儿童早期预警评分电子病历系统的设计与应用效果评价

目的:设计儿童早期预警评分(Pediatric Early Warning Score,PEWS)电子病历系统信息化平台,形成PEWS评估-提醒-处置流程,并分析其应用效果。方法:依托医院信息化平台,设计PEWS电子病历系统内容与架构。选取符合纳入标准的住院患儿300例,将患儿随机分配至人工评估组(n=150)和电子病历系统评估组(n=150),比较两组评估耗时和准确率以及护士对两种评估方法的满意度。结果:采用电子病历系统耗时短于人工评估方法(31.18±3.76)s vs(55.64±5.01)s];电子病历系统评估正确率高于人工评估组(100.0%vs 82.7%);护士使用电子病历系统评估满意度高于使用人工评估(97.8%vs 80.0%)。结论:PEWS电子病历系统评估的应用可提高护士的工作效率、病情评估的准确率以及护士的满意度。

Development and evaluation of application effect of electronic medical record system based on Pediatric Early Warning Score

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.
