The effects of implementing a bar-code system for issuing medical supplies to nursing units at a university teaching hospital were evaluated. Data on the time required to issue medical supplies to three nursing units at a 480-bed, tertiary-care teaching hospital were collected (1) before the bar-code system was implemented (i.e., when the manual system was in use), (2) one month after implementation, and (3) four months after implementation. At the same times, the accuracy of the central supply perpetual inventory was monitored using 15 selected items. One-way analysis of variance tests were done to determine any significant differences between the bar-code and manual systems. Using the bar-code system took longer than using the manual system because of a significant difference in the time required for order entry into the computer. Multiple-use requirements of the central supply computer system made entering bar-code data a much slower process. There was, however, a significant improvement in the accuracy of the perpetual inventory. Using the bar-code system for issuing medical supplies to the nursing units takes longer than using the manual system. However, the accuracy of the perpetual inventory was significantly improved with the implementation of the bar-code system.
对某大学教学医院实施向护理单元发放医疗用品的条形码系统的效果进行了评估。收集了一家拥有480张床位的三级护理教学医院向三个护理单元发放医疗用品所需时间的数据：（1）在实施条形码系统之前（即使用手工系统时），（2）实施后一个月，以及（3）实施后四个月。同时，使用15种选定物品监测中央供应永续盘存的准确性。进行单因素方差分析以确定条形码系统和手工系统之间是否存在显著差异。由于将订单输入计算机所需时间存在显著差异，使用条形码系统比使用手工系统花费的时间更长。中央供应计算机系统的多次使用要求使得输入条形码数据的过程要慢得多。然而，永续盘存的准确性有了显著提高。使用条形码系统向护理单元发放医疗用品比使用手工系统花费的时间更长。然而，随着条形码系统的实施，永续盘存的准确性得到了显著提高。
