Psychiatric services have shifted dramatically in the past decade, largely in response to economic sur
vival. Services once delivered solely on an inpatient basis are now delivered through partial hospital
ization and day treatment programs, intensive outpatient programs, and community-based centers. Few
of these program changes, however, are developed on the basis of research or outcomes data, despite
the embraced expectation for such data. This article argues the critical need for evidence-based prac
tice and outlines steps for establishing a successful program of study. The authors share their experi
ences and lessons learned in initiating a psychiatric outcomes program. Collaboration and use of
advanced practice nurses are highlighted. (J Am Psychiatr Nurses Assoc [2000]. 6, 112-118.)
