Evaluation of the quality of data in the Live Birth Information System and the Information System on Mortality during the neonatal period in the state of Espírito Santo, Brazil, between 2007 and 2009

摘要

Health information systems make it possible to be aware of health problems and often represent the sole source of information, thereby making it essential to assess their quality. The scope of this paper was to evaluate the quality of data about live births and deaths in the neonatal period in the Live Births Information System (SINASC) and Mortality Information System (SIM) in the state of Esp?-rito Santo during the period from 2007 to 2009. Descriptive methodology with secondary data obtained from the electronic address of the Informatics Department of the Unified Health System was used to analyze the dimensions of quality of information, namely accessibility, timeliness and completeness. The results indicate that the information is accessible and timely, with a lag of three years compared to the beginning of the study. The completeness of the variables analyzed in SINASC was predominantly classified as excellent. SIM revealed a high percentage of missing data on the number of the Live Birth Declaration, mother's education, age and reproductive history. The conclusion reached is that SINASC is an excellent source of information about births, though SIM reveals a marked need for improvements in the completeness of its information.
