to assess the results of the investigation of ill-defined causes of death (IDCD) to improve the quality of cause-of-death data in Brazil.
this is a descriptive study using data from the Mortality Information System; all IDCD which occurred in 2010 were selected; deaths were analyzed according to macroregions, states, state capitals and characteristics of how the investigations were carried out.
the proportion of IDCD was 8.6% in Brazil in 2010 and decreased to 7.0% after investigation and fell from 4.7% to 3.4% in state capitals after investigation; approximately 65% of the investigated cases were reclassified to a defined cause in states and state capitals.
there was an improvement in data quality on cause of death resulting from these investigations which have led to an important decrease in the proportion of IDCD in the states and state capitals, although there are still some regional inequalities.
评估死因不明（IDCD）调查结果，以提高巴西死因数据质量。
这是一项描述性研究，使用来自死亡信息系统的数据；选取了2010年发生的所有死因不明情况；根据大区、州、州首府以及调查开展方式的特点对死亡情况进行分析。
2010年巴西死因不明的比例为8.6%，调查后降至7.0%，州首府调查后从4.7%降至3.4%；在州和州首府，约65%的被调查病例被重新归类为明确死因。
这些调查使死因数据质量得到改善，导致州和州首府死因不明的比例显著下降，尽管仍存在一些地区不平等现象。
