Health information exchange system usage patterns in three communities: Practice sites, users, patients, and data
Electronic Health Records
Health Information Systems
Medical Record Linkage
This study is among the first to illustrate large-scale usage of a query-based HIE system implemented across multiple communities. Patient summary data displayed by default may be an important feature of query-based HIE systems. User role, practice site type, and patient consent workflow may affect patterns of query-based HIE web portal system usage in the communities studied and elsewhere.
