目的 评估健康计划管理和索赔数据的有效性，以识别孕妇的孕前和妊娠糖尿病、肥胖和超声检查。方法 利用参与 HMO 研究网络的三个健康计划的管理和索赔数据进行回顾性研究。使用诊断、药物配药和程序代码来识别 2006 年 1 月至 2008 年 12 月期间怀孕的妇女的糖尿病、肥胖症和超声检查。随机抽取医疗图表样本 (n=222)。计算阳性预测值（PPV）。还计算了两个地点的电子病历中可获取体重指数数据的女性肥胖的敏感性。 结果 总体而言，222 例糖尿病病例中，有 190 例 (86%) 被确诊（82% 为妊娠期糖尿病，74% 为孕前糖尿病）。识别超声波的代码的 PPV 为 80%。而肥胖相关诊断代码的PPV较高(93%)，而敏感性较低(33%)。 结论 健康计划管理和索赔数据可用于准确识别孕前和妊娠期糖尿病和超声检查。肥胖的编码不一致。版权所有 (C) 2011 John Wiley & Sons, Ltd.
Purpose To evaluate the validity of health plan administrative and claims data to identify pre-gestational and gestational diabetes, obesity, and ultrasounds among pregnant women.Methods A retrospective study was conducted using the administrative and claims data of three health plans participating in the HMO Research Network. Diagnoses, drug dispensings, and procedure codes were used to identify diabetes, obesity, and ultrasounds among women who were pregnant between January 2006 and December 2008. A random sample of medical charts (n=222) were abstracted. Positive predictive values (PPVs) were calculated. Sensitivity also was calculated for obesity among women for whom body mass index data were available in electronic medical records at two sites.Results Overall, 190 of 222 cases of diabetes (86%) were confirmed (82% for gestational diabetes and 74% for pre-gestational diabetes). The PPV for codes to identify ultrasounds was 80%. Whereas the PPV for obesity-related diagnosis codes was high (93%), and the sensitivity was low (33%).Conclusions Health plan administrative and claims data can be used to accurately identify pre-gestational and gestational diabetes and ultrasounds. Obesity is not consistently coded. Copyright (C) 2011 John Wiley & Sons, Ltd.
