本研究检查了医疗记录与研究者测量的成人身高和体重之间的一致程度，并评估了ani的临床意义；导致体重指数（BMI） （kg/m(2)）根据体重不足，正常体重和超重的分类的差异。采用择期行冠状动脉旁路移植术的老年患者的医疗记录和研究者测量的身高（n = 85）、术前体重（n = 84）和术后体重（n = 65）进行分析。研究者测量的身高和体重由同一个人获得，并与医疗记录前提取的身高和体重进行比较。使用Bland和Altman的一致限度法来确定病历与研究者值之间的测量误差程度。根据医疗记录和研究人员的测量，使用Cohen's kappa来评估BMI类别差异的临床意义。对于身高，7%的数值超出了95%的一致性限制。对于术前和术后体重，只有不到5%的值超出95%的一致性范围。在医疗记录和研究者测量之间，使用Cohen's kappa进行BMI分类没有显著差异。虽然医疗记录中的身高测量可能存在一些误差，但体重测量的误差可能较小，而且测量误差的大小可能与临床无关。从医疗记录中提取的身高和体重测量对于接受择期手术的患者是可靠和准确的，对于稳定的术后患者也是如此。
This study examined the extent of agreement between medical record and researcher measures of height and weight in adults and assessed the clinical significance of ani; resulting differences in body mass index (BMI) (kg/m(2)) according to the categorizations of underweight, normal weight, and overweight. Medical record and researcher measurements for height (n = 85), preoperative weight (n = 84), and postoperative weight (n = 65) in older patients undergoing elective coronary artery bypass grafting were used for analysis. Researcher measurements of height and weight were obtained by the same person and were compared to height and weight measurements extracted front the medical record. Bland and Altman's limits of agreement method was used to determine the extent of measurement error between medical record and researcher values. Cohen's kappa was used to assess for clinical significance of the differences in BMI categories based on medical record and researcher measurements. For height, 7% of the values were outside the 95% limits of agreement. For preoperative and postoperative weight, less than 5% of the values were outside the 95% limits of agreement. There were no significant differences in BMI categorization using Cohen's kappa between medical record and researcher measurements. Although there may be some measurement error for height in the medical record, weight measurements may have less error and the amount of measurement error may not be clinically relevant. Height and weight measurements extracted from the medical record are reliable and accurate in patients admitted for elective surgery, as are weight measurements obtained in stable postoperative patients.
