摘要:We sought to estimate the accuracy, relative to maternal medical records, of perinatal risk factors recorded on fetal death certificates. We conducted a validation study of fetal death certificates among women who experienced fetal deaths between 1996 and 2001. The number of previous births, established diabetes, chronic hypertension, maternal fever, performance of autopsy, anencephaly, and Down syndrome had very high accuracy, while placental cord conditions and other chromosomal abnormalities were reported inaccurately. Additional population-based studies are needed to identify strategies to improve fetal death certificate data. Rates of fetal mortality declined dramatically in the United States in the decades preceding 1990. 1 However, since 1990, US fetal mortality rates have remained steady at between 6.7 and 7.5 per 1000 births. These trends in fetal mortality rates and the limited understanding of the etiology of fetal death are so compelling that the Centers for Disease Control and Prevention, as well as the National Institutes of Health, have identified this as a high priority area for epidemiological research. 2 , 3 One national research goal is to improve the quality and completeness of fetal death certificates, which are currently the major source of data on stillbirths. 2 , 3 No studies have assessed the accuracy of the information on perinatal risk factors in fetal death certificates compared with medical records. Thus, we examined the validity of fetal death certificates for identifying risk factors among women experiencing stillbirths in a tertiary care center in Washington State.
