The Environment

The environment in which the EHR is deployed is multi-faceted and complex. The healthcare provider system is comprised of multiple organizations and independent professionals. Only when EHRs are integrated such that information is shared among providers for access anywhere at any point in time, will healthcare be able to realize improved care delivery, reduced variation in clinical care, reduction of redundancies in testing, and reduction in the rate of increase in the cost of healthcare. This section of the HIMSS Health IT Body of Knowledge offers an overview of the healthcare environment and of the major structural elements of information technology: the electronic health record (EHR), personal health record (PHR), health information exchange (HIE) and national health information network (NHIN).
