AIM
To assess the effect of the use of bar code readers and programmable keypads for entry of specimen details and results in two microbiology laboratories.
METHODS
The solutions selected in each laboratory are described. The benefits resulting from the implementation were measured in two ways. The speed of data entry and error reduction were measured by observation. A questionnaire was completed by users of bar codes.
RESULTS
There were savings in time and in reduced data entry errors. Average time to enter a report by keyboard was 21.1 s v 14.1 s for bar coded results entry. There were no observed errors with the bar code readers but 55 errors with keystroke entries. The laboratory staff of all grades found the system fast, easy to use, and less stressful than conventional keyboard entry.
CONCLUSIONS
Indirect time savings should accrue from the observed reduction in incorrectly entered data. Any microbiology laboratory seeking to improve the accuracy and efficiency of data entry into their laboratory information systems should consider the adoption of this technology which can be readily interfaced to existing terminals.
目的
评估在两个微生物实验室中使用条形码阅读器和可编程键盘输入标本详细信息及结果的效果。
方法
描述了每个实验室选择的解决方案。通过两种方式衡量实施带来的益处。通过观察测量数据录入速度和错误减少情况。条形码使用者填写了一份问卷。
结果
节省了时间，减少了数据录入错误。通过键盘录入一份报告的平均时间为21.1秒，而条形码结果录入为14.1秒。条形码阅读器未观察到错误，但按键录入有55个错误。各级实验室工作人员都认为该系统速度快、易于使用，且比传统键盘录入压力小。
结论
从观察到的错误录入数据减少情况来看，应能间接节省时间。任何寻求提高实验室信息系统数据录入准确性和效率的微生物实验室都应考虑采用这种可轻松连接到现有终端的技术。
