Exploratory development of automated coding software on the underlying causes of death / 中华流行病学杂志

To develop an automated coding software related to the underlying causes of death,based on the National Registration Information System on deaths,which could improve the quality of coding on the underlying causes of death in the conventional death surveillance system.Following the coding roles of the underlying death cause of ICD-IO and the design on principles of software of underlying death cause automated coding from some other countries,as well as in accordance with the coding strategy table from the USA,we implemented the automatization of the underlying death cause coding.Based on national registration information system on cause of death,an automated coding software of underlying death cause was developed with the coding correction rate closed to 85%.The automated coding software of underlying death cause could code the death cases of underlying death cause with high rate of correction,similar to that of the same kind softwares developed in other countries.

Avaliação da qualidade das informações em declarações de óbitos infantis / Assessment of the quality of information in infant's death certificates

OBJETIVOS: avaliar a qualidade das informações nas declarações de óbitos infantis e a confiabilidade da causa básica do óbito em menores de um ano de idade. MÉTODOS: Foram investigadas todas as declarações de óbitos de menores de um ano ocorridos de 2002 a 2005, cujas mães informavam residência em Montes Claros, Minas Gerais, na ocasião do óbito. Para verificar a confiabilidade da causa básica do óbito, foram selecionadas as declarações de óbitos infantis registrados em 2004 e uma certidão de óbito nova foi preenchida (DO Nova) para comparação com a original (DO Original) com base nos registros hospitalares. O teste de kappa foi usado para comparar o nível de concordância. RESULTADOS: verificou-se elevada proporção de dados faltosos nas declarações de óbitos infantis. Observou-se que a confiabilidade da causa básica do óbito somente foi considerada excelente para o grupo das malformações congênitas (kappa=0,83). Havia concordância moderada para o grupo mais comum, de causas relacionadas com a prematuridade (kappa=0,57). A concordância foi baixa para o grupo das causas infecciosas (kappa=0,24). CONCLUSÕES: Constatou-se a necessidade de melhoria da qualidade do preenchimento da declaração do óbito infantil.

OBJECTIVES: to assess the quality of the information in infants'death certificates and reliability of the reported underlying death cause in children under one year old. METHODS: information was obtained from all death certificates of children under one year old between 2002 and 2005 whose mothers declared their addresses as being Monte Claros, Minas Gerais when death occurred. To verify report reliability of the underlying death cause, children's death certificates issued in 2004 and a new death certificate was filled (New Death Certificate) to be compared with the ori-ginal (Original Death Certificate) based on hospital records. The kappa test was used for concordance level comparison. RESULTS: there was a high rate of missing data in infants'death certificates. Reliability of the underlying death cause was considered excellent only for the congenital malformation group (kappa=0.83). A moderate concordance was noted for the more common prematurity related causes (kappa=0.57). The lowest concordance related to the infection death cause group (kappa=0.24). CONCLUSIONS: the need for quality improvement in the information contained in children's death certificates was verified.
