We investigated the validity of the 10th Revision Canadian modification of International Statistical Classification of Disease and Related Health Problems (ICD-10-CA) diagnostic codes for surgery for benign gynaecologic conditions in the Canadian Institute for Health Information Discharge Abstract Database (CIHI-DAD), the main source of routinely collected data in Canada. Reabstracted data from patient charts was compared to ICD-10-CA codes and measures of validity were calculated with 95% confidence intervals. A total of 1068 procedures were identified. More objective, structural diagnoses (fibroids, prolapse) had higher sensitivity and near-perfect Kappa coefficients, while more subjective, symptomatic diagnoses (abnormal uterine bleeding, pelvic pain) had lower sensitivity and moderate-substantial Kappa coefficients. Specificity, positive predictive values, and negative predictive values were generally high for all diagnoses. These findings support the use of CIHI-DAD data for gynaecologic research.
我们研究了加拿大国际疾病分类第 10 次修订版（ICD-10-CA）用于良性妇科疾病手术的诊断代码在加拿大健康信息研究所出院摘要数据库（CIHI-DAD）中的有效性，该数据库是加拿大常规收集数据的主要来源。从患者病历中重新摘录的数据与 ICD-10-CA 代码进行了比较，并计算了 95%置信区间的有效性衡量标准。共确定了 1068 例手术。更客观、结构性的诊断（肌瘤、脱垂）具有更高的敏感性和近乎完美的 Kappa 系数，而更主观、症状性的诊断（异常子宫出血、盆腔疼痛）具有较低的敏感性和中度至大量的 Kappa 系数。所有诊断的特异性、阳性预测值和阴性预测值通常都很高。这些发现支持使用 CIHI-DAD 数据进行妇科研究。
