This study evaluated the feasibility of using published data from more than one register to define the performance of different hip implants. In order to obtain estimates of performance for specific types of hip system from different register, we analysed data from the annual reports of five national and one Italian regional register. We extracted the number of implants and rates of implant survival at different periods of follow-up. Our aim was to assess whether estimates of cumulative survival rate were comparable with data from registers from different countries, and our conclusion was that such a comparison could only be performed incompletely.
本研究评估了使用来自多个登记处的已发表数据来定义不同髋关节植入物性能的可行性。为了从不同登记处获得特定类型髋关节系统的性能估计值，我们分析了五个国家登记处和一个意大利地区登记处年度报告中的数据。我们提取了植入物数量以及不同随访期的植入物存活率。我们的目的是评估累积存活率的估计值是否与来自不同国家登记处的数据具有可比性，而我们的结论是这种比较只能不完全进行。
