Abstract：Objective To explore the effect of text extraction and quality defect analysis of electronic medical record based on neural
network model. Methods A total of 90000 electronic medical records filed in our hospital from January 1, 2020 to October 31, 2021 were
selected, including 70000 outpatient medical records and 20000 inpatient medical records. Diagnosis related groups (DRGs) system
was used to group medical records, statistical extraction and quality defects. Natural language was used to extract clinical useful
information, and text convolutional neural network (TextCNN) was used to build quality defect classification model. Results Among
the 90000 electronic medical records included in the study, 16685 electronic medical records had quality defects, and the incidence
of quality defects was 18.54%. After manual reexamination, the problems of medical records with quality defects mainly include
incomplete records of changes in the condition and doctor’s orders, incomplete filling of inspection reports, etc. The accuracy,
sensitivity, specificity, positive and negative predictive values of TextCNN model were higher than those of manual review (P<0.05).
After the analysis of TextCNN model, the incidence of problem cases screened by DRGs decreased significantly (χ2=16.830, P<0.05).
Conclusion The neural network model has a good effect on the text extraction and quality defect screening of electronic medical
record, and can be used in clinical promotion to improve the quality of medical record.
