HL7 is the defacto standard for health care inter-system messaging. It is a multi-delimited format, starting with pipe-delimited lines of data, which are then subdivided by other delimiter characters (see example below). It is used by hospitals to allow different systems to communicate with each other, including the Admission/Discharge/Transfer (ADT), Laboratory systems, Medication/Prescription systems and the like. Multiple HL7 interfaces such as those just mentioned were the primary sources of data for our application, CDR-Web, and are the messages shared in our ADT Notification System and our Lab Reporting System.
