Abstract: Objective: The electronic medical record system based on Pediatric Early Warning Score (PEWS) was constructed to form the PEWS assessment-alert-disposal process and analyse its effects. Methods: Relying on the information platform of the hospital, the content and framework of the PEWS-based electronic medical record system was designed. A total of 300 pediatric patients in the hospital were selected and randomly assigned to the manual evaluation group and the electronic medical record system evaluation group, with 150 cases in each group. The time for evaluation, evaluation accuracy and nurses' satisfaction with the two methods were compared between the two groups. Results: The time to have electronic medical record system evaluation (31.18±3.76) s was shorter than that of manual evaluation (55.64±5.01) s. The accuracy rate of electronic medical record system group and manual evaluation group was 100.0% and 82.7% respectively. Meanwhile, the satisfaction rate of nurses using electronic medical record system was 97.8%, which was significantly higher than that of manual evaluation (80.0%). Conclusion: The application of PEWS-based electronic medical record system can improve nurses' work efficiency, accuracy rate of condition evaluation and nurses' satisfaction.
