The cost difference of administering cimetidine 300 mg via intravenous piggyback (IVPB) every six hours by a conventional separate container system versus using an automated intermittent i.v. administration system was evaluated. The study was conducted in two phases. Phase 1 documented the amount of drug waste with the two systems, and phase 2 examined the practical use of the IVAC Multi Dose System. Nurses who administered the medication using the multiple-dose system completed a questionnaire on its operation. A materials cost analysis was performed to compare the two methods. The two systems were found to have approximately equivalent amounts of drug waste over the 30-day evaluation period of phase 1. The mean percentage of doses wasted was 12.2% with the conventional single-dose minibag method and 12.7% with the automated multiple-dose method. The multiple-dose system had a lower cost per dose of cimetidine ($2.25 versus $3.47). These savings appear to outweigh the cost of the additional equipment necessary for the automated system. The majority of nurses preferred the multiple-dose system. Potential problems encountered in accurately delivering doses with the multiple-dose automated system were identified, and possible solutions are suggested. The use of an automated multiple-dose i.v. administration system can potentially decrease the materials cost portion of drug administration. The total impact on hospital costs needs to be evaluated, and other comparisons with alternative administration systems need to be performed.
评估了通过传统的单独容器系统每六小时静脉滴注300毫克西咪替丁与使用自动间歇性静脉给药系统的成本差异。该研究分两个阶段进行。第一阶段记录了两种系统的药物浪费量，第二阶段检查了IVAC多剂量系统的实际使用情况。使用多剂量系统给药的护士完成了一份关于其操作的问卷。进行了材料成本分析以比较这两种方法。在第一阶段的30天评估期内，发现两种系统的药物浪费量大致相当。传统单剂量小药袋法的平均浪费剂量百分比为12.2%，自动多剂量法为12.7%。多剂量系统每剂西咪替丁的成本较低（2.25美元对3.47美元）。这些节省似乎超过了自动化系统所需额外设备的成本。大多数护士更喜欢多剂量系统。确定了在使用多剂量自动化系统准确给药时遇到的潜在问题，并提出了可能的解决方案。使用自动多剂量静脉给药系统可能会降低给药的材料成本部分。需要评估对医院成本的总体影响，并且需要与其他替代给药系统进行其他比较。
