The United States Veterans Administration was one of the earliest organizations to adopt MUMPS as the programming language for a major project. Their early projects, and contributions to the library of free MUMPS code, are still being used today.

Veterans Administration and Department of Defense[edit]

The Veterans Administration (now called the United States Department of Veterans Affairs) officially adopted MUMPS as the programming language to be used while implementing a hospital information system in the early 1980s. The original version, the Decentralized Hospital Computer Program (DHCP) was delivered early and under budget. Before implementing DHCP, the VA also wrote a DBMS for MUMPS, called FileMan. Today, the most recent expanded release of DHCP is known as Veterans Health Information Systems and Technology Architecture (VistA). All three systems are available in source code for use in compatible applications. Both have won awards for efficiency and innovation, VistA as recently as 2006.

The VA hired SAIC to do two pilot projects, converting from the algorithms from MUMPS to a Java/web based solution. The projects were canceled, but one of the pilots was completed. The completed project converted the MUMPS code to functionally equivalent, web-enabled Java. This pilot is open source and can still be acquired from the VA.

Nearly the entire VA hospital system in the United States, the Indian Health Service, as well as major parts of the Department of Defense CHCS hospital system run systems using MUMPS databases for clinical data tracking. These are built on Intersystem's Caché platform. These uses are among the most significant computer applications in the world in terms of number of facilities, number of people tracked, geographical dispersion of sites using the software, ...

Health care industry[edit]

Large companies currently using MUMPS include AmeriPath (now part of Quest Diagnostics), Care Centric, Team Health, Epic, EMIS, Partners HealthCare, Meditech, GE Healthcare (formerly IDX Systems and Centricity), and Sunquest Information Systems (formerly Misys Healthcare). Many reference laboratories, such as Quest Diagnostics and Dynacare, use MUMPS software written or based on by Antrim Corporation code, which was purchased by Sunquest in 2001.[1]

Coventry Healthcare and Massachusetts Hospital have also been reported to use MUMPS.

Other industries[edit]

MUMPS gained an early following in the financial sector, and MUMPS applications are in use at many banks and credit unions. For instance, it is used by Ameritrade, the largest online trading service in the US with over 12 billion transactions per day, as well as by the Bank of England and Barclays Bank, among others.[2][3][4]

As of 2005 most use of M is either in the form of GT.M or InterSystems Caché. The latter is being aggressively marketed by InterSystems and has had some success in penetrating new markets, such as telecommunications.
