OBJECTIVES
The objectives of this study are to analyze the variation of the surgical time and of disposable costs per surgical procedure and to analyze the association between disposable costs and the surgical time.
METHODS
The registration of data was done in an operating room of a 419 bed general hospital, over a period of three months (n = 1556 surgical procedures). Disposable material per procedure used was recorded through a barcode scanning method.
RESULTS
The average cost (standard deviation) of disposable material is €183.66 (€183.44). The mean surgical time (standard deviation) is 96 min (63). Results have shown that the homogeneity of operating time and DM costs was quite good per surgical procedure. The correlation between the surgical time and DM costs is not high (r = 0.65).
CONCLUSIONS
In a context of Diagnosis Related Group (DRG) based hospital payment, it is important that costs information systems are able to precisely calculate costs per case. Our results show that the correlation between surgical time and costs of disposable materials is not good. Therefore, empirical data or itemized lists should be used instead of surgical time as a cost driver for the allocation of costs of disposable materials to patients.
目的
本研究的目的是分析每次手术的手术时间变化和一次性成本，并分析一次性成本与手术时间之间的关联。
方法
在一家拥有419张床位的综合医院的手术室进行为期三个月的数据登记（n = 1556例手术）。通过条形码扫描方法记录每次手术使用的一次性材料。
结果
一次性材料的平均成本（标准差）为183.66欧元（183.44欧元）。平均手术时间（标准差）为96分钟（63分钟）。结果表明，每次手术的手术时间和一次性材料成本的同质性相当好。手术时间与一次性材料成本之间的相关性不高（r = 0.65）。
结论
在基于诊断相关组（DRG）的医院付费背景下，成本信息系统能够精确计算每个病例的成本非常重要。我们的结果表明，手术时间与一次性材料成本之间的相关性不佳。因此，应使用经验数据或明细清单，而非手术时间，作为将一次性材料成本分摊给患者的成本驱动因素。
