Clinical databases are increasingly being employed to evaluate the quality of treatments, including patients with peripheral vascular disease. Valid data is vital to the value of these analyses.
To assess the validity of clinical data in a population-based national vascular registry.
Traditional reproducibility study was supplemented by refilling of data by an independent observer, thereby creating three data sets for comparison.
Twenty prospectively recorded electronic forms from each department were selected randomly from the Danish National Vascular Registry. Data forms were refilled by the surgeons of the department concerned, and by an independent member of the board of the Danish National Vascular Registry. Refilling was performed blinded to the original forms.
A high degree of accuracy of clinical data can be achieved. An independent observer makes it possible to evaluate the classification of observer dependent parameters and explain differences in the reproducibility of data.
临床数据库越来越多地用于评估治疗质量，包括外周血管疾病患者。有效数据对于这些分析的价值至关重要。
评估基于人群的国家血管登记处临床数据的有效性。
传统的可重复性研究通过由独立观察员重新填写数据得到补充，从而创建三个数据集进行比较。
从丹麦国家血管登记处随机选择每个科室的20份前瞻性记录的电子表格。数据表格由相关科室的外科医生以及丹麦国家血管登记处董事会的一名独立成员重新填写。重新填写时对原始表格保密。
可以实现临床数据的高度准确性。独立观察员能够评估依赖于观察者的参数的分类，并解释数据可重复性方面的差异。
