Abstract(s)
Em 2021, em Portugal, foi implementado um sistema de vigilância sentinela
de infeções respiratórias agudas graves (SARI) baseado em registos de
saúde eletrónicos hospitalares. O presente artigo tem como objetivo apresentar
este sistema de vigilância assim como os dados recolhidos, nas duas
unidades hospitalares envolvidas, a partir de outubro de 2023.
São incluídos na vigilância os indivíduos internados ( 24 horas) aos quais
seja atribuído pelo menos um código CID-10 (Classificação Internacional
de Doenças, 10ª revisão) associado a SARI. Os indicadores de vigilância
incluem a incidência de SARI, a proporção de SARI entre o total de hospitalizações
e a fração etiológica atribuível ao SARS-CoV-2, gripe e vírus
sincicial respiratório. Estes indicadores são analisados para o total de população
em observação e estratificados por grupo etário.
Entre a semana 40/2023 e 15/2024, foram reportados 2261 casos de SARI,
com a semana 53/2023 a apresentar a incidência mais elevada (19,7/100
000 habitantes). Relativamente à idade, a incidência mais elevada tem sido
observada em indivíduos com mais de 65 anos. A pesquisa de agentes infeciosos
respiratórios permitiu constatar que os vírus da gripe foram os mais
frequentemente detetados (45,2 %), seguidos de vírus sincicial respiratório
(32,2%) e SARS-CoV-2 (22,6%).
Este sistema de vigilância sentinela pretende assim contribuir para uma visão
compreensiva das infeções respiratórias em Portugal.
In 2021, in Portugal, a sentinel sur veillance system for severe acute respiratory infections (SARI) was implemented based on hospital electronic health records. This ar ticle aims to present this sur veillance system as well as the data collected, in the two hospital units involved, from October 2023. Hospitalized individuals ( ≥ 24 hours) who are assigned at least one of ICD-10 (International Classif ication of Diseases, 10th revision) codes associated with SARI are included in the sur veillance. Sur veillance indicators include the incidence of SARI, the propor tion of SARI among total hospitalizations, and the etiological fraction at tributable to SARS-CoV-2, inf luenza and respiratory syncytial virus. These indicators are analyzed for the total population under obser vation and stratif ied by age group. Between week 40/2023 and 15/2024, 2261 cases of SARI were repor ted, with week 53/2023 showing the highest incidence (19,7/100 000 inhabitants). Regarding age, the highest incidence has been obser ved in individuals over 65 years of age. Research into respiratory infectious agents revealed that inf luenza viruses were the most frequently detected (45,2%), followed by respiratory syncytial virus (32,2%) and SARS-CoV-2 (22,6%). This sentinel sur veillance system thus aims to contribute to a comprehensive view of respiratory infections in Portugal.
