Objective.我们评估了2003年修订的美国活产标准证书上所选项目的有效性，以了解新项目和现有项目的准确性。我们计算了2009年纽约市（n=603）和佛蒙特州（n=664）活产婴儿代表性样本的出生证明上报告的选定变量的敏感性、特异性、阳性预测值（PPV）和阴性预测值（NPV）。在这两个地点，敏感性是极好的（>90%），医疗补助覆盖率在分娩，任何以前的活产，和目前的交付方法;敏感性是中度（70%-90%），妊娠期糖尿病;和敏感性差（90%）的特异性和NPV。需要进一步研究，以确定如何最好地提高出生证数据的质量。今后修订出生证时，可考虑删除那些一直证明难以准确报告的项目。
Objective. We assessed the validity of selected items on the 2003 revised U.S. Standard Certificate of Live Birth to understand the accuracy of new and existing items.Methods. We calculated sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of select variables reported on the birth certificate using the medical record as the gold standard for a representative sample of live births in New York City (n=603) and Vermont (n=664) in 2009.Results. In both sites, sensitivity was excellent (>90%) for Medicaid coverage at delivery, any previous live births, and current method of delivery; sensitivity was moderate (70%-90%) for gestational diabetes; and sensitivity was poor (90%) specificity and NPV.Conclusion. Further research is needed to determine how best to improve the quality of data on the birth certificate. Future revisions of the birth certificate may consider removing those items that have consistently proven difficult to report accurately.
