巴西的死亡信息系统（MIS）记录医院和民事登记处的死亡率数据，负责编制根本死因。尽管管理信息系统不断改进，但一些地区因不明原因死亡的比例仍然很高。编码到这一类别的死亡很可能被认为是由传染性和非传染性疾病造成的错误编码死亡。然而，一些当地研究提供了巴西少报伤害的证据。本研究的目的是使用口头尸检 (VA) 方法调查不明确的死亡原因，以估计巴西米纳斯吉拉斯州东北部小城市的特定伤害死亡率。我们从 10 个城市中随机抽取了一些情况不明确的报告死亡证明样本，然后训练有素的访谈员使用标准化的 VA 调查问卷询问家庭成员，以获取死者生前经历的症状信息。我们已尽一切努力利用卫生机构记录来收集有关疾病或死亡的现有信息。医生根据国际疾病分类第十次修订版 (ICD-10) 的规则审查填写的问卷后确定可能的死亡原因。在 202 例符合条件的不明确死亡中，有 151 例使用 VA 方法进行了调查，其中 12.6% 的根本死因是受伤。调查后，伤害死亡率占所有死因的比例从4.4%上升至8.2%。在记录的伤害原因和 VA 检测到的伤害原因之间观察到不同的特定伤害类别原因。调查后发现，溺水是最主要的具体伤害原因。本研究提供的证据表明，使用 VA 来调查现有 MIS 中登记的不明确状况可以提供有关伤害作为米纳斯吉拉斯州小城市优先健康问题的相关性的信息。应引起区域卫生政策制定者的注意，以提高规划数据的质量。
The Mortality Information System (MIS) in Brazil records mortality data in hospitals and civil registries with the responsibility of compiling underlying cause of death. Despite continuous improvements in the MIS, some areas still maintain a high proportion of deaths assigned to ill-defined causes. Deaths coded to this category have most likely been considered as miscoded deaths from communicable and noncommunicable diseases. However, some local studies have provided evidence of underreporting of injury in Brazil. The aim of this study was to investigate ill-defined causes of death using the verbal autopsy (VA) method to estimate injury-specific mortality fraction in small municipalities in northeastern Minas Gerais, Brazil. A sample size of reported death certificates with ill-defined conditions in a random sample of 10 municipalities was obtained, and then trained interviewers questioned family members using a standardized VA questionnaire to elicit information on symptoms experienced by the deceased before death. All attempts were made to collect existing information about the disease or death using health facilities records. Probable causes of death were assigned by a physician after review of the completed questionnaires following rules of the 10th revision of the International Classification of Diseases (ICD-10). Of 202 eligible ill-defined deaths, 151 were investigated using the VA methodology, and 12.6% had injury as the underlying cause of death. The proportional mortality fraction from injury among all causes of death increases from 4.4% to 8.2% after investigation. Different specific injury category causes were observed between recorded injury causes and those detected by VA. Drowning was the top specific injury cause detected after investigation. This study provides evidence that the use of VA in the investigation of registered ill-defined conditions in an existing MIS can furnish information on the relevance of injury as a priority health problem in small municipalities of Minas Gerais. Local research with VA should be brought to the attention of regional health policymakers to improve the quality of data for their planning.
