A pragmatic method for electronic medical record-based observational studies: developing an electronic medical records retrieval system for clinical research.

ABSTRACT:

Objective

The use of electronic medical record (EMR) data is necessary to improve clinical research efficiency. However, it is not easy to identify patients who meet research eligibility criteria and collect the necessary information from EMRs because the data collection process must integrate various techniques, including the development of a data warehouse and translation of eligibility criteria into computable criteria. This research aimed to demonstrate an electronic medical records retrieval system (ERS) and an example of a hospital-based cohort study that identified both patients and exposure with an ERS. We also evaluated the feasibility and usefulness of the method.

Design

The system was developed and evaluated.

Participants

In total, 800 000 cases of clinical
