确定常规医疗护理过程中电子病历（EMR）中记录的成人体重和身高的有效性。电子病历允许在常规医疗护理过程中收集的数据用于许多领域的各种研究应用，包括流行病学和比较有效性研究。然而，熟悉临床试验中通常使用的仔细控制的测量方案的研究人员可能会质疑在常规临床护理过程中收集的数据的有效性。在一个研究项目中收集的体重和身高，重点是怀孕期间的体重增加，与研究参与者的医疗记录中一致记录的体重和身高测量值进行比较。对于体重测量（N=102），比较了±14天内记录的数据，对于身高测量（N=114），比较了±5年内记录的数据。我们使用一致性和组内相关系数以及Bland和Altman的一致性限度评估了医学和研究测量之间的一致性。研究和医疗记录中的平均体重测量值分别为99.3 kg和99.2 kg。体重的一致性和组内相关系数的估计值相似，分别为0.999和95%的置信区间[0.998，0.999]。95%的一致性限度为-1.5 kg和+1.7 kg。平均研究和医疗身高测量值分别为1.646 m和1.654 m，身高的一致性和组内相关系数分别为0.941和0.942。95%的一致性界限为-0.031 m和+0.047 m。对于孕妇，病历中记录的体重可与研究中记录的体重互换。医疗记录中记录的身高测量值不如体重那么一致，但医疗记录和研究身高测量值之间的一致性足够高，可以将其用于流行病学和比较有效性研究。
To determine the validity of adult body weights and heights recorded in electronic medical records (EMRs) in the course of routine medical care. EMRs allow the potential use of data collected in the course of routine medical care for a variety of research applications in many fields including epidemiology and comparative effectiveness studies. However, researchers familiar with carefully controlled measurement protocols typically used in clinical trials may question the validity of data collected in the course of routine clinical care. Weights and heights collected during a research project that focused on weight gain during pregnancy were compared to weight and height measurements coincidently recorded in the research participant’s medical records. For weight measures (N=102), data recorded within ±14 days were compared, and for height measures (N=114), data recorded within ±5 years were compared. We assessed agreement between medical and research measurements using the concordance and intraclass correlation coefficients, and Bland and Altman’s limits of agreement. The mean research and medical record weight measurements were 99.3 kg and 99.2 kg, respectively. The concordance and intraclass correlation coefficients for weight had similar estimates of .999 and 95 percent confidence intervals [.998, .999]. The 95 percent limits of agreement were −1.5 kg and +1.7 kg. The mean research and medical height measurements were 1.646 m and 1.654 m, respectively, and the concordance and intraclass correlation coefficients for height were .941 and .942, respectively. The 95 percent limits of agreement were −.031 m and +.047 m. For pregnant women, body weights documented in the medical record are exchangeable with body weights recorded in a research setting. Height measurements recorded in the medical records were not in as close agreement as weights, but concordance between medical record and research height measurements are high enough to allow them to be used epidemiological and comparative effectiveness research.
