[Completeness of data on live birth certificates and death certificates for early neonatal and fetal deaths in the Ribeirão Preto Region, São Paulo State, Brazil, 2000-2007].

This study aimed to evaluate the completeness of data on nine items included in both the certificate of live birth (CLB) and death certificate (DC), as well as the retrieval of data on early neonatal deaths. The study assessed live birth and early neonatal and fetal death records in municipalities in the Ribeirão Preto Region, São Paulo State, Brazil, from 2000 to 2007. Database matching for live births and deaths allowed retrieving data on early neonatal deaths. Data completion was good on the CLB and poor on the DC. Retrieval of data related to mortality was satisfactory, except for maternal schooling, number of live born children, and stillbirths. The findings highlight the need to improve completion of the DC and showed that the retrieval process improved the completeness of data from the database on early neonatal deaths. The use of reports on local investigation of deaths is recommended as a strategy to make mortality databases more complete.
