Electronic health record (EHR) system customers that can access their data have found that they also need information about the database structure used by the EHR technology developer in order to effectively use the data for custom reports or to even understand the customer’s own patient population and the unit costs of care.

Some EHR technology developers are reportedly unwilling to provide data models or “data dictionaries” or are charging significant fees for information that helps the customer understand how the data is held in the EHR and may be efficiently extracted and used for other purposes.
