智能体温单信息系统的实验研究

An experimental study of intelligent temperature system

目的检验智能体温单系统的时间效率和准确度,为进一步提高临床护理自动化水平奠定基础。方法根据病历规范设计智能体温单系统,并设计6名虚拟住院患者连续3d的体温单项目信息。实验室条件下,两年级各10名本科护生分别采用传统手工法(下称手工法)和智能系统法(下称智能法)采集信息并绘制体温单,记录操作时间和出错情况。结果两法所生成的体温单视觉效果差异明显;手工法和智能法绘制体温单绘制总时间,出错、不规范及涂改次数比较,差异有统计学意义(均P<0.01);出错内容包括体温、脉搏、呼吸、血压、大便、物理降温、出入量、文字标记、体温单换页及术后天数记录等;两年级手工法出错率、不规范率及涂改率比较,差异有统计学意义(均P<0.01)。结论智能体温单系统可显著缩短操作时间,有效减少差错,对减轻护理负荷及提高体温单质量具有重要作用。

Objective To examine the time efficiency and accuracy of an intelligent temperature system （ITS）, and to lay foundation for automation of clinical nursing. Methods An ITS was designed in accordance with rules in authoritative regulatory document, and six virtual patients＇ information of body temperature for three consecutive days was created. Twenty nursing undergraduates from two academic levels collected and filled these patients＇ information on standard temperature sheets in a laboratory setting by using the traditional manual approach and the ITS approach. The time spent on documentation and output errors were recorded. Results Significant differences were found between the manual and the ITS approach in respect of performance time, and error counts and obliteration counts （P〈0.01 for all）. The visual effect of the Body temperature sheets produced by the two approaches were impressive. The errors were found in documentation of body temperature, pulse, breath, blood pressure, defecation, physical methods for lowering body temperature, input and output, marking, renewal of temperature sheets, and postsurgical days. As for the manual approach, the error rates in documentation, rates of inappropriate documentation, and rates of obliteration between students from the two academic levels had significant differenees（P〈0.01 for all）. Conclusion The ITS approach to collect data and then to generate temperature sheets is very effective in shortening the performance time and the occurrence of errors. This is of significance for the reduction of nursing workload and for the improvement of quality of temperature sheets.
