Development and application of the key information technique related to safety of intravenous doses in pediatric patients

目的:分析儿童静脉药物剂量安全相关的关键信息技术在提升儿童静脉给药安全水平方面的可行性。方法 :研发儿童静脉药物剂量安全相关的关键信息技术。采用方便抽样,选取某三级甲等专科医院的30名护士,分别使用新技术和传统方法各进行150次儿童静脉给药剂量提取、剂量计算、剂量设置,比较两种方法所得结果的正确性。此外,采用有用性、满意度、易用性(Usefulness,Satisfaction and Ease of use,USE)量表测评新技术的可用性,使用美国国家航天航空局任务负荷指数(National Aeronautics and Space Administration Task Load Index,NASA-TLX)测评护士的认知负荷。结果 :在儿童静脉给药剂量提取、剂量计算、剂量设置环节,传统方法的正确率分别为94.0%、88.7%、96.0%,实施新技术的正确率均为100.0%,差异均有统计学意义(P<0.05);护士关于新技术的USE量表得分为(6.30±0.55)分;新技术方法的NASA-TLX得分为(31.94±7.87)分,传统方法的得分为(45.39±15.42)分,差异有统计学意义(P<0.05)。结论 :本研究所研发的儿童静脉药物剂量安全相关的关键信息技术能提升护士药物剂量问题解决能力,且系统的可用性较好,护士的认知负荷低,有助于提升儿童静脉给药安全水平。

Objective: To analyze the feasibility of the key information technique related to the safety of intravenous doses in pediatric patients to enhance safe administration of intravenous doses in children. Methods: The key information technique related to safe administration of intravenous drugs in children was developed. Convenience sampling was then used to include 30 nurses in a tertiary grade A hospital to offer 150 intravenous administration(dose extraction, dose calculation,dose setting) utilizing the new technique method and the traditional method, respectively to compare their accuracy. The usability of the new technique was evaluated by the Usefulness, Satisfaction, and Ease of Use Questionnaire(USE), and the cognitive load of nurses was evaluated by the National Aeronautics and Space Administration Task Load Index(NASATLX). Results: The accuracy of dose extraction, dose calculation and dose setting of the traditional method was 94.0%,88.7%, 96.0%, respectively, while the accuracy of this new technique was 100.0% with the difference being statistically significant(P<0.05). The score of the USE questionnaire was(6.30±0.55) points in new technique method;Compared with the traditional method(45.39±15.42), the new technique method(31.94±7.87) scored lower on the NASA-TLX questionnaire(P<0.05). Conclusion: The application of the key information technique related to safe intravenous doses in pediatric patients can improve nurses’ competence in dealing with dosage calculation. Moreover, the system developed in this study show good usability and cause less cognitive load for nurses, which is conducive to the safety of intravenous administration in children.
