The report of the CUSUM across surgical and interventional procedures has spawned a fair confusion in the literature.
To assess the use of the CUSUM and to clarify its utilisation in the perspective of future studies. Nature of the study: Retrospective review.
A systematic literature search of Medline was carried out. From each article, data regarding the design of the study, the specialty, the performance criterion, the unit under control, the methodology and the model of the CUSUM used, the use of a graph, the use of a test and the type of test applied were retrieved.
31 studies were found relevant. The design was mainly retrospective for the analysis of the learning curve. The main performance criteria under control were morbidity, mortality and success of the procedure. A graph was plotted in all studies as a CUSUM plot or as cumulative sums of non-negative values. A test was used in 17 studies. Mislabelling of the plot and the test, and misuse of control limits were the most commonly reported mistakes.
The CUSUM tool is not yet properly reported in the surgical literature. Therefore, reporting of the CUSUM should be clarified and standardised before its use widens.
关于外科手术和介入手术的累积和（CUSUM）报告在文献中引发了相当大的混乱。
评估CUSUM的使用情况，并从未来研究的角度阐明其应用。研究性质：回顾性研究。
对Medline进行系统的文献检索。从每篇文章中检索有关研究设计、专业、性能标准、受控单元、CUSUM使用的方法和模型、图表的使用、检验的使用以及所应用检验类型的数据。
发现31项研究相关。该设计主要为回顾性，用于分析学习曲线。受控的主要性能标准是发病率、死亡率和手术成功率。所有研究中均绘制了图表，作为CUSUM图或非负值的累积和。17项研究使用了检验。图表和检验的错误标注以及控制限的误用是最常报告的错误。
外科文献中对CUSUM工具的报告尚不恰当。因此，在其使用范围扩大之前，应明确并规范CUSUM的报告。
