We have been working to develop a statewide injury surveillance system using not only hospital-based trauma registries but also other sources of data (including ambulance run reports, hospital discharge abstracts, and death certificates). For this purpose, a commercially available probabilistic matching program was compared to the deterministic program described previously. Using the same data preprocessing and linkage strategy, we programmed the probabilistic software to perform the matching step and compared the results with those obtained from the previously tested program. The outcomes using our data were similar, but we expect the probabilistic program to be more adaptable for general use, especially if large amounts of data must be linked.
我们一直在努力开发一个全州范围的伤害监测系统,不仅使用基于医院的创伤登记系统,还使用其他数据来源(包括救护车出车报告、医院出院摘要和死亡证明)。为此,我们将一个商业可用的概率匹配程序与之前描述的确定性程序进行了比较。使用相同的数据预处理和链接策略,我们对概率软件进行编程以执行匹配步骤,并将结果与之前测试程序获得的结果进行比较。使用我们的数据得到的结果相似,但我们预计概率程序更适用于一般用途,特别是在必须链接大量数据的情况下。
