACS and SciELO); it is still observed that most of the sample of articles comes from the search in PUBMED. The use of the research method was predominantly observational and prospective, and the number of individuals studied ranged from 191 to 64,653. Overall, the Manchester Screening System (MTS) was not considered to have high specificity or sensitivity with regard to emergency care in the pediatric population. Final considerations: MTS presented important limitations in the studies analyzed in regard to care and classification in pediatric urgency and clinical conditions associated with infectious processes and other disorders, and greater reliability in emergency situations or requiring immediate care.
