Accuracy of Birth Certificate Data Regarding the Amount, Timing, and Adequacy of Prenatal Care Using Prenatal Clinic Medical Records as Referents

Abstract

This study compared birth certificate data on the amount, timing, and adequacy of prenatal care with the same data abstracted from the prenatal clinic records of 2,032 women who attended a health department prenatal clinic in northeast Georgia from 1980 to 1988. Overall accuracy was poor. Only 14.3% (n = 291) of the records completely agreed on the total number of visits, while approximately 36% (n = 738) and 53% (n = 1,081) agreed within one visit and two visits, respectively. Complete agreement for month and trimester prenatal care began was 31.1% (n = 632) and 50.6% (n = 1,202), respectively. Because of the small geographic region included in the current study, the generalizability of these findings to other populations may be limited. Am J Epidemiol1997;145:68–71.
