Abraxane® and Taxol® are both effective drugs for the treatment of advanced stage breast cancer. However, each agent possesses unique drug delivery characteristics with the former not requiring premedication and having a considerably shorter recommended infusion time (i.e. 30 min vs. 2-4 h). To measure the overall efficiency and cost-saving potential associated with Abraxane® relative to Taxol®, a time and motion study was undertaken in breast cancer patients treated in China.
Baseline patient data collection included age, disease stage, number and sites of metastatic disease, and performance status. Time and resource use data were then collected from breast patients being treated with Abraxane® (n = 12) or Taxol® (n = 15) in one of three cancer clinics located in Jiangsu, Shanghai, and Beijing. Resource use and time impact on clinical staff were quantified using unit cost estimates. This included costs for drug preparation, administration, materials and supplies, premedication, patient chair time, labor costs, and all acute adverse drug reactions. Outcomes were presented as a mean total time and cost for delivering a dose of Abraxane® or Taxol® and were compared using parametric and non-parametric statistical tests where appropriate. All costs were reported in US dollars (US$1 = 6.1 RMB, as of January 2014).
Patients were comparable with respect to mean age, number of metastatic sites, and performance status. Approximately 9 of 12 (75%) patients received Abraxane® as on a weekly schedule (vs. every 3 weeks) compared to 6 of 15 (40%) with Taxol®. There were 5 (33.3%) acute adverse drug reactions with Taxol®, 3 of which required a physician visit and the initiation of supportive interventions. In contrast, there was only one minor event with Abraxane® (8.3%), which was easily managed with a temporary stoppage of the infusion. From the time and motion study, the mean total time for Abraxane® and Taxol® delivery (preparation, administration, premedication, total chair time, and adverse effects management) was 84 and 282 min respectively (p < 0.001), with the associated costs being US$59 and US$254 respectively per dose (p < 0.001).
To our knowledge, this is first such study in breast cancer patients to be undertaken in China. Abraxane® was associated with fewer acute adverse drug reactions and significant reductions in health care resources, physician/nurse time and overall drug delivery costs compared to Taxol®.
艾日布林(Abraxane®)和紫杉醇(Taxol®)都是治疗晚期乳腺癌的有效药物。然而,每种药物具有独特的给药特性,前者无需预处理且推荐输注时间明显更短(即30分钟对比2 - 4小时)。为衡量艾日布林相对于紫杉醇的总体效率和成本节约潜力,在中国接受治疗的乳腺癌患者中进行了一项时间与动作研究。
基线患者数据收集包括年龄、疾病分期、转移病灶数量和部位以及体能状态。然后从位于江苏、上海和北京的三家癌症诊所之一接受艾日布林治疗(n = 12)或紫杉醇治疗(n = 15)的乳腺癌患者中收集时间和资源使用数据。使用单位成本估算来量化资源使用和时间对临床工作人员的影响。这包括药物制备、给药、材料和用品、预处理、患者候诊时间、劳动力成本以及所有急性药物不良反应的成本。结果以给予一剂艾日布林或紫杉醇的平均总时间和成本呈现,并在适当情况下使用参数和非参数统计检验进行比较。所有成本均以美元报告(截至2014年1月,1美元 = 6.1元人民币)。
患者在平均年龄、转移部位数量和体能状态方面具有可比性。12名患者中有约9名(75%)按每周给药方案接受艾日布林治疗(对比每3周一次),而15名接受紫杉醇治疗的患者中有6名(40%)。紫杉醇治疗出现5例(33.3%)急性药物不良反应,其中3例需要医生诊治并启动支持性干预措施。相比之下,艾日布林仅出现1例轻微事件(8.3%),通过暂时停止输注即可轻松处理。根据时间与动作研究,给予艾日布林和紫杉醇的平均总时间(制备、给药、预处理、总候诊时间和不良反应管理)分别为84分钟和282分钟(p < 0.001),每剂相关成本分别为59美元和254美元(p < 0.001)。
据我们所知,这是在中国乳腺癌患者中开展的首例此类研究。与紫杉醇相比,艾日布林的急性药物不良反应较少,医疗资源、医生/护士时间和总体给药成本显著降低。
