摘　　要：目的研制儿科静脉维持药物计算的小程序,并测评其可用性。方法于2019年8—12月,采用使用者自建理念研发儿科静脉维持药物计算小程序。于2020年1-2月,采用方便抽样法选取上海儿童医学中心心胸外科重症监护室和病房的10名护士为研究对象。比较两种药物计算方法(基于所研发的小程序的计算方法、基于计算器的传统计算方法)的各200次药物计算所需时间和结果的正确性。采用有用性、满意度、易用性量表(USE)调查10名护士对新技术的接受度,以评价小程序的可用性。结果使用儿科静脉维持药物计算小程序进行药物计算的准确率为100%(200/200),高于使用传统计算方法进行药物计算的88%(176/200),差异有统计学意义(χ^(2)=25.532,P<0.01);使用该小程序进行药物计算所需时间为(15.15±2.74)s,快于使用传统计算方法的(17.09±5.22)s,差异有统计学意义(t=3.451,P=0.001)。10名护士对于小程序的接受度较高,USE平均得分为(6.22±1.03)分。结论本研究所研制的儿科静脉维持药物计算小程序能满足临床护士的使用需求,接受度较高。该程序能以系统计算,有效规避人工计算的差错,节省护士人工计算及双核对的时间,可用性好。Objective To develop a small program for pediatric intravenous maintenance drug calculation and evaluate its usability.Methods The user-built concept was used to develop a small program for pediatric intravenous maintenance drug calculation from August to December 2019.Using the convenient sampling method,a total of 10 nurses in intensive care unit and ward of Department of Cardiothoracic Surgery of Shanghai Children's Medical Center from January to February 2020 were selected as the research objects.The time required for drug calculation and correctness of results were compared for each of two methods(calculation method based on the developed small program and the traditional method based on the calculator)for 200 times.Usefulness,Satisfaction,and Ease of Use(USE)was used to investigate the acceptability of 10 nurses to the new technology to evaluate usability of the small program.Results The accuracy rate of medicine calculation using the pediatric intravenous maintenance drug calculation small program was 100%(200/200),which was higher than 88%(176/200)using traditional calculation methods for medicine calculation,and the difference was statistically significant(χ^(2)=25.532,P<0.01).The time required for drug calculation using the small program was(15.15±2.74)s,which was faster than(17.09±5.22)s using the traditional calculation method,and the difference was statistically significant(t=3.451,P=0.001).The 10 nurses had a high acceptance of the small program and the average score of USE was(6.22±1.03).Conclusions The pediatric intravenous maintenance drug calculation program developed in this research can meet the needs of clinical nurses and has a relatively high acceptance.The program can be calculated by the system,effectively avoid the error of manual calculation and save time of manual calculation and double check by nurses,which has good usability.
