About VistA EHR

The Veterans Health Information Systems and Technology Architecture (Vista) is an enterprise-wide information system built around  Electronic Health Records (EHR), used by the United States Department of Veterans Affairs (VA) medical system which consists of nearly 160 integrated software modules for clinical care, financial functions, and infrastructure.

The VHA manages the largest medical system in the United States, providing care to over 8 million veterans, employing 180,000 medical personnel, and operating 163 hospitals, more than 800 clinics, and 135 nursing homes on a single electronic healthcare information network throughout the continental US, Alaska, and Hawaii.

 

 

 

 
     
 

VistA Electronic Health Records (EHR)

 

The health information system developed by the US Department of Veterans Affairs:

 

Nearly 25% of the USA’s population is potentially eligible for VA benefits and services because they are veterans, family members, or survivors of veterans. 

 

Over 60% of all physicians trained in the US rotate through the VHA on clinical electives, making VistA the most familiar and widely used EHR in the US. 

 

Nearly half of hospitals that have a  xcomplete (inpatient/outpatient)enterprise-wide implementation of an EHR are VA hospitals using VistA.

VistA supports both ambulatory and inpatient care, and includes several significant enhancements to the original DHCP system. The most significant is a graphical user interface for clinicians known as the Computerized Patient Record System (CPRS); which was released in 1997. In addition, VistA includes computerized order entry, bar code medication administration, electronic prescribing, and clinical guidelines.

CPRS provides a client–server interface that allows health care providers to review and update a patients electronic medical record. This includes the ability to place orders, including those for medications, special procedures, X-rays, nursing interventions, diets, and laboratory tests. CPRS provides flexibility to a wide variety of settings, so that a consistent, event-driven, windows-style interface is presented to a broad spectrum of health care workers.
