Congenital heart surgery databases are tools for internal programmatic evaluation, benchmarking institutional results to multi-institutional aggregate data, and research. Therefore, it is essential to ensure the completeness and accuracy of data. This study analyzes the results of ten years of on-site source data verification of the European Congenital Heart Surgeons Association Congenital Heart Surgery Database (ECHSA CHSD).
All data forms verified between 2009 and 2018 were analyzed. The data form consists of 12 data elements: dates of birth, admission, surgery, discharge, and death; weight; case category; cardiopulmonary bypass time; aortic cross-clamp time; validation rules; diagnoses; and procedures. Descriptive data calculation and rates of completeness and accuracy were determined. The trend of error rate of seven centers with ≥5 visits was analyzed.
Sixty-nine on-site verification visits took place at 17 centers. A total of 26,245 cases were verified; 2,841 of these 26,245 cases (10.8%) showed an error. The total mean error rate of centers for all years was 12.3 ± 2.1%. Rates of completeness and accuracy were 99% and 89.2%, respectively. Coded diagnoses and procedure analysis revealed that 716 (2.7%) and 456 (1.7%) datasets were incorrect, respectively. Rates of completeness and accuracy of dates were 100%, and 97.1%, respectively. Validation fields showed no errors.
Source data verification is an appropriate tool to determine completeness and accuracy of data. The ECHSA CHSD verification analysis of a ten-year period showed a high level of completeness and accuracy. The verified data of the ECHSA CHSD are well-suited for benchmarking and research.
先天性心脏病手术数据库是内部计划评估、将机构结果与多机构汇总数据进行基准比较以及研究的工具。因此，确保数据的完整性和准确性至关重要。本研究分析了欧洲先天性心脏病外科医生协会先天性心脏病外科手术数据库（ECHSA CHSD）十年现场源数据验证的结果。
分析了 2009 年至 2018 年期间验证的所有数据表单。该数据表单包含 12 个数据元素：出生日期、入院日期、手术日期、出院日期和死亡日期；体重；病例类别；体外循环时间；主动脉阻断时间；验证规则；诊断；和手术程序。确定了完整性和准确性的完整数据计算和比率。分析了 7 个访问量≥5 的中心的错误率趋势。
在 17 个中心进行了 69 次现场验证访问。共验证了 26245 例；在这 26245 例中，有 2841 例（10.8%）出现错误。所有年份中心的总平均错误率为 12.3±2.1%。完整性和准确性的比率分别为 99%和 89.2%。编码诊断和程序分析显示，分别有 716（2.7%）和 456（1.7%）数据集不正确。日期的完整性和准确性比率分别为 100%和 97.1%。验证字段未显示错误。
源数据验证是确定数据完整性和准确性的合适工具。ECHSA CHSD 十年验证分析显示出高水平的完整性和准确性。ECHSA CHSD 的验证数据非常适合基准测试和研究。
