Effect of the implementation of an enterprise-wide Electronic Health Record on productivity in the Veterans Health Administration.

Since 1995, the Veterans Health Administration (VHA) has had an ongoing process of systems improvement that has led to dramatic improvement in the quality of care delivered. A major component of the redesign of the VHA has been the creation of a fully developed enterprise-wide Electronic Health Record (EHR). VHA's Health Information Technology was developed in a collaborative fashion between local clinical champions and central software engineers.
