Introduction In 2012, the Louisiana (LA) Department of Health and Hospitals revised the LA birth certificate to include medical reasons for births before 39 completed weeks' gestation. We compared the completeness and validity of these data with hospital discharge records. Methods For births occurring 4/1/2012-9/30/2012 at Woman's Hospital of Baton Rouge, we linked maternal delivery and newborn birth data collected through the National Perinatal Information Center with LA birth certificates. Among early term births (37-38 completed weeks' gestation), we quantified the reasons for early delivery listed on the birth certificate and compared them with ICD-9-CM codes from Woman's discharge data. Results Among 4353 birth certificates indicating delivery at Woman's Hospital, we matched 99.8% to corresponding Woman's administrative data. Among 1293 early term singleton births, the most common reasons for early delivery listed on the birth certificate were spontaneous active labor (57.5%), gestational hypertensive disorders (15.3%), gestational diabetes (8.7%), and premature rupture of membranes (8.1%). Only 2.7% of births indicated "other reason" as the only reason for early delivery. Most reasons for early delivery had >80% correspondence with ICD-9-CM codes. Lower correspondence (35 and 72%, respectively) was observed for premature rupture of membranes and abnormal heart rate or fetal distress. Discussion There was near-perfect ability to match LA birth certificates with Woman's Hospital records, and the agreement between reasons for early delivery on the birth certificate and ICD-9-CM codes was high. A benchmark of 2.7% can be used as an attainable frequency of "other reason" for early delivery reported by hospitals. Louisiana implemented an effective mechanism to identify and explain early deliveries using vital records.
引言 2012年，路易斯安那州（LA）卫生与医院部修订了LA出生证明，将妊娠39周之前分娩的医学原因纳入其中。我们将这些数据的完整性和有效性与医院出院记录进行了比较。方法 对于2012年4月1日至2012年9月30日在巴吞鲁日妇女医院发生的分娩，我们将通过国家围产期信息中心收集的产妇分娩和新生儿出生数据与LA出生证明进行了关联。在早产（妊娠37 - 38周）中，我们对出生证明上列出的早产原因进行了量化，并将其与妇女医院出院数据中的ICD - 9 - CM编码进行了比较。结果 在4353份表明在妇女医院分娩的出生证明中，我们将99.8%与相应的妇女医院管理数据进行了匹配。在1293例早产单胎分娩中，出生证明上列出的早产最常见原因是自发活跃分娩（57.5%）、妊娠期高血压疾病（15.3%）、妊娠期糖尿病（8.7%）和胎膜早破（8.1%）。只有2.7%的分娩将“其他原因”列为早产的唯一原因。大多数早产原因与ICD - 9 - CM编码的对应率>80%。胎膜早破以及异常心率或胎儿窘迫的对应率较低（分别为35%和72%）。讨论 将LA出生证明与妇女医院记录进行匹配的能力近乎完美。出生证明上早产原因与ICD - 9 - CM编码之间的一致性很高。2.7%的基准可作为医院报告的早产“其他原因”的可达到频率。路易斯安那州实施了一种有效的机制，利用生命记录来识别并解释早产情况。
