This study prospectively quantified wastage of cancer chemotherapeutic drugs in an oncology unit to find the associated cost in 3 months. Retrospective analysis of drug usage for 12 months was also conducted to determine the expected drug loss in 1 year. The effect of vial sharing was evaluated under the assumption of sharing. A significant drug wastage of 19.72% (95% confidence interval [CI], 14.52-24.93%) in 3 months and 17.14% (95% CI 14.69-19.59%) in 1 year occurred in our oncology unit. Number of vials purchased (r = 0.362, p < 0.01), weight (r = -0.146, P < .01) and body surface area (r = -0.26, P < .01) correlated with the drug wasted. Vial sharing assumption showed a 9% (95% CI, 2.5-15.5%) reduction in cost in 1 year.
本研究前瞻性地量化了肿瘤科中癌症化疗药物的浪费情况,以在 3 个月内发现相关成本。还对 12 个月的药物使用情况进行了回顾性分析,以确定 1 年内预计的药物损失。在假设共享的情况下,评估了小瓶共享的效果。我们肿瘤科在 3 个月和 1 年内分别发生了 19.72%(95%置信区间 [CI],14.52-24.93%)和 17.14%(95% CI 14.69-19.59%)的显著药物浪费。购买的小瓶数量(r=0.362,p<0.01)、重量(r=-0.146,P<.01)和体表面积(r=-0.26,P<.01)与浪费的药物相关。小瓶共享假设表明,1 年内成本降低了 9%(95%CI,2.5-15.5%)。
