目的：为了研究有效性的国际疾病分类，第9版，临床修改（ICD-9-CM）的代码在出院数据中识别婴儿心脏缺陷根据surveillance guidelines.Study Design：回顾性病历审查出生于2001年在明尼苏达州明尼阿波利斯市的一家医院的婴儿。使用ICD-9-CM编码从出院数据中识别婴儿，并在医疗记录中使用关键词。结果：在2,697名儿童中，ICD-9-CM编码识别出66名编码为心脏缺陷的婴儿;医生审查确认24名有心脏缺陷。85个ICD-9-CM编码中只有35个（41.2%）准确反映了心脏缺陷诊断。额外的病例发现发现了4名婴儿的5个心脏缺陷。ICD-9-CM编码识别这些婴儿的敏感性为0.857，阳性预测值为0.364。结论：ICD-9-CM编码从出院数据中识别出大多数婴儿心脏缺陷，但也有许多假阳性。ICD-9-CM代码对特定心脏缺陷不准确。
OBJECTIVE: To examine validity of the International Classification of Diseases, 9th Edition, Clinical Modification (ICD-9-CM) codes in discharge data for identifying infants with cardiac defects according to surveillance guidelines.STUDY DESIGN: Retrospective medical record review of infants born in 2001 at one hospital in Minneapolis, Minnesota. Infants were identified using ICD-9-CM codes from hospital discharge data, and keywords in medical records.RESULTS: Of 2,697 children, ICD-9-CM codes identified 66 infants coded with cardiac defects; physician review confirmed 24 had cardiac defects. Only 35 of 85 (41.2%) ICD-9-CM codes accurately reflected the cardiac defect diagnoses. Additional case finding located four infants with five cardiac defects. Sensitivity of ICD-9-CM codes for identifying these infants was 0.857, predictive value positive was 0.364.CONCLUSIONS: ICD-9-CM codes from hospital discharge data identified most infants with cardiac defects, but many were false positives. ICD-9-CM codes were inaccurate for specific cardiac defects.
