Resumen
GRASSI, Paulo R. y LAURENTI, Ruy. Implicações da introdução da 10a revisão da Classificação Internacional de Doenças em análise de tendência da mortalidade por causas. Inf. Epidemiol. Sus [online]. 1998, vol.7, n.3, pp.43-47. ISSN 0104-1673. http://dx.doi.org/10.5123/S0104-16731998000300005.
The International Classifcation of Diseases (ICD) is periodically revised (usually every tenyears). A new revision incorporates new diseases or else one particular disease, previously represented by a single code, can now be represented by two or more codes. Also, a disease may be moved from one chapter to another. The International Rules for Codification can also be changed in the new classification. These changes may be responsible for the increase or decrease infrequency of a disease or to a chapter of ICD, changing abruptly the trends of this disease or diseases. The ICD-10 for mortality was introduced in Brazil in 1996; a preliminary evaluation of the impact in the mortality statistics was made using the Data Bank of the Brazilian Information System of Mortality in the State of Rio Grande do Sul. In ICD -10 some selected diseases were moved to the chapter of infectious and parasitic diseases, some from this chapter to others. The death certificates of 1996/1997 were coded according to ICD -9 and ICD -10 and, with the use of ICD -10, the results showed an increase of 67,9%. Since the same cases were coded according to ICD-9 and ICD -10, it may be concluded that the increase was due to a "statistical artifact" and not to a real increase of infectious and parasitic diseases.
