Efforts to utilize Uniform Hospital Discharge Data Sets (UHDDS) for epidemiological studies have been hampered by the limitations of those databases. The purpose of this paper is to illustrate that linking to external databases can provide the verification necessary to overcome many of those limitations. This method has dramatically altered study design at the Connecticut Hospital Research and Education Foundation and has provided an efficient method for specifying data collection weaknesses within the resident databases.
利用统一医院出院数据集（UHDDS）进行流行病学研究的工作一直受到这些数据库局限性的阻碍。本文旨在说明，与外部数据库建立链接可以提供克服其中许多局限性所需的验证。这种方法极大地改变了康涅狄格医院研究与教育基金会的研究设计，并为确定住院医师数据库中的数据收集弱点提供了一种有效方法。
