A sample frame is the listing of the units from which a sample is to be selected. When deciding upon a file to serve as a source for a sample frame for a survey, perhaps the most important consideration is the extent to which the target population will be covered by the frame. However, other issues also come into play such as the accuracy of contact and other information appearing on the file as well as its cost. The American Medical Association Masterfile has long been considered the preferred choice for surveys of physicians, although it does have drawbacks. Here we consider two alternative files, discussing their relative advantages and disadvantages. For surveys of physician practices (or other organizations that employ physicians), there have been no files that are obvious choices to serve as the basis for a sample frame. Here we discuss data collection on physician practices from an analytic perspective and consider how sampling physicians to obtain practice level data may be a desirable approach.
抽样框是要从中选择样本的单位列表。在决定用作调查抽样框来源的文件时,也许最重要的考虑因素是抽样框涵盖目标人群的程度。但是,其他问题也会产生影响,例如文件上的联系人和其他信息的准确性以及其成本。美国医学协会主文件长期以来一直被认为是医生调查的首选选择,尽管它确实有一些缺点。在这里,我们考虑了另外两个替代文件,讨论了它们的相对优缺点。对于医生实践(或雇用医生的其他组织)的调查,没有任何文件是作为抽样框基础的明显选择。在这里,我们从分析的角度讨论医生实践的数据收集,并考虑如何抽样医生以获取实践水平数据可能是一种理想的方法。
