摘要

背景:肿瘤的准确记录为推进癌症研究和改善患者护理提供了重要的机会,但它也对医疗保健管理提出了挑战。目的:本研究旨在评估源数据验证(SDV)在提高肿瘤文献数据质量方面的有效性和资源意义,重点关注准确性、完整性和正确性。方法:使用来自德国一家大型大学医院的肿瘤文件数据,由外部审计组(RE组)进行SDV,将该中心肿瘤文件学家(TD组)最初记录的数据与2016-2020年的可用源文件进行比较。分析集包括240例病例,具有跨各种器官实体和其他肿瘤特征战略性选择的示例数据字段。鉴定出的错误由第三组(CO组)进行交叉验证。结果:可视化显示了诊断年份和器官实体的错误频率。潜在的错误被识别出来,并向肿瘤文档单位提供反馈。然而,错误识别的不确定性引发了对SDV有效性的质疑。结论:虽然SDV在识别错误方面是有效的,但由于源数据不明确和外部审计师的潜在偏见,以及被认为不经济,SDV面临着挑战。该研究表明sdv适用于小样本验证,但质疑其在大数据集上的可扩展性。对健康信息管理的影响:建议使用其他方法,例如子系统的数据交换接口或合理性检查,以提高数据质量。这项研究强调需要探索替代方案,以提高肿瘤文件的数据质量。

Is source data verification a valid tool to improve data quality of tumour documentation data? A critical assessment.

Background: Accurate documentation of tumours presents significant opportunities for advancing cancer research and improving patient care, yet it also poses challenges for healthcare management.

Objective: This study aimed to assess the effectiveness and resource implications of source data verification (SDV) in enhancing the quality of tumour documentation data, focusing on accuracy, completeness and correctness.

Method: Using tumour documentation data from a large German University Hospital, an SDV was conducted by an external audit group (group RE), comparing the data initially documented by the centre's tumour documentalists (group TD) to available source documents for the years 2016-2020. The analysis set comprised 240 cases, with exemplary data fields strategically selected across various organ entities and other tumour features. Identified errors were cross-validated by a third group (group CO).

Results: Visualisations depicted error frequencies by diagnosis year and organ entity. Potential errors were identified, providing feedback to the tumour documentation unit. However, uncertainties in error identification raised questions about the efficacy of SDV.

Conclusion: While effective in identifying errors, SDV faced challenges due to ambiguous source data and potential bias from external auditors, as well as being deemed uneconomical. The study suggests SDVs suitability for small sample validation but questions its scalability for large datasets.Implications for health information management:Alternative methods, such as data exchange interfaces to subsystems or plausibility checks, are recommended for enhancing data quality. This study emphasises the need to explore alternatives for improving data quality in tumour documentation.
