Computerized provider order entry system field research: the impact of contextual factors on study implementation.

ABSTRACT

Attention to contextual factors is essential to the conduct of high quality informatics field research. This is particularly true when the research focus is on complex information technology innovations like computerized provider order entry (CPOE) systems. From a field research perspective, CPOE systems are considered an organizational intervention. They are designed, implemented and used within an organizational context that encompasses cultural, economic, social and physical aspects. It is essential that informatics researchers address contextual factors when assessing the impact of CPOE systems. Inclusion of organizational contextual factors in CPOE system field studies permits a more accurate evaluation of the true impact these systems have on medication practice processes and outcomes. The goals of this paper are to (1) identify contextual factors that influenced implementation of a federally-funded field study undertaken to examine the impact of a community hospital CPOE system on medication error outcomes; and (2) describe how these contextual factors influenced study methodology and implementation.
