Accuracy of cause-of-death coding in Taiwan: types of miscoding and effects on mortality statistics

Abstract

This study showed various levels of agreement for different diseases between the reviewer and the original coders in selection of the UCD. Owing to the 'compensatory effect of errors', the national mortality statistics were not affected significantly. The national administration should undertake routine internal studies to control the quality of UCD coding practices.

Prevalence and incidence in patients with autoimmune rheumatic diseases: A nationwide population‐based study in Taiwan

“…Survival status and date of death from 2000 -2008 were ascertained by using the Taiwan NDR, which records the cause of death for all deceased citizens. The accuracy of this coding system has been validated in previous studies (11). • This is the first nationwide population-based epidemiologic study on ARDs in Asia Taiwan.…”

U‐Shaped Association Between Serum Uric Acid Levels With Cardiovascular and All‐Cause Mortality in the Elderly: The Role of Malnourishment

“…It should be noted that the ideal BMI in this study was 22 kg/m 2 , which was more appropriate for Asian populations 28. Fourth, the causes of death were accurately identified from the Taiwan National Death Registry System31 and the survival status of all participants can be tracked. CVD mortality in our study accounted for 23.6% of all deaths, which is similar to the proportion (21.5%) of CVD mortality in the national statistics of cause of death 43…”

“…The study outcomes were all‐cause mortality ( ICD‐9 001.x–999.x or ICD‐10 A00.x–Z99.x) and CVD‐related death ( ICD‐9 393.x–459.x; ICD‐10 I07.x–I77.x, I99.x, J00.x, and J04.x). The accuracy of cause‐of‐death codes in Taiwan's National Death Registry database has been validated 31. All participants were followed until death or December 31, 2010, whichever occurred first.…”

Acurácia da equipe do Sistema de Informações sobre Mortalidade na seleção da causa básica do óbito em capital no Sul do Brasil

“…O Automated Classification of Medical Entities (ACME) considerou a causa básica do óbito incompatível com a afecção principal em 28% dos casos 6 . Quando as informações do registro hospitalar foram adicionadas à DO original, o ACME selecionou uma nova causa básica em 10,6% de um total de 39.872 óbitos hospitalares 6 . Em relação à avaliação da qualidade do trabalho da equipe responsável pelo SIM, foi encontrado apenas um estudo realizado em Taiwan, com dados de 1994 7 . Os autores identificaram uma concordância entre a codificação original e a revisada, para todas as causas, de acordo com a 9 a revisão da Classificação Internacional de Doenças (CID-9), de 80,9% para o terceiro dígito e de 83,9% para o segundo 7 .…”
