The politics of healthcare informatics: knowledge management using an electronic medical record system.

The design and implementation of an electronic medical record system pose significant epistemological and practical complexities. Despite optimistic assessments of their potential contribution to the quality of care, their implementation has been problematic, and their actual employment in various clinical settings remains controversial. Little is known about how their use actually mediates knowing. Employing a variety of qualitative research methods, this article attempts an answer by illustrating how omitting, editing and excessive reporting were employed as part of nurses' and physicians' political efforts to shape knowledge production and knowledge sharing in a technologically mediated healthcare setting.
