The effect of a bar-code system on personnel time requirements and data-entry accuracy in an existing automated controlled substances inventory system was determined. In the previous system, technicians used a keyboard and alphanumeric codes to enter into the computer data about the physical transfer of controlled substances among hospital areas. A system for barcode data entry was adapted for use with the existing procedure. After learning to use the bar-code system, four experienced technicians entered data by the keyboard method for eight days and the bar-code method for eight days during a 32-day study period. The amount of time required to enter all transactions and the accuracy of data entry were measured. Mean data-entry times for the keyboard and bar-code methods were not significantly different, most likely because of the greater number of manipulations needed for bar-code data entry. The mean percentage error associated with the bar-code method (0.79%) was significantly less than the error associated with the keyboard method (1.53%). For this particular computer system in which bar-code data entry was adapted to existing procedures, use of bar codes to enter controlled substances inventory data was not substantially faster but was more accurate than a traditional key-board data-entry method.
我们确定了条形码系统对现有自动化管制药品库存系统中人员时间需求和数据录入准确性的影响。在之前的系统中，技术人员使用键盘和字母数字代码将管制药品在医院各区域间物理转移的数据输入计算机。一种条形码数据录入系统被适配用于现有程序。在一个为期32天的研究期间，四名经验丰富的技术人员在学会使用条形码系统后，先用键盘方法录入数据八天，再用条形码方法录入数据八天。测量了录入所有交易所需的时间以及数据录入的准确性。键盘录入法和条形码录入法的平均数据录入时间没有显著差异，很可能是因为条形码数据录入需要更多操作。与条形码方法相关的平均百分比误差（0.79%）显著低于与键盘方法相关的误差（1.53%）。对于这种将条形码数据录入适配于现有程序的特定计算机系统，使用条形码录入管制药品库存数据的速度并没有大幅加快，但比传统的键盘数据录入方法更准确。
