Achieving sample size is imperative to obtaining sufficient power to detect potential effects in health care research, yet many research studies are prone to under-recruitment. Not only does this create problems with power but also it contributes to research extensions, additional costs and delayed results. To combat this problem, one increasingly used technique is database recruitment, a method of searching the electronic medical records system for potential research participants.
We discuss the advantages and disadvantages of identifying potential research participants using database recruitment with particular reference to primary care.
Database recruitment is a relatively simple and affordable means to recruit large numbers of patients in a timely manner; however, it is not without limitations.
在医疗保健研究中，要获得足够的效力来检测潜在影响，实现样本量是至关重要的，但许多研究都容易出现招募不足的情况。这不仅会导致效力问题，还会导致研究延期、额外成本和延迟结果。为了解决这个问题，一种越来越常用的技术是数据库招募，这是一种在电子病历系统中搜索潜在研究参与者的方法。
我们讨论了使用数据库招募来确定潜在研究参与者的优缺点，特别是在初级保健方面。
数据库招募是一种相对简单且经济实惠的方法，可以及时招募大量患者；但是，它并非没有局限性。
