Abstract

Cuando una crisis epidemiológica recrudece, el exceso de mortalidad publicado diariamente por MoMo (CNE-Instituto de Salud Carlos III) está gravemente sesgado a la baja. La razón es que el retraso habitual en la notificación de las defunciones se prolonga precisamente en esos momentos en los que dichas estimaciones tienen mayor relevancia social y epidemiológica. Proponemos ajustar los datos diarios (o “en tiempo real†) aplicando proyecciones en el futuro de revisiones observadas de datos ya publicados. Dichas revisiones suman defunciones que se notifican con retraso a excesos de mortalidad ya anunciados. Aplicamos este método a los excesos de mortalidad publicados por MoMo entre el 15 de abril y el 25 de mayo de 2020 durante la crisis del COVID-19 en España. Las correcciones basadas en los modelos polinómicos reducen entre un 18 y un 25% la raíz del error cuadrático medio (RMSE) de los datos “en tiempo real†.
