Based on the relevant literature of quality assessment and data error reports of clinical data application, the existing assessment knowledge is decomposed, combined and summarized to construct the clinical data assessment indicators that uniquely expressed the clinical assessment problems, and the assessment methods applicable to each indicator are expounded. By comparing with previous studies and verify with relevant national standards, the results show that the indicators proposed in this study can more clearly and accurately correspond to the actual needs, which is conducive to promoting the standardization of clinical data quality assessment.
