Health Level 7 (HL7) Data

**Note: As of September 2015, the HL7 daily data feeds in the EpiData Center also include the EDIPN/DODID variable. At this time, the technical documents below do not reflect the change. **

List of SOPs for Projects/Tasks Using HL7 Data in the EDC: Document contains a list of active and pending SOP that utilize in full or in part HL7 data (chemistry, microbiology, pathology, and/or pharmacy) for completion of projects/tasks. This is a live document and edits will be provided as SOPs are added or edited. If you have any questions on existing projects/tasks that we may be able to support you on, please contact us.

Abstract: The EpiData Center Department (EDC) at the Navy and Marine Corps Public Health Center evaluated the Health Level 7 (HL7) data source for its usefulness in health surveillance activities. This technical document provides a history of the HL7 pharmacy intravenous database and its contents, explains the creation of prescription records, describes the pathway of data from healthcare provider to the EDC, provides a detailed descriptions of all variables within the database, and assesses the database's strengths and limitations. Given an understanding of the strengths and limitations of the data, HL7 pharmacy intravenous data have proven to be a valuable source of health information for surveillance purposes. The data can be used for case identification when disease-specific treatment is available, or used to assess clinical practice guideline adherence for known cases. Furthermore, data are received in a timely fashion, allowing for near-real-time surveillance of diseases.

Background: Medical surveillance in the military can be improved through the use of clinical laboratory results collected within the Military Health System (MHS). This presentation describes an effort to establish Electronic Laboratory Reporting (ELR) in the military using existing HL7 messages. HL7 data is being evaluated for data integrity, completeness, reliability and validity. In addition, initial efforts to evaluate, standardize, and use this data to support investigations of interest over the past year are presented.
