Abstract Objective To describe the association of maternal and neonatal characteristics with the adherence status to the in-hospital stages of the Kangaroo-Mother Care Method - KMC (full, partial, and no-adherence). Methods Retrospective cohort study including infants < 2500 g admitted to a reference maternity hospital for the KMC in Rio de Janeiro from January to December 2018. Maternal and neonatal characteristics were distributed according to the adherence status to the KMC in-hospital stages. In the first stage, KMC is performed in Neonatal Intensive Care Unit and Conventional Neonatal Intermediate Care Unit. The second stage is completed in Kangaroo Neonatal Intermediate Care Unit. Multinomial multiple regression was performed with KMC adherence as a three-category dependent variable and maternal and neonatal characteristics as independent variables. Results Of 166 dyads, 102 (61.5%) participated in two stages. Those who did not participate in any stage (n = 52; 31.3%) had a lower level of education, a higher frequency of adverse conditions, and were more often single mothers; mothers who participated only in the first stage (n = 12; 7,2%) had more premature and sick infants. Conditions associated with adherence to the two stages compared to no adherence were: high school education (OR = 2.34; 95% CI = 1.08-5.07), presence of a partner (OR = 3.82; 95% CI = 1.7-8.61), no adverse conditions (OR = 3.54; 95% CI = 1.59-7.89) and no neonatal resuscitation (OR = 2.73; 95% CI = 1.22-6.1). Conclusions The study identified maternal and neonatal conditions associated with adherence status to the KMC. The results suggest opportunities to improve adherence.

Abstract Objective: To evaluate the validity of the computerized version of the pediatric triage system CLARIPED. Methods: Prospective, observational study in a tertiary emergency department (ED) from Jan-2018 to Jan-2019. A convenience sample of patients aged 0-18 years who had computerized triage and outcome variables registered. Construct validity was assessed through the association between urgency levels and patient outcomes. Sensitivity, specificity, positive and negative predictive values (PPVand NPV), undertriage, and overtriage rates were assessed. Results: 19,122 of 38,321 visits were analyzed. The urgency levels were: RED (emergency) 0.02%, ORANGE (high urgency) 3.21%, YELLOW (urgency) 35.69%, GREEN (low urgency) 58.46%, and BLUE (no urgency) 2.62%. The following outcomes increased according to the increase in the level of urgency: hospital admission (0.4%, 0.6%, 3.1%, 11.9% and 25%), stay in the ED observation room (2.8%, 4.7%, 15.9%, 40.4%, 50%), ≥ 2 diagnostic or therapeutic resources (7.8%, 16.5%, 33.7%, 60.6%, 75%), and ED length of stay in minutes (18, 24, 67,120, 260). The odds of using ≥ 2 resources or being hospitalized were significantly greater in the most urgent patients (Red, Orange, and Yellow) compared to the least urgent (Green and Blue): OR 7.88 (95%CI: 5.35-11.6) and OR 2.85 (95%CI: 2.63-3.09), respectively. The sensitivity to identify urgency was 0.82 (95%CI: 0.77-0.85); specificity, 0.62 (95%CI: 0.61-0.6; NPV, 0.99 (95%CI: 0.99-1.00); overtriage rate, 4.28% and undertriage, 18.41%. Conclusion: The computerized version of CLARIPED is a valid and safe pediatric triage system, with a significant correlation with clinical outcomes, good sensitivity, and low undertriage rate.

Abstract: En | Text: En | PDF: En

Abstract Objectives: To describe the concept of toxic stress, present the basics of epigenetics and discuss their relationship with child development. Data source: Narrative literature review through a search in the SciELO, Lilacs, Medline databases using the terms Adverse Childhood Experience OR Early Life Stress, Epigenomic OR Epigenetic, Child Development OR Infant Development. Data synthesis: Continuing stress response, known as toxic stress, can occur when a child experiences intense, frequent, and/or prolonged adversity–such as physical or emotional abuse, chronic neglect, for example–without adequate adult support. This toxic stress can have harmful effects on learning, behavior, and health throughout life. Epigenetics, an emerging scientific research area, shows how environmental influences affect gene expressions and explains how early experiences can impact throughout life. Conclusions: Toxic stress causes changes in the human body response systems that can be explained in part by epigenetic changes, which can be temporary or long-lasting. Pediatricians must be aware of these mechanisms and their consequences, seeking to prevent them and thus promote the health, well-being, and quality of life of children, contributing to their full development.

Abstract Objectives To study the impact of the implementation of the Pediatric Surviving Sepsis Campaign protocol on early recognition of sepsis, 1 -h treatment bundle and mortality. Methods Retrospective, single-center study, before and after the implementation of the sepsis protocol. Outcomes: sepsis recognition, compliance with the 1 -h bundle (fluid resuscitation, blood culture, antibiotics), time interval to fluid resuscitation and antibiotics administration, and mortality. Patients with febrile neutropenia were excluded. The comparisons between the periods were performed using non-parametric tests and odds ratios or relative risk were calculated. Results We studied 84 patients before and 103 after the protocol implementation. There was an increase in sepsis recognition (OR 21.5 [95% CI: 10.1-45.7]), in the compliance with the 1 -h bundle as a whole (62% x 0%), and with its three components: fluid resuscitation (OR 31.1 [95% CI: 3.9−247.2]), blood culture (OR 15.9 [95% CI: 3.9−65.2]), and antibiotics (OR 35.6 [95% CI: 8.9−143.2]). Significant reduction between sepsis recognition to fluid resuscitation (152min × 12min, p < 0.001) and to antibiotics administration (137min × 30min) also occurred. The risk of death before protocol implementation was four times greater (RR 4.1 [95% CI: 1.2-14.4]), and the absolute death risk reduction was 9%. Conclusion Even if we considered the low precision of some estimates, the lower limits of the Confidence Intervals show that the implementation of the Pediatric Surviving Sepsis Campaign guidelines alongside a qualitive assurance initiative has led to improvements in sepsis recognition, compliance with the 1 -h treatment bundle, reduction in the time interval to fluid resuscitation and antibiotics, and reduction in sepsis mortality.

Abstract Objective To describe the clinical, laboratory, and radiological characteristics, as well as the outcomes of children with MIS-C. Method Multicenter, prospective cohort study, conducted in 17 pediatric intensive care units in five states in Brazil, from March to July 2020. Patients from 1 month to 19 years who met the MIS-C diagnostic criteria were included consecutively. Results Fifty-six patients were included, with the following conditions: Kawasaki-like disease (n = 26), incomplete Kawasaki disease (n = 16), acute cardiac dysfunction (n = 10), toxic shock syndrome (n = 3), and macrophage activation syndrome (n = 1). Median age was 6.2 years (IQR 2.4−10.3), 70% were boys, 59% were non-whites, 20% had comorbidities, 48% reported a contact with COVID-19 cases, and 55% had a recent SARS-CoV-2 infection confirmed by RT-PCR and/or serology. Gastrointestinal symptoms were present in 71%, shock symptoms in 59%, and severe respiratory symptoms in less than 20%. -Dimer was increased in 80% and cardiac dysfunction markers in more than 75%. Treatment included immunoglobulin (89%); corticosteroids, antibiotics, and enoxaparin in about 50%; and oseltamivir and antifungal therapy in less than 10%. Only 11% needed invasive mechanical ventilation, with a median duration of five days (IQR 5–6.5). The median length of PICU stay was six days (IQR 5–11), and one death occurred (1.8%). Conclusions Most characteristics of the present MIS-C patients were similar to that of other cohorts. The present results may contribute to a broader understanding of SARS-CoV-2 infection in children and its short-term consequences. Long-term multidisciplinary follow-up is needed, since it is not known whether these patients will have chronic cardiac impairment or other sequelae.

RESUMO Objetivo: Apresentar as atuais evidências sobre as características clínicas e laboratoriais da infecção pelo coronavírus da síndrome respiratória aguda grave 2 (SARS-CoV-2) durante a infância e a adolescência. Fonte de dados: Revisão narrativa realizada nas bases de dados Medical Literature Analysis and Retrieval System Online (MEDLINE/PubMed), Literatura Latino-Americana e do Caribe em Ciências da Saúde na Biblioteca Virtual em Saúde (LILACS/BVS), Scopus, Web of Science, Cochrane Library, portal da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), Scientific Electronic Library Online (SciELO), ScienceDirect e Cumulative Index to Nursing and Allied Health Literature (CINAHL), com o uso dos termos SARS-CoV-2, COVID-19 e novo coronavírus e criança, recém-nascido e adolescente. Síntese dos dados: Diferentemente dos adultos, as crianças infectadas pelo SARS-CoV-2 apresentam formas clínicas leves ou assintomáticas na maior parte dos casos. As crianças sintomáticas apresentam predominantemente febre baixa e tosse, com alguns sintomas gastrointestinais associados. Casos graves são a minoria e ocorrem especialmente abaixo de um ano de idade. A detecção de partículas virais em fezes parece ser mais persistente em crianças, podendo servir como ferramenta diagnóstica e de controle do tempo de quarentena. Diferentemente dos adultos, as crianças podem apresentar respostas inflamatórias distintas, como tem ocorrido nos novos casos de síndrome de Kawasaki-like associada à infecção pelo SARS-CoV-2. Conclusões: Crianças, na sua maioria, apresentam quadros assintomáticos ou leves, com predomínio de febre, tosse e sintomas gastrointestinais. Novos relatos de diferentes reações sistêmicas inflamatórias em crianças têm sido notados, com manifestações clínicas distintas daquelas tipicamente observadas em adultos.

ABSTRACT Objective: To present the current evidence on clinical and laboratory characteristics of infection by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during childhood and adolescence. Data source: This is a narrative review conducted in the databases: Medical Literature Analysis and Retrieval System Online (MEDLINE/PubMed), Latin American and Caribbean Health Sciences Literature in the Virtual Health Library (LILACS/VHL), Scopus, Web of Science, Cochrane Library, portal of the Coordination for the Improvement of Higher Education Personnel (Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES), Scientific Electronic Library Online (SciELO), ScienceDirect, and Cumulative Index to Nursing and Allied Health Literature (CINAHL). The terms used were SARS-CoV-2, COVID-19, novel coronavirus, child, newborn, and adolescent. Data synthesis: Unlike adults, most children infected by SARS-CoV-2 have mild or asymptomatic clinical presentations. Symptomatic children mainly have low fever and cough, with some associated gastrointestinal symptoms. Severe cases are rare and occur especially in infants under one year of age. Detection of viral particles in feces seems to be more persistent in children and can be used as a tool for diagnosis and control of the quarantine period. Different from adults, children can present distinct inflammatory responses, as has happened in new cases of Kawasaki-like syndrome associated with SARS-CoV-2 infection. Conclusions: Most children have asymptomatic or mild presentations, with a prevalence of fever, cough, and gastrointestinal symptoms. New cases with different systemic inflammatory reactions in children have been reported, with clinical manifestations distinct from those typically found in adults.

Resumo Objetivo: Descrever as características clínicas de crianças e adolescentes internados em unidade de terapia intensiva com COVID-19 confirmada. Método: Estudo prospectivo, multicêntrico, observacional, em 19 unidades de terapia intensiva pediátrica. Foram incluídos pacientes entre um mês e 19 anos, admitidos consecutivamente (março a maio de 2020). As características demográficas, clínico-epidemiológicas, o tratamento e os resultados foram coletados. Os subgrupos foram comparados de acordo com as comorbidades, idade < 1 ano e necessidade de ventilação mecânica invasiva. Um modelo de regressão logística multivariável foi utilizado para preditores de gravidade. Resultados: Setenta e nove pacientes foram incluídos (10 com síndrome inflamatória multi-ssistêmica). Mediana de idade, quatro anos; 54% eram do sexo masculino (síndrome inflamatória multissistêmica, 80%); 41% tinham comorbidades (síndrome inflamatória multissistêmica, 20%). Febre (76%), tosse (51%) e taquipneia (50%) foram comuns nos dois grupos. Sintomas graves egastrointestinais e marcadores inflamatórios mais elevados foram mais frequentes na presença de síndrome inflamatória multissistêmica. Infiltrados intersticiais pulmonares foram comuns em ambos os grupos, mas o derrame pleural foi mais prevalente no grupo com síndrome inflamatória multissistêmica (43% vs. 14%). A ventilação mecânica invasiva foi utilizada em 18% (mediana 7,5 dias); antibióticos, oseltamivir e corticosteroides foram utilizados em 76%, 43% e 23%, respectivamente, mas não a hidroxicloroquina. A mediana do tempo de permanência na unidade de terapia intensiva pediátrica foi de 5 dias; duas mortes ocorreram (3%) no grupo não- síndrome inflamatória multissistêmica. Os pacientes com comorbidades eram mais velhos, e as comorbidades foram independentemente associadas à necessidade de ventilação mecânica invasiva(OR 5,5; IC95%, 1,43-21,12; P 0,01). Conclusões: Nas unidades de terapia intensiva pediátrica brasileiras, a COVID-19 apresentou baixa mortalidade, a idade inferior a um ano não foi associada a um pior prognóstico, os pacientes com síndrome inflamatória multissistêmica apresentaram sintomas mais graves, biomarcadores inflamatórios mais elevados e uma grande predominância no sexo masculino, mas apenas a presença de comorbidades e doenças crônicas foi um preditor independente de gravidade.

Abstract Objective: To describe the clinical characteristics of children and adolescents admitted to intensive care with confirmed COVID-19. Method: Prospective, multicenter, observational study, in 19 pediatric intensive care units. Patients aged 1 month to 19 years admitted consecutively (March-May 2020) were included. Demographic, clinical-epidemiological features, treatment, and outcomes were collected. Subgroups were compared according to comorbidities, age < 1 year, and need for invasive mechanical ventilation. A multivariable logistic regression model was used for predictors of severity. Results: Seventy-nine patients were included (ten with multisystemic inflammatory syndrome). Median age 4 years; 54% male (multisystemic inflammatory syndrome, 80%); 41% had comorbidities (multisystemic inflammatory syndrome, 20%). Fever (76%), cough (51%), and tachypnea (50%) were common in both groups. Severe symptoms, gastrointestinal symptoms, and higher inflammatory markers were more frequent in multisystemic inflammatory syndrome. Interstitial lung infiltrates were common in both groups, but pleural effusion was more prevalent in the multisystemic inflammatory syndrome group (43% vs. 14%). Invasive mechanical ventilation was used in 18% (median 7.5 days); antibiotics, oseltamivir, and corticosteroids were used in 76%, 43%, and 23%, respectively, but not hydroxychloroquine. The median pediatric intensive care unit length-of-stay was five days; there were two deaths (3%) in the non- multisystemic inflammatory syndrome group. Patients with comorbidities were older and comorbidities were independently associated with the need for invasive mechanical ventilation (OR 5.5; 95% CI, 1.43-21.12; p = 0.01). Conclusions: In Brazilian pediatric intensive care units, COVID-19 had low mortality, age less than 1 year was not associated with a worse prognosis, and patients with multisystemic inflammatory syndrome had more severe symptoms, higher inflammatory biomarkers, and a greater predominance of males, but only comorbidities and chronic diseases were independent predictors of severity.

Abstract Introduction The association between prenatal Zika virus infection and hearing alterations in offspring has been the object of some studies, although few have assessed children without microcephaly. However, a current trend to include prenatal Zika virus exposure in the group of risk indicators for hearing loss is noted. Objective To present a series of 27 children prenatally exposed to the Zika virus submitted to multiple hearing assessments over time. Methods A cohort of children born to symptomatic mothers with laboratorial Zika virus infection confirmation during pregnancy was submitted to an otoacoustic emission test, auditory brainstem response test (automated, neurodiagnostic and frequency-specific), audiometry, and imitanciometry over a period of 36 months since birth. The hearing assessment was performed independently of the presence of microcephaly or other apparent signs of congenital Zika syndrome. Results The hearing tests presented predominantly normal results. Some children had signs of middle ear pathology. The only microcephalic child had normal electrophysiological tests, as well as preserved audiometric thresholds, but presented altered motor responses to sound. Conclusion Prenatal exposure to Zika virus does not always determine hearing impairment. This risk seems to be more associated to the severity of the central nervous system damage. Hearing screening and follow-ups of the affected children are important, as well as further research in this area.

Resumo Introdução: Possíveis associações entre a infecção pelo Zika vírus e perda auditiva foram observadas durante a epidemia nas Américas. Objetivo: Descrever as alterações auditivas, a patogênese e as recomendações de seguimento em indivíduos com infecção por Zika vírus pré-natal ou adquirida. Método: Uma pesquisa bibliográfica foi realizada em março/2018 a abril/2019 nas principais bases de dados disponíveis. A seleção dos artigos, extração de dados e avaliação de qualidade foram realizadas por dois revisores independentes. Estudos com avaliação auditiva de pacientes com infecção por Zika vírus congênita ou adquirida; e/ou hipóteses ou evidências sobre a fisiopatologia do comprometimento auditivo associado ao Zika vírus; e/ou recomendações sobre triagem e seguimento de pacientes com comprometimento auditivo pelo Zika vírus foram incluídos na pesquisa. Resultados: Um total de 27 artigos foram selecionados. Perdas auditivas neurossensorial e transitória foram relatadas em seis adultos com infecção pelo Zika vírus adquirida. Das 962 crianças estudadas, 482 apresentavam microcefalia e 145 tinham confirmação diagnóstica do Zika vírus; 515 das 624 crianças com avaliação auditiva haviam realizado apenas testes de triagem com teste de emissões otoacústicas e/ou teste de potencial evocado auditivo de tronco encefálico automático com estímulo clique. Estudos em crianças expostas no período pré-natal foram muito heterogêneos e grandes variações na frequência de emissões otoacústicas e potencial evocado auditivo de tronco encefálico automático alterados ocorreram ao longo dos estudos; alterações nas emissões otoacústicas variaram de 0% a 75%, enquanto as alterações no potencial evocado auditivo de tronco encefálico automático variaram de 0% a 29,2%. Não foi possível descartar comprometimento neurossensorial, retrococlear ou de origem central. Um estudo com camundongos infectados não encontrou dano microscópico nas células ciliadas da cóclea. Estudos sobre a patogênese das alterações auditivas em humanos estão limitados a hipóteses e recomendações ainda apresentam pontos de controvérsia. Conclusão: Os dados disponíveis ainda são insuficientes para compreender todo o espectro do envolvimento dos órgãos auditivos pelo Zika vírus, a patogênese desse envolvimento ou até mesmo para confirmar a associação causal entre o envolvimento auditivo e a infecção pelo vírus. As recomendações de triagem e seguimento ainda apresentam pontos de controvérsia.

Abstract Introduction: Possible associations between Zika virus infection and hearing loss were observed during the epidemic in the Americas. Objective: To describe the auditory alterations, pathogenesis and recommendations for follow-up in individuals with prenatal or acquired Zika virus infection. Methods: Bibliographic research conducted in March/2018-April/2019 at the main available databases. Article selection, data extraction and quality evaluation were carried out by two independent reviewers. Studies containing auditory evaluation of patients with congenital or acquired Zika virus infection; and/or hypotheses or evidences on the pathophysiology of auditory impairment associated with Zika virus; and/or recommendations on screening and follow-up of patients with auditory impairment by Zika virus were included. Results: A total of 27 articles were selected. Sensorineural and transient hearing loss were reported in six adults with acquired Zika virus infection. Of the 962 studied children, 482 had microcephaly and 145 had diagnostic confirmation of Zika virus; 515 of the 624 children with auditory evaluation performed only screening tests with otoacoustic emissions testing and/or automated click-stimuli auditory brainstem response testing. Studies in prenatally exposed children were very heterogeneous and great variations in the frequency of altered otoacoustic emissions and automated click-stimuli auditory brainstem response occurred across the studies. Altered otoacoustic emissions varied from 0% to 75%, while altered automated click-stimuli auditory brainstem response varied from 0% to 29.2%. Sensorineural, retrocochlear or central origin impairment could not be ruled out. One study with infected mice found no microscopic damage to cochlear hair cells. Studies on the pathogenesis of auditory changes in humans are limited to hypotheses and recommendations still include points of controversy. Conclusion: The available data are still insufficient to understand the full spectrum of the involvement of the auditory organs by Zika virus, the pathogenesis of this involvement or even to confirm the causal association between auditory involvement and virus infection. The screening and follow-up recommendations still present points of controversy.

RESUMO Objetivo: Avaliar a validade e a confiabilidade de um sistema de classificação de risco para emergências pediátricas (CLARIPED) desenvolvido no Brasil. Métodos: Fase de validade: estudo observacional prospectivo em crianças de 0 a 15anos atendidas consecutivamente no serviço de emergência pediátrica (SEP) de um hospital terciário entre 2 e 18de julho de 2013. Avaliou-se a associação dos níveis de urgência com desfechos clínicos (utilização de recursos, taxa de admissão no SEP, taxa de hospitalização e tempo de permanência no SEP); e comparou-se o desempenho do CLARIPED com um padrão de referência. Fase de confiabilidade interobservadores: uma amostra de conveniência de pacientes atendidos entre abril e julho de 2013 foi submetida a duas classificações de risco consecutivas e independentes, e estimou-se o Kappa ponderado quadrático. Resultados: Em 1.416 atendimentos realizados na fase de validade, a distribuição de níveis de urgência foi: 0,0% vermelho/emergência; 5,9% laranja/muito urgente; 40,5% amarelo/urgente; 50,6% verde/pouco urgente; e 3,0% azul/sem urgência. Ospercentuais de pacientes que usaram dois ou mais recursos diminuíram do nível laranja para o amarelo, verde e azul (81, 49, 22 e 2%, respectivamente, p<0,0001), assim como a taxa de admissão no SEP, o tempo de permanência no SEP e a taxa de admissão hospitalar. Asensibilidade para discriminar pacientes muito urgentes foi de 0,89 (intervalo de confiança de 95%- IC95% 0,78-0,95), e a taxa de subtriagem foi de 7,4%. Aconfiabilidade interobservadores em 191 pacientes classificados por duas enfermeiras foi substancial (kw2=0,75; IC95% 0,74-0,79). Conclusões: O sistema CLARIPED mostrou boa validade e substancial confiabilidade para classificação de risco em um serviço de emergência pediátrica.

ABSTRACT Objective: To assess the validity and reliability of a triage system for pediatric emergency care (CLARIPED) developed in Brazil. Methods: Validity phase: prospective observational study with children aged 0 to 15 years who consecutively visited the pediatric emergency department (ED) of a tertiary hospital from July 2 to 18, 2013. We evaluated the association of urgency levels with clinical outcomes (resource utilization, ED admission rate, hospitalization rate, and ED length of stay); and compared the CLARIPED performance to a reference standard. Inter-rater reliability phase: a convenience sample of patients who visited the pediatric ED between April and July 2013 was consecutively and independently double triaged by two nurses, and the quadratic weighted kappa was estimated. Results: In the validity phase, the distribution of urgency levels in 1,416 visits was the following: 0.0% red (emergency); 5.9% orange (high urgency); 40.5% yellow (urgency); 50.6% green (low urgency); and 3.0% blue (no urgency). The percentage of patients who used two or more resources decreased from the orange level to the yellow, green, and blue levels (81%, 49%, 22%, and 2%, respectively, p<0.0001), as did the ED admission rate, ED length of stay, and hospitalization rate. The sensitivity to identify patients with high urgency level was 0.89 (confidence interval of 95% [95%CI] 0.78-0.95), and the undertriage rate was 7.4%. The inter-rater reliability in 191patients classified by two nurses was substantial (kw2=0.75; 95%CI 0.74-0.79). Conclusions: The CLARIPED system showed good validity and substantial reliability for triage in a pediatric emergency department.

ABSTRACT Objectives: The role of viral co-detection in children with severe acute respiratory infection is not clear. We described the viral detection profile and its association with clinical characteristics in children admitted to the Pediatric Intensive Care Unit (PICU) during the 2009 influenza A(H1N1) pandemic. Method: Longitudinal observational retrospective study, with patients aged 0–18 years, admitted to 11 PICUs in Rio de Janeiro, with suspected H1N1 infection, from June to November, 2009. The results of respiratory samples which were sent to the Laboratory of Fiocruz/RJ and clinical data extracted from specific forms were analyzed. Results: Of 71 samples, 38% tested positive for H1N1 virus. Of the 63 samples tested for other viruses, 58 were positive: influenza H1N1 (43.1% of positive samples), rhinovirus/enterovirus (41.4%), respiratory syncytial vírus (12.1%), human metapneumovirus (12.1%), adenovirus (6.9%), and bocavirus (3.5%). Viral codetection occured in 22.4% of the cases. H1N1-positive patients were of a higher median age, had higher frequency of fever, cough and tachypnea, and decreased leukometry when compared to H1N1-negative patients. There was no difference in relation to severity outcomes (number of organic dysfunctions, use of mechanical ventilation or amines, hospital/PICU length of stay or death). Comparing the groups with mono-detection and co-dection of any virus, no difference was found regarding the association with any clinical variable. Conclusions: Other viruses can be implicated in SARI in children. The role of viral codetection has not yet been completely elucidated.

Resumo Objetivo: Apresentar um novo instrumento de classificação de risco pediátrico, o CLARIPED, e descrever as etapas de seu desenvolvimento. Métodos: Etapas do desenvolvimento: (i) primeira rodada de discussão entre especialistas, primeiro protótipo; (ii) pré-teste de confiabilidade, 36 casos hipotéticos; (iii) segunda rodada de discussão para ajustes; (iv) treinamento da equipe; (v) pré-teste com pacientes em tempo real; (vi) terceira rodada de discussão para novos ajustes; (vii) pré-teste final de validade (20% dos atendimentos de cinco dias). Resultados: O CLARIPED apresenta cinco categorias de urgência: Vermelha (emergência), Laranja (muito urgente), Amarela (urgente), Verde (pouco urgente) e Azul (sem urgência). A primeira etapa da classificação inclui a aferição de quatro sinais vitais (escore Vipe); a segunda etapa consiste na avaliação de discriminadores de urgência. Cada etapa resulta na atribuição de uma cor, seleciona-se a de maior urgência para a classificação final. Cada cor corresponde a um tempo máximo de espera pelo atendimento médico e ao encaminhamento à área física mais adequada à condição clínica do paciente. A concordância interobservador foi substancial (kappa=0,79) e o pré-teste final, com 82 atendimentos, evidenciou boa correlação entre a proporção de pacientes em cada categoria de urgência e o número de recursos usados (p<0,001). Conclusões: O CLARIPED é um instrumento para classificação de risco simples, objetivo e de fácil uso, cujos pré-testes sugerem boa confiabilidade e validade. Estudos em maior escala sobre sua validade e confiabilidade em diferentes contextos de saúde estão em curso e podem contribuir para a adoção de um sistema de classificação de risco pediátrico em âmbito nacional.

Abstract Objective: To present a new pediatric risk classification tool, CLARIPED, and describe its development steps. Methods: Development steps: (i) first round of discussion among experts, first prototype; (ii) pre-test of reliability, 36 hypothetical cases; (iii) second round of discussion to perform adjustments; (iv) team training; (v) pre-test with patients in real time; (vi) third round of discussion to perform new adjustments; (vii) final pre-test of validity (20% of medical treatments in five days). Results: CLARIPED features five urgency categories: Red (Emergency), Orange (very urgent), Yellow (urgent), Green (little urgent) and Blue (not urgent). The first classification step includes the measurement of four vital signs (VIPE score); the second step consists in the urgency discrimination assessment. Each step results in assigning a color, selecting the most urgent one for the final classification. Each color corresponds to a maximum waiting time for medical care and referral to the most appropriate physical area for the patient's clinical condition. The interobserver agreement was substantial (kappa=0.79) and the final pre-test, with 82 medical treatments, showed good correlation between the proportion of patients in each urgency category and the number of used resources (p<0.001). Conclusions: CLARIPED is an objective and easy-to-use tool for simple risk classification, of which pre-tests suggest good reliability and validity. Larger-scale studies on its validity and reliability in different health contexts are ongoing and can contribute to the implementation of a nationwide pediatric risk classification system.
