Identifying Clinical/Translational Research Cohorts: Ascertainment via Querying an Integrated Multi-Source Database

submitted by: Jamia
Abstract: BACKGROUND: Ascertainment of potential subjects has been a longstanding problem in clinical research. Various methods have been proposed, including using data in electronic health records. However, these methods typically suffer from scaling effects-some methods work well for large cohorts; others work for small cohorts only. OBJECTIVE: We propose a method that provides a simple identification of pre-research cohorts and relies on data available in most states in the USA: merged...
