Sistemas de informaçöes hospitalares fonte complementar na vigiläncia e monitoramento das doenças de transmissäo vetorial / Hospital information system - complementary source for surveillance and monitoring of vector - borne diseases

RESUMO

Este trabalho teve como objeto exploar as potencialidades so Sistema de Informaçöes hospitalares - SIH/SUSna vigiläncia epidemilógica e monitoramento de doenças de transmissäo vetorial (dengue, leishmaniose, e febre amarela). Foram utilizados dados de internaçöes do SIH, do período de 1984 a 1998, e de notificaçäo de casos do Centro Nacional de Epidemilogia-CENEPI, do período de 1980 a 1997. Os dados demonstram que houve rssurgimento da dengue em 1982, registrando-se até 1997 poucas internaçöes quando se elevou a frequência don internamentos na regiäo Sudeste, Nordeste e Norte, indicando ocorrência de formas mais graves da doença. Já para a febre amarela, há icoerência entre os aspectos clínicos da doença e o grande número de internaçöes registradas, sugerindo erro sistemático na informaçäo hospitalar. Para a leishmaniose, observa-se coerência entre os dados do SIH e CENEPI, seguindo o caráter cíclico descrito para a doença. de um modo geral, o SIH demonstrou qualidade como fonte complementar de informaçöes na vigiläncia da dengue hemorrágica e lsishmaniose, e apresentou problemas no monitoramento da febre amarela, sugerindo ajustes ao sistema

ABSTRACT

The objective of this paper was to explore the potentialities of the Hospital Information System - SIH/SUS for epidemiologic surveillance and monitoring of vector-borne diseases (dengue, leishmaniasis, and yellow fever). Hospital admittance data from the SIH, during the period from 1984 to 1998, and from the case reporting system of the National Center of Epidemiology ­ CENEPI, during the period from 1980 to 1997 were used. The data demonstrate that there was resurgence of dengue in 1982, with small amount of hospital admittances up to 1997. In the latter year the frequency of admittances increased, mainly in the Southeast, Northeast and North regions, indicating the occurrence of severe dengue cases. Already for yellow fever, incoherence between the clinical aspects of the disease and the large number of admittances reported was observed, suggesting systematic errors in the hospital information system. For leishmaniasis, coherence was observed between SIH and CENEPI data, which showed the recurrent character described for this disease. In a general way, SIH demonstrated quality as a complementary source of information for surveillance of hemorrhagic dengue and leishmaniasis however, problems were detected for monitoring yellow fever, suggesting the need for system adjustments.
