评估出生证明对早产史的敏感性，并确定遗漏是否是随机或系统性偏倚。在地区数据库中确定了发生早产随后妊娠的受试者。变量"先前早产"从随后怀孕的出生证明中提取。比较了正确编码与错误编码的受试者的临床特征。确定了713例受试者，其中65.5%在随后的妊娠中正确编码。与正确编码的患者相比，未正确识别的患者倾向于发生晚期和非复发性早产或继发于母体或胎儿适应症的分娩。在随后的妊娠中早产的复发也与正确的编码有关。出生证明对早产史的总体敏感性是次优的。遗漏不是随机的，与当前和以前分娩的产科特征有关。因此，由此产生的关联可能是有缺陷的。
To assess the sensitivity of birth certificates to preterm birth history and determine whether omissions are randomly or systemically biased. Subjects who experienced a preterm birth followed by a subsequent pregnancy were identified in a regional database. The variable "previous preterm birth" was abstracted from birth certificates of the subsequent pregnancy. Clinical characteristics were compared between subjects who were correctly versus incorrectly coded. 713 subjects were identified, of whom 65.5% were correctly coded in their subsequent pregnancy. Compared to correctly coded patients, patients who were not correctly identified tended to have late and non-recurrent preterm births or deliveries that were secondary to maternal or fetal indications. A recurrence of preterm birth in the subsequent pregnancy was also associated with correct coding. The overall sensitivity of birth certificates to preterm birth history is suboptimal. Omissions are not random, and are associated with obstetrical characteristics from both the current and prior deliveries. As a consequence, resulting associations may be flawed.
