RESUMO
Introdução: O vírus influenza afecta
anualmente 10 a 40% das crianças e
destas 0,5 a 1% vão necessitar de internamento.
Ao averiguar a prevalência desta
infecção no internamento do Hospital
Dona Estefânia, entre Janeiro de 2004 e
Junho de 2006, constatámos a existência
de apenas nove casos diagnosticados.
Objectivos: Determinar as causas
da escassez do número de diagnósticos
de infecções pelo vírus influenza.
Materiais e Métodos: Para alcançar
o objectivo deste estudo foram consideradas
as seguintes hipóteses: 1) baixa
incidência de gripe sazonal no período
considerado 2) insuficiência do número
de pedidos para pesquisa do vírus pelo
corpo clínico 3) baixa identificação por
procedimentos técnicos incorrectos. Foram
analisados os pedidos de pesquisa
de vírus respiratórios e realizado um inquérito
ao corpo clínico e enfermagem
sobre os procedimentos técnicos de
diagnóstico. Os dados foram completados
através de consulta de processos clínicos.
O diagnóstico laboratorial foi realizado
por técnica de imunofluorescência
indirecta (Kit VRK®, Bartels).
Resultados: Após exclusão de várias
hipóteses identificámos procedimentos
técnicos incorrectos na metodologia
do diagnóstico utilizada, condicionando
uma baixa taxa de identificação vírus respiratórios - 23% (276 resultados positivos
em 1231 amostras).
Comentários: O diagnóstico da
gripe contribui para o controle da morbilidade
e mortalidade desta infecção.
Para que este processo seja efectivo é
essencial que os profissionais de saúde
sigam rigorosamente os procedimentos
que conduzem a um correcto diagnóstico
da doença. O insuficiente número
de casos detectados no nosso estudo
proporcionou-nos uma reflexão sobre a
metodologia empregue para que, futuramente,
se possa maximizar o número de
diagnósticos de infecções respiratórias
pelo vírus influenza.
ABSTRACT Background: Influenza virus yearly affects 10-40% of children and 0,5-1% of them will need hospital admission. While studying the prevalence of infl uenza virus infections in children admitted in Hospital de Dona Estefânia (Lisbon) during January 2004 and June 2006, the authors found only nine diagnosed cases of influenza. Aims: To identify the possible causes of the detected lack of influenza diagnosis during that length of time. Methods: The authors considered the following hypothesis: 1) low incidence of Influenza infections during the period of the study; 2) insufficient clinical requests for investigate Influenza as a possible aetiology of respiratory infections; 3) Low detection caused by errors in technical procedures used in the diagnostic methodology. The requests for laboratorial diagnosis of Influenza were analyzed and an inquiry about technical procedures in Influenza laboratorial diagnosis was made to nurses and clinical staff. The information was completed with consultation of the patient files. The laboratorial diagnosis was made using indirect immunofluorescence assay (Kit VRK®, Bartels). Results: We found that the most important cause of the lack of diagnosis was the existence of errors in technical procedures used in the diagnostic methodology, leading to a low rate of respiratory virus identification – 23% . Comments: The exact influenza diagnosis helps in the surveillance of its morbidity and mortality. In order to do it correctly, all health care professionals need to rigorously carry on the accurate procedures that lead to the proper diagnosis of this disease. In our case, the insufficient number of diagnosis gave us the opportunity to refl ect about the applied methodology so that, in the future, we can maximize the number of diagnosis of influenza respiratory tract infections.
