Abstract

Background: The International Statistical Classification of Diseases and Related Health Problems (ICD) codes play a critical role as fundamental data for hospital management and can significantly impact diagnosis-related groups (DRGs). This study investigated the quality issues associated with ICD data and their impact on improper DRG payments.

Methods: Our study analyzed data from a Chinese hospital from 2016-2017 to evaluate the impact of ICD data quality on Chinese Diagnosis-related Group (CN-DRG) evaluation variables and payments. We assessed different stages of the ICD generation process and established a standardized process for evaluating ICD data quality and relevant indicators. The validation of the data quality assessment (DQA) was confirmed through sampling data.

Results: This study of 85,522 inpatient charts found that gynecology had the highest and obstetrics had the lowest diagnosis agreement rates. Pediatrics had the highest agreement rates for MDC and DRG, while neonatal pediatrics had the lowest. The Case Mix Index (CMI) of Coder-coded data showed to be more reasonable than physician-coded data, with increased DRG payments in obstetrics and gynecology. The DQA model revealed coding errors ranging from 40.3 percent to 65.1 percent for physician and 12.2 percent to 23.6 percent for coder. Payment discrepancies were observed, with physicians resulting in underpayment and coders displaying overpayment in some cases.

Conclusion: ICD data is crucial for effective healthcare management, and implementing standardized and automated processes to assess ICD data quality can improve data accuracy. This enhances the ability to make reasonable DRG payments and accurately reflects the quality of healthcare management.

评估ICD数据质量及其对DRG支付的影响:来自中国某妇幼专科医院的证据
背景:国际疾病及相关健康问题统计分类(ICD)代码作为医院管理的基础数据起着至关重要的作用,可以显著影响诊断相关组(drg)。本研究调查了与ICD数据相关的质量问题及其对不当DRG支付的影响。方法:本研究分析了2016-2017年一家中国医院的数据,以评估ICD数据质量对中国诊断相关组(CN-DRG)评估变量和支付的影响。我们评估了ICD生成过程的不同阶段,并建立了评估ICD数据质量和相关指标的标准化流程。通过抽样数据验证了数据质量评价(DQA)的有效性。结果:通过对85,522份住院病历的研究发现,诊断符合率最高的是妇科,最低的是产科。儿科对MDC和DRG的一致性率最高,而新生儿儿科的一致性率最低。编码数据的病例混合指数(CMI)显示比医生编码数据更合理,产科和妇科的DRG支付增加。DQA模型显示,医生的编码错误率为40.3%至65.1%,编码人员的编码错误率为12.2%至23.6%。观察到支付差异,在某些情况下,医生导致支付不足,编码人员显示支付过多。结论:ICD数据对于有效的医疗管理至关重要,实施标准化和自动化流程来评估ICD数据质量可以提高数据准确性。这增强了进行合理DRG支付的能力,并准确反映了医疗保健管理的质量。
