“The number of standard setting organizations (SSOs) from which specifications have been drawn to create Electronic Health Records (EHRs) are legion, due to the complex nature of these goal. Some of the standards utilized are generic, and common to any sophisticated Internet-enabled commercial system. Others are specific to science, but usable generally in paper as well as information technology (IT) based health care systems.

One of the oldest and most important is Health Level 7, more commonly referred to as HL7.”
