ABSTRACT

Objetivos. Evaluar si la taquipnea y las retracciones subcostales son predictoras eficientes para el diagnóstico de neumonía adquirida en la comunidad (NAC) en niños. Materiales y métodos. Se revisaron las bases de datos: PubMed, LILACS, The African Journal Database y The Cochrane Central Library. Se incluyeron estudios originales que evaluaron el rendimiento diagnóstico de los criterios clínicos de taquipnea o retracciones subcostales, definidos según los criterios de la Organización Mundial de la Salud (OMS) para el diagnóstico de NAC en niños de hasta cinco años de edad con tos y fiebre. Se estimaron las razones de probabilidades (LR), el odds ratio diagnostico (DOR) y sus respectivos intervalos de confianza al 95% (IC95%) para cada prueba clínica evaluada. Resultados. Se encontraron 975 estudios, incluyendo ocho en la revisión. Se enrolaron 4740 pacientes y analizaron 3584 (75%), de los cuales 916 (19%) tuvieron el diagnóstico de NAC. Al combinar los datos, la taquipnea obtuvo una LR positiva de 3,16, (IC95% 2,11-4,73) y una LR negativa de 0,36 (IC95% 0,23-0,57). El DOR fue de 10,63 (IC95% 4,4-25,66, I2=93%). Al realizar el análisis para retracciones subcostales se obtuvo un LR positivo de 2,49 (IC95% 1,41-4,37) y un LR negativo de 0,59 (IC95% 0,4-0,87). El DOR fue de 5,32 (IC95% 1,88-15,05, I2=89%). Conclusiones. Se puede tomar en cuenta la presencia o ausencia de taquipnea y retracciones subcostales en el diagnóstico de NAC, cabe considerar la incertidumbre relativa en su poder diagnóstico y los LR relativamente modestos. La confianza en estos resultados es baja por la inadecuada calidad de la evidencia en este tema.


Objectives. Determine whether tachypnea and subcostal retractions can be efficient predictors for the diagnosis of Community-Acquired Pneumonia (CAP) among children. Materials and methods. These were the databases used: PubMed, LILACS, The African Journal Database and The Cochrane Central Library. Original studies were included which assessed the diagnostic performance of the clinical criteria for tachypnea or subcostal retraction defined in accordance with the criteria of the World Health Organization (OMS) for CAP diagnosis in children ≤ 5 with cough and fever. The likelihood ratio (LR), the diagnosis odds ratio (DOR), and their respective confidence intervals at 95% (IC95%) were estimated for each clinical test. Results. 975 studies were found, eight were included in the review. 4740 patients were enrolled and 3584 (75%) were analyzed, 916 (19%) of which had a CAP diagnosis. When data were combined, tachypnea had a positive LR of 3.16, (95% CI 2.11-4.73) and a negative LR of 0.36 (95% CI 0.23-0.57). The DOR was 10.63 (95% CI 4.4-25.66, I2=93%). When subcostal retractions were analyzed, a positive LR of 2.49 (95%CI 1.41-4.37) and a negative LR of 0.59 (95%CI 0.4-0.87) were obtained. The DOR was 5.32 (95%CI 1.88-15.05, I2=89%). Conclusions. The presence or absence of tachypnea and subcostal retractions can be used in CAP diagnosis; it is worth considering the relative uncertainty in its diagnostic power and relatively modest LR. The confidence of these results is low due to the inadequate quality of the related evidence.
