Medical order entry systems, also called computerized provider order entry systems (CPOE) are a component of an electronic health record and are defined as "information systems, usually computer-assisted, that enable providers to initiate medical procedures, prescribe medications, etc. These systems support medical decision-making and error-reduction during patient care."[1]

In the United States, the CPOE of the Veterans Health Administration, called VISTA/CPRS supports 'order dialogs', 'quick orders', and 'order sets'.[2]

CPOE can be used as a type clinical decision support system whose benefits can be shown in a randomized controlled trial[3] and other studies[4][5].

CPOE is one of the four recommendations by the Leapfrog Group.[6]

Since nurses will be a major consumer of CPOE output, any successful system will be consistent with nursing workflow.
