At many institutions, the department of emergency medicine is uniquely suit
ed to a leadership role in the deployment of new clinical decision support
systems (computer systems that support clinical practice). Many factors fav
or such a leadership role, including institutional politics, organizational
structure, extent of local control, clinician solidarity, openness to chan
ge, departmental size and scale, and willingness to take risks. Such a role
should be undertaken in partnership with the institution's information ser
vices (IS) department, and a clear understanding of goals and responsibilit
ies will facilitate such a partnership. A leadership position with respect
to new information systems entails a certain risk, but the potential benefi
t to an emergency department in today's competitive environment is substant
ial. The authors' experience with one such collaborative development projec
t is presented.
