| Summary: | OBJECTIVE: To propose a tuberculosis-related death surveillance strategy based on the Brazilian Mortality Information System. METHODS: Data on 55 tuberculosis-related deaths, which occurred in two large hospitals in Rio de Janeiro, Southeastern Brazil, between September 2005 and August 2006, were obtained from the SIM. These cases were searched and compared with cases in the National Notification System (Sinan). The increment in the number of notifications and completeness of data were evaluated, as well as entry type and outcome in Sinan. RESULTS: Of the 55 deaths, 28 were registered in Sinan. Comparison between systems allowed for the following corrections: 27 new cases were notified, 14 new notifications performed by the hospitals where death occurred and ten outcomes corrected. This represented an increment of 41/144 (28%) notifications by these two hospitals in 2006. Nine cases, previously classified as unconfirmed tuberculosis were reclassified as bacteriologically confirmed, and another five cases were reclassified from tuberculosis to AIDS as the primary cause of death. CONCLUSIONS: The proposed surveillance system for tuberculosis-related death was useful to increase data completeness, decrease under-notification and cases with unknown outcome, to evaluate epidemiological surveillance and death certificate quality and to trace previously unidentified contacts.Original Abstract: OBJETIVO: Propor estrategia de vigilancia de obitos relacionados a tuberculose com base no Sistema de Informacao de Mortalidade. METODOS: Dados sobre os 55 obitos relacionados a tuberculose, ocorridos em dois hospitais de grande porte do Rio de Janeiro entre setembro de 2005 e agosto de 2006, foram obtidos no Sistema de Informacao de Mortalidade. Esses casos foram confrontados com os registros no Sistema de Informacao de Agravos de Notificacao (Sinan). O incremento no numero de notificacoes e na completitude dos dados foi avaliado, bem como o tipo de entrada e desfecho no Sinan. RESULTADOS: Dos 55 obitos, 28 estavam notificados no Sinan. O relacionamento dos sistemas possibilitou as seguintes correcoes: 27 casos novos notificados, 14 novas notificacoes realizadas pela unidade em que ocorreu o obito e o encerramento de dez notificacoes. Isso representou incremento de 41 (28%) notificacoes as 144 realizadas pelos dois hospitais em 2006. Nove casos foram reclassificados da condicao de tuberculose sem confirmacao para tuberculose com confirmacao diagnostica, e cinco casos foram reclassificados de tuberculose para Aids como causa basica de morte. CONCLUSOES: A vigilancia de obitos por tuberculose proposta permitiu aumentar a completitude dos sistemas de informacao, diminuir a subnotificacao e o numero de casos nao encerrados, supervisionar a vigilancia epidemiologica das unidades e a qualidade do preenchimento das declaracoes de obito, alem de buscar contatos nao avaliados pela equipe de saude. |
