[Reliability of the diagnoses of hospital admissions for external causes financed by the Brazilian Unified Health System-SUS in two cities in the State of Paraná, Brazil]. / Confiabilidade dos diagnósticos de internações por causas externas financiadas pelo Sistema Único de Saúde em dois municípios do Estado do Paraná, Brasil.

The scope of this article is to analyze the reliability of the diagnoses of hospital admissions for external causes financed by the Brazilian Unified Health System (SUS). The diagnoses for hospital admissions from the Hospital Information System (SIH-SUS) data were compared with those from the research panel created from information culled from authorizations for hospital admission (AIH) complemented with information from other sources. The reliability was analyzed in groups using crude agreement and Kappa statistics. The crude agreement was 41.1% in Londrina and 15.8% in Maringá and the highest reliability was found for groupings for self-inflicted lesions and traffic accidents in Londrina (Kappa 0.57 and 0.56) while in Maringá reliability was acceptable for self-inflicted lesions (Kappa 0.28). The low agreement with differentiated standards according to groupings of causes and according to the municipalities highlight the fact that efforts must be made to improve the quality and use of the SIH-SUS in order to understand and intervene in accidents and violence in Brazil.

O objetivo deste artigo é analisar a confiabilidade dos diagnósticos de internações por causas externas do Sistema Único de Saúde (SUS). Os diagnósticos de internação do Sistema de Informações Hospitalares-SUS (SIH-SUS) foram comparados aos do banco pesquisa, construído com informações das autorizações de internação hospitalar (AIH) complementadas por outras fontes. A confiabilidade foi analisada por agrupamentos utilizando concordância bruta e estatística Kappa. A concordância bruta foi de 41,1% em Londrina e 15,8% em Maringá e a melhor confiabilidade foi a moderada para os agrupamentos das lesões autoprovocadas e acidentes de transporte em Londrina (kappa 0,57 e 0,56), ao passo que em Maringá foi a aceitável para as lesões autoprovocadas (kappa 0,28). As baixas concordâncias com padrões diferenciados segundo os agrupamentos de causas e segundo os municípios evidenciam que esforços devem ser empreendidos para melhorar a qualidade e utilização do SIH-SUS para conhecer e intervir nos acidentes e violências no Brasil.
